RESUMEN

OBJECTIVES: This study aims to 1) identify the relation between walking ability and participation after stroke and 2) explore whether change in walking ability is associated with change in participation over time in community living-people after stroke. MATERIALS AND METHODS: Fifty-two people after stroke were assessed at baseline and after a 6-week gait training intervention. People were included between two weeks and six months after stroke. The Utrecht Scale for Evaluation of Rehabilitation-Participation was used to measure participation. Assessment of walking ability included the six-minute walking test for walking endurance, Timed-up & Go test for functional mobility, Mini Balance Evaluation Systems Test for dynamic balance, and total duration of walking activity per day to measure walking activity. RESULTS: At baseline, six-minute walking test, Timed-up & Go test, and Mini Balance Evaluation Systems Test were univariately associated with participation (P < 0.001). Backward multiple regression analysis showed that the Mini Balance Evaluation Systems Test independently explained 55.7% of the variance in participation at baseline. Over time, only change in the six-minute walking test was positively associated with change in participation (R2 = 0.087, P = 0.040). CONCLUSIONS: Cross-sectional associations showed that walking ability, and especially dynamic balance, contributes to participation after stroke. Dynamic balance, as underlying variable for walking, was an important independently related factor to participation after stroke which needs attention during rehabilitation. Longitudinally, improvement in walking endurance was significantly associated with improvement in participation, which indicates the relevance of training walking endurance to improve participation after stroke.

RESUMEN

OBJECTIVE: After stroke, people experience difficulties with walking that lead to restrictions in participation in daily life. The purpose of this study was to examine the effect of virtual reality gait training (VRT) compared to non-virtual reality gait training (non-VRT) on participation in community-living people after stroke. METHODS: In this assessor-blinded, randomized controlled trial with 2 parallel groups, people were included between 2 weeks and 6 months after stroke and randomly assigned to the VRT group or non-VRT group. Participants assigned to the VRT group received training on the Gait Real-time Analysis Interactive Lab (GRAIL), and participants assigned to the non-VRT group received treadmill training and functional gait exercises without virtual reality. Both training interventions consisted of 12 30-minute sessions during 6 weeks. The primary outcome was participation measured with the restrictions subscale of the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P) 3 months postintervention. Secondary outcomes included subjective physical functioning, functional mobility, walking ability, dynamic balance, walking activity, fatigue, anxiety and depression, falls efficacy, and quality of life. RESULTS: Twenty-eight participants were randomly assigned to the VRT group and 27 to the non-VRT group, of whom 25 and 22 attended 75% or more of the training sessions, respectively. No significant differences between the groups were found over time for the USER-P restrictions subscale (1.23; 95% CI = -0.76 to 3.23) or secondary outcome measures. Patients' experiences with VRT were positive, and no serious adverse events were related to the interventions. CONCLUSIONS: The effect of VRT was not statistically different from non-VRT in improving participation in community-living people after stroke. IMPACT: Although outcomes were not statistically different, treadmill-based VRT was a safe and well-tolerated intervention that was positively rated by people after stroke. VR training might, therefore, be a valuable addition to stroke rehabilitation. LAY SUMMARY: VRT is feasible and was positively experienced by people after stroke. However, VRT was not more effective than non-VRT for improving walking ability and participation after stroke.

RESUMEN

Background: An important focus of post-stroke physical therapy is to improve walking and walking capacity. However, many people after stroke experience difficulties with gait-related participation, which includes more than walking capacity alone. Gait-related participation involves walking with a participation goal and requires to deal with changes in the environment during walking and perform dual tasks, for example.Objective: To explore barriers and facilitators for gait-related participation from the perspective of people after stroke. This knowledge can contribute to the development of effective interventions to improve gait-related participation.Methods: Semi-structured interviews were conducted to investigate how people after stroke experience gait-related participation. Audio-recorded interviews were transcribed, anonymized, and analyzed thematically. Barriers and facilitators were categorized according to the International Classification of Functioning, Disability and Health (ICF) framework.Results: Twenty-one people after stroke participated. Median age was 65 years, median time since stroke 16 weeks. Barriers were reported in movement-related functions, cognitive functions, mobility, personal factors, and environmental factors. Facilitators were found on participation level and in personal and environmental factors, such as motivation and family support.Conclusion: People after stroke who were physically able to walk independently still described multiple barriers to gait-related participation in all components of the ICF framework.

RESUMEN

OBJECTIVE: To examine the effectiveness of Brains Ahead!, a psychoeducational intervention aimed to prevent long-term problems with activities and participation in children after mild traumatic brain injury (mTBI). PARTICIPANTS: In total, 124 children, aged 6 to 18 years, diagnosed with mTBI and their caregivers. METHOD: After randomization, participants in the intervention group received a face-to-face psychoeducational session with written take-home information and follow-up telephone call(s). Participants in the control group received usual care, consisting of a concise information brochure. PRIMARY OUTCOME MEASURES: Activities and participation (Child and Adolescent Scale of Participation [CASP]). SECONDARY OUTCOMES: fatigue, postconcussive symptoms (PCSs), posttraumatic stress symptoms (PTSSs), and quality of life (QOL). RESULTS: Generalized Estimated Equation analyses showed that both groups improved over the first 6 months post-mTBI, but the intervention group did not differ significantly on the CASP. Mann-Whitney U tests showed that the intervention group reported significantly less fatigue, PCSs, and PTSSs and better QOL compared with the control group at 6 months post-MTBI. CONCLUSIONS: The Brains Ahead! intervention resulted in significant improvements compared with usual care in reducing fatigue, PCSs, and PTSSs and improving QOL. Lack of an effect on activities and participation may be due to the ceiling effect of the CASP.

RESUMEN

OBJECTIVE: To investigate the natural course of activities and participation of children up to 6 months after a mild traumatic brain injury (mTBI). METHODS: A prospective longitudinal cohort study with complete data sets of 231 children diagnosed with mTBI and their caregivers. MAIN MEASURES: Activities and participation assessed with the Child and Adolescent Scale of Participation (CASP) and the Children's Assessment of Participation and Enjoyment (CAPE) measured at 2 weeks, 3 months, and 6 months post-mTBI. Because of a ceiling effect, the primary outcome measure (CASP) was divided into deviant (not maximum score) or full functioning. RESULTS: Friedman's, Cochran's Q, and McNemar's tests (CASP) and repeated-measures analyses of variance (CAPE) showed significant increases in activities and participation between 2 weeks and 3 and 6 months after mTBI. Based on the parents' perspective, 67% of the children returned to full functioning at 6 months postinjury, with only 38% of the children describing themselves as functioning at their premorbid level. DISCUSSION: Findings indicate that most children return to maximum level of activities and participation over time after mTBI. In a substantial number of children, however, the level of activities and participation at 6 months postinjury is evaluated as lower than that of peers. The importance of investigating predictors for child and caregiver perspectives is emphasized.

RESUMEN

Background: Impairments in arm function are a common problem in stroke survivors and have a large impact on health-related quality of life (HRQoL). Little is known about the longitudinal relationship between recovery of upper limb strength and changes in HRQoL. Objectives: This study aimed to determine to what extent changes in HRQoL are related to changes in upper limb strength after discharge from inpatient rehabilitation. Methods: 250 patients from an RCT were assessed at discharge from inpatient rehabilitation (baseline) and at 12 weeks post-discharge (follow-up). The Stroke Impact Scale was used to measure HRQoL, and the Motricity Index Arm was used to measure upper limb strength. Hierarchical regression analysis was performed to determine the predictive value of upper limb strength on HRQoL, relative to demographic and clinical characteristics. Regression analysis was used to determine the relation between upper limb strength improvement and HRQoL improvement. Results: Upper limb strength at baseline was a major predictor of HRQoL at follow-up, after accounting for demographic and clinical characteristics (p < .05). Improvement in HRQoL was positively related to improvement in upper limb strength (F(1, 240) = 18.351, p <.0005). Conclusions: These findings highlight the importance of upper limb strength in HRQoL, as HRQoL is associated with improvement in upper limb strength recovery. Better monitoring of recovery and treatment of upper limb strength during the outpatient rehabilitation period and beyond, i.e. outside the typical time-window of recovery in the first 3 months post-stroke, might contribute to higher quality of life for stroke survivors.

RESUMEN

OBJECTIVE: This study aimed to identify predictors of long-term consequences for activities and participation in children and adolescents with mild traumatic brain injury (mTBI). METHODS: A multicentre prospective longitudinal cohort study was conducted. The primary outcome measure was activities and participation measured with the Child and Adolescent Scale of Participation - CASP and completed by children (N = 156) and caregivers (N = 231) six months post-mTBI. The CASP items were categorized into home, community, school, and environment. Predictors were categorized according to the International Classification of Functioning, Disability and Health for Children and Youth. Predictors included pre-injury personal- and environmental factors, injury-related factors, symptoms, and resumption of activities in the first two weeks after mTBI. Univariate and multivariate logistic regression analyses were used to determine the predictive value of these factors. RESULTS: Results show that predictors differ across settings and perspectives (child or caregiver). Decreased activities and participation in children with mTBI can be predicted by adverse pre-injury behavioral functioning of the child (p < .000 - p = .038), adverse pre-injury family functioning (p = .001), lower parental SES (p = .038), more stress symptoms post-injury (p = .017 - p = .032), more post-concussive symptoms (p = .016 - p = .028) and less resumption of activities (p = .006 - p = .045). DISCUSSION: Pre-injury factors, more symptoms post-injury and less resumption of activities should be considered when children are screened for unfavorable outcomes. Additional factors may add to the prediction, but injury-related factors do not. It is recommended that future research explores psychosocial factors, such as coping styles, emotion-regulation, personality traits, social support, and other comorbid problems of both children and caregivers.

RESUMEN

OBJECTIVE: To classify patients with stroke into subgroups based on their characteristics at the moment of discharge from inpatient rehabilitation in order to predict community ambulation outcome 6 months later. DESIGN: Prospective cohort study with a baseline measurement at discharge from inpatient care and final outcome determined after 6 months. SETTING: Community. PARTICIPANTS: A cohort of patients (N=243) with stroke, referred for outpatient physical therapy, after completing inpatient rehabilitation in The Netherlands. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A classification model was developed using Classification And Regression Tree (CART) analysis. Final outcome was determined using the community ambulation questionnaire. Potential baseline predictors included patient demographics, stroke characteristics, use of assistive devices, comfortable gait speed, balance, strength, motivation, falls efficacy, anxiety, and depression. RESULTS: The CART model accurately predicted independent community ambulation in 181 of 193 patients with stroke, based on a comfortable gait speed at discharge of 0.5 meters per second or faster. In contrast, 27 of 50 patients with gait speeds below 0.5 meters per second were correctly predicted to become noncommunity walkers. CONCLUSIONS: We show that comfortable gait speed is a key factor in the prognosis of community ambulation outcome. The CART model may support clinicians in organizing community services at the moment of discharge from inpatient care.

RESUMEN

A recent review indicated that perturbation-based training (PBT) interventions are effective in reducing falls in older adults and patients with Parkinson's disease. It is unknown whether this type of intervention is effective in stroke survivors. We determined whether PBT can enhance gait stability in stroke survivors. A total of 10 chronic stroke survivors who experienced falls in the past 6 months participated in the PBT. Participants performed 10 training sessions over a 6-week period. The gait training protocol was progressive, and each training contained unexpected gait perturbations and expected gait perturbations. Evaluation of gait stability was performed by determining steady-state gait characteristics and daily-life gait characteristics. We previously developed fall prediction models for both gait assessment methods. We evaluated whether predicted fall risk was reduced after PBT according to both models. Steady-state gait characteristics significantly improved, and consequently, predicted fall risk was reduced after the PBT. However, daily-life gait characteristics did not change, and thus, predicted fall risk based on daily-life gait remained unchanged after the PBT. A PBT resulted in more stable gait on a treadmill and thus lower predicted fall risk. However, the more stable gait on the treadmill did not transfer to a more stable gait in daily life.

RESUMEN

BACKGROUND: A stroke often results in gait impairments, activity limitations and restricted participation in daily life. Virtual reality (VR) has shown to be beneficial for improving gait ability after stroke. Previous studies regarding VR focused mainly on improvements in functional outcomes. As participation in daily life is an important goal for rehabilitation after stroke, it is of importance to investigate if VR gait training improves participation. The primary aim of this study is to examine the effect of VR gait training on participation in community-living people after stroke. METHODS/DESIGN: The ViRTAS study comprises a single-blinded, randomized controlled trial with two parallel groups. Fifty people between 2 weeks and 6 months after stroke, who experience constraints with walking in daily life, are randomly assigned to the virtual reality gait training (VRT) group or the non-virtual reality gait training (non-VRT) group. Both training interventions consist of 12 30-min sessions in an outpatient rehabilitation clinic during 6 weeks. Assessments are performed at baseline, post intervention and 3 months post intervention. The primary outcome is participation measured with the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P). Secondary outcomes are subjective physical functioning, functional mobility, walking ability, walking activity, fatigue, anxiety and depression, falls efficacy and quality of life. DISCUSSION: The results of the study provide insight into the effect of VR gait training on participation after stroke. TRIAL REGISTRATION: Netherlands National Trial Register, Identifier NTR6215 .

RESUMEN

INTRODUCTION: Stroke survivors often fall during walking. To reduce fall risk, gait testing and training with avoidance of virtual obstacles is gaining popularity. However, it is unknown whether and how virtual obstacle crossing is associated with fall risk. AIM: The present study assessed whether obstacle crossing characteristics are reliable and assessed differences in stroke survivors who prospectively experienced falls or no falls. METHOD: We recruited twenty-nine community dwelling chronic stroke survivors. Participants crossed five virtual obstacles with increasing lengths. After a break, the test was repeated to assess test-retest reliability. For each obstacle length and trial, we determined; success rate, leading limb preference, pre and post obstacle distance, margins of stability, toe clearance, and crossing step length and speed. Subsequently, fall incidence was monitored using a fall calendar and monthly phone calls over a six-month period. RESULTS: Test-retest reliability was poor, but improved with increasing obstacle-length. Twelve participants reported at least one fall. No association of fall incidence with any of the obstacle crossing characteristics was found. DISCUSSION: Given the absence of height of the virtual obstacles, obstacle avoidance may have been relatively easy, allowing participants to cross obstacles in multiple ways, increasing variability of crossing characteristics and reducing the association with fall risk. CONCLUSION: These finding cast some doubt on current protocols for testing and training of obstacle avoidance in stroke rehabilitation.

RESUMEN

PURPOSE: To determine the roles of calcium (Ca2+) handling by sarcoplasmic reticulum (SR) and central activation impairment (i.e., central fatigue) during fatigue with repeated maximal voluntary isometric contractions (MVC) in human muscles. METHODS: Contractile performance was assessed during 3 min of repeated MVCs (7-s contraction, 3-s rest, n = 17). In ten participants, in vitro SR Ca2+-handling, metabolites, and fibre-type composition were quantified in biopsy samples from quadriceps muscle, along with plasma venous [K+]. In 11 participants, central fatigue was compared using tetanic stimulation superimposed on MVC in quadriceps and adductor pollicis muscles. RESULTS: The decline of peak MVC force with fatigue was similar for both muscles. Fatigue resistance correlated directly with % type I fibre area in quadriceps (r = 0.77, P = 0.009). The maximal rate of ryanodine-induced Ca2+-release and Ca2+-uptake fell by 31 ± 26 and 28 ± 13%, respectively. The tetanic force depression was correlated with the combined reduction of ATP and PCr, and increase of lactate (r = 0.77, P = 0.009). Plasma venous [K+] increased from 4.0 ± 0.3 to 5.4 ± 0.8 mM over 1-3-min exercise. Central fatigue occurred during the early contractions in the quadriceps in 7 out of 17 participants (central activation ratio fell from 0.98 ± 0.05 to 0.86 ± 0.11 at 1 min), but dwindled at exercise cessation. Central fatigue was seldom apparent in adductor pollicis. CONCLUSIONS: Fatigue with repeated MVC in human limb muscles mainly involves peripheral aspects which include impaired SR Ca2+-handling and we speculate that anaerobic metabolite changes are involved. A faster early force loss in quadriceps muscle with some participants is attributed to central fatigue.

RESUMEN

OBJECTIVE: This exploratory study investigated to what extent gait characteristics and clinical physical therapy assessments predict falls in chronic stroke survivors. DESIGN: Prospective study. SUBJECTS: Chronic fall-prone and non-fall-prone stroke survivors. METHODS: Steady-state gait characteristics were collected from 40 participants while walking on a treadmill with motion capture of spatio-temporal, variability, and stability measures. An accelerometer was used to collect daily-life gait characteristics during 7 days. Six physical and psychological assessments were administered. Fall events were determined using a "fall calendar" and monthly phone calls over a 6-month period. After data reduction through principal component analysis, the predictive capacity of each method was determined by logistic regression. RESULTS: Thirty-eight percent of the participants were classified as fallers. Laboratory-based and daily-life gait characteristics predicted falls acceptably well, with an area under the curve of, 0.73 and 0.72, respectively, while fall predictions from clinical assessments were limited (0.64). CONCLUSION: Independent of the type of gait assessment, qualitative gait characteristics are better fall predictors than clinical assessments. Clinicians should therefore consider gait analyses as an alternative for identifying fall-prone stroke survivors.

RESUMEN

BACKGROUND: Steady-state gait characteristics appear promising as predictors of falls in stroke survivors. However, assessing how stroke survivors respond to actual gait perturbations may result in better fall predictions. We hypothesize that stroke survivors who fall have a diminished ability to adequately adjust gait characteristics after gait is perturbed. This study explored whether gait characteristics of perturbed gait differ between fallers and non fallers. METHOD: Chronic stroke survivors were recruited by clinical therapy practices. Prospective falls were monitored over a six months follow up period. We used the Gait Real-time Analysis Interactive Lab (GRAIL, Motekforce Link B.V., Amsterdam) to assess gait. First we assessed gait characteristics during steady-state gait and second we examined gait responses after six types of gait perturbations. We assessed base of support gait characteristics and margins of stability in the forward and medio-lateral direction. FINDINGS: Thirty eight stroke survivors complete our gait protocol. Fifteen stroke survivors experienced falls. All six gait perturbations resulted in a significant gait deviation. Forward stability was reduced in the fall group during the second step after a ipsilateral perturbation. INTERPRETATION: Although stability was different between groups during a ipsilateral perturbation, it was caused by a secondary strategy to keep up with the belt speed, therefore, contrary to our hypothesis fallers group of stroke survivors have a preserved ability to cope with external gait perturbations as compared to non fallers. Yet, our sample size was limited and thereby, perhaps minor group differences were not revealed in the present study.

RESUMEN

BACKGROUND: Acute lateral ankle ligamentous sprains (ALALS) are common injuries. This injury does not always have a favourable long-term outcome. Studies reporting the prognosis of ALALS after functional treatment are scarce. OBJECTIVE: To determine the prognosis of functionally treated ALALS, in terms of recurrent ALALS and residual symptoms. STUDY DESIGN: Retrospective cohort study. SETTING: Patients were recruited from 20 family practices, nine physical therapy practices, the emergency departments of a regional hospital and a university hospital. PATIENTS: Adult patients with an ALALS caused by an inversion trauma were invited to participate in this study 2.5-5 years after their initial injury. INDEPENDENT VARIABLES: Functional treatment of the initial ALALS. MAIN OUTCOME MEASURES: Acute lateral ankle ligamentous sprain recurrences and residual symptoms. RESULTS: A total of 44 patients were included, with an average follow-up period after the initial ankle sprain of 204 weeks (range 150-274 weeks). Eight patients (18.1%) had reinjured their ankle. Explicit pain around the ankle joint at physical examination was experienced by 45.5%. Clinical symptoms of anterior ankle impingement were present in 25% (all athletes), with radiologically confirmed tibiotalar osteophyte bone formation in 82% of them. CONCLUSIONS: A large proportion of patients with ALALS experience recurrences and persistent symptoms after their initial ankle injury. The high percentage of patients with anterior ankle impingement syndromes illustrates the need for early assessment of this impairment in patients with persistent complaints.

RESUMEN

BACKGROUND: Falls in stroke survivors can lead to serious injuries and medical costs. Fall risk in older adults can be predicted based on gait characteristics measured in daily life. Given the different gait patterns that stroke survivors exhibit it is unclear whether a similar fall-prediction model could be used in this group. Therefore the main purpose of this study was to examine whether fall-prediction models that have been used in older adults can also be used in a population of stroke survivors, or if modifications are needed, either in the cut-off values of such models, or in the gait characteristics of interest. METHODS: This study investigated gait characteristics by assessing accelerations of the lower back measured during seven consecutive days in 31 non fall-prone stroke survivors, 25 fall-prone stroke survivors, 20 neurologically intact fall-prone older adults and 30 non fall-prone older adults. We created a binary logistic regression model to assess the ability of predicting falls for each gait characteristic. We included health status and the interaction between health status (stroke survivors versus older adults) and gait characteristic in the model. RESULTS: We found four significant interactions between gait characteristics and health status. Furthermore we found another four gait characteristics that had similar predictive capacity in both stroke survivors and older adults. CONCLUSION: The interactions between gait characteristics and health status indicate that gait characteristics are differently associated with fall history between stroke survivors and older adults. Thus specific models are needed to predict fall risk in stroke survivors.

RESUMEN

BACKGROUND: Virtual reality (VR) training is considered to be a promising novel therapy for balance and gait recovery in patients with stroke. PURPOSE: The aim of this study was to conduct a systematic literature review with meta-analysis to investigate whether balance or gait training using VR is more effective than conventional balance or gait training in patients with stroke. DATA SOURCES: A literature search was carried out in the databases PubMed, Embase, MEDLINE, and Cochrane Library up to December 1, 2015. STUDY SELECTION: Randomized controlled trials that compared the effect of balance or gait training with and without VR on balance and gait ability in patients with stroke were included. DATA EXTRACTION AND SYNTHESIS: Twenty-one studies with a median PEDro score of 6.0 were included. The included studies demonstrated a significant greater effect of VR training on balance and gait recovery after stroke compared with conventional therapy as indicated with the most frequently used measures: gait speed, Berg Balance Scale, and Timed "Up & Go" Test. Virtual reality was more effective to train gait and balance than conventional training when VR interventions were added to conventional therapy and when time dose was matched. LIMITATIONS: The presence of publication bias and diversity in included studies were limitations of the study. CONCLUSIONS: The results suggest that VR training is more effective than balance or gait training without VR for improving balance or gait ability in patients with stroke. Future studies are recommended to investigate the effect of VR on participation level with an adequate follow-up period. Overall, a positive and promising effect of VR training on balance and gait ability is expected.

RESUMEN

BACKGROUND: Approximately 20 % of children and adolescents who have sustained mild traumatic brain injuries may experience long-term consequences, including cognitive problems, post-traumatic stress symptoms and reduced load-bearing capacity. The underestimation and belated recognition of these long-term consequences may lead to chronic and disruptive problems, such as participation problems in school and in social relationships. The aim of this study is to examine the level of activities and participation of children and adolescents up to 6 months after a mild traumatic brain injury and to identify possible outcome predictors. Another aim is to investigate the effectiveness of an early psychoeducational intervention and compare the results with those obtained with usual care. METHODS/DESIGN: This paper presents the Brains Ahead! study design, a randomised controlled trial nested within a multicentre, longitudinal, prospective cohort study. The eligible participants include children and adolescents between 6 and 18 years of age who have experienced a mild traumatic brain injury within the last 2 weeks. The cohort study will include 500 children and adolescents with a mild traumatic brain injury and their caregivers. A subset of 140 participants and their caregivers will be included in the randomised controlled trial. Participants in the randomised controlled trial will be randomly assigned to either the psychoeducational intervention group or the usual care control group. The psychoeducational intervention involves one face-to-face contact and one phone contact with the interventionist, during which the consequences of mild traumatic brain injury and advice for coping with these consequences to prevent long-term problems will be discussed. Information will be provided both verbally and in a booklet. The primary outcome domain is activities and participation, which will be evaluated using the Child and Adolescent Scale of Participation. Participants are evaluated 2 weeks, 3 months and 6 months after the mild traumatic brain injury. DISCUSSION: The results of this study will provide insight into which children with mild traumatic brain injury are at risk for long-term participation problems and may benefit from a psychoeducational intervention.

RESUMEN

OBJECTIVE: To systematically review the use of cardiopulmonary exercise testing in people who have survived a stroke. The following questions are addressed: (i) What are the testing procedures used? (ii) What are the patient, safety and outcomes characteristics in the cardiopulmonary exercise testing procedures? (iii) Which criteria are used to determine maximum oxygen uptake (VO2peak/max) in the cardiopulmonary exercise testing procedures? METHODS: Systematic review of studies of cardiopulmonary exercise testing in stroke survivors. PubMed, EMBASE, and CINAHL were searched from inception until January 2014. MeSH headings and keywords used were: oxygen capacity, oxygen consumption, oxygen uptake, peak VO2, max VO2, aerobic fitness, physical fitness, aerobic capacity, physical endurance and stroke. Search and selection were performed independently by 2 reviewers. Sixty studies were scrutinized, including 2,104 stroke survivors. RESULTS: Protocols included treadmill (n = 21), bicycle (n = 33), stepper (n = 3) and arm (n = 1) ergometry. Five studies reported 11 adverse events (1%). Secondary outcomes were reported in few studies, which hampered interpretation of the patient's effort, and hence the value of the VO2peak. CONCLUSION: Most studies did not adhere, or insufficiently adhered, to the existing cardiopulmonary exercise testing guidelines for exercise testing. Thus, the results of cardiopulmonary exercise testing protocols in stroke patients cannot be compared.

RESUMEN

STUDY DESIGN: Systematic literature review. OBJECTIVE: To summarize the evidence for physical therapist-guided quadriceps-strengthening exercises as a treatment for patellofemoral pain syndrome. BACKGROUND: Although quadriceps strengthening is often included in the plan of care for patellofemoral pain syndrome, a systematic review published in 2003 found only limited evidence that exercise was more effective than no exercise for this common condition. METHODS: The PubMed, Embase/MEDLINE, and Cochrane Central Register of Controlled Trials databases, from inception to January 9, 2014, were searched for randomized controlled trials comparing the use of quadriceps-strengthening exercises to interventions consisting of advice/information or a placebo. Outcomes of interest were pain measures and function, as measured with self-report questionnaires. The methodological quality of the randomized controlled trials was assessed with the Physiotherapy Evidence Database scale. Results were summarized using a best-evidence synthesis and graphically illustrated using forest plots without meta-analysis. RESULTS: Seven studies were included in the literature review. These studies reported strong evidence that isolated quadriceps strengthening is more effective in reducing pain and improving function than advice and information alone. In addition, compared to advice and information or placebo, there was strong evidence that quadriceps-strengthening exercises combined with other interventions may be more effective in reducing pain immediately postintervention and after 12 months, but not in improving function. CONCLUSION: The literature provides strong evidence for the use of quadriceps-strengthening exercises, with or without other interventions, for the treatment of patellofemoral pain syndrome.
