RESUMEN

BACKGROUND: Patients experience falls frequently after stroke. Preserved or acquired balance skills decrease fall risk and improve independence. Feasibility of Fullerton Advanced Balance Scale (FAB) has been shown in balance assessment in some neurological diseases except stroke. OBJECTIVES: The purpose of this study was to investigate the reliability and validity of Turkish version of FAB (FAB-T) in patients with stroke (PwS). METHODS: This cross-sectional study included 51 PwS (60.64 ± 7.66 years). Reliability analyses were conducted with Cronbach's alpha, intraclass correlation coefficient (ICC), and Spearman correlation analysis. Intra-rater and inter-rater reliability were assessed with three raters. FAB-T, Stroke Rehabilitation Assessment of Movement (STREAM), Brunnstrom Recovery Stages (BRS), Barthel Index (BI), and 36-Item Short Form Health Survey (SF-36) were used for convergent validity. Correlations of FAB-T with Berg Balance Scale (BBS) and Mini-Balance Evaluation Systems Test (Mini-BESTest) were measured for concurrent validity. Spearman correlation analysis was used for convergent and concurrent validity. For predictive validity patients' self-reports of falling were analyzed with ROC. RESULTS: Intra-rater (ICC = 0.998) and inter-rater reliability (ICCs = 0.984; 0.984; 0.990), and internal consistency (Cronbach's alpha = 0.930) were excellent. FAB-T had good correlations with STREAM (ρ = 0.677) and BI (ρ = 0.628), moderate correlations with BRS (ρ = 0.504 and ρ = 0.579) and physical function of SF-36 (ρ = 0.436). FAB-T excellently correlated with Mini-BESTest and BBS (ρ = 0.928 and ρ = 0.942). The cutoff score of FAB-T was determined to be 21.5 points, with sensitivity of 84% and specificity of 61% (AUC = 0.749). CONCLUSIONS: FAB-T is a reliable and valid balance assessment tool with an acceptable accuracy of fall prediction in PwS.

RESUMEN

PURPOSE: This study was conducted to evaluate the reliability and validity of the Fullerton Advanced Balance Scale (FAB) in people with Multiple Sclerosis (PwMS). METHODS: A total of 65 people with multiple sclerosis, Expanded Disability Status Scale (EDSS) ranging from 1 to 5.5, were included in the study. Test-retest reliability, intra-rater, inter-rater reliability, and internal consistency (item-total score correlation, Cronbach's alpha coefficient) were investigated to examine the reliability of FAB. In the intra-rater and inter-rater reliability analysis, the FAB application of 34 patients, whose initial evaluation was gathered, was video-recorded and re-watched by two physiotherapists at different times and scored. For the Validity of FAB, concurrent validity with criterion validity; construct validity with hypothesis testing were calculated. Convergent validity was assessed for correlations with EDDS, Dynamic Gait Index (DGI), and Timed Up and Go Test (TUG). RESULTS: Test-retest reliability of FAB Intraclass Correlation Coefficient (ICC) values was excellent (ICC= 0.994, p < 0.001). While the intra-rater reliability (ICC=0.986, p < 0.001) and inter-rater reliability (ICC=0.985, p < 0.001) of the FAB were calculated at an excellent level. Cronbach's alpha value was determined to perfect correlation. (Cronbach's alpha coefficient: 0.929). FAB had an excellent correlation with BBS (0.919 (p < 0.001). For convergent validity of FAB, EDSS (r=-0.885, p < 0.001), TUG (r=-0.833, p < 0.001), and DGI (r = 0.916, p < 0.001), it was determined that the scale had convergent validity. CONCLUSION: The FAB proved to be a reliable and valid in PwMS. The study showed that the FAB could be applied regardless of the physiotherapists' clinical experiences. It has been determined that the scale can be used in PwMS with a wide EDSS score. Considering the inter-rater and intra-rater reliability results, it is thought that the FAB is also suitable for use in the online environment.

RESUMEN

The biomechanical relationship between horse and rider in equine-assisted activities and therapies has been largely unexplored. The three-dimensional stimulation of the horse's gait has potential to improve rider musculature and coordination, especially in an older adult population. This study utilized dual-axis goniometers and video motion capture tracking to simultaneously track horse and rider hip flexion and extension. Ten older adult riders participated in 8 weeks of horseback riding lessons, where pelvis kinematics and balance assessments were compared between Weeks 1 and 8. Pelvic roll of the rider and horses' hip flexion and extension were successfully tracked and summed improvements in balance assessments were also evident after 8 weeks of horseback riding lessons. Future research will assess deeper kinematic relationships between a horse's gait and rider biomechanical responses.

RESUMEN

Background: Aging increases the probability of falling. Fullerton Advanced Balance Scale is developed to assess balance and the purpose of this study is examination of the validity and reliability of Persian version of the scale in Iranian community-dwelling older adults.Methods: The "forward-backward" procedure was applied for translation. Content validity was calculated by agreement of experts. For evaluation concurrent criterion validity, correlation of Fullerton Advanced Balance Scale with Berg Balance Scale, Timed Up and Go Test, and Functional Reach Test was measured. Retrospective self-report of fall was applied for considering predictive criterion validity. For assessment of construct validity, exploratory and confirmatory factor analyses were performed. Intraclass correlation coefficient (ICC), Kappa Coefficient, standard error of measurement (SEM), and Cronbach's alpha were used to assess reliability.Results: Content validity was acceptable (0.8-1). Concurrent criterion validity was calculated moderate-good (Fullerton Advanced Balance Scale with Berg Balance Scale, Berg Balance Scale static, and Berg Balance Scale dynamic: 0.65, 0.68, and 0.44. Fullerton Advanced Balance Scale with Timed Up and Go Test and Functional Reach Test: -0.77 and 0.6, respectively). Fullerton Advanced Balance Scale had an inverse linear relationship with fall probability. In factor analysis, two factors were extracted. ICC (95% confidence interval) for both test-retest and inter-rater reliability (0.92 and 0.72-1) was excellent (0.97 and 0.92) and Kappa for both test-retest and inter-rater reliability was good. SEM at test-retest reliability (0.17) and inter-rater reliability (1.25) was good. Excellent homogeneity was got (Cronbach's alpha: 0.84).Conclusions: The Persian version of the Fullerton Advanced Balance Scale is a reliable and valid tool for measuring balance in Iranian community-dwelling older adults.Implications for rehabilitationExistence of a scale that measures the balance in high-performance individuals, as well as small changes in balance is essential in rehabilitation.Obtaining the validity and reliability of the Fullerton Advanced Balance Scale, which has the mentioned characteristics in older adults, enhances rehabilitation interventions in these population.

RESUMEN

Lymphedema following surgical treatment for breast cancer can impair balance and predispose patients to falling. Fullerton Advanced Balance (FAB) Scale is a reliable and valid tool which can identify persons with different balance levels, but its responsiveness has not been investigated in patients with lymphedema secondary to breast surgery. Thirty women with stage 2 lymphedema secondary to breast cancer treatment received complex decongestive therapy (CDT) for 2 weeks as a routine treatment method. They were evaluated with FAB Scale and Timed Up and Go Test (TUGT), volumetric measurements and circumferential measurements of the upper limbs before and after CDT. A moderate change was found in FAB score after CDT (Cohen's effect size = 0.65). For FAB, the computed standard error of the mean was 0.85 and minimal detectable change was 2.33. Significant improvement in FAB score and TUGT results, and significant reductions in circumferential and volumetric measurements were seen after 2 weeks of CDT. The FAB score change showed a moderate correlation with circumference change and volumetric change (r = -0.41) but a very weak correlation with TUGT change (r = -0.1). The FAB Scale showed acceptable responsiveness in detecting treatment effects in patients with unilateral secondary lymphedema after breast cancer treatment.

RESUMEN

PURPOSE: The aim of this study was to evaluate the reliability and validity of the Turkish version of the FAB(FAB-T) scale in the older Turkish adults. METHODS: The reliability and validity of the scale was tested on 200 community-dwelling older adults. FAB-T scale was scored by different physiotherapists on different days to evaluate inter-rater and intrarater reliability. The Berg Balance Scale (BBS) was used for the evaluation of convergent validity, and the content validity of the FAB-T scale was investigated. RESULTS: The FAB-T scale showed very high inter- and intra-rater reliability. For inter-rater agreement, on the individual test items and total score ICC values were 0.92 (95 %CI; 0.90-0.94) and 0.96 (95% CI; 0.95-0.97) respectively. The intra-rater agreement, on the individual test items and total score ICC values were 0.93 (95 %CI; 0.91- 0.95) and 0.96 (95% CI; 0.95- 0.97) respectively. There was a good agreement between the FAB-T and BBS scales. A high correlation was found between the BBS and FAB-T scales [rho = 0.70 (%95 CI; 0.62-0.76)] indicating good convergent validity. Considering the content validity of the FAB-T scale, no floor (floor score: 0%) or ceiling (ceiling score: 6.5%) effect was detected. CONCLUSION: The FAB-T scale was successfully translated from the original English version (FAB) and demonstrated strong psychometric features. It was found that the FAB-T scale has very high inter-rater and intra-rater reliability. Considering the convergent validity, the scale has high correlation with the BBS. The FAB-T has no floor and ceiling effect.

RESUMEN

[Purpose] The purpose of this study was to investigate and compare the predictive properties of Berg Balance Scale and Fullerton Advanced Balance Scales, in a group of independently-functioning community dwelling older adults. [Subjects and Methods] Ninety-seven community-dwelling older adults (male=39, female=58) who were capable of walking independently on assessment were included in this study. A binary logistic regression analysis of the Berg Balance Scale and Fullerton Advanced Balance Scale scores was used to investigate a predictive model for fall risk. A receiver operating characteristic analysis was conducted for each, to determine the cut-off for optimal levels of sensitivity and specificity. [Results] The overall prediction success rate was 89.7%; the total Berg Balance Scale and Fullerton Advanced Balance Scale scores were significant in predicting fall risk. Receiver operating characteristic analysis determined that a cut-off score of 40 out of 56 on the Berg Balance Scale produced the highest sensitivity (0.82) and specificity (0.67), and a cut-off score of 22 out of 40 on the Fullerton Advanced Balance Scale produced the highest sensitivity (0.85) and specificity (0.65) in predicting faller status. [Conclusion] The Berg Balance Scale and Fullerton Advanced Balance Scales can predict fall risk, when used for independently-functioning community-dwelling older adults.

RESUMEN

Objective To compare 6 sub-function scale differences of frontal lobe function rating scale or a Frontal Assessment Battery(FAB)among patients with two subtypes of vascular cognitive impairment(VCI) to provide clues for the distinctive intervention and disease prevention and control of patients with two subtypes.Methods Totally 220 non-dementia vascular cognitive impairment (NDVCI)patients and 68 patients with vascular dementia(VaD)with final diagnosis were selected.The overall function and six sub-function scores were tested by FAB.Analyzing the score difference and probing a progress tendency from NDVCI to VaD were performed.Results The scores of frontal lobe function rating scale were higher in NDVCI(14.0 ± 2.8)than in VaD (9.5±2.0) patients with significant difference(t =29.92,P =0.00).The scales of frontal lobe function rating score of conceptualization ability (t =6.24,P =0.00),intelligence flexibility (t =7.00,P =0.00),antiinterference ability(t =7.21,P =0.00) and attention suppression(t =5.32,P =0.00) were lower in VaD group than in NDVCI group.The conceptualization weight capacity was significantly lower in VaD group than in NDVCI group(0.04 versus 0.32).Conclusions During a transitive process from NDVCI to VaD,it is important to focus on the mutation and deterioration of conceptualization capacity.

RESUMEN

INTRODUCTION: The relationship between freezing of gait (FOG) and postural instability in Parkinson's disease (PD) is unclear. We analyzed the impact of FOG on postural control. METHODS: 31 PD patients with FOG (PD+FOG), 27 PD patients without FOG (PD-FOG) and 22 healthy control (HC) were assessed in the ON state. Postural control was measured with the Fullerton Advanced Balance (FAB) scale and with center of pressure (COP) analysis during quiet stance and maximal voluntary forward/backward leaning. RESULTS: The groups were balanced concerning age, disease duration and disease severity. PD+FOG performed significantly worse in the FAB scale (21.8 ± 5.8) compared to PD-FOG (25.6 ± 5.0) and HC (34.9 ± 2.4) (mean ± SD, p < 0.01). PD+FOG had impaired ability to voluntary lean forward, difficulties to stand on foam with eyes closed and reduced limits of stability compared to PD-FOG (p < 0.05). During quiet stance the average anterior-posterior COP position was significantly displaced towards posterior in PD+FOG in comparison to PD-FOG and HC (p < 0.05). The COP position correlated with severity of FOG (p < 0.01). PD+FOG and PD-FOG did not differ in average COP sway excursion, sway velocity, sway regularity and postural control asymmetry. CONCLUSIONS: PD+FOG have reduced postural control compared to PD-FOG and HC. Our results show a relationship between the anterior-posterior COP position during quiet stance and FOG. The COP shift towards posterior in PD+FOG leads to a restricted precondition to generate forward progression during gait initiation. This may contribute to the occurrence of FOG or might be a compensatory strategy to avoid forward falls.
