BACKGROUND: Progressive resistance exercise (PRE) can have a positive effect in individuals with Parkinson's disease (PD). However, the effect of PRE may vary with the clinical subtype of PD. To date, no study has assessed the effects of PRE in the different subtypes of PD. AIM: The aim of the present study was to assess the effects of PRE in PD patients with akinesia and rigidity (AR-subtype). DESIGN: A randomized controlled trial was conducted. SETTING: Outpatients clinics of the Bierzo Parkinson Association (Ponferrada, Spain) and the Asturias Parkinson Association (Oviedo, Spain). POPULATION: Twenty-eight patients with AR-subtype PD were randomized into an Experimental Group (EG, N.=13) and Control Group (CG, N.=15). METHODS: Static posturography (Centre of Pressure -CoP- parameters), gait (the Ten-Meter Walk Test [TMWT]), freezing of gait (the Freezing of Gait Questionnaire [FOG-Q]), the motor portion of the Movement Disorders Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and patient-perceived quality of life (the 39-item Parkinson's disease Questionnaire [PDQ39]), were assessed at pre-test, post-test, and re-test. Ratings of perceived exertion (RPE) (Borg >6-20 Scale) were recorded at the end of each PRE training session. RESULTS: The EG displayed significant ameliorations in Length (CoP parameters) from pre- to post-test (P=0.048), in speed of fast rhythm walking (TMWT) from pre- to post-test (P=0.000), and from pre- to re-test (P=0.027), and in the PDQ39 Score from pre- to post-test (P=0.024). No significant differences were detected in Area or Speed (CoP parameters), speed of preferred rhythm walking (TMWT), FOG-Q scores, or the motor portion of the MDS-UPDRS scores. The EG reported a mean RPE of 9.95 (between "very light" and "fairly light") for the whole training program. CONCLUSIONS: These findings provide support for the use of PRE training in the rehabilitation of individuals with AR-subtype PD, as it can improve static posturography, gait, and quality of life. Furthermore, RPE scores showed that individuals with AR-subtype PD consider that PRE training require only light efforts. CLINICAL REHABILITATION IMPACT: The PRE training can be a helpful and fruitful rehabilitation tool for AR-subtype PD patients.

The main goal of the study was to assess the effects of slackline training on the postural control system and jump performance of athletes. Twenty-five female basketball players were randomized into 2 groups: control (N = 12) and experimental (N = 13). The latter experienced a 6-week supervised slackline training (3 sessions per week, 5-9 minutes per session). Participants underwent center of pressure (CoP) testing through three 10-second tasks (bipedal, left leg, and right leg support) over firm and compliant surfaces with eyes open. Several CoP parameters were assessed: length, area, length/area, speed, Ymean, Xmean, deltaY, deltaX, RMS (root-mean-squared amplitude of the CoP), RMSY, and RMSX. Surface electromyography recordings were obtained too. Participants were also tested on jump performance, provided perceived exertion (6-20 Borg scale) and local muscle perceived exertion. Center of pressure parameters significantly differed before and after training only in the experimental group and only on the compliant surface (left leg: length, area, speed, deltaY, and deltaX; right leg: length, speed, Ymean, deltaY, and RMSY). Surface electromyography recordings were comparable before and after training in both groups. Performance on a countermovement jump test significantly improved only in the experimental group (effect side was 3.21 and 1.36 [flight time and jump height, respectively], which is described as a large effect). Mechanical power of the legs, as measured through the 30-second maximal performance jump test, did not improve in either group. The slackline training was rated as "somewhat hard" with the quadriceps, soleus, and gastrocnemius being rated as the most engaged muscles. Data indicate that slacklining requires activation of the main lower limb muscles. On conclusion, slacklining may be a valid cross-training tool for female basketball players.
