The aim of this study was to estimate the immediate effects of plantar vibration, applied to the more affected foot, on balance impairment in patients post-stroke. This pretest-posttest clinical study included 18 patients (13 men) poststroke; mean age 56.0±8.9 years (range, 41–71 years). One session of 5-min vibratory stimuli (frequency, 100 Hz) was applied to the plantar region of the more affected foot of all participants. The plantar vibration significantly improved the Timed UP and Go test (P=0.03, Cohen d=0.15), ankle plantar flexor muscle spasticity (P=0.008), and ankle passive range of motion (P<0.001, Cohen d=0.74). The posturography measures and Functional Reach Test did not improve significantly (P>0.05). Vibration stimuli applied to the plantar region of the more affected foot had significant effects on spasticity, ankle passive range of motion and dynamic balance as evaluated by the Timed Up and Go test in patients poststroke. There was no effect on static balance performance. Based on the results, the focal vibratory stimuli applied directly to the plantar region of the more affected foot may be recommended to improve the functional mobility and dynamic balance in patients with stroke.

Objective To re-explore the responsiveness of the Persian version of Multiple Sclerosis Walking Scale-12 (MSWS-12p) to physiotherapy intervention and determine the minimally clinically important change (MCIC). This study followed a prospective cohort design. Patients with MS (PwMS) underwent physiotherapy treatment for 10 sessions. The outcome measures were the MSWS-12p and Timed 25-Foot Walk test (T25-FW). Data was collected before and after ten sessions of physiotherapy. The effect sizes and the area under receiver operating characteristics curve (AUC) and MCIC were calculated. Results Thirty PwMS (16 female, mean age 43.07 years) participated in the study. The effect sizes for MSWS-12p were moderate (0.52, 0.64). The change scores of MSWS-12p showed excellent correlation with the dichotomized smallest detectable change (SDC) criterion (Eta coefficient test = 0.84). There was no correlation between the MSWS-12p total change scores and the T25-FW (r = − 0.14, p = 0.45). The AUC was perfect and the MCIC for the MSWS-12p was calculated 10.0 points. The MSWS-12p is responsive and demonstrates changes after physiotherapy. Changes > 10.0 points on MSWS-12p total score should be considered as true improvement after physiotherapy.
