Objective: To evaluate the feasibility and possible effects of whole-body vibration (WBV) training on muscle strength and gait performance in people with late effects of polio.
Design: A case-controlled pilot study with assessments before and after training.
Setting: A university hospital rehabilitation department.
Participants: People (N=5; 3 men, 2 women; mean age, 64 +/- 6.7y; range, 55-71y) with clinically and electrophysiologically verified late effects of polio.
Interventions: All participants underwent 10 sessions of supervised WBV training (standing with knees flexed 40 degrees-55 degrees up to 60 seconds per repetition and 10 repetitions per session twice weekly for 5 weeks).
Main Outcome Measures: Isokinetic and isometric knee muscle strength (dynamometer), and gait performance (Timed Up & Go, Comfortable Gait Speed, Fast Gait Speed, and six-minute walk tests).
Results: All participants completed the 5 weeks of WBV training, with no discernible discomfort. No significant changes in knee muscle strength or gait performance were found after the WBV training period.
Conclusions: This pilot study did not show any significant improvements in knee muscle strength and gait performance following a standard protocol of WBV training. Thus, the results do not lend support to WBV training for people with late effects of polio.
