Abstract
Context. Spinal cord injury (SCI) commonly results in paresis, which dramatically decreases walking function. Whole body vibration (WBV) stimulation may be able to increase lower extremity strength by activating the lower extremity muscles via afferent pathways and consequently improve neuromuscular function. Objective. This study assessed the effects of a single session of WBV on quadriceps strength in individuals with motor-incomplete SCI. Design. A double blinded randomized crossover design was used. Setting. The Miami Project to Cure Paralysis, University of Miami Miller School of Medicine. Participants. Subjects (age 50 ± 12.5 years) all had chronic SCI (>1 year) and were able to stand with minimal assistance for at least 45 seconds. Interventions. Each subject participated in a single session of WBV stimulation consisting of four 45-second bouts with 1-minute rest periods in between (frequency: 50Hz, amplitude: 2mm) and a single session of sham stimulation, with a 1-week washout period between sessions. Outcome measures. Maximal voluntary isometric quadriceps force was measured with a fixed dynamometer. A modified version of the Five-Time-Sit-To-Stand (FTSTS) test was used to assess functional quadriceps strength. Results. There was no statistically significant difference between the effects of a single session of WBV stimulation and sham stimulation on maximal voluntary isometric quadriceps force and functional quadriceps strength measured immediately after and 20 minutes after the interventions. Conclusion. Evidence from the present study does not provide support for the addition of WBV stimulation to rehabilitation programs to increase quadriceps strength in people with motor-incomplete SCI.
