Effects of whole body vibration on functional capacity and respiratory functions in individuals with stroke: A randomized controlled study

BACKGROUND: Management of respiratory-related functional problems using sensory rehabilitation strategies has been poorly researched in patients with stroke. OBJECTIVE: This study aimed to investigate whether whole body vibration (WBV) training has an effect on functional capacity and respiratory functions in patients with stroke. METHODS: In the randomized-controlled study, 28 participants were randomized into two groups: one receiving Neurodevelopmental Treatment (NDT; n = 13) and one receiving both NDT and WBV (NDT + WBV; n = 15). The primary outcome measures were 6-Minute Walking Test (6MWT) and Pulmonary Function Test which evaluate functional and respiratory capacity. Secondary outcome included the chest circumference measurement to evaluate the thoracic expansion ability. RESULTS: Both groups showed positive significant changes in walking distance and maximum oxygen consumption volume (VO(2)max), inspiratory capacity, vital capacity and chest circumference measurement scores (p < 0.05). While the NDT+WBV group showed a significantly greater increase inwalking distance and VO(2)max levels than the NDT group (p < 0.05), there were no significant group differences in respiratory function flow and volume parameters, and chest circumference measurement. CONCLUSION: The addition of WBV training to the treatment program has some incremental benefits on increasing functional capacity and thoracic expansion, and rehabilitating respiratory dysfunction.
