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

Management of respiratory-related functional problems using sensory rehabilitation strategies has been poorly researched in patients with stroke.This study aimed to investigate whether whole body vibration (WBV) training has an effect on functional capacity and respiratory functions in patients with stroke.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.Both groups showed positive significant changes in walking distance and maximum oxygen consumption volume (VO2max), inspiratory capacity, vital capacity and chest circumference measurement scores (p < 0.05). While the NDT +WBV group showed a significantly greater increase in walking distance and VO2max 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.The addition of WBV training to the treatment program has some incremental benefits on increasing functional capacity and thoracic expansion, and rehabilitating respiratory dysfunction.
