The effects of whole body vibration combined computerized postural control training on the lower extremity muscle activity and cerebral cortex activity in stroke patients.

The paper does not state which outcome was primary. The sample was small, with only 10 patients in each group. The outcomes were muscle activity and brain-wave relative band power, not walking, balance, or function. No blinding is described, so participants and assessors may have known group assignment. No dropout or missing-data handling is described. All patients could walk more than 10 m independently, so results may not apply to non-ambulatory stroke patients. The intervention was whole body vibration combined with computerized postural control training, so the study does not show what whole body vibration alone would do. The comparison groups also received computerized postural control training, so the added effect is relative to that training, not to usual care. The study lasted 8 weeks, so longer-term effects are unknown.

Sehan University funded the research in 2017. The authors declared no conflicts of interest.

Do not conclude that whole body vibration improves walking or daily function. The study measured vastus lateralis percent reference voluntary contraction and Cz beta-SMR relative band power, not functional outcomes.
