Effects of whole-body vibration on muscle architecture, muscle strength, and balance in stroke: A randomized controlled trial

But why didn't they check for sensation and proprioception? Do they not know how to run a clinical trial? Does this negate this study?:

Abstract: Study analyzed the effects of whole-body vibration on lower-limb muscle architecture, muscle strength, and balance in stroke patients over a period of 3 months. Twenty patients were randomly divided into two groups: an experimental group and a sham group. The experimental group received a whole-body vibration treatment, with an increase in frequency, sets, and time per set during 17 physical therapy sessions. The sham group performed the same exercises as the experimental group but was not exposed to vibration. Outcome variables included the muscle architecture (the rectus femoris, the vastus lateralis, and the medial gastrocnemius), the maximal isometric voluntary contraction of the knee extensors, and the Berg Balance Scale. There were no significant differences between the groups on the primary outcomes of lower-limb muscle architecture, muscle strength, and balance. Results suggest that whole-body vibration exercise does not augment the increase in neuromuscular performance and lower-limb muscle architecture induced by isometric exercise alone in stroke patients.
