Conclusions : Age-related differences support the impact of stroke-related sarcopenia as a contributor to hemiparetic muscle dysfunction .
Abstract Background : Despite extensive study of the impact of stroke on muscle and functional performance , questions remain regarding the extent to which changes are due to the neurological injury vs. age-related loss of morphology and force production .
Objectives : To synthesize available evidence describing post-stroke changes in lower extremity muscle size and strength compared to healthy adults .
Effects of Whole-Body Vibration on Muscle Architecture, Muscle Strength, and Balance in Stroke Patients: A Randomized Controlled Trial
Objective The aim of the present study was to analyze the effects of whole-body vibration on lower limb muscle architecture , muscle strength , and balance in stroke patients during a period of 3 mos . Design The inclusion criteria were having had ischemic or hemorrhagic stroke at least 6 mos before the study and a National Institutes of Health Stroke Scale score of greater than 1 and less than 20 . The patients were r and omly divided into two groups : an  experimental group ( n = 11 , six men and five women ; age , 62.4 ± 10.7 yrs ; height , 1.64 ± 0.07 m ; mass , 69.4 ± 12.9 kg ) and a sham group ( n = 9 , five men and four women ; age , 64.4 ± 7.6 yrs ; height , 1.62 ± 0.07 m ; mass , 75.0 ± 15.8 kg ) . The experimental group received a whole-body vibration treatment , with an increase in frequency , sets , and time per set during 17 sessions . The sham group performed the same exercises as that of 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 . Results There were no significant differences between the groups on the primary outcomes of lower limb muscle architecture , muscle strength , and balance . Conclusions It seems 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
