Focal Muscle Vibration on Upper Limb Function in Subacute Post-stroke Patients
Keywords
Abstract
Description
Evidence strongly suggest that a period of pure sensory stimulation can affect motor corticoids activity excitability.
In 2019 segmental muscle vibration(SMV) used to improve upper extremity functional ability post stroke and concluded that patients in both groups improved significantly after treatment in Barthel index (BI), elbow Range of Motion (ROM) and elbow muscle strength. However muscle tone in elbow joint of hemiplegic upper extremity improved significantly after only in the experimental group. They suggested that with routine physiotherapy with extended exposure SMV will results in significant reduced spasticity and better improved Activities Of Daily Livings (ADLs).
In 2019 a work done with SMV to improve gate performance in patients with foot drop after chronic stroke. Results of this study revealed moderate improvement in mean gate speed, normal side swing velocity, bilateral stride length and normal-side toe off in experimental group. Further studies needed to evaluate the optimal and minimum SMV dosage.
Another study conducted in 2019 to see Results show that processing speed, inhibitory control and attention improved following SMV. But working memory between groups and also not show a association between executive functions course and fall risk, so they suggest further work to examine effects of vibration therapy on executive functions.
In 2014 another therapist highlight the potential use of SMV to modulate electromyographic (EMG) for reaching movement in chronic stroke patients but needs to be confirmed by larger control perspective trials of SMV.
In 2019 combined work done with repetitive focal muscle vibration with physiotherapy to improve the motor function even in very acute phase of stroke and finds it a valid complementary non pharmacological therapy In 2019 another study suggest that Whole Body Vibration (WBV) and Upper and Lower Cycle (ULC) effective upper for upper extremity motor function and grip strength in sub-acute stroke.
In 2019 a study reported the risk factors (vibration injury to hands vascular components, intermediate blanching neurological components and lower back pain for drivers of work machines) and benefits (improvement in bone health and neuromuscular function). So is a room for research to design a balanced WBV protocol.
A study in 2018 did a meta-analysis and compare the effects of WBV in stroke patients and concludes that it is a safe therapeutic method for improving symptoms.

Active Comparator: Conventional Treatment Conventional Treatment includes exercises limbs | Other: Conventional Treatment These individuals will receive the conventional intervention including the routine rehabilitation therapy like active and passive ROMs, stretching, strengthening of upper limb, balance improvement exercises. Time duration is of 40 minute 2 times per week. |
Experimental: Focal Muscle Vibration (120Hz) Each session will span 40 minutes plus 10 of Focal Muscle vibration for each muscle at a frequency of 120 Hz.
Conventional Treatment | Other: Focal Muscle Vibration (120Hz) These individuals will receive conventional therapy along with Focal Muscle Vibration applied to the hyper toned muscles (Bicep Brachialis and Extensor Carpi Radialis). Evaluation at baseline and after the end session (Total 24 session). i.e. 3 sessions/week for 8 weeks. |
