Effects of Combined Segmental Vibrator and Neuromuscular Electrical Stimulation in Subacute Stroke

Stroke is leading cause of death and disability worldwide, resulting in significant functional limitations and disabilities experienced by stroke survivors, particularly in the upper limb. There is a need for more effective interventions targeting upper limb sensory motor impairments. The aim of this study is to study combined effect of segmental vibrator and neuromuscular electrical stimulation for flexor and extensor muscle groups on upper limb function in sub-acute stroke.

This study will be a randomized clinical trial and will be conducted in physiotherapy department of Allama Iqbal Memorial Teaching Hospital Sialkot, National Bone and Joint Hospital and Bashir Hospital Sialkot. Forty stroke patients will be recruited through non-probability convenience sampling technique and will be randomly divided in two equal groups Group A and group B through lottery method. Group A will receive high frequency segmental vibration on flexor and extensor muscle groups while group B will receive neuromuscular electrical stimulation along with high frequency segmental vibration(100Hz) on flexor and extensor muscle groups Data will be collected from patients of sub-acute stroke by using screening tool MoCA(for cognition) and assessment tools Fugl-Meyer Assessment Scale(for upper limb function), Wolf Motor Functional Test(for motor function), Modified Ashworth Scale(for spasticity) , Barthel Index(for ADLs), Maximal Hand Grip Strength(for manual dexterity), Maximal Pinch Grip(for manual dexterity), Nottingham Sensory Assessment(for somatosensory function). An informed consent will be taken. Outcome measures will be assessed at baseline, at 4th week and at 8th week. Follow up will be performed at 12th week. Data analysis will be done by SPSS version 28.0.
