Effect of Segmental Muscle Vibration on Upper Limb Function in Post Stroke Patients

The aim of this study is to observe and to compare effects of segmental vibration on flexors versus extensor muscle groups on upper limb function in post-stroke patients. This study will be helpful in finding out that either low frequency segmental vibration on flexors muscle group is better in improving upper limb function or low frequency segmental vibration on extensor muscle group is more beneficent in improving upper limb function.

About this study

Stroke is the leading cause of long-term disability and is often associated with persistent involvement of upper limbs.Several disturbances are the manifestation of UL impairments after stroke (i.e., muscle weakness, changes in muscle tone, joint disturbances, impaired motor control) . Muscular weakness and spasticity are most commonly observed in post stroke patients. There are many strategies are developed to improve functional status and to reduce spasticity pattern in post stroke patients. Among the different approaches to improve motor functions in post stroke patients, vibration therapy gives strong stimulatory effects in post paretic limb. Segmental muscle vibration (SMV) is a fairly new technique that has been used to improve motor function and inhibit spasticity in the hemiplegic upper extremity of patients following a stroke. In SMV, a vibratory stimulus is applied to a specific muscle tendon using a mechanical device unit.The aim of this study is to observe and to compare effects of segmental vibration on flexors versus extensor muscle groups on upper limb function in post-stroke patients. This study will be helpful in finding out that either low frequency segmental vibration on flexors muscle group is better in improving upper limb function or low frequency segmental vibration on extensor muscle group is more beneficent in improving upper limb function.

Treatment and study plan

segmental muscle vibration

Device

Segmental muscle vibration will delivered over the target muscles by means of vibrator with general physical therapy session

Other names: general physical therapy session

Primary outcomes

  1. Wolf Motor Functional Test

    Time frame: 10 to 15 minutes

    WMFT is valid and reliable on assessing upper extremities motor function of stroke patients. The WFMT is a tool with high interrater reliability, internal consistency, test-retest reliability and adequate stability.

  2. Modified Ashworth Scale

    Time frame: 4 to 5 minutes

    This scale measures resistance during passive soft-tissue stretching and is used as a simple measure of spasticity

  3. Fugl Meyer Assessment

    Time frame: 10 minutes

    Fugl Meyer Assessment

  4. Manual Muscle Testing

    Time frame: 8 to 10 minutes

    to check muscle strength

  5. • Brunnstrom Stages of Stroke Recovery • Brunnstrom Stages of Stroke Recovery Brunnstrom Stages of Stroke Recovery

    Time frame: 5 to 10 minutes

    to check the stages of improvemnet
