Effects of Imaginary Resisted Exercise Versus Physical Resisted Exercise on Hand Grip Strength in Stroke Patients

Not Applicable

Completed

Interventions: Other: Imaginary Resistance Exercises
Other: Physical Resisted Exercises

Brief Summary: The goal of our study is to make a comparison between the effectiveness of physical resistance exercise and imaginary resistance exercise in improving handgrip strength, dexterity, and eye-hand coordination among stroke patients.

Detailed Description: A Randomized Control Trial study will be conducted in which patients with stroke will be allocated to Group A that will receive imaginary resistance exercises and patients in group B will receive physical resistance exercises.

The intervention will be applied (3 days /week) for 12 weeks, which consists of 5 different types of resistance using 5 different resistive objects, each will have 15 repetitions. Each session includes handgrip exercises with physical resistance exercises for one group and imaginary resistance exercises using Virtual Reality Box for another group. As for improving dexterity and eye-hand coordination, the Purdue pegboard test and finger-to-nose test will be used respectively in both groups with 15-15 repetitions.

Arm && Interventions

Group	Intervention	Description
Imaginary Resisted Exercises	Imaginary Resistance Exercises	Handgrip exercises with the imagination of resistance in hand by getting feedback in VR Box will be given as an intervention. Stretching will be given at the beginning and the end of each session. This will include imaginary resistance exercises for handgrip by using Virtual Reality Box. Five types of different resistances will be imagined by patients by watching their own videos in VR box, which will be recorded on day one to make them familiar with the resistive objects and the resistance experienced from them by asking patients to perform 15-15 repetitions of each object. Every imaginary resistance exercise will have 15 repetitions. After performing exercises, the participants will ask to perform Finger-to-Nose Test and Purdue Pegboard Test.
Physical Resisted Exercises	Physical Resisted Exercises	Handgrip exercises with physical resistance in hand will be given as an intervention. Stretching will be given at the beginning and the end of the session. 5 different types of resistances will be given to patients for making themselves familiarize themselves with the type of resistance applied by each object, that they will experience in further sessions, by asking them to perform 15-15 repetitions of each object. Every physical resistance exercise will have 15 repetitions. After performing exercises, the participants will ask to perform Finger-to-Nose Test and Purdue Pegboard Test.

Primary Outcome Measures

Name	Time	Method
Goniometer	12th Week	Goniometer has been the most widely used tool for measuring joint range of motion. To ensure reliable measurement, standardized, specific positions and landmarks are used to measure each joint movement.
Hydraulic Hand Dynamometer	12th Week	It is an isometric instrument that can provide the most stable results during repetitive gripping exercises. This instrument has been reported to have high validity and reliability. This is considered to be a "Gold Standard" instrument, and many researchers have used the Jamar as a standard to validate other instruments.
Purdue Peg Board Test	12th Week	It is a functional assessment tool to screen for hand dexterity. It was designed to assess fine motor hand function using three common objects, pegs, washers, and collars, to be inserted on a pegboard. With its long history and wide usage, its reliability in healthy subjects is well established because it employs tasks that resemble activities of daily living. It is economical and easy to administer
