About

Hemiparesis is a condition characterized by weakness or the inability to move on one side of the body, making it difficult to perform everyday activities like eating or dressing (Iswatun et al., 2022). It is a common after-effect of stroke that causes weakness on one side of the body, limiting movement and affecting all basic activities such as dressing, eating, and walking. Hemiparesis can also be a sign of a stroke, and the side of the body weakened by hemiparesis could be ipsilateral (the same side as the brain injury) or contralateral (the opposite side of the brain injury) (Obman, 2020).

The symptoms of hemiparesis include: Weakness, Difficulty walking, Loss of balance, Muscle fatigue, Difficulty with coordination, Inability to grasp objects. Additionally, a person with hemiparesis may experience trouble maintaining balance, standing, or walking, as well as a tingling or numbing sensation on the weak side (Brandstaedter & Lindenbaum, 2023). Difficulty grabbing things, moving with precision, and lack of coordination can also be present. Hemiparesis is a one-sided muscle weakness that can affect all or most of the anatomical segments on one side of the body (Dantes et al., 2020).

Constraint-Induced Movement Therapy (MCIMT) with combination of Motor Relearning Program (MRP) has significant effects on stroke rehabilitation. CIMT is considered to achieve its beneficial effects through mechanisms such as overcoming learned nonuse and use-dependent neural plasticity. However, in case of Bobath there in no such evidence. Therefore more studies are needed to evaluate the effects of CIMT with MRP and Bobath only in both acute and chronic post-stroke populations. Therefore, the aim of this research is to focus on rehabilitation of hemiparetic arm. This present study compared the effects of CIMT with MRP versus Bobath to Augment Functional Motor Recovery of Chronic Hemiparetic Arm.

Full description

To determine the comparative effects of constraint-induced movement therapy (CIMT) with motor relearning program (MRP) and Bobath therapy to augment functional motor recovery of chronic hemiparetic arm.

Study Design: Randomized Control Trial

Study Setting: The data was collected from the University of Lahore Teaching Hospital and Sehat Medical Complex , Lahore.

Study Duration: 9 months after the approval of synopsis.

Sampling technique: It was purposive sampling technique.

Sample size: The sample size was 56 (28 in each group ) in each group calculated through software

Group A (CIMT +MRP)

Group B (Bobath)

Screening: Patients were screened to meet inclusion criteria. The consent form was taken from patients then patients will be randomly allocated into two groups ( 28 in each group).

Randomization: Patients fulfilling the inclusion criteria were randomly divided into experimental and control groups using the computer software.

Blinding: The study was single-blinded. The assessor was unaware of the treatment given to both groups.

Assessment: Data was collected at baseline, third and then at the end of the six week. Baseline assessments was conducted before the intervention. Post-intervention assessments were conducted immediately after the intervention. Statistical analysis included descriptive statistics, normality test and analysis of variance to compare the outcomes between the two groups.

Treatment Plan:

Both CIMT with MRP and Bobath both groups received 6 weeks of therapy, 5 days per week, for 3 hours/day per session. Each session was divided into phases: warm-up, active intervention, cool-down.Therapists monitored participant progress and adjust difficulty levels as needed. Home exercise programs was provided for daily practice.

Ethical Considerations: This study has received ethical approval from the Institutional Review Board (IRB). Informed consent was obtained from all participants.

Data Analysis: Statistical software was used to analyze the data, with appropriate tests employed based on data normality to compare outcomes between groups.

Enrollment: 64 patients

Sex: All

Ages: 50 to 65 years old

Volunteers: No Healthy Volunteers

Constraint-Induced Movement Therapy (CIMT) with the Motor Relearning Program (MRP)

Experimental group

Description:

Intensive training sessions focusing on the paretic arm. The unaffected arm is constrained using a mitt or sling to encourage using the affected limb. Emphasis on repetitive practice of functional tasks to enhance motor learning and skill acquisition. MRP Components: Standard physiotherapy sessions emphasizing strength, range of motion, and coordination. Task-specific training and neuromuscular re-education to improve motor function. Therapy sessions are conducted five days a week for six weeks, with additional home exercise programs to reinforce skills.

Treatment:

Behavioral: Constraint-Induced Movement Therapy (CIMT) With Motor Relearning Program (MRP)

Bobath therapy

Experimental group

Description:

Bobath therapy is a task-oriented approach focusing on balance, postural control, and the facilitation of normal movement patterns to improve motor skills and independence. It aims to inhibit abnormal muscle tone and promote efficient motor strategies.

Treatment:

Behavioral: Bobath Therapy
