Brief Summary

Coronary artery bypass grafting (CABG) is one of the common procedure used in coronary artery disease patients which has significant impact on cardiopulmonary and musculoskeletal systems. In the past, phase 1 rehabilitation after procedure focus on cardiopulmonary system. Lower limb rehabilitation is also important part as it influence the cardiac function. Several studies work on post-CABG patients to improve cardiopulmonary fitness but there is less number of data on calf muscles rehabilitation in post-CABG patients. So this study aims to increase the calf muscle extensibility using post-isometric relaxation technique and static stretching.

Conditions

Coronary Artery Bypass

Outcome Measures

Primary Outcomes (1)

• length of calf muscles

  The length of soleus and gastrocnemius will be measured by using goniometer. The participant will be in supine position with knee extended and knee flexed to 45 degrees for gastrocnemius and soleus muscle respectively. The axis of the goniometer will be placed on lateral malleolus, moving arm parallel to the fifth metatarsal and stationary arm parallel to lower leg. The patient is asked to perform dorsiflexion and the length is measured by recording the angle of the goniometer.

  Immediate after treatment

Secondary Outcomes (1)

• Lower limb temperature

  Immediate after treatment

Study Arms (3)

Basic Cardiac Rehabilitation protocol

ACTIVE COMPARATOR

ankle pumps and leg slides, 2 sets of 10 repetitions of each exercise. Walk for 10 minutes.

Procedure: Basic Cardiac Rehabilitation Protocol

post-isometric relaxation technique with basic cardiac protocol

EXPERIMENTAL

ankle pumps and leg slides, 2 sets of 10 repetitions of each exercise. Walk for 10 minutes. Post-isometric relaxation technique: contraction time 10 second using 20% of strength with 15 second rest period in between contractions + 4 repetitions.

Procedure: post-isometric relaxation technique; Procedure: Basic Cardiac Rehabilitation Protocol

static stretching with basic cardiac protocol

EXPERIMENTAL

Ankle pumps and leg slides, 2 sets of 10 repetitions of each exercise. Walk for 10 minutes. Static stretching: 5 repetitions with 15 sec hold time of stretch.

Procedure: Static stretching; Procedure: Basic Cardiac Rehabilitation Protocol

Interventions

post-isometric relaxation technique PROCEDURE

Post-isometric relaxation technique will be performed by asking the patient to contract his calf muscles using 20% of his strength. Maintain the contraction for 10 second with 15 second of rest time between each contractions. A total of 4 contractions will be performed.

Static stretching PROCEDURE

Static stretching will be performed by asking patient to perform dorsiflexion till the point of discomfort. The patient will hold the stretch for 15 second and 5 repetitions will be performed.
