An Experimental Study to Assess the Effectiveness of Jacobson Muscle Relaxation Therapy on Fatigue after Cardiac Surgery among Patients Undergone Cardiac Surgeries in Selected Hospital in Delhi

Abstract :
The study aimed to assess the severity of fatigue in patients who have undergone cardiac surgery and to investigate the effectiveness of Jacobson Progressive Muscle Relaxation Therapy (JPMRT) in reducing post-operative fatigue. Key objectives included evaluating fatigue severity and determining associations with demographic and clinical variables. Conducted as an experimental study with control and experimental groups, patients undergoing open-heart surgery at a quaternary care hospital in Southwest Delhi were selected for the research. A sample size of 125 was chosen using simple random sampling, complemented by a pilot study with 15 samples to check the validity and feasibility of the research. Data collection occurred on the 2nd post-operative day (pretest), followed by JPMRT intervention—15 minutes of progressive muscular relaxation performed 12 times over six days—in addition to standard nursing care. Posttest data were collected on the 7th post-operative day using the Checklist Individual Strength Scale, a 20-point tool measuring subjective fatigue, concentration, motivation, and activity. Statistical analysis confirmed a significant reduction in fatigue levels in the experimental group. To confirm whether the two groups were similar in the level of fatigue after the intervention, the Independent’s’ test was used. The obtained value was -10.419 which was less than the p value .00001 which is highly significant at p level (p < 0.05). This infers that the fatigue level was reduced in experimental group.
