Key result
Benson relaxation plus arm ergometry improves post-CABG quality of life by ~42 points.
Why the study?
While Benson’s Relaxation Technique and arm ergometry have demonstrated individual benefits in cardiac rehabilitation, their combined effect on pulmonary function, pain, and quality of life after CABG remains underexplored.
Does combining Benson's Relaxation Technique and arm ergometry improve pulmonary function, pain intensity, and quality of life in patients after coronary artery bypass grafting?
Does combining Benson's Relaxation Technique and arm ergometry improve pulmonary function, pain intensity, and quality of life in patients after coronary artery bypass grafting?
A 7-day combined rehabilitation program of Benson's Relaxation Technique and arm ergometry significantly improved inspiratory/expiratory volumes, reduced pain intensity, and enhanced quality of life in patients recovering from CABG.
May support combined BRT and AE post-CABG rehab; leaves open confirmation in randomized trials.
Background. Coronary artery bypass grafting (CABG) is often followed by impaired pulmonary function, pain, and reduced quality of life. While Benson’s Relaxation Technique (BRT) and arm ergometry (AE) have demonstrated individual benefits in cardiac rehabilitation, their combined effect remains underexplored.Aim. This study aimed to evaluate the effectiveness of combining BRT and AE in improving pulmonary function, reducing pain, and enhancing quality of life in patients after CABG.Materials and methods. A single-group pretest–posttest study was conducted in a tertiary care intensive care unit with 60 patients after CABG, aged 45-65 years. Over seven days, patients underwent twice-daily AE training following the FITT principle and daily sessions of BRT. Primary outcomes included inspiratory and expiratory volumes measured using a three-ball incentive spirometer, pain intensity assessed using the Numeric Rating Scale, and health-related quality of life assessed using the SF-36 questionnaire.Results. Inspiratory volume increased from 427.70±283.12 cc to 1073.68±149.43 cc (p<0.001), while expiratory volume increased from 473.60±346.70 cc to 894.73±144.40 cc (p<0.001). Pain intensity decreased from 8.82±0.89 to 3.83±1.11 (p<0.001), while SF-36 scores increased from 19.14±6.81 % to 60.69±5.80 % (p<0.001).Conclusion. The combined application of BRT and AE significantly improved pulmonary function, reduced pain intensity, and enhanced quality of life during early recovery after CABG. These findings support a combined rehabilitation approach to improve comprehensive recovery in this population.

Bandral et al. (2026) studied Post-coronary artery bypass grafting (CABG) (n=60). Benson's Relaxation Technique combined with arm ergometry vs. Pretest baseline (single-group pretest-posttest) was evaluated on Inspiratory and expiratory volumes, pain intensity (Numeric Rating Scale), and health-related quality of life (SF-36) (p=<0.001). Combining Benson's Relaxation Technique and arm ergometry after CABG increased inspiratory volume (427.7 to 1073.7 cc), reduced pain (8.82 to 3.83), and improved SF-36 (19.1% to 60.7%; all p<0.001).
