EarLy Exercise in blunt Chest wall Trauma: A multi-centre, parallel randomised controlled trial (ELECT2 Trial).

INTRODUCTION

The aim of this trial was to investigate the impact of early thoracic and shoulder girdle exercises on chronic pain and Health-Related Quality of Life in patients with blunt chest wall trauma, when compared to normal care.

METHODS

A multi-centre, parallel, randomised controlled trial, in which adult patients presenting to hospital with blunt chest wall trauma were allocated to either control or intervention group. The intervention was an exercise programme consisting of four simple thoracic and shoulder girdle exercises, completed for one week. Outcomes measures included prevalence and severity of chronic pain using the Brief Pain Inventory, health-related quality of life using EQ-5D-5 L, and cost effectiveness, measured at initial presentation and three months post-injury.

RESULTS

360 participants were recruited. Participants' mean age was 63.6 years (standard deviation (SD): 17.9 years) and 213 (59.8 %) were men. After loss-to-follow-up, the survey response rate at three months was 73.0 % (251/344 participants). The primary analysis, for chronic pain prevalence at three months post-injury, found no statistically significant differences between intervention and control groups, with lower rates in the control (intervention: 35/126 (27.8 %), control: 20/117 (17.1 %); adjusted odds ratio 1.862; 95 % CI: 0.892 to 3.893, p = 0.098). There were no statistically significant differences between intervention and control groups for pain severity at three months post-injury, (intervention mean (SD): 2.15 (2.49), control: 1.81 (2.10); adjusted difference 0.196, 95 % CI:0.340 to 0.731; p = 0.473); or Health-Related Quality of Life (intervention mean (SD): 0.715 (0.291), control: 0.704 (0.265); adjusted difference: 0.030; 95 % CI:0.033 to 0.094; p = 0.350). The health economic analysis found the intervention was associated with higher costs compared to normal care.

CONCLUSION

The results of this trial did not support a 'one-size fits all' simple, early exercise programme for patients with blunt chest wall trauma. Future research should consider the impact of a personalised exercise programme, commenced by the patient at least one week post-injury.
