Clinical evaluation of a myofeedback-based teletreatment service applied in the workplace: a randomized controlled trial

Abstract

We evaluated the clinical effects of a myofeedback-based teletreatment service in terms of pain, pain-related disability and work ability. We also investigated the time investment/savings of this treatment with respect to conventional care. Sixty-five women with neck and shoulder pain at work participated in the study. Thirty-three took part in the teletreatment and 32 participated in a control group which continued with conventional care. Questionnaires were completed before the start of the intervention (baseline) and at initial follow-up (T0) and 3 months (T3) after the intervention ended. A general linear model analysis for repeated measurements showed an improvement in terms of pain and work ability for both groups taken together, with no differences between them. Non-parametric tests showed an intervention effect in pain-related disability for both groups together and no differences between them when tested at baseline, T0 and T3. The time saved in relation to conventional care was mainly from reduced travel time, which was 41 min per teleconsultation. The teletreatment service allowed employees to take part in muscle relaxation training while performing their regular work. The clinical evaluation showed that the treatment was on par with conventional care, but without the effort and time loss associated with regular visits to the clinic. We conclude that the myofeedback-based teletreatment service has potential for addressing neck and shoulder symptoms at the workplace.
