A clinical trial evaluating the efficacy of yoga on the perception of stress and back pain.

An English randomized controlled trial of Hartfiel and colleagues, published in the journal Occupational Medicine http://occmed.oxfordjournals.org/ in 2012, comparing 8-week efficacy of yoga on perceived stress, back pain and psychological well-being. The results show that a yoga program on workplace participants reduced perceived stress, back pain and improve psychological well-being.

The Study Rationale

Stress and back pain are the two main reasons for absenteeism at work. These health disorders “cost” 17 billion pounds to the British company each year. In 2011, management of Health and Safety Executive estimated at 10.8 million, the number of working days lost due stress at work and 7.6 million days due to musculoskeletal disorders for which 40% were accompanied by back pain. NPI workplace including stress management programs and cognitive behavioral therapies have proven effective in reducing stress and back pain. Physical exercise, in turn, proved effective in reducing low back pain and improve physical and mental health of workers.

Yoga includes physical exercises, breathing exercises, relaxation techniques and meditation. Yoga is known to increase mindfulness and the link between body and mind. Recent clinical trials suggest efficacy of yoga to reduce stress and pain. But no randomized controlled trial has evaluated its effectiveness at the place of individuals working to relieve back pain.

The Question

A dru yoga program it reduces workplace the perceived stress and back pain workers?

The Protocol

The randomized controlled Hartfiel and colleagues evaluated the effectiveness of a dru yoga program on workplace on perceived stress and back pain workers. The study covers 59 employees aged between 25 and 64 years. Participants with a score on the scale of functional and psychological complaints from two or more to stress and / or back pain were included in the study. The workers were randomly placed either in the yoga group or the control group.

The measures were perceived stress (PSS survey), back pain (RMDQ the questionnaire) and mental well-being (PANAS-X questionnaire). Participants assessed early intervention and late response to two months.

The tested Non-Pharmacological Intervention (NPI)

The NPI is called “dru yoga.” This is a particular form of yoga for therapeutic purposes and accessible to most people. This form of yoga is characterized by achieving graceful movements, by a consciously directed breathing and relaxation techniques. The program lasts 2 months with a group session per week. Each session lasts 50 minutes and includes four phases: (1) activation exercises, (2) energy release exercises blocked using movements (3) postures and exercises (4) relaxation exercises. It is recommended that participants perform two additional 20-minute sessions per week at home. A DVD is provided for these individual sessions.

Main Results

Before the intervention, 10 participants of the yoga group and 8 participants in the control group reported back pain against respectively 4 and 13 participants at the end of intervention.
