Brief summary
Hatha Yoga is a traditional system of exercises, used in India for the relief of painful condition since centuries and gaining more and more interest in Europe and the US. While studies have demonstrated benefits of Hatha Yoga for patients with chronic low back pain, no studies regarding chronic neck pain are available until now. The purpose of this study is to determine if Hatha Yoga can ameliorate chronic neck pain and related restrictions.
Detailed description
Hatha Yoga is a traditional system of exercises, used in India for the relief of painful condition since centuries and gaining more and more interest in Europe and the US. The efficacy of Hatha Yoga for relieving chronic low back pain has been repeatedly demonstrated in clinical trials, while there are no studies in the literature regarding chronic neck pain. The aim of this study is to investigate, whether a 9 weeks-course of Hatha Yoga reduces subjective pain ratings and disability in patients suffering from chronic neck pain. Furthermore, as neck pain patients have been shown to suffer from impaired sensory processing and proprioception, along with restricted range of motion, the study aims to test if Hatha Yoga can improve these variables. Therefore, tests regarding cervicocephalic proprioception, active range of motion and the processing of mechanical, vibration and pain stimuli will be included. 58 patients with chronic nonspecific neck pain will be randomized to either Hatha Yoga group or control group, receiving information regarding exercises for chronic neck pain. The control group will be offered to take part in a Yoga class after the end of the study.
Interventions
BEHAVIORALHatha Yoga
* 9 weeks of Hatha Yoga, designed for treating chronic neck pain, as a group intervention. * One class of 90 minutes per week, 10 minutes training at home each day.
BEHAVIORALInformation regarding exercises and behaviour
* 9 weeks of exercises practiced at home. * Patients receive detailed information regarding appropriate exercises and behaviour for chronic neck pain patients.

| Active range of motion | Week 10 | 6 movement directions (flexion, extension, rotation right/left, lateral flexion right/left) |
| Pain related to motion | Week 10 | 100mm visual analog scale for 6 movement directions (flexion, extension, rotation right/left, lateral flexion right/left) according to: Irnich D, Behrens N, Molzen H, König A, Gleditsch J, Krauss M, Natalis M, Senn E, Beyer A, Schöps P.

| Pressure pain threshold | Week 10 | Pressure pain threshold measured at two individual points at the neck: (1) at the point of maximal pain and (2) in the adjacent region, one to two cm outside the painful area. Furthermore, it is measured bilaterally at levator scapulae muscle, semispinalis capitis muscle and trapezius muscle and at both hands, serving as control sites. Measurement procedure according to the protocol of QST. Reference: Rolke R et al..

| Cervicocephalic kinesthetic sensibility | Week 10 | The ability to exactly relocate the head on the trunk in a self-chosen neutral forward-position after an active movement. according to: Revel M, Andre-Deshays C, Minguet M. Cervicocephalic kinesthetic sensibility in patients with cervical pain. Arch Phys Med Rehabil. 1991;72:288-91. |
| SF-36 | Week 10 | The SF-36 is a short-form health survey consisting of 8 scales (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health) measuring functional health and well-being as well as a physical a and mental health component scores.

| Pain diary | From Week 1 to Week 10 | 100mm visual analog scale for rating neck pain intensity each day |
