Various studies have shown the efficacy of conventional isometric,
Pilates and yoga exercises. However, data on the effects and comparison of these
specific exercises on the cervical muscle morphology are insufficient or lacking.
OBJECTIVE: To investigate the effects of different exercise treatments on neck
muscles in patients with chronic neck pain. DESIGN: A randomized study. METHODS:
Fifty-six patients with chronic neck pain were randomized into 3 groups as
follows: Pilates group (n = 20), yoga group (n = 18) and isometric group (n =
18). Demographics and background information were recorded. The thickness and
cross-sectional area of neck muscles were evaluated by ultrasound imaging.
Cervical motions were measured with a goniometer. Pain severity was evaluated
with the McGill Pain Scale, disability with the Neck Disability Index, quality of
life with the Nottingham Health Profile, and emotional status with the Beck
Depression Inventory. In addition to a conventional physio-therapy programme, 15
sessions of physical therapy, including hot pack, ultrasound, and transcutaneous
electrical nerve stimulation (TENS), were provided to all patients. All groups
performed the exercises for 6 weeks. The aforementioned assessments were
performed before and 6 weeks after the treatment. RESULTS: Although pain,
disability, depression and quality of life improved similarly within all groups
(all p < 0.05), muscle thickness values as regards the semispinalis capitis were
increased only in the Pilates group (p = 0.022). STUDY LIMITATIONS: The lack of
complex (progressive resistive) exercise treatment protocols, short treatment
duration and partial supervision. CONCLUSION:
All 3 types of exercise had
favourable effects on pain and functional scores, but no differences were found
among the groups, except for the Pilates group, in which the semispinalis capitis
muscle increased in thickness.
