Yoga-based intervention for carpal tunnel syndrome: a randomized trial.
BACKGROUND
Carpal tunnel syndrome is a common complication of repetitive activities and causes significant morbidity.


OBJECTIVE
To determine the effectiveness of a yoga-based regimen for relieving symptoms of carpal tunnel syndrome.


METHODS
Randomized, single-blind, controlled trial.


METHODS
A geriatric center and an industrial site in 1994-1995.


METHODS
Forty-two employed or retired individuals with carpal tunnel syndrome (median age, 52 years; range, 24-77 years).


METHODS
Subjects assigned to the yoga group received a yoga-based intervention consisting of 11 yoga postures designed for strengthening, stretching, and balancing each joint in the upper body along with relaxation given twice weekly for 8 weeks. Patients in the control group were offered a wrist splint to supplement their current treatment.


METHODS
Changes from baseline to 8 weeks in grip strength, pain intensity, sleep disturbance, Phalen sign, and Tinel sign, and in median nerve motor and sensory conduction time.


RESULTS
Subjects in the yoga groups had significant improvement in grip strength (increased from 162 to 187 mm Hg; P = .009) and pain reduction (decreased from 5.0 to 2.9 mm; P = .02), but changes in grip strength and pain were not significant for control subjects. The yoga group had significantly more improvement in Phalen sign (12 improved vs 2 in control group; P = .008), but no significant differences were found in sleep disturbance, Tinel sign, and median nerve motor and sensory conduction time.


CONCLUSIONS
In this preliminary study, a yoga-based regimen was more effective than wrist splinting or no treatment in relieving some symptoms and signs of carpal tunnel syndrome.
