Comparison of manual therapy and exercise therapy for postural hyperkyphosis: A randomized clinical trial

Abstract

Objective: To compare the efficacy of a manual therapy and an exercise therapy program in improving postural hyperkyphosis among young adults.

Methods: Forty-six women between the ages of 18 to 30 years with thoracic kyphosis diagnosed by flexicurve ruler were randomly assigned to either an exercise therapy or a manual therapy group. The exercise therapy program focused on stretching and strengthening exercises in 15 sessions over 5 weeks. The manual therapy group received 15 sessions of manual techniques including massage, mobilization, muscle energy and myofascial release. Kyphosis angle and back extensor muscle strength were measured with a motion analysis system and a dynamometer at the baseline and after treatment. The data were analyzed with paired and independent t-tests.

Results: After treatment, the angle of thoracic kyphosis was smaller and back extensor muscle strength was significantly greater in both the exercise and manual therapy groups (p < 0.001). We found no significant differences between groups in the changes in kyphosis angle or muscle strength after treatment (p > 0.05).

Conclusion: Manual therapy was as effective as exercise therapy in reducing kyphosis angle and increasing back extensor muscle strength in young women with postural hyperkyphosis.
