DNS vs Thoracic Stabilization Exercises in Thoracic Kyphosis

Summary

This randomized controlled trial aims to compare the effects of Dynamic Neuromuscular Stabilization (DNS) exercises and thoracic stabilization exercises on thoracic erector spinae muscle strength, thoracic kyphosis angle, pain and trunk stabilization in individuals with thoracic kyphosis. Thirty participants aged 18-40 years with thoracic kyphosis will be randomly allocated to a DNS exercise group or a thoracic stabilization exercise group. Surface EMG biofeedback will be used to assess thoracic erector spinae muscle activation, while pain, thoracic kyphosis angle and trunk endurance will be evaluated using validated clinical tests. The interventions will be applied for 6 weeks, and outcomes will be assessed before and after the intervention period.

Conditions

• Kyphosis

Interventions

BEHAVIORAL

Dynamic Neuromuscular Stabilization Exercises

Participants in the DNS group will perform Dynamic Neuromuscular Stabilization exercises based on developmental kinesiology. The program includes prone (4.5-month position), modified prone over a Swiss ball, quadruped (9-month position) and prone exercises on a Swiss ball with bilateral hand support. All exercises emphasize proper spinal alignment, diaphragmatic breathing and coordinated activation of the deep stabilizing muscles. Participants will complete two supervised sessions per week and perform home exercises twice daily (10 repetitions per exercise) for 6 weeks. An exercise diary will be used to monitor adherence.

BEHAVIORAL

Thoracic Stabilization Exercise

Participants in the thoracic stabilization group will perform a structured thoracic and scapular stabilization program including foam roller thoracic extension in supine, prone thoracic extension, child's pose with thoracic extension and scapular retraction exercises. The exercises are designed to improve thoracic mobility, strengthen the thoracic extensors and enhance postural alignment. Participants will complete two supervised sessions per week and perform home exercises twice daily (10 repetitions per exercise) for 6 weeks. Exercise adherence will be tracked with an exercise diary, and participants who miss the program for three consecutive days will be withdrawn from the study.
