An 18-month follow-up study on the effect of a neuromuscular stabilization technique on Cobb's angle in adolescent idiopathic scoliosis: A single-blind, age-matched controlled trial.

BACKGROUND

The benefits of spinal realignment and stabilization in scoliosis need to be examined.

OBJECTIVE

We aimed to investigate the long-term effect of a neuromuscular stabilization technique (NST) on Cobb's angle in patients with adolescent idiopathic scoliosis.

METHODS

Twenty females recruited from two hospitals participated in this study. On the basis of convenience of location, participants were allocated to either the experimental group (EG) that underwent the NST, or the control group (CG) that received education for a home exercise program. The NST for the EG was performed for an average of 30 min per session, three times a week for six months, and consisted of spinal realignment and stabilization. Then, 12- and 18-month measurements for long-term follow-ups were conducted for the EG. The outcome measure was Cobb's angle.

RESULTS

Between-group comparison revealed a statistically significant difference at post-test (t=-3.26, p< 0.01) but not pre-test (t=-1.36, p= 0.19). Participants of the EG (-6.20 ± 2.49∘) showed greater differences between pre- and post-test scores compared to participants of the CG (-1.40 ± 0.52∘) (p< 0.05). Within-group comparisons showed a significant difference in both groups (p< 0.05). In the EG, Cobb's angle significantly changed across the follow-up sessions (p< 0.05), indicating more improvements by the 12-month (8.50 ± 4.03∘) and 18-month (6.60 ± 3.89∘) follow-ups.

CONCLUSION

This study shows that the NST may be a beneficial option to correct spinal alignments in patients with adolescent idiopathic scoliosis.
