Objective: The aim of this study was to compare trunk muscle endurance, flexibility, and quality of life in adolescent idiopathic scoliosis (AIS) patients with healthy peers following fusion (PIF) surgery with posterior instrumentation.
Materials and Methods: Twenty patients aged between 10-18 years who underwent PIF surgery in last 1-3 years and 20 healthy peers were included. The lumbar range of motion (ROM), flexibility, trunk extensor, flexor muscle endurance, and the quality of life (QoL) were assessed in both groups.
Results: Lumbar flexion (AIS: 73°, Control: 84°), extension (AIS: 24°, Control: 37°), right lateral flexion (AIS: 24°, Control: 46°), left lateral flexion (AIS: 25°, Control: 45°), right rotation (AIS: 29°, Control: 45°) left rotation ROM (AIS: 31°, Control: 52°), flexibility in sit and reach (AIS: -18±9.82 cm, Control: -3±8.52 cm), in lateral bending (AIS: 12±3.65 cm, Control: 21±3.64 cm), trunk extension (AIS: 30s, Control: 61s), flexion muscle endurance (AIS: 19s, Control: 66s) comprised the physical component score on the SF-12 scale, which showed significantly better results in the healthy group (p<0.001). In addition, there was a strong correlation between trunk muscle endurance and extension ROM (r=0.721), right rotation ROM (r=0.718), moderate correlation with trunk flexion ROM (r=0.414), left lateral flexion ROM (r=0.581), and there was a strong correlation between trunk extensor muscle endurance and QoL in AIS patients (p<0.001).
Conclusion: The results showed that there was lower quality of life, range of motion, flexibility, and muscle endurance in AIS patients as compared to healthy individuals. Additionally, muscle endurance was related to the quality of life and mobility in AIS patients after surgery.
