- BACKGROUND: The posture control deficit is one important dysfunction in adolescent idiopathic scoliosis (AIS) patients, which is related to the development of the disease. However, it is not apparent whether AIS could affect static sitting posture control in late adolescence. OBJECTIVE: This study aims to compare static sitting posture control in idiopathic scoliosis freshmen with normal peers to reveal possible differences in posture stability between them during writing tasks. METHODS: In total, there were 10 AIS patients and 11 normal college students chosen for the writing task test. Data on the distribution of gluteal pressure during sitting were gathered. The comparison between these two groups was made using the independent sample t-test. RESULTS: The total excursion (TE) of the center of pressure (COP) of the AIS group considerably increased in comparison with the control group (CON) (p = 0.029). The AIS group's average COP velocity in the anteroposterior (AP) direction was significantly higher than the CON group (p = 0.048). The peak gluteal pressure on the right side was significantly higher in the AIS group than in the CON group (p = 0.039). The right gluteal contact area dynamic variation was significantly higher in the AIS group compared to the CON group (p = 0.025). CONCLUSIONS: AIS patients showed increased gluteal pressure and lower sitting posture stability during writing tasks.
