[The preliminary clinical application of a smart orthosis personalized management system for the treatment of patients with adolescent idiopathic scoliosis].

Objective: To develop a smart orthosis personalized management system for the treatment of patients with adolescent idiopathic scoliosis (AIS) and to evaluate the feasibility and efficiency through clinical preliminary applications.
Methods: The smart orthosis personalized management system consists of a wireless force monitor, a WeChat Mini Program, a cloud-based storage system, and a website backstage management system. Twenty-two patients with AIS who underwent orthosis treatment and met the selection criteria between March 2020 and December 2020 were enrolled. The follow-up time was 4 months. The parameters used to evaluate patients' compliance were as follows (back and lumbar): baseline force value, measured force value, force compliance (measured force value/baseline force value×100%), measured wearing time (wearing time of force value was more than 0 N), and time compliance (measured wearing time/prescribed wearing time×100%), in which the prescribed wearing time was 23 hours/day. The baseline force values were measured at initiation, while the measured force value, measured wearing time, force compliance, and time compliance were measured during follow-up. The differences of these parameters between back and lumbar, and the differences among these parameters at 1, 2, 3, and 4 months after orthosis wearing were analyzed.
Results: The average measured force value of 22 patients (back and lumbar) was (0.83±0.34) N, the average force compliance was 68.5%±17.9%, the average measured wearing time was (15.4±1.7) hours, and the average time compliance was 66.9%±7.7%. The baseline force value and measured force value of back were significantly higher than those of lumbar ( P <0.05); the measured wearing time, force compliance, and time compliance between back and lumbar showed no significant difference ( P >0.05). The measured force value, measured wearing time, force compliance, and time compliance at 1 month after wearing were significantly lower than those at 2, 3, and 4 months after orthosis wearing ( P <0.05), no significant difference was found among 2, 3, and 4 months after orthosis wearing ( P >0.05). At different time points after wearing, the measured force value of back were significantly higher than that of lumbar ( P <0.05), while there was no significant difference between back and lumbar on the other parameters ( P >0.05).
Conclusion: The smart orthosis personalized management system has high feasibility to treat AIS, and can improve the compliance of such patients with orthosis wearing.
