A prospective study on the clinical efficacy and patients' acceptance of SpineCor and rigid spinal orthoses in treatment of AIS


Although the clinical effectiveness of rigid spinal orthosis to AIS has been demonstrated, the patient's acceptance is always a concern. Poor compliance may affect treatment outcomes as well as a patient's quality of life. The flexible spinal orthosis, SpineCor is a relatively new design for tackling those inevitable drawbacks inherent in the rigid spinal orthosis. However, there are few studies to compare the SpineCor system with the rigid spinal orthosis regarding their treatment efficacy and patients' acceptance.


The objective of this study is to compare treatment efficacy and patient acceptance for the SpineCor system with the rigid spinal orthosis.


Forty-three subjects with moderate AIS were randomly assigned to the SpineCor group (S group, n = 22) and the rigid orthosis group (R group, n = 21). In this prospective study, their survival rate in the first 45 months of intervention was studied. The subjects' acceptance to the orthoses was evaluated by a purpose-designed questionnaire which was administered in the 3rd, 9th and 18th months of intervention.


The results of this study showed that there were 68% of the subjects in the S group and 95% of the subjects in the R group did not show curve progression > 5°. A significant difference (p = 0.046, by Fisher exact test) in failure rate between the 2 subject groups was found. In the patient survey, the 2 subject groups had similar responses to the questionnaire.


This study demonstrated that the rigid spinal orthosis was more effective than the SpineCor in curve control while the patients' acceptances to these two orthotic designs were comparable.
