Digital therapeutics-based lumbar core exercise for patients with low back pain: A prospective exploratory pilot study

초록

Objective: This study aimed to implement a digital therapeutics-based approach based on motion detection technology and analyze the clinical results for patients with chronic low back pain (LBP).Methods: A prospective, single-arm clinical trial was conducted with 22 patients who performed mobile app-based sitting core twist exercise for 12 weeks. Clinical outcomes were assessed using the visual analog scale (VAS) for LBP, Oswestry Disability Index-Korean version (K-ODI), and EuroQol-5 dimension 5-level version (EQ-5D-5L) every 4 weeks after the initiation of treatment. Laboratory tests for factors associated with muscle metabolism, plain X-ray for evaluating sagittal balance, and magnetic resonance imaging for calculating cross-sectional area (CSA) of back muscles were performed at pretreatment and 12 weeks post-treatment.Results: The study population included 20 female patients with an average age of 45.77 +/- 15.45 years. The clinical outcomes gradually improved throughout the study period in the VAS for LBP (from 6.05 +/- 2.27 to 2.86 +/- 1.86), K-ODI (from 16.18 +/- 6.19 to 8.64 +/- 5.58), and EQ-5D-5L (from 11.09 +/- 3.24 to 7.23 +/- 3.89) (p < 0.001, respectively). The laboratory test results did not show significant changes. Pelvic incidence (from 53.99 +/- 9.70 degrees to 50.80 +/- 9.20 degrees, p = 0.002) and the mismatch between pelvic incidence and lumbar lordosis (from 8.97 +/- .67 degrees to 5.28 +/- 8.57 degrees, p = 0.027) decreased significantly. Additionally, CSA of erector spinae and total back muscles increased by 5.20% (p < 0.001) and 3.08% (p = 0.013), respectively.Conclusions: The results of this study suggest that the efficacy of digital therapy-based lumbar core exercise for LBP is favorable. However, further large-scale randomized controlled studies are necessary.
