Effect of Pain Reduction and Functional Improvements Following a Noninvasive Biomechanical Intervention for Gait Rehabilitation on Healthcare Claims: An Observational Study.

Background

Musculoskeletal conditions substantially impact public health in the United States, affecting approximately 128 million adults and resulting in over $600 billion in annual socioeconomic costs. Low back pain and knee osteoarthritis are the most prevalent musculoskeletal disorders, with projections suggesting their incidence will increase markedly due to aging populations and rising obesity rates.

Objective

The purpose of this study was to evaluate healthcare claims utilization (HCRU), clinical outcomes, and patient satisfaction for individuals with knee and back pain treated with a home-based, biomechanical intervention that aims to provide precision medicine for patients with musculoskeletal conditions.

Methods

A retrospective analysis of claims data was conducted on 616 patients with knee and back pain who were treated with a noninvasive, home-based, biomechanical intervention (AposHealth) from October 2020 to October 2023. Eligibility was determined based on specific diagnostic criteria. The controls were 3576 patients with knee and back pain who were receiving the standard of care. HCRU, pain levels, functional disability, and patient satisfaction were captured.

Results

Significant reductions in HCRU were noted, with significantly lower rates of minor and major surgeries compared with control groups. The economic analysis suggested substantial cost savings of approximately $9 million over 20 months, suggesting an 80% reduction in costs in those treated with the biomechanical intervention compared with controls. Pain levels decreased significantly by 32.5% and 57% at 3 and 6 months posttreatment for back pain, respectively. Patients with knee pain reported a significant decrease of 39% and 35% at 3 and 6 months, respectively. Discussion: The examined biomechanical intervention led to a significant reduction in pain and improvement in function, which presumably is a driving factor for a meaningful reduction in HCRU and potential cost savings.

Conclusions

There is an urgent need for innovative strategies that alleviate the burden of musculoskeletal disorders on the healthcare system. The results of this study add to the evidence about the clinical effectiveness and cost-savings of this intervention in patients with knee and back pain, using real-world data.
