The study evaluated the efficacy of orthopedic footwear in treating lumbar intervertebral disc herniation with spinal manipulation in 44 patients. Surface electromyography tests showed less asymmetry in lumbar muscle activity with orthopedic footwear. Patients receiving spinal manipulation with orthopedic footwear had a shorter healing time of 20.36 days compared to 28.14 days for patients receiving spinal manipulation only. Orthopedic footwear improved lumbar muscle symmetry and balance, creating favorable conditions for spinal manipulation to shorten the healing time.
