Medical Laser – $20 per visit, per body part

Our specially-trained clinicians offer state-of-the-art deep-penetrating laser therapy. Treatment is typically given in a series, as it creates a change at the cellular level as damaged cells absorb the light’s energy. These cellular changes in mitochondrial activity and cell permeability can result in quicker healing times and decreased pain. These safe, pain-free, and quick treatments are effective for a wide array of orthopaedic conditions, including arthritis, degenerative disc disease, muscle strains, muscle spasm, sciatic pain, tendonitis and other overuse injuries. (Not typically covered by insurance).

Available by appointment at JOI Rehab San Marco Spine Center, South Spine Center, and Beaches locations only.
