Advanced Services at Integrated Medical Group
Peripheral Neuropathy Program. Numbness, tingling, or burning in the hands and feet is one of the most frustrating conditions to live with — and one of the most under-treated. Our non-surgical program brings three therapies together: spinal decompression, sonic wave therapy (high-energy acoustic pulses that reach deep into tissue), and Class 4 laser. Together they’re designed to help reduce pain and support nerve health, circulation, and natural tissue repair. Individual results vary. This information is not medical advice.


Spinal Decompression. A gentle, non-surgical therapy that works to ease compression affecting the spine, discs, and nearby nerves. Spinal decompression may provide relief for conditions such as sciatica, herniated discs, and persistent neck or back discomfort without relying on medication or surgery.
Class 4 Laser Therapy. FDA-cleared deep-tissue laser that delivers therapeutic energy into painful or injured areas to help reduce pain and inflammation and support the body’s natural healing.
Sonic / Acoustic Wave Therapy. High-energy acoustic pulses that penetrate deep into soft tissue to help stimulate circulation and support repair — a key part of our neuropathy and soft-tissue programs.
Plantar Fasciitis Treatment. For stubborn heel pain, we combine laser, soft-tissue therapy, and biomechanical care to calm inflammation and get you moving comfortably again.
Peptide Therapy Options. Peptide-based wellness support some patients use as part of a plan for recovery, sleep, and overall wellness. Ask our team whether it’s right for you. Individual results vary. This information is not medical advice.
