When Limping Comes from the Spine, Not the Leg
Intervertebral Disc Disease, or IVDD, occurs when an intervertebral disc degenerates, protrudes, or extrudes into the vertebral canal, potentially irritating or compressing nearby spinal nerves or the spinal cord. Depending on the affected region and severity, patients may develop spinal pain, altered gait, weakness, reluctance to climb stairs, difficulty standing, or reduced mobility.
This patient was presented for limping and difficulty walking and climbing stairs. Although the signs initially appeared to involve the limbs, neurologic and orthopedic assessment raised concern for a spinal origin. Radiographic findings showed changes involving the L5–L6 region that were considered compatible with suspected intervertebral disc disease.
The patient was managed conservatively using prescribed medications, activity restriction, and Class IV laser therapy as an adjunctive rehabilitation modality. Therapeutic laser delivers controlled light energy to targeted tissues and may help reduce pain and inflammation while supporting local circulation and tissue recovery. It does not mechanically remove disc material, so treatment selection depends on the patient’s neurologic status, severity of pain, and response to medical management.
After several treatment sessions, the patient demonstrated marked improvement in gait, stair-climbing ability, and overall mobility. Limping resolved, and functional movement was restored during follow-up assessment.
This case highlights that limping is not always caused by a problem within the leg itself. Spinal disorders may produce pain, weakness, or altered movement that can resemble an orthopedic condition. Early evaluation helps determine whether conservative treatment is appropriate or whether advanced imaging and surgical referral should be considered.
Clinical Presentation: Difficulty walking, limping, and reluctance to climb stairs
Diagnostic Assessment: Neurologic and orthopedic examination with radiographic evaluation of the lumbar spine
Working Diagnosis: Suspected L5–L6 intervertebral disc disease
Management: Medication, controlled activity, and adjunctive Class IV laser therapy
Outcome: Marked improvement with resolution of limping and restoration of functional mobility
