Rehabilitation Following Lumbar Disc Surgery

Not Applicable

Completed

• Conditions: Lumbar Disc Herniation; Radiculopathy

• Registration Number: NCT00894972
• Lead Sponsor: University of Utah

Brief Summary

The proposed study will be a randomized clinical trial designed to determine the most effective physical therapy program for individuals who have undergone lumbar discectomy surgery. The study will compare two different post-operative physical therapy programs (general strengthening or general + specific strengthening). Both groups will begin treatment 2 weeks post-surgery. Subjects in both groups will receive weekly treatment sessions for 8 weeks with a treatment program emphasizing exercises shown to activate the large trunk muscles without imposing potentially harmful compression or shear forces. The general + specific strengthening group will also receive exercises shown to isolate activation of the deep trunk muscles, in particular the multifidus, with training augmented by the use of diagnostic ultrasound biofeedback. Patient assessments will be conducted pre- and post-surgery, as well as 10 (post-treatment) and 26 weeks after surgery.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 60

Inclusion Criteria

• 18-60 years old
• Diagnosis of LDH based on imaging (MRI or CT scan) of the lumbar spine with concurring clinical examination findings (based on the judgment of the attending neurosurgeon)

Exclusion Criteria

• Prior surgery to the lumbar spine
• Spondylolytic or degenerative spondylolisthesis present on pre-surgical imaging
• Unable to speak and understand English
• Peri- or post-operative complication (infection, nerve injury, dural tear, vascular injury, etc.) that would limit or delay the ability to participate in post-operative rehabilitation.
• Multi-level surgery or the use of instrumentation during surgery (i.e., lumbar fusion)
