Examining the Effectiveness of a Post-operative Rehabilitation Program Emphasizing Restoration of Multifidus Muscle Function for Individuals Undergoing Lumbar Discectomy: a Randomized Clinical Trial


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.


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)

- Appropriate surgical candidate based on the opinion of the attending spine surgeon,
and scheduled for single-level lumbar discectomy (open or micro-discectomy).

- Able to attend weekly treatment sessions.

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)
