Lumbar Spinal Stenosis
Conditions
Brief summary
The purpose of this research is to compare two different approaches for treating patients with lumbar spinal stenosis: electric dry needling and thrust manipulation versus impairment-based manual therapy, stretching, strengthening and electrothermal modalities. Physical therapists commonly use all of these techniques to treat lumbar spinal stenosis. This study is attempting to find out if one treatment strategy is more effective than the other.
Detailed description
Patients with lumbar spinal stenosis will be randomized to receive 1-2 treatment sessions per week for 6 weeks (up to 12 sessions total) of either: (1) electric dry needling and thrust manipulation or (2) impairment-based manual therapy, stretching, strengthening and electrothermal modalities
Interventions
OTHERelectric dry needling, manipulation
HVLA thrust manipulation to lumbar spine. Dry needling to lumbar/sacral paraspinal muscles and gluteus medium/minimus muscles. Treatment may include dry needling of the piriformis muscle, quadrates lumborum muscle and perineurial needling of sciatic/tibial nerve. Up to 12 treatment sessions over 6 weeks.
OTHERconventional physical therapy
Impairment-based manual therapy, stretching, strengthening and electrothermal modalities targeting the lumbar/sacral spine and hips. Up to 12 treatment sessions over 6 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in low back pain (NPRS) (Rating Score) | baseline, 2-weeks, 6-weeks and 3-months | Baseline score must exceed 2/10 to be included in the study. |
| Change in Oswestry Disability Index | baseline, 2-weeks, 6-weeks and 3-months | The Oswestry Disability Index (ODI) includes 10 questions, each worth 0-5 points with maximum score of 50 points possible. The greater the score, the worse the disability. Baseline score must exceed 10/50 points to be included in the study. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Roland Morris Disability Index | baseline, 2-weeks, 6-weeks and 3-months | The Roland Morris Disability Index (RMDI) is measured on a 0-24 scale. Greater scores indicate increased disability. |
| Change in Global Rating of Change Score | 2-weeks, 6-weeks and 3-months | — |
| Change in Medication Intake (Frequency of medication intake in last week) | baseline, 3 months | — |
