Effectiveness Study of Physical Therapy as an Adjunct to a Lumbar Therapeutic Selective Nerve Root Block

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00934284

Brief Summary:
The purpose of this study is to determine if participation in physical therapy in conjunction with a selective nerve root block in the lumbar spine is more effective than just receiving the injection alone for patients with low back and leg pain from a disk herniation (sciatica).

Condition or disease Intervention/treatment Phase
Sciatic Neuropathy Radiculopathy Intervertebral Disk Displacement Other: Lumbar injection Other: Rehabilitation following lumbar injection Phase 2

Detailed Description:
Recent reviews report moderate to strong evidence for short-term relief but limited evidence for long-term improvement. Anecdotal reports and case studies suggest good outcomes with various physical therapy interventions however well-designed research studies examining treatments in combination are lacking. The management of lumbar radicular pain often includes the combination of physical therapy and therapeutic selective nerve root blocks with the rationale that reducing inflammation and pain will permit greater participation in physical therapy. The effectiveness of this combination of treatment has not been studied and is the purpose of this pilot study.

Arm Intervention/treatment
Active Comparator: Injection only
Participants receive a therapeutic selective nerve root block and advice to return to normal activity as tolerated.
Other: Lumbar injection
Patients are instructed to resume normal activity as tolerated.

Experimental: Injection plus physical therapy
Participants are referred to physical therapy within one week of receiving a therapeutic selective nerve root block. Physical therapy consists of end-range movements in a directional preference and/or mechanical traction to reduce radicular symptoms.
Other: Rehabilitation following lumbar injection
Participants are referred to an average of four weeks of physical therapy after receiving a lumbar injection. Physical therapy designed to include end-range directional preference exercises and/or mechanical traction to reduce lower extremity symptoms and progress activity tolerance.

Primary Outcome Measures :
  1. Modified Oswestry Disability Index [ Time Frame: Baseline (pre-injection), 8 weeks (post-injection), 6 months post-injection ]

Secondary Outcome Measures :
  1. Global Rating of Change [ Time Frame: 8 weeks (post-injection) and 6 months (post-injection) ]
