Effectiveness of Three Manual Physical Therapy Techniques in a Subgroup of Patients With Low Back Pain
Effectiveness of Three Manual Physical Therapy Techniques in a Subgroup of Patients With Low Back Pain
Recently a clinical prediction rule (CPR) has been developed and validated that accurately
 identifies patients with low back pain that are likely to benefit from a lumbo-pelvic
 manipulation. The studies that developed and validated the rule used the identical
 manipulation procedure. However, recent evidence suggests that different manual therapy
 techniques may result in the same outcome.Purpose: The purpose of this study is to
 investigate the effectiveness of three different manual therapy techniques in a subgroup of
 patient with low back pain that satisfy the CPR.
Inclusion Criteria:

 1. Chief complaint of pain and/or numbness in the lumbar spine, buttock, and/or lower
 extremity

 2. Oswestry disability score of at least 25%

 3. Age greater than 18 years and less than 60 years

 4. At least four out of five of the following criteria:

 1. Duration of current episode < 16 days (judged from the patient's self-report)

 2. No symptoms extending distal to the knee (judged from the pain diagram)

 3. FABQ-W score <19

 4. At least one hip with >350 internal rotation range of motion (measured in prone)

 5. Stiffness in the lumbar spine (judged from segmental mobility testing)

 Exclusion Criteria:

 1. Red flags noted in the participant's general medical screening questionnaire (i.e.
 tumor, metabolic diseases, RA, osteoporosis, prolonged history of steroid use, etc.)

 2. Signs consistent with nerve root compression, this includes any one of the following:

 1. Reproduction of low back or leg pain with straight leg raise at less than 450

 2. Muscle weakness involving a major muscle group of the lower extremity

 3. Diminished lower extremity muscle stretch reflex (Quadriceps or Achilles tendon)

 4. Diminished or absent sensation to pinprick in any lower extremity dermatome

 3. Prior surgery to the lumbar spine or buttock

 4. Current pregnancy

 5. Past medical history of osteoporosis or spinal compression fracture

 6. Inability to comply with treatment schedule (weekly sessions for four weeks)
