Multiplanar Lumbopelvic Control in Patients With Low Back Pain

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to investigate whether combined assessment of lumbopelvic control during sagittal and frontal plane motion (using two common clinical observational assessments) discriminates between people with and without LBP than single plane assessment alone. It was hypothesized that the two tests used in combination (multiplanar) would perform better than each test used independently (single planar) in accurately discriminating patient cases from healthy controls.

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Patients with Low Back Pain<br>n= 19 Inclusion Criteria: Between the ages of 18 and 70 years Currently seeking, but not yet initiated, treatment from a health care professional (PT, MD, DO, DC) for a chief complaint of pain between the level of the twelfth thoracic vertebrae and the coccyx Able to transition between standing, sitting, supine, prone and sidelying independently Exclusion Criteria: Signs of neurological impairment including diminished myotatic reflex, sensory impairment or strength deficits in a myotomal pattern No previous spine or hip surgery Serious spinal or systemic pathology Pregnancy within previous 12 months Inability to understand and follow verbal instructions in English | |
| Healthy Controls<br>n= 19 Inclusion Criteria: Between the ages of 18 and 70 years No LBP episodes requiring clinical care by a health professional and/or greater than 3 days absence from work/school/recreation within the previous 5 years Able to transition between standing, sitting, supine, prone and sidelying independently Exclusion Criteria: No previous spine or hip surgery Serious spinal or systemic pathology Pregnancy within previous 12 months Inability to understand and follow verbal instructions in English | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Performance on Active Hip Abduction Test | Examiner scores movement pattern (ability to retain lumbopelvic neutral) during performance of active hip abduction in sidelying using an ordinal scale (0-3) with 0-1 considered a negative test and 2-3 considered a positive test. | Assessed on data collection day | 
| Performance on Active Straight Leg Raise Test | Participant self-rates degree of difficulty (0-5) to perform active straight leg raise in supine with any non-zero score considered a positive test result. | Assessed on data collection day |
