Interventional Study of Effects on Spine Height With Two Unloading Positions
- Conditions
- Low Back Pain
- Interventions
- Other: aquatic vertical suspension.Other: land-based supine flexion
- Registration Number
- NCT01048749
- Lead Sponsor
- Texas Tech University Health Sciences Center
- Brief Summary
The purpose of this study is to test a physical therapy intervention for reducing pain in the low back and into the legs. With individuals over the age of 40 years, this pain may be associated to changes in back height from aging of the cushions between the back bones. When pain is caused from this, completion of different positions and rest periods have been shown to help reduce the pain, at least temporarily. This study will compare two such positions; 1)floating in deep warm water with weights attached to the ankles, to take the load off of the spine, 2)lying on their back with hip and knees flexed to a 90 degree angle. The height of each person will be measured before and after completion of each intervention using a specially designed measuring tool.
Experimental hypothesis:
1. Subjects with low back and leg pain suggestive of nerve root compression syndrome will experience increase in spinal height when completing aquatic vertical suspension and/or land-based supine flexion.
2. Subjects with low back and leg pain suggestive of nerve root compression syndrome will experience greater increase in height, greater reduction of pain intensity and location when completing underwater vertical suspension as compared to supine land based flexion.
- Detailed Description
Spinal height is affected throughout life from many different physiological changes and mechanical stresses, but a large portion is thought to occur primarily from intervertebral disc degeneration with resultant reduction in overall spinal height. The use of specific postures and rest periods to increase the overall spinal height has been suggested through various stadiometric research studies. This overall spinal height change can be used as a treatment tool for management of symptoms of chronic low back pain and signs of nerve root compression.
The purpose of the study is to investigate the effect of aquatic vertical suspension on spinal height, symptom location and pain intensity compared to a more commonly used land based supine flexion position.
The study will be conducted at one outpatient physical therapy clinic with subjects recruited from the local community.
A single blinded True Experimental Repeated Measure cross over design will be utilized.
Spine height will be measured using a commercially available stadiometer. Spinal height measurements will be completed after loaded walking, supine land based flexion positioning and after aquatic vertical hang.

Group Intervention Description aquatic vertical supsension aquatic vertical suspension. Spinal height measurement using a stadiometer following aquatic vertical suspension land-based supine flexion condition land-based supine flexion Spine height will be measured with a stadiometer following completion of the supine land-based flexion position.
- Primary Outcome Measures
Name Time Method Differences of change of spinal height following aquatic vertical suspension compared to lumbar supine flexion positioning. Spine height is measured prior to and after each intervention and then statistical comparisons completed.
- Secondary Outcome Measures
Name Time Method Differences in pain intensity and location following aquatic vertical suspension compared to supine land-based flexion position. Pain intensity and location measurements are taken prior to and after completion of each intervention
