Summary
Neither a lumbosacral orthosis (LSO) nor the abdominal drawing-in maneuver (ADIM) significantly improved postural control in balance tasks. These lumbar stabilization methods did not alter center of pressure parameters in the tested stances.
Area of Science:
- Biomechanics
- Motor Control
- Rehabilitation Science
Background:
- Lumbar stabilization techniques, including lumbosacral orthosis (LSO) and abdominal drawing-in maneuver (ADIM), are hypothesized to enhance lumbar stiffness and influence postural control.
- Understanding the specific effects of these interventions on balance is crucial for clinical application.
Purpose of the Study:
- To compare the effects of LSO and ADIM on postural control during semi-tandem and one-legged stance.
- To determine the reliability of postural control measurements under these conditions.
Main Methods:
- Twenty participants completed three conditions: no stabilization, LSO, and ADIM.
- Postural control was assessed using center of pressure (COP) parameters on a force platform during 30-second semi-tandem and one-legged stances.
- Measurements were repeated to assess reliability.
Main Results:
- LSO and ADIM interventions were comparable in their effects on postural control.
- Neither stabilization method significantly reduced COP values during the balance tasks.
- Measurement reliability was generally acceptable to excellent.
Conclusions:
- Lumbosacral orthosis (LSO) and abdominal drawing-in maneuver (ADIM) do not significantly alter postural control in one-legged or semi-tandem stances.
- These findings suggest that these methods may not be effective for improving postural control in these specific tasks from a rehabilitation perspective.
