Static and dynamic balance deficiencies in chronic low back pain

Area of Science:

• Biomechanics
• Neurology
• Musculoskeletal Health

Background:

• Previous research indicates static balance deficits in individuals with Low Back Pain (LBP).
• Understanding balance impairments is crucial for managing LBP and improving patient outcomes.

Purpose of the Study:

• To compare static and dynamic balance abilities between individuals with Chronic Low Back Pain (CLBP) and healthy controls.
• To investigate the utility of the Star Excursion Balance Test (SEBT) and Center of Pressure (CoP) excursion in differentiating CLBP patients.

Main Methods:

• A comparative study involving 17 CLBP patients and 16 healthy controls, matched for age, BMI, and gender.
• Balance assessment included the Star Excursion Balance Test (SEBT) and a static 1-leg stance, both performed on a force plate to measure target sway (TS) or Center of Pressure (CoP) excursion.
• Logistic regression analysis was used to classify subjects based on SEBT and TS scores.

Main Results:

• CLBP patients demonstrated significantly poorer performance on the SEBT and exhibited greater static and dynamic TS values.
• Age and Body Mass Index (BMI) were found to significantly influence SEBT performance.
• The combined SEBT and TS scores correctly classified 85% of the subjects.

Conclusions:

• Both static and dynamic balance assessments provide valuable information for identifying CLBP.
• Dynamic balance measures, particularly those derived from the SEBT, appear more instrumental in the detection of CLBP.
