Summary
Whole-body fatigue significantly impairs balance performance, increasing errors on the Balance Error Scoring System (BESS). This suggests BESS should not be administered immediately after strenuous activity or potential concussion.
Area of Science:
- Sports Medicine
- Neurology
- Biomechanics
Background:
- The Balance Error Scoring System (BESS) is a common tool for assessing postural stability, often used in concussion evaluations.
- Understanding the impact of physiological factors like fatigue on BESS performance is crucial for accurate assessment.
Purpose of the Study:
- To investigate the immediate effects of a whole-body fatigue protocol on BESS performance.
- To determine if fatigue protocols influence postural stability measurements.
Main Methods:
- A fatigue group underwent a 20-minute whole-body exertion protocol, while a control group rested.
- Both groups were assessed using the BESS before and immediately after the intervention.
- Ratings of perceived exertion were recorded using the Borg scale.
Main Results:
- The fatigue group showed a significant increase in BESS errors post-protocol, indicating diminished balance.
- The control group demonstrated a significant decrease in BESS errors.
- Significant differences in BESS errors and perceived exertion were observed between the groups post-intervention.
Conclusions:
- Immediate post-fatigue BESS performance is compromised, highlighting a reduction in balance ability.
- Clinicians should avoid administering the BESS test immediately following strenuous activity due to fatigue-induced balance deficits.
- Fatigue is a significant confounder in BESS assessments, particularly in sideline concussion evaluations.
