Concussion history and brain disorder disabilities increase symptom scores in disabled athletes. Other concussion tests were not affected, highlighting the importance of baseline testing for at-risk athletes.
Area of Science:
- Sports Medicine
- Neurology
- Rehabilitation
Background:
- Concussion assessment in disabled athletes requires specialized tools.
- Understanding the impact of disability type and concussion history is crucial for accurate baseline evaluations.
Purpose of the Study:
- To determine if underlying disability and concussion history affect baseline concussion testing scores in veteran wheelchair athletes.
- To analyze scores from the modified Graded Symptoms Checklist (mGSC), Standardized Assessment of Concussion (SAC), and Wheelchair Error Scoring System (WESS).
Main Methods:
- Retrospective chart review of 81 veteran wheelchair sports athletes.
- Analysis of demographic data, qualifying disability, and scores from mGSC, SAC, and WESS.
- Comparison of scores based on concussion history and disability category.
Main Results:
- 43% of athletes reported a prior concussion.
- Higher mGSC scores were observed in athletes with a concussion history (P = 0.0378).
- Athletes with brain disorder disabilities (e.g., multiple sclerosis, cerebral vascular accident) had significantly higher mGSC scores compared to amputees and spinal cord disorder groups (P = 0.0015).
- SAC and WESS scores showed no significant differences based on concussion history or disability type.
Conclusions:
- Baseline symptom scores on the mGSC are elevated in disabled athletes with a concussion history and those with brain disorder disabilities.
- The SAC and WESS are not influenced by concussion history or disability type in this population.
- Baseline concussion testing is essential for disabled athletes, particularly those with brain disorders and a history of concussion.
