Summary
Single-task tandem gait (TG) is slower after sport-related concussion (SRC). Dual-task (DT) conditions, particularly the auditory pure switching task (APST) response rate, also aid in predicting SRC diagnosis and clinical decisions.
Area of Science:
- Sports Medicine
- Neurology
- Biomechanics
Background:
- Sport-related concussion (SRC) diagnosis can be challenging.
- Tandem gait (TG) is a sensitive measure for detecting neurological impairments.
Purpose of the Study:
- To evaluate dual-task (DT) conditions during TG for predicting SRC.
- To determine the utility of single-task (ST) and DT measures in SRC diagnosis.
Main Methods:
- A cohort study involving 409 NCAA Division I student-athletes (controls) and 21 with SRC.
- Participants completed TG under ST, DT with serial-7s (SS), and DT with auditory pure switching task (APST) conditions.
- Gait completion time and behavioral task performance were recorded.
Main Results:
- ST TG was significantly slower in SRC athletes compared to controls.
- APST response rate was significantly different between and within groups.
- DT completion times also showed significant differences related to SRC.
Conclusions:
- ST TG is a valuable objective marker for SRC.
- DT paradigms, especially APST response rate, offer complementary information for SRC prediction and clinical assessment.
- Both ST and DT measures should be considered in clinical evaluations of postural instability post-SRC.
