Abstract
BACKGROUND: Sleep deficits are associated with motor and cognitive function deficits, even in the absence of a recent concussion. RESEARCH QUESTION: Does the amount of self-reported sleep prior to pre-season concussion testing affect single-task and dual-task instrumented steady-state gait and timed tandem gait test performance? METHODS: One hundred and fourteen healthy collegiate athletes (mean age 18.8 ± 0.7 years; 60% female) reported the amount of sleep they received during the prior night and completed a timed tandem gait test and an instrumented assessment of steady-state gait in both single-task and dual-task conditions. Outcome variables included spatio-temporal gait parameters during steady-state gait, best and mean tandem gait times, and cognitive test accuracy. RESULTS: Participants who reported sleeping <7 h of sleep during the night prior to testing (n = 62) had significantly longer tandem gait times in single-task and dual-task conditions (11.1 ± 2.2 vs. 10.1 ± 2.0 s and 14.5 ± 4.3 vs. 12.3 ± 2.6 s, respectively; p = .009) compared to those who reported sleeping ≥7 h (n = 52). No significant differences between groups were observed for spatio-temporal steady-state gait variables or for cognitive test accuracy. SIGNIFICANCE: Self-reported sleep duration may be associated with baseline testing tandem gait performance. Thus, as sleep can play a role in motor abilities, clinicians may consider interpreting tandem gait performance in light of sleep duration during the night prior to testing.
