Abstract
Objective
To examine the influence of biopsychosocial factors on clinical outcomes and recovery time following SRC
Method
59 athletes with SRC (51% male) aged 14.42, SD= 1.65 years from two concussion specialty clinics between May 2019 and January 2020. Patients completed the Behavioral Regulation Assessment for Concussion (BRAC) inventory measuring sleep, diet, hydration, physical activity and stress; on a 4-point Likert scale, ImPACT, and PCSS. Analyses included one-way ANOVAs with Tukey’s post-hoc test and chi-square analyses.
Results
Verbal memory scores were higher F(3,55)= 2.85, p<.05 in participants reporting 8-10hrs of sleep “most of the time” (M= 85.12, SD = 10.58) vs. “some of the time “ (M= 75.65, SD= 11.91). Verbal memory differed when engaged in stress regulation F(4,54)= 2.65, p<.05; “MOT” (M=81.38, SD= 10.95); “SOT” (M=82.33, SD= 12.64) and “never” (M= 84.05, SD= 13.07). PCSS sleep factor scores increased when individuals obtained 8-10hrs of sleep “MOT” (M=.30, SD=.423) “SOT” (M= 1.40, SD= 1.54) and “seldom/rarely” (M= 1.95, SD= 1.58). PCSS somatic scores were associated with decreased sleep X2(1, N=57) = 37.68; p= .001, and hydration X2(1, N=57) = 60.70 p< .001. Sleep and recovery time X2(1, N=55) = 120.82 p= .028.
Conclusions
Findings suggest that biopsychosocial factors including sleep, stress, and hydration are associated with symptoms, cognitive function, and recovery time following SRC and should be monitored by clinicians.
