abstract="OBJECTIVES: We hypothesized that a submaximal step test would be associated with readiness to commence graded exercise in children and adolescents with concussion. <br><br>METHODS: Children and adolescents aged 8 to 18 years performed standard concussion clinical assessment for vestibular/ocular and balance impairment, and exercise examination utilizing the 3-minute Kasch Pulse Recovery test (KPR) and a symptom-limited graded exercise test (GXT). Outcome measures included activity readiness and symptom exacerbation. <br><br>RESULTS: Forty-five participants (mean age 13.2 ± 2.1 years, 76% male) had a confirmed concussion (73% sports-related). Some participants required follow-up testing giving 75 clinical presentations. Sensitivity and specificity of the KPR were 100% and 95.7%, respectively. Area under the receiver operating characteristics curve was 0.979. Activity readiness to GXT and KPR was strongly associated (χ = 21.672, P <.001), while symptom exacerbation showed a significant correlation between testing methods (r = 0.796, P <.001). Better exercise performance on GXT and KPR was significantly correlated with normal Vestibular/Ocular Motor Screening (rs = -0.380, P =.010, and rs = -0.281, P =.017, respectively) and Modified Balance Error Scoring System (rs = -0.452, P <.001, and rs = -0.301, P =.010, respectively). <br><br>CONCLUSION: The KPR is a simple and practical tool to determine whether it is appropriate for a child or adolescent with concussion to commence graded exercise.<p /> <p>Language: en</p>",
