The Buffalo Concussion Treadmill Test (BCTT) is a graded exertion test for assessing exercise tolerance after concussion, but its utility is limited for certain populations.
We developed the Buffalo Concussion Bike Test (BCBT) and tested its comparability with the BCTT. We hypothesize that heart rate (HR) at symptom exacerbation on the BCBT will be equivalent to the BCTT.
Case-control study.
Level 3.
Adolescents with acute concussion (AC) (n = 20; mean age, 15.9 ± 1.1 years; 60% male) presenting to a concussion clinic within 10 days of injury and age- and sex-matched healthy controls (n = 20; mean age, 15.9 ± 1.1 years; 60% male) performed the BCTT at first visit and returned within 3 days to perform the BCBT. Test duration, HR, symptom severity (measured using a visual analog scale), and exertion (measured using the Borg Rating of Perceived Exertion) were collected during each test.
Adolescents with AC who were exercise intolerant on the BCTT were also intolerant on the BCBT, with symptom exacerbation occurring at a mean 8.1 ± 2.8 minutes on the BCTT versus 14.6 ± 6.0 minutes on the BCBT ( < 0.01). Two 1-sided tests showed that the HR at symptom exacerbation in AC patients (137 ± 28 bpm on BCTT vs 135 ± 25 bpm on BCBT; 95% CI, <0.01-0.03) and at voluntary exhaustion for controls (175 ± 13 bpm on BCTT vs 175 ± 13 bpm on BCBT; 95% CI, 0.03-0.03) on each test were statistically equivalent.
The HR at symptom exacerbation on BCBT is equivalent to the BCTT for the assessment of exercise tolerance after concussion in adolescents.
The BCBT can be used in patients with limited mobility or for research interventions that require limited participant motion.
布法罗脑震荡跑步机测试（BCTT）是一种分级用力测试，用于评估脑震荡后的运动耐量，但对于某些人群，其适用性有限。
我们开发了布法罗脑震荡自行车测试（BCBT），并测试了其与 BCTT 的可比性。我们假设 BCBT 上症状恶化时的心率（HR）与 BCTT 相当。
病例对照研究。
3 级。
在受伤后 10 天内就诊于脑震荡诊所的急性脑震荡（AC）青少年（n=20；平均年龄 15.9±1.1 岁；60%为男性）和年龄和性别匹配的健康对照组（n=20；平均年龄 15.9±1.1 岁；60%为男性）在首次就诊时进行 BCTT，并在 3 天内返回进行 BCBT。在每项测试中，收集测试持续时间、HR、症状严重程度（使用视觉模拟量表测量）和用力程度（使用 Borg 感知用力等级测量）。
在 BCTT 上运动不耐受的 AC 青少年在 BCBT 上也不耐受，BCTT 上症状恶化发生在平均 8.1±2.8 分钟，而 BCBT 上发生在 14.6±6.0 分钟（<0.01）。两次单侧检验表明，AC 患者在症状恶化时的 HR（BCTT 上为 137±28bpm，BCBT 上为 135±25bpm；95%CI，<0.01-0.03）和对照组在自愿衰竭时的 HR（BCTT 上为 175±13bpm，BCBT 上为 175±13bpm；95%CI，0.03-0.03）在每个测试上均具有统计学等效性。
BCBT 上症状恶化时的 HR 与 BCTT 用于评估青少年脑震荡后的运动耐量相当。
BCBT 可用于运动受限的患者或需要限制参与者运动的研究干预措施。
