Clinical Assessment of Sports Exertion (CASE)

February 6, 2026 updated by: Baylor Research Institute

Baylor Scott and White Sports Concussion Program Clinical Assessment of Sports Exertion Research Proposal

The Clinical Assessment for Sports Exertion (CASE) addresses the physical performance of athletes by quantifying physiological and symptomatic responses to dynamic exertion. The CASE is highly sport-specific as it tests multiple body positions that mimic requirements typical of individual and contact sports activities including soccer, gymnastics, cheerleading, swimming, and basketball. It was developed by clinicians at the Baylor Scott and White Sports Concussion Program in an effort to identify specific system impairments in athletes who were unable to successfully demonstrate readiness for return to play protocols. Like the other published forms of concussion exertion testing described above, the CASE is a provocative exercise test that may also prove to be useful in making informed return-to-play decisions based upon the athlete's symptomatology.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: CASE
In this prospective study the investigators aim to quantify participants' responses to physical activity. Participants will be asked to engage in physical activity, to identify any provocation of symptoms in adolescents ranging from ages 10 to 22 years. Responses to physical activity will be measured through physiologic markers (e.g., blood pressure, heart rate, oxygen saturation, rate of perceived exertion, dyspnea). Additionally, participants will be monitored for any changes in symptoms that occur during or after physical activity as measured by the modified PCSS symptom inventory.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Heart rate (bpm)
Time Frame: through study completion, an average of 1.5 hours
Using pulse oximeter placed on index finger heart rate will be recorded.
through study completion, an average of 1.5 hours
Blood pressure (mmHg)
Time Frame: through study completion, an average of 1.5 hours
Using a manual cuff and auscultation method diastolic and systolic scores will be recorded.
through study completion, an average of 1.5 hours
Oxygen Saturation (%)
Time Frame: through study completion, an average of 1.5 hours
Using pulse oximeter placed on index finger oxygen saturation will be recorded.
through study completion, an average of 1.5 hours
Rate of Perceived Exertion (Borg 6-20)
Time Frame: through study completion, an average of 1.5 hours
Using Borg Scale, self report measure of exertion will be recorded. A higher number indicates higher exertion.
through study completion, an average of 1.5 hours
Self-rated lightheadedness (0-6)
Time Frame: through study completion, an average of 1.5 hours
On a scale of 0-6, a self report measure of lightheadedness will be recorded. A higher number indicates worse lightheadedness.
through study completion, an average of 1.5 hours
Self-rated dyspnea (Modified Borg 0-10)
Time Frame: through study completion, an average of 1.5 hours
Using Borg scale, self report measure of dyspnea will be recorded. A higher number indicates worse dyspnea.
through study completion, an average of 1.5 hours
Heart rate reserve (peak-rest), beats/min-1
Time Frame: through study completion, an average of 1.5 hours
Using metabolic cart, heart rate reserve will be recorded via Garmin heart rate strap.
through study completion, an average of 1.5 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Modified Post-Concussion Symptom Scale (PCSS) (0-6)
Time Frame: through study completion, an average of 1.5 hours
Using modified PCSS, self report measure of symptoms will be recorded. A high number indicates worse symptoms.
through study completion, an average of 1.5 hours
