Buffalo Concussion Treadmill Test: The Exercise Prescription That Accelerates Recovery
Dr. Rob Letizia PT, DPTShare
Written by Dr. Rob Letizia, PT, DPT - post-concussion specialist serving athletes across Wayne NJ and North Jersey.
If your athlete had a concussion weeks ago but still can't run, bike, or do any aerobic exercise without symptoms flaring, you are looking at a classic sign of exertional intolerance - an autonomic nervous system dysfunction that affects 60-80% of persistent post-concussion patients.
The Buffalo Concussion Treadmill Test (BCTT) is the single most valuable diagnostic and treatment-planning tool available for this problem. It is also one of the most underutilized - most PTs do not offer it, and most athletes never even hear about it.
Here is what the BCTT is, how it works, and why it accelerates recovery for athletes stuck in the "post-concussion plateau."
What Is the Buffalo Concussion Treadmill Test?
The BCTT is a graded exercise test developed at the University of Buffalo Concussion Management Clinic (UBMD Sports Medicine) and validated across dozens of peer-reviewed studies. The protocol is straightforward: the athlete walks or runs on a treadmill with incrementally increasing speed and grade every minute, while the clinician monitors heart rate, blood pressure, and concussion symptoms in real time.
The test continues until either:
- The athlete develops significant symptoms (dizziness, headache, nausea, visual disturbance, brain fog)
- Or the athlete reaches age-predicted maximum heart rate and completes the test symptom-free
The heart rate at which symptoms appear is the symptom threshold heart rate (STHR) - a critical data point for everything that comes next.
What the Test Identifies
The BCTT answers three questions that shape the entire rehab plan:
- Does the athlete have exertional intolerance? If yes, symptoms appear at sub-maximal heart rates. If no, the athlete reaches max HR symptom-free and can progress in return-to-play more aggressively.
- Where is the symptom threshold? This determines the exact training heart rate zone for sub-symptom-threshold aerobic exercise (typically 80-90% of STHR).
- Is the autonomic nervous system recovered? Abnormal heart rate response to exertion (slow to rise, abnormal HR variability) is a direct objective measure of autonomic dysfunction.
Athlete Plateaued in Their Concussion Recovery?
The Buffalo Concussion Treadmill Test is available at Spectrum Therapeutics of NJ as part of our post-concussion evaluation. Most athletes see significant progress within 2-4 weeks of adding sub-symptom-threshold aerobic training.

Before the BCTT was developed, the standard concussion advice was "rest until you feel better, then gradually return to exercise." This turned out to be actively harmful after the first 24-48 hours:
- Extended rest causes cardiovascular deconditioning, which makes any exercise feel harder and provoke more symptoms
- The autonomic nervous system needs graded aerobic stimulus to recalibrate after concussion
- Exercise at sub-symptom-threshold intensity has a therapeutic effect on the concussed brain - it does not just maintain fitness, it actively accelerates neural recovery
Research in JAMA Pediatrics, the British Journal of Sports Medicine, and the Clinical Journal of Sport Medicine consistently shows that athletes who receive sub-symptom-threshold aerobic training recover faster than those prescribed rest.
How Dr. Rob Runs the BCTT
At Spectrum Therapeutics of NJ, the BCTT is part of the comprehensive 4-domain post-concussion evaluation:
Pre-Test
Baseline symptom scoring using a validated concussion symptom inventory. Resting heart rate and blood pressure.
Warm-Up
2 minutes walking at 3.2 mph at 0% grade.
Incremental Increase
Every minute, grade increases by 1%. Speed typically stays constant, though for older athletes or deconditioned patients we adjust the protocol.
Continuous Monitoring
Heart rate, perceived exertion, and concussion symptoms checked at each minute mark.
Stopping Criteria
Symptom onset, achievement of age-predicted max HR, or pre-determined endpoint.
Post-Test Analysis
The STHR (symptom threshold heart rate) becomes the key variable. Sub-symptom-threshold training heart rate (typically 80-90% of STHR) is calculated and prescribed.
Treatment Plan Using BCTT Data
With the STHR identified, Dr. Rob prescribes a structured aerobic training program:
Week 1-2
15-20 minutes of exercise (walking, stationary bike) at 80% STHR, 5 days per week. Keep HR below the prescribed ceiling. Log symptoms daily.
Week 3-4
Increase duration to 25-30 minutes. Begin increasing HR ceiling by 5-10 bpm if symptoms remain controlled.
Week 5+
Repeat BCTT to quantify progress. If STHR has risen or disappeared (exercising without symptoms at max HR), progress to return-to-play protocol stages.
Most athletes see their STHR rise steadily over 4-8 weeks, eventually reaching full tolerance.
Why Most PTs Do Not Offer the BCTT
The BCTT requires specialized training in concussion management, familiarity with the research protocol, and comfort managing symptom provocation in a controlled setting. Most general outpatient PTs do not treat enough concussion patients to develop this expertise, and most concussion-specialized clinics in New Jersey are located in major hospital sports medicine programs.
Spectrum Therapeutics offers the BCTT in a dedicated one-on-one setting with Dr. Rob Letizia, DPT, who has integrated the Buffalo protocol into concussion care since the original research was published.
The Bottom Line
If your athlete is stuck in their concussion recovery, cannot exercise without symptoms flaring, and has been told to "just keep resting," the Buffalo Concussion Treadmill Test is likely the breakthrough diagnostic tool they need.
