Core Purpose
Assist physiotherapists to efficiently classify runners in rehabilitation as:
On Tracx: No follow-up is required.
Off Tracx: Follow-up required.
Soft Off Tracx
Hard Off Tracx
Active Check on
Pain Score: Latest score >4/10.
Pain Trend: Positive, neutral, or negative.
Load Progression: Exceeding target.
Weeks Exceeding Target: More than three.
Classification Thresholds
On Tracx: 0–1 positive checks.
Soft Off Tracx: 2–3 positive checks.
Hard Off Tracx: All checks are positive.
Common Scenario’s
Scenario 1: Consistently improving (On Tracx)
Latest pain value <4/10
Pain trend: negative or no trend.
Current load: close to or below the progression target.
Less than 3 weeks with a progression above the progression target
Scenario 2: Overloading progress with no pain response (Soft Off Tracx)
Latest pain value e.g. <4/10
Pain trend: neutral or negative.
Current load progress: exceeding progression target.
More than 3 weeks with a progression above the progression target
Scenario 3: Pain spikes despite load control (Soft Off Tracx)
Latest pain score: >4/10
Pain trend: positive trend (sudden increase in pain).
Current load: below progression target.
More than 3 weeks with a progression above the progression target
Scenario 4: Inconsistent adherence to progression target & early detected long-term increase in pain (Soft Off Tracx)
Latest pain: < 4/10
Pain trend: positive trend
Current load progression: below target
Weekly load progress: > 3 weeks above target
Scenario 5: Inconsistent adherence to progression target & response to pain (Hard Off Tracx)
Latest pain >4/10
Pain trend: positive trend
Current load progression: above target
Weekly load progress: > 3 weeks above target
