How Bandcizer works
A capacitive sensor clips onto the resistance band and measures deformation at 20Hz — force, timing, and quality for every rep. The app guides the patient. The dashboard shows the PT. Three components, one clinical workflow.

How It Works
Three simple steps to objective recovery data.
Clip
Attach the Bandcizer sensor to any flat resistance band.
Train
Patient follows the app's real-time guidance for tempo and repetitions.

The tempo problem nobody talks about
Your patients complete their prescribed reps. Every single one. But a 2024 study — using Bandcizer's own sensor to measure — found that actual time under tension dropped to 53% of prescribed levels within weeks. Even in supervised sessions.
They did the exercise. They just did it too fast. The eccentric phase gets rushed. The isometric hold gets skipped. The training stimulus — the thing that actually drives recovery — is cut nearly in half. And neither the patient nor the PT knows it's happening.
“Patients completed their reps but cut time under tension by 21–47% below prescription. They thought they were compliant. The sensor showed they weren't.”
Prescribe the tempo. We'll guide them through it.
The PT sets the tempo when prescribing an exercise — for example, 3-2-3: three seconds eccentric, two seconds isometric, three seconds concentric. The app's built-in tempo guide paces the patient through each phase of every rep.
Stretch (Eccentric)
Audio and visual cues count down the controlled lengthening phase. The patient hears and sees exactly how long to stretch the band.
Hold (Isometric)
A distinct tone signals “hold here” for the prescribed duration. No guessing when to transition.
Release (Concentric)
A final cue paces the controlled shortening. Or, for explosive protocols, a single “go” burst — the sensor measures the actual speed.
The patient follows the rhythm. The sensor measures what actually happened.
Other apps guide. Only Bandcizer verifies.
Every fitness app can prescribe exercises. Some can even guide tempo with timers. But no other system closes the loop by measuring whether the patient actually followed the prescribed tempo.
After every session, the PT sees:
Actual vs. prescribed TUT per phase, per rep
Tempo adherence score trending over weeks
Phase-specific patterns — "this patient consistently rushes the eccentric"
Software alone can prescribe and guide. But verifying actual force, time under tension, and tempo per phase per rep requires a physical sensor on the band. That's the moat.
Supports any tempo prescription
The PT prescribes any combination. The app adapts the metronome. The sensor measures the result.
| Protocol | Format | Example |
|---|---|---|
| Standard 3-phase | Eccentric – Hold – Concentric | 3-2-3 |
| No isometric hold | Eccentric – Concentric | 4-0-2 |
| Explosive concentric | Eccentric – Hold – Fast | 3-1-X |
| Isometric only | Static hold | 0-30-0 |
| Emphasis eccentric (tendon rehab) | Slow stretch | 6-1-2 |
