Axis 1 · ROM
Range of motion in degrees.
Knee or shoulder, every session, documented automatically. Phase 1 after surgery, when classic tests would still be too painful.
Return is a decision. We measure it.
When can someone go back on the field after surgery? Today that call is often made on gut feeling, or in an expensive lab at a single appointment. Beyond Motion makes the Limb Symmetry Index visible in everyday practice. Week after week.
The decision
Without objective symmetry, return-to-play stays a risk estimate.
90 % LSI is treated as the benchmark. But who actually measures it in practice? In most clinics it comes down to a single knee test and gut feeling.

Limb Symmetry Index as the clearance criterion. Only when the values are consistently above 90 % does return-to-play even get discussed.
Axis 2 · strength asymmetry
Left versus right.
Peak strength side-by-side, without a strength-testing lab. The early loading phase, when asymmetries can still be corrected.
Axis 3 · jump LSI
Single-leg hop on the smartphone.
Drop-jump and hop tests, symmetry index right on site. The number that ultimately decides return-to-play.
Signature · LSI trajectory
A line that has to be broken through.
The Limb Symmetry Index, week after week. The dashed line marks the 90 % threshold. Points above it light up — visual anchors for the decision.

Anonymous pilot scenario · player K.
24 years old. ACL reconstruction in February.
Before · without continuous measurement
- Rehab with standard tests every 2 weeks, otherwise gut feeling.
- LSI measured only once in the lab before the intended clearance.
- Coach and sports orthopaedics talk about tables, not trajectories.
12 weeks with Beyond Motion
- Wk 13: 90 % threshold crossed · trajectory visible to the clinic.
- Wk 14: clearance consolidated, coach looking at the same picture.
- 3 / 3 return-to-play criteria met: objective, not on gut feeling.
