loadsol application
Sport rehab force measurement inside footwear.
Use plantar normal force data to guide loading progression, asymmetry correction and return-to-sport decisions.
Objective load feedback during real exercises.
During sport rehabilitation, clinicians and researchers often need to know how much load an athlete actually accepts through the injured limb. loadsol places force measurement inside the shoe, allowing drills, walking, jogging and sport-specific tasks to be monitored without a fixed force plate.
Real-time visual or acoustic thresholds can help patients stay within target loading zones, while stored force curves allow later comparison of sessions, limbs and exercise conditions. For rehabilitation protocols, loadsol can be selected as a 1-zone total-force sensor, a 2-zone anterior/posterior layout, or a 3-zone regional layout when the study needs more detailed loading behavior.
Return-to-sport
Compare loading symmetry and peak force behavior across functional tests and sport drills.
Partial loading
Use feedback thresholds to train controlled weight bearing during progression phases.
Field testing
Collect force data outside the laboratory in shoes and environments that match the task.
Expanded application notes
Measurement questions and useful outputs.
How much load does the athlete accept, when does asymmetry appear, and can feedback keep the exercise inside the target zone?
Peak force, impulse, stance timing, loading-rate changes and left-right symmetry across return-to-sport drills.
Recommended setup
Choose the loadsol zone layout before testing: total area, anterior/posterior, or 3-zone regional force. Confirm shoe size, 10 - 200 Hz sampling needs, BLE or USB-C transfer, and whether optional loadsync synchronization is required.
Scientific value
The application becomes stronger when force data is synchronized with video, timing events, questionnaires, motion capture or operator notes.

Research and publications
Sport rehab and ACLR monitoring are strong loadsol publication themes.
The most relevant literature for this page focuses on landing kinetics, kinetic symmetry after ACL reconstruction, walking/running reliability and insole feedback for partial weight-bearing control.
