Movement sensor

K-Move developed by KINVENT is an electronic connected goniometer. It’s an inertial sensor allowing the assessment, monitoring and rehabilitation of the range of motion of the main body joints. K-Move measures the angle regarding to the zero-starting position of the involved limb for a specific anatomic plane. Easy to use, it works through the KFORCE App.

Key features

  • Fast assessment
  • User-friendly
  • Real-time biofeedback


Max range of motion evaluation

This assessment measures the maximal movement amplitude for a specific body joint in a specific anatomic plane (flexion, extension, abduction, adduction, rotation). The max corresponds to 100% of the range of motion abilities. It is very helpful as a work reference. The most relevant measured parameter is the range Peak (in °).




Exercises are customizable in order to train the patient or athlete on a targeted zone and optimize the work. Following the assessment results, the target zone is adjustable to a percentage of the max evaluation.

Repetition Counts

Based on the assessment reference, you will train your patients on a specific number of repetitions to reach a specific target (% of the max). With the Reps Counts, you will control in real-time the achievement as well as the pace of the repetitions. A repetition is counted when there is a muscles contraction & release cycle.

Isometric exercise

On the opposite of the Reps count, this exercise requires a sustained and static movement instead of squeeze & release contraction cycles. It implies to keep the muscle contraction while keeping a steady position, and it requires control and accuracy of the level of strength. You can set a target for your patients.



On more challenging

Meet Karl, the KINVENT’s kangaroo who moves in different playful setups. The games are customizable in order to train the patient or athlete with fun and towards a target, which can be adjusted in terms of percentage of the Max Evaluation, depending on the assessment results. Moreover, there are 10 levels of difficulty for each game, proposing an extra challenge to the patient/athlete.


Karl is a Scuba Diver! Your patient will have fun controlling motion and strength in order to avoid the mean fishes while collecting a fortune of pearls and diamonds.


This rehab-game makes Karl evolve with his hang-gliding in the desert. Controlling their strength and motion in order to make Karl avoid the cactus while collecting as much as possible of tree-leaf and butterflies, your patient will be happy to play.



Results Details

Results details of a max assessment isometric strength for a horizontal shoulder abduction. The results allow to highlight the percentage of deficit or imbalance of the injured shoulder compared to the healthy one on this specific movement. Each KFORCE report can be exported in a PDF format.

Results Over Time

The key to progress for the functional rehabilitation is the motivation. This motivation can be powered by the measurement and the ability to compare the starting point regarding the current state as well as how much effort are still remaining before the recovery or the return to sport.
