  • Fast assessment 
  • User friendly 
  • Versatile 


Max Grip Strength Assessment

This assessment tests the maximal grip strength. 100% corresponds to the maximal strength of the patient. It is related to a short and strong physical effort and it is very helpful as a work reference. The most relevant measured parameter is the force peak. 


Configuration Screen

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. 


10 Levels of Difficulties

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. 


This rehab-game makes Karl evolve like a Scuba Diver under the sea. Controlling their strength and motion in order to make Karl avoid the bad fishes while collecting as much as possible of pearls and diamonds, your patient will be happy to play. 


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 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.
