Assessment – Max Strength Evaluation

This assessment tests the maximal capacity of a muscle group in a specific situation. The max corresponds to 100% of the strength abilities. 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.

Assessment – Strength Endurance Assessment

This assessment allows to measure the ability to keep a physical effort over time. It is related to a long and sustained effort. The most relevant measurement indicator to describe the stamina is the average of the strength kept on a long given time. This evaluation highlights the fatigue rate of force as well.

Exercise – 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.

Rehab Gaming

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.

Scuba-diving

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.

Desert

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.

Reports – Result 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.

Reports – Result 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 is remaining before the recovery or the return to sport. Each KFORCE report can be exported in a PDF format.
