Pull dynamometer

Use the K-Pull for measuring isometric strength and biofeedback training with the KFORCE APP. Perform operator-independent measurements. It can be easily secured to a physiotherapist table, to wall bars or to a pulley system. K-Pull is provided with accessories for turnkey use :

  • 2 carabiners
  • 2 loop fastening accessories for securing and to the desired limb and to a physiotherapy table, to wall bars or to a pulley system
  • 2 different resistance elastics for exercise with resistance
  • 1 adjustable rigid strap for the measurement of the maximum isometric force.

Key features

  • Fast assessment
  • User friendly
  • Versatile


Max strength evaluation

This assessment tests the maximal strength. 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.



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.



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

Max test: the results allow to highlight the percentage of deficit or imbalance between both limbs. Each KFORCE report can be exported in a PDF format.

Results Over Time

One of the key points for progress in functional rehabilitation is motivation. Motivation can be powered by the ability to compare the starting point with the current state, as well as identifying how much effort is still remaining before the recovery or return to sport.
