Grip Dynamometer

Kinvent K-Grip Hand Dynamometer

K-Grip is a wireless grip dynamometer. The hand closes on the handle, the sensor reads the squeeze, and the Kinvent app returns the force reading straight away. Kinvent position grip strength as an indicator of neuromuscular function, fatigue level and rehabilitation progress, which is why a number that takes two seconds to capture carries more weight than the effort suggests.

One squeeze gives maximum grip force. Beyond that single figure, the device supports isometric exercises and repetition-based training, and the app records the force live so the person squeezing gets biofeedback while the hand is still closed. At 2.2 lbs it goes in the bag between sites.

Instant force readings Max tests, isometrics, repetitions Grip-controlled rehab games Wireless and portable

The Technology

Four Things Kinvent Built Into It

Kinvent publish four features for K-Grip. Each one changes what a grip test can be used for inside a session.

✊

Instant force readings

Kinvent describe the assessment as fast and user-friendly: the force reading arrives while the hand is still on the handle, so muscle strength and fatigue level can be evaluated without a second pass or a separate calculation step.

Fast assessment

🔄

Three test modes, one device

Maximal grip strength tests, isometric exercises and repetition-based training all run off the same handle. The mode you pick decides whether you are recording a single peak or watching force hold or fall across a set.

Versatile testing

🎮

Rehab gaming

Grip force drives interactive games in the app. Kinvent list this against compliance and training efficiency, which is the honest reason it exists: a patient who is aiming at something on screen keeps going longer than one squeezing at nothing.

Compliance

📶

Wireless and ultra-portable

Bluetooth pairing with no cable and no base unit, at 2.2 lbs and 11.81 x 3.74 x 7.87 in. Kinvent aim this specifically at healthcare professionals working across more than one location.

Maximal Testing

Peak Grip Force, Read On The Spot

The maximal grip strength test establishes a strength baseline and exposes imbalances between sides. Nothing in the test depends on the tester's own strength or on how the device is braced, which is what makes the figure worth comparing against the same person a month later.

Training Modes

Isometric Work And Repetition Sets

Kinvent build targeted isometric and dynamic exercises into the app with adjustable intensity levels, so the same sensor that took the baseline runs the work that follows it. The grip games sit in the same place, using live force as the control input.

Assessment

Two Seconds Of Effort, Tracked Over Months

Kinvent name grip strength as an important indicator of neuromuscular function, fatigue levels and rehabilitation progress. That is three separate jobs for one measurement, and it is the reason a grip test earns its place in an assessment battery that is already short on time.

Key Applications

What Kinvent Built It For

Kinvent publish four applications for K-Grip and name clinical rehabilitation, sports performance and research as the settings it is used in.

🎯

Maximal Grip Strength Testing

Determines peak grip force to establish strength baselines and identify imbalances.

🩹

Rehabilitation And Injury Recovery

Assists hand therapy and upper limb rehabilitation for post-injury and post-surgery recovery.

🧠

Neuromuscular Fatigue Monitoring

Helps athletes and clinicians track nervous system fatigue and adjust training loads accordingly.

🏋️

Customized Strength Training

Targeted isometric and dynamic exercises with adjustable intensity levels.

🎮

Gamified Rehab Sessions

Interactive grip-based games that Kinvent tie to patient compliance and training efficiency.

The App

One App Behind Every Test

Kinvent App

Measurement, Feedback And Progress Tracking

K-Grip pairs to the Kinvent app over Bluetooth, and Kinvent describe that pairing as delivering accurate measurements, immediate feedback and ongoing progress tracking across clinical, athletic and research settings. The same app runs the rest of the Kinvent sensor family, so a clinic adding K-Grip is not adding a second system to learn.

The Kinvent Lineup

Three Dynamometers, Three Kinds Of Force

All three pair to the Kinvent app. The difference is where the force comes from and how it reaches the sensor.

Questions

Frequently Asked Questions

Grip strength, taken from the force the hand applies to the handle. Kinvent describe grip strength as an important indicator of neuromuscular function, fatigue levels and rehabilitation progress, and the headline test on the device is maximal grip strength, which returns peak grip force.

No. Kinvent's K-Grip page carries no measurement range, no accuracy percentage and no sampling rate. What they do publish is the function: a wireless grip dynamometer giving instant force readings through the Kinvent app. The hard numbers on this page are the ones in our own specification, which covers size and weight. We will not quote a precision figure nobody has published.

Kinvent publish no autonomy or charge-time figure for K-Grip. Their published description of the power side is that the unit is wireless and Bluetooth-enabled, aimed at healthcare professionals on the go. If battery life is a deciding factor for you, ask us before ordering rather than working from a number we invented.

A maximal grip attempt is a short, hard effort. Kinvent describe the assessment as fast and user-friendly with instant force readings, so the value is on screen while the hand is still closed on the handle.

Yes. Kinvent list three modes: maximal grip strength tests, isometric exercises and repetition-based training. The app also carries targeted isometric and dynamic exercises with adjustable intensity levels, so the same device that records the baseline runs the training that follows.

Live grip force becomes the control input for interactive games in the Kinvent app. Kinvent tie this directly to patient compliance and training efficiency: giving someone a target on screen keeps them working through a set they would otherwise cut short.

Yes. Kinvent list the maximal grip strength test as determining peak grip force to establish strength baselines and identify imbalances. Test both hands and the two figures sit side by side in the record.

Over Bluetooth to the Kinvent app on a phone or tablet. There is no cable and no base unit, so the working setup is the dynamometer and the screen already in the room.

Published at 11.81 x 3.74 x 7.87 in and 2.2 lbs. That is the figure behind Kinvent's claim that it is ultra-portable and suited to professionals working across more than one site.

The K-Grip dynamometer and its accessories. Kinvent do not itemise the accessory set piece by piece on their product page, so we are not going to list contents we cannot point to. Ask us for the current packing list before you order if the exact contents matter.

Kinvent name three settings: clinical rehabilitation, sports performance and research. In practice that means hand therapists and upper limb rehabilitation, clinicians and coaches monitoring neuromuscular fatigue, and research groups needing a repeatable strength figure.

Kinvent's K-Grip product page publishes no warranty term, so there is no figure for us to quote here. Contact us for the warranty and returns position that applies to your order.

They answer different questions. K-Grip is dedicated to the hand: the patient does all the work, so the number does not depend on the tester. K-Push is a handheld unit the tester presses against a limb, covering muscle groups K-Grip cannot reach. Clinics assessing both hand and limb strength commonly run the pair, and both report into the same Kinvent app.
