Portable Goniometer

Kinvent K-Move

K-Move is a portable goniometer that measures how far a joint travels and writes the reading straight into the Kinvent app. Kinvent publish accuracy better than 0.5 degrees with minimal drift over time, which is the figure that separates it from a plastic arm goniometer and a clipboard. Inside the housing sits a nine-degree-of-freedom inertial unit combining an accelerometer, a gyroscope and a magnetometer.

It records joint range of motion in a chosen anatomic plane, covering flexion, extension, abduction, adduction and rotation, and it compares an injured limb against a healthy one in the same view. A maximum amplitude captured for a joint becomes the 100% reference the app works from afterwards, including the target games, whose difficulty can be set as a percentage of that maximum across ten levels. Kinvent build it for physical therapists, trainers and sports professionals, from clinic to field. Accessories are included with the sensor.

The Measurement

What a connected goniometer adds

A manual goniometer gives you a number that then has to be written down. K-Move takes the same angle and files it against a profile, with a published tolerance attached to it.

📐
Accuracy stated in degrees
Kinvent publish better than 0.5 degrees for K-Move, with minimal drift over time. A tolerance that small is what lets you treat a four-degree change between week one and week six as a real change rather than measurement noise.
< 0.5°
🧭
Nine degrees of freedom
Three sensing elements work together in the unit: an accelerometer for linear motion, a gyroscope for rotation, and a magnetometer for heading. Nine axes of data resolve into one joint angle, so the reading holds whether the limb is on a table or mid-squat.
9 DOF
↔️
Injured side against healthy side
Kinvent list symmetry analysis for K-Move, comparing injured and healthy limb performance. That comparison is the one a return-to-play decision usually turns on, and here it comes out of the same sensor on the same visit.

🔋
Seven-hour battery in a 2.2 lb kit
Kinvent list seven hours of use and a compact, wireless build. Seven hours covers a full clinic day of short measurements without a charging break, and 2.2 lbs with accessories travels to a pitch-side assessment without a case of its own.

Taking the reading, then using it

Measuring

One joint, one plane, one figure

You choose the joint and the plane, then take the largest amplitude the movement reaches. Kinvent quote better than 0.5 degrees on that reading with minimal drift. The nine-degree-of-freedom unit works out where the sensor is pointing from accelerometer, gyroscope and magnetometer data together, which is why the number holds through a moving test rather than only a held end position.

  • Flexion, extension, abduction, adduction and rotation
  • Accuracy published as better than 0.5 degrees
  • Nine axes of inertial data behind each angle
  • Reading lands in the Kinvent app as it is taken

Targets

The maximum becomes the scale

Once a maximum amplitude is recorded, it stands as the 100% mark for everything that follows. Game targets are set as a percentage of it, and each game carries ten levels of difficulty. A session run at 60% of a stored maximum is a defined piece of work with a number attached to it, which is easier to hand to a patient than an instruction to go as far as feels comfortable.

  • Maximum amplitude held as the 100% reference
  • Targets set as a percentage of that maximum
  • Ten levels of difficulty in each game
  • Real-time feedback while the movement is happening
Percentage targets Ten levels

Movement

Off the table and into the movement

Kinvent list squats, jumps and walking gait analysis among the applications for K-Move, alongside post-injury mobility tracking. The sensor is compact and wireless, so the same unit that takes a passive knee angle on a plinth goes on to evaluate motion efficiency in a loaded squat without swapping hardware or losing the patient profile.

  • Rehabilitation and injury assessment after a layoff
  • Squats, jumps and walking gait analysis
  • Kinematic data for clinical and research use
  • Clinic, gym floor or field with the same sensor

The Kinvent App

What lands on the screen

Angles you can read back later

K-Move reports into the Kinvent app, which shows joint angles as the movement happens and keeps each reading against a profile so mobility progress can be compared over time. Assessments are filtered by exercise, with squats, neck flexion and trunk flexion among the entries, and the Sit-to-Stand Test is one of the tests available. Data can be exported out of the app.

Questions

Frequently Asked Questions

Joint range of motion, in degrees. Kinvent categorise it as a portable goniometer, and it records the amplitude a joint reaches in a nominated anatomic plane.
Kinvent name flexion, extension, abduction, adduction and rotation. The measurement is taken for one joint in one plane at a time.
Kinvent publish better than 0.5 degrees, with minimal drift over time. That is the only accuracy figure they state for this sensor, and it belongs to K-Move alone.
Three sensing elements of three axes each: an accelerometer, a gyroscope and a magnetometer. Their combined output is what the unit resolves into a joint angle.
Seven hours, as Kinvent list it. They publish no charge-time figure, so we do not print one.
Yes. Kinvent list symmetry analysis for K-Move, comparing injured and healthy limb performance, so an angle taken on the left can be read against the same measurement on the right.
It sets the scale. The largest amplitude recorded for that joint counts as 100%, and later target work is expressed as a percentage of it.
They are target exercises inside the Kinvent app. Each carries ten levels of difficulty, and the target itself can be set as a percentage of a stored maximum evaluation.
Real-time joint angle tracking, mobility progress compared over time, and an assessment list filtered by exercise with squats, neck flexion and trunk flexion among the entries. The Sit-to-Stand Test is one of the available assessments, and motion data can be visualized and exported.
No. Kinvent list it for use from clinic to field, and name squats, jumps and walking gait analysis alongside post-injury mobility tracking. The unit is compact and wireless at 2.2 lbs as listed.
Kinvent name physical therapists, trainers and sports professionals, plus researchers needing kinematic data. Their own framing is clinics, research labs and pro sports.
It does. Every unit in the range reports into the same Kinvent app, so angle data from K-Move sits beside force readings from the K-Force Plates, the K-Deltas or the K-Push, and EMG from the K-Myo Duo Pack.
The listing states that accessories are included without itemising them. Kinvent publish no parts list for this sensor, so ask before you assume a particular strap or mount is in the box.
11.81 in x 3.74 in x 7.87 in and 2.2 lbs as listed. Those figures cover the sensor with its accessories rather than the sensor body alone.
No to both. Kinvent state the angle tolerance, the drift behaviour and the battery life for this unit and nothing about sampling frequency or warranty length, so those are the figures we will put in writing. Ask us before you buy on a warranty assumption.
