Portable Force Plates

Kinvent K-Force Plates

A pair of portable platforms that measure vertical force under each foot and report how a load is shared between the two sides. Kinvent list a capacity of up to approximately 600 kg per platform, which is why the same pair records a quiet standing trial, a loaded squat and an isometric mid-thigh pull without swapping equipment.

The plates are listed at 11.02 lbs and 19.69 x 5.91 x 15.75 in, so they move between a treatment room, a gym floor, a field session and a lab. Everything they record reads live in the Kinvent app, and the app writes the assessment report from the recorded session.

What The Plates Do

Four Jobs, One Pair Of Platforms

Kinvent group the plate protocols into balance work, dynamic movement, isometric strength and the software that records them.

🎯

Balance and postural control

Bilateral and single-leg stance assessed under static conditions, with center of pressure and CoP velocity reporting how accurately posture is controlled. The confidence ellipse puts a number on postural sway magnitude, and the Romberg test compares eyes open against eyes closed to expose visual dependency.

CoP, ellipse, Romberg

🏋️

Dynamic functional movement

Squats, sit-to-stand and single-leg squats for the lower body, the push-up force test for the upper body, and the Bridge Hamstrings Test for the posterior chain. Each returns force production and weight distribution, so a movement a clinician used to watch now comes back as a left-against-right split.

Up to 600 kg per plate

💪

Isometric strength testing

IMTP, the ASH Test, the Isometric Bridge and the McCall Test all run on the plates. Results come back as maximum strength, as relative strength normalized to body weight, and as a Limb Symmetry Index so asymmetry is read as a ratio rather than an impression.

IMTP, ASH, McCall

📊

Live feedback and reporting

The Kinvent app carries real-time visualization and monitoring during the trial, then generates the assessment report automatically. The numbers on screen while the athlete is still on the plates are the numbers that land in the record, with no separate write-up step.

Four Ways The Plates Get Used

Kinvent K-Force Plates set up for a standing balance assessment

Balance and posture

Standing trials, bilateral and single leg

One foot per platform gives the two-sided picture: the center of pressure path for the stance, the split between the tips and heels of the feet, and the percentage of body weight carried left against right. Stand on one leg and the same indicators come back for that side alone, which is what a return-to-sport conversation usually turns on.

Range of movements assessed on the Kinvent K-Force Plates

Dynamic movement

Squats, sit-to-stand, push-ups and bridges

The capacity of roughly 600 kg per platform is what lets a loaded squat run on the same pair used for quiet stance. Force production and weight distribution are recorded through the movement, so a compensatory strategy that only appears under load has somewhere to show up.

Isometric strength test performed on the Kinvent K-Force Plates

Isometric testing

IMTP and the isometric battery

Four named isometric protocols run on the plates: the Isometric Mid-Thigh Pull, the ASH Test, the Isometric Bridge and the McCall Test. Maximum strength on its own says little across a squad, so the app also returns relative strength normalized to body weight and a Limb Symmetry Index for the asymmetry between sides.

App exercises

Games with a target taken from the assessment

The Kinvent app carries games driven by live plate data. Each one takes a target expressed as a percentage of the maximum recorded during that person's own evaluation, so the number on screen is scaled to them rather than to a generic standard. Every game carries ten difficulty steps to work through.

Ten levels of difficulty in every game

Shoulder-loaded work on the plates
Run with or without belt straps for reduced weight loading

Where They Get Used

Six Jobs Kinvent Put The Plates To

Kinvent list clinics, rehabilitation centers, the field, gyms and laboratories as the settings, and physical therapists, sports performance staff, physicians, researchers and patients as the users.

🛡️

Injury prevention

Screening balance, force production and side-to-side distribution before a problem shows up in training.

🩺

Rehabilitation monitoring

Repeating the same protocol through a rehab block so progress is a number rather than a judgement call.

🔁

Return-to-sport decisions

Single-leg trials, landing stability and the Limb Symmetry Index give the discharge conversation something to sit on.

🏆

Sports performance testing

IMTP and the rest of the isometric battery, with relative strength normalized to body weight for squad comparison.

🔋

Neuromuscular fatigue detection

Kinvent list fatigue detection among the applications, read against that athlete's own recorded baseline.

⚖️

Asymmetry identification

Asymmetry and imbalance analysis, plus tracking of the compensatory strategies an athlete falls back on.

Questions

Frequently Asked Questions

Vertical force under each foot, and everything Kinvent derive from it. That includes center of pressure and CoP velocity, the confidence ellipse for postural sway magnitude, the Romberg ratio, maximum strength, weight distribution, relative strength normalized to body weight and the Limb Symmetry Index. All of it reads in the Kinvent app.

Kinvent publish a capacity of up to approximately 600 kg per platform. That is why the same pair handles a quiet standing trial and a loaded squat without swapping equipment. Kinvent give the number as an approximation and we publish it that way.

The listing gives 19.69" x 5.91" x 15.75" and 11.02 lbs. Kinvent do not state whether that mass covers one platform or the pair, so treat it as the figure they publish and confirm with us before planning a shipping weight around it.

No. Kinvent describe the plates as offering clinical accuracy and reproducibility, but they publish no sampling frequency and no measurement accuracy figure for this product. We will not quote a number they have not stated, and any figure published for the larger K-Deltas platforms belongs to that product alone. If you need a sampling rate in writing for a research protocol, ask us and we will put the question to Kinvent.

Kinvent name bilateral and single-leg balance under static conditions, the Romberg test with eyes open and eyes closed for visual dependency, center of pressure and CoP velocity, the confidence ellipse and landing stability, which evaluates the ability to absorb force and regain a stable posture after a controlled landing.

Yes. Kinvent list four isometric protocols on the plates: the IMTP (Isometric Mid-Thigh Pull), the ASH Test, the Isometric Bridge and the McCall Test. Output includes maximum strength, relative strength normalized to body weight, and Limb Symmetry Index asymmetry analysis.

Kinvent name squats, sit-to-stand and single-leg squats for the lower body, a push-up force test for the upper body, and the Bridge Hamstrings Test for the posterior chain, which assesses force production and force maintenance during a dynamic task. Force production and weight distribution are recorded for each.

Each game is driven by live plate data and aimed at a target. The target is set as a percentage of the maximum recorded during the evaluation, so it is scaled to that individual's own result, and each game carries ten levels of difficulty. These are software features of the Kinvent app.

Plate work can be run with or without belt straps, the strapped version being for reduced weight loading. Both variants are recorded through the same plates and read in the same app.

The Kinvent app does. It carries real-time visualization and monitoring during the trial and automatic generation of your reports and assessments afterwards. What appears on screen while the athlete is on the plates is the same data that ends up in the record.

Yes. Kinvent list compatibility with K-Push, K-Pull, K-Power, K-Myo and K-Move, all running through the Kinvent app. One session can therefore hold a plate trial and a K-Push or K-Move measurement under the same profile.

Kinvent list force plate frames as their own item, both standalone and in a version supplied with K-Force Plates. They publish no package contents list for the plates themselves, so we do not state what ships in the box. Ask us before ordering if you need the frames included and we will confirm the configuration.

Kinvent name physical therapists, sports performance professionals, physicians, researchers and patients as the users, across clinics, rehabilitation centers, the field, gyms and laboratories. The portability is the reason the same pair covers more than one of those settings.

The K-Force Plates are the portable, vertical-force option, built around balance, functional movement and isometric testing. The K-Deltas use a larger plate surface for dynamic force, symmetry and jump analysis, and the 3D Deltas capture force on multiple axes for postural and gait analysis. Those are the differences Kinvent publish, so those are the only ones stated here.

Kinvent publish CE marking, FDA registration, ISO 13485, ISO 9001:2015, ISO 27001:2022, HDS and HIPAA compliance at company and platform level. Those cover the company, its medical device quality system and its data handling. They are not a performance claim about these plates, and for class or registration questions in your territory, contact Kinvent or ask us and we will put the question to them in writing.
