PKMAS - ProtoKinetics Movement Analysis Software

The Gold Standard in Gait Analysis Software

PKMAS – ProtoKinetics Movement Analysis Software

ProtoKinetics PKMAS software effortlessly outputs temporal, spatial and pressure measures for a wide variety of static and dynamic assessments. Use PKMAS for recording and analyzing balance, gait initiation, straight-away walking, gait with anomalies, running, jumping, and turning.

PKMAS Software Functions

PKMAS proprietary software functions with the ProtoKinetics Zeno Walkways as well as with the Platinum Plus GAITRite™ carpets. The PKMAS system facilitates data collection and analysis for static and dynamic balance and gait tests on these electronic walkways. After data collection, easily review the collected data and videos, alongside custom visuals and temporal, spatial, and pressure values.

PKMAS Software Measurements

PKMAS measurements include, but are not limited to: instantaneous COP, integrated pressure, COMe, step/stride length, swing/stance time, velocity, toe in/out, cadence, and path efficiency. Statistical data for the gait measurements include sample size, mean, left/right ratios, standard deviation, and coefficient of variation. PKMAS data, subject and trial details, raw walkway data, and PKMAS calculations, can be easily exported to text or Excel spreadsheet.

“Objective gait data can demonstrate a clinical significance where patient reports, observation and exams mark no change. Quantitative measurements identify significant improvements in gait and function. This computerized non-invasive gait technology allows us to care for patients more effectively and open the door to additional treatment options.”

– Dr. Mark Gudesblatt, M.D.

Gymnastics on the Zeno using PKMAS (video only – no audio)

Watch as an amateur gymnast does various maneuvers on a Zeno walkway. First he does a handstand followed by walking while in the handstand, then a forward handspring, a cartwheel, a back roll, and a stationary jump (both normal and half speed playback).  The PKMAS software shows every point of contact while tracking the COP and COMe data from the Zeno walkway.
