Nevertheless, for optimum results an angle of 90° is suggested.

The results thus obtained indicate that the Kinovea software is a valid and reliable tool that is able to measure accurately at distances up to 5 m from the object and at an angle range of 90°–45°. To evaluate Kinovea reliability and validity a multiple approach was applied involving the following analysis: -systematic error with a two-way ANOVA 2x4 -relative reliability with ICC and CV (95% confidence interval) -absolute reliability with Standard Error. For each export data item, 20 angles and 20 distance variables were calculated, with intra- and inter-observer reliability also analysed. Each frame was examined by three observers who each made two attempts. For this purpose, a figure with 29 points was designed (in AutoCAD) and 24 frames analysed. The main objective of this study was to determine the validity and reliability of the Kinovea software in obtaining angular and distance data at different perspectives of 90°, 75°, 60° and 45°. Although it has been validated as a tool with which to assess time-related variables, this is not yet the case regarding angular and distance variables. I have been working on this project in some shape or form since 2004, and I'm blown away that over the years it has been downloaded more than a million times, used by thousands of athletes, coaches, students, physical therapists and. Kinovea is supported by users via Patreon.
Hi, I'm Joan Charmant, creator and developer of Kinovea. This low-cost technology has been used in sports sciences, as well as clinical field and research work. Kinovea is a video player for sport analysis.

Kinovea © is a free 2D motion analysis software that enables the establishment of kinematics parameters. The integrated file explorer lets you browse your video collection visually. In addition to this primary focus, Kinovea is also used by animation artists, podiatrists, and ergonomics engineers. It is mostly used by sports coaches and athletes to explore, study or comment a performance. The proposed system has the potential to provide accurate segment angles and peak GRF at low cost but does not match the accuracy of the multicamera system and force platform, in part because of the Wii Balance Board’s variable sampling rate.Clinical rehabilitation and sports performance analysis both require the objectification of movement. Kinovea is a free and open source solution for video analysis. Uses of Kinovea Observe and Show Compare Measure Extend. User Guide for Kinovea CREATED BY: KEVIN THOMAS CHRISTINA BOWEN RONDA WHYTE. The thigh, shank, and foot angle measurements were similar between the single and multicamera, but the pelvis angle was far less accurate. User Guide for Kinovea CREATED BY KEVIN THOMAS. Kinovea 0.8.15 (, France) was used for analysis. However, variability in the balance board’s sampling rate led to large GRF errors early and late in stance, when the GRF changed rapidly. first 1.2 s of movement in situ on a BMX SX ramp using a standard gate start procedure. Average GRF data from the 2 systems were similar, with peak GRF errors below 3.5%BW.
We collected vertical GRF and segment angles. After validation trials with known weights and angles, 5 subjects walked across an instrumented walkway for multiple times (n = 8/subject). We validated this low-cost system against a multicamera Vicon system and research-grade force platform (Advanced Mechanical Technology, Inc).
The purpose of this study was to validate a Wii Balance Board, Kinovea motion-tracking software, and a video camera as a portable, low-cost system, and overground gait analysis system. However, it is inconvenient and expensive to maintain a laboratory-grade gait analysis system in most clinics.
Clinically, measuring gait kinematics and ground reaction force (GRF) is useful to determine the effectiveness of treatment.
