Kinovea Software Versus Digital Goniometer in Measurement Range of Motion Among School Children

Abstract

Background: As part of their musculoskeletal evaluations, physiotherapists frequently measure the range of motion (ROM) of joints in both passive and active human motions, as well as in static positions.  Common tools for traditional range of motion evaluation include goniometers and inclinometers. Kinovea is a versatile and user-friendly software application that has gained popularity in measuring and analyzing ROM.

Aim: To measure (ROM) of elbow and knee joints among school children using digital goniometer and Kinovea software then compare the results of both measurements, and to investigate the internal consistency and intra-rater reliability of Kinovea software. 

Methods: This cross-sectional comparative study included 100 normal healthy children of both sexes recruited from different preparatory and secondary schools at Giza Governorate, Egypt.  Digital medical scale was used for measuring body weight, height and calculating BMI on scale screen. Baseline digital goniometer and Kinovea Computer software were used to measure ROM of knees and elbow.

Results: The mean value of BMI (kg/m2) was 21.86 ±1.67kg/m2 with minimum value 18.70 and maximum value 24.80. The number (percentage) of gender distribution categories for children were 54 (54.00%) males and 46 (46.00%) females. The statistical analysis showed no significant statistical difference (P>0.05) in elbow flexion, elbow extension, knee flexion in addition to knee extension by the both methods. There was high internal consistency and high Intra-class Correlation Coefficient of Kinovea software in measuring elbow flexion, extension, knee flexion and extension (p=0.001).

Conclusion: As there was no difference between both methods in measuring ROM in knee and elbow, it is concluded that Kinovea has the ability to provide accurate knee and elbow ROM measurements without the need for specialized training or expensive equipment makes it an accessible option for clinicians and researchers alike. Kinovea software has high internal consistency and intra-rater reliability, non-invasive, easy to use, and cost-effective tool that is coping with recent technological advancement makes it particularly suitable for pediatric populations, where cooperation and comfort are essential.
