Relative and Absolute Reliability of a Motor Assessment System Using KINECT® Camera

Abstract

(1) Background: Virtual reality is currently useful in different clinical specialties as a diagnostic and therapeutic tool. In this study, we analyzed the relative and absolute reliability of the motor evaluation with the Kinect camera, a markerless motion system. (2) Methods: Observational study in healthy people, whose inclusion criteria were: healthy people, age 18 to 40 years old without pathologies or injuries in osteoarticular structures or ligamentous muscle and pharmacological treatment with influence on motor skills. Fifty-two subjects were evaluated. (3) Results: The results of the relative reliability were favorable in variables such as the amplitude of passage of the right leg (ICC (Intraclass Correlation Coefficient) = 0.95 ± 0.03), the step width of the left leg (ICC = 0.92 ± 0.04) or balance of the left leg (ICC = 0.90 ± 0.05). Moderate values were found for other variables. The absolute reliability, measured by the coefficient of variation, was favorable in most of the variables. (4) Conclusions: The results reflect a favorable intraclass correlation in the evaluation of the variation and asymmetry of movements of the upper limbs, the balance of both legs, the side step width and the evaluation of the sitting and standing positions. The reliability of the evaluation of the variation of movements and the asymmetry of the lower limbs must be further improved.

Model for the Detection of Falls with the Use of Artificial Intelligence as an Assistant for the Care of the Elderly

“…The first component is the area to be monitored. This work, being focused on the monitoring of older adults who present physical vulnerabilities and who do not have the assistance of a person, establishes its application within a home, considered a controlled environment [37]. Therefore, the monitoring areas can be a bathroom, a living room, a room, etc.…”

Reliability Assessment of Sensory Outcome Measure a New Developed Tool for Children with Cerebral Palsy

“…Values between 0.5 and 0.75 suggest moderate reliability, 0.75 and 0.9 indicate good dependability and higher than 0.90 indicates exceptional reliability (33) . The intra-class correlation values ranged from (0.934 to 1) indicating excellent reliability (26,33) .…”

“…It was advisable to consider both the relative and absolute reliability of a measuring scale before implementing it in clinical practice. The Spearman rho (ρ) (24) was used to describe relative reliability, while SEM and MDC measurements were used for absolute dependability (15,25,26) .…”

“…The estimate of internal consistency reliability in research that is unquestionably most frequently reported is Cronbach's coefficient alpha (26) . Internal consistency of measure, often known as homogeneity, is a metric that can be used to assess an item's stability on a scale or in a measurement.…”

Automatic Markerless Motion Detector Method against Traditional Digitisation for 3-Dimensional Movement Kinematic Analysis of Ball Kicking in Soccer Field Context

“…Currently, among the tools available to examine kicking movement performance, video analysis originates the most objective and sensitive kinematic metrics, which are not always captured by only visual ratings [5]. In fact, video analysis has been used in some other research fields (e.g., animal displacement detection and analysis), as well as in a range of sports [6][7][8][9][10][11][12][13][14]. However, while ecologically valid assessment protocols using an on-field multiple-camera setup (such as high-speed action sport cameras [15]) have made it possible to record the three-dimensional and open nature of soccer kicks, flexible/reliable and boosting image processing methods are still required to provide useful information to practitioners in due time [3,16,17].…”
