Reliability and Validity of Kinect Detector for Fitness Tests and Gait Performance Analysis

To Verify the Reliability and Validity of Kinect Detector While Apply to Physical Fitness Tests and Gait Performance Analysis

Background: Depending on nature and needs, physical fitness can be divided into healthy fitness and physical fitness (also known as competitive fitness). Healthy fitness includes cardio-respiratory fitness, muscle fitness, muscular endurance, flexibility, and body composition. Physical fitness includes coordination, speed, explosiveness, balance, agility, and reaction time. Although the monitoring of fitness is very important, most of the tests need to be assisted by professionally trained fitness inspectors, so that the public who wants to regularly check their fitness status will facing a dilemma-- insufficient of inspectors. In the face of such a situation, the somatosensory detector may be a choice which is relatively objective, convenient and no need to rely on the inspectors. Therefore, the validity and retest reliability of the somatosensory detector need to be verified in order to achieve accurate and objective measurement results.

Background: Depending on nature and needs, physical fitness can be divided into healthy fitness and physical fitness (also known as competitive fitness). Healthy fitness includes cardio-respiratory fitness, muscle fitness, muscular endurance, flexibility, and body composition. Physical fitness includes coordination, speed, explosiveness, balance, agility, and reaction time. Although the monitoring of fitness is very important, most of the tests need to be assisted by professionally trained fitness inspectors, so that the public who wants to regularly check their fitness status will facing a dilemma-- insufficient of inspectors. In the face of such a situation, the somatosensory detector may be a choice which is relatively objective, convenient and no need to rely on the inspectors. Therefore, the validity and retest reliability of the somatosensory detector need to be verified in order to achieve accurate and objective measurement results.

Research purposes: To verify the retest reliability and validity of the somatosensory detector on physical fitness and gait performance.

Methods: The trial will enroll 60 subjects, 30 of them were healthy individuals between the ages of 20 and 65, and 30 are healthy elderly than 65 years of age. The exclusion criteria including: (1) those who are unable to follow the instructions and who have orthopedic, nervous system or cardiopulmonary system disorders, or who have abnormal gait pattern, or who are affected by the above physiological system disorders. Subjects will receive two tests, there's a one-week interval between each test. In the first test, the fitness assessment of the fitness inspector and the somatosensory detector was performed simultaneously, and the fitness evaluation of the somatosensory detector was performed only for the second time. And use statistical software to analyze the reliability and validity of the somatosensory detector.

Statistical Analysis: Using SPSS 20.0 for data archiving and statistical analysis, the reliability and validity of the test will be detected by intraclass correlation one-way random model, and presenting by the intraclass correlation coefficient and 95% confidence interval.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Gait speed	Gait speed is calculated using distance in meters and time in seconds.	Change from baseline at one week
Gait cadence	Cadence is the rate at which a person walk, expressed in steps per minute.	Change from baseline at one week
Gait stride length	The stride length is the distance between two successive placements of the same foot.	Change from baseline at one week

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
One leg standing test	To test balance ability	Change from baseline at one week
Functional forward reach test	To test functional balance performance	Change from baseline at one week
Timed up and go test	To test functional balance performance	Change from baseline at one week
Upper arm curl test	To test functional muscle strength of upper extremities	Change from baseline at one week
30 seconds sit-stand-sit test	To test functional muscle strength of lower extremities	Change from baseline at one week
2 minutes stepping test	To test cardiopulmonary ability	Change from baseline at one week
