Exercise-Induced Tendon and Bone Injury in Recreational Runners: A Test-Retest Reliability Study

Exercise-Induced Tendon and Bone Injury in Recreational Runners: A Test-Retest Reliability Study

Several questions from the tail end of the survey were also selected to assess if respondent fatigue had an effect on reliability. To approach this experimentally, we used a test-retest reliability design.

Reliability of Self-Reported Mobile Phone Ownership in Rural North-Central Nigeria: Cross-Sectional Study

Reliability of Self-Reported Mobile Phone Ownership in Rural North-Central Nigeria: Cross-Sectional Study

In the light of this work, the mobile phone, which is ubiquitous, will play a key role in furthering these objectives [21].There is, however, limited evidence of the reliability of self-reported mobile phone ownership and access, which may be affected by various

Using Smart Bracelets to Assess Heart Rate Among Students During Physical Education Lessons: Feasibility, Reliability, and Validity Study

Using Smart Bracelets to Assess Heart Rate Among Students During Physical Education Lessons: Feasibility, Reliability, and Validity Study

The total values for interdevice reliability were evaluated at two running speeds and the devices demonstrated good reliability (ICC=0.99 [95% CI 0.99-0.99]; MD=0.05 [SEM 0.03]; MAPE=1.43% [SD 1.67]).

Comparison of a Mobile Health Electronic Visual Analog Scale App With a Traditional Paper Visual Analog Scale for Pain Evaluation: Cross-Sectional Observational Study

Comparison of a Mobile Health Electronic Visual Analog Scale App With a Traditional Paper Visual Analog Scale for Pain Evaluation: Cross-Sectional Observational Study

In order to improve reliability coefficients, 95% CIs were calculated from the estimated sum of squares. For both intermethod reliability and intramethod reliability, the ICCs were higher than 0.8.
