Context: Deficits in the hip range of motion are associated with hip and groin injuries. Accurate and reliable goniometric measurements are important in identifying those at risk of injury and determining the efficacy of treatment interventions. Smartphone goniometric applications are regularly used to assess joint ranges of motion; however, there is limited knowledge on the reliability of this method in relation to the hip, particularly between clinicians with different levels of experience. Objective: To determine the intratester and intertester reliability of a smartphone clinometer application for the assessment of hip goniometric measurements in healthy volunteers by an experienced and novice clinician. Design: Reliability study. Setting: University Athletic Therapy facility. Participants: Physically active, university students. Main Outcome Measures: The study determined the intra- and intertester (experienced vs novice clinician) reliability of goniometric measurements of the hip joint (modified Thomas test and seated hip internal and external rotation) using a smartphone goniometric application. Intraclass correlation coefficients (ICCs), standard error of measurement, and minimal detectable change at a 95% confidence interval were used to assess reliability. Results: Goniometric measurements demonstrated good to excellent relative intratester reliability for the modified Thomas test (ICC = .94), external rotation (ICC = .93–.95), and internal rotation (ICC = .80–.81). Intertester reliability for expert and novice clinicians was also excellent for the modified Thomas test (ICC = .98), external rotation (ICC = .95), and internal rotation (ICC = .92). Intratester and intertester standard error of measurement and minimal detectable change at 95% confidence interval values were similar for both testers and ranged from 1.9° to 3.6° and 5° to 10.1° and from 1.1° to 2.3° and 2.9° to 6.5°, respectively. Conclusion: Smartphone-based goniometric measurements of hip range of motion have high intratester and intertester reliability for novice and expert clinicians. It may be a useful, simple, and inexpensive resource for clinicians.

Background Self-report measures for assessing specific fear of activities have not been reported in the peer-reviewed literature, but are necessary to adequately test treatment hypotheses related to fear-avoidance models. Objective This study described psychomotor properties of a novel self-report measure, the Fear of Daily Activities Questionnaire (FDAQ). Design A prospective cohort design was used. Methods Reliability and validity cohorts were recruited from outpatient physical therapy clinics. Analyses for the reliability cohort included internal consistency and 48-hour test-retest coefficients, as well as standard error of measurement and minimal detectable change estimates. Analyses for the validity cohort included factor analysis for construct validity and correlation and multiple regression analyses for concurrent and predictive validity. Four-week responsiveness was assessed by paired t test, effect size calculation, and percentage of patients meeting or achieving MDC criterion. Results The FDAQ demonstrated adequate internal consistency (Cronbach alpha=.91, 95% confidence interval=.87–.95) and 48-hour test-retest properties (intraclass correlation coefficient=.90, 95% confidence interval=.82–.94). The standard error of measurement for the FDAQ was 6.6, resulting in a minimal detectable change of 12.9. Factor analysis suggested a 2- or 3-factor solution consisting of loaded spine, postural, and spinal movement factors. The FDAQ demonstrated concurrent validity by contributing variance to disability (baseline and 4 weeks) and physical impairment (baseline) scores. In predictive validity analyses, baseline FDAQ scores did not contribute variance to 4-week disability and physical impairment scores, but changes in FDAQ scores were associated with changes in disability. The FDAQ scores significantly decreased over a 4-week treatment period, with an effect size of .86 and 55% of participants meeting the minimal detectable change criterion. Limitations The validity cohort was a secondary analysis of a clinical trial, and additional research is needed to confirm these findings in other samples. Conclusions The FDAQ is a potentially viable measure for fear of specific activities in physical therapy settings. These analyses suggest the FDAQ may be appropriate for determining graded exposure treatment plans and monitoring changes in fear levels, but is not appropriate as a screening tool.

OBJECTIVE: The present study aimed to estimate the reliability, standard error of measurement (SEM), and minimum detectable change (MDC) of the star excursion balance test (SEBT) in children with cerebral palsy (CP). METHODS: Eight children with CP (five boys and three girls, sixteen legs) participated in this study. Each child carried out the SEBT and was assessed by two examiners. To determine intra-rater reliability, the intra-class correlation coefficient (ICC) model (3, 3) was calculated. To determine the inter-rater reliability, the ICC model (2, 3) was computed. RESULTS: In terms of the intra-rater reliability of the SEBT, the ICC varied from 0.98 to 0.99 and the total ICC score was 0.99 (p< 0.001). For the inter-rater reliability, the ICC varied from 0.98 to 1.00 and the total ICC score was 0.99 (p< 0.001). The SEBT had an SEM of 2.63 and an MDC of 7.31. CONCLUSION: The SEBT is not only reliable with a small SEM, but is also a simple and cheap assessment of dynamic balance in children with CP.
