Context:Athletes are often examined for return to sports using a functional-testing algorithm. No research has determined whether a closed kinetic chain (CKC) isokinetic testing bout influences the reliability of functional tests.Objective:To determine whether a concentric CKC isokinetic test bout alters test–retest reliability of lower extremity functional testing.Design:Subjects participated in velocity-spectrum CKC isokinetic bouts on 2 days 1 week apart.Setting:Hospital-based clinic.Participants:28 normal subjects (mean age 26.7 years, height 27.2 cm, weight 75.8 kg).Analysis and Results:Means and SDs were determined. Intraclass correlation coefficients were used to calculate test–retest reliability and between days 1 and 2 ranged from .91 to .98.Conclusions:Even after a CKC isokinetic test bout, test–retest reliability of functional tests is very high. Future research should determine test–retest reliability of functional tests for patients with lower extremity pathology.

Test Retest Reliability

Background. The Lateral Step-Up Test (LSUT) has been used to evaluate the closed kinetic chain functional muscle strength in people with orthopaedic or neurological conditions. No study has systematically investigated the intrarater, interrater, and test-retest reliabilities of this measure in stroke survivors. In addition, correlations of the LSUT count with other stroke-specific impairment and function measurements remain unidentified. Objectives. This study was aimed at investigating (1) the interrater, intrarater, and test-retest reliability of the LSUT; (2) minimum detectable change in LSUT counts; and (3) correlation between LSUT counts and stroke-specific impairment and function measurements. Methods. Thirty-three stroke survivors were assessed with LSUT and a battery of stroke-specific impairment and function measurements, including Fugl-Meyer assessment of lower extremity (FMA-LE), lower limb muscle strength, Five Times Sit-to-Stand Test (FTSTS), Berg Balance Scale (BBS), Timed Up and Go Test (TUG), and Activities-specific Balance Confidence (ABC) scale, by two assessors. Their performance on LSUT was reassessed 1 week later to establish the test-retest reliability. The intraclass correlation coefficient (ICC) was used to assess the reliability of LSUT, and Spearman’s rho was used to quantify the strength of correlations between LSUT counts and secondary outcomes. Results. The LSUT counts exhibited good to excellent intrarater, interrater, and test-retest reliability (ICC: 0.869–0.991). The minimum detectable change in the average LSUT count was 1 step. LSUT counts correlated significantly with the FMA-LE score, lower limb muscle strength (except for the hip abductors), FTSTS time, BBS score, TUG time, and ABC score. Conclusions. The LSUT is a reliable, valid, and easily administered measure of the closed kinetic chain functional muscle strength of stroke survivors.

Context:Functional testing of patients is essential to clinicians because it provides objective data for documentation that can be used for serial reassessment and progression through a rehabilitation program. Furthermore, new tests should require minimal time, space, and money to implement.Purpose:To determine the test-retest reliability of the Closed Kinetic Chain (CKC) Upper Extremity Stability Test.Participants:Twenty-four male college students.Methods:Each subject was tested initially and again 7 days later. Each subject performed 1 submaximal test followed by 3 maximal efforts. A 45-second rest was given after each 15-second test. The 2 maximal-test scores were averaged and compared with those from the retest.Results:The intraclass correlation coefficient was .922 for test-retest reliability. A paired-samplesttest (.927) was conducted, and the coefficient of stability was .859. The results indicate that the CKC Upper Extremity Stability Test is a reliable evaluation tool.

Test Retest Reliability

Ankle ligament sprains are the most common injury in soccer. The high rate of these injuries demonstrates a need for novel data collection methodologies. Therefore, soccer shoes and shin guards were instrumented with inertial sensors to measure ankle joint kinematics in the field. The purpose of this study was to assess test-retest reliability and concurrent criterion validity of a kinematic assessment using the instrumented soccer equipment. Twelve soccer athletes performed athletic maneuvers in the laboratory and field during 2 sessions. In the laboratory, ankle joint kinematics were simultaneously measured with the instrumented equipment and a conventional motion analysis system. Reliability was assessed using ICC and validity was assessed using correlation coefficients and RMSE. While our design criteria of good test-retest reliability was not supported (ICC > .80), sagittal plane ICCs were mostly fair to good and similar to motion analysis results; and sagittal plane data were valid (r = .90−.98; RMSE < 5°). Frontal and transverse plane data were not valid (r < .562; RMSE > 3°). Our results indicate that the instrumented soccer equipment can be used to measure sagittal plane ankle joint kinematics. Biomechanical studies support the utility of sagittal plane measures for lower extremity injury prevention.

Torque Development

Measuring ankle torque is of paramount importance. This study compared the test–retest reliability of the plantar flexion torque–generating capacity between older and younger men. Twenty-one older (68 ± 6 years) and 22 younger (25 ± 5 years) men were tested twice for maximal isometric plantar flexion. Peak torque (PT), rate of torque development, and contractile impulses (CI) were obtained from 0 to 50 ms (rate of torque development0–50; CI0–50) and from 100 to 200 ms (rate of torque development100–200; CI100–200). Typical error as the coefficient of variation (CVTE) and intraclass correlation coefficient were used to assess test–retest reliability. Student’s t test was applied to investigate systematic errors. The CVTE ratio was used for between-group comparisons. Only PT demonstrated acceptable reliability (intraclass correlation coefficient ≥ .75 and CV ≤ 10%). Older men demonstrated greater CVTE than younger men for PT (ratio = 2.24), but lesser for rapid torque (ratio ≤ 0.84). Younger men demonstrated systematic error for PT (6.5%) and CI100–200 (−8.9%). In conclusion, older men demonstrated greater variability for maximal torque output, but lesser for rapid torque.
