Hip Rotation

Context: Hip rotation range of motion (ROM) is commonly assessed in individuals with lower extremity or spine pathology. It remains unknown which hip rotation ROM testing position is most reliable. Objective: To compare interrater and intrarater reliabilities between hip internal rotation (IR) and external rotation (ER) ROM in supine and seated positions. Study Design: Controlled laboratory study. Setting: University research laboratory. Participants: A total of 19 participants (11 females and 8 males; age = 23.5 [1.2] y; height = 173.2 [8.6] cm; and mass = 69.2 [13.4] kg) without hip, knee, low back, or sacroiliac pain within the preceding 3 months or history of hip or low back surgery were recruited. Interventions: Three testers obtained measures during 2 testing sessions. Passive supine and seated hip IR and ER ROM were performed with the hip and knee flexed to 90°. Main Outcome Measures: The primary outcome measures were hip IR and ER ROM in supine and seated positions (in degrees). Interrater and intrarater reliabilities were calculated using intraclass correlation coefficients (ICCs). Minimal detectable change was calculated. Differences between supine and seated hip IR and ER ROM values were assessed using paired t tests (significance level was .05). Results: Supine hip IR and ER ROM interrater and intrarater reliabilities were excellent (ICC = .75–.91). Seated hip IR ROM interrater and intrarater reliabilities were good (ICC = .64–.71). Seated hip ER ROM interrater reliability was good (ICC = .65), and intrarater reliabilities were good to excellent (ICC = .65–.82). Minimal detectable change values for supine and seated hip IR and ER ROM ranged from 6.1° to 8.6°. There were significant differences between supine and seated positions for hip IR and ER ROM (41.6° vs 44.5°; P < .01 and 53.0° vs 44.2°; P < .01, respectively). Conclusion: Supine hip rotation had higher interrater and intrarater reliabilities. Hip IR and ER ROM values differed significantly between supine and seated positions and should not be used interchangeably.

Background: Cricket bowling involves combined spinalmovements of side bending and rotation and, consequently, injuryto the low back is a common problem. Therefore the assessmentof lumbar spine kinematics has become a routine component inpreseason screening. This includes static measurement of lateralspinal flexion as asymmetrical range of motion may predispose anathlete to low back injury.Objectives: This study examined intra-rater reliability andconcurrent validity of the fingertip-to-floor distance test (FFD)when compared to a criterion range of motion measure.Methods: Thirty-four junior-level cricket players aged 13‑16years were recruited. Lumbar spine lateral flexion was measuredsimultaneously with the fingertip-to-floor distance test and digitalinclinometry methods. Relative and absolute intra-rater reliabilitywere investigated with intraclass correlation coefficients (ICC3,1)of agreement, standard error of measurement (SEM) estimates,Bland and Altman bias estimates and 95% limits of agreement,respectively. The concurrent validity of the fingertip-to-floordistance test, compared to digital inclinometry measures, wasexamined with Pearson correlation coefficients.Results: Intra-rater reliability demonstrated substantial agreementfor both measures (ICC3,1 > 0.84). The fingertip-to-floor distancetest SEM values ranged from 1.71‑2.01 cm with an estimatedminimum detectable change (MDC) threshold of 4.73‑5.55 cm.The inclinometry SEM values ranged from 1.00‑1.09° withminimal detectable change estimates of 2.77‑3.01°. There werestrong correlations between the index test and criterion measureoutcomes (r > 0.84, p < 0.001).Conclusions: This study’s results support the intra-rater reliabilityand concurrent validity of the finger-to-floor distance test,suggesting it to be a suitable surrogate measure for lumbar lateralflexion testing

Background and Purpose Three-dimensional kinematic analysis of reaching has emerged as an evaluative measure of upper-extremity motor performance in people after stroke. However, the psychometric properties supporting the use of kinematic data for evaluating longitudinal change in motor performance have not been established. The objective of this study was to determine, in a test-retest reliability manner, the reproducibility and minimal detectable change for reaching kinematics in people after stroke. Subjects and Methods Fourteen participants with hemiparesis after stroke performed forward reaching tasks on 2 occasions 37.3 (SD=9.8) days apart. At each session, participants performed 4 forward reaching tasks produced by the combination of 2 target heights (low and high [109 and 153 cm from the floor, respectively]) and 2 instructed movement speeds (self-selected and as fast as possible). Two analytical methods were used to calculate kinematic parameters. Results Relative reliability (intraclass correlation coefficient) ranged from .04 to .99, and absolute reliability (standard error of measurement) ranged from 2.7% to 76.8%, depending on the kinematic variable, the demands of the motor task (target height and movement speed), and the analytical method. Bland-Altman analysis, a statistical method used to assess the repeatability of a method, revealed few systematic errors between sessions. The minimal detectable change ranged from 7.4% to 98.9%. Discussion and Conclusion Depending on the demands of the motor task and the analytical method, most kinematic outcome measures (such as peak hand velocity, endpoint error, reach extent, maximum shoulder flexion range of motion, and minimum elbow extension range of motion) are reliable measures of motor performance in people after stroke. However, because of the magnitude of within-subject measurement error, some variables (such as peak hand velocity, time to peak hand velocity, and movement time) must change considerably (&gt;50%) to indicate a real change in individual participants. The results of our reliability analysis, which are based on our cohort of participants with hemiparesis after stroke and our specific paradigm, may not be generalizable to different subpopulations of people with hemiparesis after stroke or to the myriad movement tasks and kinematic variables used for the assessment of reaching performance in people after stroke.

Hip Rotation

Context:Currently, hip-rotation range of motion (ROM) is clinically measured in an open kinetic chain in either seated or prone position using passive or active ROM. However, during activities of daily living and during sports participation the hip must be able to rotate in a loaded position, and there is no standard measurement for this.Objective:To determine if a novel method for measuring hip rotation in weight bearing will result in good to very good reliability as demonstrated by an intraclass correlation coefficient (ICC) of >.80 and to investigate if weight-bearing hip measurements will result in significantly reduced hip ROM compared with non-weight-bearing methods.Design:Repeated measures.Setting:Outpatient sports physical therapy clinic.Participants:20 healthy participants (10 men, 10 women) recruited for hip-rotation measurements.Methods:Three trials of both internal and external rotation were measured in sitting, prone, and weight bearing. Two therapists independently measured each participant on the same day. The participants returned the following day to repeat the same measurements with the same 2 therapists.Main Outcome Measures:Degrees of hip internal and external rotation measured in prone, sitting, and loaded positions.Results:In general, the measurement of hip ROM across the different conditions was reliable. The intrarater reliability was .67–.95, while interrater reliability was .59–.96. Interrater reliability was improved when values were averaged across the measures (.75–.97). ICCs for active loaded ROM were .67–.81, while interrater ICCs were .53–.87. In general, prone hip ROM was greater than supine and supine was greater than loaded.Conclusions:Loaded hip rotation can be measured in a clinical setting with moderate to good reliability. The rotation ROM of a loaded hip can be significantly decreased compared with unloaded motion.

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.

Objectives Three-dimensional gait analysis has been recommended as part of standardized gait assessment in people with spinal cord injury. The aim was to investigate inter- and intra-session reliabilities of gait kinematics in people with spinal cord injury. Methods Fifteen adults with spinal cord injury performed two test sessions on separate days. Six infrared cameras, 16 reflective markers and the Plug-in gait model were used. For each subject, five gait trials from both sessions were included. The Gait Profile Score and the Gait Variable Score were used as kinematic outcome measures. Reliability was assessed with intraclass correlation coefficient, standard error of measurement, minimal detectable change, and Bland–Altman plots. Results Inter-session intraclass correlation coefficient for all variables was >0.82 and standard error of measurement <1.8°, except for hip rotation. Intra-session reliability was found to be high (≥0.78) and slightly better than that for inter-session. Minimal detectable change for all variables was <4.7°, except for hip rotation. Conclusions The high inter- and intra-session reliabilities indicate small intrinsic variation of gait. Thus, three-dimensional gait analysis seems to be a reliable tool to evaluate kinematic gait in adults with spinal cord injury, but caution is warranted especially for hip rotation evaluation.

Cross Cultural Adaptation

BACKGROUND: Illness perceptions predict chronic low back pain (CLBP) disability. This study cross-culturally adapted and validated the Igbo Brief Illness Perceptions Questionnaire (Igbo-BIPQ) in people with CLBP in rural/urban Nigeria. METHODS: A cross-cultural adaptation and validation of the Igbo-BIPQ was undertaken. The BIPQ was forward/back-translated by clinical/non-clinical translators. An expert review committee appraised the translations. The questionnaire was pre-tested on twelve rural Nigerian dwellers with CLBP. Internal consistency using Cronbach’s alpha; test-retest reliability using intra-class correlation coefficient and Bland-Altman plot; and minimal detectable change were investigated amongst 50 people with CLBP in rural and urban Nigeria. Construct validity was determined by correlating the Igbo-BIPQ score with those of eleven-point box scale and Igbo Roland Morris Disability Questionnaire (Igbo-RMDQ) using Pearson’s correlation analyses in 200 adults with CLBP in rural Nigeria. Ceiling and floor effects were investigated in both samples. RESULTS: Good face/content validity, internal consistency (α= 0.76) and intraclass correlation coefficient (ICC = 0.78); standard error of measurement and minimal detectable change of 5.44 and 15.08 respectively; moderate correlations with pain intensity and self-reported disability (r⩾ 0.4); no ceiling/floor effects were observed for Igbo-BIPQ. CONCLUSION: This study provides evidence of some aspects of validity and reliability of the Igbo-BIPQ.

Abstract Objective The mini-BESTest is a balance measure for assessment of the underlying physiological systems for balance control in adults. Evaluations of test–retest reliability of the mini-BESTest in larger samples of people with multiple sclerosis (MS) are lacking. The purpose of this study was to investigate test–retest reliability of the mini-BESTest total and section sum scores and individual items in people with mild to moderate overall MS disability. Methods This study used a test–retest design in a movement laboratory setting. Fifty-four people with mild to moderate overall MS disability according to the Expanded Disability Status scale (EDSS) were included, with 28 in the mild subgroup (EDSS 2.0–3.5) and 26 in the moderate subgroup (EDSS 4.0–5.5). Test–retest reliability of the mini-BESTest was evaluated by repeated measurements taken 1 week apart. Reliability and measurement error were analyzed. Results Test–retest reliability for the total scores were considered good to excellent, with intraclass correlation coefficients of .88 for the whole sample, .83 for the mild MS subgroup, and .80 for the moderate MS subgroup. Measurement errors were small, with standard error of measurement and minimal detectable change of 1.3 and 3.5, respectively, in mild MS, and 1.7 and 4.7, respectively, in moderate MS. The limits of agreement were − 3.4 and 4.6. Test–retest reliability for the section scores were fair to good or excellent; weighted kappa values ranged from .62 to .83. All items but 1 showed fair to good or excellent test–retest reliability, and percentage agreement ranged from 61% to 100%. Conclusions The mini-BESTest demonstrated good to excellent test–retest reliability and small measurement errors and is recommended for use in people with mild to moderate MS. Impact Knowledge of limits of agreement and minimal detectable change contribute to interpretability of the mini-BESTest total score. The findings of this study enhance the clinical usefulness of the test for evaluation of balance control and for designing individually customized balance training with high precision and accuracy in people with MS.

Abstract Introduction Static postural stability is the ability to maintain the posture with minimum sway. Increasing postural sway during standing in different sensory conditions is associated with aging due to decline in sensory and motor functions. Sway area measured by using sway meter is usually simple method for assessing postural stability in elderly subjects. Like many biological measurements, sway area has an intrinsic variability that affects their test-retest reliability and responsiveness of postural stability assessment. The minimal detectable change (MDC) is ability to detect smallest change beyond measurement error that reflects a reliable change. Therefore, the MDC value could provide information of clinical relevance on postural stability. The aims of this study were to determine test-retest reliability and MDC of sway area obtained from sway meter in elderly subjects. Methods Twelve healthy elderly subjects aged 60 years and above were participated in this study. The test and retest repeatability of postural sway measurements were performed twice with a 1-hour interval. For each subject was assess postural sway using Lord’s sway meter during standing on 4 sensory conditions for 30 seconds of each condition. The test-retest reliability of sway area was calculated using intraclass correlation coefficient. The MDC for each sway area was calculated to quantify clinical relevance. Results The test-retest reliability of sway area revealed good to excellent reliability ranged from 0.85 to 0.94. Standard error of measurement (SEM) and MDC ranged from 75 to 205 mm2 and 209 to 568 mm2, respectively. Discussion and Conclusion Our findings reveal that sway area in different sensory conditions could be used in assessment of postural stability in elderly subjects. SEM and MDC of sway area increased when subjects were asked to close their eyes and on foam surface. The sway meter is a reliable tool for assessing postural stability in clinical setting.
