Rotation Function

Background: Our group previously developed an upper extremity repositioning (Sup-ER) protocol for brachial plexus birth injuries (BPBIs) that may improve supination and external rotation (ER) at 2 years of age. Questions were raised about the potential for the protocol to cause internal rotation (IR) deficits. The goal of this study was to explore the longer-term outcomes of the Sup-ER protocol and investigate IR/ER function. Methods: This prospective cross-sectional cohort study examined 16 children older than 4 years of age with significant enough BPBI to be treated with the Sup-ER protocol. Total shoulder and elbow function were assessed, including passive and active ranges of motion and strength of IR and ER. Results: Range of motion (ROM) for most active movements was decreased in the affected compared to unaffected arm. Notably, IR passive ROM was similar in the affected (78.7°) and unaffected arm (82.8°). External rotation strength of the affected arm was weaker (42.8 N) compared to the unaffected arm (57.9 N). IR strength had a greater deficit in the affected (43.2 N) arm compared to the unaffected arm (72.2 N), but both ER and IR showed less deficit than described in the literature. Conclusions: Despite differences in ranges of motion between the affected and unaffected arms, ROMs for the affected arm were comparable to the functional limits as reported in the literature. The Sup-ER protocol shows potential to optimize long-term shoulder rotation function in children with BPBI without compromising IR.

AbstractUltimate Frisbee is a team sport where players mainly use their dominant arm for throwing a flying disc. Little is known about possible functional adaptations to this unilateral strain. The purpose of this study was to investigate shoulder rotation strength and range of motion (ROM) in elite Ultimate Frisbee players. We were especially interested in possible sport-specific functional adaptations of peak torque and work ratios as well as the range of motion of agonist and antagonist shoulder rotators regarding laterality between the dominant and non-dominant body sides. For this reason, the concentric external and internal isokinetic (60°/s) shoulder rotation torque and passive glenohumeral rotation ROM were examined in 15 male subjects (27.5 ± 5.5 yrs; all current or former members of the German National Team) and comparisons of dominant to non-dominant body sides were conducted. Maximum strength (work) during external shoulder rotation was higher on the dominant body side compared with the non-dominant body side (8.4 ± 8.4 %; p < 0.01). No side-to-side differences were found in maximum internal rotation strength. Internal rotation ROM and total ROM were smaller on the dominant body side (21 ± 18 %; p < 0.01 and 5 ± 9 %; p < 0.05). Our findings indicate similar adaptation patterns of shoulder rotation mobility compared to other overhead sports, but differing results regarding shoulder rotation strength. Stretching exercises and monitoring programs are recommended for elite Ultimate Frisbee players, starting at the early stages of the career.

Background In clinical practice range of motion (RoM) is usually assessed with low-cost devices such as a tape measure (TM) or a digital inclinometer (DI). However, the intra- and inter-rater reliability of typical RoM tests differ, which impairs the evaluation of therapy progress. More objective and reliable kinematic data can be obtained with the inertial motion capture system (IMC) by Xsens. The aim of this study was to obtain the intra- and inter-rater reliability of the TM, DI and IMC methods in five RoM tests: modified Thomas test (DI), shoulder test modified after Janda (DI), retroflexion of the trunk modified after Janda (DI), lateral inclination (TM) and fingertip-to-floor test (TM). Methods Two raters executed the RoM tests (TM or DI) in a randomized order on 22 healthy individuals while, simultaneously, the IMC data (Xsens MVN) was collected. After 15 warm-up repetitions, each rater recorded five measurements. Findings Intra-rater reliabilities were (almost) perfect for tests in all three devices (ICCs 0.886–0.996). Inter-rater reliability was substantial to (almost) perfect in the DI (ICCs 0.71–0.87) and the IMC methods (ICCs 0.61–0.993) and (almost) perfect in the TM methods (ICCs 0.923–0.961). The measurement error (ME) for the tests measured in degree (°) was 0.9–3.3° for the DI methods and 0.5–1.2° for the IMC approaches. In the tests measured in centimeters the ME was 0.5–1.3cm for the TM methods and 0.6–2.7cm for the IMC methods. Pearson correlations between the results of the DI or the TM respectively with the IMC results were significant in all tests except for the shoulder test on the right body side (r = 0.41–0.81). Interpretation Measurement repetitions of either one or multiple trained raters can be considered reliable in all three devices.

BACKGROUND: The detection of primary risk factors through the assessment of shoulder range of motion (ROM) and muscle function could prevent injuries in the initial stages of the handball (HB) practice. OBJECTIVE: To compare shoulder ROM, muscle strength and muscle extensibility between throwing and non-throwing shoulders in young HB athletes and between non-HB athletes. METHODS: A cross-sectional study was designed. Participants aged between 14–16 years that practice physical activity regularly were included and divided in two groups. The HB group included volunteers who practiced HB, the control group included volunteers who practiced other activities. The variables measured were internal rotation and external rotation ROM, maximum isometric strength, and extensibility of the tissues of the posterior part of the throwing and non-throwing shoulder. RESULTS: Thirty-seven subjects were included. The HB group (n= 19) showed greater ROM in both shoulders compared to the control group (n= 18) (p< 0.05). The throwing shoulder of the HB group showed less internal rotation ROM, greater external rotation ROM and greater internal rotation strength when compared to the non-throwing shoulder (p< 0.05). CONCLUSIONS: The results of the study suggest that young HB athletes present differences in shoulder ROM compared to non-HB athletes. Also, HB athletes showed differences in ROM and strength between the TS and non-TS. Hence, the assessment of the shoulder ROM and muscle function should be taken into consideration to avoid injuries in this population.

BACKGROUND In recent years, different smartphone apps have been validated for joint goniometry, but none for goniometric assessment of gait after stroke. OBJECTIVE The aims of our work were to assess:1) to assess intra-rater reliability of an image-based goniometric app – DrGoniometer- in the measurement of the extension, flexion angles and range of motion of the knee during the hemiparetic gait of a stroke patient; (2) its validity comparing to the reference method (electrogoniometer) for flexion-extension excursion measurements; and the intra-rater agreement in the choice of the video frames. METHODS An left-hemiparetic inpatient following haemorrhagic stroke was filmed using the app while walking on a linear path. An electrogoniometer was fixed on the medial face of the affected knee in order to record the dynamic goniometry during gait. Twenty-one raters, blinded to measurements, were recruited to rate knee angle measurements from video acquired with DrGoniometer. Each rater repeated the same procedure twice, the second one at least one day after the first measure. RESULTS Results showed that flexion angle measurements are reliable (ICC95%=0.66, 0.34;0.85; SEM=4°), and adequately precise (CV=14%). Extension angles measurements demonstrated moderate reliability and higher degree of variation (ICC=0.51, 0.09;0.77; SEM 4°; CV=53%). ROM values were: ICC=0.23 (-0.21;0.60); CV=20%. Accuracy of DrGoniometer compared to the electrogoniometer was 7.3±4.7°. The selection of maximum extension frame revealed an accordance of 58% and 72% within a range of ±5 or ±10 frames, respectively; while the best flexion frame reported 86% of agreement for both range of 5 and 10 frames. CONCLUSIONS The results demonstrated moderate to good reliability concerning the maximum extension and flexion angles, while assessing ROM DrGoniometer showed poor intra-rater reliability. Flexion angle measurements seemed to be reliable according to ICC and SEM values and more precise with a limited dispersion of results DrGoniometer revealed a good accuracy in the measurement of range of motion. The agreement of the maximal extension frame was anyway adequate within 5 frames (59%) and noticeably increased within 10 frames (72%). In conclusion, DrGoniometer was found to be a valid and reliable method for assessing knee angles during hemiparetic gait. Further studies are necessary to investigate inter-rater reliability and confirm our results.
