Objectives: To assess the temporal differentiation of activity of gluteus minimus and the deep and the superficial regions of gluteus medius during weight bearing and non-weight bearing exercises. Design: Repeated measures design on a single recording occasion. Method: M-mode ultrasound was used to capture activity-related muscle motion of the gluteus minimus and medius muscles in 20 healthy volunteers during weight shift, hip hitch, side-lying abduction and active leg lengthening exercises. M-mode traces were computer-processed for detecting muscle motion onsets. Mean onset differences between muscle regions and their intra-individual variability were assessed. Results: In contrast to side-lying abduction, the weight shift and hip hitch exercises resulted in larger onset variability between the gluteus minimus and deep gluteus medius (P < 0.001) and also between the deep and superficial regions of the gluteus medius (P < 0.05). Conclusions: Weight bearing exercises promoted a greater functional differentiation between deep and superficial hip abductor muscles. (C) 2015 Elsevier Ltd.

OBJECTIVE: To evaluate spine kinematics and gait characteristics in people with nonspecific chronic neck pain. BACKGROUND: People with chronic neck pain present with a number of sensorimotor and biomechanical alterations, yet little is known about the influence of neck pain on gait and motions of the spine during gait. METHODS: People with chronic nonspecific neck pain and age- and sex-matched asymptomatic controls walked on a treadmill at 3 different speeds (self-selected, 3 km/h, and 5 km/h), either with their head in a neutral position or rotated 30. Tridimensional motion capture was employed to quantify body kinematics. Neck and trunk rotations were derived from the difference between the transverse plane component of the head and thorax and thorax and pelvis angles to provide an indication of neck and trunk rotation during gait. RESULTS: Overall, the patient group showed shorter stride length compared to the control group (P<.001). Moreover, the patients with neck pain showed smaller trunk rotations (P<.001), regardless of the condition or speed. The difference in the amount of trunk rotation between groups became larger for the conditions of walking with the head rotated. CONCLUSION: People with chronic neck pain walk with reduced trunk rotation, especially when challenged by walking with their head positioned in rotation. Reduced rotation of the trunk during gait may have long-term consequences on spinal health."],["dc.identifier.doi","10.2519/jospt.2017.6768"],["dc.identifier.isi","000398334200007"],["dc.identifier.pmid","28158961"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42920"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","J O S P T"],["dc.relation.issn","1938-1344"],["dc.relation.issn","0190-6011"],["dc.title","People With Chronic Neck Pain.

However, individual variation in the muscle shear modulus obscures differences between healthy and diseased individuals. Normalization may improve the comparability between individuals. The shear modulus at different functional tasks served as a reference for normalizing the neck muscles’ shear modulus of 38 women, 20 with chronic neck pain and 18 asymptomatic. Reference tasks were maximal voluntary contraction, relaxed sitting, prone head lift, balancing 1 kg on the head, and neck extension at 48 N. The effects of normalization on within-group variation and between-group differences were compared. Normalization with maximal voluntary contraction was discarded due to imaging problems. Normalization with relaxed sitting, prone head lift, balancing 1 kg, and neck extension at 48 N reduced within-group variation, by 23.2%, 26.8%, 11.6%, and 33.6%, respectively. All four normalization approaches reduced the p-values when testing for between-group differences. For the pain group, normalization with relaxed sitting and head lift indicated less normalized muscle stiffness, while normalization with balancing 1 kg and extension at 48 N indicated higher stiffness. The contradictory results are explainable by non-significant group differences in the reference tasks. Normalization of the muscle shear modulus is effective to reduce within-group variation, but a trustworthy normalization approach for group comparisons has yet to be identified."],["dc.description.sponsorship","Baden-Württemberg Ministry of Science, Research and Culture"],["dc.description.sponsorship","Institute of Applied Research of Furtwangen University"],["dc.identifier.doi","10.3390/diagnostics12081791"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/112634"],["dc.language.iso","en"],["dc.relation.eissn","2075-4418"],["dc.rights","CC BY 4.0"],["dc.title","Assessment of Neck Muscle Shear Modulus Normalization in Women with and without Chronic Neck Pain"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

To evaluate this, ten healthy men performed isometric elbow flexion at 20% to 70% of their maximal force.

The time intervals between automated and visually estimated activation onsets were correlated with the regional variation of EMG and muscle motion onset, contraction level and speed.

Traction and compression, 2. Resistance applied in either flexion or extension at the occiput, at the level of the vertebral arch of Cl and of C4, and 3. Maintaining the neck in neutral while inclined on the elbows, with and without resistance at C4. The ratio between semispinalis cervicis and the splenius capitis EMG amplitude was quantified as an indication of whether the exercise could emphasize the activation of the semispinalis cervicis muscle relative to the splenius capitis. Manual resistance applied in extension over the vertebral arch emphasized the activation of the semispinalis cervicis relative to the splenius capitis at the spinal level directly caudal to the site of resistance (ratio: 2.0 +/- 1.1 measured at C5 with resistance at C4 and 2.1 +/- 1.2 measured at C2 with resistance at Cl).

The objective of this study was to create a German, culturally-adapted version of the CSI and to test its psychometric properties.\r\n \r\n \r\n Methods\r\n A German version of the CSI (CSI-GE) was developed, culturally-adapted, and pretested for comprehensibility. The psychometric properties of the resulting version were validated in a clinical study with chronic pain and pain-free control subjects. To assess retest reliability, the CSI-GE was administered twice to a subgroup of patients. Structural validity was tested using factor analyses. To investigate construct validity a hypotheses testing approach was used, including (1) correlations between the CSI-GE and several other well-established questionnaires as well as (2) an investigation of the CSI-GE discriminative power between different subgroups of participants believed to have different degrees of CS.\r\n \r\n \r\n Results\r\n The CSI-GE showed excellent reliability, including high test-retest characteristics. Factor analyses confirmed a bi-factor dimensionality as has been determined previously. Analysing construct validity 6 out of 11 hypotheses (55%) were met. CSI-GE scores differentiated between subgroups according to expectations. Correlations between CSI-GE scores and other questionnaires suggested that none of the correlated constructs was identical, but there was overlap with other questionnaires based on symptom load. Several correlations did not fit with our current understanding of CS.\r\n \r\n \r\n Conclusion\r\n The CSI-GE appears to be a reliable tool for measuring CS/CSS-related symptomatology.
