TY - JOUR A1 - Henschke, Jakob A1 - Kaplick, Hannes A1 - Wochatz, Monique A1 - Engel, Tilman T1 - Assessing the validity of inertial measurement units for shoulder kinematics using a commercial sensor-software system BT - a validation study JF - Health science reports N2 - Background and Aims Wearable inertial sensors may offer additional kinematic parameters of the shoulder compared to traditional instruments such as goniometers when elaborate and time-consuming data processing procedures are undertaken. However, in clinical practice simple-real time motion analysis is required to improve clinical reasoning. Therefore, the aim was to assess the criterion validity between a portable "off-the-shelf" sensor-software system (IMU) and optical motion (Mocap) for measuring kinematic parameters during active shoulder movements. Methods 24 healthy participants (9 female, 15 male, age 29 +/- 4 years, height 177 +/- 11 cm, weight 73 +/- 14 kg) were included. Range of motion (ROM), total range of motion (TROM), peak and mean angular velocity of both systems were assessed during simple (abduction/adduction, horizontal flexion/horizontal extension, vertical flexion/extension, and external/internal rotation) and complex shoulder movements. Criterion validity was determined using intraclass-correlation coefficients (ICC), root mean square error (RMSE) and Bland and Altmann analysis (bias; upper and lower limits of agreement). Results ROM and TROM analysis revealed inconsistent validity during simple (ICC: 0.040-0.733, RMSE: 9.7 degrees-20.3 degrees, bias: 1.2 degrees-50.7 degrees) and insufficient agreement during complex shoulder movements (ICC: 0.104-0.453, RMSE: 10.1 degrees-23.3 degrees, bias: 1.0 degrees-55.9 degrees). Peak angular velocity (ICC: 0.202-0.865, RMSE: 14.6 degrees/s-26.7 degrees/s, bias: 10.2 degrees/s-29.9 degrees/s) and mean angular velocity (ICC: 0.019-0.786, RMSE:6.1 degrees/s-34.2 degrees/s, bias: 1.6 degrees/s-27.8 degrees/s) were inconsistent. Conclusions The "off-the-shelf" sensor-software system showed overall insufficient agreement with the gold standard. Further development of commercial IMU-software-solutions may increase measurement accuracy and permit their integration into everyday clinical practice.

Methods Patients after acute cardiac event with negative subjective expectations about return to work or unemployment (n = 354) were included and randomized in clusters of 3-6 study participants. Clusters were randomized for social counseling and therapy led by a social worker, six sessions of 60 min each in 3 weeks, or control group (usual care: individual counseling meeting by request). The return to work (RTW) status and change in quality of life (QoL, short form 12: Physical and Mental Component Summary PCS and MCS) 12 months after discharge from inpatient CR were outcome measures. Results The regression model for RTW showed no impact of the intervention (OR 1.1, 95% CI 0.6-2.1, P = 0.79; n = 263). Predictors were unemployment prior to CR as well as higher anxiety values at discharge from CR. Likewise, QoL was not improved by social therapy (linear mixed model: Delta PCS 0.3, 95% CI - 1.9 to 2.5; P = 0.77; n = 177; Delta MCS 0.7, 95% CI - 1.9 to 3.3; P = 0.58; n = 215). Conclusions In comparison to usual care, an intensive program of social support for patients during inpatient cardiac rehabilitation after an acute cardiac event had no additional impact on either the rate of resuming work or quality of life.

T1 - Bullying and alexithymia BT - Are there differences between traditional, cyber, combined bullies, and nonbullies in reading their own emotions? JF - Criminal Behaviour and Mental Health N2 - AimsTo investigate whether there are differences among 12-18year-olds in capacity for identifying and/or describing own emotions between traditional bullies, cyber bullies, combined bullies, and nonbullies. MethodsData from self-report questionnaires completed by 897 female and 652 male 12-18year-olds (mean 14.5years, standard deviation 1.68) from Germany and Thailand were analysed using analysis of covariance. ResultsYoung people who reported never having bullied others scored lower on the alexithymia scale than traditional, cyber, or combined bullies. There were no differences between traditional and cyber bullies on this measure, but those who operated in both ways had significantly higher alexithymia scores compared with those who bullied in just one modality.
