DYSKIMOT: An UltraLowCost Inertial Sensor to Assess Headxe2x80x99s Rotational Kinematics in Adults during the DidrenLaser Test Various noninvasive measurement devices can be used to assess cervical motion. The size, complexity, and cost of goldstandard systems make them not suited to clinical practice, and actually difficult to use outside a dedicated laboratory. Nowadays, ultralowcost inertial measurement units are available, but without any packaging or a userfriendly interface. The socalled DYSKIMOT is a homedesigned, smallsized, motion sensor based on the latter technology, aiming at being used by clinicians in xe2x80x9creallife situationsxe2x80x9d. DYSKIMOT was compared with a goldstandard optoelectronic system (Elite). Our goal was to evaluate the DYSKIMOT accuracy in assessing fast head rotations kinematics. Kinematics was simultaneously recorded by systems during the execution of the DidRen Laser test and performed by 15 participants and nine patients. Kinematic variables were computed from the position, speed and acceleration time series. Twoway ANOVA, Passingxe2x80x93Bablok regressions, and dynamic time warping analysis showed good to excellent agreement between Elite and DYSKIMOT, both at the qualitative level of the time series shape and at the quantitative level of peculiar kinematical eventsxe2x80x99 measured values. In conclusion, DYSKIMOT sensor is as relevant as a goldstandard system to assess kinematical features during fast head rotations in participants and patients, demonstrating its usefulness in both clinical practice and research environments.

Assessment of Scapulothoracic, Glenohumeral, and Elbow Motion in Adhesive Capsulitis by Means of Inertial Sensor Technology: A WithinSession, IntraOperator and InterOperator Reliability and Agreement Study Adhesive capsulitis (AC) is a glenohumeral (GH) joint condition, characterized by decreased GH joint range of motion (ROM) and compensatory ROM in the elbow and scapulothoracic (ST) joint. To evaluate AC progression in clinical settings, objective movement analysis by available systems would be valuable. This study aimed to assess withinsession and intra and interoperator reliabilityagreement of such a motion capture system. The MVNAwindaxc2xae system from Xsens Technologies (Enschede, The Netherlands) was used to assess ST, GH, and elbow ROM during four tasks (GH external rotation, combing hair, grasping a seatbelt, placing a cup on a shelf) in 10 AC patients (mean age  54 (xc2xb1 6), 7 females), on two test occasions (accompanied by different operators on second occasion). Standard error of measurements (SEMs) were below 1.5xc2xb0 for ST proretraction and 4.6xc2xb0 for GH inexternal rotation during GH external rotation; below 6.6xc2xb0 for ST tilt, 6.4xc2xb0 for GH flexionextension, 7.1xc2xb0 for elbow flexionextension during combing hair; below 4.4xc2xb0 for GH abadduction, 13xc2xb0 for GH inexternal rotation, 6.8xc2xb0 for elbow flexionextension during grasping the seatbelt; below 11xc2xb0 for all ST and GH joint rotations during placing a cup on a shelf. Therefore, to evaluate AC progression, inertial sensors systems can be applied during the execution of functional tasks.
