Measurement of scapular dyskinesis using wireless inertial and magnetic sensors: Importance of scapula calibration.

Measurement of 3D scapular kinematics is meaningful in patients with shoulder pathologies showing scapular dyskinesis. This study evaluates the effect of single and double anatomical calibration (0° and 120°) with a scapula locator compared to standard calibration (using sensor alignment with the spina scapulae and static upright posture, ISEO-protocol) on 3D scapular kinematics measured with an inertial and magnetic measurement system (IMMS). Ten patients with scapular dyskinesis performed humeral anteflexion and abduction movements while 3D scapular kinematics were measured using IMMS sensors.

Measurement properties of the Dutch version of the Western Ontario Shoulder Instability Index (WOSI).

Background: The Western Ontario Shoulder Instability Index (WOSI) is a disease-specific shoulder questionnaire to measure quality of life in patients with shoulder instability. The aim of the present study was to translate the WOSI into Dutch and assess its principal measurement properties.

Methods: The WOSI was translated into Dutch according to guidelines in the literature.

Reproducibility of the Dutch version of the Western Ontario rotator cuff Index.

Background: The Western Ontario Rotator Cuff Index (WORC) is a disease-specific shoulder questionnaire, originally developed at the University of Western Ontario, to measure quality of life in patients with rotator cuff disease (RCD). The aim of the present study was to cross-culturally adapt the WORC for use in the Netherlands and to evaluate the reproducibility in patients with RCD.

Materials And Methods: The WORC was translated into Dutch according to leading guidelines in the literature, and 52 patients with RCD completed the questionnaire twice within 2 weeks.
