Purpose: To evaluate shoulder complex kinematics in persons with chronic upper extremity (UE) impairments due to stroke and determine if kinematics predicts motor function based on the Fugl-Meyer Motor Assessment (FMA).

Methods: Sixteen stroke survivors with chronic UE impairments (age range = 46-80 years, male = 8, female = 8, mean (SD) 66 (40) months post-stroke) performed the UE portion of the FMA with the shoulder/elbow subscale (FM_se) documented. Three-dimensional kinematics of the shoulder complex was collected with the Motion Monitorâ„¢ (Innsport, Chicago, IL, USA).

Objective: To describe the contributions of glenohumeral and scapulothoracic joints in performing combing hair, feeding, reaching overhead, washing the back, and washing the contralateral axilla.

Design: A three-dimensional electromagnetic motion capture system was used to collect humerus, scapula, and trunk kinematic data during activities of daily living completion. Descriptive statistics were calculated for the primary humerothoracic motion.

Background: A sagittal plane spine reposition sense device (SRSD) has been developed. Two questions were addressed with this study concerning the new SRSD: 1) whether spine movement was occurring with the methodology, and 2) where movement was taking place.

Methods: Sixty-five subjects performed seven trials of repositioning to a two-thirds full flexion position in sitting with X and Y displacement measurements taken at the T4 and L3 levels.

Study Design: Prospective cohort study.

Objective: To determine the effect of idiopathic loss of shoulder range of motion on scapular kinematics.

Background: Subjects with idiopathic loss of shoulder range of motion have difficulty performing activities of daily living.

Background And Purpose: People with idiopathic loss of shoulder range of motion (ROM) have difficulty completing activities of daily living. This investigation was performed to determine the association between active glenohumeral ROM and function and to develop a multiple regression equation to explain variation in function in people with idiopathic loss of shoulder motion.

Subjects And Methods: This was a comparative study of 21 subjects (18 female, 3 male), using measurements of shoulder kinematics and administration of the Shoulder Rating Questionnaire (SRQ).

Background: Subjects with idiopathic loss of shoulder motion have difficulty sleeping, performing overhead activities, and completing activities of daily living. Treatment has been variable in approach and success. Cyriax's proposed shoulder capsular pattern was external rotation most limited followed by abduction followed by internal rotation.

Background: Serratus anterior strengthening is used in prevention and treatment programs for poor scapular control. In certain clinical cases, exercises substantially activating the serratus with minimal upper trapezius activation are preferred.

Hypothesis: The standard push-up plus would show both the highest serratus anterior activation and lowest upper trapezius/ serratus ratios for both groups and all phases.

Objectives: To describe 3-dimensional humeral motion in subjects with frozen shoulder and to determine whether a consistent capsular pattern of restriction was present.

Design: Descriptive study including repeated measurements of shoulder kinematics.

Setting: Motion-analysis laboratory.
