[Purpose] This study aimed to investigate the characteristics of upper quadrant posture of young women with temporomandibular disorders. [Subjects] The participants were 19 female patients with temporomandibular disorders (patient group: mean age, 30.1 years) and 14 controls (control group: mean age, 24.6 years). [Methods] Outcome measures were the neck inclination angle (formed by a line conne...

Forward head and rounded shoulder posture (FHRSP) is theorized to contribute to alterations in scapular kinematics and muscle activity leading to the development of shoulder pain. However, reported differences in scapular kinematics and muscle activity in those with forward head and rounded shoulder posture are confounded by the presence of shoulder pain. Therefore, the purpose of this study wa...

For effective rehabilitation of the shoulder, physical therapists must have correct knowledge of shoulder motion. Reports conflict on whether medial or lateral rotation of the humerus accompanies shoulder flexion. The purpose of this study was to determine the relationship between flexion and rotation at the glenohumeral joint. We determined rotation that accompanied active shoulder flexion by ...

Displaced fracture of the acromion without associated shoulder injury occurs rarely. A 31-year-old gentleman presented with an isolated acromion fracture resulting from a direct trauma to the top of his left shoulder. Open reduction and internal fixation using multiple pins was performed and the fracture was closed without complications. The patient achieved excellent shoulder function and rank...

The main objective was to quantify the effects of five different slopes on trunk and shoulder kinematics as well as shoulder kinetic and muscular demands during manual wheelchair (MWC) propulsion on a motorized treadmill. Eighteen participants with spinal cord injury propelled their MWC at a self-selected constant speed on a motorized treadmill set at different slopes (0°, 2.7°, 3.6°, 4.8°, and...

BACKGROUND Shoulder girdle muscles are important for stabilizing the scapula and orienting the glenoid for upper-extremity motion. However, data describing shoulder girdle strength and how it varies with position is lacking. METHODS A series of experiments was conducted to measure isometric strength at three positions each for elevation, depression, protraction, and retraction of the shoulder...

OBJECTIVE To determine if a low-cost, automated motion analysis system using Microsoft Kinect could accurately measure shoulder motion and detect motion impairments in women following breast cancer surgery. DESIGN Descriptive study of motion measured via 2 methods. SETTING Academic cancer center oncology clinic. PARTICIPANTS 20 women (mean age = 60 yrs) were assessed for active and passiv...
