Introduction: The purpose of this study was to investigate the effects of Kinesio® tape on scapulothoracic joint kinematics during humerothoracic elevation and lowering in asymptomatic participants.

Method: Sixteen males and 24 females participated in data collection using the Polhemus G4 3D electromagnetic motion capture system. Dominant shoulder kinematics were collected while the participant performed three repetitions of elevation in the frontal, sagittal, and scapular planes.

Purpose/background: Objective, reliable, and valid functional tests may assist with the decision-making process for rehabilitation as well as assist in pre-participation screening for targeted interventions to prevent noncontact lower extremity injuries. The purpose of this study was to determine normative values in high school and college basketball and soccer players for four hop tests: the single hop for distance, the triple hop for distance, the crossover hop for distance, and the 6-m timed hop.

Methods: A sample of convenience of 372 (185 females, 187 males) healthy high school and collegiate student-athletes were included in the study (mean age 17.

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 Monitor™ (Innsport, Chicago, IL, USA).

Purpose: Older adults with Alzheimer disease (AD) fall more than twice as often as those without dementia, yet few studies have assessed fall risk in this population. The purpose of the study was to determine whether a fall assessment, the Physical Performance Test 7-item (PPT 7-item), could accurately identify subjects with history of falls in a group of community-dwelling elders with mild AD. An additional purpose was to determine whether the PPT 7-item, a cognitive screen, and/or nonperformance data could predict falling in this population.

Purpose: To investigate the relationship between obesity and gross motor development in children who are developing typically and determine whether body mass index (BMI) predicts difficulty in gross motor skills.

Methods: BMIs were calculated and gross motor skills examined in 50 children who were healthy aged 3 to 5 years using the Peabody Developmental Motor Scales, 2nd edition (PDMS-2). Pearson chi-square statistic and stepwise linear hierarchical regression were used for analysis.

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.

Hand movement recovery and cortical reorganization were studied in 10 subjects with chronic stroke using functional MRI (fMRI) before and after training with an intensive finger movement tracking programme. Subjects were assigned randomly to a treatment or control group. The treatment group received 18-20 sessions of finger tracking training using target waveforms under variable conditions.
