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. Forward multiple regression
analyses explained the variation accounted for by glenohumeral and
scapulothoracic motions.
RESULTS: The mean internal rotation to accomplish back
washing was 85 (standard deviation 24) degrees glenohumeral internal rotation
contributed. The mean humerothoracic elevation ranged between 46 (standard
deviation 12) degrees for washing the contralateral axilla and 119 (standard
deviation 10) degrees for hair combing. Glenohumeral abduction, scapular anterior
tipping, and scapular upward rotation contributed to completing feeding, hair
combing, reaching overhead, and washing the contralateral axilla. Glenohumeral
flexion contributed to completing feeding, reaching overhead, and washing the
contralateral axilla. Scapular internal rotation contributed to completing
feeding. CONCLUSIONS: Glenohumeral abduction and scapulothoracic upward rotation
were necessary to accomplish feeding, combing hair, reaching overhead, and
washing the contralateral axilla. Glenohumeral internal rotation was necessary to
accomplish back washing. Interventions addressing glenohumeral and
scapulothoracic motions in patients who are having difficulty in completing
activities of daily livings may prove beneficial.
