A Fine-Wire Electromyographic Investigation of the Gluteus Minimus and Gluteus Medius Muscles

Abstract

The purpose of this study was to investigate the functions of the gluteus minimus and gluteus medius muscles through the use of fine-wire electromyography. Electrical activity of the gluteus minimus and gluteus medius muscles of 13 subjects, six females and seven males, was recorded during a series of basic anatomical movements. Results showed that the gluteus minimus functioned as an abductor, medical rotator, extensor, and in some cases a flexor of the thigh. The gluteus medius functioned as an abductor, extensor, and medical rotator in six of the 13 subjects. It also exhibited some activity during flexion in five of the subjects tested.     

The effects of consultee-centered consultation on teacher behavior

The purpose of this investigation was to respond to two deficiencies in past consultation research. It described the consultee-centered consultation techniques which were used, and it attempted to demonstrate the effectiveness of consultee-centered consultation in changing observable teacher behavior. Evidence was presented to show how consultation was followed by a reduction in the negative verbal behavior of two out of three teachers who participated in the study. An attempt was made to show how this study related to Caplan's (1970) assumptions regarding consultee-centered case-consultation. It was concluded that multiple baseline designs offer a viable approach to experimental research in consultation with small numbers of subjects.
