Physical Therapy Scholarly Projects

Purpose/Hypothesis: Rotation of the spine is a common movement used to complete daily activities and participate in sports. As a contributing factor to back injuries, the performance of spinal rotation is an important consideration for the rehabilitation of current and prevention of future back injuries. Muscles involved in spinal rotation have been researched, though limited findings exist for one of the largest back muscles, the Latissimus Dorsi (LD). The LD muscle contributes to many movements of the trunk and limbs given its multiple attachment sites including the pelvis, ribs, scapula, and humerus. Influence of the LD on spinal rotation has …

Physical Therapy Scholarly Projects

Background and Purpose. The purpose of the study was to record and analyze muscle recruitment patterns of the gluteus medius and gluteus maximus muscles when performing a side lying abduction exercise requiring consistent force to roll a ball up and down the wall using the dominant lower extremity. Comparisons were made between the use of either a small, medium or large ball. The subjects performed a standing abduction exercises with theraband around both ankles as well.

Case Description. Fifteen subjects were recruited from the University of North Dakota Department of Physical Therapy to perform the four different types of exercises. …
