Rehabilitation Treatment Following Total Shoulder Arthroplasty, Debbie Aarhus

Physical Therapy Scholarly Projects

The shoulder is a very complex joint in the human body and, therefore, is easily injured and/or damaged. When conservative methods (pain reducing modalities, exercise, or medication) to treat the injury fail, an alternative method of treatment could be a total shoulder arthroplasty. Corrective surgery alone, however, is not enough. A rehabilitation program involving range of motion and strengthening exercises is fundamental in the successful return of function at the shoulder.

The purpose of this literature review is to provide an overview of shoulder anatomy, surgical procedures of total shoulder arthroplasty, rehabilitation protocols, and outcomes. The information gained from this …

Subtalar Joint Biomechanics, Tom L. Baumgartner

Physical Therapy Scholarly Projects

Subtalar joint movement is transmitted proximally to the lower extremity and distally to the forefoot during gait. Thus, the entire lower kinetic chain is influenced by abnormal subtalar joint biomechanics. If the subtalar joint is forced to compensate for structural deformities of the foot and leg, various lower extremity injuries are likely to develop. The purpose of this study is to examine the normal and abnormal biomechanics of the subtalar joint. In the process, the clinician will be able to identify various subtalar joint abnormalities and relate these to their respective lower kinetic chain pathologies. By correctly assessing the cause …

Vestibular Disorders And Rehabilitation, Stephanie Ann Jones

Physical Therapy Scholarly Projects

The management of patients with vestibular disorders is a formidable problem. Many individuals present to their physician with symptoms of loss of balance and dizziness. A major contributor to sustaining proper upright balance, the vestibular system, consists of a complex network of fluid-filled canals and organs which aid in orientation of the head to vertical and provide information on head movements. The vestibular system is also involved in the sensation and perception of motion and position. Peripheral vestibular dysfunctions, which involve the vestibular organs and/or nerve, can produce a variety of signs and symptoms.

A Review Of Bell's Palsy, Jodi Spicer

Physical Therapy Scholarly Projects

Bell's Palsy is an acute unilateral weakness or paralysis of the facial muscles resulting from peripheral facial nerve dysfunction. Bell's Palsy is the most common cause of unilateral facial weakness. Since idiopathic facial paralysis was first diagnosed, several treatment options have been tried in an effort to influence early and full recovery. The role of physical therapy in the treatment of Bell's Palsy is to exercise the muscle in an attempt to keep the denervated muscle healthy while the injured axons regenerate and reinnervate the muscle. The natural course of Bell's Palsy is a spontaneous return of function in 71 …
