A Practice Analysis Survey: Defining The Clinical Practice Of Primary Care Physical Therapy, Edsen Bermudez Donato

Loma Linda University Electronic Theses, Dissertations & Projects

Background and Purpose. Due to changes in the health care delivery systems, physical therapy services have moved toward a primary care model of practice. The purpose of this study was to identify the professional responsibilities, procedures, and knowledge areas of physical therapists practicing in primary care settings.

Subjects. A sample of 212 physical therapists practicing in primary care settings, and a control group of 250 physical therapists not practicing in primary care settings were surveyed.

Methods. The survey instrument was developed with the assistance of a National Advisory Committee (NAC) consisting of 12 subject matter experts. A modified Delphi …

The Effects Of Education On Fear-Avoidance Behavior Of Subjects With Work-Related Low Back Pain, Marie A. Anger

Loma Linda University Electronic Theses, Dissertations & Projects

Background and Purpose. Fear-avoidance behavior contributes to chronic low back pain. The purpose of this study was to determine whether patient education on fear-avoidance behavior added to conventional physical therapy would have significant effects on return to work status in contrast to a comparison group with only physical therapy intervention. Return to work status was measured by the length of time from the initial injury to the subject’s return to work on regular duty.

Subjects. Thirty-four workers’ compensation subjects with low back pain who exhibited fear-avoidance behavior, according to their responses to the Fear- Avoidance Beliefs Questionnaire, were alternately assigned …

Disability Self-Assessment And Upper Quarter Muscle Balance In Females, Eric Glenn Johnson

Loma Linda University Electronic Theses, Dissertations & Projects

Background and Purpose. This study compared upper quarter muscle balance of working female dental hygienists and non-dental hygiene females who had no history of upper quarter pathology. The upper quarter was operationally defined as the shoulder and neck region; and muscle balance, as muscular flexibility and muscular performance. Muscular performance was operationally defined as a combination of strength and endurance.

Subjects. The study group consisted of 41 working dental hygienists between the ages of 22 and 60 years with a mean age of 38 years. The control group consisted of 46 non-dental hygienists between the ages of 20 and 54 …

Factors In Predicting The Number Of Home Care Physical Visits, Bruce D. Bradley

Loma Linda University Electronic Theses, Dissertations & Projects

There has been a significant increase in the utilization of home health care during the past decade. Medicare has attempted to control home care costs by 1) allowing Medicare beneficiaries to join Health Maintenance Organizations, and 2) requiring the use of the Outcome and Assessment Information Set (OASIS) for all patients admitted to home care services. These changes have challenged the home care physical therapist to be a better predictor of the total number of visits needed to complete the rehabilitation process. This was a retrospective study of 335 patients who received home health care physical therapy. The first part …

Toward The Optimal Waveform For Electrical Stimulation, Scott Douglas Bennie

Loma Linda University Electronic Theses, Dissertations & Projects

Electrical stimulation (ES) is used to strengthen muscle, improve abnormal tone, and improve the healing rate of pressure sores. Four male and three female research subjects received four minute bouts of electrically stimulated isometric contractions equal to 10% of the maximal voluntary contraction (MVC) of their right quadriceps muscle to study subjective comfort and physiological responses to different waveforms, including Russian, interferential, sine, and square. Frequency remained constant at 30pps. The pulse width for the Russian waveform was 200ps, while the sine, square, and interferential waveforms used a lOOps pulse width. The amplitude of stimulation was adjusted to maintain the …
