Isokinetic Ratios Of Concentric And Eccentric Work Production Of Internal And External Rotators In A Simulated Throwing Pattern, Deane M. Chinen

Physical Therapy Scholarly Projects

Shoulder internal and external rotators have been the focus of several isokinetic studies. However, an examination of muscular work in a functional pattern has not been investigated. Therefore, the purpose of this study was twofold: 1) to establish normative ratios of concentric to eccentric work of internal and external shoulder rotators respectively, and 2) to provide information on the balance of strength in shoulder rotators during a simulated throwing pattern.

Twenty-seven subjects without shoulder pathology were tested on the KINCOM isokinetic dynamometer. The statistics for the whole group revealed 55% more concentric internal rotation work in relation to eccentric external …

The Effect Of Intraarticular Injection Of Morphine Following Knee Arthroscopy, Chandel Dietz

Physical Therapy Scholarly Projects

Postoperative pam IS common following knee arthroscopy and has been typically controlled with opioids, the most popular of which is morphine. Morphine has been traditionally administered by intramuscular, intravenous, or epidural injections. These methods of administering morphine have been very effective in producing prolonged analgesia; however, they have also produce negative central nervous system side effects.

Recent research has suggested administering morphine via intraarticular injections to provide postoperative analgesia without the central nervous system side effects. However, there is little evidence to suggest that this method is effective. Therefore, the purposes of this randomized, double-blinded study were to 1) investigate …

Concentric And Eccentric Isokinetic Normative Ratio Values Of The Quadriceps Muscle In Asymptomatic Knee Subjects, Donna Ho

Physical Therapy Scholarly Projects

Technological advances in isokinetic devices allow the clinician to objectively assess and rehabilitate injuries using concentric and eccentric contractions at different speeds. The purpose of this research project is to establish concentric and eccentric normative ratio values of the quadriceps muscle on the Kinetic Communicator (Kin-Com, Chattecx Corp., Chattanooga, TN) dynamometer. A sample of 19 females and 12 males aged 20-38 (mean for females = 24.32 ± 3.87, mean for males = 27.67 ± 5.80) were tested on the KinCom for maximum concentric and eccentric torque values during knee extension using a 70° range of motion at 90 and 1200/sec. …

Cardiac Rehabilitation: Patient Recall Of Exercise Guidelines And Implications For Physical Therapists, Mary Jones

Physical Therapy Scholarly Projects

The efficacy of a cardiac rehabilitation program depends on adequate patient compliance. Patients with coronary heart disease and those recovering from heart surgery may have a successful recovery from acute episodes of myocardial infarction or following operation. It must be recognized that they may require long-term supervision and support. The purpose of this study was to identify if diagnosis of myocardial infarction or heart surgery was a determinant of compliance with exercise guidelines once a patient has graduated from a level II cardiac rehabilitation program. A retrospective chart audit was performed for the years 1991-1994. A data sheet was used …

A Wrist And Cervical Screening Of Grand Forks City Employees: A Pilot Study, William D. Jr. Kukuk

Physical Therapy Scholarly Projects

Cumulative Trauma Disorders (CTDs) developed at work are caused by repetitive movements or sustained postures. Carpal Tunnel Syndrome (CTS) and Cervical Radiculopathy (CR) are both CTDs resulting from repetitive wrist movements and sustained cervical postures respectively. Although both conditions can present with similar symptoms in the exact same hand and finger location, there has been no research comparing the prevalence of CTS and CR symptoms in a given population.

The purpose of this study was to identify hand and finger symptoms and correlate the severity of the symptoms with objective measures. Thirty employees of the City of Grand Forks, ND, …

The Lateral Scapular Slide Test: Is It Valid In Detecting Glenohumeral Impingement Syndrome?, Denise G. Litchfield

Physical Therapy Scholarly Projects

Recent literature has focused on instability of the scapulothoracic joint and on resulting scapular positions. Weakness of the scapular musculature can allow the scapula to slide laterally, leading to abnormal glenohumeral biomechanics and to subsequent shoulder pathology. Kibler1 has described the lateral scapular slide test (LSST) as a method of measuring lateral translation of the scapula. A significant difference between right and left scapular positions, as indicated by a discrepancy of greater than one centimeter side-to-side, may indicate functional scapulothoracic instability. The purpose of this study was to evaluate validity of the LSST, measured in two positions. Modified LSST measurements …

The Relationship Between Vertical Jump Scores And Peak Force Measurements Of An Isokinetic Leg Press, David M. Silkey

Physical Therapy Scholarly Projects

This study evaluated potential correlations between related closed kinematic chain strength measurements on a Kin-Com isokinetic machine and a functional strength test. The correlation between standing vertical jump height and isokinetic leg press measurements were statistically analyzed. The following measurements were obtained from 22 subjects (mean age of 24.4 years): a body weight measurement, a vertical jump score, and the force measurements of an isokinetic leg press at 90°/second on each leg. Pearson correlation coefficients were significant (p < .001) when power quotient scores (vertical jump height multiplied by body weight) were compared to leg press results. However, second-order partial correlation coefficients did not find a significance (p > .005) between vertical jump scores and isokinetic leg press results when weight and gender were considered. A significant difference (p < .001) existed between left leg press and right leg press measures. Although isokinetics are useful for lower extremity assessment, this study found that the isokinetic leg press may not be appropriate in determining functional ability.

A Comparison Study Of Cervical Range Of Motion Between Unilateral Breathers And Bilateral Breathers In Collegiate Swimmers During Freestyle Swimming, Nadine K.M. Takai

Physical Therapy Scholarly Projects

The purpose of this study was to determine if there is a difference in cervical rotation between unilateral breathers and bilateral breathers for freestyle swimmers. The sample consisted of 44 (23 males, 21 females) University of North Dakota Varsity swim team members. Among the swimmers there were 19 bilateral breathers, 21 right unilateral, and 4 left unilateral breathers. The CROM device was the tool used to measure cervical rotation. An ANOVA analysis showed no significant difference in right rotation (p=.6585) and total rotation (p=.0693) for any breathing style, however a significant difference existed for left rotation (p=.0078) between bilateral and …

The Effects Of Velocity On Force Production Of The Elbow Flexors During Eccentric Isokinetic Muscle Contraction, Tracie Hildre

Physical Therapy Scholarly Projects

The traditional eccentric force-velocity curve illustrates a continuous increase in muscle force production as velocity increases. Recently, this curve has been scrutinized by some researchers who have found a plateau or decline in eccentric force production at the higher velocities. The purpose of this study was to examine the eccentric isokinetic force-velocity curve of the elbow flexor muscles over a broad range of velocities to observe whether it follows the traditional force-velocity curve.

Fourteen healthy female and six healthy male volunteers were tested using. the Kinetic Communicator Dynamometer at velocities of 30, 60, 90, 120, 150, 180, and 210 degrees …

Patellofemoral Joint Mechanics And Their Clinical Relevance, William S. Hokanson

Physical Therapy Scholarly Projects

Patellofemoral joint dysfunction is a common ailment affecting one in four of the general population and 30% of the athletic population. Patellofemoral dysfunction may stem from a number of different clinical diagnoses. The most common of these is chondromalacia patella. The term chondromalacia patella, however, refers only to a softening or fissuring of the retropatellar surface of the patella and cannot be used to diagnose all patellofemoral pain. Clinical diagnosis is sometimes very difficult because these patients present with a number of vague and nonspecific signs and symptoms.

The purpose of this literature review is to offer a clear, concise …
