Reliability of isokinetic measurements of hip muscle torque in young boys.

The purpose of this study was to determine the reliability of measurements of hip muscle torque obtained with the Cybex II isokinetic dynamometer from healthy young boys. Twenty-nine healthy boys, aged 6 to 10 years, were tested two times at one- to two-week intervals. Torque of the hip flexors and extensors and the hip abductors and adductors was assessed at angular velocities of 30 degrees and 90 degrees/sec. The torque generated by each muscle group at 30 degrees/sec was similar to the torque generated at 90 degrees/sec. Intraclass correlation coefficients (ICCs) were used to determine test-retest reliability for measurements of each of the muscle groups at both angular velocities. The ICCs were higher for hip flexion and extension than they were for hip abduction and adduction. The highest ICC (ICC = .84) was found for hip extension at 90 degrees/sec. The ICCs for hip abduction and adduction at both angular velocities were less than .60. Factors that possibly contributed to the relatively low reliability in hip abduction and adduction are discussed.

Developing problem-solving skills in the classroom.

The purposes of this article are 1) to describe a series of classroom activities emphasizing problem-solving skills that was designed for physical therapy students in their first year of professional course work and 2) to examine the students' initial attitudes toward the learning experiences. Simulated patient information was presented in writing, on videotape, or by role-playing. Students defined the case problem, developed and ranked clinical problems, set goals, and considered treatment possibilities. Completion of a problem-oriented "subjective, objective, assessment, plan" patient-status note, based on the information derived from the problem-solving activities, was part of the learning experience. Changes in course design that were made during a three-year period are identified. A discussion of the difficulties related to student acceptance of and interest in problem-solving activities is included.

Force-time measurements of knee muscle functions of subjects with multiple sclerosis.

The purpose of this study was to determine whether the time-rate of muscle tension development, the muscle tension-maintaining capacity, and the reciprocal inhibition time of muscles in subjects with multiple sclerosis were significantly different from those of healthy subjects. An isokinetic dynamometer was used to evaluate the quadriceps femoris and hamstring muscles of 15 Experimental Group subjects with multiple sclerosis and 17 healthy Control Group subjects. The muscles were tested isometrically at 45 degrees of knee flexion and isokinetically at speeds of 30 degrees/sec and 90 degrees/sec. The subjects with multiple sclerosis demonstrated a significant (p less than .001) slowing of the time-rate of muscle tension development and a significant (p less than .005) decrease in muscle tension-maintaining capacity when compared with healthy subjects. The difference in the reciprocal inhibition time of muscles of the Experimental and Control Groups was not significant. When the reciprocal inhibition time of muscles was expressed as a percentage of the total torque curve, however, a significant prolongation (p less than .001) was observed in the subjects with multiple sclerosis.

Problem-solving approach to clinical education.

A problem-solving method to provide appropriate clinical learning experiences was developed for physical therapy students enrolled in their first year of professional course work. Clinicians from selected facilities were asked to participate in a clinical rotation over a two-quarter period. Using a problem-solving format, each clinician was responsible for a two-hour presentation relating to a disease or disability. Each rotation was repeated weekly for seven different groups of 10 students. During the rotation, the clinician presented a patient with a particular disability or disease and worked with the students to identify patient problems, establish treatment goals, and discuss methods used to achieve the goals. The difficulties encountered with the clinical experiences and the positive aspects of the experiences are discussed.

Clinical Competence

Values of activities of daily living. A survey of stroke patients and their home therapists.

People's values influence their actions and efforts. Based on the assumption that a patient's values can be a guide to successful rehabilitation, the values of 15 activities of daily living as perceived by stroke patients and their home therapists were studied. Twenty-six stroke patients living at home and their 10 visiting occupational and physical therapists participated in the study. The study results indicated that the relative importance of each activity of daily living perceived by the patient group and by the therapist group was similar. Among the 29 therapist-patient pairs, however, only 1 pair showed significantly similar views regarding the values of these activities to the patient. Patients' age, gender, income level, duration since onset of stroke, impaired body side, and independence level in activities were significantly related to their values of certain activities of daily living. The relative value stroke patients living at home place on each activity of daily living could serve as a guide for sequencing learning steps during activities of daily living training in a hospital or rehabilitation setting. Determining patient rehabilitation goals as influenced by personal values may shorten rehabilitation time, be more cost-effective, and aid in the retention of gains made in the rehabilitation setting.

Activities of Daily Living

Implementation of the problem-oriented progress note in a skilled nursing facility.

Problem-oriented style progress notes were implemented in a skilled nursing facility where problem-oriented medical records were not in use. The problem-oriented note consists of subjective information, objective information, analysis or assessment of the problems, and plan for treatment, and is called a SOAP note. Six physical and occupational therapists used the method of note writing for an eight-week trial period. The author audited the records for errors in using the SOAP note throughout the experimental period. Therapists responded to a questionnaire following the study to assess their attitudes on using the SOAP note. Implementation of the problem-oriented progress note was satisfactory, with the exception of defining the problem list. The therapists reacted positively toward using the problem-oriented method of recording patient progress or status and recommended that its use be taught to physical and occupational therapy students.

Evaluation Studies as Topic

Human figure drawings by children with Duchenne's muscular dystrophy.

Seventy-two human figure drawings by forty-three patients who had a diagnosis of Duchenne's muscular dystrophy were examined. The study includes a description of these human figure drawings according to eleven emotional indicators and according to directionality quadrants. When the human figure drawings were used as a projective tool, four personality traits of some of the children were identified: physical inadequacy, immaturity, body anxiety, and insecurity. Both the emotional indicators and the quadrant in which the figures appeared were examined in relation to stages of the disease process to see if the human figure drawings of the children might reflect more stress and anxiety at a particular stage of the disease. Suggestions for improvements and recommendations for future study are given.
