The purpose of this study was (a) to compare the Jamar Dynamometer, which is widely used to test hand strength, with the Vigonmeter, a commercially avatlable but less well known instrument and (b) to establish norms for use of the Vigorimeter. A total of486 adults ranging in age from 16 to 79 were tested for nght-and left-hand strength using both devices. Correlations between the two instruments were moderately strong, suggesting reasonable comparability. Correlations for strength and age, although statistically significant, were so low as to be oflittle practicaluse. However, cor-M. Iaurita Fike, OTR, is

The purpose of our study was to determine the reliability of the model PC5030PT computerized Jamar dynamometer (J. A. Preston, Jackson, MI). A test-retest reliability study was conducted in which 33 normal subjects were tested three times over a 6-week period. Standard procedures for assessing grip strength were followed. Both left and right hands were tested. We quantified three characteristics of the force curve: (a) the slope of the rise in force, (b) the maximal or peak force, and (c) the mean sustained force over the last 3 sec of a 5-sec contraction. Reliability was good with intraclass reliability coefficients ranging from .84 to .93. We conclude that the computerized Jamar will yield reliable measurement of grip strength if the instrument is calibrated properly and if standardized procedures for grip strength testing are followed.

Occupational therapists are becoming more involved in the treatment of persons with multiple personality disorder. Occupational therapy literature concerning treatment of this group of patients, however, is sparse. Clinical manifestations of multiple personality disorder include common alter personalities with distinct roles and functions, age-related behavioral patterns, and physiological differences. By recognizing and understanding these differences and characteristics and their relationship to treatment goals, occupational therapists can better use their background in life roles and occupations to increase the functional daily living skills of patients with multiple personality disorder.

Arizona occupational and physical therapists were surveyed about their needs for education in arthritis. Responses to statements regarding attitudes, knowledge, willingness to learn, and preferred methods of learning were subjected to chi-square analysis. The results showed that a significant number of both occupational and physical therapists are deficient in knowledge about the disease and maintain negative attitudes about patients with rheumatoid arthritis. Both groups indicated a high interest in continuing education about arthritis. The preferred method of learning was self-study guides.
