Comparison of three methods used to obtain a neutral plaster foot impression.

The purpose of our study was to compare the forefoot-to-hindfoot angles obtained from three methods used to obtain a neutral plaster impression of the foot. The three methods were 1) supine nonweight-bearing (S), 2) prone nonweight-bearing (P), and 3) sitting semiweight-bearing (SW). We obtained foot casts from both feet of 11 female subjects for each of the three methods and used a manual goniometer to measure the forefoot-to-hindfoot angle for each pair of casts. The F ratios were significant for the variables left-right foot (p less than .0001) and impression method (p less than .001) using a within-subject two-factor analysis of variance. The impression methods S and P were found to be significantly different from SW, but not significantly different from each other, using a Tukey's post hoc comparison. The results indicate that the same forefoot-to-hindfoot alignment can be obtained using either the S or P method but not with the SW method.

Clinical orthopedic medicine course for physical therapy students. Aligning content with current practice.

The purpose of our study was to obtain information that would help align instruction in a clinical orthopedic medicine course for physical therapy students with the current practice of physical therapists. We sent a questionnaire concerning treatment of orthopedic conditions to 3,000 physical therapists. Of the 1,804 (60%) respondents, 58.8% were in general practice, and 35% combined specialty areas with general practice. The respondents indicated that they treated two distinct groups (four categories each) of musculoskeletal disorders. Of the respondents, 87.6% spent less than five hours a week treating bone infections, tumors, and developmental and congenital disorders, whereas 63.4% worked more than five hours a week with fractures and dislocations, low back and neck pain, ligament and soft tissue injuries, and arthritis. We provide a model that uses survey results and course content analysis for planning critical orthopedic medicine instruction for physical therapy students.

Selection of physical therapy students: interview methods and academic predictors.

The purpose of this study was to determine which preprofessional academic and personal characteristics were related to academic and clinical success in a physical therapy program. Individual interviews used for the class of 1982 (N = 25) and group interviews for the class of 1983 (N = 31) were studied to determine which interview type was the stronger predictor of later performance. Correlations of grade point averages (GPAs) and interview scores with academic and clinical grades were calculated. Stepwise regressions were performed to identify the stronger relationships. Preprofessional science and cumulative GPAs for the class of 1982 were moderately, but significantly correlated with cumulative GPAs in the program (r = .54, p less than .05, and r = .50, p less than .05, respectively). Only science GPA for the class of 1982 was retained in the stepwise regression (R2 = .31, p less than .006). All other correlations were low, and correlations for the class of 1983 were lower than for the class of 1982. Neither the academic nor personal characteristics studied were strong predictors of performance in the professional physical therapy educational program.
