Study Design: Repeated-measures analysis of intervention. Objectives: To determine the effects of foot orthoses on quality of life for individuals with patellofemoral pain who demonstrate excessive foot pronation. Background: Foot orthoses are a common intervention for patients with patellofemoral pain. Limited information is available, however, regarding the effects of foot orthoses on quality of life for these patients. Methods and Measures: Sixteen subjects with patellofemoral pain who also exhibited signs of excessive foot pronation were studied. Subjects underwent a 2-week period of baseline study followed by custom foot orthotic intervention. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was administered to subjects at the time of screening, just prior to foot orthotic intervention, and at 2 weeks and 3 months following foot orthotic intervention. Results: Wilcoxon matched-pairs signed-rank test results indicated statistically significant improvements in the pain and stiffness subscales 2 weeks following the start of foot orthotic intervention. All WOMAC subscale scores were significantly improved at 3 months compared with preinterven-tion measurements. Conclusions: Custom-fitted foot orthoses may improve patellofemoral pain symptoms for patients who demonstrate excessive foot pronation.
The aim of this study was to determine the impact of inter-professional teaching on the application of ergonomic operator and patient positioning. A randomized case-control study was conducted with 83 first-year dental students at the UNC Chapel Hill Adams School of Dentistry. Forty-nine percent (n=41) of the students solicited participated. All students participated in a didactic lecture on ergonomics, along with a pre-clinical practice session with peer patients. During the clinical practice session students in the case group received ten minutes of one-on-one individualized instruction. Two weeks later, all students were assessed using a rubric on operator and patient positioning, while simulating restorative work. There was a statistically significant difference between the two groups with respect to the composite ergonomic compliance score (p=0.005), operator shoulder abduction position (p=0.03), and lateral flexion of the spinal column (p=0.02). Hands-on individualized instruction positively effects ergonomic compliance. v TABLE OF CONTENTS LIST OF TABLES………………………………….…………………………………………….vi LIST OF FIGURES…………………………………………………………………………..….vii
