Examine the accuracy of visual estimates of various joint angles by physical therapists at various levels of education and clinical practice, taking into account years of experience, areas of practices and specialty certifications.

Physical therapists oftentimes will estimate rather than measure joint range of motion. The accuracy of visual estimates of various joint measurements has not been previously assessed. No comparison has been done for years of experience and accuracy of estimations. This study will create a survey with pictures of joints at previously measured angles and therapists and students will be asked to estimate the range of motion. Various statistical analyses will be performed to determine accuracy and comparisons.

Inclusion Criteria:

• licensed physical therapists
• students currently enrolled in an accredited doctorate of physical therapy program

Exclusion Criteria:

• students have not been trained in range of motion measurements
• are not licensed physical therapists

adults who are currently enrolled in a DPT program or graduates and licensed physical therapy practioners.
