Clinical diagnostic accuracy and magnetic resonance imaging of patients referred by physical therapists, orthopaedic surgeons, and nonorthopaedic providers.

Study Design: Nonexperimental, retrospective design.

Objectives: This study was designed to compare clinical diagnostic accuracy (CDA) between physical therapists (PTs), orthopaedic surgeons (OSs), and nonorthopaedic providers (NOPs) at Keller Army Community Hospital on patients with musculoskeletal injuries (MSI) referred for magnetic resonance imaging (MRI).

Background: US Army PTs are frequently the first credentialed providers privileged to examine and diagnose patients with musculoskeletal injuries.

Improvement in sit-up performance associated with 2 different training regimens.

Study Design: Factorial experimental design.

Objective: To compare the outcomes of 2 different abdominal muscular fitness training regimens on sit-up performance across sex and abdominal muscular fitness level.

Background: Researchers suggest that the curl-up, when compared to the sit-up, optimizes the challenge to the abdominal muscles while minimizing shear and compressive forces on the lumbar spine.
