Patients will frequently see their family physician with an “occasional trigger finger,” or a finger or thumb that gets intermittently stuck in a flexed position. By attempting to extend the digit, it will often suddenly pop out to length. In some cases, the trigger finger is painful. Trigger finger usually occurs in the third or fourth digits, but it can occur in the thumb. Excessive gripping,...

PURPOSE Open release of the A1 pulley is a widely known procedure for the treatment of trigger finger. A subset of patients presents with both trigger finger and a positional contracture of the proximal interphalangeal (PIP) joint. These patients usually have a long history of trigger finger or have already undergone a surgical release of the annular pulley. This study is a retrospective review...

IMPORTANCE Recognition of sagging eye syndrome (SES) as the cause of chronic or acute acquired diplopia may avert neurologic evaluation and imaging in most cases. OBJECTIVES To determine whether SES results from inferior shift of lateral rectus (LR) extraocular muscle (EOM) pulleys and to investigate anatomic correlates of strabismus in SES. DESIGN AND SETTING We used magnetic resonance ima...

The floating wire technique was applied to characterize the focusing properties of the D2 spectrometer magnet to be used in the ANKE installation of the COSY Jülich accelerator facility. Trajectories corresponding to 140–600 MeV/c ejectiles emerging from a target in front of the rectangular-type D2 magnet were measured in order to determine the location of foci where detectors for the physics e...

ion of Implicit Domain Concepts The fact that EUREKA indexes the enhanced problem representation means that its expert-level schemas are not limited to the problem’s initial descriptors. Instead, physics concepts and other inferences about object relations and features are eligible to become norms and indices. This is important for abstracting useful domain-specific concepts that are defined as...

Wire rope and pulley devices are used in various machines. To use these machines more safely, it is necessary to analyze the behavior of the contact between them. In this study, we represent a wire rope by a numerical model of a flexible body. This flexible body is expressed in the absolute nodal coordinate formulation (ANCF), and the model includes the normal contact force and the frictional f...

A simple method for studying operant wheel running in rats. The present report describes an operant running device for rats. The apparatus makes use of an activity wheel driven by a small electric motor. The motor is started by a bar press; once activated, the wheel turns for 3-30 sec. depending on the setting of a timing device. The system is well suited to long term studies of activity patter...

PURPOSE The main purpose of this study was to compare the effect of a specific resistance training program (throwing movement with a pulley device) with the effect of regular training (throwing with regular balls) on overarm throwing velocity under various conditions. METHODS The training forms were matched for total training load, ie, impulse generated on the ball or pulley device. Both trai...
