Goal-dependent modulation of the long-latency stretch response at the shoulder, elbow, and wrist.
Many studies have demonstrated that muscle activity 50-100 ms after a mechanical perturbation (i.e., the long-latency stretch response) can be modulated in a manner that reflects voluntary motor control. These previous studies typically assessed modulation of the long-latency stretch response from individual muscles rather than how this response is concurrently modulated across multiple muscles...
متن کاملLong-latency responses during reaching account for the mechanical interaction between the shoulder and elbow joints.
Although considerable research indicates that reaching movements rely on knowledge of the arm's mechanical properties and environment to anticipate and counter predictable loads, far less research has examined whether this degree of sophistication is present for on-line corrections during reaching. Here we examine the R2/3 response to mechanical perturbations (45-100 ms, also called the long-la...

متن کاملUsing lesson study to integrate information literacy throughout the curriculum.
To develop evidence-based practice skills, students need to be capable of retrieving various levels of scholarly information, evaluating its usefulness, and applying it to clinical practice. The authors discuss the process of developing an information literacy curriculum for a cohort of students over a 5-semester nursing program using lesson study.
متن کاملLong-Latency Reflexes of the Human Arm Reflect an Internal Model of Limb Dynamics
A key feature of successful motor control is the ability to counter unexpected perturbations. This process is complicated in multijoint systems, like the human arm, by the fact that loads applied at one joint will create motion at other joints [1-3]. Here, we test whether our most rapid corrections, i.e., reflexes, address this complexity through an internal model of the limb's mechanical prope...
