Long-latency reflexes account for limb biomechanics through several supraspinal pathways
Accurate control of body posture is enforced by a multitude of corrective actions operating over a range of time scales. The earliest correction is the short-latency reflex (SLR) which occurs between 20-45 ms following a sudden displacement of the limb and is generated entirely by spinal circuits. In contrast, voluntary reactions are generated by a highly distributed network but at a significan...
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...
متن کاملEffects of leg pedaling on early latency cutaneous reflexes in upper 2 limb muscles
31 The functional coupling of neural circuits between the upper and lower 32 limbs involving rhythmic movements is of interest to both motor control 33 research and rehabilitation science. This coupling can be detected by 34 examining the effect of remote rhythmic limb movement on the modulation 35 of reflex amplitude in stationary limbs. The present study investigated the 36 extent to which rh...

متن کاملBiomechanics of Upper Limb Orthoses
INTRODUCTION Functional impairment of [parts of] the upper limb has many different expressions. Sound biomechanical analysis is at the basis of the management of the physical challenges involved. An outline of the basics of a mechanical systems approach is presented below. Orthoses are among the many treatment options for upper limb impairments. An orthosis can be defined as a mechanical constr...
