Proprioceptive Qualities in Manual Control

Human force proprioception has previously been shown to be important in manual control tasks. Recent experiments suggest that force proprioception is more accurate than position proprioception. Still, knowledge about proprioceptive qualities and their relevance in manual control is lacking or inconsistent. This research aims to experimentally...

Identifying intrinsic and reflexive contributions to low-back stabilization

Motor control deficits have been suggested as potential cause and/or effect of a-specific chronic low-back pain and its recurrent behavior. Therefore, the goal of this study is to identify motor control in low-back stabilization by simultaneously quantifying the intrinsic and reflexive contributions. Upper body sway was evoked using continuous...

Identifying intrinsic and reflexive properties of the low-back by inertial loading

Abnormal neuromuscular control (NMC) has been suggested as a cause or effect of a-specific low back pain. This study aimed to gain more insight into the stabilization of the low back during postural control by developing a method to study the intrinsic and reflexive components of NMC. Inertial loading of the trunk by perturbation of subjects on...

A rigorous model of reflex function indicates that position and force feedback are flexibly tuned to position and force tasks

This study aims to quantify the separate contributions of muscle force feedback, muscle spindle activity and co-contraction to the performance of voluntary tasks (‘‘reduce the influence of perturbations on maintained force or position’’). Most human motion control studies either isolate only one contributor, or assume that relevant reflexive...
