Robotic exoskeletons: a perspective for the rehabilitation of arm coordination in stroke patients
Upper-limb impairment after stroke is caused by weakness, loss of individual joint control,
spasticity, and abnormal synergies. Upper-limb movement frequently involves abnormal …

Feasibility of muscle synergy outcomes in clinics, robotics, and sports: a systematic review
In the last years, several studies have been focused on understanding how the central
nervous system controls muscles to perform a specific motor task. Although it still remains an …

Common muscle synergies for balance and walking
SA Chvatal, LH Ting - Frontiers in computational neuroscience, 2013 - frontiersin.org
Little is known about the integration of neural mechanisms for balance and locomotion.
Muscle synergies have been studied independently in standing balance and walking, but …

Involuntary paretic wrist/finger flexion forces and EMG increase with shoulder abduction load in individuals with chronic stroke
LC Miller, JPA Dewald - Clinical neurophysiology, 2012 - Elsevier
OBJECTIVE: Clinical observations of the flexion synergy in individuals with chronic
hemiparetic stroke describe coupling of shoulder, elbow, wrist, and finger joints. Yet …

Long-latency reflexes account for limb biomechanics through several supraspinal pathways
IL Kurtzer - Frontiers in integrative neuroscience, 2015 - frontiersin.org
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 …

Planning of ballistic movement following stroke: insights from the startle reflex
CF Honeycutt, EJ Perreault - 2012 - journals.plos.org
Following stroke, reaching movements are slow, segmented, and variable. It is unclear if
these deficits result from a poorly constructed movement plan or an inability to voluntarily …

Effects of early and intensive neuro-rehabilitative treatment on muscle synergies in acute post-stroke patients: a pilot study
Background After a stroke, patients show significant modifications of neural control of
movement, such as abnormal muscle co-activation, and reduced selectivity and modulation …
