Spatiotemporal coordination in children with unilateral cerebral palsy: Insights from a bimanual goal-directed task.
Eur J Paediatr Neurol

Background: In children with unilateral cerebral palsy (uCP), bimanual assessments mostly focus on qualitative assessments of the impaired upper limb during bimanual tasks, which do not capture the spatiotemporal coordination between both hands. Hence, we aimed to advance our understandings in spatiotemporal coordination in children with uCP compared to typically developing children (TDC) using a bimanual, asymmetrical, goal-directed task.
Participants And Methodology: In this observational study, thirty-seven children with uCP (11y8m±2y10m, 20 males, 16 right-sided uCP, Manual Ability Classification System level I = 23, II = 11, III = 3) and 37 age and sex-matched TDC opened a box with one hand and pressed a button inside using the opposite hand.
Impact of Visual Feedback Configurations in a Task-Oriented Immersive Virtual Reality Mirror Therapy.
IEEE Trans Neural Syst Rehabil Eng
November 2024
Article Synopsis
- Mirror Therapy is a rehabilitation approach for stroke patients that uses a mirror to create the illusion of movement in their impaired arm by showing the movement of the unaffected arm.
- Recent research explores combining Mirror Therapy with immersive virtual reality (VR) technology to enhance therapy using muscle sensors for grasping tasks.
- A study involving 18 healthy participants found that while both unimanual and bimanual visual feedback setups are effective, the VR application showed positive usability and minimal side effects, indicating its potential for stroke rehabilitation despite no major performance differences between the two setups.
TMS assessment of corticospinal tract integrity after stroke: broadening the concept to inform neurorehabilitation prescription.

Upper limb actions require intersegmental coordination of the scapula, shoulders, elbows, forearms, wrists, and hand muscles. Stroke hemiparesis, presenting as an impairment of an intersegmentally coordinated voluntary movement, is associated with altered integrity of corticospinal tract (CST) transmission from the motor cortex (M1) to muscles. Motor evoked potentials (MEPs) elicited by M1 transcranial magnetic stimulation (TMS) of "at rest" muscles, or as a backup, during muscle contraction have been used to identify CST integrity and predict the outcome after hemiparesis, under the implicit assumption that MEPs present in only one or two muscles are manifest surrogates of CST integrity for other muscles of the upper limbs.

Movement disorders, such as stroke and amyotrophic lateral sclerosis, result in loss of upper limb function and, hence, severe impairments of bimanual coordination. Although motor imagery is increasingly used to enhance neurorehabilitation, cognitive and neurophysiological parameters that inform effective strategies remain elusive. The aim of the present study is to elucidate the neural dynamics that underlie learning during real and imagined movement using both unimanual and bimanual coordination patterns.

Humans use their arms in complex ways that often demand two-handed coordination. Neurological conditions limit this impressive feature of the human motor system. Understanding how neuromodulatory techniques may alter neural mechanisms of bimanual coordination is a vital step towards designing efficient rehabilitation interventions.
