Neural coupling between upper and lower limbs during recumbent stepping.
During gait rehabilitation, therapists or robotic devices often supply physical assistance to a patient's lower limbs to aid stepping. The expensive equipment and intensive manual labor required for these therapies limit their availability to patients. One alternative solution is to design devices where patients could use their upper limbs to provide physical assistance to their lower limbs (i....
متن کاملNeural Coupling between the Upper and Lower Limbs in Individuals with Incomplete Spinal Cord Injury
Growing evidence suggests that there are spinal connections between upper limb motor neurons and lower limb motor neurons in humans that facilitate coordinated interlimb movements (Zehr and Duysens, 2004). Upper limb muscle activation has been shown to facilitate lower limb muscle activation during passive locomotor-like movements of the lower limbs in neurologically intact individuals (Ferris ...
متن کاملPeripheral muscle dysfunction in COPD: lower limbs versus upper limbs.
In patients with COPD, the degree of functional impairment appears to differ between the upper and lower limbs. Significant dyspnea and fatigue have been reported by these patients when performing tasks with unsupported upper limbs and two mechanisms have been proposed to explain this fact: neuromechanical dysfunction of respiratory muscles; and changes in lung volume during such activities. Th...
متن کاملUpper and lower limb muscle activation is bidirectionally and ipsilaterally coupled.
PURPOSE There are neural connections between the upper and lower limbs of humans that enable muscle activation in one limb pair (upper or lower) to modulate muscle activation in the other limb pair (lower or upper, respectively). The aims of this study were to extend previous findings regarding submaximal exercise to maximal effort exercise and determine whether there is an ipsilateral or contr...
متن کاملLocomotion in Parkinson's disease: neuronal coupling of upper and lower limbs.
Quadrupedal limb coordination during human walking was recently shown to be upregulated during obstacle stepping. An anticipatory activity of coupled cervico-thoraco-lumbar interneuronal circuits is followed by an appropriate executory activation of leg and arm muscles during task performance. This mechanism was studied in subjects with Parkinson's disease and age-matched controls walking on a ...
