Abstract

A functional electrical stimulation system (1) for correction of drop-foot, comprising: a device (3) to be placed on a paretic leg, provided with a plurality of multi-pad electrodes (315) on one side (31), at least one of said electrodes (315) being configured to provide a stimulating electric signal on the point of the leg on which it is positioned, wherein said corresponding stimulating electric signals form a stimulation pattern; and at least one sensor (8) to be positioned on either said leg or corresponding foot, the sensor (8) being configured to, measure information during movement and emit sensor signals indicative thereof. The system further comprises means (6) for calculating a foot trajectory from said sensor signals, for detecting gait phase from said foot trajectory, for evaluating the quality of gait from said foot trajectory and for, if the quality of gait is below a certain threshold, modifying said stimulation pattern; and means (7) for selectively activating at least one of said electrodes (315) according to said modified stimulation pattern. Method, use and computer program product.

Description

Technical field [0001] The present invention relates to the field of functional electrical stimulation (FES) devices, and in particular, to FES devices and methods for treating drooping foot disorders. Background technique [0002] Drooping feet, also known as foot drooping, refers to the inability or difficulty to move the ankles and toes upward while walking. In other words, drooping feet refers to the difficulty of lifting the front part of the foot. It is not a disease in itself: it is often evidence of an underlying neurological disorder (stroke, spinal cord injury, cerebral palsy, or peripheral nerve injury). Depending on the severity of the drooping foot, its impact ranges from unsightly walking and increased energy consumption to increased risk of falling or even inability to walk at all. Sagging feet can be temporary or permanent. [0003] The drooping foot is the result of the interruption or cutting of the communication path between the brain, motor nerves and leg mus...
