A functional electrical stimulation system improves knee control in crouch gait

BACKGROUND Crouch gait is a major sagittal plane deviation in children diagnosed with cerebral palsy (CP). It is defined as a combination of excessive ankle dorsiflexion and knee and hip flexion throughout the stance phase. To the best of our knowledge, functional electrical stimulation (FES) has not been used to decrease the severity of crouch gait in CP subjects and assist in achieving lower ...

Human Gait Control Using Functional Electrical Stimulation Based on Controlling the Shank Dynamics

Introduction: Efficient gait control using Functional Electrical Stimulation (FES) is an open research problem. In this research, a new intermittent controller has been designed to control the human shank movement dynamics during gait. Methods: In this approach, first, the three-dimensional phase space was constructed using the human shank movement data recorded from the healthy subjects. Then...

Gait Restoration by Functional Electrical Stimulation

For over 40 years, research labs have been developing gait assist systems that use electrical stimulation of muscle to restore function to limbs paralyzed as a result of spinal cord injury. The concept of functional electrical stimulation (FES) is simple, but realization is challenging. While there are some similarities between FES-aided gait and a bipedal robot walking machine, there are also ...

Effects of Functional Electrical Stimulation on Gait in Cerebral Palsy

Several authors have reported functional and therapeutic benefits after the application of electrical stimulation to children with neurological disorders (1-3). A functional movement can be induced by electrical neuromuscular stimulation of the paralysed muscles with intact excitability of their peripheral innervation. A long-term use of electrical neuromuscular stimulation can strengthen the w...

Improved ankle and knee control with a dual-channel functional electrical stimulation system in chronic hemiplegia. A case report.

The aim of tis report is to describe the effects of a dual-channel functional electrical stimulation (FES) system applied daily as an orthotic device to the dorsiflexors and hamstrings muscles in a subject with chronic hemiparesis. Prior to the application of FES, the patient's gait was characterized by a footdrop and knee hyperextension during stance. measurements of gait performance were coll...
