Equipamentos para estimulação elétrica funcional

Abstract

Title: Functional Electrical Stimulation (FES) Aims: Evaluation of FES technique in patients with different neurologic pathologies, using devices developed by the Biomedical Engineering Division - HCPA. The basic aims are: muscular spasticity reduction, muscle strengthening and gait pattern improvement. Material: FES-I1 portable, 2 channels, Biomedical Engineering Division – HCPA FES-I1 clinicai, 2 channels, Biomedical Engineering Division - HCPA These FES equipments have the following characteristics: Channels: 2 isolated channels Current output amplitude: O to 80 mA Pulse width: 100 to 700 Pulse frequency: 10 to 60 Hz Burst controls: Atack, sustain, decay and resting times: adjustables Automatic and manual control Automatically assisted human gait using two specially designed foot-palms. Mehtods: Lubljana method. Periodic sessions of 10 minutes each applied to selected patients. The results were evaluated according to gait pattern analysis and clinicai examinations of the stimulated muscles. Results: Muscular spasticity reduction: 27/33 81,8 % patients Gait pattern improvement: 14/19 73,7 % patients Shoulder pain relief: 12/12 100 % patients Conclusions: Functional Electrical Stimulation (FES) technique is an effective means of obtaining muscular contractions of the paralyzed limbs, and, if possible, restoring controllable limb function in high-level spinal cord injury patients. FES is clinically indicated for patients with: spinal cord injury4, cerebrovascular disorders (stroke), central paralysis, brain injury, multiple sclerosis, etc ... 5.
