Therapy to Improve Reaching Movement in Upper Limb

Phase N/A Results N/A

Trial Description

Strokes are caused by a bleed in the brain and can be life threatening. One common consequence is upper limb impairment. This causes stroke patients to be unable to use their arms and upper body to do simple tasks such as reaching or grasping. Currently, people with stroke undergo rehabilitation, which is usually done through a physical and occupational (daily living skills) therapies to improve their mobility (movement) with their upper limbs. However, this kind of treatment has limitations and often cannot help patients regain total mobility. There are alternative rehabilitation treatments that use new methods and technologies that may be able to help patients with stroke. Neuromodulaton therapies using brain-computer interfaces (BCI), which connects brain signals directly to a computer, have the potential to help patients. This type of therapy uses assistive devices such as electrical stimulation (electrical shocks or waves) and robots to help restore function to the areas affected by stroke. The aim of this study is to evaluate and the potential benefits that can be achieved by using assistive devices in rehabilitation sessions with stroke patients.

Conditions

Interventions

  • Neuromodulation electroencephalographic signals and functional electrical stimulation based Other
    Other Names: Neuromodulation
    Intervention Desc: First, the subject performs twenty reaching movements without assistance with the damaged arm resting on a robot (ArmeoSpring), with the aim of finding the Contingent Negative Variation (CNV). Then, he or she executes five courses of twenty movements receiving functional electrical stimulation (FES), either at the moment in which he or she wishes to move (experimental group), or half a second before or after (control group).
    ARM 1: Kind: Experimental
    Label: Experimental group
    Description: The subject receives the Functional Electrical Stimulation (FES) when he or she has the intention to move. It is obtained through electroencephalography.
    ARM 2: Kind: Experimental
    Label: Control group
    Description: The subject receives the Functional Electrical Stimulation (FES) after o before (0.5 seconds) when he or she has the intention to move. It is obtained through electroencephalography.
