Combined Behavioral Approaches With Functional Electrical Therapy in Stroke Rehabilitation

10. februar 2015 oppdatert av: Chang Gung Memorial Hospital

Combined Behavioral Approaches With Functional Electrical Therapy in Stroke Rehabilitation: Effects on Motor Control, Motor Impairment, Daily Function and Community Reintegration

This project attempts to perform a randomized controlled trial to verify the efficacy and motor control mechanism of the proposed combined functional electrical therapy with distributed constraint-induced therapy or with robot-assisted Bilateral training.

Studieoversikt

Detaljert beskrivelse

Two theory-based, task-oriented approaches are distributed CIT (dCIT) and robot-assisted Bilateral training(BAT). CIT/dCIT involves massed practice of the affected arm and restraint of the unaffected arm. BAT involves repetitive practice of symmetrical bilateral movements on robot. Both are evident to improve motor performance, motor control or daily function in high functioning patients. These dCIT and BAT have their own limitations for motor-deficit rehabilitation after stroke, i.e. only appropriate for high-functioning or mildly motor impaired patients. Functional electrical therapy, an innovative technology, is proposed as an adjunct to these behavioral approaches to assist in movement execution. Functional electrical therapy is used to increase the electric activity of muscles for movement and the active range of motion in low functioning patients. Combining functional electrical therapy into CIT or BAT may extend the utility of these two behavioral approaches beyond patients with mild motor deficits and could expedite the progress of motor recovery. This project attempts to perform a randomized controlled trial to verify the efficacy and motor control mechanism of the proposed combined functional electrical therapy with dCIT or with BAT.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Combined dCIT with FET
Combined distributed constraint induced therapy with functional electrical therapy
This dCIT group focuses on restriction on movement of the unaffected hand by placement of the hand in a mitt for 6 hours/day and intensive training of the affected upper extremity in functional tasks 1.5 hours/weekday, for 4 weeks. The level of challenge will be adapted based on patient ability and improvement during training. Patients will be encouraged to initiate the designed therapeutic functional activities.

Eksperimentell: Combined BAT with FET
Combined bilateral arm treatment with functional electrical therapy
Andre navn:
  • FES
The BAT group concentrates on the simultaneous movements of both the affected and unaffected upper extremity on robot for 1.5 hours/day, 5 days/week for 4 weeks.
Andre navn:
  • bilateral arm training
Aktiv komparator: Control intervention group
Control intervention
The conventional intervention group is designed to control for the duration and intensity of patient-therapist interactions and therapeutic activities (1.5 hours/day, 5 days/week, for 4 weeks). Therapy in the control intervention group will involve training for coordination, balance, and movements of the affected upper extremity, as well as compensatory practice on functional tasks with the unaffected upper extremity or both upper extremities.

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Movement time (MT)
Tidsramme: Baseline and change from baseline in MT at 4 weeks
The movement time is collected by a 7-camera motion analysis system (VICON MX 3-D, Oxford Metrics Inc., Oxford, UK) from unilateral and bilateral reaching tasks of pressing the desk bell. MT is the interval between movement onset and offset.
Baseline and change from baseline in MT at 4 weeks
Total displacement (TD)
Tidsramme: Baseline and change from baseline in TD at 4 weeks
The movement time is collected by a 7-camera motion analysis system (VICON MX 3-D, Oxford Metrics Inc., Oxford, UK) from unilateral and bilateral reaching tasks of pressing the desk bell. TD refers to the path of a hand in three-dimensional space and is a measure of trajectory smoothness.
Baseline and change from baseline in TD at 4 weeks
Percentage of peak velocity (PPV)
Tidsramme: Baseline and change from baseline in PPV at 4 weeks
The movement time is collected by a 7-camera motion analysis system (VICON MX 3-D, Oxford Metrics Inc., Oxford, UK) from unilateral and bilateral reaching tasks of pressing the desk bell. The PPV reflects the duration of the acceleration phase relative to the deceleration phase and indicates the type of movement strategy selected for a motor action.
