About this study
Official title: Contralaterally Controlled FES Versus Cyclic NMES for Hand Function After Stroke
After a stroke, it is very common to lose the ability to open the affected hand. The purpose of this study is to compare the effects of three different therapies on recovery of hand function after stroke and determine if any one is better than the other.
Read the detailed description
A single-blinded randomized controlled trial will be carried out to assess and compare the effects of 12 weeks of Contralaterally Controlled Functional Electrical Stimulation (CCFES), Cyclic Neuromuscular Electrical Stimulation (cNMES), and Task Oriented Training. Dexterity, upper limb impairment, and activity limitation will be assessed at 0 (baseline), 12 (end of treatment), and 36 weeks. The treatment dose will be the same for all three groups: 10 sessions per week of self-administered treatment at home plus 2 sessions per week of group-specific occupational therapy in the lab.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Electrical StimulatorDevice
An electrical stimulator will be used to deliver electrical current through surface electrodes to produce hand opening by making the paretic finger and thumb extensor muscles contract. The stimulator can be programmed to turn on and off in a repetitive cyclic fashion (i.e., cNMES) or be programmed to deliver stimulation with an intensity that corresponds to the opening of a glove instrumented with sensors and plugged into the stimulator (i.e., CCFES).
Occupational TherapyBehavioural
Task practice that requires movement and use of the paretic hand under the guidance of a trained therapist.
| Study group | Role | What they receive |
|---|---|---|
| CCFES | Experimental | Contralaterally Controlled Functional Electrical Stimulation (CCFES) uses an electrical stimulator and surface electrodes placed over the paretic finger and thumb extensors to deliver stimulation with an intensity that is proportional to the degree of opening of the contralateral unimpaired hand wearing an instrumented glove. Thus, volitional opening of the nonparetic hand produces stimulated opening of the paretic hand. During the lab visits, participants in the CCFES group will use CCFES to assist hand opening during occupational therapy task practice. During their home sessions, participants in the CCFES group will use CCFES to perform hand opening exercise. Receives: Device: Electrical Stimulator; Behavioral: Occupational Therapy |
| cNMES | Active comparator | Cyclic Neuromuscular Electrical Stimulation (cNMES) uses an electrical stimulator and surface electrodes over the paretic finger and thumb extensors to deliver electrical stimulation to open the weak hand. The stimulation automatically turns on and off causing the weak hand to open repetitively for several seconds at a time. During the lab visits, participants in the cNMES group will receive occupational therapy task practice. During their home sessions, participants in the cNMES group will use cNMES to perform hand opening exercise. Receives: Device: Electrical Stimulator; Behavioral: Occupational Therapy |
| Task Oriented Therapy | Active comparator | Task Oriented Therapy (TOT) focuses on practicing using the weak hand to practice activities of daily living tasks. During the clinic visits, participants in the TOT group will receive occupational therapy task practice. During their home sessions, participants in the TOT group will practice using their hand to complete a list of tasks given to them by the therapist to ensure that the participant receives a high dose of task practice. Receives: Behavioral: Occupational Therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Box and Blocks Test (BBT) at 6 Months Post-Treatment
The BBT is a measure of hand dexterity. It is a count of how many blocks a patient can pick up, move over a barrier, and release in 60 seconds. The higher the score, the better the motor recovery.
Measured: Baseline to 6 months post-treatment
Secondary outcomes (4)
Change in Upper Extremity Fugl Meyer (UEFM) at 6 Months Post-Treatment
The UEFM is a measure of upper limb motor impairment with a minimum score of 0 and maximum score of 66. The higher the score, the better the motor recovery.
Measured: Baseline to 6 months post-treatment
Change in Action Research Arm Test (ARAT) at 6 Months Post-Treatment
The ARAT is a measure of arm and hand function with a minimum score of 0 and maximum score of 57. The higher the score, the better the motor recovery.
Measured: Baseline to 6 months post-treatment
Change in Stroke Upper Limb Capacity Scale (SULCS) at 6 Months Post-Treatment
The SULCS is a measure of upper limb capacity with a minimum score of 0 and maximum score of 10. The higher the score, the better the motor recovery.
Measured: Baseline to 6 months post-treatment
Responder Rate
Proportion of participants who had a gain of at least 6 points on the UEFM
Measured: Baseline to 6 months post-treatment

What does the primary outcome measure?
Change in Box and Blocks Test (BBT) at 6 Months Post-Treatment (time frame: Baseline to 6 months post-treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03574623, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2026.
