Self-modulated Functional Electrical Stimulation in Chronic Stroke Patients With Severe and Moderate Upper Limb Paresis (SM-FES)

May 22, 2023 updated by: Intento SA

Self-modulated Functional Electrical Stimulation in Chronic Stroke Patients With Severe and Moderate Upper Limb Paresis: A Multi-Centre, Single-Blind, Randomized Parallel Study

The study aims at demonstrating the efficacy of self-modulated functional electrical stimulation (SM-FES) in promoting upper-limb (UL) motor recovery in chronic stroke patients with severe and severe-moderate paralysis.

The effect of such experimental therapy will be compared to dose-matched, goal-oriented standard care (SC).

SM-FES consists of intensive, goal-oriented, repetitive functional exercises assisted by electrical stimulation. The patient actively self-administers the electrical stimulation on the impaired limb by controlling the electrical stimulation device with the non-impaired hand.

The duration of the intervention is 90 min per day, 5 days per week, for 2 weeks.

Detailed Description

After the informed consent process, each centre will screen potential participants according to the inclusion and exclusion criteria.

Each recruited participant will be randomly assigned to one group:

  • experimental group - patients will receive self-modulated functional electrical stimulation SM-FES;
  • control group - patients will receive standard care SC.

This first main phase of the study includes 10 days intervention delivered to the two groups and assessments pre-intervention, post-intervention and after 3 months (follow-up).

After the follow-up, participants initially recruited in the control group will be able to enter a secondary exploratory phase and receive further 10 days of treatment with SM-FES.

Inclusion Criteria:

  • diagnosis of one, first-ever ischemic stroke verified by brain imaging (i.e. computed tomography or magnetic resonance imaging);
  • chronic impairment after stroke, i.e. time since event ≥ 6months;
  • severe and severe-moderate upper limb impairment, i.e. FMA-UE score ≤ 34;
  • 18 ≤ age < 80;
  • ability to give consent, understand the device use and follow instructions.

Exclusion Criteria:

  • an unstable recovery stage, measured as a difference between screening and baseline examinations of more than 3 points in the motor part of the FMA-UE scale;
  • contraindications and risk factors to neuromuscular electrical stimulation;
  • severe hemi-spatial neglect or anosognosia involving the affected arm, as determined by the Bells tests (> 6 errors);
  • severe impairment of proprioception, as evaluated from the blinded detection and discrimination of imposed passive movements (≥ 20° extension or flexion) of the finger proximal joint (>3 errors out of 6 mobilisations);
  • severe impairment of tactile sensing in the hand, as assessed by Semmes-Weinstein monofilament test (no detection of the 5.88 size evaluator);
  • excessive spasticity, as indicated by a score > 2 in any of the items of the REsistance to PASsive movement (REPAS) arm subtest;
  • recurrent, moderate to high upper limb pain limiting delivery of rehabilitation dose, i.e. pain at rest and in correspondence of a passive range of motion lower than 50%;
  • botulinum toxin injection into affected upper extremity during 3 months before the study or during the study;
  • history of physical / medical conditions interfering with study procedure, for example shoulder subluxation, upper extremity injury that limits the function of the hand or arm, skin lesion/rash/open wound on the affected upper extremity, or similar;
  • history of neurological condition interfering with study procedure, e.g. Parkinson's disease, progressive brain diseases like dementia and tumours;
  • use of antipsychotic medications;
  • enrolled in the past six months in another study involving drugs, biologics, upper limb experimental therapy, or similar.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Self modulated functional electrical stimulation (SM-FES)
Patients will receive self-modulated functional electrical stimulation SM-FES

The patient actively self-administers the electrical stimulation on the impaired limb by controlling the electrical stimulation device with the non-impaired hand. A device called the Intento PRO will be used to deliver the experimental treatment.

Duration: 90 min per day, 5 days per week, for 2 weeks.

Active Comparator: Standard care (SC)
Patients will receive standard care, dose matched to the experimental group therapy

The patient performs intensive, goal-oriented, repetitive functional exercises.

Duration: 90 min per day, 5 days per week, for 2 weeks.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in the motor part of the Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) scale, calculated from baseline to post-intervention (2 weeks)
Time Frame: From baseline to post-intervention (2 weeks)
The FMA-UE measures the upper limb motor impairment. FMA-UE consists of 33 items. Each item is scored on a 3-point ordinal scale (0, 1, and 2) with 0 generally corresponding to no function, 1 to partial function, and 2 to perfect function. The items are summed to the final maximal score of 66 (no impairment).The FMA may also be divided into shoulder/elbow and wrist/hand sub-scores consisting of 18 and 15 tasks, with a maximum score of 36 and 30, respectively. Higher scores indicate less impairment.
From baseline to post-intervention (2 weeks)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of the Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) scale at 3 months (T3) compared to baseline (T0)
Time Frame: At 3 months (T3) compared to baseline (T0)
The FMA-UE measures the upper limb motor impairment. FMA-UE consists of 33 items. Each item is scored on a 3-point ordinal scale (0, 1, and 2) with 0 generally corresponding to no function, 1 to partial function, and 2 to perfect function. The items are summed to the final maximal score of 66 (no impairment). The FMA may also be divided into shoulder/elbow and wrist/hand sub-scores consisting of 18 and 15 tasks, with a maximum score of 36 and 30, respectively. Higher scores indicate less impairment.
At 3 months (T3) compared to baseline (T0)
Number and proportion of patients with change of at least 5 FMA-UE points from baseline (T0) to 2 weeks (T2) post-intervention and 3 months (T3) follow-up
Time Frame: From baseline (T0) to 2 weeks (T2) post-intervention and 3 months (T3) follow-up
Fugl-Meyer Assessment of the Upper Extremity (FMA-UE).
From baseline (T0) to 2 weeks (T2) post-intervention and 3 months (T3) follow-up
Change of upper limb function measured by the Action Research Arm test (ARAT) from baseline to post-intervention (2 weeks) and to 3 months follow-up
Time Frame: From baseline to post-intervention (2 weeks) and to 3 months follow-up
The ARAT measures of the upper limb function. It contains 19 items grouped into 4 subscales: grasp, grip, pinch and gross motor. In the first 3 subscales, the scale assessed the ability to grasp, move, and release objects of differing size, weight, and shapes. The last subtest evaluates 3 gross movements (place hand behind head, place hand on top of head, and move hand to mouth). Each item is graded on an ordinal scale from 0-3, all of which are summed to yield a score of 0 to 57. Higher scores indicate less impairment.
From baseline to post-intervention (2 weeks) and to 3 months follow-up
Change of perceived upper limb function measured by the Motor Activity Log (MAL) from baseline to post-intervention (2 weeks) and to 3 months follow-up
Time Frame: From baseline to post-intervention (2 weeks) and to 3 months follow-up

The MAL is a measure of perceived upper limb disability in activities of daily living.

The MAL-14 includes 14 items, scored on an 11-point amount of use (AOU) scale (range 0-5) to rate how much the arm is used and an 11-point quality of movement (QOM) scale (range 0-5) to rate how well patients are using their affected upper extremity.

From baseline to post-intervention (2 weeks) and to 3 months follow-up
Change of hand and arm spasticity measured by the REsistance to PASsive movement (REPAS) from baseline to post-intervention (2 weeks) and to 3 months follow-up
Time Frame: From baseline to post-intervention (2 weeks) and to 3 months follow-up
The REPAS consists of several items across different defined joints, each of which are rated according to the Modified Ashworth Scale (MAS) (0 = no increase in muscle tone to 4 = limb rigid in flexion or extension), and includes assessments of the shoulder, elbow, forearm, wrist, finger. A higher score indicates more severe impairment, with a maximum upper limb score of 64.
From baseline to post-intervention (2 weeks) and to 3 months follow-up
