Assessment of a Upper Limb Robotic Device in Stroke Patients

March 12, 2018 updated by: University of Sao Paulo General Hospital
The objectives of this phase II clinical study are: evaluate the efficacy, safety, patient adeherence and clinical applicability of a new robotic device for patients with stroke at a physical rehabilitation institution (Instituto de Medicina Física e Reabilitação do Hospital das Clínicas da Universidade de São Paulo - IMREA HCFMUSP - Rede de Reabilitação Lucy Montoro, unidade Vila Mariana). Methods: 10 patients with stroke diagnosis and Fugl-Meyer score ranging from 34 to 55 will be selected to be included in the study. After signing the informed consent form and being assessed by the baseline evaluations, they will undertake 18 sessions of robotic therapy, which in its turn will be prescribed three times a week. After this period, the patients will be evaluated for future comparison of both the pre-treatment and final assessments.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inlcusion Criteria:

  1. Between 40 and 65 years.

  3. Clinical and radiological diagnosis of ischemic stroke in the vascular territory of the middle cerebral artery or anterior cerebral artery.
  4. Clinical assessment of disability with diagnosis of right or left hemiparesis.
  5. Onset between 24 and 36 months.
  6. Clinical stability verified in medical evaluation.
  7. Spasticity less than or equal to 2 in Modified Ashworth Scale.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Robotic Therapy
After consent, 10 participants will be included in a training program, as described below: 1º session will be robotic calibration and assessment; the following 18 sessions will be conducted the robotic therapy for upper limbs, three times a week. Each session will have a total duration of 55 minutes, including initial patient positioning and adjusting and after a sequence of game tasks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Fugl Meyer Assessment Upper Limb (FMA-UL)
Time Frame: Mean change from baseline at six weeks (19 sessions of robotic therapy).
FMA-UL evaluates the recovery of the hemiplegic patient after stroke. It includes the measurement of reflex activity, movement with and without synergy, voluntary movements and coordination of shoulder, elbow, wrist, hand.
Mean change from baseline at six weeks (19 sessions of robotic therapy).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Wolf Motor Function Test (WMFT)
Time Frame: Mean change from baseline at six weeks (19 sessions of robotic therapy).
WMFT evaluates time performance and functional ability in 17 unimanual tasks.

Dynamometry - Grasp and Pinch
Time Frame: Mean change from baseline at six weeks (19 sessions of robotic therapy).

Mean change from baseline at six weeks (19 sessions of robotic therapy).
Patients safety
Time Frame: Adverse effects reported during 6 weeks treatment.
Adverse effects questionnaire applied in each session.
Adverse effects reported during 6 weeks treatment.
Treatment adherence

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Clinical feasibility
Time Frame: Reported during 6 weeks treatment, in each session.
