44

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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Ischemic stroke according to ICD 10 I61-I69
  • Deficit still existing (Rankin score of at least 1 at inclusion)
  • Age >= 18, <=80
  • Existing declaration of consent

Exclusion Criteria:

  • Pregnancy
  • Lacking capacity for consent

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

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: Stimulation
During motor training participants in the stimulation arm receive vibro-tactile feedback applied to their fingers when touching an object as measured by force-sensing resistors mounted to the fingertips.
Device: Vibro-tactile stimulation
Vibro-tactile stimulation will be administered to the fingers of the participants via C3 tactors (diameter: 2.03 cm, height: 0.64 cm, operating frequency: 180-320 Hz, see https://www.eaiinfo.com/tactor-info/). Vibro-tactile stimulation will be triggered by force-sensing resistors (TEA CAPTIV T-SENS FSR, see https://www.teaergo.com/products/tea-captiv-t-sens-fsr/).
Placebo Comparator: Control
The control group receives the same motor training with the same derives (force-sensing resistors, vibro-tactile stimulators) mounted to the hands but receives no stimulation.
Other: Placebo Control
Devices mounted, no stimulation

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
Change from baseline in Action Research Arm Test (ARAT)
Time Frame: One day before (baseline) and one day after seven days of motor training
The Action Research Arm Test (ARAT) is a 19 item observational measure to assess upper extremity performance (coordination, dexterity and functioning). Items comprising the ARAT are categorized into four subscales (grasp, grip, pinch and gross movement) and arranged in order of decreasing difficulty, with the most difficult task examined first, followed by the least difficult task. Task performance is rated on a 4-point scale, ranging from 0 (no movement) to 3 (movement performed normally). Scores may range from 0-57 points, with higher points indicating better performance.
One day before (baseline) and one day after seven days of motor training
Change from baseline in Nine-hole peg Test (NHPT)
Time Frame: One day before (baseline) and one day after seven days of motor training
A timed measure of fine manual dexterity where the patient is instructed to first take nine pegs out of a container and place them afterwards back into the empty holes of the container as quickly as possible.
One day before (baseline) and one day after seven days of motor training

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
Change from baseline in Fugl-Meyer Assessment for upper extremity (FMA-UE)
Time Frame: One day before (baseline) and one day after seven days of motor training
The section motor function of upper limb is one of five domains, a three-point scale is used for rating performance as 0=cannot perform, 1=performs partially and 2=performs fully, max. possible score: 66 points.
One day before (baseline) and one day after seven days of motor training
Change from baseline in Stroke Impact Scale (SIS)
Time Frame: One day before (baseline) and one day after seven days of motor training
Measurement of subjective stroke-specific health status, 64 items in eight domains, domain scores range between 0-100, with higher scores represent better health status.
One day before (baseline) and one day after seven days of motor training
Change from baseline in National Institutes of Health Stroke Scale (NIHSS)
Time Frame: One day before (baseline) and one day after seven days of motor training
The National Institutes of Health Stroke Scale, NIHSS, is a score system to quantify the impairment caused by a stroke. The sum of the values from the investigations results in a maximum of 42 points. The higher the score, the more extensive the stroke.
One day before (baseline) and one day after seven days of motor training
Change from baseline in Modified Rankin Scale (mRS)
Time Frame: One day before (baseline) and one day after seven days of motor training
The modified Rankin scale (MRS) is a standardized measure that describes the extent of disability after a stroke. It ranges from 0 (no symptoms) to 6 (death due to stroke).
One day before (baseline) and one day after seven days of motor training
