Strategies to Control Robotic Hand Prosthesis Via HD-sEMG and to Restore Sensory Feedback Via TENS

June 27, 2024 updated by: Istituto Nazionale Assicurazione contro gli Infortuni sul Lavoro

Development of Innovative Strategies for the Control of Robotic Hand Prostheses Based on High-density Electromyography and Restitution of Sensory Feedback Via Trans-cutaneous Electrical Stimulation

Upper limb amputation still causes severe disability today; prostheses currently on the market are able to restore partially to the amputee the lost functionality. In addition to the motor capacity of the limb, prosthetic systems should also aim to restore to the sensory information from the surrounding environment during contact with objects. Therefore, it is important to develop bidirectional prostheses. It is thus apparent that the development of new techniques for decoding the efferent channel, such as high-density surface electromyography, and for encoding of the afferent channel afferent, to return multimodal somatosensory sensations of mechanoception, nociception, and thermoception using TENS, isimportant to improve the patient's use of the prosthesis.

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.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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: All participants
Other: Electromyography recording with HD-sEMG
Measurement of muscle electrical signal with HD-sEMG sensors, training of a pattern recognition classifier for hand gesture recognition, verification and comparison with state of the art.
Other: Transcutaneous Electrical Nerve Stimulation (TENS)
Application of TENS by means of non-invasive superifical electrodes on the stump skin of the participants to restore multimodal somatotopical sensations of mechanoception, nociception and thermoception.

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
Improve gestures decoding by means of HD-sEMG decoding algorithms
Time Frame: through study completion, an average of 2 year through study completion, an average of 2 year
The performance of HD-sEMG classifiers with variable number of classes will be evaluated in the offline phase in terms of accuracy of classification and F1-Score.
through study completion, an average of 2 year through study completion, an average of 2 year
Elicit somatic sensations in amputees
Time Frame: through study completion, an average of 2 year through study completion, an average of 2 year
The performance of the stimulation strategy will be evaluated in terms of stimulus discrimination accuracy, a parameter that identifies the number of times the subject correctly reports the type of sensation elicited by the experimenter compared to the total number of stimulations performed.
through study completion, an average of 2 year through study completion, an average of 2 year

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
Increase the number of hand grasps to be classfiied
Time Frame: through study completion, an average of 2 year through study completion, an average of 2 year
To explore the possibility of increasing the number of gestures that can be classified by the developed classification system, compared to the number of gestures that can be reproduced by prosthetic control solutions traditional and to evaluate the intuitiveness in using classifiers to control a polyarticulated prosthesis.
through study completion, an average of 2 year through study completion, an average of 2 year
Development of encoding strategies
Time Frame: through study completion, an average of 2 year through study completion, an average of 2 year
Develop new algorithms for decoding motor intention from the myoelectric signal and new encoding algorithms for the sensory restitution by non-invasive stimulation and to evaluate the intuitiveness of the developed strategies.
