Gondola Mechanism of Action

January 13, 2023 updated by: David Putrino, Icahn School of Medicine at Mount Sinai

Mechanism of Action for Effects From Automated Mechanical Peripheral Stimulation

This study will investigate the clinical, functional and neurophysiological effects of automated mechanical peripheral stimulation (AMPS) via the Gondola device administered to patients with chronic stroke, cerebral palsy and Parkinson's Disease. Results will be collected using standardized outcome measures and a transcranial magnetic stimulation assessment protocol including electrical stimulation and electromyographic recording.

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.

Detailed Description

The working hypothesis for this pre-post intervention study is that one session of AMPS will increase voluntary motor drive of the plantar-flexors (soleus) muscle. The primary outcome measure will be maximum voluntary contraction (MVC) of the soleus (measured by electromyography, EMG); the secondary outcome will be the MVC of the antagonist muscle, the tibialis anterior. Data will be collected before the first session compared to directly after. The same measures in sham-stimulated and healthy volunteers will serve as controls.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

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.
Active Comparator: Real AMPS
AMPS therapy consists of mechanical stimulations applied to two specific points on both feet: the tip of the big toe (hallux) and the first metatarsal joint.
Device: Gondola AMPS
One treatment session lasts about two minutes and consists of the application of a mechanical pressure pulses on each of the points, one after the other, for a set duration (a few seconds), which is repeated several times in sequence.
Other Names:
  • Automated Mechanical Peripheral Stimulation
Sham Comparator: Sham AMPS
AMPS therapy applied to two non-specific points on both feet.
Device: Gondola AMPS
One treatment session lasts about two minutes and consists of the application of a mechanical pressure pulses on each of the points, one after the other, for a set duration (a few seconds), which is repeated several times in sequence.

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 in Soleus MVC
Time Frame: pre and post-AMPS (baseline and 2 minutes)
maximum voluntary contraction of the soleus muscle (measured by EMG)
pre and post-AMPS (baseline and 2 minutes)

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 in Tibialis anterior MVC
Time Frame: pre and post-AMPS (baseline and 2 minutes)
maximum voluntary contraction of tibialis anterior (measured by EMG)
pre and post-AMPS (baseline and 2 minutes)
Change in 10 meter walk test
Time Frame: pre and post-AMPS (baseline and 2 minutes)
self-selected pace to determine gait speed
pre and post-AMPS (baseline and 2 minutes)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
