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.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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.
Other Names:
  • Automated Mechanical Peripheral Stimulation
