About this study

In this study, an FDA-cleared device and type of treatment called "AMES," which stands for Assisted Movement with Enhanced Sensation, will be used to determine whether sensation in the upper limb of individuals with incomplete spinal cord injuries, acquired brain injury, or stroke improves along with movement through treatment. We hypothesize that measureable improvement in the sensation of the upper limb will precede improvement in functional movement.

Read the detailed description

The AMES device performs tests of sensorimotor impairment as well as delivering therapy. In this study, we are testing 2 additional diagnostic tests (i.e., Joint Position Test and "Frisbee" Test), both of proprioception, in order to determine which of the two is the best test of proprioception. Our hypotheses are: (1) both sensation and movement recover with AMES treatment, (2) sensory recovery precedes that of movement, (3) robotic delivery of the Joint Position Test produces more reliable test results than does manual delivery of this test, and (4) the Frisbee Test results will parallel those of the Joint Position Test.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AMES TherapyDevice

    During the therapy session, the AMES device rotates the hand into flexion and extension, while the patient assists with this motion, as possible. At the same time, the AMES device provides sensory stimulation by vibrating the tendons of muscles stretched by the movement. The vibratory stimulus switches from one side of the limb to the other when the rotation reverses direction so that the sensory stimulation remains functionally related to the movement. The subject will receive visual bio-feedback of their contribution to the motor movement.

Study groups in NCT01974635
Study groupRoleWhat they receive
AMES Therapy and DiagnosticExperimentalDuring treatment, the AMES device rotates the hand, into flexion and extension, while the patient assists with this motion,and while the lengthening muscle(s) are vibrated mechanically. At the end of the treatment, several diagnostic tests are performed to measure the participant's level of proprioceptive perception. This study provides for 25 AMES treatments and diagnostic tests over 8-13 weeks, at a rate of 2-3 sessions per week.
Receives: Device: AMES Therapy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Joint Position Test - AMES Device

    Testing proprioceptive sensation, the subject, with eyes closed, attempts to identify verbally the direction of motion (i.e., flexion or extension) as the AMES device randomly moves the subject's thumb and fingers, or the whole hand, into flexion and extension.

    Measured: Immediately after each treatment on the AMES Device

Secondary outcomes (1)
  1. Frisbee Test - Device

    Testing proprioceptive sensation, the AMES device moves the subject's wrist through a 30 degree range, at variable speeds, as the subject attempts to identify when their wrist reaches a particular target, either by opening contact between the thumb and index finger (if possible) or blinking the eyes. The subject receives feedback about the accuracy of the testing.

    Measured: After each treatment on the AMES device.

Questions about this trial

What is this clinical trial studying?

A study testing AMES Therapy in people with Spinal Cord Injury and Stroke, run by Oregon Health and Science University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 13 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Joint Position Test - AMES Device (time frame: Immediately after each treatment on the AMES Device). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01974635, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jun 2019.
