About this study

Official title: Can Upper Limb Robotic Rehabilitation Plus Muscle Vibration Improve Motor Function? A Pilot Study

Muscle vibration (MV) has been suggested as a useful non-pharmacological approach to control spasticity. Armeo Power® (AP) is a robotic exoskeleton for rehabilitation allowing early rehabilitation treatment. The objective of our study was to determine whether AP training coupled with MV applied on antagonist muscles of the spastic upper limb (UL) can reduce the spasticity of agonist muscles. We enrolled 20 chronic post-stroke patients, who underwent 40 daily sessions of AP training. Ten subjects (group-A) received muscle MV (on triceps brachii, deltoid, and supraspinatus), whereas the other 10 (group-B) underwent a sham vibration.

What participants receive

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

  • ArmeoP+real MVDevice

    All the subjects assigned to the experimental received a focal belly-muscle vibration on the spastic antagonist muscles (i.e. triceps brachialis-TB, deltoid-DE, and supraspinatus-SS) during shoulder abduction and elbow extension. MV was delivered by a pneumatic vibrator powered by compressed air (Vibraplus; @Circle, San Pietro in Casale, Italy) (fig. 2) wired to appropriate-muscle probe diameter (up to 2cm2). MV was set at a frequency of 80Hz and an individually adjusted vibration amplitude (approximately 2mm in indentation depth, mean pressure of 250mBar, which effectively induce inhibition of the monosynaptic reflex) so that it was just below the threshold for perceiving an illusory movement. We chose such set up to avoid any signs of muscle contraction potentially reflecting either possible voluntary movement or occurrence of the tonic vibration reflex (TVR).

Study groupRoleWhat they receive
ArmeoP+real MVExperimentalThe patients underwent forty 1h Armeo-P training sessions (i.e. five times a week for eight consecutive weeks). During the first session, the device was adjusted to the patient's arm size and the angle of suspension. The working space and the exercises were selected once the UL had been fitted with the system. All the subjects in the arm received a focal belly-muscle vibration on the spastic antagonist muscles (i.e. triceps brachialis-TB, deltoid-DE, and supraspinatus-SS) during shoulder abduction and elbow extension. MV was delivered by a pneumatic vibrator powered by compressed air, wired to appropriate-muscle probe diameter (up to 2cm2). MV was set at a frequency of 80Hz and an individually adjusted vibration amplitude so that it was just below the threshold for perceiving an illusory movement. The investigators chose such set up to avoid any signs of muscle contraction potentially reflecting either possible voluntary movement or occurrence of the tonic vibration reflex (TVR).
Receives: Device: ArmeoP+real MV
ArmeoP+ Sham MVActive comparatorThe patients underwent the same Armeo-P trainingas the experimental group. Only the vibration protocol was didderent. Indeed, in the control group a sham vibration was used, while in the experimental group, patients underwent a real one. Sham vibration was delivered to the control group using the same procedure of the experimental group;however, vibration intensity was subthreshold (i.e. 50mBar below the threshold).
Receives: Device: ArmeoP+real MV

What is being measured

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

  1. Assessment of spasticity-MAS

    The primary outcomes consisted in the effects of MV and Armeo Power® on spasticity by a clinical (MAS from spastic agonist muscles causing arm adduction, inward rotation, and flexion, and forearm flexion)

    Measured: Six months

Secondary outcomes (1)
  1. Fugl-Meyer Assessment of UL motor recovery after stroke -FMA

    The investigators measured the effects of MV and Armeo Power® on UL motor function impairment (measured by Fugl-Meyer Assessment of UL motor recovery after stroke -FMA).

    Measured: Six months

Questions about this trial

What is this clinical trial studying?

A study testing ArmeoP+real MV in people with Stroke, run by IRCCS Centro Neurolesi Bonino Pulejo.

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 4 inclusion and 7 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: finished, as of the sponsor's last update on 12 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Assessment of spasticity-MAS (time frame: Six months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 12 Apr 2017.
