Study summary

This is a double blind randomized clinical trial to evaluate the effect of radial shock waves on functional recovery of the upper limb of patients with sequelae of ischemic strokes in the territory of the middle cerebral artery. A total of 20 patients will be enrolled and will undergo motor, functional and cortical excitability evaluations before and after four weekly sessions of radial shockwaves. 5,000 pulses with a frequency of 15 Hz and 3.5 to 4 bar of air pressure will be applied to the active group, resulting in an energy flux density (EFD) of approximately 0.07 mJ/mm2. The sham group will receive identical treatment, except for the fact that no energy flux will be applied.

Study arms

  • Experimental
    Active Radial Shockwave

    Every patient will receive 5,000 continuous pulses per treatment session, at 3.5 to 4 bar air pressure (resulting in an energy flux density \[EFD\] of approximately 0.07 mJ/mm2) and at 15Hz frequency. A total of 4 sessions will be performed.

    Device: Active Radial Shockwave

  • Sham comparator
    Sham Radial Shockwave

    Every patient will receive 5,000 continuous pulses per treatment session, without air pressure (resulting in no EFD) and at 15Hz frequency. A total of 4 sessions will be performed.

    Device: Sham Radial Shockwave

Interventions

  • DeviceActive Radial Shockwave

    Four weekly sessions of active radial shockwave treatment.

  • DeviceSham Radial Shockwave

    Four weekly sessions of sham radial shockwave treatment.
