Further study details as provided by Rainbow Medical:

Primary Outcome Measures:
  • The severe adverse events rate within the procedure [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Improvement in tremor symptoms during the procedure [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks ] [ Designated as safety issue: No ]

    Improvement after treatment in ET and PD tremor symptoms in comparison to baseline, as measured by change in:

    • UPDRS part III scale
    • Clinical Tremor Rating Scale
    • Accelerometer values
    • Patient tremor evaluation diary

Estimated Enrollment: 15
Study Start Date: October 2013
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Stimulation procedure
Stimulation procedure
Procedure: Stimulation procedure

Detailed Description:

This study will evaluate the effect of Rainbow Medical's stimulation procedure methodology that will be applied temporarily to patients suffering of tremor.

This will be evaluated by assessment of reduction of tremor using accelerometer measurements, patient tremor evaluation diary, tremor rating scale, and the Unified Parkinson's Disease Rating Scale (UPRDS) part III.In addition,tasks for patient with tremor will be conducted before during and after the treatment. The above measurements will provide data on the stimulation procedure effect as compared to baseline.
