The purpose of this study is to assess the safety and the preliminary efficacy of treatment by the VascuActive device on peripheral diabetic neuropathy, and to correlate this effect with physiologic changes.

Patients will undergo a 4-week period of home treatment by the VascuActive device, and will be monitored during this period and during a two-month follow-up period for the efficacy of the device in reducing neuropathic pain, sensation impairment and other signs and symptoms.

Further study details as provided by VascuActive LTD:

Primary Outcome Measures:
  • Diabetic neuropathic pain [ Time Frame: 2, 4, 5, 12 weeks from start of treatment ]
    Pain will be assessed by several tools, including 11-point numeric scale, Brief Pain Inventory questionnaire, Pain relief scales (visual analog, categorical)

Secondary Outcome Measures:
  • Sensation impairment [ Time Frame: 2, 4, 5, 12 weeks from start of treatment ]

    Touch sensation will be examined by the 5.07 Semmes-Weinstein monofilament (10 grams).

    Vibraion sensation will be examined by a 128Hz fork.

  • Nerve conduction velocity [ Time Frame: 4, 12 weeks from start of treatment ]

Estimated Enrollment: 15
Study Start Date: March 2011
Estimated Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: VascuActive Treatment Device: VascuActive device
self treatment by the patient, for 4 weeks, 3 sessions per day, approximately 30 minutes per session
