Outcome Measures

Primary Outcomes (1)

  • Skin blood flow

    Patient will be positioned in prone on a plinth as their skin is marked for blood flow assessment. A 3 cm x 3 cm square shape will be marked on the posterior aspect of the calf (muscle belly) and on the plantar aspect of the first three metatarsal heads. MOOR Full-field Laser Perfusion Image(FLPI) (MOOR FLPI V 2.1, Oxford, England) will be used for measurement of skin blood flow in a patient with DPN, which will be pre-warmed for about 30 minutes. The perpendicular red light laser beam will be used to capture SBF and blood flow is measured in '"Flux" unit.

    Change between Baseline and Week Nine Visit

Secondary Outcomes (1)

  • balance

    at each of the nine visits( 90 minutes each visit: twice per week)

Study Arms (2)

passive vibration group

EXPERIMENTAL

The passive vibration group patients will receive passive vibration (50 Hz, one cycle= 60 seconds working time with 2 seconds rest time) on their calf in supine position for ten minutes. The total number of sessions will be nine. Passive vibration will be given to the treatment group twice a week for four weeks (eight sessions) and the ninth session will be the follow up. At every session, the skin blood flow will be measured before, immediately, and 15 minutes after passive vibration.

Other: passive vibration

no passive vibration group

ACTIVE COMPARATOR

The control group will not receive any treatment and continue their usual lifestyle. Balance, sensory measurement and skin blood flow will be taken at the beginning of the study, prior to the 5th treatment, and 1 week after the last intervention .

Other: no passive vibration

Interventions

The passive vibration is delivered using a Physio Plate (Domino S.R.L, San Vendemiano, Italy). The frequency delivered is 50 Hz for a total number of ten cycles for a period of ten minutes approximately (one cycle= 60seconds working time with 2 seconds rest time).

The control group will not receive any treatment and continue their usual lifestyle.
