Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to examine the effects of passive vibration (PV) in improving balance and sensation in patients with diabetic peripheral neuropathy (DPN).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study involves the following:

* Visit 1:
* Particpant's age, height, gender, and weight will be collected.
* Participant will fill out a questionnaire to assess participant's nerve function. This process will take approximately 2.5 minutes.
* Investigator will measure participant's balance, sensation, and skin blood flow (SBF).
* After completing the tests, participant will be randomly assigned by the computer to either the treatment group or control group.
* The treatment group will receive a passive vibration treatment for 15 minutes twice a week for 4 weeks.
* The control group will not receive any treatment and they will continue their usual lifestyle.
* Visit 2 through 8:
* The treatment group will receive a passive vibration for 15 minutes followed by SBF measurement.
* The control group will continue their usual lifestyle.
* In the fifth session, the treatment and control groups will come back for tests.
* Visit 9 (follow-up):

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

passive vibration group

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.

Group Type EXPERIMENTAL

passive vibration

Intervention Type OTHER

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).

no passive vibration group

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 .

Group Type ACTIVE_COMPARATOR

no passive vibration

Intervention Type OTHER

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