History of Changes
  Purpose

The aim of this study was to determine the effects of 4 Hz and 110 Hz transcutaneous electrical nerve stimulation on the sympathetic nervous system via measuring the sympathetic skin response (SSR) and skin temperature.


Condition Intervention
Effects of TENS on Sympathetic Skin Response
 Device: transcutaneous electrical nerve stimulation

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Double Blind (Subject, Outcomes Assessor)
Primary Purpose: Basic Science
Official Title: The Effects of High and Low Frequency Transcutaneous Electrical Nerve Stimulation on Sympathetic Skin Response and Skin Temperature

Further study details as provided by Shiraz University of Medical Sciences:

Primary Outcome Measures:
  • Changes of sympathetic skin response [ Time Frame: 15 seconds before, just 15 seconds after, and 10 minutes after application of interventions ] [ Designated as safety issue: No ]
    Sympathetic skin response from the simulated (Right) hand was measured 15 seconds before, just 15 seconds after, and 10 minutes after application of interventions.


Secondary Outcome Measures:
  • Changes of skin temperature [ Time Frame: 15 seconds before, just 15 seconds after, and 10 minutes after application of interventions ] [ Designated as safety issue: No ]
    skin temperature of both stimulated (Right) and none stimulated (Left) hand was measured 15 seconds before, just 15 seconds after, and 10 minutes after application of interventions

Study Completion Date: June 2011
Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: electrical nerve stimulation
All subjects participated, randomly, in a 4 Hz transcutaneous electrical nerve stimulation session, a 110 Hz transcutaneous electrical nerve stimulation session, and a control (off-transcutaneous electrical nerve stimulation) session. Each session consisted of a 20- minute stimulation period and a 10-minute follow up period
 Device: transcutaneous electrical nerve stimulation
All subjects participated, randomly, in a 4 Hz TENS session, a 110 Hz TENS session, and a control (off-TENS) session. Each session consisted of a 20- minute stimulation period and a 10-minute follow up period.
Other Name: TENS

Detailed Description:

15 healthy subjects (8 females, 7 males) with a mean age of 22.6 ± 3.7 years participated in this study.

All subjects participated, randomly, in a 4 Hz TENS session, a 110 Hz TENS session, and a control (off-TENS) session. Each session consisted of a 20- minute stimulation period and a 10-minute follow up period.

Outcome measures: Sympathetic skin response from the simulated (Right) hand and skin temperature of both stimulated (Right) and none stimulated (Left) hand was measured 15 seconds before, just 15 seconds after, and 10 minutes after application of interventions.
