Brief Summary:
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 or disease Intervention/treatment
Effects of TENS on Sympathetic Skin Response Device: transcutaneous electrical nerve stimulation

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.

Other Name: TENS



Primary Outcome Measures :
  1. Changes of sympathetic skin response [ Time Frame: 15 seconds before, just 15 seconds after, and 10 minutes after application of interventions ]
    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 :
  1. Changes of skin temperature [ Time Frame: 15 seconds before, just 15 seconds after, and 10 minutes after application of interventions ]
    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
