Brief Summary:
This study was conducted to explore the influencing factors, subjects and testers' evaluation about pain measurement with hand-held pressure algometer with different size probes. Methods:100 healthy undergraduate students(50 males and 50 females) were recruited into this study. Pain measurement including pressure pain threshold (PPT) and pressure pain tolerance(PTO) was carried out by the hand-held pressure algometer with different size probes (from 1cm2 to 0.01cm2) on three different measuring spots in right forearm. We recorded subjects' skinfold thickness, time per test procedure, types of pain perception, receptivity and degree of accuracy as well as testers' level of laborious.

Detailed Description:
Subjects with the following diseases were excluded: known history of chronic disease, psychiatric diseases or communication disorders, diabetes mellitus, severe cardiovascular diseases, kidney or liver diseases with poor hepatic function, alcohol or drug abuse, heavy smoker, Pregnancy or at lactation period .

Primary Outcome Measures :
  1. Pressure Pain Threshold (PPT)With 1 cm2 Probe [ Time Frame: 1 hour after the procedure ]
    The value was calculated as a avarage value of different measurement sites

  2. Pressure Pain Tolerance (PTO) With 1cm2 Probe [ Time Frame: 1 hour after the procedure ]
    The value was calculated as a avarage value of different measurement sites

  3. Pressure Pain Threshold (PPT)With 0.1 cm2 Probe [ Time Frame: 1 hour after the procedure ]
    The value was calculated as a avarage value of different measurement sites

  4. Pressure Pain Threshold (PPT)With 0.01 cm2 Probe [ Time Frame: 1 hour after the procedure ]
    The value was calculated as a avarage value of different measurement sites

  5. Pressure Pain Tolerance (PTO) With 0.1cm2 Probe [ Time Frame: 1 hour after the procedure ]
    The value was calculated as a avarage value of different measurement sites

  6. Pressure Pain Tolerance (PTO) With 0.01cm2 Probe [ Time Frame: 1 hour after the procedure ]
    The value was calculated as a avarage value of different measurement sites


Secondary Outcome Measures :
  1. Time of Each Test Procedure [ Time Frame: 10 minutes after the procedure ]
  2. Measuring Values of Skinfold Thickness [ Time Frame: 10 minutes after the procedure ]
