Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 35 years (Adult)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sum of Pain Intensity Difference Between 0 to 24 Hours (SPID0-24) for Study Leg While Standing
Time Frame: Baseline to 24 Hours
  • Pain Intensity (PI) was assessed for study leg while standing using a patient rated 0-100 point scale where 0 = 'no Pain' and 100 = 'worst possible pain. Pain Intensity Differences (PID) was the difference between PI at time (i) minus PI at time (t+1). The Sum of Pain Intensity Difference (SPID) was calculated as a time-weighted Sum of PID scores over a number of hours.
  • Sum of pain intensity differences over 24 hours after initiating treatment (SPID24). SPID24 derived from pain scores assessed over 24 hours on a 0 -100 point scale. SPID24 was computed using the trapezoidal rule, i.e. Σ [T(i+1) - T(i)] x [((PID)(i+1) + PID(i))/2] in an obvious notation, where T(i) is nominal time and PID(i), the pain intensity difference at Time (i).
  • Negative differences correspond to an improvement of pain, while positive differences correspond to recrudescence of pain. A higher negative value of SPID indicates greater pain relief.
Baseline to 24 Hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
