Total pain relief from 0 to 4 hours post-injection (TOTPAR4), one of two primary measures of the study, employed patient ratings of pain relief using a 0-100 millimeter Visual Analog Scale
(VAS), summed over 4 hours.
In the remaining 20 patients, the number of painful days per month decreased significantly 6 and 12 months after insertion of the IUD, as did pain scores on the visual analog scale
and the verbal report, Dr.
The mean pain score among 40 women in the randomized double-blind study who were treated with 50/50 nitrous oxide and oxygen at the time of IUD insertion was 54 mm on a 100-mm visual analog scale
, which was not significantly different from the mean of 55 mm in women who received only oxygen.
The coprimary outcomes were the proportions of patients showing at least a 30% improvement in symptoms at 20 weeks as measured by the total WOMAC (Western Ontario and McMaster Universities) osteoardritis index and a visual analog scale
for knee pain.
To evaluate back pain, Visual Analog Scale
(VAS) was used.
Global hand pain rated on a 100 mm visual analog scale
fell by 20 mm for patients taking chondroitin, as compared with 11.
All 7 RCTs compared acupuncture with sham acupuncture and measured pain intensity using the visual analog scale
Using a visual analog scale
(VAS) we assessed the patient's functional status and quality of life pre PVP, and week, 1 month, and 6 months post PVP (Table 1) (3).
Pain levels at rest, during motion and while asleep were also scored by visual analog scale
before treatment, after treatment and at one month after treatment.
Data Source: Visual analog scale
scores recorded on weekdays and weekend days by 157 patients with osteoarthritis.
Exit site erythema, edema, exudate, and general quality of wound healing were graded during monthly follow-up using a visual analog scale
[worse (0) to better (10), relative to cuffed tunnelled catheter (5)].
Air hunger intensity was rated at the end of each breath on a visual analog scale
