Popeney et al evaluated the response following surgery in patients with pudendal nerve entrapment. The authors are from Fort Bend Neurology in Sugar Land, Texas.
Assessments: before surgery and 12 months after
Measures:
(1) pain (as a visual analogue scale)
(2) global overall improvement (in pain)
(3) improvement in function and quality of life
Criteria for surgical response - at least one of the following:
(1) > 50% reduction in pain
(2) > 50% improvement in global assessment
(3) > 50% improvement in function and quality of life
Limitation in using percent improvement: A person with minimal impairment may not notice much change in a parameter.
These criteria were modified in the implementation as following:
Finding
Term
all normal
complete response
all improved by > 50%
good response
one or more improved by > 50%, all improved
fair response
one or more improved
partial response
none improved
unchanged
one or more worse
progression
some improved and some worse
mixed response
