Quantitative testing of a patient’s basal pain perception before surgery has the potential to be of clinical value if it can accurately predict the magnitude of pain and requirement of analgesics after surgery. Continue reading “Preoperative Prediction of Severe Postoperative Pain”
WHO treatment guides for cancer pain provide explanations of the pathophysiology of such pain, how to make adequate assessments, how to choose analgesics, and how to use the ladder. Early studies on its effectiveness demonstrated that the method proposed by the WHO offered inexpensive treatment and adequate relief for 70% to 90% of cancer patients with pain. Continue reading “WHO Analgesic Ladder for Pain Management”
The numeric rating scale (NRS) is a single 11-point numeric scale broadly validated across myriad patient types. Data obtained via NRS are easily documented, intuitively interpretable, and meet regulatory requirements for pain assessment and documentation. Continue reading “Numeric Pain Rating Scale”
The Oswestry Disability Index (ODI) is an index derived from the Oswestry Low Back Pain Questionnaire used by clinicians and researchers to quantify disability for low back pain. Zero is equated with no disability and 100 is the maximum disability possible. Continue reading “The Oswestry Disability Index (ODI) Version 2.1a or Oswestry Low Back Pain Disability Questionnaire”
Complex regional pain syndrome (CRPS) has been known by many names, but most commonly as reflex sympathetic dystrophy and causalgia (as attributed to Evans and Mitchell, respectively). In the past, it was diagnosed using a variety of nonstandardized and idiosyncratic diagnostic systems. The name was ultimately changed to complex regional pain syndrome (CRPS) at a consensus workshop in Orlando, Florida, in 1994, with the new name and diagnostic criteria codified by the International Association for the Study of Pain (IASP) task force on taxonomy.
