Multicenter Study Observational Study
Prevalence and Time Course of Post-Stroke Pain: A Multicenter Prospective Hospital-Based Study.
Pain prevalence data for patients at various stages after stroke. ⋯ Pain after stroke is more frequent in the subacute and chronic phase than in the acute phase, but it is still largely undertreated.

Multicenter Study Controlled Clinical Trial
The Effects of Local Anesthesia Administration on Pain Experience During Interventional Spine Procedures: A Prospective Controlled Trial.
It has been postulated that local anesthetic administration may be the most painful part of interventional spine procedures. Despite this, there is a lack of evidence supporting the commonly used traditional technique of anesthetic delivery as part of these procedures. This study tested three hypotheses: 1) alternative method of local anesthesia injection is superior to the traditional method; 2) using the traditional method of injection is not superior to using no local anesthetic; and 3) treatment needle size, anesthetic injection technique, and sedation are associated with pain experienced during procedures. ⋯ The alternative method was superior (P < 0.05) to the traditional method on post procedural pain scores. Injecting local anesthetic with the traditional or alternative method was not superior to using no local anesthetic. Treatment needle size, pain at one inch of treatment needle insertion, and baseline pain were all significantly (P < 0.05) associated with overall procedural pain. Further studies are needed optimize and justify local anesthetic injections for these procedures.

Adverse Event Rates Associated with Transforaminal and Interlaminar Epidural Steroid Injections: A Multi-Institutional Study.
Transforaminal epidural steroid injections (TFESI) have demonstrated efficacy and effectiveness in treatment of radicular pain. Despite little evidence of efficacy/effectiveness, interlaminar epidural steroid injections (ILESI) are advocated by some as primary therapy for radicular pain due to purported greater safety. ⋯ Both transforaminal and ILESI are safely performed with low immediate and delayed adverse event rates when informed by evidence-based procedural guidelines. By demonstrating comparable safety, this study suggests that the choice between ILESI and TFESIs can be based on documented efficacy and effectiveness and not driven by safety concerns.

Multicenter Study Clinical Trial
The Treatment of Longstanding Complex Regional Pain Syndrome with Oral Steroids.
Evaluate the effectiveness of oral steroids in relieving pain in patients with Complex Regional Pain Syndrome (CRPS) of more than 3 months duration. ⋯ This study provides indications that the efficacy of oral corticosteroids is limited in treating CRPS of more than 3 months duration who did not respond to previous treatment. Randomized controlled studies (with enriched designs), or single subject designs would be required to identify the possible existence of a patient subgroup with a specific disease profile that may benefit from a steroid treatment.

The Reliability and Validity of the Cantonese Version of the Pain Treatment Satisfaction Scale (ChPTSS) in a Sample of Chinese Patients with Chronic Pain.
The Pain Treatment Satisfaction Scale (PTSS) was developed in a Western context for evaluating patients' satisfaction with pain treatment. Although the instrument was shown to possess good psychometric properties, its reliability and validity among ethnic Chinese has not been examined. This article reports the translation of the English-language version of the PTSS into Traditional Chinese Cantonese (ChPTSS) and the preliminary examination of the reliability and concurrent predictive validity of the ChPTSS. ⋯ Our results offer preliminary evidence for the reliability and concurrent predictive validity of the ChPTSS, which can be applied in Cantonese speaking context.
