Randomized Controlled Trial Clinical TrialLidocaine injection versus dry needling to myofascial trigger point. The importance of the local twitch response.
This study was designed to investigate the effects of injection with a local anesthetic agent or dry needling into a myofascial trigger point (TrP) of the upper trapezius muscle in 58 patients. Trigger point injections with 0.5% lidocaine were given to 26 patients (Group I), and dry needling was performed on TrPs in 15 patients (Group II). Local twitch responses (LTRs) were elicited during multiple needle insertions in both Groups I and II. ⋯ Patients treated with dry needling had postinjection soreness of significantly greater intensity and longer duration than those treated with lidocaine injection. The author concludes that it is essential to elicit LTRs during injection to obtain an immediately desirable effect. TrP injection with 0.5% lidocaine is recommended, because it reduces the intensity and duration of postinjection soreness compared with that produced by dry needling.

Methods used in the evaluation of clinical competency of physical medicine and rehabilitation residents.
A 17-item questionnaire was designed to determine how physical medicine and rehabilitation (PM&R) training directors assess their residents' clinical competency. A response rate of 83% (62/75) was obtained. Seventy-nine percent (49/62) have a written resident supervision policy, and 73% (45/62) have a written resident probation policy. ⋯ Forty-seven percent (29/62) of the programs have asked at least one resident to leave their program in the past 3 yr. The OSCE is emerging as the state-of-the-art method for assessing clinical skills, although it is expensive. The measurement of clinical competency is important in the certification and recertification process, and our specialty needs better methods to assess these performance skills.
