Buttock pain is the most common pain referral area from a symptomatic hip joint. Traditionally accepted groin and thigh referral areas were less common. Hip joint pain can occasionally refer distally to the foot. Lower lumbar spine referral did not occur.

Objective: The purpose of this study was to address two underreported issues in undergraduate physical medicine and rehabilitation medical education: quantity and quality of physical medicine and rehabilitation clerkships in US medical schools. Design: A multimethod sequential design was used to evaluate the curricula of US medical schools. Quantity (N = 154) of physical medicine and rehabilitation clerkships was assessed by counting the number of required, selective, and elective clerkships in each medical school. Quality (n = 13) was assessed by conducting a thematic analysis on physical medicine and rehabilitation clerkship curricula to identify learning objectives. These objectives were then compared with learning objectives in a model standard. Results: Whereas few medical schools required a physical medicine and rehabilitation clerkship, most offered elective rotations in physical medicine and rehabilitation. Most medical schools only included 6 of the 12 model standard learning objectives. Medical schools also included 29 learning objectives not present in the model standard. Conclusions: Physical medicine and rehabilitation clerkships are not underrepresented but are underemphasized, in undergraduate medical schools. Furthermore, these clerkships use inconsistent learning objectives. Thus, findings suggest the need to draw attention to physical medicine and rehabilitation clerkships by offering them as selectives and to develop a list of standardized learning objectives. This exploratory study developed such a groundbreaking list and invites the physical medicine and rehabilitation community to test it.

BACKGROUND: The rising use of injections to treat low back pain (LBP) has led to efforts to improve selection. Nonorganic (Waddell) signs have been shown to portend treatment failure for surgery and other therapies but have not been studied for minimally invasive interventions. METHODS: We prospectively evaluated the association between Waddell signs and treatment outcome in 3 cohorts: epidural steroid injections (ESI) for leg pain and sacroiliac joint (SIJ) injections and facet interventions for LBP. Categories of Waddell signs included nonanatomic tenderness, pain during sham stimulation, discrepancy in physical examination, overreaction, and regional disturbances divulging from neuroanatomy. The primary outcome was change in patient-reported “average” numerical rating scale for pain intensity (average NRS-PI), modeled as a function of the number of Waddell signs using simple linear regression. Secondary outcomes included a binary indicator of treatment response. We conducted secondary and sensitivity analyses to account for potential confounders. RESULTS: We enrolled 318 patients: 152 in the ESI cohort, 102 in the facet cohort, and 64 in the SIJ cohort, having sufficient data for primary analysis on 308 patients. Among these, 62% (n = 192) had no Waddell signs, 18% (n = 54) had 1 sign, 11% (n = 33) had 2, 5% (n = 16) had 3, 2% (n = 7) had 4, and about 2% (n = 6) had all 5 signs. The mean change in average NRS-PI in each of these 6 groups was −1.6 ± 2.6, −1.1 ± 2.7, −1.5 ± 2.5, −1.6 ± 2.6, −1 ± 1.5, and 0.7 ± 2.1, respectively, and their corresponding treatment failure rates were 54% (102 of 192), 67% (36 of 54), 70% (23 of 33), 75% (12 of 16), 71% (5 of 7), and 83% (5 of 6). In the primary analysis, an increasing number of Waddell signs were not associated with a significant decrease in average NRS-PI (coefficient [Coef] = 0.19; 95% confidence interval [CI], –0.43 to 0.05; P = .12). A higher number of Waddell signs were associated with treatment failure, with a 1.35 increased odds of treatment failure per cumulative number of signs (P = .008). CONCLUSIONS: Whereas this study found no consistent relationship between Waddell signs and decreased mean pain scores, a significant relationship between the number of Waddell signs and treatment failure was observed.

Injury to the A2 pulley is caused by high eccentric forces on the flexor‐tendon–pulley system. Accurate diagnosis is necessary to identify the most appropriate treatment options. This review summarizes the literature with respect to using ultrasound (US) to diagnose A2 pulley injuries, compares ultrasound to magnetic resonance imaging and computed tomography, and identifies current knowledge gaps. The results suggest that US should be used as the primary imaging modality given high accuracy, relatively low cost, ease of access, and dynamic imaging capabilities. Manual resistance is beneficial to accentuate bowstringing, but further research is needed to determine best positioning for evaluation.
