ReviewIntroduction to diagnostic musculoskeletal ultrasound: part 2: examination of the lower limb.
This is the second of two articles focusing on ultrasound examination of musculoskeletal components of the upper and lower limbs. Treatment of musculoskeletal injuries is based on establishing an accurate diagnosis. ⋯ This article describes the ultrasound examination of the lower limb in terms of anatomic structure. Normal and pathologic ultrasound features of these structures, including muscles, tendons, ligaments, bursae, and other soft tissues of the lower limb, will be described by reviewing several representative pathologies commonly seen in musculoskeletal medicine.

Association between the EMG self-assessment examination and later ABEM certification.
Our objective was to determine whether performance on the American Association of Neuromuscular and Electrodiagnostic Medicine Training Program Self-Assessment Examination (TPSAE) predicts subsequent performance on the American Board of Electrodiagnostic Medicine (ABEM) certification examination. The TPSAE results were closely associated (r = 0.57) with ranking on the ABEM examination. Those with scores <65% on the TPSAE had <50% chance of ABEM certification, whereas those with scores >84% correct had >90% chance of certification. The TPSAE is a useful predictor of later ABEM certification.

Association of cross-sectional area of the rectus capitis posterior minor muscle with active trigger points in chronic tension-type headache: a pilot study.
To investigate whether cross-sectional area (CSA) of the suboccipital muscles was associated with active trigger points (TrPs) in chronic tension-type headache (CTTH). ⋯ It seems that muscle atrophy in the RCPmin, but not in the RCPmaj, was associated with suboccipital active TrPs in CTTH, although studies with larger sample sizes are now required. It may be that nociceptive inputs in active TrPs could lead to muscle atrophy of the involved muscles. Muscle disuse or avoidance behavior can also be involved in atrophy.
