We report the presence of rebound nystagmus in seven of eight patients with DM2 in the absence of a structural brainstem or cerebellar lesion. The rebound nystagmus observed in these patients is very suggestive of ocular myotonia, and examination of patients using video-Frenzel goggles may be a useful method for diagnosing myotonia of the extraocular muscles.

We aimed to study the involvement of the SCM and to evaluate the role of the diaphragm and SCM on respiratory tests performed in ALS patients. We studied 45 patients (mean age SD: 60.6 13 years). In all patients we evaluated: neck flexion strength; forced vital capacity (FVC); maximal inspiratory pressure (PImax); sniff nasal..http://dx.doi.org/10.1002%2Fmus.21109 Complications of needle electromyography: Hematoma risk and correlation with anticoagulation and antiplatelet therapy- September 10, 2008 Electromyography (EMG) is considered a relatively safe procedure based primarily on clinical experience. Literature review reveals few reported complications from bleeding or hematoma formation. No evidence-based guidelines exist for EMG procedures in patients who are taking anticoagulant or antiplatelet medications. The purpose of this study was to determine if patients taking anticoagulant or antiplatelet agents exhibit an increased risk of hematoma formation after routine needle EMG of the...http://dx.doi.org/10.1002%2Fmus.21111 Decreased muscle atrophy F-box (MAFbx) expression in regenerating muscle after muscle-damaging exercise- September 10, 2008 A muscle-specific ubiquitin ligase, Muscle Atrophy F-box (MAFbx), is known to mediate the degradation of muscle-specific transcription factor MyoD in vitro. Its regulation in regenerating skeletal muscle, however, has not been clarified. We looked for evidence of MAFbx downregulation in the course of regeneration after muscle damaging exercise. The soleus and gastrocnemius muscles of mice were subjected to forced eccentric contraction by electrical stimulation to induce muscle damage.

We hypothesized that a ratio between the nerve cross-sectional area at the site of maximal enlargement and at an unaffected site may improve diagnostic accuracy in ulnar neuropathy at the elbow (UNE), when compared to a single measurement at the site of maximal enlargement. Ultrasound was used to measure the cross-sectional area of the ulnar nerve at three sites in 30 normal, healthy controls and 26...http://dx.doi.org/10.1002%2Fmus.21094 |
