The Hoffmann (H) reflex was measured from a grid of 31 locations on the calves of 20 healthy volunteers. In 17 cases the maximum amplitude of response was found at a site more distal than at the conventional midcalf recording location. Three quarters of the distance between the popliteal crease and the flare of the medial malleolus, the waveform was found… (More)
Intramuscular (IM) recordings are often used in nerve conduction studies involving deep or proximal muscles and in other electrodiagnostic tests. Little is known of how various needle electrode configurations and placements influence the characteristics of the evoked responses and their clinical interpretation. The present set of investigations sought to… (More)
Abnormal spontaneous activity is a hallmark of acute or subacute denervation of skeletal muscle, particularly in patients with uremic neuropathy. We report 5 patients in whom such activity was unexpectedly minimal or absent.
This study was designed to elucidate the role of different muscles of the posterior compartment of the lower leg in the generation of the surface-recorded H-reflex. H-reflexes were evoked through percutaneous stimulation of the posterior tibial nerve and recorded concurrently, using monopolar electrodes from the soleus (SOL), medial and lateral gastrocnemii… (More)
Medical management of the agitation associated with acquired brain injury (ABI) has been proble matic. At least 12 distinct drugs are currently recommended in the medical literature. In recent years, on the ABI in-patient rehabilitation unit, methotrimeprazine (MTZ) has come to be the preferred drug and is used routinely for effective treatment of… (More)
Eighty persons with first-time, nontraumatic amputation, mean age 66.7 yrs +/- 12.6 (1 SD) were examined to determine the extent of peripheral neuropathy (PN) present in the intact limb. Thirty-eight (47.5%) of the subjects had confirmed diabetes mellitus (DM); in those subjects, vibration sense (73.3%), temperature sense (42.1%), and nociception (71.1%)… (More)
