Encephalitis herpes simplex: aural rehabilitation following bilateral deafness.
Aural rehabilitation is a critical and often neglected aspect of a hearing-impaired patient's total rehabilitation. This case description illustrates the need for implementation of aural rehabilitation services. A 59-year-old woman exhibited bilateral profound sensorineural hearing loss following the onset of encephalitis herpes simplex. Auditory amplification attempts were unsuccessful. Aural rehabilitation was initiated immediately, and she was seen for lipreading and vibrotactile stimulation training. Goals progressed from identification of single words within a category to phonemic recognition. Vibrotactile stimulation was used to facilitate environmental awareness. Therapy goals reflected the patient's increased motivation to communicate within her environment. This patient's communicative status is viewed on a continuum: from success in individual treatment goals, extending to successful communication within the structure of the entire rehabilitation setting, and finally to functional communication within her home environment.

Tendon reflex latencies in the upper extremity.
This study was aimed at establishing a baseline for the latency values of the biceps-brachii, triceps-brachii and brachioradialis tendon reflexes from the moment of elicitation by percussion of the tendon, to the appearance of the muscle action potential. The percussion hammer triggered the electronic sweep on the electromyograph oscilloscope, showing latency to the onset of the potential. Standard skin electrodes were used. Certain precautions were taken to avoid artifacts caused by skin movement. Thirty normal volunteer subjects, between the ages of 17 and 55 years, were examined. Biceps reflex latency values varied between 9 and 14 msec; with a mode of 11 msec and an average of 11 msec. Triceps latency values varied between 9 and 13 msec; with a mode of 11 msec and an average of 10 msec, and brachioradialis latency values varied between 13 and 20 msec, with a mode of 16 msec and an average of 16 msec.
