Median and ulnar nerve conduction studies among workers: normative values.
To determine normative values for nerve conduction studies among workers, we selected a subset of 326 workers from 955 subjects who participated in medical surveys in the workplace. The reference cohort was composed exclusively of active workers, in contrast to the typical convenience samples. Nerve conduction measures included bilateral median and ulnar sensory amplitude and latency (onset and...
متن کاملComparison of magnetic and electrical phrenic nerve stimulation in assessment of phrenic nerve conduction time.
Cervical magnetic stimulation (CMS), a nonvolitional test of diaphragm function, is an easy means for measuring the latency of the diaphragm motor response to phrenic nerve stimulation, namely, phrenic nerve conduction time (PNCT). In this application, CMS has some practical advantages over electrical stimulation of the phrenic nerve in the neck (ES). Although normal ES-PNCTs have been consiste...
متن کاملMedian Nerve Conduction in Healthy Nigerians: Normative Data
BACKGROUND Because of lack of local normative data, electrodiagnostic laboratories in Nigeria apply standard values generated in the USA and Europe to diagnose different median nerve abnormalities. AIM To develop normative values for motor and sensory median nerve conduction studies (NCSs) in Nigerian population. SUBJECTS AND METHODS In a cross-sectional study design, a total of 200 healthy...
متن کاملNormative data of upper limb nerve conduction in Central India.
Nerve conduction study is an important tool to evaluate peripheral nerve abnormality. The primary purpose of this study was to provide normative electrophysiological data for commonly tested upper limb nerves in normal healthy adults. Nerve conduction studies were performed prospectively in upper limbs of 175 carefully screened healthy volunteers between the ages of 18 and 66 years using standa...
متن کاملA normative study of nerve conduction
The temporal branch of the facial nerve is particularly vulnerable to traumatic injuries during surgical procedures. It may also be affected in clinical conditions. Electrodiagnostic studies may add additional information about the type and severity of injuries, thus allowing prognostic inferences. The objective of the present study was to develop and standardize an electrophysiological techniq...
