Emg f-wave
WebF wave latency has been shown to be a simple and valuable method in evaluation of proximal part of peripheral nerves. According to our previous study of F wave of upper extremity nerves (1), maximum normal F wave latency for the median nerve was 28 ms with stimulation at wrist and 25 ms with stimulation at elbow. WebIn radiculopathies, F wave studies were particularly useful in milder cases, when the EMG data were inconclusive. F Wave studies should include Fmin, Fc, and Fp. The judicious …

WebConclusions: The H reflex is the most sensitive test for early GBS. Upper extremity SNAPs are also frequently abnormal in early GBS. Absent H response, abnormal F wave, and abnormal upper extremity SNAP combined with a normal sural SNAP are characteristic of early GBS. If multiple nerves are tested, definite diagnosis is possible in half the ... WebPurpose: To investigate F-wave as a method to identify a specific root lesion of L5 or S1 and to quantitatively evaluate the severity and progression of motor root lesions in lumbosacral radiculopathies (LR). Methods: Both peroneal and tibial F-waves were performed bilaterally in 142 patients with unilateral L5 or S1 radiculopathies and 37 controls along with …
WebF wave latency has been shown to be a valuable method in evaluation of a variety of neurologic disorders. We measured F wave values in 50 healthy individuals in Shiraz.
