Surface EMG and MFCV during attacks of HOPP 85 SURFACE EMG AND MUSCLE FIBER CONDUCTION DURING ATTACKS OF HYPOKALAEMIC PERIODIC PARALYSIS
نویسندگان
چکیده
Surface EMG, muscle fiber conduction velocity (MFCV), muscle force and biochemical variables were investigated in a 13-year-old boy with familial hypokalaemic periodic paralysis (HOPP) during and after three attacks of paralysis. After normalisation of the serum potassium values, strength rapidly returned to interictal values, but the integrated EMG and to a lesser extent the MFCV recovered more slowly. These findings suggest that a complete electrophysiological recovery is not necessary for a restoration of muscle force and that the pathogenetic defect is localised in the muscle membrane.

متن کاملImprovement of muscle strength in familial hypokalaemic periodic paralysis with acetazolamide.
A double blind cross-over study of eight patients with familial hypokalaemic periodic paralysis was made to assess the influence of acetazolamide on muscle strength. All patients had a reduced interictal muscle fibre conduction velocity. Five patients had no attacks at the time of the study. One patient withdrew from the study because of an adverse reaction. The muscle strength of 11 muscle gro...

We studied muscle fatigue and recovery on healthy males by means of surface and invasive EMG, on biceps brachii and brachioradialis muscle. Fatigue was induced by 1 min of maximal voluntary contraction (MVC), recovery was studied during 60 min (surface EMG) and 15 min (invasive EMG). The main finding was a long-lasting 'supernormal' muscle fiber conduction velocity (MFCV) during recovery. After...

Muscle fiber conduction velocity (MFCV) is studied in 51 healthy volunteers using an invasive (IMFCV) and a surface (S-MFCV) EMG technique in the biceps brachii, in order to acquire normal values and to study reproducibility and effects of gender and age. In the invasive technique, muscle fibers are directly stimulated with needle electrodes, and the latencies of the evoked potentials are measu...
