[The value of kinematic data on the lumbosacral spine in differentiating between 4 levels of classification of the lumbosacral syndrome].

Dynamic capacity of the spine was measured on the basis of electrokinesiological findings (EK) with the purpose of finding out how the clinical classification factors of the lumbosacral spine (LS) affect the kinematic indicators. The EK scan contains quantified kinematic and myoelectrical data on the LS spine recorded during motion of the body in the sagittal plane. A total number of 110 patients with low back pain and/or ischialgia of degenerative etiology were examined and compared with 42 healthy controls.

The H or F wave latencies in medial gastrocnemius in the electrodiagnostic study of sciatica patients with suspected S1 radiculopathy.

The aim of this study was to test H or F wave latencies of medial head of gastrocnemius muscle for electrodiagnostic evaluation of patients with suspected S1 radiculopathy with or without additional L5 radiculopathy. A group of 97 patients (34 female and 63 male), aged 20-60 (average 44 years), with clinically suspected unilateral radiculopathy were studied. Needle EMG of medial gastrocnemius muscle was supplemented by H or F wave latencies measurement bilaterally by percutaneous stimulation of tibial nerve in cubital fossa.
