Abstract

Increased interest and use of urodynamic testing have led many clinicians to rely on the results for patient care. Numerous shortcomings and possible sources of error have been identified. Well trained personnel, properly structured examination rooms and understanding of the potential pitfalls in urodynamics are essential to proper medical management of patients with micturition problems.

Modulation operated by the sympathetic nervous system on jaw reflexes and masticatory movement.

The sympathetic nervous system (SNS), that is activated under condition of physical, psychological and psychosocial stress, affects force production and fatigability of muscles by controlling both muscle blood flow and the intracellular contractile mechanism. In addition SNS may affect motor function by modulating afferent activity from muscle spindles that are highly concentrated in jaw-closing muscles. Possible implications of these actions on masticatory function and myofascial pain are discussed.

Abnormal responses to repetitive transcranial magnetic stimulation in multiple system atrophy.

We studied the response of the motor cortex to brief trains of suprathreshold repetitive transcranial magnetic stimulations (rTMS) in patients with the Parkinson-variant of multiple system atrophy (MSA-P) and compared it to patients with idiopathic Parkinson's disease (PD) and healthy controls. Eight subjects were studied in each group, and patients were matched for disease severity as assessed by Hoehn & Yahr stages. rTMS was delivered at rest and during low-level contractions in trains of 10 stimulations at 5 Hz, and stimulation intensity was set to result in an motor evoked potential (MEP) in the first dorsal interosseus muscle of 0.5 to 1.0 mV. In MSA-P, MEP amplitude at rest was already reduced after the second stimulus and remained so, while it did not change in PD and controls. During contraction, MEP size did not change during the train in any group. The silent period that followed the last stimulus was of similar duration as the first stimulus in MSA-P, but was increased in PD and controls. These findings indicate that abnormal inhibition occurs within the motor cortex in MSA-P, despite dopaminergic treatment and indicate differences in cortical dysfunction between MSA-P and PD. We suggest that these abnormalities reflect the motor cortex pathology found in MSA-P.
