Neck muscle vibration and prism adaptation fail to improve balance disturbances after stroke: A multicentre randomised controlled study.

Background: Pilot studies suggest potential effects of neck muscle vibration (NMV) and prism adaptation (PA) on postural balance disturbances related to spatial cognition.

Objectives: To evaluate the effect of 10 sessions of NMV and/or PA on ML deviation. We used the mediolateral centre of pressure position (ML deviation) as a biomarker for spatial cognition perturbation, hypothesising that PA and NMV would improve ML deviation, with a potential synergistic impact when used together.

Ten-year survival of second kidney transplants: impact of immunologic factors and renal function at 12 months.

Background: The aim of the present study was to assess long-term survival of cadaveric second kidney allografts performed in our center and to determine risk factors predictive of long-term graft outcome.

Methods: Of 1704 kidney transplantations performed between January 1985 and March 1998, 233 were second grafts. The majority of the recipients were sensitized.
