Utility of a low-cost wireless force platform as a potential clinical test of balance recovery after neuraxial anaesthesia.
Recovery of balance after neuraxial anaesthesia can remain delayed after simple clinical tests have demonstrated motor recovery. Dynamic posturography tracks the small movements or sway of a person standing as still as possible on a force platform and has been investigated as an objective measure of the ability to walk following anaesthesia. These are expensive laboratory devices, limiting their clinical utility. One measured variable is path length, the cumulative distance travelled in the horizontal plane by the centre of pressure of a person standing on the platform over 1min. Path length might potentially be measured using the Nintendo® Wii-Fit Balance Board™. ⋯ The path lengths were in close agreement and the Wii-Fit Balance Board™ may be worthy of further investigation as a tool to objectively assess readiness to ambulate following neuraxial anaesthesia.

In obstetrics, post-dural puncture headache is a well-recognised complication. Typical symptoms include fronto-temporal or occipital headache, worsening with ambulation and improving in the decubitus position. Occasionally, patients present with non-postural headache, although relatively little is known about this atypical presentation. The purpose of this study was to determine the incidence, associated signs and risk factors for this atypical manifestation of post-dural puncture headache. ⋯ Anaesthetists should be aware of this atypical clinical presentation, particularly if there is a past history of migraine, a more cephalad level of needle insertion or identification of dural puncture by aspiration of cerebrospinal fluid from the epidural catheter.
