Standing-up aid

This lady had muscle weakness in her legs and having had bilateral hip replacements had limited movement, limiting her social life as she cannot rise from a chair without assistance.

It was found that the weight on the seat reduced from 50 to 10kg from sitting properly on a seat to leaning forward and trying to rise. A lightweight, portable sit-to-stamd aid in the form of a padded cushion as made with four torsion springs fitted under the plywood base which gave a ‘push’ of approximately 12kg. This ‘ejection’ assistance was enough to enable the lady to stand without outside assistance.

The lady’s social life benefited as she could stand by herself when visiting places outside her home – where she had proprietary standing assistance units. However it was not effective on soft cinema seats.
