We assessed the use of a microswitch cluster to improve assisted ambulation in a man with multiple disabilities. The cluster included two optic microswitches at the man's heels to detect his steps and a pressure microswitch under his right arm to detect his body posture (i.e. whether he had an upright, appropriate posture or was leaning forward). The man received 2.5 seconds of favourite stimulation at each step provided that his posture was appropriate. The results showed that there was a large increase in the man's appropriate posture during walking throughout the intervention phases and the 3-month follow-up.
