The nerves affected by Robb's spinal cord injury control both the movement and sensation in his feet. And what they tell his feet to do (or not) and feel (or not) can be pretty odd, indeed.
It has been very hot here, the last few days. We've all been looking for ways to keep cool. Robb slept -- for the first time since his accident -- without socks on. Typically, the sensation of the sheets sliding over his feet is just unbearable because of the jumbled up messages that his nerves are sending to his brain. But it was just too hot to cover his feet with socks.
And how did Robb's feet feel? Like they were on fire.
A few days back, he slipped on my flip-flops, which he had worn once or twice before. A said that he lasted all of ten seconds in them before his feet, legs and butt seized up into a mass of spasticity.
Apparently, the act of gripping onto the shoes with his toes, which most of us take for granted, was to "active" for Robb. These are the sorts of observations that leave us scratching our heads. The human body certainly is an odd and wonderful thing.
