Living with an autoimmune disease like ankylosing spondylitis has meant living with chronic pain and impaired mobility, but I was surprised, yea alarmed when the muscles in my hand and forearm started to uncontrollably spasm and twist into a claw-like flex. Dark thoughts of tetanus came to mind and at one less-than-lucid moment I wondered if I’d become mind-controlled by the Skeksis from Dark Crystal but good sense returned and I began to research for a solution to my manual woes. It turns out that the flexing and arching and “owwing” is a real thing – it’s known as a carpal spasm and can be brought on by overwork and/or the lack of sufficient calcium or magnesium in my diet. By limiting my time at the drawing board and knocking back an extra yogurt each day I’ve been able to curtail the attacks to a large extent.
…which is just as well.
Since my childhood there has been a dramatic increase in the use of hand gestures as part of human communication far beyond the sign language between cowboy and Commanche that I witnessed each week on television. Simple movements such as an index finger drawn sharply across a larynx (“killed”) or a hand cupped to an ear (“listening”) have been joined by American Sign Language for use by the deaf, gang signs adopted into general street use, and other communicative gestures borrowed from sports and military. The use of nonverbal communication has increased to the point that it is no longer safe to just idly wave your hands. For example while coming to grips with these carpal spasms I have:
- Been slapped by a deaf lady for signing an indecent proposal
- Accidentally called out a gang member
- …and I may have inadvertently flipped off ET
The one time I did try to respond to communicating via hand signals it turned out that the lady in question was just trying to dry her nail polish…which is why despite years of conditioning via the military I now walk about with my hands in my pockets.
