My dad loves cycling, however he has dystonia which reduces control of the muscles in his hands. He can still cycle, however this becomes very painful after a moderate period of time due to gripping the handlebars, and also reduces his control of the bikes movement.
An answer related to this question advises the use of a steering damper to help with stabilisation, however I was also wondering if anyone knew where I would be able to buy something like this:
My dads right arm is better than his left, and he still has control in his forearms, so if possible the device would allow him to steer using his forearms. Any help would be appreciated.
