I see no reason why people with TM cannot work, once the initial phase has settled and the person is feeling well.
Many jobs can be adapted to accommodate a wheelchair, however a diagnosis of TM does not mean wheelchair use. Most sufferers recover their mobility to some degree, and most can drive a car, even if adapted.
Unfortunately, I had to give up my job as a district nurse, and perhaps jobs such as this which involve driving and then physical work with less able members of the public should not be considered, as it may put the person and the patient at risk, although I would now be able to carry out any aspects of the job.
