Yes, many people with arthrogryposis can work. What kind of work they can do depends on the person, their mobility, hand function, strength, pain level, fatigue, and what accommodations are available. Many can do work in areas like office jobs, teaching, writing, speaking, customer service, creative work, business, advocacy, and tech. I would not say every person can work in every field, because very physical jobs or jobs that require heavy lifting, climbing, fast repetitive movement, or full body strength may not be realistic for some. As for what percentage work, I would not want to guess, because it varies too much from person to person.
