What is Arthrogryposis?

What is Arthrogryposis?


Arthrogryposis, also called Arthrogryposis Multiplex Congenita (AMC), is an umbrella term that describes several conditions that cause increased stiffness in the muscles and joints. It is a rare condition impacting 1 in 3000 births. In Greek, “Arthro” is the term for joints and “gryposis” is the term for curving, so it literally translates to “curved joints.” A child who is born with Arthrogryposis will have contractures (shortening of tendons or muscles) that affect more than one joint. The joints most commonly impacted include: shoulders, knees, elbows, ankles, fingers, wrists, toes, hips, jaw.


How is Arthrogryposis diagnosed?


Arthrogryposis can be diagnosed as early as in utero using ultrasound, amniocentesis, or chorionic villus samplings or is diagnosed at birth. Genetic testing is typically performed to determine if there is an underlying cause for the development of Arthrogryposis. However, the cause is often unknown. Risk factors include: decreased amniotic fluid, abnormally shaped uterus, multiple fetuses, spina bifida, muscular dystrophy,
myasthenia gravis, dwarfism, maternal diagnosis of multiple sclerosis, etc.


How does Arthrogryposis impact function?


Individuals with Arthrogryposis tend to see multiple specialists to manage their contractures. They are closely followed by orthopedists, orthotists, physical medicine, and physical and occupational therapists. They typically go through multiple rounds of surgery and casting to improve the mobility in their joints and frequently use bracing to help maintain their mobility and provide support to their joints. As the presentation of Arthrogryposis varies greatly from person to person, so does their function. Some individuals use a wheelchair to access their environment, some use assistive devices such as walkers or crutches, and some are able to walk independently.


Arthrogryposis is not a progressive disorder and only impacts the muscles. It does not impact an individual’s cognitive processes, learning capabilities, or life expectancy and many people with Arthrogryposis go on to live long and fulfilling lives. 


Why we love our friends with Arthrogryposis!


Here at PMC, we love working with our clients with Arthrogryposis because they are so inspiring. They never give up, even when things are challenging for them and they are always thinking of new and creative ways to move their bodies. They don’t let their limitations in mobility hold them back from achieving their dreams. We could all learn a thing or two from them about how impactful perseverance, hard work, and a positive attitude can be on changing the way you view a challenging situation.

At Pediatric Movement Center, we believe that movement isn’t just about gross motor development—it’s intertwined with confidence, self-esteem, and real-life functional skills. That’s why helping children gain independence in self-care tasks (dressing, grooming, feeding, toileting) is such an essential piece of the puzzle. Empowering your child to participate in self-care doesn’t just free up time for caregivers. It helps children build motor planning, coordination, problem solving, and a sense of accomplishment. Why Self-Care Skills Matter 1. Motor & cognitive integration Tasks like buttoning, tying shoelaces, brushing hair, and managing zippers demand fine motor control, bilateral coordination, sequencing, and problem solving. 2. Boosting confidence and motivation When children are capable of doing things for themselves (even partially), they feel more competent and proud. 3. Reducing caregiver burden As your child becomes more independent, your role gradually shifts toward coaching rather than doing. 4. Supporting transition to school / life Teachers, peers, and daily routines expect kids to manage many of their own care tasks. Early development of these skills smooths transitions. Common Challenges You May See By recognizing common challenges, you are better prepared to break down tasks and scaffold progress more effectively. 1. Dressing (buttons, zippers, socks) Weak finger dexterity, poor grip strength, sequencing difficulties Frustration, avoidance, slow performance 2. Grooming (hair brushing, face washing) Sensory sensitivity, poor bilateral coordination Child resists touching face, hair, water on face 3. Feeding / Utensil use Hand dominance not established, weak wrist stability Spilling, awkward grasp, switching hands 4. Toileting / Hygiene Motor planning, reach, coordination Difficulty wiping, managing clothing, following steps independently Tips & Strategies to Support Self-Care Growth Here are some practical strategies and tips to help your child grow their self-care skills with joy and confidence. 1. Break Tasks Into Smaller Steps For example, rather than asking your child to “get dressed,” break that down: Pull pants up > Hold waistband > Insert one foot > Insert the other foot > Pull up > Zip / snap / button Tip! Label each step with visuals or checkboxes so your child can see the progression. 2. Use Adaptive Tools & Clothing Modifications let your child practice success while their skills build! Choose clothes with large, easy-to-grasp fasteners (e.g. big buttons, magnetic snaps, Velcro). Use looped zipper pulls or zipper tabs to simplify grip. Utensils with thicker grips or angled handles can ease feeding. 3. Practice in Playful, Low-Pressure Ways Turn grooming into a “spa day” — let your child brush a doll’s hair first, then their own. Sing a song while they dress themselves, doing each step in time. Use a mirror so they can see what they are doing and become more aware of hand movements. 4. Encourage Bilateral Coordination & Strength Games and activities that involve both hands—stringing beads, cutting construction paper, playdough work—help build the coordination needed for self-care. 5. Use Visual Schedules & Reminders A picture-based routine board (e.g. “wash face → brush teeth → comb hair → get dressed → go to school”) offers structure and helps children internalize the sequence. Having the steps visible reduces reliance on verbal prompts. 6. Encourage Autonomy (While Supporting) Let your child try, with you ready to assist only when needed. Use open choices (e.g. “Do you want to put on your socks first or shoes first?”) to promote decision-making. Praise attempts, not just successes: “I saw how you tried to button that shirt — great persistence!” 7. Be Patient & Repeat Often Mastering self-care takes time and repetition. Try to incorporate these tasks multiple times a day. Over months, small progress accumulates into real independence. 8. Address Sensory or Motor Barriers If a child resists face washing, brushing teeth, or hair care, sensory sensitivities may be involved. Gentle exposure, gradual desensitization, and input from occupational therapy can ease the process. When to Seek Support from a Therapist If you notice consistent challenges with a task despite practice, our therapy team is ready to evaluate fine motor, coordination, sensory processing, or motor planning components. You might want to consider occupational therapy support if: Your child is older than peers for their age and still not handling basic self-care tasks They become frustrated, shut down, or avoid attempting these tasks You suspect underlying issues like poor fine motor control, motor planning difficulties (dyspraxia), or sensory sensitivities The gap between what the child can do and what’s expected in school life is widening Therapists can perform assessments, design individualized strategies, and coach you (the parent/caregiver) on how to guide progress at home. At Pediatric Movement Center, we’re honored to partner with families on this journey. If you’d like help assessing which areas to focus on, designing a routine, or troubleshooting stalls in progress, reach out. We’d love to support your child’s growth and celebrate every milestone with you Helping your child with self-care skills is not just about independence—it fosters motor development, confidence, and daily life readiness. With patience, scaffolding, and playful opportunities, you’ll watch them grow step by step into more self-reliance.
