Understanding Arthrogryposis Multiplex Congenita (AMC)

Arthrogryposis Multiplex Congenita (AMC) is a rare condition where joints are stiff at birth. It affects many parts of the body, making it hard for children to move and live their daily lives⁴.

Definition and Characteristics

AMC is a group of conditions with stiff joints in many areas. It often affects arms and legs. Children may have stiff wrists, hands, elbows, and other joints, along with weak muscles and sometimes curved spines⁵.

Prevalence and Impact

AMC is found in 1 in 3,000 to 1 in 56,000 babies worldwide. The exact number depends on where you are and how it’s counted⁴. Over 400 genes have been linked to different types of AMC, with amyoplasia being the most common⁶.

AMC Type	Prevalence	Inheritance Pattern
Amyoplasia	Most common	Sporadic
Distal Arthrogryposis	At least 10 forms	Known gene mutations
Other AMC forms	Varied	Autosomal recessive, dominant, or X-linked

Common Clinical Manifestations

AMC is known for stiff joints, which limit movement and weaken muscles. Children with AMC struggle with moving, caring for themselves, and doing everyday tasks⁴. About one-third may also have brain or spinal cord problems⁶.

It’s important to catch AMC early and start treatment quickly. This usually includes physical and occupational therapy, and sometimes surgery. Teaching families how to help their child is also key⁵.

Early Intervention and Assessment

Early intervention is key in managing Arthrogryposis Multiplex Congenita (AMC). This condition affects 1 in 3000 to 1 in 4300 live births. Timely AMC assessment is vital⁷. It can greatly improve children’s life chances, helping with physical, speech, and social skills⁸.

Initial Evaluation Process

The first step in assessing AMC is a detailed evaluation. This includes checking the child’s breathing, measuring joint movement, and assessing muscle strength. Muscle strength in upper limbs might be 3-4/5, while lower limbs could be 5/5⁹.

Developmental Milestones

Tracking developmental milestones is crucial in early AMC intervention. Physical therapists monitor progress in motor skills, speech, and thinking. Early help boosts speech and language skills, aiding in reading, writing, and talking⁸.

Multidisciplinary Team Approach

A team of experts is vital for AMC care. This team includes physiotherapists, occupational therapists, and orthopaedists. They work together to improve the child’s mobility and strength.

Physical therapy for AMC may include gentle joint manipulation and massage. Stretching exercises are recommended 3-5 times a day. Each stretch should last 20-30 seconds⁹. Other treatments might include aquatherapy, hippotherapy, and learning to use assistive devices.

Getting families involved and educating them is also important. With early intervention and a dedicated team, children with AMC can see big improvements in their lives and development.

Physical Therapy for AMC

AMC physiotherapy greatly improves life quality for those with arthrogryposis multiplex congenita (AMC). This rare condition affects 1/3000 to 1/56,000 babies. It requires detailed rehabilitation to manage joint contractures and muscle weakness⁴.

The main goal of AMC physiotherapy is to boost joint movement and strength. It focuses on three main areas: body structure, activity, and participation¹⁰. Starting treatment early is key, with plans adjusted for each child’s age.

For babies (0-18 months), therapy works to increase joint movement and fix deformities. It uses orthotics, casting, and taping to stretch muscles and joints constantly¹⁰. These methods help babies move and learn about their world.

As kids get older, therapy changes to meet their new needs. Occupational and physical therapy are key, helping joints move better. Aquatic therapy adds strength and movement exercises⁵.

Teaching families is a big part of AMC care. Therapists show how to position, stretch, and avoid harmful activities⁵. This teamwork makes care consistent and more effective.

Though therapy is central, surgery might be needed for severe cases. These surgeries aim to improve joint movement and fix spine issues⁵.

Range of Motion Techniques

Range of motion techniques are key in managing Arthrogryposis Multiplex Congenita (AMC). They help improve joint flexibility and muscle strength. This makes it easier for those with AMC to move around.

Passive Stretching Methods

Passive stretching is a mainstay of AMC exercises. It involves gently moving joints without using muscles. Doing these stretches 3-5 times a day, for 20-30 seconds each, is best¹¹.

AMC stretching exercises

Active Movement Exercises

Active movement exercises strengthen muscles and improve function. They help patients move their joints on their own. Regular practice boosts daily activity skills.

Joint Mobilisation Strategies

Joint mobilisation is vital for better joint alignment and flexibility in AMC patients. Physiotherapists use manual techniques to increase mobility. Using joint mobilisation with other techniques can lead to better AMC management¹².

“Consistent application of range of motion techniques is key to improving mobility and quality of life for individuals with AMC.”

These techniques should be part of daily routines and adjusted as the child grows. With the right use of these strategies, many AMC patients can become more independent in daily tasks¹¹.

AMC is not a progressive disorder, but early and consistent treatment is crucial. It prevents further joint problems and improves function¹². A team approach, including physical therapy, stretching, and sometimes surgery, offers the best results for managing AMC and improving joint function.

Strength Training and Muscle Development

Strength training is vital for strengthening AMC muscles and improving motor skills. Physical therapists create special exercise plans. These plans focus on building functional strength, especially for head control and moving limbs.

These programmes aim to encourage active movements. This is important for kids with arthrogryposis to avoid being too still.

Starting early is crucial for kids with AMC to build strength. Therapists use fun play to help improve big motor skills. This helps kids reach important milestones like walking and grabbing¹³.

As kids get older, their strength training plans change. They help kids become more independent in daily tasks.

Functional strength training is part of daily life and play. It helps kids with AMC get stronger while doing fun things. They learn to control their limbs and improve core stability through these exercises.

Age Group	Focus Areas	Exercise Types
Infants	Head control, trunk stability	Tummy time, supported sitting
Toddlers	Standing, walking	Assisted squats, supported stepping
School-age	Coordination, balance	Obstacle courses, light resistance exercises

Physical therapy is key for kids with AMC. It helps a lot with physical growth, improving coordination and balance¹³. These customised exercise plans not only make moving easier but also boost kids’ confidence and independence.

Orthotics and Assistive Devices

Orthotics and assistive devices are key in managing Arthrogryposis Multiplex Congenita (AMC). They help improve mobility and correct malpositions. This enhances the quality of life for those with AMC.

Types of Orthoses

AMC orthotics come in different forms to meet specific needs. Ankle-foot orthoses (AFO), knee orthoses (KO), and knee-ankle-foot orthoses (KAFO) are common. These devices support joints, improve alignment, and aid movement.

Children using KAFO with locked knee joints show different trunk movements. This is compared to those using KAFO with open knee joints or AFOs¹⁴.

Custom Splinting Solutions

Splinting is vital in managing AMC. Custom-made splints address complex joint contractures. They help improve range of motion and prevent deformities.

The time spent wearing splints varies. It can be from 6 to 22 hours daily, based on individual needs.

Mobility Aids Selection

Choosing the right mobility aids is crucial for AMC patients. Walkers, wheelchairs, and other devices support independent mobility. These aids are tailored to accommodate upper limb limitations common in AMC patients.

Many children and adults with AMC need electric wheelchairs. This is due to stiffness in the legs¹⁵.

Device	Purpose	Customisation
AFO	Ankle support	Adjustable straps
KAFO	Knee and ankle support	Locked/open knee joints
Electric wheelchair	Independent mobility	Adapted controls

Using the right orthotics and assistive devices, along with physiotherapy, can greatly improve mobility for AMC patients¹⁵. However, satisfaction with orthoses can vary. Children reliant on them for walking may feel less satisfied with their weight¹⁴.

Despite this, these tools are vital. They enable children with AMC to walk, even with severe weakness and contractures¹⁴.

Treatment Strategies for Infants

AMC infant care aims to help babies move and get stronger early on. Babies with AMC often have trouble moving and have weak muscles in many joints. Physical therapy is key in helping them overcome these challenges.

Positioning Techniques

Getting the right position is crucial for babies with AMC. Therapists use special casts and supports to gently stretch muscles and joints¹⁰. This helps keep muscles from getting too tight and improves joint movement.

For support in the legs, they use lightweight casts like ankle-foot orthosis (AFO), knee orthosis (KO), or knee-ankle-foot orthosis (KAFO)¹⁰.

Early Movement Facilitation

Therapists use soft massages, stretching, and exercises to help babies move early¹⁶. These steps help move joints, increase range of motion, and boost brain and motor skills. Starting early is important because it links to how well babies can move later on¹⁰.

Parent Education

Teaching parents is a big part of AMC care for babies. Therapists teach parents how to do exercises at home and fit therapy into daily life. This ensures babies get care all the time and get the most from early help.

Intervention	Purpose	Frequency
Gentle massage	Improve circulation and flexibility	Daily
Stretching exercises	Increase joint mobility	2-3 times daily
Passive ROM exercises	Maintain joint flexibility	3-4 times daily
Positioning therapy	Prevent contractures	Continuous

Early and tailored care is vital for babies with AMC. Research shows early therapy can improve joint movement without surgery¹⁶. The goal of care should cover body, activity, and participation levels for full support¹⁰.

Rehabilitation During Toddler Years

AMC toddler therapy helps kids become more independent and solve problems. Physical therapists work hard with children who face delays, chronic issues, or injuries. They help these kids reach important milestones¹⁷. For toddlers with AMC, this time is very important.

Checking how kids walk is a key part of AMC therapy. These checks help figure out if they need special braces and spot any walking issues. Therapists then plan the best ways to help kids move better and care for themselves.

AMC toddler therapy session

Standing frames are used to help kids bear weight and stretch. Even though therapy might not happen as often in the toddler years, it’s still very important. Signs a child might need more therapy include odd walking, always tripping, or struggling to keep up with friends¹⁷.

Studies show that home exercises can help kids with AMC a lot. Kids did exercises about 2 times a week, and they met 12 out of 15 goals¹⁸. This shows how important it is to include home exercises in their therapy.

Physiotherapy is a big part of helping kids with AMC. It helps stop symptoms from getting worse and makes kids more independent². Therapists use exercises, massage, and stretching to improve kids’ ability to do things on their own and their overall happiness.

School-Age Physical Therapy Interventions

Physical therapy for school-age children with Arthrogryposis Multiplex Congenita (AMC) aims to boost mobility, strength, and independence. These efforts are key to enhancing their quality of life and school performance.

Classroom Adaptations

AMC school adaptations are vital for a welcoming learning space. Computers, laptops, and special tools like keyboards and wrist supports help students with AMC do better in school¹⁹. Physiotherapists help set up desks and seating to meet each child’s needs.

Physical Activity Modifications

Modifying physical education is crucial for kids with AMC to join in school sports. Activities like swimming, bowling, and horseback riding help improve strength and mobility²⁰. Yet, some kids might struggle due to leg issues¹⁹. Tools like splints, casts, and paddles can help in these activities²⁰.

Independence Promotion

Helping kids with AMC become more independent is a main goal. Occupational therapy helps with daily care and independence skills²⁰. For those with severe leg problems, wheelchairs might be needed for school mobility. Powered chairs can offer more freedom for those with both arm and leg issues¹⁹.

It’s important to start early with skills like thinking and socialising to help AMC students overcome job challenges¹⁹. Through physical therapy, kids with AMC can fight fatigue and fully engage in school life²⁰¹⁹.

Maintaining Mobility in Adolescence

For young people with Arthrogryposis Multiplex Congenita (AMC), keeping mobile is key for their health and freedom. A study showed that teens with AMC fell more often (89.3%) than adults (57.5%) in a year. This shows the importance of special care for AMC teens²¹.

Physical therapy is vital for AMC management. It helps keep joints flexible and muscles strong. Therapists use various methods like kinesitherapy, massage, and stretching to aid mobility². For some, using electric wheelchairs can save energy and increase community involvement.

Studies found that certain factors can lower the risk of falls. These include spinal involvement, past spinal surgery, and using a wheelchair in the community²¹. This knowledge helps create custom mobility plans. With AMC affecting 1 in 3,000 to 5,000 births in the U.S., ongoing research is crucial for better mobility strategies²².

As teens grow, their bodies change. Regular check-ups and updates to treatment plans are needed. Healthcare teams aim to improve teens’ independence and quality of life as they move into adulthood.
