Upper limb orthotics are widely used in foreign countries, and there are hundreds of shapes and types of them. The upper limb orthotics mainly limit the wrist and hand, including rest position splint, wrist functional splint, posterior thumb splint, ring finger splint and dynamic splint.The basic function of current upper limb orthotics is to provide traction to control or correct deformities and prevent muscle and joint contracture.Support paralyzed limbs, compensate for lost muscle strength, and maintain and fix limbs in functional position;Help weak body move, etc.
I. The main role of upper limb orthosis
The therapeutic advantages of upper limb orthotics depend on the clinical need to effectively choose to limit, assist, or create movement.
Proper use of these features can make a significant contribution to the achievement of the following objectives through the appropriate combination of static, moving, and dynamic orthotic components:
① Prevent or correct deformities.
② Protects painful, inflammatory, and healing tissues.
③ Adding function to assist or compensate for inadequate muscles to stabilize structurally unstable joints.
④ Stationary orthotics are rigid structures that keep the body in an ideal position.
⑤ Moving orthotics have joints that allow the patient to move by his own muscles or some external source of power. The design and alignment of the joints determine the permissible motion plane and arc, while the brake can further limit the arc of motion.
2. Basic functions of upper limb orthotics
① Fixed function
Also known as static function, it immobilizes the joint or fracture site and promotes healing of the lesion or tissue.
This kind of orthopedic appliance is used to fix limb function, limit limb abnormal activity, restore upper limb function, and is suitable for inflammation of upper limb joint and tendon sheath, traumatic injury, etc.
② Walking function
Also known as dynamic function, these orthopedic devices are used to prevent the occurrence of upper limb deformity and joint hyperextension, and to ensure postoperative results and normal bone development during development.
③ Correction function
Also known as orthopaedic function, prevent and correct joint deformities.
This type of orthotic is used to control the development of deformity by applying only a small amount of force to the fingers, wrist, elbow and shoulder joints without pain.
④ Compensatory function
Also known as enhancement function , compensates for lost muscle function.
These orthotics use elastic devices such as springs, elastic bands, plastic elastomers, or pneumatic, electric or cable control devices to strengthen the movement of fingers and train muscle strength.
This includes the use of assistive tools and self-help devices to help paralyzed people regain their functions.
⑤ Protective function
Protect weak muscles.It can protect the upper limb which is vulnerable to injury or lesions, prevent the hyper extension or strain of joints and tendons, promote the healing of lesions, and also protect some surgical scar sites.
From simple wooden splints to complex suspension and traction devices belong to this type of deformity.
