Development direction of clinical orthosis

In recent years,MEDI-REHATEK has learned that with the rapid development of the national rehabilitation medicine and the national career of the handicapped, government departments and the rehabilitation medicine circle have a considerable attention on orthosis assembly. The career plan of the disabled takes the yearly number of assembling prosthesisand orthosis as task index "There are organic integration and system services amongphysical disability rehabilitation focusing on corrective surgery, prosthesis and orthosis assembly, functional training. ", " to strengthen the level of orthopedic writing for medical unit. " These specify development direction and determine the exact tasks,develop the important measures for our national orthosis work.

Early in accordance with the traditional concept, orthotics mainly refers to a variety of orthopedic braces for upper and lower limbs and trunk , orthopedic shoes, andsupports for inner organ and so on. But in recent years, it has been expanded to new ranges, such as a variety of canes, crutches, other mobility aids, special cushionsand bed mattresses of improving support and other orthotic devices besides the above-mentioned range . In addition, some modern science and technology has also entered the field of orthotics, such as electric and pneumatic orthosis, functional electrical stimulation, biofeedback, mechanical devices of inner body and environmental control systems etc.

The development of orthosis assembly should be focused on expanding the fitting of orthosis . To meet the increasing demand of the disabled for orthosis, local hospitals, rehabilitation centers, comprehensive service institutions for the disabled should establish the orthosis fabrication and assembly room that is closely related with clinic for the disabled. We should enhance the development of spare parts of orthosis,special material and equipment.Orthosis should be standardized with serialized production on development of component-based product.

A good blog of Design concept of Carbon Fiber orthosis,I think you guys should learn about it.

Carbon fiber orthosis for the disabled

  The compound disability is more common at the experience of our actual work. Such as one side amputation may lead various movement dysfunction of injured lower limb without amputation in the other side. Although prosthetic assembly can let the patient stand up, the dysfunction of other side has serious impact on the effect of rehabilitation.This time needed orthosis can cooperate to achieve the best recoveryresults. MEDI-REHATEK would like to introduce a more typical case for the disability in this chapter.

  The patient has severe injuries resulting in the amputation of the left leg and severe damage of the right ankle. The ankle joint was cleared off and had fusion surgery with the portion of shank in hospital( see postoperative X-rays). Although this kind of surgery retains the complete lower extremities, the heel can’t touch the ground due to the lack of the ankle joint when standing by himself. He can not reach a dynamicbalance of the body with prosthesis installing in the left leg. After taking into account of the synthesis of patient, we decided to carry out comprehensive rehabilitation for right leg to assemble orthosis in our rehabilitation center.

MEDI-REHATEK would like to introduce a good blog of the advantage of Carbon Fiber AFO. 

Poilo children wearing carbon fiber orthosis

Polio sequela usually causes motor dysfunction of the lower extremities. Recently MEDI-REHATEK received a polio patient,who has muscle paralysis in lower leg section and severe muscle spasm in posterior leg and sole of foot after inspection.At the same time, knee and hip presents apparently compensatory flexion contracture after tiptoeing with claudication for nearly 30 years.Patients can not lift the instep due to muscle spasms when walking via the gait analysis.Hip needs carrying over high so that the affected legs can be put the front side of the body with knee flexing over in the swing phase. It completes the walking motion relying on the rotation of the whole body as the foot is not flat with tiptoeing in the stance phase.The other foot has the tendency of foot varus.

After symptom and gait analysis, orthopedic program for the polio patient must meet the following design requirements:

1, Orthosis can well withstand severe spasm of rear leg and sole of foot muscle;

2, To ensure the stability of the ankle joint in normal physiological position when walking;

3, To correct the deformity of knee flexion through daily walking ;

4, Instep should maintain a good physical position;

5, Orthosis is easy to wear, with beautiful appearance,hidden meanwhile ensuring sufficient structural strength;

6, Orthosis can meet the requirements of longtime wearing.

Usefulness and benefits of orthotics

Orthotics is widely used in bone and joint tuberculosis, joint dislocation, bonefractures, arthritis, Lumbar disc herniation, scoliosis, neck/arm/back/leg pain or limb and joint deformities. That is good rehabilitation for the disabled, especially treatment for nerve, muscle, bone and other movement disorders.

MEDI-REHATEK will introduce more detail about orthotics as below:

The main role of orthtotics is : ① restrict limb movement, maintain joint with stability ② correct deformities and prevent abnormal development ③ traction, relieve symptoms ④ load-free functionin relieving pain ⑤ decompensation in assisting limb movements ⑥ protection, prevention of tissue damage.

The function of orthotics: good treatment, simple structure, lightweight, durable, safe, reliable, easy to wear, tenderness and no other side effects, does not affect jointmovement, good ventilation, easy to keep clean.

Artificial limbs mainly apply to various amputation planes( shoulder/upper arm/elbow amputation, forearm/wrist amputation, hip amputation, thigh/knee amputation, shank/ankle and partial foot amputation) of the disabled who need assembling various functional and decorative prostheses and providing the service of prothesis function training.

A good blog of Innovative technology makes polio patient walk,you should visit.

How to make polio patient walk

The sequela of polio usually has irreversible damage on the function of lower extremity motor. Limb deformity and limitation of movement are the biggest impact on polio patients. The goal of rehabilitation is to help rebuild movement function ofpolio patients and get away from crutches to walk freely. Rehabilitation engineering experts develop a technical solution to effectively help polio patients through unceasing exploration of new material and technique.This article is a typical case of special orthosis from MEDI-REHATEK applying to polio patient.

Patient’s briefings:

Male patient aged 28 years, was diagnosed as polio when he got the high fever at the age of 8 months. He had surgery at the childhood. Unequal length of bilateral lower extremity is inspected before installing orthosis, left side is 11CM shorter than the right side. Hip growth is not complete as well as the left limb without muscle strength.Force leads plantar subluxation.There are less than 10°of knee flexion contracture. Ankle turns inversion and droops.X-ray examination showed poor bone quality. The development of right lower limb is more complete, hip morphology and muscle strength are normal.Knee morphology is normal but with weak muscle .It autonomously stabilizes the ankle joint when the knee is upright.Ankle morphology is normal without muscle strength, droops when walking; He walked with walking cane before installing orthosis.

The design idea of MEDI-REHATEK orthosis:

1 Lengthen the left side extra 10 cm to fix the problem of unequal length of bilateral side ,to avoid affecting the spine morphology;

2. Fix the left knee to create natural conditions for stand by himself;

3, Moderately bearing-free design for left limb, to avoid pressured or pathological fractures due to force on poor bone;

4, The main load-bearing parts of left side is transferred to the plane of the ischium, to ensure without dislocation of the hip when the force on left side;

5, The rolling device on insole ensures the stability meanwhile people can easily walk over;

6, Hidden design in shoe can keep design features also with an aesthetic appearance;

7, The correction for flexion contracture on the left knee creates better physical condition for the secondary assembly;

8, Correction for foot varus, control droop and slightly spasm;

9, The use of dynamic ankle-foot orthosis is for foot drop and varus;

10, The rehabilitation goal is to let patient be away from the crutches and walk independently.

A good article about Diagnosis for Congenital hip dysplasia,that is useful for patient with congential hip dysplasia.

How to diagnose congenital hip dysplasia

Congenital hip dysplasia includes congenital dislocation of hip (CDH), congenital dysplasia of the hip (DDH).

MEDI-REHATEK has a simple statistics with 10 years experience, winter and caesarean birth traditional method of tying-feeding baby have the higher incidence of congenital hip dysplasia , the north is significantly higher than the south.

How do parents observe whether children have congenital hip dysplasia? Usuallythere will be DDH screening like developed city Shanghai.Parents should have body check with the baby aged below one year.

1. Are gluteal lines symmetry? That is wrinkle between the thighs and buttocks.Some show with more lines on lateral side, some with unequal length of the gluteal lines on both sides.

2. Is there that the lateral leg doesn’t act in usual activity ? The side or even on both sides of leg is not flexible when kicking.

3.whether the child can stand during the period of standing? Baby aged 8-9 monthsshould be able to stand with handrails. Some show with the lateral side of leg suspending,so some can’t stand when standing.

If encountering these situations, parents should draw attention and bring the children to inspect in Children Hospital. To screen whether there exits DDH.

If children have congenital dislocation of hip (CDH) or congenital dysplasia of the hip (DDH),MEDI-REHATEK would like to introduce Children Hip Abduction Orthosis as an alternative treatment.

Recently a good article of Hemiplegic patients need AFO,we suggest that you should visit there.

How to wear AFO correctly II

The athetosic children with Intermittent spasm and unstable tension will feel unwellwhen wearing in the beginning.The children will adapt soon according to the method above. 

The method of wearing lower limb orthosis when crawling:

Children find it difficult to crawl with AFO as orthosis prevents ankle from plantar flexion. He can only flex knee further, increase the external rotation degree of hip to crawl forward. Crawling is the primary method that children can move meanwhile explore at the present stage.Children had better take off orthosis when training.

 Caution for siting a long time: The children with AFO may sit on the floor unstably as they often have tendency "W" to sit also AFO will cause instability.Therefore, we must let the child sit on a chair or take off the AFO when they sit a long time.

Sometimes,doctors would like to recommend the AFO from MEDI-REHATEK.

Recently a good article of Wear AFO correctly that shows more detail about wearing AFO.
