Prosthetic socket is the connection part between the human body and the prosthesis. Prosthetic socket directly affects the patient's comfort with the prosthesis. Today, MEDI-REHATEK will introduce a comfortable prosthetic socket technology, so that patients can "perfectly" fit with prosthetic limb. ![]() This prosthetic socket is called the ischial containment prosthetic socket. The socket mouth is like kind of longitudinal oval figuration , which is different from the conventional square-shaped thigh prosthesis socket, that is the horizontal elliptic socket. They differ largely in the shape and method of cast. ![]() So what is the difference between this socket and the usual socket, or what is the features? 1, The distance between internal and external wall is short The short difference direct supports the alignment of adduction of the femur. If this containment is not narrow, adduction control will be very difficult because of soft tissue, which can not produce direct support on the femur. ![]() 2,Three-point pressure system The middle part of residual limb forms a three-point pressure system between the proximal end of prosthetic socket and the ischial containment.The three-point pressure system keeps the femur adduction, stabilizes the pelvis, and then changes the force of socket. ![]() 3,Pulling off the pressure pad on the front side It is suitable for elderly patients and patients with vasculitis,that is also suitable for patients with strong movement and patients with shorter stump . 4, The flexible materials , The prosthetic socket is made from flexible materials.Patients feel very natural when walking and sitting. Pay attention to the difference of adaptation of residual limb soft tissue.

![]() In recent years, patients with upper limb amputation are basically assembled with myoelectric hand.Nobody cares the mechanical hand that was widely popular before step by step. So what are the advantages of myoelectric hand comparing with mechanical hand on earth? Here, MEDI-REHATEK will give you a detailed description of some configuration, features and advantages of myoelectric hand. Myoelectric hand is the prosthetic hand that is controlled by body muscle signal, it is not like the mechanical hand that needs a large body movements to make artificial limb complete the specified action. The former one controls residual limb muscles that produce weak signal through the human brain. Then it will have analysis, amplification of weak signal in order to control the prosthetic activity . ![]() Therefore, before the myoelectric hand assembly,patients are required to have EMG test in the rehabilitation center, which needs to test which muscle signal controls the grasp action, which signal control the open and close action and so on. After the EMG test, and then the signal in the prosthesis needs matching the patient’s body in order to achieve precise control of the signal effects of artificial limbs. ![]() Myoelectric hand controls the prosthesis by the muscle signal, so the reaction speed is very fast, you can quickly meet the needs of patients. After general rehabilitation training,patient can easily control the upper limb prosthesis, and correctly grasp the objects.It offers a great help for patients on daily life . ![]() Medi-Rehatek will continue to introduce basic training of upper limb prostheses. Patients with double hands amputation needs prosthetic hands at the same time who need to choose the appropriate self-help equipment: such as the life sleeve commonly used by double upper limb amputees, that can be covered on the stump, and then insert spoon or pen, amputee can eat or write; ![]() Patients can not use chopsticks by prosthetic hands, who can only use spoon or fork that is bent into the appropriate angle; Patients should co-operate with both hands to comb hair with thick hand grip; ![]() When taking things out from clothing pocket by prosthetic hand,amputees pull the bottom from pocket with one hand, use the other hand to fetch. It is best to use the left hand to take things out from pocket of the right side, with the right hand to take things out from the pocket of left side; ![]() Appropriate to change the used items: add a large pull ring on the zipper,the prosthetic hand can open; Velcro buckles are sewn on the clothes to avoid the trouble; elastic shoes don’t need the shoes lace and so on. Relative blog: Congenital hip dislocation Choosing A Reasonably Priced Thigh Prosthesis ![]() Today Medi-Rehatek will introduce the practical training for upper limb prosthesis. The selection for primary hand : Normal hands, also have the primary and secondary use, the majority of people give priority to use the right hand (also known as dextromanuality). Upper limb amputation, if it is unilateral, the amputation of the primary hand can only be a sound hand, the prosthetic hand only can be an assistive hand. Prosthetic hand training should focus on the co-operation action between two hands . If the amputation of both hands,patient should choose the residual limb with good condition and better prosthetic hand function as primary hand. ![]() Practical Training of Upper Limb Prosthesis: The first is to train amputees to become familiar with prosthesis and prosthetic control systems. Then, the opening / closing motion of the hand portion is initially trained. First on the bench patients do a simply open and close action for daily life training, and then increase the level of training and change the action until the patients master them. Opening and closing action training should go from the most simple action like pick up the object slowly until patient is skilled. ![]() When patients are familiar with these two important basic training process,we can teach patients how to make their residual limb co-operate with the prosthesis to have practical training in order to achieve the most basic needs of life such as take on and off clothing, personal hygiene (wash, go to bathroom, take a bath), open and close door,switch on and off the appliance,cook,write with pen,call, etc., and then transition to the study, work training. Upper limb prosthesis training for amputees with unilateral arm amputation is not too difficult, but it is too difficult for amputees with double arms amputation. As the function of current upper limb prosthetic is still relatively simple.Amputees need hard training in order to adapt to the needs. ![]() Relative blog: Common misunderstanding of wearing back brace Choosing A Reasonably Priced Thigh Prosthesis ![]() Medi-Rehatek will introduce the basic training of upper limb prosthesis. Generally as long as the prosthetic socket of residual limb is appropriate, the strap does not require training when its use is appropriate. But the first installer should learn to methods of wearing, teach patient the most basic wear and passive wrist rotation with prosthetic hand and the method of hand opening and closing. However, upper arm amputees should learn to use passive control of the elbow lock. Cable-controlled and electric prostheses are functional prosthetic hands, the difference is that the former one is using its own power, the latter one is using external power. In order to improve the use of these hands,patients are required to use under the correct guidance and training. ![]() 1)Training for wearing on and off prosthesis; Putting the residual limb into prosthetic socket firstly, and then patients put the sound limb through shoulder strap.It is the contrary to wear off the prosthesis. 2) Prosthesis manipulation training Training for hand opening and closing : For example, cable-controlled prosthesis relies on both shoulders that flex forwards forcibly, and the prosthesis is closed by elastic force. Forearm myoelectric prosthesis touches the sensor via forearm flexor and extensors, the signal can make the hand open and close through the sensor ![]() Elbow flexion, elbow open and close training: When both shoulder have abduction, lifting up and down, the elbow can be closed on cable-controlled prosthesis The elbow can be freely and passively flexed and extended when the shoulder controls the flexion and extension on the sound stump. Some cable control prosthetic hand has the device that offers friction on wrist rotation, bolt on wrist flexion, you can adjust to the desired location. ![]() Medi-Rehatek will introduce the maintenance of energy storage prosthetic foot. 1, Carbon fiber core of prosthetic foot is covered a layer of Lycra to prevent dust and debris immersion. If Lycra is damaged, it should be replaced. General foot plate has a waterproof performance, but if the foot plate is soaked, foot plate and foot pad should be washed by clean water and foot pads, and dry as soon as possible. ![]() 2, it is recommended that patients choose the rigidness of feet plate in accordance with the "Model Selection Table" as well as according to the amputee body weight and daily activity level. If the amputee needs higher than average activity level or lifting weight as part of the daily life, the rigidness of foot plate should be increased. ![]() 3, The foot plate cover should be regularly (weekly) cleaned with a soft cloth, soap, water.If the prosthesis does not use sponge packaging, we need to check whether there is sand or other debris in foot plate cover. Foot cover can also be cleaned with topical alcohol (70% purity). Foot cover can not be scrubbed with acetone, otherwise it will damage the foot cover coating. ![]() 4, if the foot plate has abnormal function or sound, you should immediately contact with the prosthetic technician to promptly correct the problem. All prostheses should be checked regularly every 6 months. ![]() Many patients are in the progress of below-knee prostheses assembly, prosthetic technician will generally recommend energy storage prosthetic foot, because this type of feet can let prosthetic patients cost less effort to walk quickly. What is the original characteristic of this type of prosthesis ? Here, MEDI-REHATEK will give you a detailed introduction. ![]() Features and principles of energy storage prosthetic foot: 1, Stored energy will release when the heel touches the ground and forefoot leaves leave the ground in middle support phase. 2, This prosthetic feet use composite materials, is combined with unique functional foot plate structure.When the heel touches the ground,the foot plate is pressurized to deformation, so as to promote the loading response. ![]() 3,The prosthetic foot with efficient storage and release energy so that patients cost less effort to walk fast and quickly. ![]() Rehabilitation training for patients with forearm amputation in early phase that is very important, MEDI-REHATEK today mainly talk about the elbow flexion training. When the elbow moves, the distance between cable hook of strap and control cable of hand is shorter, elbow comes back to flexion after wearing artificial limbs. ![]() This action synchronizes with forearm prosthesis does. When patient does this action for the first time, pay attention to the strength of controlling, if produces the excessive force that will make elbow flexion suddenly, the hand will hit the patient's face. Therefore, rehabilitation training need to be in accordance with the following steps: ![]() 1, Let the elbow move 2, The rehabilitation doctor put one hand on the patient's shoulders, the other hand holds the patient’s hand 3, Keeps elbow in flexion position at 90 degrees, let patients confirm whether the control cable is loose ![]() 4, Let patients maintain this position, release the patient’s hand. 5, Then patient slowly pushes the forearm back, back to the original position, confirms whether the forearm is sagged. 6, Repeat this action, transform the angle and speed of flexion ![]() Medi-Rehatek will introduce the simple walk training after prosthetic installation as below: Patients with amputation don’t rely on use of crutches and other auxiliary equipment to walk as far as possible.Because the use of crutches will have a great influence onthe walking gait after prosthesis installation , that also easily leads to the patient's pelvis scoliosis. So in the early phase you should allow patients to stand with singleleg, jump with single leg and other training methods. ![]() We suggest that elderly patients have support training after the installation of artificial limbs under support of the balance bar.Young patients master balance,don’t use the auxiliary of balance bar. In training, the heel and toe do the rotation,patient do a variety of restoring balance training, the pelvis lifts up, knee flexion and stretching exercises, etc., so that patients will be faster to adapt to the walking with prosthesis, to maintain a good gait. Medi-Rehatek continues introducing the part II of go upstairs and downstairs training alternately for thigh prosthesis. ![]() Second,go downstairs training Going upstairs training is the contrary to going downstairs training. The prosthesis leg goes down the step firstly, the the sound leg goes down the step, that is parallel to the prosthetic leg. This exercise training requires the sound leg to have muscle strength that supports the weight in a certain degree of knee flexion.So it requires the sound leg to maintain knee flexion for a few seconds during knee flexion and stretch training. ![]() Third, both legs alternately up and down the stairs training The training is appropriate for unilateral thigh prosthesis patients with certain muscle strength on the sound leg and residual limb and suitable length of residual limb length. When doing the training, the stability of knee determines the position of the prosthetic foot after stepping on the step. The foot needs to be close to the edge of step( It depends on the stability of the knee that is assembled on patient). In this case, the distal end of single axis knee joint should touch the edge portion of the step initially, and the heel portion is lifted to the edge of the step when using the stable knee joint. |
