Description

EMS Knee Protector and Knee Orthosis {EMS KNEE BRACE AND KNEE JOINT ASSIST APPARATUS}

The present invention relates to an EMS knee protector and a knee orthosis, and more particularly, to an EMS knee protector and a knee orthosis that improve knee stability after cruciate ligament surgery or knee injury, combined with electrical muscle stimulation therapy.

In general, in the case of a patient who has undergone surgery due to damage to the knee joint, it is necessary to fix the damaged area with a cast or the like until the lesion area is recovered. When the cast is removed from the leg, the joint that has been fixed for a long time is hardened, so it takes a considerable amount of time to perform rehabilitation treatment.

Therefore, after cruciate ligament and knee surgery, a joint orthosis that holds the knee joint is essential, and is important for improving knee stability and function. A joint orthosis is a device that assists or corrects the surgical site due to rupture of the cruciate ligament, etc., and minimizes the movement of the damaged ligament to support the joint.

Various technologies related to knee orthosis are under research and development, and as a related prior art document, Korean Patent Application Laid-Open No. 10-2010-0018599 (published on February 17, 2010), a rehabilitation exercise device for knee orthosis is disclosed.

However, the knee orthosis of the prior art document has a problem in that it does not consider the patient's body type and the severity of the injury at all because the support is fixed to fix the joint by minimizing the movement of the ligaments. In addition, even though the damaged area is different for each patient, if it is maintained in a fixed state for a certain period of time, the joint is hardened and a lot of time is required for rehabilitation treatment.

On the other hand, the existing protector is a ready-made product and is very bulky and bulky. Therefore, there is a need for an orthosis that is simple and customized to the individual patient. In particular, recent studies have reported that the initial electrical muscle stimulation therapy is very important for the recovery of quadriceps muscle strength and future rehabilitation and functional improvement after knee surgery (Hauger et al.
