Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical auxiliary appliance, especially relates to a PT stool for assisting knee joint loosening physiotherapy. BACKGROUND

[0002] Knee joint adhesion refers to the adhesion of internal or peripheral tissues of the knee joint due to various reasons (such as surgical trauma, inflammation, long-term immobilization, etc.), which limits the range of motion of the knee joint. This adhesion can occur between soft tissues such as muscles, ligaments and joint capsules, or between bones. Symptoms of knee joint adhesion may include joint stiffness, pain and swelling. Some patients choose physical therapy for the knee joint to relieve symptoms, such as joint mobilization. The purpose of knee joint mobilization is to increase the range of motion of the knee joint, such as flexion, extension, rotation, and to reduce tension and adhesion around the joint. Common knee joint mobilization techniques include: femorotibial joint mobilization, patellofemoral joint mobilization, and tibiofibular joint mobilization.

[0003] When performing physiotherapy on the knee joint using joint mobilization, in order to improve the range of motion of the knee joint flexion, femorotibial joint mobilization is performed in a sitting position after patellofemoral joint mobilization and tibiofibular joint mobilization, and passive quadriceps femoris stretching is performed at the same time. After completing a set of joint mobilization, the patient's knee joint is advanced by a certain angle, and the new angle is maintained for tens of seconds to several minutes, then relaxed, and the operation is repeated until the patient's rehabilitation goal is reached. In traditional operation, the therapist needs to hold the lower end of the patient's lower leg and continuously apply downward and backward force to resist the forward stretching resistance generated by the patient's lower leg due to limited knee flexion angle, which is very tiring for the therapist, and the pressure applied by the therapist to the lower end of the patient's lower leg cannot be guaranteed to be stable and continuous within a few minutes. Therefore, it is necessary to improve the prior art and provide an apparatus that can assist therapists in performing sitting femorotibial joint mobilization physiotherapy. SUMMARY

[0004] Therefore, based on the above background, the utility model improves the prior art and provides a PT stool for assisting knee joint mobilization physiotherapy, which uses a support gap and a support plate to resist the lower leg from above and below, so that the therapist can stably fix the patient's lower leg when performing joint mobilization for the purpose of improving the knee flexion angle, achieving better physiotherapy effect, and saving the therapist's physical strength.
