Paranasal sinuses of the empty space is filled with air that exists in the bones in the face. However, the pus becomes inflamed paranasal sinuses sinusitis onset brings the voice of change, and complained of headaches and lethargy. Therefore, in this paper, paranasal sinuses related diseases to predict voice analysis parameter as measured by changes in paranasal sinuses through external stimuli is investigated and carried out a study to analysis the function consisting of the frontal sinus, ethmoid sinus, maxillary sinus, sphenoid sinus. From this, cold pack stimulation in the paranasal sinus area for stimulation before and after voice was performed by measuring formant frequency and external stimuli through correlation analysis of the mutual impact on paranasal sinuses were analyzed.

Total knee arthroplasty is performed widely in degenerative arthritis of the knee joint, and the frequency of use is increasing. Efforts should be made to achieve functional recovery, such as returning to daily life, and the recovery of strength and range of motion after surgery. The procedure should be approached from a range of perspectives, such as patient factors, surgical technique and rehabilitation. The patient's age, degree of obesity, sex, and strength of the quadriceps muscle can affect the functional recovery after surgery. In addition, the patient's mental state, such as expectation value and satisfaction, can also have an effect. For functional recovery, patient education, pain control, and strengthening of the quadriceps muscle can be performed prior to surgery. Postoperative physiotherapy, such as icing and compression, transcutaneous electrical nerve stimulation therapy, neuromuscular electrical stimulation therapy, low frequency low intensity magnetic field therapy, strengthening of quadriceps muscle, and range of motion exercise can also be applied. In recent years, hydrotherapy, which restores the strength and balance of the leg, is being performed increasingly. These treatments are not only performed shortly after surgery, but are also performed continuously. In addition, the surgeon should apply it appropriately considering the patient's condition, compliance, and social and psychological conditions.
