Objective:To observe the short-term efficacy of massaging quadriceps on knee osteoarthritis (KOA).
Methods:Totally 30 KOA patients were enrolled and treated mainly with massaging quadriceps, 20 min for each session, once a day, 2 weeks as a treatment course, and for 2 courses in total. After treatment, the changes of visual analogue scale (VAS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC) were observed.
Result:The VAS and WOMAC scores dropped after treatment, with a statistically significant difference (P<0.01). After a course of treatment, the recovery rate was 33.3% and the total effective rate was 86.7%; after 2 courses, the recovery rate was 60.0% and the total effect rate was 96.7%.
Conclusion:Massaging quadriceps can alleviate pain, improve the function of knee joint, and produce a significant short-term efficacy in treating KOA.

Summary: Structural nasal obstruction（SNO） is a series of diseases caused by congenital or acquired structural anatomical abnormalities of nasal airway and its surrounding tissues, which leads to increased nasal ventilation resistance. The effect of medication drugs for SNO is poor and surgical intervention is often needed. However, the abnormal structure of nasal airway is very complex, including the periphery of nasal airway, internal nasal airway, the front and rear of nasal airway and complex factors. These abnormal structures may interfere with the nasal airflow mechanics by changing the nasal ventilation volume and disrupting the symmetry of the bilateral nasal cavity, and finally lead to subjective feeling of nasal obstruction. In addition, the structure of nasal airway has plasticity. After the abnormal structure appears, the corresponding compensation of nasal airway can occur to ensure normal nasal ventilation and bilateral nasal cavity symmetry. Therefore, the SNO is the result of the failure of nasal airway remodeling after the appearance of abnormal structures. The etiology of SNO is complex, involving original structural abnormalities, nasal symmetry changing and nasal airway structure remodeling. Therefore, accurate identification of the main factors leading to SNO is the vitalpremise of making personalized nasal ventilation surgery.
