简要总结
The purpose of this study is to determine whether inexpensive, flexible and non-heeled footwear is effective in improving of clinical, functional and gait biomechanics in elderly women with knee osteoarthritis.
详细描述
- The clinical and functional aspects will be evaluated using a visual analogue scale (VAS) for pain, Western Ontario and McMaster Universities (WOMAC) and Lequesne questionnaires of quality of life in patients with knee osteoarthritis and testing of six-minute walk (6MWT).
- Biomechanical analysis of gait will be performed by infrared cameras and a force platform. From the data of kinematics and kinetics, will be calculated moments of the knee joint strength by inverse dynamics.
The process (steps) will be divided as follows:
- step 1, in this step there will be sorting and initial assessment of potential participants; pain will be evaluated through VAS, function and quality of life by means of questionnaires WOMAC and Lequesne and the 6MWT, and by evaluating the biomechanics of gait.
- step 2,(3 month follow-up), both groups will be evaluated again by the VAS and WOMAC and Lequesne questionnaires.
- step 3, after 6 months of starting the monitoring process, both groups will be reevaluated through the VAS, WOMAC, Lequesne, 6MWT and biomechanical analysis of gait. This step is the final evaluation, characterizing the end of intervention.

结局指标
主要结局
Western Ontario and McMaster Universities (WOMAC) Pain Subscale
时间窗: 6 month
The WOMAC (Western Ontario and McMaster Universities) pain subscale consists of five questions (Likert Scale) relating to the patient's pain in everyday situations. The Likert Scale version used for all WOMAC items are: none, mild, moderate, severe, and extreme. The sum of all items of pain subscale ranges from 0 to 20. Higher scores indicate worse pain.
次要结局
- WOMAC Total Score(6 month)
- Paracetamol Intake(6 month)
- WOMAC Stiffness Subscale(6 month)
- First Peak of the Knee Adduction Moment (KAM) During Gait.(6 month)
- WOMAC Physical Function Subscale(6 month)
- Global Score of the Lequesne´s Questionaire Algo-functional.(6 month)
- Six-minute Walk Test(6 month)
