Abstract: Objective(s): To analyze the therapeutic effect of chronic use of the flexible, nonheeled commercial shoe Moleca® on clinical aspects of women with knee osteoarthritis (OA). Material & Methods: Six women with an established diagnosis of knee OA according to ACR criteria were evaluated after assignment of approved informed consent. The intervention consisted of the use for a 6 month period of Moleca® footwear (RS, Brazil) for at least 6hours daily and for 7 days a week. This is a light (mean weight=172±19.6 g, range 142-193 g depending on size) double canvas flexible flat walking shoe nonheeled, with a 5-mm antislip rubber sole and a 3-mm internal wedge of ethylene vinyl acetate. Assessment was done at baseline and 6 months later. All patients were screened and evaluated by a rheumatologist at baseline for clinical examination and x-rays. Subsequent procedures were performed by the same physiotherapist to assess pain (visual analogue scale–VAS), WOMAC index and knee adduction moment during gait calculated by inverse dynamics method using 6 infrared cameras and a multicomponent force plate. T-test was used to compare pre/post intervention effects and P<0.05 was considered significant. Results: Mean age of patients was 69±6 yrs, weight=65.9±12.1 kg, height=152±5 cm, BMI=28.6±4.9 kg/cm 2. Allwomen had knee OA grade 2 or 3 (Kellgren-Lawrence). Average use of Moleca® was 7:24±3:47 h monthly. Remarkably, 6 months after intervention, a reduction of 56.6% and 73.9% of VAS for pain at night and at the moment of assessment, respectively, was observed (P=0.048 and P=0.015). Total WOMAC score diminished 44.9% (p=0.001), WOMAC pain subscale decreased 55.2% (p=0.015), and WOMAC function index improved 43.6% (p=0.004). The first (p= 0.533) and the second (p=0.686) knee adduction moment peaks were alike, while significant reduction of 11.2% in knee loading (p=0.001) was achieved during midstance. Conclusion(s): We have demonstrated in this pilot study that elderly women with knee OA have a benefit effect on pain and function following a 6 month period of use of a specific flexible, nonheeled shoe. These preliminary results warrant further studies aiming to evaluate long term benefit of this intervention in a larger sample population.
