- The effects of plantar fasciitis and pain on plantar pressure distribution of recreational runners(2011) RIBEIRO, Ana Paula; TROMBINI-SOUZA, Francis; TESSUTTI, Vitor D.; LIMA, Fernanda R.; JOAO, Silvia M. A.; SACCO, Isabel C. N.Background: Plantar fasciitis is the third most frequent injury in runners. Despite its high prevalence, its pathogenesis remains inconclusive. The literature reports overload as the basic mechanism for its development. However, the way that these plantar loads are distributed on the foot surface of runners with plantar fasciitis and the effects of pain on this mechanical factor has not yet been investigated. Therefore, the aim of this study was to evaluate and compare the plantar pressure distributions during running in runners with symptom or history of plantar fasciitis and runners without the disease. Methods: Forty-five recreational runners with plantar fasciitis (30 symptomatic and 15 with previous history of the disease) and 60 runners without plantar fasciitis (control group) were evaluated. Pain was assessed by a visual analogue scale. All runners were evaluated by means of the Pedar system insoles during running forty meters at a speed of 12(5%) km/h, using standard sport footwear. Two-way ANOVAS were employed to investigate the main and interaction effects between groups and plantar areas. Findings: No interaction effects were found for any of the investigated variables: peak pressure (P=0.61), contact area (P=0.38), contact time (P=0.91), and the pressure-time integral (P=0.50). Interpretation: These findings indicated that the patterns of plantar pressure distribution were not affected in recreational runners with plantar fasciitis when compared to control runners. Pain also did not interfere with the dynamic patterns of the plantar pressure distributions.
- Long-term use of minimal footwear on pain, self-reported function, analgesic intake, and joint loading in elderly women with knee osteoarthritis: A randomized controlled trial(2015) TROMBINI-SOUZA, Francis; MATIAS, Alessandra B.; YOKOTA, Mariane; BUTUGAN, Marco K.; GOLDENSTEIN-SCHAINBERG, Claudia; FULLER, Ricardo; SACCO, Isabel C. N.Background: Efforts have been made to retard the progressive debilitating pain and joint dysfunction in patients with knee osteoarthritis. We aimed to evaluate the therapeutic effect of a low-cost minimalist footwear on pain, function, clinical and gait-biomechanical aspects of elderly women with knee osteoarthritis. Methods: Throughout a randomized, parallel and controlled clinical trial, fifty-six patients with medial knee osteoarthritis were randomly allocated to an intervention (n = 28) or control group (n = 28), and assessed at baseline and after three and six months. The intervention involved wearing Moleca footwear for at least 6 h/day, 7 days/week, over 6 months. The pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index was the primary outcome. The secondary outcomes were the other subscales, Lequesne score, distance walked in 6 min, knee oedema and effusion, knee adduction moment and paracetamol intake. Intention-to-treat analysis was performed using two-way casewise ANOVA (< .05) and Cohen's d coefficient. Findings: Intervention group showed improvement in pain (effect size: 1.41, p < .001), function (effect size: 1.22, p = .001), stiffness (effect size: 0.76, p = .001), Lequesne score (effect size: 1.07, p < .001), and reduction by 21.8% in the knee adduction moment impulse (p = .017) during gait wearing Moleca (R). The analgesic intake was lower in the intervention group. Interpretation: The long-term use of Moleca (R) footwear relieves pain, improves self-reported function, reduces the knee loading while wearing Moleca (R), refrains the increase of analgesic intalce in elderly women with knee ostearthritis and can be considered as a conservative mechanical treatment option.
