- 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.
- Inexpensive footwear decreases joint loading in elderly women with knee osteoarthritis(2011) TROMBINI-SOUZA, Francis; KIMURA, Aline; RIBEIRO, Ana Paula; BUTUGAN, Marco; AKASHI, Paula; PASSARO, Anice C.; ARNONE, Antonio C.; SACCO, Isabel C. N.Recent literature has highlighted that the flexibility of walking barefoot reduces overload in individuals with knee osteoarthritis (OA). As such, the aim of this study was to evaluate the effects of inexpensive, flexible, non-heeled footwear (Moleca (R)) as compared with a modern heeled shoes and walking barefoot on the knee adduction moment (KAM) during gait in elderly women with and without knee OA. The gait of 45 elderly women between 60 and 70 years of age was evaluated. Twenty-one had knee OR graded 2 or 3 according to Kellgren and Lawrence's criteria, and 24 who had no OA comprised the control group (CG). The gait conditions were: barefoot, Moleca (R), and modern heeled shoes. Three-dimensional kinematics and ground reaction forces were measured to calculate KAM by inverse dynamics. For both groups, the Moleca (R) provided peak KAM and KAM impulse similar to barefoot walking. For the OA group, the Moleca (R) reduced KAM even more as compared to the barefoot condition during midstance. On the other hand, the modern heeled shoes increased this variable in both groups. Inexpensive, flexible, and non-heeled footwear provided loading on the knee joint similar to a barefoot gait and significant overload decreases in elderly women with and without knee OA, compared to modern heeled shoes. During midstance, the Moleca (R) also allowed greater reduction in the knee joint loads as compared to barefoot gait in elderly women with knee OA, with the further advantage of providing external foot protection during gait.
- 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.
