“…En cuanto a la marcha prolongada, existen intervenciones con protocolos diferentes, con una duración corta y un descanso más largo para evitar la modificación del patrón de la marcha por el cansancio (Khoury-Mireb et al, 2019;Pérez-Soriano et al, 2019). En este caso, no se han encontrado diferencias significativas entre los diferentes momentos, lo que puede atribuirse al hecho de que, aunque el protocolo es más largo comparando con los estudios anteriormente nombrados, no lo ha sido suficiente como para observar la aparición del cansancio (Khoury-Mireb et al, 2019), al menos para una velocidad de 1.44 m/s.…”

Actualmente, están disponibles en el mercado nuevos modelos de calzado deportivo, como el calzado inestable. Sin embargo, todavía existe una falta de evidencia respecto a los cambios que este tipo de calzado puede producir en la biomecánica de la marcha. Así pues, el objetivo de esta investigación fue analizar los efectos agudos del calzado inestable sobre los impactos de aceleración, así como también sobre la variación de temperatura superficial plantar. Seis deportistas (estudiantes físicamente activos, edad 28±8 años, altura 1.73±0.05 m, masa corporal 68.7±6.7 kg, talla de pie 41±1.6 cm) participaron voluntariamente en el estudio. Las características de la pisada se obtuvieron mediante el test Foot Posture Index. La prueba de marcha se llevó a cabo sobre tapiz rodante (10 minutos a 1.44 m/s) bajo dos condiciones de calzado: zapatillas estables y zapatillas inestables. Se analizaron los impactos de aceleración (en tibia y cabeza), y la temperatura superficial plantar (en antepié, mediopié y retropié) en diferentes momentos de la prueba. Los resultados no mostraron diferencias significativas entre ambos tipos de zapatillas en las variables de acelerometría analizadas en ninguno de los momentos de registro. Sin embargo, sí se encontraron diferencias significativas entre ambos calzados (estable=1.40ºC, inestable=3.10ºC, p=0.004) en la variación de temperatura plantar del mediopié en ΔTPost5 (diferencia entre antes del inicio de la prueba y 5 minutos después de finalizarla). En conclusión, las zapatillas inestables parecen no producir ningún beneficio adicional al calzado tradicional para el deportista durante la marcha. Palabras clave: zapatillas, marcha, biomecánica, acelerometría, termografía. Abstract. Nowadays, new models of sports footwear are available on the market, such as unstable shoes. However, there is still a lack of evidence regarding the changes that this type of footwear can produce on gait biomechanics. Therefore, the aim of this research was to analyze the acute effects of unstable shoes on acceleration impacts, as well as on plantar surface temperature variation. Six athletes (physically active college students, age 28±8 years, height 1.73±0.05 m, body mass 68.7±6.7 kg, shoe size 41±1.6 cm) voluntarily participated in the study. Gait characteristics were obtained by means of the Foot Posture Index test. The walking test was performed on a treadmill (10 minutes at 1.44 m/s) under two footwear conditions: stable shoes and unstable shoes. Acceleration impacts (tibia and head), and plantar surface temperature (forefoot, midfoot and rearfoot) were analysed at different moments during the test. The results showed no significant differences between the two types of shoes in the accelerometry variables analyzed at any of the recording times. However, significant differences were found between both shoes (stable=1.40ºC, unstable=3.10ºC, p=0.004) in the variation of midfoot plantar temperature at ΔTPost5 (difference between before the start of the test and 5 minutes after the end of the test). In conclusion, unstable shoes do not seem to produce any additional benefit to traditional shoes for the athlete during walking. Keywords: sport shoes, gait, biomechanics, accelerometry, thermography.

“…In order to investigate the effect of footwear conditions on lumbosacral compression force, EMG activities of main trunk extensor and flexor muscles were recorded 3 . EMG activities of left/right longissimus (LG-L/LG-R), iliocostalis (IC-L/IC-R), multifidus (MF-L/MF-R), and rectus abdominis (RA-L/RA-R) muscles were collected using an eight-channel wireless system at a sampling rate of 1200 Hz (Myon 320, Switzerland).…”

“…However, long-term use of rocker-sole shoes does not appear to influence postural stability in people with chronic low back pain. Using unstable shoes has also been found to cause an immediate decrease in the variability of frontal-plane foot CoP offset, transverse-plane ankle moment, and frontal-plane shoulder angle in comparison to stable shoes 3 . However, the transverse-plane spine angle variability has been reported to increase during walking in the unstable configuration.…”

The present study examined the effects of auxetic shoes on the biomechanics of the spine, as compared to barefoot and conventional shoe conditions, during gait and drop vertical jump (DVJ) activities using a combined in vivo and musculoskeletal modeling approach. Motion and force-plate data as well as electromyographic (EMG) activities of select trunk muscles of 11 individuals were collected during foregoing activities. In DVJ activity, two main phases of first landing (FL) and second landing (SL) were studied. In the FL phase of DVJ noticeable alternations were observed when auxetic shoes were used. That is, compared to the conventional footwear condition, smaller EMG activities in extensor muscles (by ~ 16–29%, p < 0.001), smaller anterior–posterior (AP) distance between the center of pressure of ground reaction force and heel (by ~ 19%, p = 0.002), generally larger maximal hip, knee, and ankle flexion angles (p < 0.005) and finally smaller maximal L5-S1 compression force and maximal external moment (by ~ 12 and 8%, respectively, p < 0.001) were obtained by wearing auxetic shoes. Our results, therefore, indicate that using auxetic shoes can reduce load on the lumbar spine during high-demanding activities such as vertical jump and thus may decrease the musculoskeletal risk of injuries during these activities.

“…A home-based biomechanical intervention (AposHealth ® , New York, US) that includes a unique foot-worn device to manipulate the center of pressure (COP) and train neuromuscular control and a home-based treatment plan has been in use for a few years. The therapy addresses the underlying biomechanical aspects of knee OA (Haim et al Solomonow-Avnon, Herman, and Wolf 2019;Khoury-Mireb et al 2019;Debbi, Wolf, and Haim 2012;Goryachev, Debbi, Haim, Rozen, et al 2011) (i.e., reducing loads by shifting the center of pressure and neuromuscular training), while reducing pain and improving function (Goryachev, Debbi, Haim, Rozen, et al 2011;Debbi et al 2015;Haim et al 2012;Bar-Ziv et al 2010Drexler et al 2012;Lador et al 2013;Elbaz et al 2010Elbaz et al , 2011Lubovsky et al 2015;Herman et al 2018;Reichenbach et al 2020;Miles and Greene 2020;Barzilay et al 2015;Elbaz et al 2009;Lee et al 2018;Elbaz et al 2013;Haim et al 2013;Atoun et al 2016;Elbaz, Debbi, et al 2014;Yaari et al 2015;Debbi et al 2019;Solomonow-Avnon et al 2017;Segal et al 2013;Tenenbaum et al 2017) (Figure 2). Patients are instructed to wear a personally calibrated device for 30-60 minutes a day while performing their daily activities at home or work (usage time may increase gradually, depending on progress and symptoms).…”

Osteoarthritis (OA) is the second most frequent chronic musculoskeletal (MSK) condition after low back pain and a leading cause of disability in the elderly. The number of people living with disability will continue to rise with the aging of the population. Moreover, the rapid increase in rates of surgical intervention, i.e. Total knee replacement (TKR) and revision TKRs, is expected to place an immense burden on the health care system and society. There is a call for better rehabilitation, new interventions, and disease management for patients with knee OA. The purpose of this article is to review the biomechanics of knee OA and biomechanical interventions and to summarize the current literature on a non-invasive, home-based biomechanical treatment for patients with knee OA. The evidence suggests an improvement in symptoms and biomechanical indicators after using the home-based biomechanical intervention. In the presence of value-based payment to improve efficiency and effectiveness in delivering medical care, these results are promising.
