The Biomechanics Research and Innovation Challenge: Development, Implementation, Uptake, and Reflections on the Inaugural Program.

Biomechanics as a discipline is ideally placed to increase awareness and participation of girls and women in science, technology, engineering, and mathematics. A nationwide Biomechanics and Research Innovation Challenge (BRInC) centered on mentoring and role modeling was developed to engage high school girls (mentees) and early-mid-career women (mentors) in the field of biomechanics through the completion of a 100-day research and/or innovation project. This manuscript describes the development, implementation, and uptake of the inaugural BRInC program and synthesizes the research and innovation projects undertaken, providing a framework for adoption of this program within the global biomechanics community. Eighty-seven high school girls in years 9 and 10 (age range: 14-16 y) were mentored in teams (n = 17) by women in biomechanics (n = 24). Using a design thinking approach, teams generated solutions to biomechanics-based problem(s)/research question(s). Eight key reflections on program strengths, as well as areas for improvement and planned changes for future iterations of the BRInC program, are outlined. These key reflections highlight the innovation, impact, and scalability of the program; the importance of a program framework and effective communication tools; and implementation of strategies to sustain the program as well as the importance of diversity and building a sense of community.

Narrative histories of physiotherapy in Colombia, Ecuador, and Argentina.

BACKGROUND: The history of physiotherapy in Latin America has received little attention thus far in the English-speaking literature. In this paper, we draw on narratives from activists, educators, and professional leaders who have been instrumental in shaping the development of physiotherapy in Argentina, Colombia, and Ecuador. Physiotherapists in the Latin American countries faced many similar challenges, including developing physiotherapy in the shadow of medicine, overcoming conservative attitudes toward women professionals, and frequent social upheaval. AIMS: The paper explores the disputed story of physiotherapy's origins in the polio epidemics, the influence of Swedish remedial gymnastics, and the educational colonialism of North American and European educators. We examine some of the effects of social unrest and trauma, military rule, and economic instability on the professions attempts to establish itself in the face of competition from other professions allied to medicine. And we consider the efforts taken to establish the profession's autonomy and its shifting relationship with the state. METHODS: We employed two different methods for data collection to explore aspects of physiotherapy's history in Latin America from a political and socio-cultural context: 1) A reconstruction of memories from activist physiotherapists in Colombia, Ecuador, and Argentina, who have seen, lived, and promoted the development of physiotherapy in their own countries, gleaned from in-depth interviews; and 2) Analysis of secondary sources. Data were analyzed following the method described by Maynes, Pierce, and Laslett (2008), exploring personal narratives. Textual data were analyzed using documentary research (Prior, 2003) using thematic analysis, to inductively discover, and describe relevant themes about the two main guiding study questions. A constant comparative method as outlined by Boeije (2002) was used to form categories, establish boundaries, and discerning conceptual similarities between participants' narrative. RESULTS: Five physiotherapists were interviewed. One from Colombia, two from Argentina and two from Ecuador. Three main themes were identified: 'A Female Profession?', 'training and education', and 'Present Day in Argentina, Ecuador, and Colombia'. Tensions between the interests of the State, professionals, patients, cultures, urban and rural services, and practices are prevalent throughout physiotherapy in Argentina, Colombia, and Ecuador. Operating within these tensions is very much the reality for physiotherapists in Latin America today. CONCLUSION: Multiple histories emerge from the research, opening up a space for a more nuanced, polyphonic reading of physiotherapy in Colombia, Ecuador, and Argentina than has been heard to date.

A Wearable Biofeedback Device to Increase Gait Swing Time Could Have Positive Effects on Gait among Older Adults.

Older adults walk with a shorter stride length, reduced hip range of motion (ROM) and higher cadence. These are signs of reductions in walking ability. This study investigated whether using a wireless smart insole system that monitored and provided biofeedback to encourage an extension of swing time could increase stride length and hip flexion, while reducing the cadence. Seven older adults were tested in this study, with and without the biofeedback device, in an outdoor environment. Gait analysis was performed by using GaitRite system and Xsens MVN. Repeated measures analysis demonstrated that with biofeedback, the swing time increased by 6.45%, stride length by 4.52% and hip flexion by 14.73%, with statistical significance. It also decreased the cadence significantly by 5.5%. This study has demonstrated that this smart insole system modified positively the studied gait parameters in older adults and has the potential to improve their walking ability.

Effects of Wearable Devices with Biofeedback on Biomechanical Performance of Running-A Systematic Review.

This present review includes a systematic search for peer-reviewed articles published between March 2009 and March 2020 that evaluated the effects of wearable devices with biofeedback on the biomechanics of running. The included articles did not focus on physiological and metabolic metrics. Articles with patients, animals, orthoses, exoskeletons and virtual reality were not included. Following the PRISMA guidelines, 417 articles were first identified, and nineteen were selected following the removal of duplicates and articles which did not meet the inclusion criteria. Most reviewed articles reported a significant reduction in positive peak acceleration, which was found to be related to tibial stress fractures in running. Some previous studies provided biofeedback aiming to increase stride frequencies. They produced some positive effects on running, as they reduced vertical load in knee and ankle joints and vertical displacement of the body and increased knee flexion. Some other parameters, including contact ground time and speed, were fed back by wearable devices for running. Such devices reduced running time and increased swing phase time. This article reviews challenges in this area and suggests future studies can evaluate the long-term effects in running biomechanics produced by wearable devices with biofeedback.
