Item Influence of an Upper Limb Isometric Task in Perceived and Performance Fatigability of Elderly Subjects: A Quasi-Experimental Study(Biology, 2022) Silva Migueis, Helena; Martínez Jiménez, Eva María; Casado Hernández, Israel; Dias, Adriano; Monteiro, Ana Júlia; Martins, Rodrigo B.; Romero-Morales, Carlos; López-López, Daniel; Gómez Salgado, JuanIsometric activity can be used as a strategy to improve health, fitness, and functional performance in the elderly population, but differences in fatigability may occur. This study aimed to understand fatigability behavior during an upper limb isometric task (ULIT) and the role of health status and physical activity in the fatigability of elderly participants. Thirty-two (32) elderly participants (72.5 ± 5.18 years) were instructed to perform ULIT. The Borg CR10 scale and task failure point (TTF) were used to measure perceived and performance fatigability. Self-reported measures were used to assess the quality of life and physical activity level. A significant relationship between perceived and performance fatigability was found only in the final phase of activity (p < 0.01). Significant correlations were found between perceived fatigability and the social functioning dimension (p < 0.05), and between performance fatigability (TTF) and BMI (p < 0.01), physical functioning (p < 0.01), and role functioning/physical (p < 0.05) dimensions. In conclusion, ULIT produces changes in fatigability of elderly people, which are positively related in the final stage of the activity. Changes in fatigability are negatively related to BMI. It is also negatively related to health, social functioning, physical functioning and role functioning/physical quality of life dimensions.Item Effectiveness of Custom Foot Insoles to Decrease Plantar Pressure: A Cross-over Randomized Trial Study(Healthcare, 2022) Casado Hernández, Israel; Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; Cosín Matamoros, Julia María; Calvo Lobo, César; Rodríguez Sanz, David; López López, Daniel; Martínez Jiménez, Eva MaríaBackground: Harderness insoles decrease plantar pressure and reduce the foot injury incidence in sport. The purpose of our study was to analyze the plantar pressure variation in moto riders after riding in a real speed circuit with a custom foot 520 Shore EVA insole. Methods: A crossover randomized trial study was performed (consent no. #050520165316). Riders were assessed by an expert motorsport senior podiatry. The participants’ mean age was 35 ± 3.29. Participants completed a 20 min training riding with their own motorcycle in a real speed circuit. Plantar pressures were registered with a baropodometric platform evaluating an Ethyl Vinyl Acetate custom foot insole (CFI) manufactured with 3 mm thickness and 52° Shore A hardness. The Plantar pressures were registered before riding, after riding without EVA insole, and after riding with EVA insole. Results: Total Plantar pressures in right and left foot, and total surface area decrease after riding with EVA insoles. Conclusion: The use of an EVA insole with 520 shore A hardness riding on a motorcycle in speed circuit decreased the total plantar pressures and surface areas values.Item Sex Differences in the Footprint Analysis During the Entire Gait Cycle in a Functional Equinus Condition: Novel Cross Sectional Research(Applied Sciences, 2019) Losa-Iglesias, Marta Elena; Díaz-Velázquez, José Ignacio; Casado Hernández, Israel; Calvo Lobo, César; López-López, Daniel; Rodríguez Sanz, David; Martínez Jiménez, Eva María; Becerro De Bengoa Vallejo, RicardoSome studies suggest that gender is related to gait. Females show significantly higher ankle motion and vertical ground reaction forces. Males have significantly larger plantar contact surface areas in all regions of the foot than females in most, but not all, prior studies. However, there is no research on sex differences in a functional equinus condition. In this study, 119 individuals, including 59 females (29.7 ± 5.15 years, 58.74 ± 6.66 kg, 163.65 ± 5.58 cm) and 60 males (31.22 ± 6.06 years, 75.67 ± 9.81 kg, 177.10 ± 6.16 cm), with a functional equinus condition walked onto a pressure platform. In two separate testing sessions, five trials of each foot were conducted for the first, second, and third steps. We measured the contact surface areas for each of the three phases of the stance phase. We computed the intraclass correlation coefficient and standard error of the mean to assess the reliability. We found significantly greater contact surface areas in males than females in the first, second, and third steps in all phases of the stance phase: heel strike, mid-stance, and take-off. This is important information for the design of footwear and orthotics and gender knowledge. In a functional equinus condition, males have registered greater contact surface areas than females in all phases of the dynamic footprint of the stance phase.- Project number: PIMCD73/23-24
Item Utilización de la metodología de Simulación clínica en la entrevista clínica para estudiantes de estudiantes de ciencias de la salud.(2024) Martínez Jiménez, Eva María; Becerro De Bengoa Vallejo, Ricardo; Zaragoza García, Ignacio; Posada Moreno, María Paloma; Alcolea Palafox, Mauricio; Calvo Lobo, César; Pedraza Velasco, María Lourdes De; Pérez Boal, Eduardo; Casado Hernández, Israel; Soriano Medrano, Alfredo; Rodríguez Sanz, David; Muñoz Sánchez, José Luis; Rodríguez Sancho María José; Martínez Jiménez, Eva María Item Upper-limb kinematic behavior and performance fatigability of elderly participants performing an isometric task: a quasi-experimental study(Bioengineering, 2023) Silva Migueis, Helena; Martínez Jiménez, Eva María; Casado Hernández, Israel; Dias, Adriano; Monteiro, Ana Júlia; Martins, Rodrigo B.; Bernardes, João Marcos; López López, Daniel; Gómez Salgado, JuanUpper-limb position-sustained tasks (ULPSIT) are involved in several activities of daily living and are associated with high metabolic and ventilatory demand and fatigue. In older people, this can be critical to the performance of daily living activities, even in the absence of a disability. Objectives: To understand the ULPSIT effects on upper-limb (UL) kinetics and performance fatigability in the elderly. Methods: Thirty-one (31) elderly participants (72.61 ± 5.23 years) performed an ULPSIT. The UL average acceleration (AA) and performance fatigability were measured using an inertial measurement unit (IMU) and time-to-task failure (TTF). Results: The findings showed significant changes in AA in the X- and Z-axes (p < 0.05). AA differences in women started earlier in the baseline cutoff in the X-axis, and in men, started earlier between cutoffs in the Z-axis. TTF was positively related to AA in men until 60% TTF. Conclusions: ULPSIT produced changes in AA behavior, indicative of movement of the UL in the sagittal plane. AA behavior is sex related and suggests higher performance fatigability in women. Performance fatigability was positively related to AA only in men, where movement adjustments occurred in an early phase, though with increased activity time.Item Electromyographic Evaluation of the Impacts of Different Insoles in the Activity Patterns of the Lower Limb Muscles during Sport Motorcycling: A Cross-Over Trial(Sensors, 2019) Casado Hernández, Israel; Becerro De Bengoa Vallejo, Ricardo; Losa-Iglesias, Marta Elena; López-López, Daniel; Rodríguez Sanz, David; Martínez Jiménez, Eva María; Calvo-Lobo, CésarCustomized foot insoles (CFI) have been recognized to reduce the prevalence of foot disorders in sport. The aim of this study was to evaluate the effect of four types of CFI on the activity patterns of the lower limb muscles (LLM) in healthy people during sport motorcycling. Methods: This was a cross-over trial (NCT03734133. Participants were recruited from an outpatient foot specialist clinic. Their mean age was 33 ± 5.14 years. While participants were sport motorcycling in a simulator, the electromyography (EMG) function was registered for LLM via surface electrodes. Participants completed separate tests while wearing one of four types of CFI: (1) only polypropylene (58◦ Shore D), (2) selective aluminum (60 HB Brinell hardness) in metatarsal and first hallux areas and polypropylene elsewhere (58◦ Shore D), (3) ethylene vinyl acetate (EVA) (52◦ Shore A), and (4) standard EVA (25◦ Shore A) as the control. Results: The activity patterns of the LLM while sport motorcycling showed significantly lower peak amplitude for the selective aluminum CFI than the other types of CFI. Conclusion: EMG amplitude peaks for several LLM were smaller for the hardest CFI (selective aluminum 60 HB Brinell hardness) than the other CFIs (polypropylene 58◦ Shore D, EVA 52◦ Shore A, and standard EVA 25◦ Shore A), except for the fibularis longus in right curves that is increased when the knee touches the road increasing the stability.Item The Effectiveness of Hard Insoles for Plantar Pressure in Cycling: A Crossover Study(Bioengineering, 2023) Casado Hernández, Israel; Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; Soriano Medrano, Alfredo; López López, Daniel; Navarro Flores, Emmanuel; Pérez Boal, Eduardo; Martínez Jiménez, Eva MaríaBackground: Hard insoles have been proposed to decrease plantar pressure and prevent foot pain and paresthesia due to repetitive loading. The aim of this research was to analyze the effect of three different hard insoles in cycling on healthy subjects. Methods: A crossover randomized trial was carried out. The mean age of the subjects was 35 ± 3.19 years, and all of them were men. While the subjects were cycling on a stationary bicycle, their plantar pressure was recorded with nine in-shoe sensors placed in nine specific foot areas to test a standard ethylene-vinyl-acetate 52° Shore A hardness insole, a polypropylene 58° Shore D insole, and a polypropylene 580 Shore D insole with selective aluminum 60 HB Brinell hardness in the metatarsal head and hallux. Results: The maximum plantar pressure decreased significantly with the polypropylene insole containing selective aluminum in the metatarsal head and hallux areas. The maximum plantar data of the polypropylene aluminum insole in the M2 area (5.56 kgF/cm2), fifth metatarsal styloid process (6.48 kgF/cm2), M3-M4 area (4.97 kgF/cm2), and hallux (8.91 kgF/cm2) were of particular interest compared to the other insoles. Conclusions: The use of insoles made of polypropylene with aluminum in the metatarsal head and hallux areas decreases the maximum plantar pressure in cycling compared to standard EVA and polypropylene insoles.Item Influence of Different Hardness Custom Foot Insoles in the Electromyography Activity Patterns of the Thigh and Hip Muscles during Motorcycling Sport: A Crossover Study(Sensors, 2020) Casado Hernández, Israel; Becerro De Bengoa Vallejo, Ricardo; Losa-Iglesias, Marta Elena; Martínez Jiménez, Eva María; López-López, Daniel; Mazoteras Pardo, Victoria; Romero-Morales, Carlos; Calvo Lobo, CésarNowadays, the use of insoles in sport practice have been recognized to decrease the foot and lower limb injury patterns. The aim of this study was to analyse the effect of four types of hardness insoles (HI) in the activity patterns of the hip and thigh muscles (HTM) in motoriders during motorcycling sport. The study was a crossover trial. Subjects were elite motoriders. The mean age was 33 ± 5.14 years. Electromyography (EMG) of hip and thigh muscles (HTM) data was registered via surface while subjects were riding on an elite motorcycle simulator. Subjects had to complete different tests with randomly hardest insoles (HI): 1: only polypropylene (58◦ D Shore); 2: Polypropylene (58◦ D Shore) with selective aluminium in hallux and metatarsal heads (60 HB Brinell hardness); 3: Ethylene vinyl acetate (EVA) (52◦ A Shore); and finally, 4: Ordinary EVA (25◦ A Shore) as the control. EMG patterns of the HTM, riding on an elite motorcycle simulator, showed the lowest peak amplitude with the insoles with polypropylene and selective aluminium. Using the hardest insoles in our study (selective aluminium) the EMG amplitude peaks decreased in all HTM.Item Orthopaedic Simulation of a Morton’s Extension to Test the Effect on Plantar Pressures of Each Metatarsal Head in Patients without Deformity: A Pre-Post-Test Study(Diagnostics, 2023) Sánchez Serena, Anna; Losa Iglesias, Marta Elena; Becerro De Bengoa Vallejo, Ricardo; Morales Ponce, Ángel; Soriano Medrano, Alfredo; Pérez Boal, Eduardo; Grande del Arco, Jessica; Casado Hernández, Israel; Martínez Jiménez, Eva MaríaBackground: the area beneath the metatarsal heads is a common location of foot pain, which is often associated with high plantar pressures. The aim of this study was to determine the effect of the application of a Morton’s extension on the pressure in the metatarsal bones of the foot using a pressure platform. Methods: twenty-five subjects without musculoskeletal pathology were selected for this study, and an experiment was conducted with them as the subjects, before and after application of a Morton’s extension. The foot regions were divided into the forefoot (transversely subdivided into six areas corresponding to the first, second, third, fourth, and fifth metatarsal heads, and the hallux), midfoot, and rearfoot, and then the maximum and average pressures exerted at each region were measured before and after placing a Morton’s extension. Main findings: we found a pressure reduction, with a p-value less than (p < 0.05), in the head of the second and third metatarsals in statics and dynamics. Conclusions: we can conclude that the Morton’s extension produces a variation in plantar pressures on the lesser metatarsals. The application of a Morton’s extension may be beneficial for the management of forefoot pathology. This study will help clinicians consider various tools to treat forefoot disorders.
