Effects of foot structure type on core stability in university athletes
(Life, 2023) Moreno Barriga, Orlando Santiago; Romero Morales, Carlos; Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; Gómez Salgado, Juan; Caballero López, Julio; Vidal Valverde, Liz Carol; López López, Daniel
Purpose: This study assessed the impact of different types of medial foot arch on postural stability and core center of gravity muscle activity among collegiate athletes. Methods: The study sample included 103 university-level athletes across various sports (soccer, rugby, basketball, volleyball, field tennis, table tennis, karate, and cheerleading) from the College of Magdalena (Colombia) who exhibited distinct types of medial foot arch: 32 high, 35 low, and 36 neutral arches. Surface electromyography (sEMG) was employed to assess conduction velocity, magnitude values, latency, and fatigue in focal muscles including the spinal erector (SE), internal oblique (IO), external oblique (EO), and rectus abdominis (AR), while measurements of static and dynamic postural control were also considered. Post hoc analysis was performed with Bonferroni correction for all electromyographically measured muscle groups, as well as for measurements of static and dynamic postural stability. Pearson’s or Spearman’s correlation tests were used to compare the different types of feet. Results: There were no substantial differences observed between the distinct types of feet in terms of focal muscle activity, static stability, or dynamics. Even though the mean values indicated higher muscle activity and stability among those with high foot arches and lower values among those with low arches compared to the neutral foot type, this observed difference was deemed statistically insignificant. We also observed a positive correlation between internal oblique muscle activity and the average power of dynamic postural stability, which remained consistent across all foot types. Our findings indicate that static instability is directly correlated with dynamic instability in the anteroposterior direction, while a clear inverse relationship was established in the lateral direction upon examining the variable correlations. Conclusions: The presence of high or low foot arches did not significantly impact the activity of the muscles responsible for maintaining the body’s center of gravity or postural stability among university-level athletes. This suggests the existence of neuromuscular compensation mechanisms that attempt to restore balance and compensate for any changes in postural stability caused by varying foot types. Through targeted training that emphasizes activation of the internal oblique muscle, athletes may see improved postural stability. Our findings indicate that static stabilization exercises can also prove beneficial in improving dynamic stability in the anteroposterior plane, while a more dynamic approach may be required to improve dynamic stability in the lateral plane.

(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 María
Background: 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.
Gauze Application of Phenol for Matrixectomy
(Journal of the American Podiatry Association, 2008) Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; Sánchez Gómez, Rubén; Jules, Kevin T.
Phenol matrixectomy is commonly used to treat onychocryptosis. The podiatric medical community has been progressively improving the technique of phenol application to avoid cases of burns. We describe a modification that uses gauze to provide a safe way for the phenol to be applied and prevents skin lesions due to phenol burns. (J Am Podiatr Med Assoc 98(5): 418–421, 2008)

Clinical improvement in functional hallux limitus using a cut-out orthosis
(Prosthetics and orthotics international., 2016) Becerro De Bengoa Vallejo, Ricardo; Sánchez Gómez, Rubén; Losa Iglesias, Marta Elena
Background: Functional hallux limitus (FHL) has been implicated in the development of metatarsophalangeal joint osteoarthritis. Objectives: To determine whether cut-out orthosis treatment increases plantarflexion of the first metatarsal by increasing its declination angle. Study design: Cross-sectional study. Methods: A total of 46 female volunteers with an average age of 25.66 ± 5.70 years (range: 19–42 years) and FHL participated in the study. We assessed the degrees of movement of the first metatarsal and proximal phalanx bones at the first metatarsophalangeal joint without and while wearing the cut-out orthosis using the 3Space Fastrak® via sensors. Results: The movement of the plantarflexión declination angle of the first metatarsal bone was higher using the orthosis 29.84° ± 5.98° versus without orthosis 27.69° ± 5.91° (p < 0.031°). Use of sandals may have minimized the magnitude of movement changes associated with orthosis versus non-orthosis use. Conclusion: The cut-out orthosis demonstrated a beneficial effect on non-fixed first metatarsophalangeal and metatarsal cuneiform joints affected by FHL, significantly increasing the declination of the metatarsal angle. Furthermore, use of the cut-out orthosis significantly reduced adduction movement of the first metatarsal bone in the transverse plane. Clinical relevance The cut-out orthosis demonstrated a beneficial effect on non-fixed first metatarsophalangeal and metatarsal cuneiform joints affected by FHL, significantly increasing the declination of the metatarsal angle. Furthermore, use of the cut-out orthosis significantly reduced adduction movement of the first metatarsal bone in the transverse plane.

(Journal of the mechanical behavior of biomedical materials., 2018) Roca Dols, Andrea; Losa Iglesias, Marta Elena; Sánchez Gómez, Rubén; Becerro De Bengoa Vallejo, Ricardo; López López, Daniel; Rodríguez Sanz, David; Martínez Jiménez, Eva María; Calvo Lobo, César
The main objective of this research was to know how five different cushioning shoes may interfere in ground contact times of each gait phase of walking and running in contrast with barefoot condition. Thirty healthy sport recreational male runners participated in this study. They played over a treadmill wearing minimalist, Boost®, Ethyl-vinyl-acetate (EVA), Air® chamber and pronation-control cushioning shoes technologies and under barefoot condition, recording the last 30 s of walking and running at 5.17 km/h and 9 km/h respectively, while ground contact time duration of each phase of gait was recorded with circular standard pressure sensors located on plantar feet. During walking, the heel contact phase was the station that increased significantly ground contact times wearing all sole cushioning shoes (p < 0.001), excepting no sole shoes (minimalist), versus barefoot condition, being Air® chamber the model that showed the highest times of contact floor versus barefoot (0.28 ± 0.08 ms and 0.23 ± 0.12 ms vs 0.12 ± 0.07 ms and 0.18 ± 0.07 ms in heel contact during midstance phases, respectively). During running, propulsion phase was the station that showed the highest spent times on ground contact with the floor under all shoe conditions, even with minimalist, being again Air® chamber the model with higher significant times in two of three phases versus barefoot (0.11 ± 0.04 ms and 0.16 ± 0.11 ms vs 0.09 ± 0.03 ms and 0.10 ± 0.02 ms in midstance and propulsion phases respectively). Air chamber® was the model too with the most switch ratio to forefoot strike pattern (0.07 ± 0.10 ms to 0.16 ± 0.11 from heel contact to propulsion phase, respectively). In conclusion, a ground contact times increase using all cushioning running shoes compared with barefoot condition was shown in both walking and running test.

(JMIR mHealth and uHealth, 2020) Mazoteras Pardo, Victoria; Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; López López, Daniel; Calvo Lobo, César; Rodríguez Sanz, David; Martínez Jiménez, Eva María; Palomo López Patricia
Background: Hypertension is a global public health issue and is closely related to chronic kidney disorder (CKD). In people with CKD, strict monitoring of blood pressure is an important part of therapy. Objective: The aim of this research was to validate the iHealth Track blood pressure monitoring device for patients with CKD according to the European Society of Hypertension International Protocol 2010 (ESH-IP2). Methods: In total, 33 patients who received hemodialysis in Plasencia participated in the study. There were 9 successive measurements made, which conformed to the ESH-IP2. We calculated the differences between the standard reference device (Omron M3 Intellisense) and the test device (iHealth Track) for blood pressure and heart rate values. For 99 total comparisons of paired measurements, we classified differences into various categories (≤5 mmHg, ≤10 mmHg, and ≤15 mmHg for blood pressure; ≤3, ≤5, and ≤8 beats per minute for heart rate). Results: In 90 of 99 systolic blood pressure and 89 of 99 diastolic blood pressure comparisons between the devices, measurement differences were within 5 mmHg. In 81 of 99 heart rate comparisons between the devices, measurement differences were within 3 beats per minute. The mean differences between the test and reference standard measurements were 3.27 (SD 2.99) mmHg for systolic blood pressure, 3.59 (SD 4.55) mmHg for diastolic blood pressure, and 2.18 (SD 2.75) beats per minute for heart rate. We also observed that for both systolic and diastolic blood pressure, 31 of 33 participants had at least two of three comparisons between the devices with measurement differences less than 5 mmHg. For heart rate, 28 of 33 patients had at least two of three comparisons between the devices with measurement differences less than 3 beats per minute. Conclusions: To our knowledge, this is the first study to show that iHealth Track meets the requirements of the ESH-IP2 in patients with CKD. Therefore, the iHealth Track is suitable for use in renal patients.
Strengthening the relationship between intractable plantar keratosis and human papillomavirus
(Journal of Medical Virology, 2024) Alou Cervera, Luis; Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; Moreno, Juan; Sánchez Gómez, Rubén; González Hidalgo, Natalia; Sevillano Fernández, David
The aim of the study was to determine the presence of human papillomavirus (HPV) in patients with intractable plantar keratosis (IPK) by comparing the histopathological findings of biopsies. A prospective, observational, and concordance study was carried out. Three different specimens were taken from each IPK. A first punch was sent for histopathological examination, and a second punch and a superficial skin scraping were both sent for HPV polymerase chain reaction (PCR) and type determination. A total of 51 patients were included. From the histopathological examination, it was determined that 35 (68.6%) samples were diagnosed as warts and 16 (31.3%) as keratosis. However, the presence of HPV was confirmed by PCR in 49 (96.1%) and in 42 (82.4%) samples obtained by punch and superficial scraping, respectively. In the 49 PCR‐positive samples, the most common HPV types were HPV1, HPV2, HPV27, HPV57, and HPV65, accounting for 81.6% of the samples. In conclusion, this study demonstrates that HPV infection and IPK lesions are very closely related. Although we cannot confirm that HPV is the cause of the development of IPK, the high prevalence of HPV observed in these lesions calls for a change to the procedures for managing IPK.

(Journal of Medical Internet Research, 2020) Mazoteras Pardo, Victoria; Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; Martínez Jiménez, Eva María; Calvo Lobo, César; Romero Morales, Carlos; López López, Daniel; Palomo Lopez, Patricia
Background: Home blood pressure monitoring has many benefits, even more so, in populations prone to high blood pressure, such as persons with diabetes. Objective: The purpose of this research was to validate the QardioArm mobile device in a sample of individuals with noninsulin-dependent type 2 diabetes in accordance with the guidelines of the second International Protocol of the European Society of Hypertension. Methods: The sample consisted of 33 patients with type 2 diabetes. To evaluate the validity of QardioArm by comparing its data with that obtained with a digital sphygmomanometer (Omron M3 Intellisense), two nurses collected diastolic blood pressure, systolic blood pressure, and heart rate with both devices. Results: The analysis indicated that the test device QardioArm met all the validation requirements using a sample population with type 2 diabetes. Conclusions: This paper reports the first validation of QardioArm in a population of individuals with noninsulin-dependent type 2 diabetes. QardioArm for home monitoring of blood pressure and heart rate met the requirements of the second International Protocol of the European Society of Hypertension.
Electromyography comparison of the effects of various footwear in the activity patterns of the peroneus longus and brevis muscles
(Journal of the mechanical behavior of biomedical materials, 2018) Roca Dols, Andrea; Losa Iglesias, Marta Elena; Sánchez Gómez, Rubén; López López, Daniel; Becerro De Bengoa Vallejo, Ricardo; Calvo Lobo, César
Background Peroneus longus and brevis (PLB) disorders are commonly in people with lateral ligamentous instability, ankle pain, lateral hindfoot pain and structures of the proximal compartment of the lower legs and their muscle activity is believed to be influenced by different footwear types. The proposal of this research is to evaluate the effects of five types of footwear with respect to the barefoot condition and analyze the activity patterns of PLB muscles in healthy subjects during the gait cycle. Methods Thirty healthy subjects were recruited in a laboratory in this cross-sectional research design. While walking, electromyography (EMG) activity was measured from PLB via surface electrodes in six experimental conditions: 1) barefoot, 2) minimalist, 3) pronated control, 4) air chamber, 5) ethyl-vinyl-acetate (EVA) and 6) boost. These data were obtained and compared. Results The peroneus brevis showed significant reductions in the peak amplitude of the five footwear types (minimalist, pronation control, air chamber, EVA and boost) with respect to the barefoot condition in the propulsion phase of the gait cycle during walking (P = 0.034; P < 0.001; P < 0.001; P < 0.001; P = 0.006) and running (P = 0.004; P < 0.001; P = 0.001; P < 0.001; P = 0.001), respectively. Furthermore, peroneus longus showed significant reductions in the peak amplitude of these five footwear types with respect to the barefoot condition in the propulsion phase of the gait cycle during running (P = 0.005; P = 0.038; P = 0.019; P = 0.025; P = 0.021). Conclusion The EMG activity patterns of the PLB muscles may depend on the use of different types of sport shoes such as minimalist, pronation control, air chamber, EVA and boost footwear with respect the barefoot condition in different phases of the gait cycle during walking and running.
