Foot Pain and Disability in Women with Rheumatoid Arthritis, Ehlers-Danlos Syndrome and Systemic Lupus Erythematosus: Relationship with Quality of Life.

The aim of this work was to investigate the relationship foot pain and foot disability have with HRQoL in groups of women with RA, SLE and EDS, in comparison with a control group. A cross-sectional study was carried out with females with one of these conditions and a control group. The SF-12 questionnaire was used to collect data about quality of life. The type of foot was classified according to the footprint and the foot posture index. A total of 156 patients and 47 controls participated in the study (N = 203). Neither pain nor foot posture were different between groups. The physical and mental components of SF-12 were worse in rheumatoid arthritis and Ehlers-Danlos syndrome patients, and the physical component was worse in systemic lupus erythematosus patients, compared to controls. A significant difference was also observed in the mental component between systemic lupus erythematosus and Ehlers-Danlos syndrome patients, the latter having the lowest values among the groups. We can conclude that women with rheumatoid arthritis, Ehlers-Danlos syndrome, systemic lupus erythematosus and foot pain perceive a worse quality of life. There are no significant changes in foot posture. Pain and health-related quality of life are independent of foot posture.

How susceptible are our Achilles Tendons? Sonoanatomical assessment. A cross-sectional study.

OBJECTIVE: the aim of this study is to observe whether there are ultrasound changes between men and women in the Achilles tendon at rest, at maximum passive force is applied and during walking. MATERIAL AND METHODS: it was a cross-sectional study involving 27 healthy young participants recruited as volunteers between April to July 2022. A variety of data was recorded: (age, Body Mass Index, sex, smoking, current injury status, allergies, medications, previous surgeries, type of sport, and number of weekly workouts) and ultrasound measurements at rest and at passive force (Cross Sectional Area Achilles Tendon length, tendon thickness, Cross Sectional Area and pennation angle of the soleus muscle to the Achilles Tendon). RESULTS: women demonstrated a statistically significant lower proximal and median thickness both at rest (4.5 vs 5.1 mm with p < 0.001 for proximal thickness; 4.4 vs 5.3 mm with p < 0.001 for median thickness) as well as during maximum eccentric contraction (4.3 vs 4.8 mm with p=<0.001 for proximal thickness; 4.1 vs 4.8 mm with p < 0.001 for median thickness). CONCLUSION: there are significant sonoanatomical differences in vivo Achilles tendon between men and women.

Effectiveness of the Ponseti Method in the Treatment of Clubfoot: A Systematic Review.

Clubfoot is a common congenital deformity of the lower limbs. It should be treated as soon as possible so that its correction is more easily achieved. The objective of this systematic review was to assess the effectiveness of the Ponseti method in the treatment of clubfoot. A bibliographic search was carried out in different databases, including PubMed and SciELO. Filters such as full text and randomized controlled trial were selected to find those articles that best matched our search. Among the results, we selected the ones that interested us, and the rest were discarded, either because they did not meet the requirements for our work or because they were repeated. In total, we collected 19 articles, but after using the critical evaluation instrument CASPe, 7 of them were eliminated, leaving us with a total of 12 articles for our systematic review. After analyzing the results obtained in the selected articles, we concluded that the Ponseti method is effective in the treatment of clubfoot, presenting a high success rate.

Effectiveness of custom-made functional foot orthoses versus flat cushioning insoles on pain in patients with systemic lupus erythematosus.

OBJECTIVE: To determine the effect of foot orthoses on pain, disability and foot functionality in patients with Systemic Lupus Erythematosus. DESIGN: Randomized clinical trial. SETTING: University Podiatric Clinical Area. SUBJECTS: Patients with systemic lupus erythematosus. INTERVENTIONS: Patients were randomly assigned to either group A, which received custom-made functional foot orthoses, or group B, which received flat cushioning insoles, for three months. MAIN MEASURES: The primary outcome was foot pain, measured by 11-point numeric pain rating scale. Foot functionality and foot-related disability were evaluated using the foot function index, the Manchester foot pain and disability, at the beginning and at days 90. RESULTS: Sixty-six participants (age 47.3 ± 11.9 years) suffering from foot pain, received either the custom-made foot orthoses (N = 33) or the flat cushioning insoles (N = 33). For the analysis of the data, only participants who had finished the follow-up period (90 days) were included. None statistically significant difference between groups were found. In group A, all variables showed statistically significant differences when comparing the initial and final measurements. Pain showed 6.8 ± 1.6 and 4.2 ± 2.9 in group A, at baseline and at 90 days, respectively, group B showed 6.5 ± 1.5 and 4.7 ± 3.0 at baseline and at 90 days, respectively. CONCLUSION: Both groups showed a reduction in foot pain. This study suggests that not only controlling the foot function, but providing cushioning to the foot, may have positive effects to manage foot pain in patients with systemic lupus erythematosus.

Morfología y función del pie en pacientes con ciática. Un estudio descriptivo transversal / Morphology and function of the foot in patients with sciatica. A cross-sectional study

Objetivos: El objetivo de este trabajo es comparar las características articulares de los pies de pacientes con ciática, con las de los pies de personas sin esta patología. Pacientes y métodos: Se trata de un estudio descriptivo transversal. Se incluyeron 20 pacientes con ciática y 20 pacientes sin esta patología emparejados por edad y sexo. Se cuantificó el dolor del pie mediante la Numeric Pain Rating Scale 11 y se midió la movilidad de las articulaciones del tobillo, subastragalina, antepié, primer radio y primer dedo. Se clasificó el tipo de pie mediante el Foot Posture Index, y se cuantificó la discapacidad relacionada con el dolor del pie mediante el cuestionario Manchester Foot Pain and Disability Index. Se compararon estas variables entre los dos grupos de participantes (con ciática y sin ciática). Resultados: Se observó un menor rango de movimiento de pronación subastragalina, así como mayor dolor en el pie y mayor discapacidad relacionada con el dolor en el pie, en los participantes con ciática en comparación con los del grupo control. La extensión del hallux también fue significativamente menor en los sujetos con ciática, aunque solo en el pie izquierdo. Además, la fuerza muscular en estos pacientes fue menor que en los que no tenían ciática. Los participantes de ambos grupos presentaron valores de flexión dorsal del tobillo por debajo de la normalidad. Conclusiones: Los participantes con ciática presentaron ciertas diferencias articulares y musculares con respecto al grupo control, aunque no se puede establecer una relación causa-efecto debido al diseño del estudio (AU)

Objectives: The objective of this work is to compare the joint characteristics of the feet of patients with sciatica, with those of people without this pathology. Patients and methods: This is a cross-sectional descriptive study. Twenty patients with sciatica and 20 patients without this pathology were included. Foot pain was quantified using the Numeric Pain Rating Scale 11, and mobility of the ankle, subtalar, forefoot, first ray, and hallux joints were measured. Foot type was classified using the Foot Posture Index, and disability related to foot pain was quantified using the Manchester Foot Pain and Disability Index questionnaire. These variables were compared between the two groups (participants with and without sciatica). Results: Less subtalar pronation range of motion, as well as greater foot pain and greater foot pain-related disability, were observed in participants with sciatica compared with those in the control group. Hallux dorsalflexion was also significantly less in subjects with sciatica, although only in the left foot. Muscle strength in these patients was lower than in those without sciatica. Participants in both groups presented values of ankle dorsiflexion below normal.Conclusions: The participants with sciatica presented certain joint and muscle differences with respect to the control group, although a cause-effect relationship cannot be established due to the study design (AU)

Influence of Health Education on Podiatric Knowledge, Self-care, and Conditions in Adults With Diabetes Mellitus: A Systematic Review.

OBJECTIVE: To determine if health education has an influence on podiatric knowledge, self-care, and conditions in adults with diabetes mellitus. DATA SOURCES: The authors conducted a literature search for Spanish-, English-, and Portuguese-language publications using PubMed, Scopus, Dialnet, and CUIDEN. STUDY SELECTION: Selected keywords related to diabetes, health education, (diabetic) foot, and self-care were searched, and the titles, abstracts, and relevant full-text articles were screened. Thirteen studies were selected with a total of 1,296 participants. Four were randomized controlled trials, and nine were quasi-experimental studies. DATA EXTRACTION: Data pertaining to preventive intervention and study outcomes were extracted. DATA SYNTHESIS: The preventive interventions used varied from traditional educational workshops and one-on-one patient education to new technological strategies. Three different outcomes were evaluated in each study: podiatric knowledge (n = 4), foot self-care (n = 13), and foot problems (n = 2). CONCLUSIONS: Health education interventions increase podiatric self-care in adults with diabetes mellitus. These interventions appear to contribute positively to foot health and podiatric knowledge.

Use of Plantar Pressure Sensors to Take Weight-Bearing Foot Casts.

Techniques of taking casts mainly rely not on the objectivity of the procedure, but on the experience and skill of the technician. The aim of this study was to demonstrate the efficiency of a technique of taking standing foot casts controlled via pressure sensors. In this way, we mean to objectivize the degree of correction. The study was carried out through 150 procedures on 50 feet of 29 patients. The value of the "Heel Symmetry Index" was calculated on three casts in three different situations of the same foot: A first cast in which the subject did not control the position of his/her foot; a second cast where manipulations corrected the foot's pronator position; and a third cast with pressure sensors placed in the subject's heel. This enabled the control and quantification of the pressure during the manipulation when taking the cast. The comparison of the "Heel Symmetry Index" in the different groups showed significant p-values of 0.05. Conclusion: The technique of taking casts controlled by pressure sensors achieved more equilibrated casts with a better symmetry index of the heel's outline.

Relationship of Body Mass Index and Footprint Morphology to the Actual Height of the Medial Longitudinal Arch of the Foot.

The medial longitudinal arch height of the foot is linked to individual characteristics such as sex and body mass index, and these characteristics have been shown to be associated with conditions such as flat feet. In this cross-sectional descriptive study, we examined the medial longitudinal arch morphology in an adult population to determine if there are differences related to sex and body mass index, and values were obtained for the foot posture index. Normalized anthropometric measurements and arch indices were calculated from footprints. Groups, defined by sex and body mass index, were compared, and the correlations between body mass index and the variables were determined. In the population studied (266 women and 177 men), significant differences between men and women for the foot posture index and normalized arch measurements were found. Analysis of the variables related to body mass index indicated there were significant differences in arch indices. Significant differences and positive correlations were also found between the arch index and body mass index for the left and right feet among the men and women studied. The results obtained allow us to reflect on and analyze whether the medial longitudinal arch morphology classification methods used in the clinical and research setting are adequate or whether the influence of factors such as body mass index can generate confusion.

Foot Pain and Morphofunctional Foot Disorders in Patients with Rheumatoid Arthritis: A Multicenter Cross-Sectional Study.

Foot problems are highly prevalent in people with rheumatoid arthritis. This study aims to explore the foot morphology, pain and function in rheumatoid arthritis patients and the relation with the time of disease debut. A cross-sectional study was designed. Footprint, the Foot Posture Index, the hallux valgus prevalence, foot pain and function in 66 rheumatoid arthritis patients and the association with time since diagnosis, were recorded. The Foot Function Index, the Manchester Foot Pain and Disability Index, the Visual Analogic Scale, and the Manchester Scale for hallux valgus were administered and analyzed in two groups, with less and more than 10 years of diagnosis of the disease. A high prevalence of pronated (right 36.8% and left 38.6%) and highly pronated (right 15.8% and left 15.8%) feet was observed, as well as an elevated percentage of low arched footprints (right 68.4 and left 66.7%) and hallux valgus (right 59.6% and left 54.4%). Hallux valgus prevalence, toe deformities and Foot Function Index (Functional limitation) factors were significantly associated with the time since RA diagnosed adjusted for the other factors. The adjusted odds ratio of Hallux valgus prevalence was 4.9 (1.2-19.7). In addition, the foot function was diminished, and foot pain was present in most participants. In conclusion, rheumatoid arthritis patients' feet showed altered morphology and function, and with longer rheumatoid arthritis history, metatarsophalangical stability and foot function, but not pain and global foot posture, were likely to deteriorate.

Study of the Distortion of the Indirect Angular Measurements of the Calcaneus Due to Perspective: In Vitro Testing.

The study of the foot is relevant in kinematic analyses of gait. Images captured through a lens can be subjected to various aberrations or distortions that affect the measurements. An in vitro study was performed with a rearfoot simulator to compare the apparent degrees (photographed) with the real ones (placed in the simulator) in the plane of the rearfoot's orientation, according to variations in the capture angle in other planes of space (the sagittal plane and transverse plane-the latter determined by the foot progression angle). The following regression formula was calculated to correct the distortion of the image: real frontal plane = 0.045 + (1.014 × apparent frontal plane) - (0.018 × sagittal plane × foot progression angle). Considering the results of this study, and already knowing its angle in the transverse and sagittal planes, it is possible to determine the angle of a simulated calcaneus with respect to the ground in the frontal plane, in spite of distortions caused by perspective and the lack of perpendicularity, by applying the above regression formula. The results show that the angular measurements of a body segment made on frames can produce erroneous data due to the variation in the perspective from which the image is taken. This distortion must be considered when determining the real values of the measurements.

Effectiveness of custom-made foot orthoses in patients with systemic lupus erythaematosus: protocol for a randomised controlled trial.

INTRODUCTION: Systemic lupus erythaematosus (SLE) is a chronic autoimmune disease of heterogeneous involvement. The disease may affect feet with a high prevalence of symptoms such as, for example, pain, forefoot and rearfoot deformities, and biomechanics dysfunctions. Custom-made foot orthoses (CMFO) have been previously reported to be effective in patients with other rheumatic diseases. However, as far as the authors know, there exist no studies about their effectiveness in SLE. This study aims at determining the effect of CMFO versus placebo flat cushioning insoles on pain, foot functionality, fatigue and quality of life in patients with SLE. METHODS AND ANALYSIS: A randomised controlled trial would compare the effects of (1) CMFO and group B, which received a placebo, flat cushioning insoles, for 3 months. The main outcome measures are foot pain, foot functionality and foot-related disability. The secondary outcome measures are fatigue and quality of life. ETHICS AND DISSEMINATION: The study has been approved by the Portal de Ética de la Investigación Biomédica de Andalucía ethical committee 1494-N-19. The results will be disseminated regardless of the magnitude or direction of effect. TRIAL REGISTARTION NUMBER: Clinicaltrials.gov identifier NCT04098055.

Polyethylene Nail Brace for Ingrown Toenails Treatment: A Randomized Clinical Trial.

Background: Onychocryptosis is one of the most prevailing onychopathies and one of the usual reasons for visiting podiatry clinics. In this research, we aim to evaluate the effectiveness of a procedure of nail reeducation technique via a strip of polyethylene in subjects with stage I or IIa onychocryptosis, in which pathological toenail curves are present. Methods: This research was a randomized clinical trial (ACTRN12615000834550). The sample was made up of 94 cases of stage I or IIa onychocryptosis, according to the Mozena classification. Briefly, 46 cases were treated with the combination of a spicule technique and nail brace with a polyethylene plastic strip, and 48 were only treated with the spicule technique. Results: The combination of the spicule technique and the nail brace technique with a strip of polyethylene had a significantly lower recurrence rate compared to that achieved with just the spicule technique, twelve months after the beginning of the study (N.S. = 0.000 for α = 0.05). The change in the nail width achieved with the nail brace technique, twelve months after the beginning of the study, was statistically significant (N.S. = 0.000 for α = 0.05). Conclusions: The recurrence rate of the spicule technique alone was significantly higher than the combined technique of spicule with nail brace. A nail brace with a strip of polyethylene reduces the recurrence rate of onychocryptosis.

Psychosocial Influence of Ehlers-Danlos Syndrome in Daily Life of Patients: A Qualitative Study.

(1) Background: Ehlers-Danlos syndrome is a heterogeneous group of connective tissue disorders causing pain, fatigue, and disabilities; it has several implications for patients who suffer from this disease. The major clinical manifestations of EDS include joint hypermobility, skin hyperextensibility, and generalized connective tissue fragility. This research aims to explore their perceptions and experiences about the phycological and social spheres. (2) Methods: Semistructured interviews were carried out. Participants were encouraged to talk about issues related to their disease by asking open-ended questions in one to one interview. The interview guide included questions to identify the syndrome's influence on the social and psychological life of patients All interviews were audio recorded, fully transcribed, and analyzed using the phenomenological theoretical framework. The method of analysis was the thematic interpreting of perspectives and approaches. (3) Results: 31 individuals were proposed to participate in this study. Five patients refused to participate, so a total of 26 interviews were performed. Six themes ((1) Pain and its consequences on a daily basis; (2) The need to name the problem: the diagnosis; (3) Restructuring leisure and social relationships; (4) Limitations due to economic conditions; (5) Psychological impact of the disease situation; (6) Professional limitations) and four subthemes ((1) The value of partner support; (2) The weather influence on social plans; (3) Physical exercise and illness; (4) Support groups) emerged from the data. (4) Conclusions: This study revealed the impact of the syndrome on the social and daily life of patients, and not only in a physical level, but also in a psychological and social approach. These findings allow healthcare providers to know more about this disease in order to support and give advice to patients about the changes they will have to make.

Methicillin-Resistant Staphylococcus aureus Diabetic Foot Crossed Infection: A Case Report.

This work presents a protocol to prevent the transmission of multidrug-resistant infections. We focus on the Diabetic Foot Unit Podiatry Clinic Area attached to the University of Seville in particular. The most common complication for patients with diabetes is leg ulcers. Together with neuropathy, vasculopathy, and immunological response disorder, these individuals have a high predisposition to developing infections. Staphylococcus aureus is a highly prevalent microorganism in humans which, at times, may act as a pathogen. Due mainly to indiscriminate abuse of antibiotics, the methicillin-resistant strain known by its initials as MRSA is the most extended nosocomial infection globally and is a severe community and hospital healthcare problem. This paper describes compliance with new general recommendations on cleaning, hygiene, and decontamination, in addition to implementation of this specific protocol, after detection of cross infection (healthcare-related infection) in the studied unit in two patients with MRSA-infected ulcers. After an in-depth bibliographical review, strict hand hygiene measures and use of non-sterile gloves were used when treating all patients with a diabetic foot. Finally, we reflect on the need to educate healthcare personnel to guarantee correct prescription of selected antibiotics. The role of the podiatrist in the multidisciplinary team is highlighted not only in terms of management and treatment of lesions in diabetic patients, but also as a healthcare agent for the detection and prevention of MRSA together with other multidrug-resistant infections.

Custom-Made Foot Orthoses Reduce Pain and Fatigue in Patients with Ehlers-Danlos Syndrome. A Pilot Study.

BACKGROUND: Pain and fatigue are major clinical manifestations in patients with Ehlers-Danlos Syndrome (EDS). The aim of this study is to measure change of the effects of custom-made foot orthotics on some manifestations related to EDS, such as foot pain, foot functionality, fatigue, and quality of life. METHODS: Thirty-six patients with EDS wore foot orthoses for three months. Foot pain, foot-related disability, foot functionality, fatigue, and quality of life were measured using the 11-point Numeric Rating Scale, the Manchester Foot Pain and Disability Index, the Foot Function Index, the Fatigue Severity Score, and the 12-Item Short Form Health Survey questionnaires, respectively, at the beginning and after 3 months. RESULTS: Participants demonstrated significantly improved foot pain (p = 0.002), disability related to foot pain (p < 0.001), foot functionality (p = 0.001), fatigue (p < 0.007), and mental health-related quality of life (p = 0.016). The physical health-related quality of life did not show significant changes. CONCLUSIONS: The use of custom-made foot orthoses help in the management of the symptoms by participants. This study could contribute to the foot specialists being considered as an additional member in multidisciplinary teams that are trying to develop an approach for patients with EDS.

Static Range of Motion of the First Metatarsal in the Sagittal and Frontal Planes.

The first metatarsal and medial cuneiform form an important functional unit in the foot, called "first ray". The first ray normal range of motion (ROM) is difficult to quantify due to the number of joints that are involved. Several methods have previously been proposed. Controversy exists related to normal movement of the first ray frontal plane accompanying that in the sagittal plane. The objective of this study was to investigate the ROM of the first ray in the sagittal and frontal planes in normal feet. Anterior-posterior radiographs were done of the feet of 40 healthy participants with the first ray in a neutral position, maximally dorsiflexed and maximally plantarflexed. They were digitalized and the distance between the tibial malleolus and the intersesamoid crest in the three positions mentioned was measured. The rotation of the first ray in these three positions was measured. A polynomic function that fits a curve describing the movement observed in the first ray was obtained using the least squares method. ROM of the first ray in the sagittal plane was 6.47 (SD 2.59) mm of dorsiflexion and 6.12 (SD 2.55) mm of plantarflexion. ROM in the frontal plane was 2.69 (SD 4.03) degrees of inversion during the dorsiflexion and 2.97 (SD 2.72) degrees during the plantarflexion. A second-degree equation was obtained, which represents the movement of the first ray. Passive dorsiflexion and plantarflexion of the first ray were accompanied by movements in the frontal plane: 0.45 degrees of movement were produced in the frontal plane for each millimeter of displacement in the sagittal plane. These findings might be useful for the future design of instruments for clinically quantifying first ray mobility.

Range of Ankle Dorsiflexion in a Group of Adults with Ligamentous Laxity.

BACKGROUND: Ligamentous or joint laxity is a clinical entity characterized by increased joint mobility beyond the range of motion regarded as normal, and joint mobility is an effective indicator of the degree of laxity. We examined the influence of ligamentous laxity on the range of ankle dorsiflexion with the knee flexed and extended, comparing lax adults with a control (nonlax) group. METHODS: The sample comprised 400 individuals: 200 in the control group (mean ± SD age, 32.49 ± 11.06 years) and 200 in the lax group (mean ± SD age, 29.82 ± 9.40 years). The Beighton criteria were applied to each participant to diagnose laxity or nonlaxity, and sex, age, and angle range of bilateral dorsiflexion with the knee extended and flexed were recorded. RESULTS: The mean ± SD dorsiflexion range with the knee straight was 16.14° ± 5.29° left ankle and 21.21° ± 4.93° right ankle in the lax group and 12.94° ± 4.17° left ankle and 17.08° ± 4.40° right ankle in the control group. The respective values with the knee flexed were 15.84° ± 5.31° and 21.21° ± 4.80° in the lax group and 12.95° ± 3.95 and 17.23° ± 4.25° in the control group. CONCLUSIONS: In this sample, ankle dorsiflexion range in the lax group was 4° bigger than that in the control group in both knee positions.

Evaluation of the Analgesic Effect of Combination Therapy on Chronic Plantar Pain Through the Myofascial Trigger Points Approach.

BACKGROUND: Closely related pathologic disorders sometimes manifest with the same symptoms, making for a complex differential diagnosis. This is the situation in plantar fasciitis (PF) and myofascial pain syndrome (MPS) with myofascial trigger points (MTPs) in the sole of the foot. This research assessed the analgesic effect on plantar pain of combination therapy with interferential current stimulation therapy (ICST), treating MTPs in the great toe adductor muscle and the short flexor muscles of the toes in patients whose diagnosis was compatible with PF or MPS. METHODS: This study included 22 feet of 17 patients with a diagnosis compatible with PF or MPS with MTP. Participants received combination therapy with ICST for 15 sessions, and the decrease in pain was measured with an algometer and the visual analog scale. Both measurements were taken before and after every fifth session. The pressure pain threshold (PPT) results obtained with the Student t test and the pain intensity perception (PIP) results obtained with the Wilcoxon signed rank test were analyzed by comparing the measurements taken before the treatment and after the fifth, tenth, and 15th sessions. RESULTS: The decrease in PIP was significant after the fifth, tenth, and 15th sessions ( P < .001). The increase in PPT was also significant after the fifth ( P = .010), tenth ( P = .023), and 15th ( P = .001) sessions ( P < .05). CONCLUSIONS: The suggested combination therapy of ultrasound with ICST is clinically significant for reducing plantar pain after 15 treatment sessions, with a 6.5-point reduction in mean PIP and a 4.6-point increase in PPT.
