Plantar pressures determinants in mild Hallux Valgus.
2010
While podobarometric techniques have been applied to the study of pressures in Hallux Valgus (HV), little is known about its clinical and radiological determinants. So, the aim of the present study was to determine the plantar pressure pattern in participants with mild HV, comparing to a control group, and their clinical and anthropometric determinants. Biofoot/IBV(®) in-shoe system was used to evaluate 79 participants with mild HV. Computerized measurements of the 1st intermetatarsal angle (IMA) and the hallux abductus angle (HAA) were made on antero-posterior radiographs. The clinical outcome was assessed using the AOFAS score. The dependent baropodometric variables and the independent cl…
Diabetic foot syndrome as a possible cardiovascular marker in diabetic patients
2015
Diabetic foot ulcerations have been extensively reported as vascular complications of diabetes mellitus associated with a high degree of morbidity and mortality; in fact, some authors showed a higher prevalence of major, previous and new-onset, cardiovascular, and cerebrovascular events in diabetic patients with foot ulcers than in those without these complications. This is consistent with the fact that in diabetes there is a complex interplay of several variables with inflammatory metabolic disorders and their effect on the cardiovascular system that could explain previous reports of high morbidity and mortality rates in diabetic patients with amputations. Involvement of inflammatory marke…
Effects of Strength Training on Neuromuscular Function and Disease Activity in Patients with Recent-onset Inflammatory Arthritis
1994
Thirty-nine consecutive patients with recent-onset rheumatoid or psoriatic arthritis were randomly allotted for six months period either to the experimental progressive dynamic strength training group (EG, 10 women and 11 men; 41 +/- 10 yrs), or to the control group (CG, 10 women and 8 men; 45 +/- 11 yrs) who just maintained their habitual physical activities. All patients received antirheumatic medication throughout the experimental period. During the study period significant improvements took place in the EG in maximal muscle strength of all examined muscle groups (31.5% for the knee extensors, p0.001; 14.8% and 10.7% for the trunk flexors and extensors, p0.01; 27.8% and 20.4% for grip st…
Interdisciplinary treatment of diabetic foot wounds in the elderly : Low risk of amputations and mortality and good chance of being mobile with good …
2016
Aims: A major proportion of patients with diabetic foot syndrome are older than 65 years. Little is known about outcomes of these elderly patients. Methods: We analysed 245 treatment cases in an observational single-centre study for comorbidities and outcomes over a 6-month period. Results: In all, 122 patients had peripheral arterial disease which was significantly increasing with age ( n = 245, df = 1, χ2 = 23.06, p ⩽ 0.0001). Increasing age correlated positively with decreasing rate of revascularisations ( n = 122, df = 1, χ2 = 4.23, p = 0.039). In total, 23 (9.3%) patients died in the observation period. In-hospital mortality was 2.8%, percentage of major amputations 2.8%. In the invasi…
Influence of somatosensory input on motor function in patients with chronic stroke.
2004
In healthy volunteers, reduction of somatosensory input from one hand leads to rapid performance improvements in the other hand. Thus, it is possible that reduction of somatosensory input from the healthy hand can influence motor function in the paretic hand of chronic stroke patients with unilateral hand weakness. To test this hypothesis, we had 13 chronic stroke patients perform motor tasks with the paretic hand and arm during cutaneous anesthesia of the healthy hand and healthy foot in separate sessions. Performance of a finger tapping task, but not a wrist flexion task, improved significantly with anesthesia of the hand, but not the foot. This effect progressed with the duration of anes…
Influence of foot orthosis customisation on perceived comfort during running
2014
Although running is associated with many health benefits, it also exposes the body to greater risk of injury. Foot orthoses are an effective strategy to prevent such injuries. Comfort is an essential element in orthosis design since any discomfort alters the runner's biomechanics, compromising performance and increasing the risk of injury. The present study analyses the perceived comfort of three types of orthoses: custom-made, prefabricated and original running shoe insoles. Nine comfort variables for each insole were assessed in a sample of 40 runners. Custom-made and prefabricated insoles were both perceived as significantly more comfortable than the original insoles. The differences wer…
Sprint mechanical properties in soccer players according to playing standard, position, age and sex.
2020
The purpose of this study was to quantify possible differences in sprint mechanical outputs in soccer according to soccer playing standard, position, age and sex. Sprint tests of 674 male and female players were analysed. Theoretical maximal velocity (v
The impact of Syme amputation in surgical treatment of patients with diabetic foot syndrome and Charcot-neuro-osteoarthropathy
2002
Charcot-neuro-osteoarthropathy with its severe destruction of bones remains a challenge for physicians and surgeons. The aim of the study was to characterise a patient population treated in a specialised foot care centre who underwent surgical treatment for their diabetic foot syndrome. Special attention was paid to patients who suffered from Charcot-neuro-osteoarthropathy and the impact of Syme amputation if amputation of the foot was inevitable. A total of 121 patients with diabetic foot syndrome and ulcerations underwent an interdisciplinary strategy for diagnostic and therapeutic procedures including MRI and surgical interventions. If peripheral arterial vessel disease was present, reva…
Force in the Achilles Tendon During Walking With Ankle Foot Orthosis
2009
Background Ankle foot orthoses are used for postoperative treatment of Achilles tendon ruptures and decrease calf muscle electromyography activity during walking. Hypothesis Achilles tendon load decreases with increased restriction of dorsiflexion and is associated with decreased triceps surae activity. Study Design Controlled laboratory study. Methods In 8 subjects, the maximum force and rate of force development in the Achilles tendon were measured with an optic fiber technique, and the activity of the gastrocnemius, soleus, and tibialis anterior muscles was recorded using electromyography. Trial conditions were walking barefoot and wearing an ankle-foot orthoses set in 3 different positi…
Kinematics reduction applied to the comparison of highly-pronated, normal and highly-supinated feet during walking
2019
Abstract Background Kinematic analysis could help to study how variations in the static foot posture affect lower limb biomechanical function. The analysis of foot kinematics is complex because it involves managing the time-dependent joint angles in different joints and in all three planes of motion. But it could be simplified if joint angles are coordinated. Methods The kinematics of the ankle, midtarsal and metatarsophalangeal joints were registered in 20 highly-pronated, 30 normal and 20 highly-supinated subjects (assessed by the Foot Posture Index – FPI) as they walked barefoot. Coordination for each sample was analysed through principal component analysis applied to the dorsiflexion, a…
