Study design: Controlled clinical test. Objectives: The purpose of this study was to assess the effects of quadriceps and anterior tibial muscles electrical stimulation on the feet and ankles of patients with spinal cord injuries and to compare them with able-bodied individuals and a group of patients who did not undergo neuromuscular electrical stimulation (NMES). Setting: This study was conducted at the Hospital das Clinicas of Unicamp, Campinas, Sao Paulo, Brazil. Methods: Between January and April 2008, 30 patients at the spinal cord injury ambulatory clinic who underwent NMES (group A) were submitted to a clinical and radiographic assessment of their feet and ankles and compared with a spinal cord injury group (group B) who did not undergo NMES and a group of able-bodied individuals (group C). The Kruskal-Wallis test was used to compare all the three groups, and between-group differences (P < 0.05) were investigated with the Mann-Whitney test. Results: The mean mobility of the midfoot and ankle subtalar joint was significantly higher in group C than in groups A and B. Differences in the mean measurements of the profiles of the talocalcaneal and the talus-first metatarsal angles were statistically significant for group A vs the other groups (P = 0.0020...

To evaluate the remodeling of collagen fibers in the articular cartilage of rat ankles, with and without immobilization, after application of muscle stretching protocol. Twenty three Wistar rats were divided into four groups: immobilized (I), n = 6; immobilized and stretched (IS), n = 6; stretched (S), n = 6 and control (C), n = 5. The animals in groups I and IS were submitted to immobilization. After the period of immobilization, the animals in groups IS and S were submitted to a muscle stretching protocol. At the end of the experiment, the animals were euthanized and the joints removed, processed and stained with Picrosirius red. The analysis was carried out using a polarized light microscope. The density of collagen fibers were quantified according to the intensity of birefringence displayed. By way of statistical analyses, the right and left hind limbs of the different groups were compared based on the total density of collagen fibers, the density of thick collagen fibers and the density of thin collagen fibers. Immobilization promoted a reduction in density of the thin fibers and of total collagen. The muscle stretching protocol after immobilization promoted a reduction in density of the total collagen and of the thick fibers...

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Medicina, 2007.; Objetivos: Avaliar a eficácia do tratamento com samário-153 hidroxiapatita (153Sm-HA) na artropatia hemofílica. Métodos: foram estudados 31 pacientes, 30 do sexo masculino, com idades entre 8 e 34 anos (média = 20,6 anos), com injeção intraarticular fixa de 185 MBq (5 mCi) de 153Sm-HA e divididos em dois grupos: 1- infanto-juvenil: 13 pacientes com até 18 anos, idade média de 12,7 anos e evolução da artropatia de 7,8 anos; 2- adulto: 18 pacientes com mais de 18 anos, idade média de 24 anos e evolução da artropatia de 18,7 anos. A avaliação clínica, antes e após um ano da sinovectomia, utilizou critérios subjetivos (dor por escala visual, inspeção da articulação) e objetivos (movimento articular pelo grau de flexão, sensibilidade à palpação e derrame pela sua circunferência), além da redução no uso do fator de coagulação, no número de hemartroses e a ocorrência de efeitos colaterais. Os resultados foram classificados em: 1- bom (remissão de 70% a 100% das manifestações); 2-moderado (remissão de 40% a 69%); 3- ruim (remissão de 0% a 39%). Foram tratadas 78 juntas: 15 joelhos; 36 cotovelos; 24 tornozelos; 1 ombro e 2 quadris. Foi realizado estudo cintilográfico precoce (1 a 2 h ) e tardio (24 a 72 h) após a sinoviortese. Foi também estimado o custo do procedimento por articulação. Resultados: não houve diferença significativa no resultado da sinovectomia entre os grupos infanto-juvenil e adulto. O resultado foi bom em 75% para cotovelos...

A patient with systemic lupus erythematosus (lupus) is described, in whom stress fractures of both legs developed, accompanied by swelling of both ankles. The swelling of the right ankle associated with fracture mimicked lupus synovitis, but resolved with healing of the fracture. On the left side the swelling represented true lupus synovitis coexistent with the tibial stress fracture. This presentation posed a diagnostic dilemma. It is necessary to maintain vigilance in the diagnosis of these fractures in lupus.

112 actively parachuting sport (free fall) parachutists with more than 200 descents each and 109 veteran military parachutists no longer active returned a postal questionnaire about their parachuting activities, injuries, and current and past musculoskeletal symptoms. A high frequency of fractures and injuries was reported by each group, both in relation to parachuting and to other activities. 58 sport parachutists aged 23 to 57 years (mean 33 - 3 years) had weight-bearing anteroposterior and lateral radiographs taken of each knee. These showed a prevalence of radiological osteoarthrosis of 10 - 4% which was mild in degree in all but one knee in one subject. 46 ex-military parachutists aged 50 to 70 years (mean 55 - 2 years) had weight-bearing anteroposterior radiographs taken of both knees and showed a prevalence of radiological osteroarthrosis of 41 - 3%. Moderate and severe changes were found in 10 - 9%. In both groups of parachutists six of the eight knee joints showing either moderate or severe radiological osteroarthrosis had been subjected to a previous meniscectomy. Forty ex-military parachutists had anteroposterior radiographs of the ankles (talotibial articulation) and showed a prevalence of osteoarthrosis of 17 - 5%, with the majority showing mild changes. There was a poor correlation between radiological osteoarthrosis...

Fifty-three physiotherapists working at professional soccer clubs responded to a postal questionnaire on the treatment of sprained ankles. Elevation, the application of ice and compression bandaging were commonly recommended for the first 24-48 hours followed by early mobilisation. A variety of other physiotherapy techniques were used and non steroidal anti-inflammatory drugs commonly dispensed. The application of these techniques to routine casualty practice is considered.

Radiological examination of the ankles of spina bifida children with flail lower limbs and valgus flat foot deformity has revealed a high incidence of abnormal valgus tilt of the ankle-joint. A study of ankle X-rays of spina bifida children before and after extra-articular subtalar fusion in which the bone graft is removed from the ipsilateral tibia has shown that the valgus tilt of the mortice may increase after this procedure.

A 27-year-old male started to have his ankles swollen during his military service. He was examined at a military hospital where electromyoneurography showed the signs of distal sensory-motor polyneuropathy with axon demyelinization and weak myopathic changes, whereas histopathological examination of gastrocnemius muscle biopsy revealed some mild and nonspecific myopathy. Besides, he was found to have subcutaneous ankle tissue edemas and hypertransaminasemia. Due to these reasons, he was dismissed from the military service and examined at another hospital where bone osteodensitometry revealed low bone mineral density of the spine. However, his medical problems were not resolved and after the second discharge from hospital he was desperately seeing doctors from time to time. Finally, at our institution he was shown to have celiac disease (CD) by positive serology (antitissue transglutaminase and antiendomysial antibodies) and small bowel mucosal histopathological examination, which showed total small bowel villous atrophy. Three months after the initiation of gluten-free diet, his ankle edema disappeared, electromyoneurographic signs of polyneuropathy improved and liver aminotransferases normalized. Good knowledge of CD extraintestinal signs and serologic screening are essential for early CD recognition and therapy.

This study aimed to define accelerations measured at the waist and lower extremities over a range of gait velocities to provide reference data for choosing the appropriate accelerometer for field-based human activity monitoring studies. Accelerations were measured with a custom activity monitor (±16g) at the waist, thighs, and ankles in 11 participants over a range of gait velocities from slow walking to running speeds. The cumulative frequencies and peak accelerations were determined. Cumulative acceleration amplitudes for the waist, thighs, and ankles during gait velocities up to 4.8 m/s were within the standard commercial g-range (±6g) in 99.8%, 99.0%, and 96.5% of the data, respectively. Conversely, peak acceleration amplitudes exceeding the limits of many commercially available activity monitors were observed at the waist, thighs, and ankles, with the highest peaks at the ankles as expected. At the thighs, and more so at the ankles, nearly 50% of the peak accelerations would not be detected when the gait velocity exceeds a walking velocity. Activity monitor choice is application specific, and investigators should be aware that when measuring high intensity gait velocity activities with commercial units that impose a ceiling at ±6g...

Many people living in developing countries still prefer to sit on the carpet or uncarpeted floor, and many times they sit in a cross legged position. Continuous rubbing and friction of the ankles over the carpet or the plain hard surface may cause callosity of the ankles. This can cause a cosmetic problem. We describe a case series of ankle hyperkeratosis referred to our outpatient clinic in Ahwaz in the south west of Iran from 2005–2010. These patients had localized hyperkeratosis on two ankles or the front of ankles. This article aims to help the clinician become more familiar with the morphological characteristic of this problem which may occur in people of Eastern origin.

Experimental data show that ankle torque is the most important actuator in normal human locomotion. I investigate the dynamics of simple models actuated by ankles alone. To assess the contribution of ankle actuation to locomotion, I first analyze the dynamics of some passive walkers without any joint torque. These passive walkers include a rimless wheel model and springy-legged models with and without a double stance phase. I analyze the stability of the period-one gait of each passive walker to compare it with the stability of the period-one gait of an ankle actuated model. Subsequently, I investigate whether balancing of a double inverted pendulum model whose shape and mass distribution are similar to a human can be achieved by control of ankle torque in a frontal plane. I study the dynamics of the model and design a controller that makes the model balance with biologically realistic ankle torque and a reasonable foot-floor friction coefficient. I conclude that an ankle-actuated model can make a stable period-one gait in a sagittal plane. Also, I deduce that the ankle torque control in a frontal plane can stabilize a double inverted pendulum model whose shape and mechanical properties are similar to those of humans.; by Jooeun Ahn.; Thesis (S.M.)--Massachusetts Institute of Technology...

Of 111 primary ankle ligament arthroplasties (modified Evans procedure) performed between 1983 and 1994, we were able to identify 89 patients (94 ankles) for follow-up. All were under 50 years of age. Two had died and one refused to co-operate; 86 patients (91 ankles) were therefore reviewed, 25 by telephone and the remainder by clinical examination with all but three also undergoing radiological review. Of the 91 ankles, 70 had no or very mild pain and 72 had no or rare episodes of instability and when considered together only 59 (65%) had no or mild pain and minimal instability. The results were supported by the Karlsson grading system. Clinical examination showed that 17 of the 66 ankles examined had increased inversion, while 21 had some limitation of inversion. Early degenerative changes were seen in 11 ankles, although only four had subtalar changes. These results show that this procedure does not give universally good clinical results. Patient satisfaction, however, was high with 97.7% being willing to undergo the same procedure if their other ankle became similarly affected.

A lesão medular causa prejuízos nos aspectos físico, psicológico e social da pessoa. Há predomínio de indivíduos do sexo masculino, jovens e o principal motivo são os acidentes automobilísticos. A lesão neurológica e o desuso dos membros acometidos produzem espasticidades, contraturas, osteoporose e deformidades, principalmente nos pés. Uma estratégia para diminuir estas complicações nos lesados medulares é a estimulação elétrica neuromuscular (EENM). Há poucos estudos na literatura descrevendo o comportamento de pés e tornozelos de lesados medulares submetidos à EENM, bem como sobre avaliação da osteoporose nestes indivíduos utilizando UQC (ultrassonografia quantitativa de calcâneo). Portanto, o objetivo principal deste estudo foi analisar os efeitos da EENM nos pés e tornozelos de lesados medulares e compará-los a grupo de lesados que não realizam EENM e a grupo de indivíduos normais. O objetivo secundário é avaliar a utilidade da ultrassonografia quantitativa de calcâneo no diagnóstico de osteoporose em lesados medulares. No período de janeiro a outubro de 2009, trinta pacientes do ambulatório de lesados medulares no Hospital das Clínicas da Unicamp que realizam EENM (Grupo A) tiveram seus pés e tornozelos submetidos à avaliação clínica e radiográfica e foram comparados a grupo de lesados que não realizam EENM (Grupo B) e a grupo de indivíduos normais (Grupo C). Foi também avaliada a densidade óssea utilizando UQC e densitometria óssea (DEXA) de 15 pacientes que iniciariam EENM no ambulatório de lesados medulares no Hospital das Clínicas da Unicamp (Grupo D)...

Current treatment strategies aim to achieve clinical remission in order to prevent the long-term consequences of rheumatoid arthritis (RA). Several composite indices are available to assess remission. All of them include joint counts as the assessment of the major 'organ' involved in RA, but some employ reduced joint counts, such as the 28-joint count, which excludes ankles and feet.

Kaminski, Thomas W.; BACKGROUND: Ankle sprains are the most common injuries among physically active people, with 40-70% developing functional ankle instability (FAI), characterized by frequent episodes of ???giving way??? and sensations of joint instability. Kinesio Taping,?? an intervention that has recently gained popularity may help decrease postural control deficits related to FAI. This study examined the immediate and prolonged effects of Kinesio Taping?? on postural control in subjects with FAI and investigated differences between healthy, coper, and unstable ankles as measured through single-limb balance on a forceplate. METHODS: Sixty physically active, college-aged participants (height: 172.5 ?? 9.7 cm, mass: 74.2 ?? 16.2 kg, age: 21.5 ?? 2.6 years) were sorted into three separate groups: healthy control, copers, and FAI. Subjects were stratified using the Cumberland Ankle Instability Tool (CAIT) combined with their history of ankle injury. Dependent variables were time to boundary (TTB) measures and traditional center of pressure (COP) measures in both the mediolateral (frontal) and anteroposterior (sagittal) planes. Testing was performed at baseline, immediately after application of the tape, 24 hours post-tape application...
