Efeito agudo da terapia manual na mobilidade articular tíbio-társica de indivíduos diabéticos / Acute effect of manual therapy on ankle joint mobility in diabetic patients

Mendonça Junior, Emilson Sodré 13 November 2018 (has links)
O Diabetes Mellitus (DM) é uma doença de grande prevalência, e um dos principais problemas de saúde pública em todo o mundo, tendo como complicações o déficit no desempenho funcional dos membros inferiores, que podem interferir na manutenção do equilíbrio, além de ser um forte preditor de limitações funcionais. Os indivíduos acometidos pelo diabetes apresentam predisposição à redução da mobilidade da articulação tíbio-társica. A terapia manual é frequentemente utilizada com a finalidade de melhorar a amplitude de movimento. O objetivo do estudo foi avaliar o efeito agudo da terapia manual na mobilidade articular do tornozelo de pacientes diabéticos. Foram avaliados 40 voluntários, de ambos os sexos com média de idade de 59,35±7,85 anos, portadores de DM tipo 2 com limitação da amplitude da articulação tíbio-társica, divididos em dois grupos: grupo Sham (GS), submetido a tratamento simulado e follow up de sete dias, e grupo intervenção (GI), submetido a intervenção manual manipulativa e follow up de sete dias. A análise da amplitude de movimento articular foi efetuada por meio de goniometria digital, e a descarga estática de peso avaliada por baropodometria computadorizada com olhos abertos e fechados. A distribuição dos dados foi avaliada pelo teste de normalidade de Shapiro-Wilk. Diante de uma distribuição normal e relacionada, foram utilizados os testes ANOVA seguido de pós-hoc de TuKey. Para as variáveis que apresentaram distribuição não normal, foi utilizado o teste Kruskal-Wallis, seguido do pós-hoc de Dunn. Foi utilizado software estatístico SAS e considerado nível de significância de 5%. Os resultados demonstraram aumento da amplitude de movimento articular, nas flexões plantares e dorsiflexões, direita e esquerda, do GI entre o momento inicial e os momentos pós-manipulação, bem como após sete dias da intervenção terapêutica (follow-up). Também houve diferença significativa entre o GI quando comparado ao GS nos momentos pós e follow-up. Com relação ao efeito clínico da intervenção ao longo do tempo, a análise intragrupo mostrou que no GS não ocorreu diferença entre os registros de amplitude de movimento comparando-se o momento pré-intervenção com os registros subsequentes (pós e follow-up), tanto para os movimentos de flexão plantar como de dorsiflexão, em ambos os lados. Em relação a descarga de peso plantar estática verificou-se alteração de valores registrados para o pico de pressão total no pé, dos lados direito e esquerdo no GI, entre os momentos pós-intervenção imediata e na aferição 7 dias após a intervenção manipulativa (follow-up), para registro com olhos abertos. Com relação às comparações intragrupos ao longo do tempo (pré, pós-intervenção e follow-up), foi observada diferença significativa para a condição amplitude de deslocamento anteroposterior (DAP) com olhos abertos do GI, observando-se incremento após a intervenção e redução no followup. Diante dos resultados obtidos, pode-se inferir que a intervenção aguda com terapia manual produz incremento da amplitude articular do tornozelo de indivíduos diabéticos. / Diabetes Melittus (DM) is a disease of great incidence, and one of the main public health problems worldwide, having as complications the deficit in the functional performance of the lower limbs, which can interfere in the maintenance of the balance, besides being a Strong predictor of functional limitations. Individuals affected by diabetes are predisposed to reduce the mobility of the tibial-tarsal joint. Manual therapy is often used for the purpose of improving range of motion. The objective of this study is to evaluate the acute effect of manual therapy on ankle joint mobility in diabetic patients. 40 volunteers, aged 59,35±7,85 years, DM type 2 and tibial-tarsal joint amplitude limitation, of both genders were recruited, divided into two groups: group 1 (Sham: submitted to evaluations and follow up of seven days), and group 2 (intervention: submitted to the evaluations, manipulative manual intervention, with follow up of seven days). The analysis of joint range of motion was acessed by digital goniometry and the static discharge of weight was evaluated by baropodometry computed with open and closed eyes. After tabulation of variables, the Shapiro-Wilk normality test was applied to analyze the distribution. Before a normal and related distribution, ANOVA followed by Tukey post-hoc tests were used. For the variables that presented a non-normal distribution, the Kruskal-Wallis test was used, followed by the Dunn post-hoc test. For the variables that presented a non-normal distribution, the Kruskal-Wallis test was used, followed by the Dunn post-hoc test. The SAS software was used and a significance level of 5% was considered. The results showed an increase in joint range of motion, in the right and left dorsiflexions of the GI between the initial moment and the postmanipulation moments, as well as after seven days of the follow-up. There was also a significant difference between GI when compared to GS in the post and follow-up moments. Regarding the clinical effect of the intervention over time, the intragroup analysis showed that in GS there was no difference between the amplitude of movement registers comparing the pre-intervention moment with the subsequent records (post and follow-up), even for plantar and dorsiflexion flexion movements on both sides. In relation to static plantar weight discharge, there was a change in recorded values for the peak of total foot pressure, on the right and left sides of the GI, between the moments after the immediate intervention and in the measurement 7 days after the manipulative intervention (follow -up), for registration with open eyes. Regarding intra-group comparisons over time (pre, post-intervention and followup), a significant difference was observed for the condition amplitude of anteroposterior displacement (DAP) with open eyes of the GI, observing an increase after intervention and reduction in the follow-up. In view of the obtained results, it can be inferred that the acute intervention with manual therapy produces an increase in the joint amplitude of the ankle of diabetic individuals

First metatarsophalangeal joint range of motion : influence of ankle joint position and gastrocsoleus muscle stretching

North, Ian Graham January 2008 (has links)
[Truncated abstract] First metatarsophalangeal joint (MTPJ1) motion is an important factor in normal weight transference during walking. Disruptions to normal range can influence joints both proximal and distal to the MTPJ1, potentially leading to pain and dysfunction. Whilst the MTPJ1 has been investigated significantly, the numerous methodologies described to quantify range of motion can be questioned and makes comparisons difficult. Range of MTPJ1 motion is commonly assessed in a clinical setting to determine pathology as well as to make decisions on appropriate intervention. The anatomical and biomechanical influence of tendo Achilles load and MTPJ1 motion has been well described; however few studies measuring MTPJ1 range control for Achilles load or describe ankle joint positioning. Further to this the effects of reducing tendo Achilles stiffness on MTPJ1 extensions has yet to be investigated. The purpose of this study was to describe a technique to quantify passive MTPJ1 extension and to determine the influence of ankle joint position on joint range. Secondly the effect of calf muscle stretching on MTPJ1 range was also investigated. The information gathered will assist both research and clinical protocols for quantifying MTPJ1 range, and provide a greater understanding of the anatomic and biomechanical relationship between tendo Achilles load and MTPJ1 extension. In order to fulfil the purposes of the study it was necessary to establish a reliable methodology to quantify non weight bearing MTPJ1 extension. Reliability testing was undertaken in three parts. '...' The results demonstrated a statistically significant increase in joint range immediately following a one minute stretch for variables ankle joint range of motion as well as MTPJ1 extension for ankle joint plantar flexed at 10 Newton's and ankle joint neutral and plantar flexed at 30 Newtons. No significant differences were noted in ankle or MTPJ1 range of motion in either the control group on immediate re-testing, or in both groups after a one week stretch program. The findings of this study support those documented in the literature pertaining to the ankle joint position, tendo Achilles load and plantar fascial stiffness to MTPJ1 range of motion. Increased stiffness at the MTPJ1 was noted dependant on ankle joint position from ankle joint plantar flexion through to ankle joint dorsiflexion. This appears most likely due to increases in tendo Achilles load and subsequent forces transmitted to the plantar aponeurosis. The present study also demonstrated a trend towards increased joint extensibility and limb dominance. The study also supports previous literature into gender differences and joint extensibility, with a positive trend towards increased MTPJ1 range evident in the female subjects tested. The study also demonstrated the immediate effect of calf muscle stretching on ankle and MTPJ1 range of motion. It remains however unclear as to the exact mechanisms involved in producing increased joint range be it reflex inhibition or actual changes to the viscoelastic properties of the soft tissues. Despite this, no changes were evident following a one week stretching program, which supports previous literature describing a short lag time before soft tissues revert to baseline length properties following a single stretch session.

An investigation into the effect of stretching frequency on range of motion at the ankle joint

Trent, Vanessa Unknown Date (has links)
Stretching is a widely prescribed technique that has been demonstrated to increase range of motion. Consequently it may enhance performance and aid in the prevention and treatment of injury. Few studies have investigated the frequency of stretching on a daily basis. The purpose of this study was to investigate the effect of stretching frequency on range of motion at the ankle joint. The detraining effect was also investigated after a period without stretching. Thirty-one female subjects participated in this study. They were randomly assigned to a control group who did not stretch a group who stretched two times per week (Stretch-2) or a group who stretched four times per week (Stretch-4). The stretching intervention was undertaken over four weeks and targeted the gastrocnemius and soleus muscles. Each stretch was held for duration of 30 seconds and repeated five times. Prior to the intervention (PRE), dorsiflexion was measured using a weights and pulley system that passively moved the ankle joint from a neutral position into dorsiflexion. After the four week stretching period (POST), dorsiflexion was measured once again to determine the change following the stretching programme. Following a further four week period where no stretching took place (FINAL), dorsiflexion was measured to determine the detraining effect. Electromyography was used to monitor the activity of the plantarflexors and dorsiflexors during the measuring procedure. The results of the study showed a significant increase in ankle joint range of motion for the Stretch-4 group (p<0.05) when comparing PRE and POST measurements. The Stretch-2 and control groups did not show significant differences (p>0.05) between PRE and POST measurements. When comparing the PRE and FINAL measurements of the Stretch-4 group, no significant differences were recorded (p>0.05). The POST and FINAL measurements were significantly different (p<0.05). After the detraining period the Stretch-4 group lost 99.8% of their range of motion gains. The present data provide some evidence that the viscoelastic properties of the muscle stretched were unchanged by the four week static stretching programme. The mechanism involved in the observed increase in range of motion for the Stretch-4 group is possibly that of enhanced stretch tolerance of the subject. Further research is required to support this conjecture.

Closed Loop Control of the Ankle Joint Using Functional Electrical Stimulation

Tan, John Frederick 14 July 2009 (has links)
The restoration of arm-free standing in paraplegic individuals can be accomplished with the help of functional electrical stimulation (FES). The key component of such a system is a controller that can modulate FES induced muscle contractions in real-time, such that artificially produced forces in the legs and abdominal muscles are able to generate stable standing posture. A 57 year-old individual with chronic ASIA-A (American Spinal Injury Association), T3/4 level spinal cord injury (SCI) participated in this study. The objective was to determine if a proportional-derivative (PD) or proportional-integral-derivative (PID) controller could be used to regulate FES induced muscle contractions in the ankle joint to allow it to maintain balance of the entire body during quiet standing, while exhibiting physiological dynamics seen in able-bodied individuals while doing so.

Chronic lateral instability of the ankle joint : natural course, pathophysiology and steroradiographic evaluation of conservative and surgical treatment

Löfvenberg, Richard January 1994 (has links)
Chronic lateral instability of the ankle (CLI), defined as frequent sprains and recurrent giving way, difficulty in walking and running on uneven surface, is often connected with pain and swollen ankles. It occurs in 10 to 20 percent after acute ankle injuries. Mechanical instability of the talocrural and subtalar joint, peroneal weakness and impaired proprioception has been suggested as etiological factors. Aim. To investigate the natural course in conservatively treated patients with CLI. To assess the mechanical stability in patients with CLI by measuring the three dimensional motions in the talus, the fibula and the calcaneus in relation to the tibia during different testing procedures pre- and postoperatively. To determine if CLI is associated with proprioceptive deficiency. Patients and Methods. This Thesis includes 127 ankles in 78 patients (30 women, 48 men) with CLI. Thirty-seven patients were followed up 20 years after their first contact with the orthopaedic department because of CLI. Forty-six ankles were evaluated radiographically and the result was compared with a gender- and age - matched control-material. The neuromuscular response to a sudden angular displacement of the ankles was studied in 15 ankles in 13 patients using EMG. Thirty-six patients entered a prospective study using roentgen stereophotogrammetric analysis (RSA) in which the ankles were tested at manual adduction, adduction with predetermined torque, with and without external support and at drawer tests (40 N and 160N). Twenty-seven patients were followed five years postoperatively. Result. After 20 years 22 patients, conservatively treated still suffered from instability of the ankle and ten had recurrent giving way symptoms even on plane surface. Six ankles in the patient group and four in the control group displayed osteoarthritic changes Prolonged ipsilateral reaction time (m. per. long, and m. tib. ant.) was found in patients with CLI indicating proprioceptive insufficiency. Increased talar adduction and a tendency toward increased total translation of the talar center was found in ankles with CLI. Concomitant fibular rotations and translations were found but with no conclusive deviation in the ankles with symptoms. The talo-calcaneal adduction reached the same level in the patient and control groups regardless of symptoms. External support (ankle brace) increased the talar stability. The use of predetermined torque and constrained testing procedure did not add information compared with the manual test Twenty-five patients graded the result as excellent or good five years after lateral ligament reconstruction. Talar stability (decreased adduction and translation) was increased two years postoperatively and was improved or remained the same at five years without comprising the range of motion. Conclusion. In more than half the cases symptoms of CLI did not resolve spontaneously. Minor degenerative changes was found after twenty years, but not to a greater extent than in a control group. CLI was associated with proprioceptive insufficiency and talocrural but not subtalar instability. Increased ankle stability can be obtained by the use of an ankle brace and by an anatomical ligament reconstruction. / <p>Diss. (sammanfattning) Umeå : Umeå universitet, 1994</p> / digitalisering@umu
