Active clinical trials for "Flatfoot"

People with anatomical leg length discrepancy (LLD) commonly presented excessive subtalar pronation of the long leg compared to their short leg in order to equalize leg length. Although such compensation may decrease the stress in the pelvis and/or low back region, the pronated foot may lead to excessive stress loading onto the ankle or foot, resulting in musculoskeletal injuries. Clinically, the pronated foot has been effectively controlled using functional orthoses with proper posting by adjusting the subtalar joint in the neutral position. But for people with compensatory pronated foot resulted from anatomical LLD, to control excessive pronation of the long leg would exaggerate their asymmetry in leg length. Instead, the pronated foot can be controlled simply by adjusting the length of the short leg. However, there is limited evidence of such intervention in previous literature. The purpose of this research project is going to determine the effect of leg length adjustment on pronation control in people with anatomical LLD. According to this purpose, 5 study objectives will be developed: 1) to examine the validity and reliability of LLD measurement using a hand-held laser distance meter, 2) to compare the foot types before and after leg length adjustment, 3) to compare the kinetic variables before and after leg length adjustment during quiet stance, 4) to compare the kinetic variables before and after leg length adjustment during level walking, and 5) to compare symptoms and functional levels related to low back pain (LBP) before and after leg length adjustment. The present research project will be designed as a convenience sampling, prospective, quasi-experimental, and pretest/posttest design. There will be 2 parts in this research: 1) validity and reliability test of laser measure for leg length and 2) foot morphology and kinetic analysis before and after leg length adjustment. For the first part of this research, 10 male adults and 20 adults will be recruited for the validity and reliability tests respectively. Anthropometric measurements, including body height, body weight, foot length, foot width, and heel-ball distance, will be measured after a consent form is signed. Participants of the validity test will receive standing pelvic radiography and laser measure to measure their leg length. Each participant of the reliability test will receive 2 sessions of laser measure using a hand-held laser-distance meter. For the first session, all laser measurements will be employed twice by 2 raters with a rest interval of more than 5 min. One week later, another session of laser measure will be given again by one of these 2 raters. Intraclass correlation coefficient (ICC) will be used to test the interrater reliability, intrarater reliability, and validity of the laser measure method. Standard error of measurement (SEM), and small real difference (SRD) will be calculated to represented intrarater reliability also. For the second part of the research, another thirty adults with compensatory pronated foot resulted from LLD will be included in the research project but the sample size will be adjusted to the appropriate number according to power analysis. Each participant will be asked to fill out the visual analog scale (VAS) and the Oswestry Disability Index (ODI) and receive tests containing foot type examination, quiet stance with eye opening, quiet stance with eye closed, and level walking. All tests will be performed before and after leg length adjustment. The experiment will be completed after collecting 3 successful trials for each test. All procedures will be done one month later. ANOVA with repeated measures will be calculated to compare the differences in these variables among before, immediately after, and 1 month following leg length adjustment when the data fit the assumptions of normal distribution. Discrete variables or variables with non-normal distribution were tested using the Friedman test. All statistical analyses will be calculated using SAS 9.1.3. The significant level was set at α = 0.05 while the power was at 0.8. Five possible results may be expected from conducting this research project: 1) there will be good validity and reliability of the laser distance meter to measure LLD, 2) there will be significant differences in measurements of foot type before and after leg length adjustment, 3) there will be significant differences in kinetic data during quiet stance before and after leg length adjustment, 4) there will be significant differences in kinetic data during level walking before and after leg length adjustment, and 5) symptom and functional level related to LBP will improve after leg length adjustment. Completion of this research project will be projected to provide solid and objective evidences for leg length adjustment through views of morphology and kinetics in people with pronated foot due to anatomical LLD.

Morphological weight bearing computed tomography parameters and gait analysis can implement the evaluation of the flat foot. Weight bearing CT is useful to verify the severity of the 3D deformities typical of flat foot, while kinematic and kinetic variables of gait is able to quantify the functional improvements of the foot after surgery.

Pes planus, sometimes known as flat feet, is one of these disorders and is characterized by a collapsed medial longitudinal arch, hindfoot eversion, and forefoot abduction. Pes planus is a musculoskeletal condition that causes hip, knee, and foot discomfort. According to a descriptive cross-sectional survey, 17% of school-aged children, 64% men and 34% females have flat foot deformity. Talonavicular joint is responsible for translating inversion and eversion movements of the foot. Mobilization of the Talonavicular joint helps in the improvement of joint dysfunction caused by inappropriate or bad posture via the proprioceptors. Rigid tape also known as low dye tape is defined as non-elastic zinc oxide tape used by physical therapists to stabilize a joint and limit movement. The conventional rigid tape is frequently used with non-contractile tissue, which then acts similarly to a ligament to limit joint mobility and prevent joints from moving into dangerous or end range positions.

The plantar fascia is a thick, multi-layered, non-elastic fibrous tissue band that extends along the plantar surface of the foot.The configuration of the plantar fascia is generally considered as a dense, longitudinally arranged fiber band divided into medial, central, and lateral components. The most significant functional role of the plantar fascia is to maintain the arch structure of the foot, providing a stable support base while standing and absorbing dynamic reaction forces during walking.Pes planus is a rather general term with many definitions. Staheli described pes planus as a "foot with a broad base of support," commonly known as flatfoot in layman's terms. In a study involving 80 female participants aged 65 and older, 90% of foot deformities observed while standing were identified as pes planus. Generally, pes planus is a condition characterized by excessive pronation of the rear part of the foot and a lowering of the medial longitudinal arch. During the push-off phase of walking, the pronation moment generated by the ground reaction force flattens the arch as the subtalar joint rotation combines. The shift in position in the talus bone causes the navicular bone to drop. The plantar calcaneonavicular ligament tightens, and the tibialis posterior muscle lengthens. Abnormalities in the bones of the foot, dysfunction of the tibialis posterior muscle, Achilles tendon shortening, or muscle weakness can contribute to pes planus. Individuals with pes planus may experience foot and leg pain with exercise, physical activity, and prolonged walking, which can limit their level of physical activity. Research has examined the relationship between pes planus and various physical parameters, and it has been found that one of these parameters, balance, is negatively affected by the presence of pes planus.

Thirty-six subjects randomly distributed between a dry needling intervention group and a control group whose intervention is a non-emission laser. All the subjects will be measured before and after the interventions of each group. The measurements will be made on a pressure platform to record the dynamic footprint variables.

The purpose of this study is to compare computer aided design/computer aided manufacturing (CAD/CAM) and semi-custom insole types on pain, quality of life and physical performance and also to decide whether they are necessary in treatment of painful flexible flatfoot.

The post-operative treatment of pediatric patients operated for the correction of flat foot, sees today the use of preformed leg-foot splint (Walker) as an alternative to the application of plaster casts. The change of the immobilization system has led to the appearance of problems of tolerability in particular in the skin. The problems persist also after placing a polyurethane foam dress at the heel in the immediate postoperative period. The aim of this study is to evaluate the effectiveness of a cotton sock applied inside the leg-foot splint in children operated vs the Elastic Compression Wraps in reducing the incidence of cutaneous lesions.
