Locomotor Effects Of Shoes
Locomotor effects of shoes are the way in which the physical characteristics or components of shoes influence the locomotion neuromechanics of a person. Depending on the characteristics of the shoes, the effects are various, ranging from alteration in balance and posture, muscle activity of different muscles as measured by electromyography ( EMG), and the impact force. There are many different types of shoes that exist, such as running, walking, loafers, high heels, sandals, slippers, work boots, dress shoes, and many more. However, a typical shoe will be composed of an insole, midsole, outsole, and heels, if any. In an unshod condition, where one is without any shoes, the locomotor effects are primarily observed in the heel strike patterns and resulting impact forces generated on the ground. Insoles and inserts The foot provides the sensory information to the central nervous system through cutaneous afferent feedback, which originates from the special mechanoreceptors withi ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) is a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane term does not refer to the single type of polymer but a group of polymers. Unlike polyethylene and polystyrene, polyurethanes can be produced from a wide range of starting materials resulting in various polymers within the same group. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and polyurethane laminate (PUL). Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting a polymeric isocyanate with a polyol. Since a ...

High-heeled Footwear
High-heeled shoes, also known as high heels (colloquially shortened to heels), are a type of shoe with an upward-angled sole. The heel in such shoes is raised above the ball of the foot. High heels cause the legs to appear longer, make the wearer appear taller, and accentuate the calf muscle. There are many types of high heels in varying styles, heights, and materials. High heels have been used in various ways to convey nationality, professional affiliation, gender, and social status. High heels have been an important statement piece of fashion for centuries in the West. High heels spread from equestrian origins with the 10th century Persian galesh to wider fashion use. In early 17th-century Europe, high heels were a sign of masculinity and high social status. Towards the end of the century, the trend began to spread to women's fashion. By the 18th century, high-heeled shoes had split along gender lines. By this time, heels for men were chunky squares attached to riding boot ...

Eversion (kinesiology)
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomica ...

Valgus Deformity
A valgus deformity is a condition in which the bone segment distal to a joint is angled outward, that is, angled laterally, away from the body's midline. The opposite deformation, where the twist or angulation is directed medially, toward the center of the body, is called varus. Knee arthritis with valgus knee Rheumatoid knee commonly presents as valgus knee. Osteoarthritis knee may also sometimes present with valgus deformity though varus deformity is common. Total knee arthroplasty (TKA) to correct valgus deformity is surgically difficult and requires specialized implants called constrained condylar knees. Examples * Ankle: ''talipes valgus'' (from Latin ''talus'' = ankle and ''pes'' = foot) – outward turning of the heel, resulting in a 'flat foot' presentation. * Elbows: '' cubitus valgus'' (from Latin ''cubitus'' = elbow) – forearm is angled away from the body. * Foot: ''pes valgus'' (from Latin ''pes'' = foot) – a medial deviation of the foot at subtalar join ...

Tibialis Posterior
The tibialis posterior muscle is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg. It is the key stabilizing muscle of the lower leg. Posterior tibial tendonitis Posterior tibial tendonitis is a condition that predominantly affects runners and active individuals. It involves inflammation or tearing of the posterior tibial tendon, which connects the calf muscle to the bones on the inside of the foot. It plays a vital role in supporting the arch and assisting in foot movement. This condition can cause pain, swelling, and potentially lead to flatfoot if left untreated. Structure The tibialis posterior muscle originates on the inner posterior border of the fibula laterally. It is also attached to the interosseous membrane medially, which attaches to the tibia and fibula. The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus. It terminates by dividin ...

Varus Deformity
A varus deformity is an excessive inward angulation ( medial angulation, that is, towards the body's midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. The terms varus and valgus always refer to the direction that the distal segment of the joint points. For example, in a valgus deformity of the knee, the distal part of the leg below the knee is deviated ''outward, in relation to the femur,'' resulting in a '' knock-kneed'' appearance. Conversely, a ''varus'' deformity at the knee results in a '' bowlegged'' with the distal part of the leg deviated ''inward, in relation to the femur''. However, in relation to the mid-line of the body, the knee joint is deviated towards the mid-line. Terminology The terminology is made confusing by the etymology of these words. * The terms ''varus'' and ''valgus'' are both Latin, but confusingly, their Latin meanings conflict with their current usage. In current usage, as noted above, a varus deformity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pronation Of The Foot
Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three Anatomical plane, cardinal plane components: Subtalar joint, subtalar Anatomical terms of motion#Inversion and eversion, eversion, ankle Anatomical terms of motion#Flexion and extension of the toes sole foot, dorsiflexion, and forefoot Anatomical terms of motion#Abduction and adduction, abduction, these three distinct motions of the foot occur simultaneously during the pronation phase. Pronation is a normal, desirable, and necessary component of the Bipedal gait cycle, gait cycle. Pronation is the first half of the Bipedal gait cycle#Phases, stance phase, whereas supination starts the propulsive phase as the heel begins to lift off the ground. Types The normal biomechanics of the foot absorb and direct the occurring throughout the gait whereas the foot is flexible (pronation) and rigid (supination) during different phases of the gait cycle. As the foot is loade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running Economy
Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. Oxygen consumption (VO2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism. Those who are able to consume less oxygen while running at a given velocity are said to have a better running economy. However, straightforward oxygen usage does not account for whether the body is metabolising lipids or carbohydrates, which produce different amounts of energy per unit of oxygen; as such, accurate measurements of running economy must use and data to estimate the calorific content of the substrate that the oxygen is being used to respire. In distance running, an athlete may attempt to improve performance through training designed to improve running economy. Running economy has been found to be a ...

Metatarsophalangeal
The metatarsophalangeal joints (MTP joints) are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes. They are analogous to the knuckles of the hand, and are consequently known as toe knuckles in common speech. They are condyloid joints, meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges). The region of skin directly below the joints forms the ball of the foot. The ligaments are the plantar and two collateral. Movements The movements permitted in the metatarsophalangeal joints are flexion, extension, abduction, adduction and circumduction. File:The feet of C. H. Unthan, the armless fiddler Wellcome L0034227.jpg, Left: toes adducted (pulled towards the center) and spread (abducted); right, both feet clenched (plantar flexed) File:Footgym rings1.jpg, The upper foot is clenching (plantarflexing) at the MTP joints and at the joints of the to ...

Gastrocnemius
The gastrocnemius muscle (plural ''gastrocnemii'') is a superficial two-headed muscle that is in the back part of the lower leg of humans. It is located superficial to the soleus in the posterior (back) compartment of the leg. It runs from its two heads just above the knee to the heel, extending across a total of three joints (knee, ankle and subtalar joints). The muscle is named via Latin, from Greek γαστήρ (''gaster'') 'belly' or 'stomach' and κνήμη (''knḗmē'') 'leg', meaning 'stomach of the leg' (referring to the bulging shape of the calf). Structure Origin/proximal attachment The lateral head originates from the lateral condyle of the femur, while the medial head originates from the medial condyle of the femur. Insertion/distal attachment Its other end forms a common tendon with the soleus muscle; this tendon is known as the calcaneal tendon or Achilles tendon and inserts onto the posterior surface of the calcaneus, or heel bone.
