These include the WRIST JOINT; CARPAL JOINTS; METACARPOPHALANGEAL JOINT; and FINGER JOINT.Flame Retardants: Materials applied to fabrics, bedding, furniture, plastics, etc. to retard their burning; many may leach out and cause allergies or other harm.AstrologyFoam Cells: Lipid-laden macrophages originating from monocytes or from smooth muscle cells.Quackery: The fraudulent misrepresentation of the diagnosis and treatment of disease.Theology: The study of religion and religious belief, or a particular system or school of religious beliefs and teachings (from online Cambridge Dictionary of American English, 2000 and WordNet: An Electronic Lexical Database, 1997)Monimiaceae: A plant family of the order Laurales, subclass Magnoliidae, class Magnoliopsida.Halogenated Diphenyl Ethers: Compounds that contain two halogenated benzene rings linked via an OXYGEN atom. Many polybrominated diphenyl ethers are used as FLAME RETARDANTS.Artificial Limbs: Prosthetic replacements for arms, legs, and parts thereof.AmputeesFeedback, Sensory: A mechanism of communicating one's own sensory system information about a task, movement or skill.Vibration: A continuing periodic change in displacement with respect to a fixed reference. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Prosthesis Design: The plan and delineation of prostheses in general or a specific prosthesis.Compulsive Behavior: The behavior of performing an act persistently and repetitively without it leading to reward or pleasure. The act is usually a small, circumscribed behavior, almost ritualistic, yet not pathologically disturbing. Examples of compulsive behavior include twirling of hair, checking something constantly, not wanting pennies in change, straightening tilted pictures, etc.Weight Lifting: A sport in which weights are lifted competitively or as an exercise.Bass: Common name for FISHES belonging to the order Perciformes and occurring in three different families.Forearm Injuries: Injuries to the part of the upper limb of the body between the wrist and elbow.Wrist: The region of the upper limb between the metacarpus and the FOREARM.Osteoarthritis: A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.Osteoarthritis, Knee: Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)Knee Joint: A synovial hinge connection formed between the bones of the FEMUR; TIBIA; and PATELLA.Superstitions: A belief or practice which lacks adequate basis for proof; an embodiment of fear of the unknown, magic, and ignorance.Nobel PrizeChronology as Topic: The temporal sequence of events that have occurred.Awards and PrizesVehicle Emissions: Gases, fumes, vapors, and odors escaping from the cylinders of a gasoline or diesel internal-combustion engine. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed & Random House Unabridged Dictionary, 2d ed)Social Media: Platforms that provide the ability and tools to create and publish information accessed via the INTERNET. Generally these platforms have three characteristics with content user generated, high degree of interaction between creator and viewer, and easily integrated with other sites.Wrestling: A sport consisting of hand-to-hand combat between two unarmed contestants seeking to pin or press each other's shoulders to the ground.Blogging: Using an INTERNET based personal journal which may consist of reflections, comments, and often hyperlinks.Resistance Training: A type of strength-building exercise program that requires the body muscle to exert a force against some form of resistance, such as weight, stretch bands, water, or immovable objects. Resistance exercise is a combination of static and dynamic contractions involving shortening and lengthening of skeletal muscles.Sports Equipment: Equipment required for engaging in a sport (such as balls, bats, rackets, skis, skates, ropes, weights) and devices for the protection of athletes during their performance (such as masks, gloves, mouth pieces).Agonistic Behavior: Any behavior associated with conflict between two individuals.Postural Balance: A POSTURE in which an ideal body mass distribution is achieved. Postural balance provides the body carriage stability and conditions for normal functions in stationary position or in movement, such as sitting, standing, or walking.Sensation Disorders: Disorders of the special senses (i.e., VISION; HEARING; TASTE; and SMELL) or somatosensory system (i.e., afferent components of the PERIPHERAL NERVOUS SYSTEM).Animal Identification Systems: Procedures for recognizing individual animals and certain identifiable characteristics pertaining to them; includes computerized methods, ear tags, etc.Tremor: Cyclical movement of a body part that can represent either a physiologic process or a manifestation of disease. Intention or action tremor, a common manifestation of CEREBELLAR DISEASES, is aggravated by movement. In contrast, resting tremor is maximal when there is no attempt at voluntary movement, and occurs as a relatively frequent manifestation of PARKINSON DISEASE.Mycolic AcidsNeck Pain: Discomfort or more intense forms of pain that are localized to the cervical region. This term generally refers to pain in the posterior or lateral regions of the neck.Essential Tremor: A relatively common disorder characterized by a fairly specific pattern of tremors which are most prominent in the upper extremities and neck, inducing titubations of the head. The tremor is usually mild, but when severe may be disabling. An autosomal dominant pattern of inheritance may occur in some families (i.e., familial tremor). (Mov Disord 1988;13(1):5-10)
