Bondage, in the BDSM subculture, is the practice of consensually tying, binding, or restraining a partner for erotic, aesthetic, or somatosensory stimulation. A partner may be physically restrained in a variety of ways, including the use of rope, cuffs, bondage tape, or self-adhering bandage.
Physical restraint refers to means of purposely limiting or obstructing the freedom of a person's bodily movement.
A straitjacket is a garment shaped like a jacket with long sleeves that surpass the tips of the wearer's fingers. Its most typical use is restraining people who may cause harm to themselves or others. Once the wearer slides their arms into the sleeves, the person restraining the wearer crosses the sleeves against the chest and ties the ends of the sleeves to the back of the jacket, ensuring the arms are close to the chest with as little movement as possible.
Handcuffs are restraint devices designed to secure an individual's wrists in proximity to each other. They comprise two parts, linked together by a chain, a hinge, or rigid bar. Each cuff has a rotating arm which engages with a ratchet that prevents it from being opened once closed around a person's wrist. Without the key, the handcuffs cannot be removed without specialist knowledge, and the handcuffed person cannot move their wrists more than a few centimetres or inches apart, making many tasks difficult or impossible.
The hogtie is a method of tying the limbs together, rendering the subject immobile and helpless. Originally, it was applied to pigs and other young four-legged animals.
Bondage in BDSM is the activity of tying or restraining people using equipment such as chains, cuffs, or collars for mutual erotic pleasure. According to the Kinsey Institute, 12% of females and 22% of males respond erotically to BDSM.
A splint is defined as "a rigid or flexible device that maintains in position a displaced or movable part; also used to keep in place and protect an injured part" or as "a rigid or flexible material used to protect, immobilize, or restrict motion in a part". Splints can be used for injuries that are not severe enough to immobilize the entire injured structure of the body. For instance, a splint can be used for certain fractures, soft tissue sprains, tendon injuries, or injuries awaiting orthopedic treatment. A splint may be static, not allowing motion, or dynamic, allowing controlled motion. Splints can also be used to relieve pain in damaged joints. Splints are quick and easy to apply and do not require a plastering technique. Splints are often made out of some kind of flexible material and a firm pole-like structure for stability. They often buckle or Velcro together.
Cock and ball torture (CBT) is a BDSM or sexual activity involving the application of pain or constriction to the penis or testicles. This may involve directly painful activities, such as genital piercing, wax play, genital spanking, squeezing, ball-busting, genital flogging, urethral play, tickle torture, erotic electrostimulation, kneeing or kicking. The recipient of such activities may receive direct physical pleasure via masochism, or emotional pleasure through erotic humiliation, or knowledge that the play is pleasing to a sadistic dominant. Many of these practices carry significant health risks.
Suspension bondage is a form of sexual bondage where a bound person is hung from one or more overhead suspension points. It carries a higher risk than other forms of sexual bondage.
An orthopedic cast, or simply cast, is a shell, frequently made from plaster or fiberglass, that encases a limb to stabilize and hold anatomical structures—most often a broken bone, in place until healing is confirmed. It is similar in function to a splint.
A body belt is any waist belt which has D-rings or other attachment points. The belts can be used as medical restraints in institutions for bed and wheelchair restraints, and for safety in activities such as abseiling or construction work. When they are used in sexual bondage plays they are commonly referred to as bondage belts, and also worn in fetish clothing. The belts are usually fastened with buckles and some by a locking mechanism, which enables quick release.
External fixation is a surgical treatment wherein Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing. As an alternative to internal fixation, wherein bone-stabilising mechanical components are surgically emplaced in the body of the patient, external fixation is used to stabilize bone tissues and soft tissues at a distance from the site of the injury.
Medical restraints are physical restraints used during certain medical procedures to restrain patients with (supposedly) the minimum of discomfort and pain and to prevent them from injuring themselves or others.
Weighted clothing are garments that have heavy materials incorporated into them, to add weight to various parts of the body, usually as part of resistance training. The effect is achieved through attaching weighted pieces to the body which leave the hands free to grasp objects. Unlike with held weights or machines, weighted clothing can leave users more able to do a variety of movements and manual labour. In some cases certain weighted clothing can be worn under normal clothing, to disguise its use to allow exercise in casual environments.
A tuilik is an Inuit watertight jacket, used when paddling a kayak. It is sealed at the face, at the wrists and around the cockpit coaming. In this way the paddler can capsize and come back upright without getting wet, and without getting any water into the kayak.
Locking clothing are garments which prevent the person wearing the clothing from removing the clothing. One example would be clothing designed to prevent a person with dementia from inappropriate undressing. Sometimes locking clothes are used for sexual purposes, such as in feminization.
A mobility aid is a device designed to assist walking or otherwise improve the mobility of people with a mobility impairment.
A belly chain is a physical restraint worn by prisoners, consisting of a chain around the waist, to which the prisoner's hands may be chained or cuffed. Sometimes the ankles are also connected by means of longer chains.
An armbinder or monoglove is a type of restraint device primarily used in bondage play, designed to bind the arms and/or hands to each other or to the body, usually behind the back, and employing a range of bondage equipment including cuffs, rods, straps, and gloves.
Surgical positioning is the practice of placing a patient in a particular physical position during surgery. The goal in selecting and adjusting a particular surgical position is to maintain the patient's safety while allowing access to the surgical site. Often a patient must be placed in an unnatural position to gain access to the surgical site.
