Contortion

Contortion, also known as contortionism, is a performance art where artists, called contortionists, demonstrate extreme physical flexibility. These acts are commonly part of acrobatics, circus shows, street performances, and other live entertainment, always performed in front of an audience. A typical act features one or more performers executing a choreographed series of moves or poses, often set to music, that demand a level of flexibility far beyond what most people possess. The audience is drawn to the dramatic, seemingly impossible feats of bending.

A performer's flexibility is influenced by factors like age, genetics, body type, and strict physical training. Most contortionists are classified as either "frontbenders" or "backbenders," based on which direction their spine bends most easily, and very few are equally skilled in both. People with hypermobility, such as those with Ehlers-Danlos syndrome (EDS), may have a greater range of motion, but this can also cause joint instability and a higher injury risk. That is why extensive strength training and conditioning are crucial to stabilize joints and prevent overextension. Common skills include frontbending moves like folding forward at the waist with straight legs or placing one or both legs behind the neck or shoulders (a human knot). Backbending skills include touching the head to the feet or to the buttocks (a head-seat) while standing, lying down, or in a handstand. A Marinelli bend is a backbend supported only by gripping a short post held in the mouth. Splits and oversplits (beyond 180 degrees) can appear in either frontbending or backbending acts, sometimes with feet supported by chairs or assistants. Enterology, also called body packing, involves squeezing into a small, knee-high box that seems too small to hold the performer. Some acts feature dislocations of the shoulders or hips as a short novelty, such as lifting an arm sideways until it passes behind the head and rests across the shoulders, sometimes called bone breaking.

Contortionists with hypermobility face a higher risk of joint dislocations, subluxations, and soft tissue injuries due to their increased range of motion and reduced joint stability. However, the idea that contortionists always suffer long-term injuries is a myth. Many develop exceptionally strong core and stabilizing muscles, which are key for preventing injury. Few people can safely attempt extreme poses, so the required strength is often underestimated. Medical research on this is limited. A 2008 study by Peoples and colleagues used whole-spine dynamic MRI on five contortionists aged 20 to 49, finding limbus vertebrae, disc bulges, and disc degeneration in some, with three reporting back pain. Because the sample was very small, these findings are preliminary and cannot be applied to all contortionists. They suggest extreme spinal movements might contribute to certain changes, but more research with larger groups is needed. It is also worth noting that many contortionists retire in perfect health, showing that with proper conditioning, technique, and strength training, long-term musculoskeletal health is possible. Good conditioning, proprioceptive training, and injury prevention strategies are vital to reduce risks.

Contortion acts vary widely, often including humor, drama, shock, sensuality, or a mix of styles. Contortion can be part of other performances like dance and theater. An adagio act is an acrobatic dance where one partner lifts and carries the other while they perform splits and other flexible poses. In a rag doll or golliwogg act, assistants bend, shake, and carry the contortionist to create the illusion of a limp, life-sized doll, often ending by stuffing the performer into a small box. Poses can be done on a Spanish web, an aerial rope with a hand or foot loop spun by someone below. Contortionists may also manipulate props, such as spinning hula hoops, juggling rings, balancing towers of wine glasses, or playing an instrument—like Max Smith, known as "The Musical Contortionist," who played the banjo while contorted. A performer may work alone, with one or two assistants, or in a group of up to four. In the past, contortionists were mostly found at circuses and fairs, but now they also perform in nightclubs, amusement parks, magazine ads, trade shows, TV variety shows, music videos, and as warmup acts or background performers at concerts. The Ross Sisters were American contortionists famous for their musical number "Solid Potato Salad" in the 1944 film *Broadway Rhythm*. Today, contortion photos and digital clips are traded by fans online, and some websites offer original photos for a monthly fee or sell videotapes by mail. Some loose-jointed individuals can pop a joint out of its socket without pain, making it difficult to detect.
