In shibari, the term refers to an extreme and dangerous posture often seen in porn films, applied to actresses in scenes that usually involve some kind of enema. This is because the posture itself makes it easy to show that procedure on camera: the body is folded and compacted, with the legs raised, the arms placed “in front” of them and the pelvic area fully exposed. It is a technique frequently used in both Osada Ryu and Yagami Ryu. According to Yagami Ren, for a tie to count as *daruma shibari* it must meet certain conditions, as with *teppo shibari*: seen from the front, it must have a round shape like the *daruma* figure, all four limbs must be immobilized and the knees must be at shoulder height or above. He describes it as a visceral compression tie, in principle for flexible people, which compresses the diaphragm and lungs like the *ebi zeme*, so breathing becomes shallow and it cannot be held for long. In its full version, the arms are taken behind the back in a position close to the *gote*. Yagami Ren claims to have developed a safer variant, the *daruma shibari* of his style (鵺神式達磨縛り). The *daruma* position subjects the body to a combination of global trunk flexion, sustained flexion of the spine and forced tilting of the pelvis, producing significant compression of the abdominal cavity. From a biomechanical point of view, this configuration increases the compressive and shear loads on the lumbar spine, the sacroiliac joints and the hips, while changing the distribution of tension in the muscles and fascial tissues. One of the most relevant effects of this position is the loss of **alignment of the breathing cylinder**. In our methodology, the breathing cylinder is understood as the functional unit formed by the glottis, the diaphragm, the abdominal wall and the pelvic floor. Under optimal conditions, these elements stay aligned and coordinated, allowing efficient breathing, proper regulation of intra-abdominal pressure and effective stabilization of the trunk. The extreme flexion typical of the *daruma* position breaks this alignment, limits diaphragmatic excursion and disrupts the coordination between its components, reducing both ventilatory efficiency and the system's ability to stabilize the body's axis. This disruption also affects the *core*. Although the stabilizing muscles remain active, their ability to generate intra-abdominal pressure and effectively stabilize the spine decreases because of the body's extreme position. In a suspension, where the ropes partly replace the usual supports, this loss of stabilizing efficiency increases reliance on passive structures —ligaments, intervertebral discs and joint capsules— to bear the loads, raising the mechanical stress on the spine. Sustained compression of the abdomen increases pressure on the abdominal organs and can hinder venous and lymphatic return from the pelvis and lower limbs, especially when the position is held for long periods or combined with suspension. Although these changes are usually minor in healthy people, they are an added risk factor for paresthesia, postural intolerance or localized circulatory compromise. Regardless of how it is usually portrayed in adult films, the marked trunk flexion and forced orientation of the pelvis produce a sustained lengthening of the muscles and connective tissue of the pelvic region, altering their length-tension relationship and temporarily reducing their ability to contract efficiently and take part in lumbopelvic stabilization. Therefore, this position does not produce significant indirect stimulation in people with internal genitals, since it adopts a configuration consistent with an expulsive pattern, in which the orientation of the pelvis, the reduced contractile capacity of the pelvic floor and the limited active movement do not favor the physiological mechanisms usually associated with the sexual response. Arousal and pleasure depend on the interaction of complex neurological, vascular, muscular and psychological factors, and there is no evidence that this body configuration increases stimulation on its own. The position does, however, change the spatial orientation of the pelvis and restrict the voluntary movement of the person in it, circumstances that can facilitate certain forced penetrative practices, since their ability to readjust their body is limited. This effect is purely mechanical and should not be read as an increase in arousal or pleasure. Visually, the *daruma* position may recall *Tittibhasana* (*Firefly Pose*) in yoga. However, the resemblance is purely aesthetic. *Tittibhasana* is an active, stable, self-supported posture, held through the coordinated activation of the *core*, the shoulder girdle and the deep pelvic muscles. In the *daruma* position, by contrast, the body depends on the support of the ropes and is subjected to a completely different load pattern, both in magnitude and in direction. Overall, *daruma* has an unfavorable risk-benefit balance. The increased loads on the spine and pelvis, the loss of alignment of the breathing cylinder, the reduced stabilizing efficiency of the lumbopelvic complex and the absence of clearly identifiable functional or physiological benefits mean its use cannot be considered an efficient technique. Consequently, at Shibari Dojo Online we advise against practicing it. If, having read all of the above, you decide to do it anyway, its use should be limited to exceptionally controlled contexts, for short periods and only with precise knowledge of the risks involved and the measures needed to mitigate them. ## Custom Fields **Content Type — The formal and communicative nature of a piece of content, based on its documentary function.:** Glossary **Knowledge Type — The nature of knowledge according to its role within practice.:** Technique **Field of Study — The specific area of practice that the content focuses on.:** Body **Corpus — A structured body of reference knowledge that underpins the content.:** Anatomy **Criteria — A cross-cutting perspective that defines the emphasis or intent from which the content is approached.:** Safety **Summary — A brief synthesis of the content that presents its main topics, purpose, or most relevant aspects.:** Biomechanical analysis of an extreme posture: risks, effects and why we advise against it.
