Body integrity identity disorder (BIID) is a rare condition defined by a persistent desire to amputate or paralyze a healthy limb (usually one or both of the legs). This desire arises from experiencing a mismatch between the internal body model and the actual physical/functional boundaries of the body. People with BIID show an abnormal physiological response to stimuli approaching the affected (unwanted) but not the unaffected leg, which might suggest a retracted peripersonal space (
a multisensory integration zone near the body) around the unwanted limb. Thus, using a visuo-tactile interaction task, we examined leg PPS in a group of healthy men and three men with BIID who desired unilateral leg amputation. PPS size (~ 70 cm) around the unwanted BIID legs did not differ from that of healthy controls. Although the leg feels foreign in BIID, it still seems to maintain a PPS, presumably to protect it and facilitate interactions within the surrounding environment.

Distorted representations of the body and peripersonal space are common in Complex Regional Pain Syndrome (CRPS), and might modulate its symptoms (e.g. asymmetric limb temperature). In pain-free peopl...
Humans perceive near space and far space differently. Peripersonal space (PPS), i.e. the space directly surrounding the body, is often studied using paradigms based on auditory-tactile integration. In...
Converging evidence suggests that peripersonal space has dynamic properties, which can be influenced by motor and cognitive factors. Here, we investigated whether changes in self-perception may impact...
Peripersonal space (PPS) representation is modulated by information coming from the body. In paraplegic individuals, whose lower limb sensory-motor functions are impaired or completely lost, the repre...
In migraine, there is an altered behavior of patients during the attack and an altered connectivity in the cortical structures modulating and encoding the sensation and pain. Thus, we hypothesized tha...
In this study, we wish to find behavioral evidence for the question whether an amputation of the arm can lead to changes in visual perception or motor responses to objects in peripersonal ...
A tourniquet is used to stop abundant bleeding when simple compression is not effective. The investigators will study the vascular suffering of the tourniquets according to their location ...
The goal of this study is the evaluation of lower limb function and the quaility of life of the patients after femur fracture operation treatment. LLTQ (Lower-Limb Tasks Questionnaire), LE...
Patients with limb amputations experience the sensation of the missing extremity, which is sometimes coupled with a persistent and debilitating pain in the missing limb, a condition known ...
This study aims to: 1. validate the Finnish version of the Musculoskeletal Tumor Society scale and the Toronto Extremity Salvage Score lower extremity sections and to 2. a...
The region of the lower limb in animals, extending from the gluteal region to the FOOT, and including the BUTTOCKS; HIP; and LEG.
Full gratification of a need or desire followed by a state of relative insensitivity to that particular need or desire.
Distinct regions of mesenchymal outgrowth at both flanks of an embryo during the SOMITE period. Limb buds, covered by ECTODERM, give rise to forelimb, hindlimb, and eventual functional limb structures. Limb bud cultures are used to study CELL DIFFERENTIATION; ORGANOGENESIS; and MORPHOGENESIS.
Severe cellulitis of the submaxillary space with secondary involvement of the sublingual and submental space. It usually results from infection in the lower molar area or from a penetrating injury to the mouth floor. (From Dorland, 27th ed)
The region of the lower limb between the FOOT and the LEG.
