Sensory function after traumatic upper extremity amputation in the human
Judith Patricia Hunter
Written in English
Awareness of a phantom limb (PLA) as an integral part of the body is experienced by almost every individual after amputation. This awareness can be accompanied by specific qualities of sensation (PLS) and/or pain (PLP) in the missing limb. The neural mechanisms underlying these phenomena are not known. Previous hypotheses focused on PLP and were primarily based on data obtained in subjects evaluated several years after their amputation. Furthermore, these studies were potentially confounded by age effects and/or coexisting injuries or disease. The present thesis tested the main hypothesis that phantom awareness is a distinct phantom phenomenon reflecting an altered interaction of multiple sensory inputs and does not reflect cutaneous sensory thresholds. Prospective evaluations (interviews, quantitative sensory testing) were conducted in an unselected cohort of otherwise healthy individuals early (<6 months) after unilateral traumatic upper limb amputation. A subset of subjects was followed longitudinally (∼two years). Prevalence and longitudinal data indicated that spontaneous PLA (mostly a stiff, flexed phantom hand) is the most common and stable phantom experience, suggesting that these perceptions reflect conscious body awareness. Spontaneous PLP, PLS, stump pain and evoked PLS/PLA were less prevalent and varied individually over the time period examined. Furthermore, despite a common injury, there was no consistent pattern of abnormalities in tactile or thermal sensory function in the stump. Sensory thresholds did not reflect the quality of the subjective phantom limb experience. These data indicate that (1) the relative contribution of specific mechanisms can vary between individuals and over time and, (2) PLS and PLA are not related in any simple way to cutaneous sensory function. Furthermore, a mirror box illusion was used to examine the interaction and effects of vision and sensorimotor inputs on perceived PLA. Real and illusory visual information about limb position that produced subtle changes in congruence of visual, tactile, and sensorimotor information enhanced spontaneous PLA and dampened evoked PLA. In conclusion, PLA reflect an altered interaction of sensory inputs that normally maintain body awareness and not a specific cutaneous sensory deficit. Spontaneous PLA could arise from a mismatch between expected and actual sensory signals concerning body location.

Feb 13, · Limb amputation is generally perceived as a failure of therapy, instead of an opportunity to provide functional restoration. The traditional approach to extremity amputation suffers from a lack of Author: Shriya S. Srinivasan, Maurizio Diaz, Matthew Carty, Hugh M. Herr. Traumatic upper extremity amputation is a life-altering incident, and salvage of function depends on accurate surgical management and postoperative rehabilitation. Several injuries necessitate amendment amputation and postoperative prosthesis fitting.

Oct 30, · For example, a T10 complete spinal cord injury patient with unilateral lower extremity amputation can achieve good ADL after rehabilitation due to the intact upper limb function. However, when an upper limb is amputated, ADL will be adversely dr-peshev.com by: 4. The effect of tactile and visual sensory inputs on phantom limb awareness within the 14 months after traumatic upper extremity amputation, (ii) evoked dual percepts are less common than.
Jul 30, · The classifications for levels of upper extremity amputation are described anatomically and are illustrated in Fig. The term disarticulation describes an amputation through the joint.
From proximal to distal, the term intrascapular thoracic describes an amputation of the entire upper extremity, scapula, and dr-peshev.comumeral describes an amputation through the humerus, also known as. Jun 23, · Pain after amputation involves nociceptive pain, due to bone and soft tissue injury, and neuropathic pain from direct neural trauma and central sensitization.
The incidence is unknown in medical amputees but has been found in up to 63% of patients after traumatic amputation. 4 This can be inferred clinically as patients with upper limb Cited by: 6.
