“…The benefit of a possible double incorporation is perhaps most obvious in the case of mechanical prostheses, where an amputee's attitude toward his or her prosthetic limb depends on both the functionality of the prosthesis (i.e., how well it can be operated), and the extent to which the prosthesis is experienced as a part of the self (Desmond and MacLachlan, 2002). Although both types of incorporations are expected to depend highly on sensorimotor integration, the exact underlying mechanisms may be different.…”

a b s t r a c tWhat explains the experience of ''being there'' in a simulated or mediated environment? In recent years, research has pointed to various technological and psychological factors deemed important in eliciting this so-called experience of telepresence, including interactivity, sensory-motor integration, media transparency, and distal attribution. However, few theories exist that can combine these findings in a coherent framework. In the present paper, we formulate such a theoretical framework. We will argue that the experience of telepresence is a consequence of the way in which we are embodied, and that it extends naturally from the same ability that allows us to adjust to a slippery surface, or to the weight of a hammer. The importance of embodiment in the understanding of telepresence has been stated before, but these works have not yet fully addressed what it means to be embodied. We argue that ''having a human body'' means having a specific morphology, a body schema, and a body image. Subsequently we describe how tools and technological artifacts may be incorporated at each of these levels of embodiment, and the implications thereof for the experience of telepresence.

“…Furthermore, they involve other problems such as abnormal behaviors (addiction to drugs or alcohol) and poor social performance. [812] The economic, social, personal, familial, and environmental problems are other problems faced by the people with amputations, making their life more difficult. [1013] Therefore, patients should employ strategies to manage their disease.…”

Introduction:The effect of amputation on an individual's psychological condition as well as family and social relationships is undeniable because physical disability not just affects the psycho-social adjustment, but also the mental health. When compared to normal people, such people are mostly experiencing social isolation. On the other hand, social support is known as the most powerful force to cope with stressful situations and it allows patients to withstand problems. The present study aims to explain understanding the trauma of patients and the experience of support sources during the process of adaptation to a lower limb amputation.Materials and Methods:The present study was conducted using qualitative content analysis. Participants included 20 patients with lower limb amputation due to trauma. Sampling was purposive initially and continued until data saturation. Unstructured interviews were used as the main method of data collection. Collected data were analyzed using qualitative content analysis and constant comparison methods.Results:The main theme extracted from the data was support sources. The classes include “supportive family”, “gaining friends’ support”, “gaining morale from peers”, and “assurance and satisfaction with the workplace.”Conclusion:Given the high number of physical, mental and social problems in trauma patients, identifying and strengthening support sources can be effective in their adaptation with the disease and improvement of the quality of their life.

“…From Table 1, N Gear = 340:36 and T motor = 6 mN m, approximately half of the motor stall torque from the datasheet. If a 10% efficiency loss is assumed for each stage (which is consistent with our experience for a good planetary gear set), the overall efficiency of the six-stage gearbox is then h Gear = 0:9 6 . Using these values in equation 3give a projected torque applied at the DIP of 1085.3 mN m.…”

“…5 Amputation can cause physical, psychosocial, and economic damage to an individual and can lead to depression, anxiety, loss of self-esteem, and social isolation. 6,7 Over half of individuals with partial hand loss are unable to return to their prior occupations 8 and experience greater rates of post-traumatic stress and an increased negative perception of body image. 9 While the number of individuals with partial hand amputation is 10 times greater than that of all other categories of upper limb amputation combined, the prosthetic options for this patient population are relatively poor.…”

Partial hand loss accounts for the overwhelming majority of upper limb deficiencies. Despite this, individuals with partial hand loss have a limited number of prosthetic options at their disposal. Existing externally powered devices typically house both motor and gear transmission in the proximal phalanx, which provides function at the expense of anthropomorphism. We present a novel design for an externally powered finger prosthesis with a custom gear transmission that is capable of higher intermittent torques compared to commercial gearheads of equivalent volume. We manufacture a fully functional transmission using a high-strength maraging steel alloy and direct laser metal sintering. The transmission consists of multiple planetary and spur gear stages arranged in a stackable (or laminar) configuration and accommodates joint movement at the proximal interphalangeal joint. The powered finger is equivalent in size to a 50th percentile female index finger and is capable of generating pinch forces comparable to those of commercial powered fingers at flexion speeds that exceed those of existing devices. While there are several practical and functional improvements for future iterations, our design represents a viable option for a powered finger capable of accommodating a wide range of individuals with partial hand loss.
