    Capturing the Perceived Phantom Limb through Virtual Reality
    (Office of the Vice Chancellor for Research, 2015-04-17) Lau, Jonathan; Huynh, Denver; Albertson, Steven; Beem, James; Qian, Enlin
    Phantom limb is the sensation amputees may feel where the missing limb (occasionally an organ) is still attached to the body and is still moving as it would if it were there. Between 50-80% amputees report neuropathic pain, also known as phantom limb pain (PLP). Recent studies suggest that providing sensory input to the stump or amputation area may modulate how PLP can be related to neuroplastic changes in the cortex. However, there is still little understanding of why PLP occurs and there are no fully effective, long-term treatments available. Part of the problem is the difficulty for amputees to describe the sensations of their phantom limbs due to the lack of a physical limb as well as phantom limbs that are in positions that are impossible to attain. This project aims to develop an effective 3D tool with the Maya 3D animation software and the Unity game engine. The tool will then be used for those with phantom limb syndrome to communicate the sensations accurately and easily through various hand positions using a model arm with a user friendly interface. The 3D model arm will be able to mimic the phantom sensation, being able to go beyond normal joint extensions of a regular arm. This way we can have a true 3D visual of how the amputee with phantom limb feels if it is abnormal. Testing the effectiveness of the tool will involve a pilot study with able-bodied volunteers. The non-dominant limb of the volunteers will be hidden behind a blind. After putting their limb in a random position, they will attempt to capture the limb on the 3D model. The actual position and captured position will be compared to determine the reproducibility and accuracy of the virtual limb. By taking advantage of computer graphics, virtual reality and computerized image capture technologies we are hoping to achieve a far less challenging way to quickly and accurately capture the position and striking feelings of the phantom limb sensation.

    Exploring How Expressive Art Interventions Impact Adults with Amputations
    (2022) Murphy, Baley; Misluk, Eileen; Alpers, Joan
    This study aims to understand how expressive art therapy interventions can impact adults with amputations. The 44 resources implemented in this thesis helped build a literary foundation and formulated themes seen within the literature. These themes included distorted self-image, feelings of loss and grief, complications with adjustment in daily life and with a prosthesis, phantom limb pain, changes to independent living and autonomy, and inadequate education pre- and-post-amputation. Four groups were proposed to inform, provide insight, and address the psychophysiological needs of individuals with amputations. Art therapy was utilized in all four groups. Three of the four groups integrated guided imagery, yoga, and boxing to enhance the therapeutic experience and achieve goals. Various needs of individuals with amputations were identified through an integrative narrative review research study. A literature matrix was used for data organization, and for data categorization, a thematic analysis was used (Betts & Deaver, 2019). These proposed groups can be used to track progress within the rehabilitation setting. These groups can increase a sense of safety, feelings of control and coherent communication, emotion regulation, strength through yoga and boxing exercises, acceptance of new body/ limitations, autonomy, mastery, strength, and confidence, foster a sense of community, and allow participants to self-reflect on their amputation journey. Expressive art therapies are beneficial for individuals with limb loss and should be implemented in rehabilitation to provide a transitional object that can help ease the transition from hospital to home.
