Helmet Therapy Vs. Conservative Therapy For The Treatment Of Positional Skull Deformations, Whitney Thompson

Physician Assistant Scholarly Project Posters

• Plagiocephaly and brachycephaly are skull deformations that occur in nearly half of all infants. These deformities are present at birth or can develop shortly after birth due to head positioning while lying supine. Depending on the severity of the deformity, infants may develop negative long-term developmental outcomes. There are generally two ways to treat such patients; repositioning or with use of orthotics (helmet therapy).

• A study of systematic reviews and cohort studies was completed to determine if orthotics (helmet) therapy is significantly more effective than repositioning therapy.

• The study indicated that infants diagnosed with moderate to severe …

3d Organ Printing, Chana Sirota

The Science Journal of the Lander College of Arts and Sciences

The global shortage of donor organs is a cause for countless fatalities across the world. Although, diseases can be treated through organ transplantation it can come along with many complications. Not only is there a high demand for donor organs, there is also the risk of the body’s rejection of the newly implanted organ. Through the method of 3D printing organs, many lives could be saved as well as reducing the need for donor organs. Finding materials to create a suitable scaffold is the focus of many experiments. Materials that are used in organ printing are made from soft materials, …

A New Technique To Improve The Operation Of Prosthetic Limbs During Muscle Fatigue, H. Albunashee, G. Rasool, K. Iqbal, G. White

Journal of the Arkansas Academy of Science

Prosthetic limbs hold a promise to renew the quality of life for the amputee. Neural commands are decoded via a classifier to generate control signals for the prosthetic devices. In the literature, many challenges and limitations have been identified that affect the prosthesis operation. One such drawback is muscle fatigue which degrades the surface electromyogram (sEMG) signals, and consequently, the performance of the deployed classification algorithm declines from 90% to 50% of average accuracy. We used a new technique using the Linear Discrimination Analysis (LDA) algorithm and the muscle synergy-based task discrimination (MSD) algorithm to improve the classification accuracy. In …

The Advances In Prosthetics, Jose Garcia

Symposium Of University Research and Creative Expression (SOURCE)

Throughout time, many people have been able to build, create, and do amazing things with their arms and legs. However, those who have lost limbs at birth or through an event in their life sometimes have a harder time being as accomplished as others. While some people without limbs have had a harder life, some have been able to accomplish what others with a normal physiology can by the use of prosthetics. This presentation will focus on the advances of prosthetics, the benefits for the user, and their future development. The main focus will be on prosthetic arms and their …

Postcolonial Disability In Mohesen Makhmalbaf’S Kandahar, Sukshma Vedere

Ray Browne Conference on Cultural and Critical Studies (2015-2021)

Kandahar (2001), an Iranian film directed by Mohsen Makhmalbaf, details the journey of the protagonist, Nafas, to Kandahar to save her sister from committing suicide on the day of the solar eclipse. The film has gained recent attention by disability studies scholars for the representation of disability in Afghanistan; scholars have discussed the significance of prosthetics and international aid for the disabled in post-war zones of the Third World, but little has been said about disability as a postcolonial embodiment. I argue that Kandahar represents the postcolonial state as a disabled space both literally and metaphorically. It projects the veil …

Designing Electronics For An Artificial Leg, Taylor Barto

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

A regenerative prosthesis is modeled and simulated. The simulation is optimized with the biogeography-based optimization algorithm to obtain desired knee angle tracking with a reference knee trajectory and to regenerate energy. The prosthesis is able to track a reference knee angle with a 5.1 degree error averaged over an entire stride and regenerate some energy throughout the stride.

Low-Cost Strider For Guatemala, Nicole Catherine Cooper, Gonzalo Hernandez, Jared W. Tower

Mechanical Engineering

The purpose of this project was to create a strider, a type of standing rehabilitation device, for children in developing countries who have trouble walking and supporting their full body weight. The project was initially brought to us by Cal Poly professor Brian Self, who had visited a clinic in San Marcos and determined that there were children there who had difficulties with walking and were a need for a rehabilitation device. The team discussed the problem with Dr. Self, Matt Robinson (a local San Luis Obispo prosthetist), and Cal Poly physics professor Pete Schwartz, all of whom had visited …

Biomechanical Analysis Of Gait Kinetics Resulting From Use Of A Vacuum Socket On A Transtibial Prosthesis, Maria De Lourdes Ramos Gonzalez

Honors College Theses

The technology and design of lower limb prosthetics have evolved greatly since their introduction. The current study proposed to compare the effects of a conventional pin socket attachment and a vacuum socket attachment for a transtibial amputee. Whereas traditional measurements of gait utilize force plates and camera systems, this study made use of a small tri-axial load cell located at the base of the socket to measure the forces and moments exerted during a regular gait cycle. The hypothesis tested stated that a vacuum pump socket attachment, when compared to a non-vacuum (pin) socket, will have a significant effect on …

Efficacy Of A Carbon Fiber Orthotic Toe-Off Brace In Adults With Cerebral Palsy, June Kume, John R. Magel, Erin Dicandia, Justine Hoffman, Robert Issing, Joshua Little, Tyler Roden

The School of Health Sciences Publications and Research

Purpose/Hypothesis : This pilot study evaluated the effects of a unique carbon fiber ankle/foot orthosis for individuals diagnosed with foot drop (“Toe-Off” design, Allard USA, Inc). We hypothesized that use of this brace would be useful for adults with cerebral palsy (CP) as evidenced by improved gait characteristics including gait endurance and balance.

Number of Subjects : A convenience sample of 4 patients, between the ages of 29 and 55, with diagnoses of cerebral palsy, was successfully recruited from United Cerebral Palsy (UCP) of Suffolk (Central Islip, NY). All individuals received regular physical therapy at UCP prior to and throughout …

Its All In The Mind: Mind Controlled Prosthetics, Tziril Joselit

The Science Journal of the Lander College of Arts and Sciences

The problem with prosthetics is a longstanding problem that researchers have been working on for many years. They are attempting to create a prosthetic that acts as if it is the original limb or body part. In recent years they have discovered a technology that has assisted many of those who are greatly in need of a prosthetic, such as an amputee or someone who is “locked in”. “Locked in” refers to a person who is technically confined in his own body and has no methods of communication with the world. Brain-computer interface (BCI) has opened up a whole new …

The Viability Of Organ Printing, Estie Schick

The Science Journal of the Lander College of Arts and Sciences

Organ printing is an emerging technology that can potentially replace the need for human organ transplants altogether. Organ printing uses bioprinting methods to create three-dimensional biological constructs. Although it has not yet been implemented successfully, with nearly two decades of research devoted to this area, much progress has been made. This article outlines the various aspects of the organ printing process, describes both the accomplishments and challenges of bioprinting, and discusses the feasibility of bioprinting as a viable method for organ replacement.

Effect Of Traumatic Brain Injury Among U.S. Servicemembers With Amputation, Mitchell J. Rauh, Hilary J. Aralis, Ted Melcer, Caroline A. Macera, Pinata Sessoms, Jamie Bartlett, Michael R. Galarneau

Kinesiology & Sport Management Scholarship

Servicemembers with combat-related limb loss often require substantial rehabilitative care. The prevalence of traumatic brain injury (TBI), which may impair cognitive and functional abilities, among servicemembers has increased. The primary objectives of this study were to determine the frequency of TBI among servicemembers with traumatic amputation and examine whether TBI status was associated with discharge to civilian status and medical and rehabilitative service use postamputation. U.S. servicemembers who had a combat-related amputation while deployed in Iraq or Afghanistan between 2001 and 2006 were followed for 2 yr postamputation. Data collected includes injury mechanism; postinjury complications; Injury Severity Score (ISS); and …

Simulation And Control Of An Intelligent Prosthetic Knee With Biogeography-Based Optimization, George L. Thomas

Undergraduate Research Posters 2012

Traditional, passive leg prostheses for transfemoral amputees require the user to produce unnaturally large actuations in order to walk. The resulting motions can cause joint degeneration and arthritis. To avoid this, a semi-active prosthetic knee using hydraulics to store and release energy has been developed. In our work this summer, we have improved upon a previous simulation model for this leg, and we have developed preliminary valve control results in this simulation software with BBO.

The Use Of A Pylon Mounted Transducer For Investigating The Gait Of Transtibial Amputees, Justin Robert Brink

UNLV Theses, Dissertations, Professional Papers, and Capstones

Two areas of research interest in the design and use of lower limb prosthetic devices are how foot performance varies with design and how prosthesis alignment affects gait. The current study addressed both of these areas through the use of the JR3 triaxial transducer mounted at the base of the socket. The transducer is an innovative form of instrumentation that measures forces and moments at the end of the socket. Traditional measurement of gait uses a force plate buried in the floor of a gait laboratory. The study established that the transducer offers a viable means of instrumentation for amputee …

Targeted Reinnervation, Yonatan Levi Moshayev

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction of this paper: Imagine living a life where even the simplest of tasks such as eating a grape or holding an egg required intense concentration and months of training. Until recently, this was the harsh reality for people with upper limb prostheses. Currently, the most common upper limb prosthetic technology being used is body powered. These devices capture remaining shoulder movements with a harness and transfer this movement through a cable to operate the hand, wrist, or elbow. With this control method, only one joint can be operated at a time. When …

Low-Cost Prosthetic Leg For The Vida Nueva Prosthesis Clinic, Sarah M. Baker, Justin G. Lekos, Jen Van Donk, Kevin Yamauchi

Mechanical Engineering

The Piernas de Vida team partnered with the Vida Nueva Clinic of Prostheses and Orthoses in Choluteca, Honduras to design, plan, and implement a prosthetic foot that could be manufactured entirely by the technicians at the clinic in order to reduce their costs and ultimately allow them to serve more patients each year. Currently, the clinic uses a prefabricated prosthetic lower limb provided by the International Committee of the Red Cross (ICRC) which can be adapted to both transDfemoral and transDtibial patients. The team has successfully developed a foot, currently called the Layer Foot, which can be used by the …
