The Effect Of A Powered Ankle Foot Orthosis On Walking In A Stroke Subject: A Case Study, Ali Pourghasem, Ismail Ebrahimi Takamjani, Mohammad Taghi Karimi, Mohammad Kamali, Mohammad Jannesari, Iman Salafian

Department of Mechanical and Materials Engineering: Faculty Publications

[Purpose] Standing and walking are impaired in stroke patients. Therefore, assisted devices are required to restore their walking abilities. The ankle foot orthosis with an external powered source is a new type of orthosis. The aim of this study was to evaluate the performance of a powered ankle foot orthosis compared with unpowered orthoses in a stroke patient.

[Subjects and Methods] A single stroke subject participated in this study. The subject was fitted with three types of ankle foot orthosis (powered, posterior leg spring, and carbon ankle foot orthoses). He was asked to walk with and without the three types …

Predicting Walking Ability And Prosthetic Candidacy Following Lower Extremity Amputation: Systematic Review, Treatment Pathway And Algorithm, Scott Love

Student Dissertations

Purpose: The purpose of this study is a systematic review (SR) of existing literature to examine characteristics of persons with amputation which predict walking ability and prosthetic candidacy following lower extremity amputation (LEA). The identification, synthesis and summary of this evidence could assist in developing clinical practice guidelines, including a physical rehabilitation treatment pathway and a clinical algorithm. The importance of this project is the establishment to further develop evidence based LEA clinical practice guidelines. This evidence will assist the healthcare team in decision making, specifically considering evidence and patient-centric predictive characteristics.

Background: Currently, there is no multi-disciplinary physical …

Self-Perceptions Of Disability And Impairment In An Indian Prosthetic Population Using Jaipur Foot Technology, Litany Esguerra

Independent Study Project (ISP) Collection

Twenty-nine first time and repeat prosthetic users were interviewed over a period of three weeks to determine how they perceived their own disability at Bhagwan Mahaveer Viklang Sahayata Samiti, or Jaipur Foot, located in Jaipur, India. The questions delineated different aspects of people’s disabilities and impairment, and asked a multitude of questions regarding social, economic, political, and other contexts, influenced by the conceptual framework of the International Classification of Functioning (ICF). The study analyzed all of the factors as specified by the questionnaire and found that many varying trends over all types of prosthetic users. The study also used the …

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 …
