Assistive Multi-Purpose Mobility Device with Folding Temporary Seat Assistive Multi-Purpose Mobility Device with Folding Temporary Seat A Major Qualifying Project Proposal Submitted to the Faculty of WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science by _________________________ Xinping Deng _________________________ Daniel Haley _________________________ Taylor Roseen Date: 4/30/15 Approved: ______________________________ Professor Allen H. Hoffman, Co-Advisor ______________________________ Professor Holly K. Ault, Co-Advisor Abstract Crutches and canes are widely used around the world as a means of providing stability and support for those who need them; the elderly population in particular utilizes these devices the most. There are numerous products on the market that attempt to add a seat to the crutch or cane in an effort to alleviate the stress of standing for too long. However, these products are oftentimes too cumbersome, heavy, or just simply unsafe. The goal of this project is to design and build a device that can be used as either a crutch or a cane that gives stability and helps support the weight of the user while standing and walking, additionally offering the ability for the user to rest comfortably and safely in a seated position when necessary. A first generation prototype was successfully manufactured using an existing forearm crutch and machined aluminum and steel components. The prototype underwent load and dimension tests in addition to students conducting overall usability tests. i Table of Contents Abstract

  • Tips for Communicating with People with Disabilities
    Tips for Communicating with People with Disabilities One important consideration for communicating with people with disabilities (PWD) is updating language to avoid terms and labels that could be offensive. A good rule of thumb is to use “person-first” language, which places the person before their disability and avoids using a person’s disability as a way to refer to them. Disability Out-Dated Language Respectful Language Blind or Visually Dumb, Invalid Blind/Visually Impaired, Person who Impairment is blind/visually impaired Deaf or Hard-of-Hearing Invalid, Deaf-and-Dumb, Deaf or Hard-of-hearing, Person who Deaf-Mute is deaf or hard of hearing Speech/Communication Dumb, “One who talks Person with a speech / communication Disability bad" disability Learning Disability Retarded, Slow, Brain- Learning disability, Cognitive Damaged, “Special ed” disability, Person with a learning or cognitive disability Mental Health Disability Hyper-sensitive, Psycho, Person with a psychiatric disability, Crazy, Insane, Wacko, Person with a mental health disability Nuts Mobility/Physical Handicapped, Physically Wheelchair user, Physically disabled, Disability Challenged, “Special,” Person with a mobility or physical Deformed, Cripple, Gimp, disability Spastic, Spaz, Wheelchair- bound, Lame Emotional Disability Emotionally disturbed Emotionally disabled, Person with an emotional disability Cognitive Disability Retard, Mentally retarded, Cognitively/Developmentally “Special ed” disabled, Person with a cognitive/developmental disability Short Stature, Little Dwarf, Midget Someone of short stature, Little Person Person Health Conditions Victim, Someone “stricken Survivor, Someone “living with” a with” a disability (i.e. specific disability (i.e. “someone “someone stricken with living with cancer or AIDS”) cancer” or “an AIDS victim”) NYLN & KASA1 General Tips Use a normal volume and tone when speaking to persons with disabilities.

  • 2017 Ada Update on Service Animal Rules
    2017 ADA UPDATE ON SERVICE ANIMAL RULES The California Hotel & Lodging Association receives many questions regarding the rights and obligations of lodging establishments with respect to service animals. This document contains CHLA’s updated discussion of this topic. First, there has been a significant change regarding California law related to service animals. This change, which is discussed below, will make it easier for lodging operators to deal with guests who claim that their pets are service animals. Here are the basics of California law as it relates to service animals: • There was a time when the California Department of Fair Employment and Housing, which administers California’s Fair Employment and Housing Act (Act), took the position that the Act applied to the lodging industry. At that time, there was concern that lodging operators would have to comply with the more stringent requirements of the Act: (1) it is not limited to dogs— depending on the circumstances, the FEHA protects other types of animals and treats them as service animals; and (2) it provides protections for people who use “comfort” and “companion” animals. Contrary to the Department’s earlier position, however, CHLA was recently advised that the Act only applies to homes, condos, and apartments, and that it does not apply to hotels! • It is important for lodging operators to bear in mind that although the 2011 revisions to the ADA rules regarding service animals expressly state that (1) only dogs qualify as service animals,1 and that (2) “comfort” and “companion” dogs are not service animals,2 if a local jurisdiction in California has broader, more stringent rules than the ADA, the local rules must be complied with.

    Review Sensor-Based Assistive Devices for Visually-Impaired People: Current Status, Challenges, and Future Directions Wafa Elmannai and Khaled Elleithy * Department of Computer Science and Engineering, University of Bridgeport, Bridgeport, CT 06604, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-203-576-4703 Academic Editor: Panicos Kyriacou Received: 23 January 2017; Accepted: 1 March 2017; Published: 10 March 2017 Abstract: The World Health Organization (WHO) reported that there are 285 million visually- impaired people worldwide. Among these individuals, there are 39 million who are totally blind. There have been several systems designed to support visually-impaired people and to improve the quality of their lives. Unfortunately, most of these systems are limited in their capabilities. In this paper, we present a comparative survey of the wearable and portable assistive devices for visually- impaired people in order to show the progress in assistive technology for this group of people. Thus, the contribution of this literature survey is to discuss in detail the most significant devices that are presented in the literature to assist this population and highlight the improvements, advantages, disadvantages, and accuracy. Our aim is to address and present most of the issues of these systems to pave the way for other researchers to design devices that ensure safety and independent mobility to visually-impaired people. Keywords: assistive devices; visually-impaired people; obstacles detection; navigation and orientation systems; obstacles avoidance 1. Introduction The World Health Organization (WHO) Fact reported that there are 285 million visually- impaired people worldwide.

ISSN 2321-1822 Case Report DOI: https://dx.doi.org/10.16965/ijpr.2020.144 MUSCULOSKELETAL PHYSICAL THERAPY FOR SACROILIAC JOINT PAIN Anas Alhakami*1, Mohammed Qasheesh2, Senthilkumar Cennappan Bose3. *1 Senior Musculoskeletal Physical Therapist, King Faisal Medical City for Southern Regions, Kingdom of Saudi Arabia. 2 Assistant Professor and Head-Physical Therapy, Jazan University,Kingdom of Saudi Arabia 3 Lecturer-Physical Therapy, Jazan University, Kingdom of Saudi Arabia. ABSTRACT This case report describes a clinical case of a 53 years aged male with Low Back Pain(LBP) at Sacro Iliac Joint(SIJ). Patient referred to physical therapy department with LBP over the past 3 weeks. Pain extended to posterior aspect of left thigh and worsening with prolonged standing, sitting and with stair climbing. Moreover, he found difficulty to ride his car or going from sit to stand. He had a history of road traffic accident 30 years ago that led to severe pain in his lower back area, he was a farmer as well and was working hardly more than 8 hours daily by lifting heavy objects. Patient came to the department by walking with assistive cane. By palpation, there was a local tenderness at the posterior aspect of the SIJ. Range of motion was limited by pain in lumbar flexion, extension, rotation and bilateral side bending movements. Pain scored 7 out of 10 on Numerical Pain Rating Visual Analogue Scale. Functional disability scored 19 out of 24 on Roland-Morris Disability questionnaire.
