Questions for Lab Activity 2.1 ________________________________________________________________________

Part I

1. Consider each of the three objects described in the next section. First, describe how that object has been scaled or adapted compared with the object or surface for able-bodied users.
Movable Step: The step acts as a halfway point so the person using it doesn’t have to lift their legs up so high to get over the regular step. The step adds more stability to the person and the non-slip coating prevents slipping and adds to balance.
Vertical Tracks: This object allows people who may not be strong enough to grip the lid of the jar to open it. The tracks provide a stronger grip to the jar and it becomes easier to open.
Round Scoop Dish: The back of the dish is higher than the rest of the dish to prevent food from spilling off the plate. If someone who can’t eat independently used a dish without the back food might fall off.

2. Describe how the object might be used and for what types of disabilities. That is, what action does the object afford a user that a regular object or surface would not afford someone with a certain disability?
Moveable Step: The step can be used for the elderly who do not have as much flexibility and are not as stable on their feet. It aids them in their range of motion by acting as a halfway point and a shorter distance over a step.
Vertical Tracks: This can aid elderly people as well as people who may have suffered a stroke. This can also aid people with limited motor control. It helps them to get a stronger grip on the jar so they can open it.
Round Scoop Dish: This design can help people, who may have lost an arm or have limited motor control, eat more independently. The tall back of the dish prevents food from spilling.


1. The first object is a movable step only 3 in. high. It is covered with a slip-resistant rubber mat and can be placed in front of the doorway to one’s house.

2. The second object consists of two vertical tracks (walls) attached to a nonslip base. The tracks are positioned to form a V so that jars of different sizes can be wedged between the tracks that hold the lid securely.

3. The last object, called a round scoop dish, is a plastic dish with a regular rim in the front. The rim on the sides gets gradually higher until it is several inches high on the back of the dish and slightly curves back over the dish.

Part II

1. Identify two other pieces of equipment that afford someone with a disability an action otherwise not possible. You might list equipment used by someone you know who has a disability, or you can search the Internet using the term adaptive equipment. Shower Chairs Patient Lifts

2. Describe how each object or surface is body scaled or adapted.
The shower chair allows someone to sit down, if they can’t stand, and take a shower. It has wheels so you can easily move them to the shower.
The patient lift aids people who are not strong enough to get into bed on their own. It wraps around the person and lifts them into bed.

3. Describe how each object might be used and what types of disabilities it is meant to address. Shower Chair: I used this a lot when I worked with kids that have Muscular dystrophy. They can’t do anything on their own so you pick them up and put them in the chair to give them a shower. Patient lift: This can be used for heavier people that you can’t pick up and put into bed. It can be used for someone who is paralyzed or has a muscular disease.

Final Question

How does the notion of scaling or adapting objects and surfaces to afford certain actions fit into the perception-action approach or perspective?
The perception-action approach involves the changing relationship between habitats. The purpose for adapting an object is to aid the person so that they are able to complete everyday tasks independently or just to make it a little easier for them.

...1. Difference between prospective validation, retrospective validation and revalidation. Prospective Validation * Carried out during the development stage by means of a risk analysis of the production process, which is broken down into individual steps * These are then evaluated on the basis of past experience to determine whether they might lead to critical situations * Where possible critical situations are identified, the risk is evaluated, the potential causes are investigated and assessed for probability and extent, the trial plans are drawn up, and the priorities set. * The trials are then performed and evaluated, and an overall assessment is made * If, at the end, the results are acceptable, the process is satisfactory. Unsatisfactory processes must be modified and improved until a validation exercise proves to be satisfactory. * This form of validation is essential in order to limit the risk of erors occurring on the production scale, eg. In the preparation of injectable products. Retrospective Validation * Retrospective Validation involves the examination of past experience of production on the assumption that composition, procedures, and equipment remain unchanged * Such experience and the results of in-process and final control tests are then evaluated * Recorded difficulties and failures in production are analyzed to determine the limits of process parameters. * Retrospective Validation is obviously not a quality......

...Technology and Health Care 19 (2011) 483–495 DOI 10.3233/THC-2011-0646 IOS Press 483 Rehabilitation Engineering Rehabilitation robotics Marko Munih and Tadej Bajd∗ Faculty of Electrical Engineering, University of Ljubljana, Slovenia Abstract. The paper presents the background, main achievements and components of rehabilitation robotics in a simple way, using non-technical terms. The introductory part looks at the development of robotic approaches in the rehabilitation of neurological patients and outlines the principles of robotic device interactions with patients. There follows a section on virtual reality in rehabilitation. Hapticity and interaction between robot and human are presented in order to understand the added value of robotics that cannot be exploited in other devices. The importance of passive exercise and active tasks is then discussed using the results of various clinical trials, followed by the place of upper and lower extremity robotic devices in rehabilitation practice. The closing section refers to the general importance of measurements in this area and stresses quantitative measurements as one of the advantages in using robotic devices. Keywords: Robot, haptic interface, virtual reality, measurement 1. Introduction The application of robotic approaches in neurological patient rehabilitation was introduced almost two decades ago [1]. Even though the number of robotic rehabilitation systems is large, the number of clinical trials remains quite...

...Rehabilitation of Acromioclavicular Joint Separations: Operative and Nonoperative Considerations Mark P. Cote, PT, DPTa, Karen E. Wojcik, MSPT, ATCb, Gregg Gomlinski, MSPT, CSCSb, Augustus D. Mazzocca, MS, MDa,* Acromioclavicular joint (AC) separations are one of the most common injuries seen in orthopedic and sports medicine practices, accounting for 9% of all injuries to the shoulder girdle.1–3 Various operative and nonoperative treatment schemes have been described for the management of AC joint injuries.4–33 Although considerable controversy exists over the efficacy of surgical reconstruction versus nonoperative intervention for grade III type injuries, grade I and II separations seem to respond favorably to conservative management. Conversely, grades IV, V, and VI often require surgical reconstruction. Regardless of the type of injury, rehabilitation as a part of conservative management and postoperative care plays an important role in the management of these injuries. This article presents the authors’ rehabilitation approach to treatment of acromioclavicular separations pre- and postoperatively. CONCEPTUAL FRAMEWORK To provide instruction and insight for rehabilitation clinicians, protocols are often provided for a specific injury or procedure. A protocol is a system of rules or procedures for a given situation. Although intended to be informative, protocols often result in a restrictive list of exercises and arbitrary time frames that a......

Ben Kibler TENNIS RECOVERY A Comprehensive Review of the Research A United States Tennis Association Sport Science Committee Project Editors: Mark S. Kovacs, PhD Todd S. Ellenbecker, DPT W. Ben Kibler, MD Introduction In the last two decades, physical training and competitive opportunities have increased dramatically in junior, collegiate and professional tennis. This arose due to a multitude of factors, but much of it has stemmed from an increase in knowledge and understanding of scientifically based training programs focused on improving performance. As this focus on performance has increased, the area of recovery has received relatively limited focus. Recovery is a multi-faceted paradigm focusing on recovery from training—session to session, day to day and week to week. Recovery is also vitally important during training as well as in competition between matches and between days during multi-day tournaments. As more information is needed in the area of tennis specific recovery, the Sport Science Committee of the United States Tennis Association (USTA) sponsored an extensive......
