Distribution and cost of wheelchairs and scooters provided by Veterans Health Administration

During fiscal years 2000 and 2001, the Veterans Health Administration provided veterans with more than 131,000 power wheelchairs and medical scooters at a cost of $109 million. This national study is the first to investigate Veterans Health Administration costs in providing wheelchairs and scooters and to compare regional prescription patterns. With a retrospective design, we used descriptive methods to analyze fiscal years 2000 and 2001 National Prosthetics Patient Database data (cleaned data set of 113,724 records). Wheelchairs were categorized by function, weight, and adjustability options for meeting individual needs (e.g., axle position, camber, position of wheels, tilt, and recline options). Results displayed a cost distribution that was negatively skewed by low-cost accessories coded as wheelchairs. Of the standard manual wheelchairs, 3.5% could be considered beyond the customary cost. Regionally, 71% to 86% of all wheelchairs provided were manual wheelchairs, 5% to 11% were power wheelchairs, and 5% to 20% were scooters. The considerable variation found in the types of wheelchairs and scooters provided across Veterans Integrated Service Networks may indicate a need for evidence-based prescription guidelines and clinician training in wheeled-mobility technologies.

Satisfaction with technological equipment in individuals with tetraplegia following spinal cord injury

Saturday, August 29th, 2009


Satisfaction with technological equipment in individuals with tetraplegia following spinal cord injury

OBJECTIVE: To measure the acquisition, use and satisfaction with high technology equipment by spinal cord injured tetraplegic subjects. DESIGN AND SETTING: A questionnaire was mailed to 102 tetraplegic subjects who were hospitalised in the rehabilitation center of Kerpape (Ploemeur, France) between 1998 and 2004, and 59 subjects responded. The questionnaire asked about the use of telephones, computers, wheelchairs and environmental controls at home. RESULTS: When a piece of equipment was acquired, it was very often used. Patient satisfaction with equipment was 79.3%. Home phones and mobile phones were often used with options such as hands-free devices (78 and 59% respectively). A total of 64.4% of subjects acquired a manual wheelchair and 61% a power wheelchair. The most commonly acquired options on the power wheelchairs were the powered recline (73,7%) and tilt (71,1%) systems. All options were used but all were more desired than acquired. A total of 27.1% of subjects desired a pushrim-activated handicap scooters, but only 15.3% had acquired one; 695% of subjects had a computer. Communication was the first use for the computer (82.5%); 49.2% of subjects had acquired an environmental control system, but 20% desired one. The first reason for lack of acquisition was financial difficulties but also accessibility and information problems. The factor that influenced the acquisition and need for equipment was the degree of spinal cord injury. No other factor reduced patient satisfaction with equipment. CONCLUSION: Patients were satisfied with the equipment they acquired. But their needs, especially wheelchair options and environmental control systems, were not satisfied.

The smart wheelchair component system

Thursday, August 20th, 2009


The smart wheelchair component system

While the needs of many individuals with disabilities can be satisfied with power wheelchairs, some members of the disabled community find it difficult or impossible to operate a standard medicare power wheelchairs. To accommodate this population, several researchers have used technologies originally developed for mobile robots to create “smart wheelchairs” that reduce the physical, perceptual, and cognitive skills necessary to operate a power wheelchair. We are developing a Smart Wheelchair Component System (SWCS) that can be added to a variety of commercial power wheelchairs with minimal modification. This paper describes the design of a prototype of the SWCS, which has been evaluated on wheelchairs from four different manufacturers.

Perceptions of power mobility use and safety within residential facilities

Wednesday, August 19th, 2009


Perceptions of power mobility use and safety within residential facilities

BACKGROUND: power wheelchairs and medical scooters enhance quality of life by enabling occupation, improving self-esteem and facilitating social interaction. Despite these benefits, the risks associated with power mobility use raise serious concerns in residential facilities. PURPOSE: As there is no gold standard to assess when a client is unsafe, a two-phase study was conducted to develop client-centred guidelines for power mobility use. METHOD: In the first phase of the study, presented here, 18 in-depth, qualitative interviews were conducted with a variety of stakeholders, including power mobility users, other residents, staff and family members. RESULTS: A thematic analysis of the interviews revealed four main themes: 1) the meaning of power mobility, 2) learning the rules of the road, 3) red flags: concerns about safety, and 4) solutions. PRACTICE IMPLICATIONS: Given the importance of power mobility, safety measures need to address issues of mobility and safety for power mobility drivers and those around them.

Advancements in power wheelchair joystick technology: Effects of isometric joysticks and signal conditioning on driving performance

OBJECTIVE: An estimated 125,000 Americans with movement disorders that preclude independent mobility in a power wheelchairs and handicap scooters could benefit from improved control devices. We developed variable gain algorithm (VGA) software for our isometric joystick (IJ) that allows it to emulate a commercially available motion-sensing joystick (MSJ) in performance but retain the unique customizable features of an isometric control. Force sensing algorithm (FSA) software allowed the IJ to function as a simple isometric device. DESIGN: Using a Fitts’ Law paradigm, we compared driving performance with floor targets using a standard MSJ and an IJ with both FSA and VGA software in 11 electric power wheelchair users with a variety of impairments. Outcome measures were reaction time (RT), movement time (MT), and driving accuracy (DA). RESULTS: The IJ with FSA had a significantly shorter RT than the MSJ (P < 0.0020). The IJ with FSA had a significantly longer MT than the MSJ to far targets (P < 0.0159). No differences were found between the IJ with VGA and the MSJ with respect to RT or MT. No differences in DA were found among any of the joysticks. CONCLUSIONS: VGA software allowed the IJ to function similarly to the MSJ with respect to RT, MT, and DA.

The intention of a business building business credit card is to simplify the administration of your company. Here are three ways it can benefit you:

1. It can help when employees need to buy products or services for the company. It would be too complicated to give them determined amounts of money and maintaining a control of how much they actually spent.

2. It is invaluable when your customers wish to pay with a business line of credit card. It is much simpler for your administrative process to have a business credit card which brings a series of services that can be linked to your sales process, thus, reducing bureaucracy and unproductive costs.

Reliability and validity of the power-mobility community driving assessment

Sunday, August 9th, 2009


Reliability and validity of the power-mobility community driving assessment

The Power-Mobility Community Driving Assessment (PCDA) is a performance-based measure designed to assess driving performance of individuals using power wheelchairs or handicap scooters in community environments. This article reports the results of pilot testing and an evaluation of the assessment’s reliability and validity. Pilot testing was conducted with a random selection of Canadian occupational therapists working in the area of mobility. Although the response rate was very low, feedback confirmed the utility of the measure and contributed to one substantive scoring revision. Reliability and validity testing was conducted with a sample of 34 drivers. Internal consistency results were positive. Interrater reliability was fair to high but limited by the lack of variability in the scores. Construct validity hypotheses were tested on the relationships between PCDA scores and vision, perception, cognition, and environmental accessibility. Results indicated no relationships between the PCDA and perceptual and cognitive function and only a weak trend for a relationship with environmental accessibility. Concurrent validity was established: PCDA scores were positively associated with the judgments of therapists familiar with the driving performance of participants. In summary, the PCDA has moderate to good reliability, and content and concurrent validity results were found. More research is needed, particularly on the underlying constructs of successful driving performance. At this point, rehabilitation professionals and their clients are urged to use this assessment to establish driving performance rather than relying on assessments of perception, cognition, or environmental accessibility to predetermine whether someone will receive power mobility. Clinicians may find this a useful tool to identify where clients are able to drive safely in community settings, to identify specific learning needs, and, through those, to promote independent living for drivers of power-mobility devices.

Business Credit

In those days you had to pay the entire balance within every statement which meant it allowed you to use the business line of credit card for a determined amount of time until you got the bank statement. The question of 0 interest building business credit card did not even arise as there was not a lot of business line of credit really given back then.

Power wheelchair range testing and energy consumption during fatigue testing

Saturday, August 1st, 2009


Power wheelchair range testing and energy consumption during fatigue testing

The range of a power wheelchairs and medicare power wheelchairs depends on many factors including: battery type, battery state, wheelchair/rider weight, terrain, the efficiency of the drive train, and driving behavior. The purpose of this study was to evaluate the feasibility of three methods of estimating power wheelchair range. Another significant purpose was to compare the current draw on pavement to current draw on an International Standards Organization (ISO) Double Drum tester at one m/sec. Tests were performed on seven different power wheelchairs unloaded, and loaded with an ISO 100 kg test dummy. Each chair was configured according to the manufacturer’s specifications, and tires were properly inflated. Experienced test technicians were used for the tennis court tests, and treadmill tests. An ISO 100 kg test dummy was used for the ISO Double Drum test. Energy consumption was measured over a distance of 1500 m for each of the three test conditions. The rolling surface was level in all cases. Repeated measure analysis of variance (ANOVA) revealed a significant difference (p = 0.0001) between the predicted range at maximum speed for the three tests. Post hoc analysis demonstrated a significant difference (p < 0.01) in estimated range at maximum speed between the Double Drum test and the treadmill test, as well as between the Double Drum test and the tennis court test. Our results indicate no significant difference (p > 0.05) between the predicted range at maximal speed between the treadmill and tennis court tests. A simple relationship does not exist between the results of range testing with the Double Drum tester and the tennis court. An alternative would be to permit the use of a treadmill for range testing as simple relationships between all pertinent treadmill and tennis court range data were found. For the Double Drum tester used, the current demand is higher than under normal usage. This presents a problem as current is related to load torque in a power wheelchair. Hence, the Double Drum tester friction must be reduced. The predicted range for the tennis court test at maximum speed ranges from a low of 23.6 km to a high of 57.7 km. The range of the power wheelchair can be improved by the use of wet lead acid batteries in place of gel lead acid batteries.

BBQ FACTS: Pit Roasting

Pit roasting is cooking best bbq sauce meat in a large, level hole dug in the earth. A hardwood bbq sauce recipe fire is built in the pit, requiring wood equal to about 2 times the volume of the pit. The hardwood is allowed to burn until the wood reduces and the pit is half filled with burning coals. This can require 4 to 6 hours burning time.
