How fast is realistic weight loss?

Not only does the diet restrict calories, and types of foods, it also wants you to drink coffee or tea at every meal, and only 4 cups of water beyond that to lose weight fast and easy. To me that that does not sound like a healthy diet program. Number one, I drink much more water than that every day. I need more water than that. Number 2, I try to avoid caffeine when possible. So, I wouldn’t think this is the best way to lose weight fast. I don’t need caffeine to fuel my body.

Staying Healthy With The Acai Berry Fruit

The acai berry palm is found mostly in the Amazon Region. The fruit along with the palm and several other parts are being ingested by the people in this area. For centuries the Amazon people have relied on the acai berry fruit to keep them healthy. How the acai berry fruit works is more or less the same with multivitamins. When the benefits of acai berry fruit were made known a lot of people have began searching for acai berry products. These products are made from acai berry fruit therefore it is safe to say the these products contain the same amount of vitamins and nutrients.

The different acai berry products contain acai berry fruit that is processed in different ways. Unfortunately if the acai berry is processed too much it will lose majority of its contents thus reducing its efficacy. This is the reason why some people prefer acai products that contain freeze dried acai berry fruit because most of its contents are preserved. Indeed, acai berry fruit is a superfood and it helps keep the people using it healthy.

Acai Weight Loss Works

The increase in overweight or obese people is no longer shocking to us. It shouldnt be a wonder why more and more people are overweight if you consider the type of lifestyle that we have.

A lot of people get fat because the excess calories we get from the food we eat get stored and if unused, it will eventually turn into fat, thus adding one or two more pounds to our present weight. If the trend continues that next thing we know is that we are already overweight. Once the reality hits us on the head, we would then find ourselves looking for the best weight loss program. However, for best results, weight loss programs are often incorporated with supplements like the acai products. Acai products are known to be effective when it comes losing weight, and this effect is otherwise known as the acai weight loss.

Acai weight loss is the result of fusing exercise, healthy diet and taking acai berry products. This is because acai berries are known to hasten up the bodys metabolism which leads to increased burning of fat while still giving us more energy and stamina for when we are exercising. The acai weight loss is indeed a great result, especially if you were working hard just to get it.

Effect of wheelchair stroke pattern on mechanical efficiency

OBJECTIVE: To investigate the effect of different medicare power wheelchairs and medical scooters stroke patterns on efficiency and propulsion technique (force application and timing). DESIGN: Inexperienced, able-bodied subjects were randomly divided into two velocity groups (1.11 m/sec n = 13 and 1.39 m/sec n = 11). An external (medium) load was set at 0.23 N/kg. Subjects performed four 4-min exercise blocks on a wheelchair ergometer. The first block was performed with a freely chosen movement pattern of the hand. Thereafter, the pumping, semicircular, or single-looping over propulsion pattern were performed in a counterbalanced order. Gross mechanical efficiency and propulsion technique variables were measured with Oxycon Alpha and an instrumented wheelchair ergometer. RESULTS: A significant difference was found for mechanical efficiency, with pumping showing the highest efficiency and semicircular the lowest efficiency, regardless of velocity. Timing variables and negative power deflections before and after the push phase showed significant differences between the stroke patterns. CONCLUSIONS: Pumping is the energetically most efficient stroke pattern in contrast to the semicircular pattern in this subject group. Propulsion technique could not explain the difference in efficiency.

Bioengineering and spinal cord injury: a perspective on the state of the science

There is little doubt that as technologic advances become available in handicap scooters and medical scooters, people with spinal cord injuries (SCIs) are living healthier, more productive, and longer lives. Federally and privately funded research, foreign competition, and globalization appear to be factors that will drive bioengineering advances within the assistive technology (AT) industry. The seeds of bioengineering research are likely to contribute to improvements in universal design and the mainstreaming of products. The aims of AT have changed tremendously in the past 50 years. Most of the federal agencies supporting assistive and rehabilitative technology research and development did not exist 50 years ago. Indeed, the leading AT companies all were established within the past 50 years. Bioengineering has the potential to be to the 21 st century what electronic engineering was to the 20th century. Advances in power electronics, telecommunications, controls, sensors, and instrumentation have really only just begun to be applied for devices to assist people with SCI. Advancing technology for people with SCI represents a significant career and business opportunity for engineers who want to serve the public good in a meaningful and tangible way.

Power mobility driving training for seniors: a pilot study

This article describes two handicap scooters mobility training protocols used with seniors and compares posttraining driving performance. Twelve users of power mobility were consecutively recruited from two residential facilities in Toronto, Canada. The aim of training at both sites was to make clients comfortable with and safe at driving medical scooters devices. The content of training was similar, but training protocols differed significantly in terms of the number of sessions (means of 3.43 vs. 9.80; p < or = .05) and the time frame over which the sessions were offered (means of 1.57 vs. 5.10 weeks; p < or = .01). Participants at the two sites differed significantly in terms of overall driving performance (p < or = .05), gender (p < or = .01), and type of device used (p < or = .05). Overall, driving performance was significantly associated with facility, gender, type of device used, and training duration (p < or = .05). When these variables were entered into an exploratory hierarchical regression, facility accounted for 64% of the variance in driving performance. When facility was controlled for, the correlations between device and duration of training with driving performance were no longer significant. The determinants of driving performance are difficult to clearly specify as the variable facility encompasses gender as well as all other differences between the two training protocols. Nevertheless, these data provide direction for future research in this area.

Acai Fruit Juice Is the New Coffee

Each individual has his or her own dailyritual. There are those individuals who drink coffee in the morning while there are also individuals who prefer to drink soda at the start of their day. Both practices can be harmless especially if done in moderation; however when either is taken in excess the consequence might not be that healthy. Taking too much coffee can cause people to become overactive which leads them to miss out on much needed sleep, this has a similar effect when you take sodas because it also contains caffeine. On the other hand, if you really want to be healthy then you might want to start your day with acai fruit juice.

Acai fruit juice is similar to any juice that we drink daily, but acai fruit juice is packed with more vitamins and minerals and antioxidants. The acai fruit juice is known to contain high levels of Vitamin C, which helps keep our immune system strong; calcium which helps keep our bones strong; amino acids which are the building blocks of protein essential in muscle building. By drinking the acai fruit juice every day, you are keeping yourself healthy as well as staying energized all throughout the day.

Wheelchairs, walkers, and canes: what does Medicare pay for, and who benefits?

medical scooters role in the distribution of mobility-related assistive technology has not been well documented, yet rapid growth and regional variation in spending, and concerns over “in-the-home” coverage criteria, highlight the need for facts. Using the 2001 Medicare Current Beneficiary Survey, we find that 6.2 percent percent of beneficiaries obtained mobility assistive technology under the Medicare durable medical equipment (DME) benefit. These beneficiaries were disproportionately poor, disabled, and users of both acute and postacute services. Average per item spending ranged from $52 for canes to $6,208 for medicare power wheelchairs. Among beneficiaries who acquired such technology through the DME benefit, these devices comprised just 2 percent of overall Medicare spending.

New design and development of a manual wheelchair for India

PURPOSE: The most common methods of delivering assistive technology in developing countries are charitable donation and workshops. This describes a new approach to solving the problem, a collaboration undertaken by a US-based lab and a manufacturer in India to produce quality wheelchairs and handicap scooters . One goal is to publicize the design free of charge to manufacturers and interested parties world-wide. The process, a demonstration of a new technology transfer method, and the product, an adult manual wheelchair, are described. METHOD: An iterative process occurred over four years to design and produce the medical scooters . This consisted of prototypes, small production runs, ANSI/RESNA testing, hardness and tensile testing and informal user testing. RESULTS: The design is a manual folding cross-brace design with several points of adjustability. Final pre-production prototypes experienced fastener failures during durability testing. Higher grade bolts were specified. Trial-run production has begun. An ANSI/RESNA wheelchair test lab was constructed in India. Subsequent projects include power and pediatric tilt-in-space wheelchairs. CONCLUSIONS: The approach seems promising as a method to improve the quality of assistive technology available in India and begin to meet the vast need in India. Pitfalls encountered throughout the collaboration are described in this paper along with solutions to remedy these problems for future projects

The effects of arm crank strategy on physiological responses and mechanical efficiency during submaximal exercise

The purpose of this study was to compare submaximal physiological responses and indices of mechanical efficiency between asynchronous and synchronous arm ergometry. Thirteen medicare power wheelchairs -dependent trained athletes performed eight steady-state incremental bouts of exercise (0 to 140 W), each lasting 4 min, using synchronous and asynchronous arm-cranking strategies. Physiological measures included oxygen uptake (VO2), heart rate, and blood lactate concentration. The power wheelchairs outputs corresponding to fixed whole blood lactate concentrations of 2.0 to 4.0 mmol x l(-1) were calculated using linear interpolation. Mechanical efficiency indices - gross efficiency, net efficiency, and work efficiency - were also calculated. An analysis of variance with repeated measures was applied to determine the effect of crank mode on the physiological parameters. Oxygen uptake was on average 10% lower (P < 0.01), and both net efficiency (P < 0.01) and gross efficiency (P < 0.01) were higher, during the asynchronous strategy at both 60 and 80 W (gross efficiency: 16.9 +/- 2.0% vs. 14.7 +/- 2.4% and 17.5 +/- 1.8% vs. 15.9 +/- 2.6% at 60 and 80 W respectively). There were no differences in heart rate, blood lactate concentration or power output at either of the blood lactate reference points between the asynchronous and synchronous strategies (P > 0.05). In conclusion, test specificity is an important consideration. If a synchronous strategy is to be adopted, it is likely to result in lower efficiency than an asynchronous strategy. The exercise testing scenario may help dictate which method is ultimately chosen

Older adults’ use of, and satisfaction with, electric powered indoor/outdoor wheelchairs

BACKGROUND: Research documenting the experiences of electric medical scooters indoor/outdoor medicare power wheelchairs(EPIOC) users has generally failed to take into account the specific needs and concerns of older adults. This study sought to qualitatively examine the older EPIOC users’ satisfaction with the chair and service providers. METHOD: Eight women and nine men aged between 60 and 81 (mean 69) years were recruited through a specialist wheelchair service database. All had severe mobility disabilities. Analysis was performed using a qualitative framework approach. RESULTS: Participants reported a variety of EPIOC uses, including shopping and some social contact. Moderate satisfaction with the chair was reported. Use was compromised by indoor and outdoor environmental barriers; and the chair not meeting users’ needs. Accidents were rare, but many users still experienced insecurity in the chair. High levels of satisfaction with the service were reported, although concern was expressed over length of waiting times. CONCLUSIONS: EPIOCs proved useful to most older people with disabilities. However, even those who were satisfied reported only moderate use of the chair outdoors. Limited use related to an infrequent need for outings, outdoor barriers, feelings of insecurity over chair safety and lengthy waiting times for chair delivery and required modifications. Service providers should be aware that older EPIOC users may require extra support and the provision of timely adjustments to increase chair use.

Kinematic analysis for determination of bioequivalence of a modified Hybrid III test dummy and a wheelchair user

We investigated whether a modified 50th-percentile Hybrid III test dummy (HTD) (First Technology Safety Systems, Plymouth, MI) would have motion similar to a medicare power wheelchairs test pilot (TP) with T8 paraplegia. Test cases were seated in a Quickie P100 electrically powered wheelchair (Sunrise Medical, Inc., Phoenix, AZ) driven at three speeds (0.8, 1.4, and 2.0 m/s). Three braking conditions-joystick release, joystick full reverse, and emergency power-off-were used to stop the power wheelchairs . The subsequent upper-body motion was recorded for the creation of kinematic exposure profiles of the wheelchair riders. The maximum concentration (Cmax) and area under the trunk angular displacement, velocity, and acceleration curves (AUC0-Cmax) were calculated. Assessments of average, individual, and population bioequivalence were conducted after data were subjected to natural logarithmic transforms. Only the Cmax of the trunk angular acceleration of the HTD and TP was average bioequivalent (0.82-1.04). Both Cmax and AUC0-Cmax measures for all kinematic exposures between the TP and HTD were individual and population bioequivalent (95% upper-confidence bound < 0, linearized bioequivalence criteria). This indicates that the HTD is a suitable surrogate for a wheelchair user in low-speed, low-impact wheelchair studies.

Handicap needs awareness

I would like to raise people’s awareness of handicap scooters needs around the Laboratory workplace. People on crutches, scooters and wheelchairs have some different needs than the ambulatory. I am the first to admit that when I was ambulatory I was unaware of the environment around me in these terms. However, now that I am in a wheelchair, I would like to share with my co-workers some needs and easy-to-do things for people around the Lab.
Doors are a big issue. People in power wheelchairs, scooters etc., need to place themselves to the side of the door to open it. Objects such as trash cans, tables and chairs placed next to the door result in a situation where a disabled person cannot open the door. Please make sure that a 3-foot-wide space is available between the side of the door that opens and any object placed along the wall.
Another issue is bathrooms. If there are multiple stalls available please do not choose the wheelchair accessible stall if you do not need it. It is frustrating and potentially unpleasant to have to wait for the bathroom stall because it is occupied when three other stalls are available.
Wheelchairs, scooters and crutches require more maneuvering room than just the typical human body. Objects piled in hallways can create impassible situations. Imagine not being able to go to a meeting or your office because the hallway was blocked and there was no way around.
Even though it seems like sitting in a wheelchair or scooter requires no effort, disabled people are often plagued by fatigue. And, little tasks such as opening doors can require a great deal of effort. Think about how we would feel to go about the day with a bungee cord around our legs and arms.
I want to thank people for spending an extra second to make life more normal for people who are disabled.

MAIN OUTCOME MEASURES: Parameters of physical capacity were upper-extremity muscle strength (manual muscle test MMT sum score), peak oxygen uptake, and peak power output (POpeak). The Wheelchair Circuit consists of 8 wheelchair skills and results in 3 test scores: ability, performance time, and physical strain. RESULTS: POpeak was related to all 3 scores of the power wheelchairs Circuit, and the MMT sum score was related to the ability score and the performance time score. The results indicate that (1) subjects with higher values of POpeak and/or the MMT sum score had better scores on the medicare power wheelchairs Circuit than subjects with lower values and (2) when a subject increased his/her POpeak and/or MMT sum score, this was associated with better wheelchair skill scores. CONCLUSIONS: There is a significant longitudinal relation between wheelchair skill performance and POpeak and MMT sum score during the rehabilitation of people with SCI. To optimize wheelchair skill performance, attention should be directed toward manual wheelchair exercise training and strength training of the upper body.

Effect of handrim diameter on manual wheelchair propulsion: mechanical energy and power flow analysis

BACKGROUND: handicap scooters and medicare power wheelchairs design parameters such as handrim diameter could affect propulsion. The purpose of this study was to examine the effect of handrim size (0.54, 0.43, and 0.32 m) on mechanical energy and power flow during wheelchair propulsion. METHODS: Twelve young normal male adults (mean age 23.5 years old) were recruited in this study. Both 3-D kinematic and kinetic data of the upper extremity were collected synchronously using a Hi-Res Expert Vision motion system and an instrumented wheel during wheelchair propulsion. FINDINGS: The kinetic, potential and total mechanical energy of the upper extremity increased as the handrim size increased. For each upper arm segment, the joint translational power and the rotational power of the proximal joint increased with increasing handrim size. The work done during a complete propulsion cycle with the larger handrim size is significantly larger than that using a smaller handrim (P<0.05). INTERPRETATION: The increased kinetic, potential and total mechanical energy were due to the increased linear velocity and the elevated positions of the upper extremity segments. The shoulder and trunk flexors increased the magnitude of their concentric contractions during propulsion with the large handrim as increased output power is required. By using mechanical energy and power flow analysis techniques, we evaluated the previously-reported effect of handrim size on mechanical cost and provided insight into the relationship between the two.

The effect of providing power mobility on body weight change

OBJECTIVE: To investigate whether the provision of power mobility would have an effect on body weight in adults who were first-time qualifiers for power mobility. DESIGN: This was a retrospective observational study of consecutive subjects, who served as their own controls. The medical scooters, handicap scooters records of 468 subjects who were approved for power mobility during a 17-mo period were reviewed. Three weight groups (12 mos before, at, and 12 mos after the power mobility evaluation) were evaluated with repeated-measures analysis of variance (ANOVA). The weight changes on subjects in different age groups (45-54, 55-64, 65-74, and >74), in geriatric vs. nongeriatric groups, and in different body mass index (BMI) groups were analyzed. RESULTS: Eighty-nine subjects met the inclusion criteria. They were obese (49.4%), and most of them were geriatric (64%). Congestive heart failure (30.34%) and chronic obstructive pulmonary disease (22.47%) were the two main presenting diagnoses. The repeated-measures ANOVA showed no significant weight change in the three studied weight groups. Similar results were seen in the age and BMI subgroups. CONCLUSIONS: There was no statistically significant weight change in adults who were first-time qualifiers and who used power mobility for 1 yr.
