What Is Physical Therapy and What Does a Physical Therapist Do ...

If you ask a person what they think of when they hear the words ?physical therapy? a large percentage will tell you that they think of rehabilitation therapy for patients with injuries ranging from an accident or loss of mobility to a sports injury. They also think of other patients that need rehab therapy for illnesses which relate to musculoskeletal problems and are hospitalized for these problems.A smaller percentage may tell you that they think of physical therapy as working with some kind of exercises to work the muscles similar to what a chiropractor does while another percentage does not really know what the words ?physical therapy? mean. In light of the fact that there are many preconceived notions of what physical therapy means let?s first clarify what physical therapy is before we discuss what a physical therapist does and how they can help you.

What Physical Therapy Really Means

Physical therapy involves the process of manipulating different body parts to decrease pain, improve mobility and function, and improve bodily strength to help the individual enjoy a better quality of life. Physical therapy also involves helping people prevent injuries and improve energy levels by staying physically fit.Although physical therapy includes an individual evaluation to come up with a plan for treatment,What Do Physical Therapists Do? the plan can be associated with an injury or illness or it can also consist of a plan for an ongoing health program which will help you enjoy a better quality of life by having the energy to do and enjoy more things. If you are having difficulty coming up with a long term health plan, physical therapy can be of tremendous benefit since it will be individualized to help you meet your health and fitness goals.

How a Physical Therapist Can Help

A physical therapist is highly educated and licensed to help people achieve their health and fitness goals. For this reason, a lot of people think of physical therapists as physicians who help you to overcome an injury or illness. While this is partially true you can also consult with a physical therapist to come up with a personalized program to improve and maintain health and prevent injury over the long term.Regardless if you have an injury or illness or you simply want to increase your chances of continued good health and longevity, a physical therapist will do a complete evaluation which includes reviewing the status of muscular, skeletal, neurological, cardiovascular, pulmonary, and lymphatic systems as well as any other health concerns. The physical therapist will then work closely with you to determine what needs to be done to improve your health and longevity.

A physical therapist can also help you to learn what important aspects of your health you should focus on and what some of your personal goals are for achieving good health and wellness. This saves you time because the areas you should focus on are individually designed in a program that specifically suits your needs. This takes the guesswork out of coming up with a program you may think is beneficial to your health but you do not know for sure. For example, if you have specific shoulder problems, a physical therapist can help you come up with a plan to gain more use of your shoulder through rehab therapy without risking injury. If you have arthritis, your physical therapist can help you with a plan for treatment for the area of your body which is specifically affected by the disorder.Essentially a physical therapist can help you to gain control over your health without the use of drugs. The physical therapist will get to the root of the problem and then work with you on a treatment plan until your goals are achieved for overcoming the precise health problem. If there is a health concern that requires the attention of a physician then the physical therapist will refer you to the appropriate health professional. So, physical therapy involves a lot more than rehab therapy and can significantly help you to maintain overall good health and well being for the long term.

Sony VAIO Fit 14 (SVF14A15CXB)

The Sony VAIO Fit 14 (SVF14A15CXB) ($849 list) is an almost-ultrabook. Coming in at a hair over the 21mm thickness specification, the VAIO Fit 14 is a mainstream laptop that doesn't qualify as an ultrabook, even though it shares its Intel Core i5 processor, SSD+Hard drive configuration, and quick wake from sleep capabilities with systems that meet the ultrabook spec. We surmise that Sony called it the Fit to fill a niche between its thinner ultrabooks and its larger desktop replacement laptops. Most times, system manufacturers choose to go off-spec to gain some benefit that the strict specifications can limit. Other than the inclusion of an optical drive, however, we can't seem to find a reason. The system costs as much as competing ultrabooks and performs on most benchmark tests just as well. However a couple of drawbacks emerged during testing, including a short battery life and a very uncomfortable keyboard. These downsides held the VAIO Fit 14 from gaining a better overall score in the end.

Design and Features
The VAIO Fit 14 has the hallmarks of a Sony VAIO design, with its black-brushed metal lid, embossed VAIO logo (now with chrome outline), matching palm rest, and one piece trackpad. The system measures 0.87 by 13.5 by 9.25 inches (HWD) and weighs 4.26 pounds. These are quite respectable stats for a 14-inch laptop, though the system is thicker than touch ultrabooks like the Toshiba Satellite U845t-S4165 ($799).

The center of attention on the VAIO Fit 14 is the 14-inch screen with its 1,600 by 900 resolution. This is a much higher resolution than the 1,366 by 768 resolution screen we see on run of the mill laptops in this segment like the Samsung Series 5 UltraTouch NP540U3C-A01UB ($849). While not true 1080p HD, the VAIO Fit 14's screen is sharp, clear, and bright, which is everything we expect from Sony. The 10-point touch screen is responsive, and is protected by a seamless piece of glass. The black border around the screen is necessary to give your finger an off-screen starting point for Windows 8 gestures, and on the whole the system has a pleasing aesthetic. The multi-touch trackpad is also compatible with Windows 8 gestures, so you can use either to get around in Windows and on the Internet.

The backlit keyboard has an intelligent layout, with reduced sized keys for the F1-F12 keys and the arrow keys. The only other buttons on the top of the system are the power button and the VAIO Assist button, which opens a help utility. The chiclet-style keyboard could use some help: the keys are very stiff, which let you type quickly, but the flat key tops and very shallow key travel means that the keyboard feels uncomfortable to use. While you'd be able to easily type at 60 words per minute or more, the keyboard feels uncomfortable during use, and your fingers and wrists may tire quickly. It is similar to the touch keyboard cover on the Microsoft Surface Windows 8 Pro ($999): you can use the keyboard part time quite successfully, but it will start to become uncomfortable after about ten to fifteen minutes of use. Since the built-in keyboard is one of the main reasons to buy a laptop over a slate Windows 8 tablet, we see the uncomfortable keyboard as a glaring flaw. The Sony VAIO Fit 14 comes with a utilitarian, yet unremarkable set of I/O ports. The VAIO Fit 14 has two USB 3.0 ports, HDMI, SD card reader, Ethernet, and a headset jack.

The system comes with a 750GB hard drive for storage with a 8GB cache SSD. Sony calls this setup a Hybrid Hard Drive, but essentially it's like the cache SSD plus spinning hard drive configuration common to entry level ultrabooks like the Editors' Choice Acer Aspire M5-481PT-6644 ($730). The cache drive helps these systems on day-to-day tasks (as seen by the PCMark7 scores below), as well as helping these systems wake from sleep quicker than systems that have a hard drive-only configuration. The VAIO Fit 14 took less than three seconds to wake from sleep mode, which is as fast as SSD-only systems like the Toshiba Satellite U845t-S4165. The VAIO Fit 14 comes with an optical DVD burner, which will come in handy if you want to watch programs from your DVD library or want to install older programs that came on CD or DVD.

The VAIO Fit 14 has a very good selection of multimedia content creation apps, like ArtRage Studio (a painting program that leverages the touch screen), Sony's ACID Music Studio, DVD Architect Studio, Movie Studio Platinum, and Sound Forge Audio Studio. If you don't already have these programs, they can help turn your den or dorm room into a music/video/podcasting studio. Other preloaded programs include music and photo library programs by Sony, Sociallife (a social networking aggregator), Skype, Solitaire, Minesweeper, Slacker Radio, iHeartRadio, Music Maker Jam, PlayMemories Home, VAIO Movie Creator, Intel AppUp, Hulu Plus, and Skype. It's a lot of programs that you have no say in receiving, but most of them can be useful to the creative hobbyist. The VAIO Fit 14 comes with a one-year warranty.

Performance
The VAIO Fit 14 comes with an Intel Core i5-3337U processor, 8GB of memory, and that 750GB hard drive with 8GB cache SSD. The combination of components garners the VAIO Fit 14 a very good score on the day-to-day PCMark7 benchmark test. It's not quite as fast as the SSD-powered Toshiba U845t-S4165, but it's close. Likewise, the VAIO Fit 14 comes in with very close scores with the Toshiba U845t-S4165 on the multimedia benchmark tests (Handbrake and Photoshop CS6). Taken together, this means that the VAIO Fit 14 will be a good companion to the multimedia maven, provided she can get over the uncomfortable keyboard. The 3D numbers from the VAIO Fit 14 were good, thanks to the integrated Intel HD Graphics 4000 in the Core i5 processor. You won't be able to play high-end 3D games, but you should be able to play light 3D games and browser-based games fine.

Battery life is important to laptop usage, and unfortunately the VAIO Fit 14's score of 4 hours 8 minutes on our battery rundown test is another of the system's disappointments. Systems like the Toshiba U845t-S4165 (6:17) and Acer M5-481PT-6644 (6:04) go past six hours, which means that they will be able to last most if not all of your afternoon's schedule. The VAIO Fit 14 might last the afternoon, if you lay off the social networking and let the system sleep while you're not taking notes. The battery is sealed in the chassis, so you won't have the option of carrying spare charged batteries to extend your day.

The Sony VAIO Fit 14 is a mainstream laptop that's almost an ultrabook with a few glaring drawbacks that keep it in the middle of the pack. If you're interested in the system and its higher resolution screen, give the system a tryout in your local big box store. If you can tolerate the keyboard and if you won't mind carrying the AC adapter with you, the system is a good find. However, for most users, systems like our Editors' Choice for entry-level touch ultrabooks Acer Aspire M5-481PT-6644 are a better choice overall.

Elucidating energy shifts in optical tweezers

May 8, 2013 ? Physicists are providing an all-in-one guide to help calculate the effect the use of optical tweezers has on the energy levels of atoms under study.

A small piece of paper sticks to an electrically charged plastic ruler. The principle of this simple classroom physics experiment is applied at the microscopic scale by so-called optical tweezers to get the likes of polystyrene micro-beads and even living cells to "stick" to a laser beam, or to trap atoms at ultra-low temperatures. Physicist Fam Le Kien and his colleagues from the Institute of Atomic and Subatomic Physics of the Vienna University of Technology, Austria, provide a comprehensive manual with general theoretical tools, definitions, and spectroscopic data sets for calculating the energy levels of atoms, which are modified by light emanating from optical tweezers, in a study about to be published in the European Physical Journal D.

One issue that occurs when trapping atoms with optical tweezers is that the laser beam modifies atoms' energy levels. As a result, it changes the frequency at which the atoms emit or absorb light and microwave radiation. Depending on the experiment, this effect can have important consequences and its magnitude might need to be calculated. Interestingly, the change in the energy levels can be seen as partly due to a fictitious magnetic field, induced by the light field effect on the atoms. This is akin to introducing fictitious forces when describing a body's motion in a rotating reference frame.

The authors show that these fictitious magnetic fields add up to the same effect as real magnetic fields. This will help physicists to intuitively foresee the effects that occur in their experiments when external magnetic fields either cannot be avoided or are intentionally applied. Ultimately, this all-in-one guide could be used in fundamental research as well as for applications such as quantum simulators and quantum computers.

'Downton' vs. 'Thrones': Who's queen of mean?

TV

Drusilla Moorhouse TODAY contributor

19 hours ago

Long before Dame Diana Rigg brought Olenna Redwyne to life this season on HBO's "Game of Thrones," fans of George R.R. Martin's epic fantasy series compared her acerbic character to "Downton Abbey's" Violet Crawley, played with delicious relish by Dame Maggie Smith.

The distinguished actresses have more than their characters' signature wit in common: among other awards, both Brits have received the female equivalent of a knighthood. Smith has picked up two Best Supporting Actress Emmys for the Edwardian period drama, and will likely go head-to-head with Rigg in the category this year.

HBO / Masterpiece Classic

Diana Rigg as Lady Olenna Tyrell on "Game of Thrones," left, and Maggie Smith as the Dowager Countess on "Downton Abbey."

But if the fictional ladyships could meet, who would win the battle of the wits? Let's break this down, period-drama/fantasy style:

Woman of the House: Both elderly matriarchs wield considerable influence behind the scenes in their respective houses (Tyrell and Downton). From the beginning, Violet promoted the match between Mary and Matthew, and despite some (OK, many) hiccups, her wish was eventually granted. Olenna encountered similar roadblocks in her matchmaking efforts (poor Sansa), but she married her granddaughter off to kings. (And probably helped to unmarry her when it counted.) POINT: Olenna

Flower Power: Olenna's nickname is partly derived from House Tyrell's sigil, and she quipped that "when a Tyrell farts it smells like a rose." But Lady Violet is the perennial winner of the Best Bloom in the Village Award (not counting her forfeit to Bill Molesley for his Comtesse Cabarrus rose). What are embroidered pillows compared to the Grantham Cup? POINT: Violet

You've Been Served: Attending to these fussy femmes is a frightening prospect for the hired help. Violet cloaks her complaints in sarcasm ("He looks like a footman in a musical revue!") and gripes ("I was right about my maid. She's leaving -- to get married! How could she be so selfish?"), but the Queen of Thorns is cutting: "Gods, boy, that's enough, we're not in a tavern," she complains to Podrick Payne, before silencing him. "No need to speak!" And don't dare delay her dairy: "The cheese will be served when I want it served, and I want it served now." POINT: Olenna

The Fairer Sex: While men brandish the most power in all eras, these materfamilias happily undermine their authority. "Loras is young and very good at knocking men off horses with a stick," Olenna notes about her grandson. "That does not make him wise." She's even more scathing about his father: "My son's a hunter. It helps him forget he's never been within a mile of a real battle." Violet is more subtle, telling her daughter-in-law that a woman is entitled to her opinions only when "she is married -- and then her husband will tell her what her opinions are." Still, like Olenna, she insists, "I'm a woman?I can be as contrary as I choose." But where Violet is contrary, Olenna is downright cunning, forming powerful alliances (Varys, Tyrion and probably Littlefinger) and a hairnet (?!) to take down her enemies. POINT:Olenna

Trading Barbs: This isn't a fair fight, since Smith has had three seasons to zap zingers compared to Rigg's few episodes. But can Olenna's bawdy barbs ("Once the cow's been milked there's no squirting the cream back up her udder") ever triumph over Violet's high-society zingers? ("Of course it would happen to a foreigner -- no Englishman would dream of dying in someone else's house"; "It always happens when you give these little people power, it goes to their heads like strong drink"; "Don't be defeatist, dear, it's very middle class"). POINT: Violet

The battle may not be as decisive as a joust or cricket match, but in this contest, the Queen of Thorns must be declared the winner. (Your fig and cheese platter is on its way, Lady Olenna!)

Las Vegas Man's Battle with Breast Cancer - 8 News NOW

LAS VEGAS -- Most discussions about breast cancer tend to focus on women, but men are also affected by the disease. Every year, nearly 2,000 men in this country are diagnosed with breast cancer and about 400 die from the disease.

A Las Vegas man received the shocking diagnosis 12 years ago and he wants other men to know it can happen to them.

Lance Wolf, 56, is a husband and a father of two. For the past 12 years, he's taken on another title: breast cancer survivor.

"I knew that a man could get it, but I didn't think I could get it," Wolf said.

He first felt the lump while taking a shower in 2001 and didn't pay much attention to it. It wasn't until his 5-year-old daughter jumped on his chest and made him realize the bump was still there and?he needed to see a doctor.?

"That's the story we told, my daughter saved my life because we played jump on Daddy."

Wolf, who was also 150 pounds heavier at the time went straight to the doctor who told him that his weight was a problem, but not a priority. Wolf was diagnosed with Stage 2 breast cancer.

"I would tell somebody I had breast cancer and the first thing out of their mouth, 'are you kidding?' and I was like why would I kid about that, it's serious stuff."

So serious, that Wolf said he could have died if the cancer had not been caught early.

"You have to do self examination. If you don't do it, by the time you find it, you are dead," he said.

Now a dozen years since his diagnosis, Wolf is cancer free. He's maintaining a much healthier lifestyle which includes taking part in the Race for the Cure in Las Vegas every year.

He is also trying to raise awareness that breast self exams aren't just for women.

"Even if some women see it and they go give their husband a self exam, I think it's really cool."

The next project for Wolf is working with Susan G. Komen to make the self-exam pamphlets and shower cards more men friendly.

Flight behavior of hungry malaria mosquitoes analysed

May 3, 2013 ? Malaria mosquitoes go to work cautiously before landing on human skin and biting. Just before a mosquito lands, it reacts to both odours and heat given off by the human body. Researchers at Wageningen University came to this conclusion after studying images made with infrared-sensitive cameras.

Their research was published in the scientific journal PLOS ONE on 2 May.

Most malaria mosquitoes prefer human blood. They fly in the dark while their host is sleeping. In order to locate a host, they focus on traces of carbon dioxide, released by all animals, and on characteristic human odours. At a distance of 1.5 m from their host, they mainly follow body odours. Just before they land, however, heat radiating from the human body also plays a significant role.

The researchers and technicians at Wageningen University, which is part of Wageningen UR, worked with colleagues from Noldus Information Technology BV using video recordings and automated 3D image analyses to clarify how malaria mosquitoes find their host.

In order to investigate seeking behaviour in mosquitoes, the researchers placed the insects in a special dark wind tunnel measuring 60 by 60 cm, with a length of 1.6 m. The air stream had a constant temperature and humidity, and a speed of 20 cm/second. The flight of each mosquito (Anopheles gambiae) in the tunnel was filmed by means of infrared-sensitive cameras.

When human odours were absent, the mosquitoes continued to fly into the wind through the tunnel.

As soon as the researchers added an odour to the air stream, the mosquitoes followed a complex and long route to the source, and this took about twice as long as without odours. Adding a heat source (34?C, the same as human skin) again doubled the length of the search and was crucial for finding the odour source. Adding heat caused the flight pattern to change drastically whenever mosquitoes came near (about 20 cm) to the source. The exact mechanism of landing will be the subject of a future investigation.

This research at Wageningen demonstrates that the interaction of odour and heat is effective in bringing mosquitoes to a host. This is the first study to make malaria mosquito flight behaviour 'visible' in the dark and it demonstrates that insects are extremely good at orientating themselves towards their host at night. This discovery means that existing odour traps can be enhanced by, for example, adding a source of heat, or by changing the position of the bait in relation to the trap opening. This is one of the ways of controlling malaria, still a serious disease affecting millions of people in large parts of the world. The new information on transmission by the malaria mosquito can be used to combat the disease more effectively.
