Positioning – clinician, assistant and patient.

Correct /ergonomic positioning reduces muscular strain, improves posture reduces stress and allows the clinician to work efficiently and more likely to concentrate on quality work.

If the clinician is right handed they should be seated in the 11o’clock position with the patient’s head in the 12 o’clock position and the assistant in the 2 o’ clock position.
The clinician should aim to work within the 8 to 11 o’clock range and not cross over the 12 o’clock position as this compromises the position of the assistant making it difficult for them to see intraorally. This compromises the assistant’s ability to retract and suction hence increases the risk of injury and discomfort for the patient.

[pic] Fig 1: Positioning for right handed clinician.

Positioning for a left handed clinician is the mirror image of the above position. The clinician should sit between 1 o’clock and 4 o’clock whilst the assistant sits between 8 and 10 o’clock.

Clinician’s position • Feet flat on the floor • Thighs parallel to the floor • Back straight • Shoulders parallel to the floor • Elbows close to the body • Viewing distance of 30-40 cms from focal point. (Loupes can improve posture as they encourage you to sit further back away from patient in order to focus).

Assistant’s position

• Close as possible to the patient • Thighs parallel to patient’s chair • Knees even with the end of the patient’s head rest • Feet on the ring of the assistant’s chair • Eye level 10 – 15 cms above clinician’s

Patient Position

• Ensure the top of the patient’s head is even with the end of the head rest • Midline of the patient’s body is in the midline of the chair

...Good Working Positions To understand the best way to set up a computer workstation, it is helpful to understand the concept of neutral body positioning. This is a comfortable working posture in which your joints are naturally aligned. Working with the body in a neutral position reduces stress and strain on the muscles, tendons, and skeletal system and reduces your risk of developing a musculoskeletal disorder (MSD). The following are important considerations when attempting to maintain neutral body postures while working at the computer workstation: * Hands, wrists, and forearms are straight, in-line and roughly parallel to the floor. * Head is level, or bent slightly forward, forward facing, and balanced. Generally it is in-line with the torso. * Shoulders are relaxed and upper arms hang normally at the side of the body. * Elbows stay in close to the body and are bent between 90 and 120°. * Feet are fully supported by floor or footrest. * Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly. * Thighs and hips are supported by a well-padded seat and generally parallel to the floor. * Knees are about the same height as the hips with the feet slightly forward. Regardless of how good your working posture is, working in the same posture or sitting still for prolonged periods is not healthy. You should change your working position frequently throughout the day in the following ways: *......

Art in the Colonial Project

...Art in the colonial project Art played a significant role in the colonial project because of the nature of what was being depicted. Paintings such as the one done by Barker, show a striking image of the times and the underlying meaning being shown through the characters. Certainly it is an image that could stir strong emotion for parties of both sides of the situation. Looking at the painting done by Thomas Jones Barker it is plainly obvious in the positioning of the people where the power lied within the situation. The image shows the African chief kneeling before the queen accepting a bible. This is a very accurate depiction of the circumstances at the time. A Victorian seeing this image would easily be assured of who was in charge at the time. The suggestion would be that the British Empire were spreading their ways among those who were less, and that the opposition was obliged to accept the better British ways. I would not think it would be an easy image by any stretch of the imagination for a Victorian to imagine the positions in the painting swapped. Because the British were so founded in the idea that their ways were better, and that it was their job to educate the rest of the world on how to be as good as they were, a Victorian would have no reason to imagine such a thing. It is notable that the British people were a proud people and it is not too often proud people put themselves in positions where they can imagine being the little man in the situation. The......

...Text Necks It’s no secret that having good posture is a key attribute to maintaining your health. In today’s world, it is too common to see people slumping over a tiny screened, smart phone for hours on end. According to the author of a newly published study, “Text neck,” is becoming an epidemic in the American society. In the articles “Keep Your Head Up: “Text Neck’ Takes a Toll on the Spine” by Laura Sullivan and “OMG You’re Texting Your Way to Back Pain” written by Jessica Firger, both explain reasons why people experience spinal pain linked to improper posture, how gravity plays a role, and how the hours spent in certain angles can also impact your health. Spinal pain can be linked to a lot of different areas, but the most common way is through improper posture. Posture, is used to describe how your body is positioned when you're sitting, standing and lying down. In an intrusive definition, researchers cited in “Keep Your Head Up; “Text Next’ Takes a Toll on the Spine, good posture is “ears aligned with the shoulders and the ‘angel wings,’ or the shoulder blades, retracted.” (Sullivan 9). While poor posture, quoted from Dr. Hansraj, chief of spine surgery at New York Spine Surgery and Rehabilitation Medicine, actually adds pressure to the spine. The increased weight makes “the cranium become heaver the more you bend your neck.” (Firger 3). Essentially, unnatural positioning of your neck puts you at a higher risk of spinal injury. Millions of people spend hours on......

Training them to do the exercises and proper posture is important because it would help them in doing ADLs in the future. Educate. Teaching is giving information. Educating is imparting knowledge. “To educate” is more concern on the development of the mind. It is very important that the child understood the things we taught them so that they will be more knowledgeable and more aware of the effects of the disease Motivate. To motivate is to give a reason for doing something. As PT students, motivating others is one of the basics of PTs. In the scoliosis screening, it is important to tell the kids the importance of proper positioning so it will not affect their ADLs. Telling them the bad effects of not doing the correct posture would push them to correct themselves and motivating each other as well. Enjoy. Enjoying what you do makes you want to do it even more. On the other side, enjoying what you do makes other people feel happy and enjoy themselves too! So as we do the things we should do, we must enjoy it, be happy because being happy is contagious. It would make others feel glad and the environment would be lighter. So, Enjoy! Nurture. We need to provide them the correct meaning, causes, do’s and don’ts and proper positioning and anything that relates to scoliosis. Providing them these......

Business Communication and Critical Thinking

...through our body language conveys emotional information. A face can light up with enthusiasm and approval. It can express confusion and displeasure. Your eyes express joy, sadness, anger, or confusion. Your posture can create a feeling of a warm welcome or cold rejection. For example the crossing of arms portrays a feeling of rigidness while gathering up your belongings and reaching for your purse signals a desire to end the conversation. Finding the words to say when delivering a message is only part of the communication process. Your body language speaks more than you care to think to your intended target, and it captures the audience’s attention so that they can take in and analyze the point you are trying to get across to them. As mentioned before your facial and body expressions and body movement help convey your message to the receiver. Some are effective and some are ineffective. The effectiveness of demonstrative communication is to captivate your audience and keep their focus on you. Effective demonstrative communication: • Good eye contact shows concern or interest in your audience thus creating a sense of respect for the speaker. • Good posture can reinforce the speaker’s message setting the tone. Positioning your body with upright posture shows confidence. Giving the audience a sense of encouragement to want to hear the message. • Body movement adds meaning to your message. It can make what you are trying to say sound strong and......

Ergonomics in Medical Sonography

...2014). In certain cases, a loss of muscle strength can occur. While this disorder is accumulative, the symptoms considered to be small can evolve to become more critical and also debilitating. Among North American sonographers in 1997, the occurrences of musculoskeletal injury were 84% and increased to 90% in 2008 (Coffin, 2014). According to the Bureau of Labor Statistics (BLS), work-related musculoskeletal disorders are currently responsible for up to one-third of all illnesses reported by employers every year (Preventing Work, 2006). There are numerous influences which precede to musculoskeletal disorder throughout a cycle of time: awkward positions and movement stemming from the persistent and recurrent use of the transducer and positioning of both patients and equipment, perpetual and repeated pressure for unrelenting amounts of time throughout exams, inadequate workplace ergonomics in the design of equipment, chairs, tables, and lighting, increased exam scheduling, and the age, gender, and height of sonographers (Preventing Work, 2006). Previous Studies and Evidence Musculoskeletal disorders in health care workers have been correlated in great portion to patient transfer and lifting activities. Biomechanical studies have shown that these activities place high levels of compressive force on low back structures, exceeding the lifting limits recommended by the U.S. National Institute for Occupational Safety and Health (NIOSH).

...opportunities. There are two main types of serves in volleyball: The underhand serve and the overhand serve. Both types of serves can be broken down into three main components: * Serving posture: The athlete’s body position—correct weight distribution and ideal arm and foot placement—before the actual serve. * The toss: The lifting or throwing of the ball into the air before contact is made. Discussions about the toss usually focus on correct ball positioning, the ideal toss height for each type of serve, and preferred toss techniques. * Contact point: The position of the server’s hand upon the moment of contact. The contact point is significant because it determines the trajectory of the ball. This guide will discuss both basic types of serves in terms of the concepts outlined above because each stage is critical to the successful execution of the serve. The Underhand Serve The underhand serve is a great option for beginning players because it is the easiest of the three types of serves to master. Since every rally begins with a serve, the primary goal of any inexperienced server should be to just put the ball into play. Posture Practicing good underhand serving posture prepares you to be a consistent underhand server and can also prepare you for overhand serving. Here are some serving posture tips to keep in mind: * Feet should be slightly staggered with the foot opposite your hitting arm out in front. * The majority of the server’s body weight......

...because of a lower price point. While the bike would not be a laggard or poorly made, it would nonetheless lack the power and higher-performing components of Ducati bikes further up the product line. This would compel riders to move up into a more powerful bike as owner incomes grow. Innovate a New Niche: Sport Cruiser Cruisers are distinguished from sport bikes by their profiles and the rider position. Sport bikes have forward-leaning postures where the rider’s legs are tucked up underneath the seat. Naked bikes share the same foot positioning but use handlebar risers to bring the posture of the rider to a more upright position. Cruisers have longer wheelbases, higher handlebars and the rider’s feet are positioned on floorboards or pegs that allow a more natural seat position. Of course, Harley-Davidson holds the dominant design ethic for cruisers. Cruisers by other manufacturers emulated the H-D form with some variation. They also sought to distance themselves from the Harley “bad boy” image to attract riders who wanted the posture of a cruiser without the negative image. Ducati could create a sport cruiser category that would be characterized by the upright seating position and foot locations but also with a design that evokes the Ducati style embodied in the rest of the product line. Wheelbases and front fork geometry could be slightly shorter to eliminate the sluggish cornering associated with long wheelbase cruisers. Ducati would launch this model in Europe,......

Tips to Maintain Good Posture

...Tips to Maintain Good Posture We often hear that good posture is essential for good health. We recognize poor posture when we see it formed as a result of bad habits carried out over years and evident in many adults. But only few people have a real grasp of the importance and necessity of good posture. Why is good posture important? Good posture helps us stand, walk, sit, and lie in positions that place the least strain on supporting muscles and ligaments during movement and weight-bearing activities. Correct posture: • Helps us keep bones and joints in correct alignment so that our muscles are used correctly, decreasing the abnormal wearing of joint surfaces that could result in degenerative arthritis and joint pain. • Reduces the stress on the ligaments holding the spinal joints together, minimizing the likelihood of injury. • Allows muscles to work more efficiently, allowing the body to use less energy and, therefore, preventing muscle fatigue. • Helps prevent muscle strain, overuse disorders, and even back and muscular pain. Several factors contribute to poor posture-most commonly, stress, obesity, pregnancy, weak postural muscles, abnormally tight muscles, and high-heeled shoes. In addition, decreased flexibility, a poor work environment, incorrect working posture, and unhealthy sitting and standing habits can also contribute to poor body positioning. How do I sit properly? • Keep your feet on the floor or on a footrest, if they don't reach the floor. • Don't cross......

Demonstrative Communication

...more of all communication, depending on the source you are reading. In many instances what we do not say in the verbal sense can still convey a lot of information. Nonverbal messages can make the communication more effective. For example, pointing to an item can send more accurate information than trying to explain what an item looks like. It can also confuse the issue as in the example of mixed messages sent. Body language refers to the nonverbal cues that we use to communicate. Even when we do not say anything at all, body language can speak volumes about how we feel, what we are thinking, etc. Components of non-verbal communication include, but are not limited to the following: 1. Eye contact 2. Facial expression 3. Posture 4. Gestures 5. Head positions 6. Body movement Eye contact is the primary nonverbal way we indicate engagement, interest, attention, and involvement. Disinterest is highly noticeable when little eye contact is made. The longer the eye contact the greater the intimacy and the more interest is perceived. (Hogan & Stubbs, 2003) Someone who continues to break or avoid eye contact in a conversation may indicate that the person is distracted or uncomfortable. For example, people with anxiety disorders are frequently unable to make eye contact without feeling uncomfortable. One may think that the person who is avoiding eye contact is trying to hide something. Too much eye contact can be seen as confrontational or......

Demonstrative Communication

...Demonstrative Communiation Student Name BCOM/275 August 6, 2012 Instructor Name Abstract Written communication is interaction that can be done through emails, letters, cards, ads, articles, etc. Communication where written or verbal exchanges of words are not present is known as Demonstrative communication. Sending and receiving messages without words is often used to strengthen the message of verbal communication. These messages can be carried through posture, eye contact, body language, gestures, clothing, and overall appearance. Demonstrative communication can sometimes present a different message than that of the verbal message. This type of communication can also tell someone how you feel about them, in regards to being liked or not, whether or not you are interested in them or not. Certain objects can tell a lot about a person and can sometimes say what they are unable to say for themself. There are certain items that are considered to be items of affection such as jewelry, flowers, and teddy bears. These items when presented to someone else can be a means of apologizing, saying congratulations, expressing condolences, showing support, or saying I love you. It is easy to have a nonverbal conversation when the parties are face to face, and the environment is comfortable or suitable for all involved. Demonstrative communication is of importance with any type of conversation. Nonverbal/demonstrative communication may take place against our own intentions. For......

This is because they know what is happening to them and the concern the doctor has. http://examples.yourdictionary.com/examples-of-jargon.html What is posture? “The characteristic way in which someone holds their body when standing or sitting” Posture is a very important part of interpersonal interaction. This is because the way a health professional is standing or sitting can reflect how serious the situation is. By this I mean, if an individual walked into a GPs office and they was slouching on their chair, it would come across as they were laid back and may feel as if they don’t know what they are doing. On the other hand, if an individual walked into a GPs office and they were sitting upright, the individual would have a completely different view of them. If a nursery nurse had to tell a child off for misbehaving, it is more respectable to go down to the child’s level. This is because they would be able to make eye contact and understand they have done wrong.
