If the therapist observes body language that may indicate the patient is uncomfortable with proceeding, the therapist should stop the procedure and ask the patient if it is acceptable to continue. Whatever the form of the consent, it should be given voluntarily and without undue influence from the therapist, and once the patient has given consent they can withdraw their consent at any time during treatment. The information provided can be communicated verbally or by written material, such as an information brochure. The most prudent approach is to use both verbal and written communication (Purtillo, 1984). Once again, Member Organisations are advised to check local laws and health regulations affecting the informed consent process as the legal requirements may vary from country to country. Provision of a brochure is optional, but allows patients time to consider the recommendations, ask questions, and make an informed choice overall. It can be given to the patient to read prior to treatment while they are in the waiting room or in the clinic. If the patient requires further time before making a decision, a brochure can be taken home for consideration. Provision of a brochure ensures that the information is standardised and allows for easy record keeping of the informed consent process by indicating that the brochure was given. It is recommended that the information provided to the patient cover the following points (Appelbaum et al, 1987; Wear, 1998). It is important to note that the points apply to any physical therapy intervention:? Omission of any of the above information may invalidate the consent of the patient. It is the responsibility of the physical therapist to ensure that the patient fully understands all of the information that has been provided. It is also the responsibility of the physical therapist to provide further information requested by the patient and to answer all questions asked by the patient in a manner that the patient considers satisfactory (Wear, 1998). Once again, Member Organisations are advised to check local laws and health regulations affecting the informed consent process as the legal requirements may vary from country to country. The patient has not responded as you had hoped and you would like to now try intervention B. Intervention B is considered to be a new or different treatment to intervention A. Therefore, if the initial process of obtaining informed consent did not include information pertaining specifically to intervention B, the physical therapist must specifically gain informed consent for the use of intervention B prior to its application. This does not necessarily entail the full disclosure of information that was required the first time. Agreement by the patient verbally to the ongoing use of intervention A in most cases would be sufficient. If however, in follow up discussion with the patient, you perceive that there is a lack of understanding of the previously disclosed information, it is recommended that the full process of disclosure of information be revisited. For each treatment, it is recommended that the obtaining of informed consent be recorded each time. The use of stickers (one for the initial informed consent process and one for follow up visits) is suggested to standardise and facilitate ease of recording. The following are necessary considerations for the physical therapist during the selection and application of cervical manipulation (Rivett, 2004; Childs et al, 2005):? The principle of all techniques is that minimal force should be applied to any structure within the cervical spine i. This position allows the physical therapist to monitor facial expressions, eye features, etc. In this situation, a risk may be introduced owing to limited clinical skills and it would therefore be a responsible decision to not use manipulation. The self-evaluative skills of the physical therapist in evaluating their ability to perform the desired technique safely and efficiently are therefore important. Referral to a colleague suitably qualified/trained in the desired manipulative technique may be appropriate.

The position of this mark can then be measured against the rule on the horizontal bar. In recording measurements of degrees of proptosis it is important that an initial measurement between each orbital rim is recorded. The optokinetic drum the optokinetic drum is a device used for the stimulation and assessment of optokinetic nystagmus. Nystagmus can be defined as a repetitive, involuntary, to-and-fro oscillation of the eyes. Nystagmus that occurs in response to a moving object through space is normal and acts to preserve clear vision. The ophthalmologist can observe and classify the degree of fixation, the amplitude and frequency of the oscillation and the plane of the nystagmus by using the drum. This can be helpful in assessing the visual acuity of very young infants and also for the detection of patients feigning blindness. Abnormal responses can indicate brainstem damage, congenital nystagmus, cerebellar disease and demyelination. Nystagmus can also present as a reaction to drugs such as phenytoin, lithium, carbamazepine and barbiturates. A bilateral loss of central vision before the age of 2 years, for example with congenital cataract, will also cause nystagmus. The optokinetic drum is a hand-held instrument consisting of a handle on which is mounted a rotating cylinder. The cylinder is printed with uniform black and white vertical stripes parallel to the axis of rotation. The patient sits in front of the practitioner and is asked to watch the rotating drum. The pachymeter Ultrasonic pachymetry uses echo spike techniques to measure the thickness of the cornea. Corneal measurement is essential in refractive corneal surgery and is becoming increasingly used in the assessment of glaucoma patients. As ultrasonic pachymeters have become more generally used it has become apparent that there is a wider variation in central corneal thickness than previously recognised (Iyamu and Memeh, 2007). Furthermore, measurement of intraocular pressure by Goldman applanation is affected by corneal thickness (Iyamu and Memeh, 2007). The patient sits while local anaesthetic eye-drops such as oxybuprocaine hydrochloride 0. The practitioner can use one corneal location to obtain a set of automatically generated average readings across the cornea. Alternatively, single measurements at positions across the cornea may be obtained. The ophthalmoscope has a flat oval head containing lenses, a mirror and a light beam. Direct ophthalmoscope the direct ophthalmoscope is used to examine the fundus or posterior part of the eye. It will, therefore, allow examination of the retina and retinal blood vessels, the choroid, the optic disc and the macula. Direct ophthalmoscopy is widely used by non-specialist practitioners who do not have access to a slit lamp. It can be used to assess the optic disc, which may be swollen in optic neuropathy or cupped in glaucoma. The condition of the retinal blood vessels could indicate retinal artery or vein occlusions. Haemorrhages may be observed, indicating diabetic retinopathy or retinal vein occlusion. However, direct ophthalmoscopy is insufficient for gaining a good view of the peripheral retina and the patient should be referred for indirect ophthalmoscopy if peripheral pathology or damage is suspected. To use the ophthalmoscope the practitioner sits or stands adjacent to the eye to be examined, preferably examining the right eye with his right eye and hand, and the left eye with his left eye and hand. If this is not seen, then an opacity in the cornea, a dense cataract or a vitreous opacity is indicated and fundal examination will not be possible. Once the red reflex has been seen, the practitioner moves the ophthalmoscope slowly towards the patient and at about 5 cm from the surface of the eye the retina and the optic disc should come into view. These can then be brought into focus by rotating the dial with the index finger until the most suitable lens is found.

And because the situations can be so diverse, a universal solution is also impossible. In fact, it is possible that different mechanisms are involved, depending on the types of injuries and joints. Evidence suggests that, in certain cases, overuse of structures creates microscopic injuries which together may ultimately constitute a significant ailment. It is also known that inflammatory processes are often a culprit and that, in certain cases, space for swelling is limited (by bony structures such as the wrist or the shoulder). Before there is a real illness, the process may be felt, since it can cause pain, discomfort or localized fatigue in the overused region.

The tendency to grasp instruments tightly must be avoided because it decreases fexibility and increas es fatigue of the hand and forearm muscles. In knurled handle general, suturing requires the use of a needle holder, tissue forceps, and suture scissors. Suture-tying forceps are ofen helpful as well, but may not be necessary if the tissue forceps have a tying platform. When suturing under the microscope, very small su a tures and needles are employed, and therefore, a cor respondingly small needle holder should be used. If the needle holder is too large in relation to the needle, the jaws of the needle holder may deform the needle in its grasp, or the needle may be difcult to grasp and pass through tissue. A non-locking needle holder should be used when suturing under the microscope so that the locking and unlocking action does not cause uncontrolled move ment of the needle holder tip, which is undesirable in b the microscopic feld. The jaws of the needle holder should be fat on the inner surface rather than toothed or grooved so that the delicate shafs of the small needles are not inadver tently deformed or twisted when grasped. However, tapered and curved jaws facilitate grasping of suture ends if the needle holder is used for tying (Fig. When grasping a needle with a needle holder, the c needle should be gripped approximately one third of the way forward from the swage end.

Despite the large number of research studies on carpal tunnel syndrome, controversy persists among physicians about its extent and etiology, the contribution of occupational and non-occupational risk factors to its development, the criteria used to diagnose it, the outcomes of various treatment methods, and the appropriate strategies for intervention and prevention. Confusion in the general public is compounded by the poor quality of the information on carpal tunnel syndrome found in the popular media: many patients are misinformed about carpal tunnel syndrome. The purpose of this research is to identify a current, valid, clinically important and applicable foundation of peer-reviewed scientific evidence that can be used to make evidence-based decisions about the diagnosis, causation and treatment of carpal tunnel syndrome. This is because of the heterogeneity of the subject matter of the causation studies, the ethical constraints on experimental research in humans (studies of disease causation must be observational and are more susceptible to bias and confounding than are experimental studies), and the lack of longitudinal studies on causation of carpal tunnel syndrome. Longitudinal studies of causation have the potential to provide the strongest evidence of a temporal, cause-effect relationship. While gaps in the evidence prevent us from drawing firm conclusions in some areas, we are able to reach consensus on a number of essential points. Rigorous diagnosis of carpal tunnel syndrome is the basis of appropriate treatment: the importance of an accurate medical diagnosis cannot be overstated. Despite their limitations, electrodiagnostic studies are the most objective tests available to demonstrate median nerve deficit, and their accuracy is good when properly performed. If surgery is being contemplated, electrodiagnostic confirmation of the clinical diagnosis is desirable. Carpal 93 tunnel syndrome has an indistinct etiology: a variety of contributing factors and conditions can effect the median nerve in the carpal tunnel. Susceptibility to developing carpal tunnel syndrome varies with anatomic structure, body mass index, gender, age, genetic predisposition and psychosocial factors. Systemic conditions and pathologies also contribute to the causation of carpal tunnel syndrome. Carpal tunnel syndrome is a condition that certainly effects workers, but it is not necessarily a condition that is caused by work. The risk depends on the interaction of person and task, and not all cases of carpal tunnel syndrome potentially related to work are in fact directly related to physical activities performed in the workplace. There is some evidence that force, either alone or combined with repetition, is associated with carpal tunnel syndrome, as is vibration: a caveat here is that causal thresholds have not been adequately quantified. Tasks characterized by high frequency but low force (like computer keyboarding) do not appear to be important precipitating factors. There is insufficient evidence of association between other putative occupational risk factors and carpal tunnel syndrome. In the majority of cases, a course of appropriate conservative management is the first step in treatment, except where there is evidence of thenar wasting. If there is evidence of wasting, expedited medical and surgical assessment is required due to the risk of progressive and permanent neurological damage. Concluding his seminal address "The environment and disease: association or causation? That does not confer upon us a freedom to ignore the knowledge we already have, or 47 to postpone the action that it appears to demand at a given time. The intent of this investigation is to establish a foundation of current, clinically valid, important and applicable evidence on the diagnosis, causation and treatment of carpal tunnel syndrome. Down a dark (carpal) tunnel Down a dark (carpal) tunnel Researchers at the University of Pennsylvania who reviewed online resources for patients with carpal tunnel syndrome have concluded that the information available online "is of limited quality and poor informational value. Using established clinical practice as their guideline, the researchers assessed the first 50 sites named by each search engine. Of the remaining 175, the researchers found that 14% provided misleading content, 9% offered "unconventional" information and 31% had content that was based only on opinion or sales pitches.

In practice Screen for undiagnosed diabetes in individuals at high risk25,26 (see Box 1). Tests to detect diabetes Testing high-risk patients or those with a clinical suspicion for diabetes involves three types of biochemical analyses. These states are not considered to be benign and refect a risk of developing diabetes in the future. Microvascular complications are commonly present at the time of diagnosis of type 2 diabetes in both symptomatic and asymptomatic individuals. Screening and diagnosis algorithm Type 2 diabetes: screening and diagnosis Screen individuals at increased risk (refer to Section 3. The Australian Diabetes Society, the Royal College of Pathologists of Australasia, and the Australasian Association of Clinical Biochemists have reviewed the available evidence and confrmed that HbA1c can be used to establish the diagnosis of diabetes. Note that HbA1c may be artifcially normal in people with haemoglobinopathy or haemolysis, and that it may be artifcially high in people with iron defciency. Alternatively C-peptide levels will determine those patients with absence of or minimal insulin production. These occur when blood glucose levels are elevated above normal but1 not high enough to be diagnosed as diabetes. Intervention is warranted only to prevent or delay progression to type 2 diabetes, and to reduce mortality associated with the metabolic condition itself. Clinical trial evidence demonstrates that metabolic disruption leading to diabetes can be stopped and regressed with effective diet and lifestyle modifcation as well as with some drug therapies. The foundation studies demonstrating prevention of type 2 diabetes development by structured lifestyle behaviour change programs were conducted in Finland and the United States of America. Lifestyle modifcation Lifestyle modifcation programs (see Section 6) should be developed using a patient centred approach. These should be individualised with realistic goals based on what the patient can and wants to achieve. Each plan should focus on physical activity, dietary modifcation and weight control. Plans could involve other practice team members and may include referral to allied health professionals such as dietitians, diabetes educators and exercise physiologists or physiotherapists and may include a structured goal-oriented program. Clinical context How well a patient can read and use numbers has a signifcant impact on their ability to self-manage. Patients with diabetes and lower literacy or numeracy skills are at greater risk for poor diabetes outcomes. This ensures a complete understanding of the individual who is living with type 2 diabetes. From a position of mutual understanding, management plans can then be developed with the patient, and tailored to specifcally meet their needs, values and choices. Studies show that patient-centred management plans are more likely to be adhered to and result in better health outcomes. However, systems should be developed within the practice to allow appropriate assessment, review and management of individual patients. Determine the management priorities, focusing on specifc interventions (including those chosen by the patient) that have the most impact on the individual and will form the basis of their continuing care. Consider enrolment in structured programs Both structured diabetes care programs and structured self-management education programs have been developed. See Appendix D for a template of a General Practice Management Plan (structured patient-centred care plan). Clinical context the goal of a structured care program is to increase the quality of life for people with diabetes. Structured care means having all the necessary aspects of the required care in place. The structure of each diabetes care program will vary based on the local circumstances and the needs of the patient. There is good evidence to support patient access to a variety of healthcare providers. There are some team roles that ft into most patients programs but whatever the composition of the team, care needs to be organised and delivered systematically. Multidisciplinary care (see Figure 2) also covers gaps in care that may be apparent to one healthcare provider, but go unnoticed by another. Practice nurses have an important role in team-based care processes, including motivational interviewing, education activities and support for lifestyle modifcation.

Stuster (1993) identified and validated 14 cues useful for identifying alcohol-impaired motorcycle riders. Vehicle impoundment or forfeiture can be an effective deterrent to drinking and driving for all drivers (see Chapter 1, Section 4. Recent research confirmed earlier findings that many motorcyclists do not find traditional impaired driving sanctions such as fines and license suspension to be effective deterrents. However, motorcyclists tended to be highly concerned for the safety and security of their motorcycles (Becker et al. These findings suggest a potentially effective strategy to reduce alcohol-impaired motorcycling: highly publicized enforcement using officers trained in identifying impaired motorcycle riders and other motor vehicle drivers, with offender sanctions including vehicle impoundment or forfeiture. This strategy would treat motorcyclists on an equal footing with other vehicle drivers in impaired-driving enforcement and publicity. Use: the extent to which law enforcement agencies train officers to detect alcohol-impaired motorcycle riders, or include alcohol-impaired motorcycling in any way in their traffic patrol activities, is not known. A major campaign including alcohol impaired motorcyclists may require additional costs for publicity. Motorcyclist groups: Motorcyclist groups likely will object strenuously to any enforcement activities that are perceived to target motorcyclists unfairly. Potentially impairing drugs include over-the-counter and prescription medications as well as illegal drugs. Studies of vehicle drivers, typically in individual hospitals, find drug presence considerably lower than alcohol presence. The extent to which various drugs impair driving performance or contribute to crashes is not well understood, either for four-wheeled vehicles or for motorcycles. Law enforcement should consider drugs as potential impairing agents for motorcycle riders just as for other vehicle operators. Most States will waive the skill test, and sometimes the knowledge test, for motorcyclists who have completed an approved training course. This is perhaps not surprising given the variability of licensing tests and procedures. A companion report (Baer, Baldi, & Cook, 2005) describes effective training and licensing programs and actions to promote training and licensing. Maryland used the additional strategy of comparing their vehicle registration and driver licensing files. This quick and inexpensive strategy caused 1,700 owners to become licensed within four months. However a randomized controlled experiment of this intervention suggested that while the method did increase licensure, a large percentage remained unlicensed (Braver et al. Effective July 22, 2007, the State of Washington added an authorization to impound vehicles operated by drivers without a proper endorsement (including, but not limited to, motorcycles). Maryland and Pennsylvania have one-stop shops that provide a motorcycle endorsement immediately upon successful completion of a State-approved basic riding course. Use: All States require motorcycle riders to obtain a motorcycle license or endorsement to ride on public highways. Effectiveness: the effectiveness of current licensing and testing on crashes and safety has not been evaluated. The costs of changing the licensing tests and procedures depend on the extent of changes and the amount of retraining needed for licensing examiners. Time to implement: New licensing tests and procedures likely would require 6 to 12 months to implement. Baer, Cook and Baldi (2005) report that seven States had some form of graduated licensing in 2001 and five restricted motorcycle riders in some age groups to motorcycles of certain sizes. Evaluations in New Zealand and evidence from Quebec suggest that they may do the same for motorcyclists (Mayhew & Simpson, 2001). This requires cooperation on the part of multiple agencies, including those responsible for collecting and analyzing crash data and those responsible for training and licensing. Forty-seven States have State-operated and legislated education and training programs and the other three have privately operated programs (Baer, Cook, & Baldi, 2005). Many States encourage training either by requiring it for all motorcycle operators under a specified age or by waiving some licensing or testing requirements for motorcycle riders who complete an approved training course (Baer, Cook, and Baldi, 2005). However, it is not at all clear what constitutes good rider education and training, nor whether current training reduces crashes. Beyond just teaching motorcycle control skills, emerging evidence suggests that better programs would also train riders to recognize potentially hazardous riding situations and encourage riders to assess their own risks and limitations, and ride within those constraints.
