Cycling or other non–weight-bearing exercise modalities may be used as a warm-up but should not be the primary type of activity generic 100 mg zudena with amex. A cold environment may aggravate the symptoms of intermittent claudication; therefore generic zudena 100mg visa, a longer warm-up may be necessary (34) cheap zudena line. This can result in motor (functional) cheap zudena 100 mg overnight delivery, sensory, emotional, and cognitive impairments, the extent of which are greatly influenced by the size and location of the affected area and presence or absence of collateral blood flow. The etiology of a stroke is most often ischemic (87%, due to either thrombosis or embolism) or hemorrhagic. Loss of physical stamina, mood disturbance, and adoption of sedentary behaviors are common in stroke survivors. Although the Ex R is often adapted to the functional abilities of thex patients, exercise training improves exercise capacity (10%–20%, as measured by O2peak) and quality of life, and helps manage risk for a secondary event (95). Exercise Testing Compared to those who have not suffered a stroke, oxygen uptake is higher at a fixed submaximal level and reduced at peak effort among stroke survivors. During exercise testing, both chronotropic incompetence and early-onset fatigue are common. Exercise testing should employ a mode of testing that accommodates a patient’s physical impairment. All comorbidities should be considered when prescribing exercise as well as any effects the medications used to treat the comorbidities have on exercise responses or exercise programming. Subsequently, and often in tandem, aerobic, neuromuscular, and muscle-strengthening exercises can be engaged to further improve function, facilitate secondary prevention, and improve fitness. Other Considerations Be attentive to affective issues such as mood, motivation, frustration, and confusion. Correctly managing affective issues can favorably influence how a patient conducts, adheres to, and responds to a prescribed exercise regimen. Strategies aimed at minimizing negative influences due to these issues are helpful and include close supervision, individualized instruction until independence is established, involvement of family members, repetition of instructions, and alternate teaching methods. Early-onset local muscle and general fatigue are common and should be considered when setting work rates and rate of progression. Specificity of training can be employed for both aerobic and resistance training in an attempt to provide an individual with the strength and endurance needed to return to his or her previous occupation. Exercise training leads to an improved ability to perform physical work, an enhanced self-efficacy, and a greater desire and comfort level for returning to work following the illness (79,112). A list of respiratory diseases in which exercise is of potential benefit is shown in Box 9. Bronchiectasis — abnormal chronic enlargement of the airways with impaired mucus clearance Restrictive lung diseases — extrapulmonary respiratory diseases that interfere with normal lung expansion. Examples include the following: Interstitial lung disease/pulmonary fibrosis — scarring and thickening of the parenchyma of the lungs Pneumoconiosis — long-term exposure to dusts, especially asbestos Restrictive chest wall disease, (e. The conclusive evidence for exercise training as an effective therapy for asthma is lacking, and at present, there are no specific evidence-based guidelines for exercise training in these individuals. Some (32,47,101) but not all (94) systematic reviews and meta-analyses have suggested that exercise training can be beneficial for individuals with asthma. The data examined from these reviews are limited by small numbers of randomized controlled trials and heterogeneity of trial methods and subjects. Significant improvements in days without asthma symptoms, aerobic capacity, maximal work rate, exercise endurance, and pulmonary minute ventilation ( E) have been noted. Overall, exercise training is well tolerated and should be encouraged in people with stable asthma (32,39,84). Exercise Testing Assessment of physiologic function should include evaluations of cardiopulmonary capacity, pulmonary function (before and after exercise), and oxyhemoglobin saturation via noninvasive methods. Exercise testing is typically performed on a motor-driven treadmill or an electronically braked cycle ergometer. Immediate administration of nebulized bronchodilators with oxygen is usually successful for relief of bronchoconstriction (40). These tests should be administered by appropriately trained individuals with medical supervision. Evidence of oxyhemoglobin desaturation ≤80% should be used as test termination criteria in addition to standard criteria (9). Exercise Prescription Specific evidence-based exercise training guidelines for people with asthma are not available at this time. However, exercise training is generally well tolerated in individuals successfully managed with pharmacotherapy and when triggers to bronchoconstriction (e. Position statements on exercise in asthma (84) and systematic reviews (32) support this recommendation. Individuals experiencing exacerbations of their asthma should not exercise until symptoms and airway function have improved. Individuals on prolonged treatment with oral corticosteroids may experience peripheral muscle wasting and may benefit from resistance training. Exercise in cold environments or those with airborne allergens or pollutants should be limited to avoid triggering bronchoconstriction in susceptible individuals. Use of a nonchlorinated pool is preferable because this will be less likely to trigger an asthma event. Be aware of the possibility of asthma exacerbation shortly after exercise particularly in a high-allergen environment. This contributes to the loss of muscle strength, power, and endurance and decrements in the performance of everyday functional activities. The beneficial effects of exercise occur mainly through adaptations in the musculoskeletal and cardiovascular systems that in turn reduce stress on the pulmonary system during exercise (114). Patients should be given specific, standardized instructions on how to relate the wording on the scale to their level of breathlessness (13). Because dyspnea scales are subjective, some caution is advised in their interpretation as exercise intolerance may be accompanied by exaggerated dyspnea scores without corresponding physiological confirmation (37). In addition to standard termination criteria, exercise testing may be terminated because of severe arterial oxyhemoglobin desaturation (i. Walking protocols may be more suitable for individuals with severe disease who lack the muscle strength to overcome the increasing resistance of cycle leg ergometers. Arm ergometry may result in increased dyspnea that may limit the intensity and duration of the activity. Pulmonary diseases and their treatments affect both the lungs and skeletal muscles (i. Because muscle weakness and gait and balance abnormalities are among the risk factors for falling (125), lower extremity strengthening and balance training are effective countermeasures. Exercise Training Considerations Higher intensities yield greater physiologic benefits (e. Supervision at the outset of training allows guidance in correct execution of the exercise program, enhanced safety, and optimizing benefit (99). This may allow these patients to tolerate relatively high work rates that approach peak levels (106) and achieve significant training effects. Flexibility exercises may help overcome the effects of postural impairments that limit thoracic mobility and therefore lung function (117). Regardless of the prescribed exercise intensity, the exercise professional should closely monitor initial exercise sessions and adjust intensity and duration according to individual responses and tolerance. In many cases, the presence of symptoms, particularly dyspnea/breathlessness supersedes objective methods of Ex R. Maximizing pulmonary function using bronchodilators before exercise training in those with airflow limitation can reduce dyspnea and improve exercise tolerance (117). Supplemental oxygen is indicated for patients with a P O ≤55 mm Hg or ana 2 SaO ≤88% while breathing room air (2 100). In patients using ambulatory supplemental oxygen, flow rates will likely need to be increased during exercise to maintain SaO >88%. Although inconclusive, there is2 evidence to suggest the administration of supplemental oxygen to those who do not experience exercise-induced hypoxemia may lead to greater gains in exercise endurance particularly during high intensity exercise (87,106,117). Individuals suffering from acute exacerbations of their pulmonary disease should limit exercise until symptoms have subsided. However, these programs should be modified to include disease-specific strategies. Resistance exercise training may be added after the aerobic training is established and well tolerated. Intensities should be below those that would provoke severe dyspnea, oxygen desaturation, or hypertension (11,107). Arm ergometry, heavy resistance training, and pelvic floor exercise should be avoided to reduce the risk of a Valsalva maneuver (5).

For this reason discount zudena online american express, we develop a hypothesis which is the opposite of what we actu- ally believe – this is the null hypothesis purchase zudena 100mg online. This is a phrase that is used when you state (in order to test it) purchase zudena 100mg amex, that there is no relationship between the dif- ferent elements (or variables) under study discount zudena 100 mg mastercard. For example ‘there is no difference in outcomes for parents who attend parenting classes and those who do not. This basic outline of some of the statistics you might come across is to help you understand how statistics are used to tell us about the strength of the results we are looking at. They help us to understand if a particular piece of research helps us to answer a question. Next time you read a paper with sta- tistics in, ask yourself what the statistics say about the results and the strength of evidence presented. The results of qualitative research are not expressed in percentages and num- bers but as words in the form of descriptive themes. Qualitative research is most useful when you are looking for in-depth insight or answers to questions that cannot be answered numerically, when you are asking why? Think of an area of your own practice where you could explore a qualitative question relating to the experience, or understanding, of an issue. Instead, they code the data and build themes according to ideas aris- ing from within it. This is acknowledged in the research process and steps are taken to maintain credibility and trustworthiness in this pro- cess as far as possible. A small sample is required because in-depth understanding (rather than statistical analysis) is sought from information- rich participants who take part. Other approaches to sampling in qualitative research are theoretical – where the sample is determined according to 74 What are the different types of research? For example, the contacts of participants already involved in the research may be invited to enter the study, if they have the relevant experience. Large numbers of participants are rarely used (and are not necessarily appro- priate) in qualitative research. The richness of qualitative data arises from the dialogue between the researcher and the researched and the insights obtained through this pro- cess are only possible because of the interaction between the two. For exam- ple, the interviewer may probe the interviewee about his or her responses to a question and phrase the next question as a direct response to the reply received. Subjectivity is required for the researcher to get an insight into the topic of investigation and objectivity is not strived for. Because the researcher is involved in, and indeed shapes, both the data collection and analysis pro- cess, it is not possible for the researcher to remain detached from the data which is collected. The concept of refexivity refers to the acknowledgement by the qualitative researcher that this process of enquiry is necessarily open to interpretation and that detachment from the focus of the research is neither desirable nor possible. You are likely to encounter many different approaches when you read the literature. Some different approaches to qualitative research 75 are just described in the literature as ‘qualitative studies’ whilst others are named according to the particular qualitative approach that is followed. It is useful to recognize these different approaches and to understand why one approach was selected for a specifc research question. Grounded theory is a way of fnding out about what happens in a social setting and then making wider generalizations about the way things happen. The purpose of grounded theory is to generate a theory from the data and observations that are made. It is a ‘bottom up’ approach in which data is col- lected and analysed and then used to make explanations about the way things happen in social life. Grounded theory is most useful when you want to explore an area which has not been extensively studied and you are looking to develop theory about what is happening in a particular context. They undertook interviews and observations to explore when and why women self harm and concluded that self harm was a mechanism by which women released anger and anxiety. Yet this relief of anxiety was soon replaced by negative consequences of the punishment that followed self harm and hence a negative cycle was instigated. The researchers concluded that practitioners working in detention centres should allow the women to express their anxieties verbally without fear of reprisals. Phenomenology is the study of the ‘lived experience’ or what it is actually like to live with a particular condition or experience. These studies often use in-depth interviews as the means of data collection as they allow the par- ticipant the opportunity to explore and describe their experience within an interview setting. Phenomenology is most useful when you want to fnd out about indi- vidual experiences of an illness, social situation or event. They interviewed eight women about their experiences and from the analysis of these interviews were able to identify common themes. They found that despite the diffculties these women were facing, and contrary to popular belief, most women had a positive experience of childbirth and with indi- vidualized care were able to overcome diffculties caused by their condition. Observation or participant observa- tion and/or in-depth interviews may be undertaken to achieve this. As it seeks to observe phenomena as they occur in real time a true ethnographic study is a time consuming process. Ethnography is most useful when you want to fnd out about a culture or way of life of a group of people in order to understand why they act and behave the way that they do. The researchers undertook observations and interviews with residents in a home for elderly people. By observing and fnding out about the everyday life of the residents with dementia, and their interactions with others, they found that those with dementia were often able to interact with others and had an aware- ness of their situation and surroundings, emphasizing the need to encourage interaction between all residents within a residential setting. Action research is the process by which practitioners or researchers work together to address issues that arise in everyday practice in order to develop a systematic approach to change implementation and the evaluation of change. Action research is a cyclical method of planning, implementing and evaluat- ing change and development in the working environment. Action research is often designed and conducted by practitioners who analyse the data to improve their own practice. Action research is useful when you need to generate improvements in organizations that are not in the form of research fndings, but are generated as solutions from within. Changes in the use of the portfolio as a tool for continuing professional development were introduced and evaluated in the action research project. You may also come across discourse analysis, which is an approach which analyses the use of language in order to understand meaning in complex areas. Using analysis of the language people use in day-to-day communication helps to determine the reality of their beliefs and values rather than what they might say if asked questions or for their opinions. After reading this section, try and summarize your learning on literature reviews, quantitative and qualitative research methodologies. If you are unclear, read the section again or discuss it with a colleague or fellow student. There has been much debate in the research literature about the merits of different approaches to research (i. This is because quantitative and quali- tative approaches look at different things, or different aspects of the same problem; it is not possible or helpful to say that one is better than the other. Both com- mence with a research question and select the appropriate methodology to answer this question. In all research papers, the methods used to undertake the research should be clearly explained and the results clearly presented. This is known as the research process and is the same process as used to describe a systematic review or a primary research paper. The most important thing is that the most appropriate research methodology is used to address what you need to fnd out. The varied research methods are outlined above in order to illustrate that it is not possible to use qualitative methods to address a question where quanti- tative methods are more appropriate or vice versa. It is important that as users of research, we fnd the most appropriate type of research to suit our needs in a particular context. There is general agreement that a ‘hierarchy of evidence’ exists – that is, that research can be ranked in order of importance and that some forms of research evidence are stronger than others in addressing some types of research ques- tions. However, as you can deduce from the previous discussion, there is no one single hierarchy of evidence. The ‘traditional’ hierarchy of evidence for determining effective treatment puts systematic reviews and randomized controlled trials at the top and quali- tative studies at the bottom as shown below (Sackett et al. Anecdotal opinion lowest In order to make sense of this hierarchy, frst of all we need to acknowledge that (systematic) literature reviews are almost always the strongest evi- dence. Therefore most people would agree that a review should always be at the top of any hierarchy.
