Two specific medical interventions (one with a fiber recommendation and one without) with positive reinforcement are likely efficacious treatments for encopresis purchase ranitidine 150 mg online gastritis diet . Biofeedback in combination with medical interventions has shown particular promise in the management of constipation with abnormal defecation cheap 150mg ranitidine gastritis in spanish. Other promising interventions for encopresis include correction of paradoxical contraction purchase 150 mg ranitidine otc gastritis diet , positive reinforcement buy generic ranitidine 300mg line gastritis symptoms dogs, dietary education, goal setting, and skills-building focused on relaxation during defecation. Report of the Working Group on Psychotropic Medications 165 Limitations of Psychosocial Interventions the efficacy of the urine alarm in the management of nocturnal enuresis is well documented in a number of compelling literature reviews (Dooleys, 1977; Houts, Berman, & Abramson, 1994; S. However, patient characteristics predicting best-treatment outcome for the alarm remain unclear. Further, it is unclear whether other components of treatment add to the effectiveness of the urine alarm. Finally, the interaction of enuresis and the frequently occurring comorbid physical conditions, including maturational delays in central nervous system development, of children with enuresis in the context of learning theory remains unknown (Mellon & McGrath, 2000). Limitations of psychosocial interventions for encopresis include the failure of clinical trials to delineate specific symptoms. In addition, the role of adherence on the part of families is unclear, particularly as this may predict treatment outcome or failure. Given that disease management has been associated with familial functioning, the role of the family in predicting treatment outcome is of utmost importance. Finally, there is little research that has provided information with regard to severity and duration of encopresis and how this is influenced by behavioral approaches. Strength of Evidence the basic urine alarm alone is considered to be necessary in the treatment of enuresis; evidence-based research has demonstrated that the urine alarm in combination with dry-bed training is an effective treatment. Further, full spectrum home training has been demonstrated to improve outcome for children with enuresis, but it is classified only as probably efficacious because other studies have not replicated the data from the full spectrum home training behavioral intervention. Other approaches that focus on improving compliance with treatment or Report of the Working Group on Psychotropic Medications 166 incorporate a cognitive focus warrant further investigation, although no information can be provided with regard to their strength of evidence. By contrast to the enuresis literature, in the management of constipation and encopresis, no well-established investigations are available in the extant literature. Specifically, medical interventions that include positive reinforcement and interventions that include biofeedback have been concluded to be probably efficacious (McGrath, Mellon, & Murphy, 2000). The behavioral approaches in the management of enuresis and encopresis have demonstrated the most success relative to other therapies, including pharmacotherapy, in the immediate management of symptoms as well as in ensuring durability once therapy has ceased. Pharmacological Interventions There are no available pharmacotherapies that specifically target encopresis except of those agents that manage constipation. Imipramine was one of the first pharmacotherapies successfully used for the pharmacological management of enuresis. Because the synthesis of this medication was especially costly in oral tablet form (a great deal of the compound would be needed for the purpose of achieving adequate blood levels), the route of administration was soon developed to be administered by means of nasal spray. Thus, durability is clearly in the short-term, with no generalization or hope of durability in the long-term. Although medical interventions designed to reduce constipation are frequently used simultaneously with behavioral approaches and biofeedback to manage encopresis, no specific pharmacological agent has been studied with behavioral approaches for the purpose of managing encopresis. For this reason, behavioral therapy is necessary even if it is employed as an adjunct to pharmacotherapy. Report of the Working Group on Psychotropic Medications 168 Side Effects and Other Limitations of Pharmacological Interventions Limitations in the pharmacotherapy of enuresis. Strength of Evidence the strength of evidence with regard to the use of pharmacotherapy in the short-term management of enuresis is that pharmacotherapy is an effective treatment only for enuresis; there are no known psychotropic medications for encopresis. Combined Interventions As Mellon and McGrath (2000) have observed, the combination of the urine alarm with desmopressin offers significant promise and may push the already high success rates of conditioning approaches to nearly 100%. In support of this conclusion, Woo and Park (2004) examined the efficacy of a urine alarm for the management of enuresis as a second-line therapeutic approach for those children who failed to respond to pharmacotherapy. Findings revealed that after using the urine alarm for those children who failed a trial of pharmacotherapy, over 90% of partial responders became full responders. These findings support the observations of Mellon and McGrath (2000) of the high success rates of behavioral treatments for the management of enuresis. Report of the Working Group on Psychotropic Medications 169 Strength of Evidence No conclusions can be made with regard to strength of evidence of combined psychosocial and psychopharmacological treatments because of the dearth of multimodal studies. Diversity Issues With the exception of the literature that has focused on the difference in the prevalence of enuresis and encopresis among boys and girls (Franklin & Johnson, 2003; Ondersma & Walker, 1998), no studies have focused specifically on pharmacotherapies or on nonpharmacological therapies as they are associated with gender, ethnicity, or race. Treatment response has also not been studied as a function of gender, race, or ethnicity. RiskBenefit Analysis Given the strength of evidence associated with behavioral approaches for the management of enuresis and the limited adverse effects of these therapies documented in the extant literature, behavioral approaches are concluded to be of high benefit and of little risk in the management of enuresis and encopresis in pediatric populations. In both the short and long-term, a number of risks have been associated with imipramine therapy, a tricyclic antidepressant medication that had been used to manage enuresis that could result in problems with cardiac conduction or death. Thus, the benefit of behavior therapy appears to be especially high for both enuresis and encopresis, Report of the Working Group on Psychotropic Medications 170 while the benefit of pharmacotherapy for enuresis is not especially high. No psychopharmacotherapy has been demonstrated to be efficacious in the management of encopresis. Future Directions Behavioral techniques in the management of both enuresis and encopresis have high benefit and low risk and are efficacious in the management of enuresis and probably efficacious in the management of encopresis. The use of pharmacotherapy is efficacious in the management of enuresis, but not without risk. A considerable and recent increase in research has advanced the knowledge base regarding treatment of the most common childhood disorders, providing better guidance to clinicians and improving the ability of clinicians and patients to make better informed treatment decisions. For many of these interventions, the short-term efficacy for decreasing symptoms is fairly well demonstrated. In contrast, evidence supporting the acute impact of treatment on daily life functioning and the long-term impact on both symptoms and other outcomes is less well documented. In particular, safety concerns remain for a number of psychopharmacological interventions.

Moreover, thoracic motor weakness, loss of proprioception and sensory discs have been shown to cause chronic upper back and function, bowel and bladder dysfunction, Brown mid back pain (1921-1924). Thus, radicular pain is felt in deep struc dence for conventional radiofrequency neurotomy tures, in areas remote from the expected dermatome. Consequently, thoracic region is much less common than in the lumbar the recommendation is that therapeutic facet joint or cervical region (1471,1881,1925-1956). Carson et al nerve blocks or conventional radiofrequency neu (1934) in 1971 estimated that the clinical incidence of rotomy may be provided based on the response from thoracic disc prolapse was most frequently at T11/12. The Task Force commonly affected (1935), usually involving individuals (1959) defined thoracic discogenic pain as thoracic in the fourth to sixth decades of life (1931). Quite from an intervertebral disc, and with provocation of often it is difficult to identify differences between at least 2 adjacent intervertebral discs that clearly do somatic and radicular pain which is more complex not reproduce the patients pain, and provided that the in the thoracic spine than lumbar or cervical spine in pain cannot be ascribed to some other source innervat that symptoms are similar in various conditions in the ed by the same segments that innervate the putatively thoracic spine based on the description of neurologi symptomatic disc. The Task Force (1959) cautioned that cal myotomes and dermatomes in multiple reviews and thoracic discography alone is insufficient to conclusively textbooks. Neurological assessment includes tone, co establish a diagnosis of discogenic pain because of the ordination, proprioception, and abdominal and lower propensity for false-positive responses, either because limb reflexes. As it is well known, the plantar reflex is of apprehension on the part of the patient or because particularly important in assessing spinal cord function. In reference to imaging, age-related changes are ex Degeneration of the thoracic disc, along with tremely common in the thoracic spine in asymptomatic end-plate irregularities and changes due to osteo subjects. The great majority of patients with radiologic phyte formation, are common findings (1960-1964). A high prevalence of Four systematic reviews evaluating the role of provo anatomic irregularities has been found in asymptomatic cation discography in the diagnosis of spinal pain patients (458,1957). Even though plain radiograph is the have presented limited evidence supporting the role most common imaging technique, it does not satisfy the of discography in identifying the subset of patients objective of identification of the cause of the pain and with thoracic discogenic pain (37,697,700,1920).

Our literature search raises concerns that it is too sensitive, thus giving rise to yielded no additional studies. In most instances it can reliably distinguish infection, fracture, and tumor (458).

Lumbar extension the neural arch resists approximately 60-70% of the applied bending moment when extended to its elastic limit, resulting in facet joint loading. Beyond this, damage can be detected after an average of 5 (range 3-8) into the elastic limit (Adams et al. Concentrations of compressive stress appear 16 in the posterior anulus after just 2 of lumbar extension (Adams et al. Functional movements which are likely to increase loads towards the end of available lumbar extension include standing, walking, running, ceiling painting, hanging clothes on a line, shaving, washing hair, high jumping, fast bowling at cricket and playing overhead sports such as tennis and volleyball (Bible et al. Functional tasks which approximate end-of-range flexion include lifting from a squat, putting shoes on, gardening, sitting-to-stand and sports such as gymnastics, lawn bowls, cycling and rowing (Bible et al. Side-flexion of the lumbar spine has not been studied to the same depth as sagittal plane movement. Legaspi and Edmond (2007), in a systematic review of 24 articles on lumbar coupled motion, concluded that there was little agreement across the articles as to the specific characteristics of coupled motion. The risk of assuming a coupled motion, or normal facet morphology, is increased when attempting high velocity, low amplitude manipulative techniques towards end-of-range lumbar positions. Active movement examination of the lumbar spine Physical examination incorporates an active movement assessment which can be planar (Pearcy and Hindle, 1989, Madson et al. A planar movement 18 examination of the lumbar spine involves asking the patient to move their low back in the three cardinal planes sagittal, coronal and transverse (Figure 2. Functional tests are specific to the patients lifestyle and may include everyday tasks such as sitting-to stand, rolling in bed or putting on lace-up shoes, as well as patient-specific tasks such kicking a ball, diving or hitting a golf ball (Figure 2. However, examination of the patient by individually stressing the spine in all three planes of movement simultaneously, such as the Quadrant test, is likely to be difficult for even the asymptomatic spine, and makes interpretation of the pathoanatomy for symptomatic 19 patients increasingly difficult. Combining rotation as a third plane of movement is more difficult to perform for a patient, difficult to control as an examiner, and incorporates a more passive component to the active test (Maitland, 1997). This is partly due to the lack of good quality studies meeting inclusion criteria, varied examination methods and generally low reported specificity. In addition, patient specific function will vary between genders, age groups and lifestyles. In a more recent study of 323 asymptomatic volunteers aged 25-75 years, Dreischarf et al. Many 3-D lumbar spine tracking studies were published in the late 1990s when accurate and reliable motion tracking technology became available. There was no follow-up study demonstrating exactly what these differences are, or why, and whether or not invasive pain intervention or neurosurgery normalises the lumbar spine movement patterns. Brown also suggests that the likely causative structure at fault may be speculated on from its anatomical location in the motion segment, and that every condition will have a different pattern in variance to that found in the norm. With the advance of technology, non-invasive methods of kinematic measurement of the human lumbar 23 spine using 3-D tracking systems with skin mounted sensors have been shown to be valid methods of measuring lumbar kinematics (Barrett, 1995, Mieritz et al. However, measurement of spine movement using skin-mounted sensors in rotation includes large movements of the skin and thorax, and overestimate movements measured by radiographs (Adams et al. Lumbar speed measures are a complex neuromuscular synergistic co-ordination, requiring motivation, skill, strength and flexibility, and metabolic support. Speed is sensitive to any of these factors, and not specific to the cause of impairment (McGregor et al. Statistics relevant for movement analysis Descriptive statistics are used in studies reporting 3-D motion tracking of the lumbar spine for validation purposes (Mannion and Troke, 1999, Sutherland et al. Additionally, this review suggested that Pearson correlation coefficient is not appropriate for reliability studies. A clinically significant improvement may be higher for certain interventions depending on multiple factors including risk, cost and psychosocial factors (Carragee and Cheng, 2010). Cluster analysis can be used with multivariate data to discover natural similarities amongst patient populations. The hierarchical cluster analysis, using Euclidean distances, are sensitive to differences in elevation as well as profile shape (Blashfield, 1980). Using cluster analysis, data related to gender, height and weight have been identified as factors related to spinal posture (Roussouly et al. The use of cluster analysis has also shown that patients with spinal pain can be grouped into these three clusters (Fanciullo et al. Clusters can be used to guide future research and investigate the benefits of specific therapies (Fanciullo et al. Learning clinical reasoning In the clinical setting, even with new knowledge, a clinician is encouraged to analyse and consider the patients assessment findings. Two common models for clinical reasoning include hypothetico-deductive and pattern recognition. Hypothetico deductive reasoning starts by hypothesising the cause of the presenting condition, followed by a process of elimination through assessment and reassessment. Although several possible reasons could easily be proposed as the source of a patients condition, it is reported that between three and five diagnostic hypotheses are 26 common, and this may be linked to various factors, including short-term memory (Elstein, 2009). When learners do the same, their reasoning can be assessed and improved with feedback (Pinnock and Welch, 2014). Competence in clinical reasoning is acquired by practising under supervision with effective feedback, and trainees can learn clinical reasoning effectively if teachers provide guidance in making diagnostic decisions (Pinnock and Welch, 2014). Overview this chapter describes the research method used in each of the studies in this thesis. These studies used quantitative and qualitative methods to report lumbar spine function in asymptomatic and symptomatic populations. Research design Two pilot studies used a repeated measures design in validation studies to test the accuracy of a measuring device. Five studies formed chapters in this thesis, with three subsidiary published papers presented in related appendices.
