For individuals affected, it can constitute a major disability and a decrease in quality of life. Current American societal expectations are that individuals who identify!they are involved in substance abuse will go to treatment, eventually recover, get off public assistance straightaway, and return to work. Most rehabilitation professionals also maintain the same expectations. The reality is that efforts of prevention do not appear to diminish the number of people with substance abuse. Traditional treatment appears to have minimal, if any, influence upon the cessation of substance abuse, and traditional vocational rehabilitation practices appear unsuited for the unique problems and types of symptoms experienced by substance abusers. Creative, yet sound, alternatives that combine effective treatment strategies and non-traditional vocational rehabilitation methods need to be exqlored and tested for effectiveness, and applied.展开更多

The first section provides an introduction to the definitions and theories of chronic pain and the various contributing factors (psychological, interpersonal/environmental and social support, and vocational). The second section presents the role of various health care professions (medical doctors, nurses, physical therapists, occupational therapists, psychologists and rehabilitation counselors) and the evidence of their treatment effectiveness. The third section discusses the concept of an interdisciplinary pain rehabilitation program (IPRP) and its evidence to support its effectiveness. Finally, the clinical implications of rehabilitation counseling and psychology as part of the inter-disciplinary program in treating individuals with chronic pain will be highlighted.展开更多

Health promotion as a preventive method for secondary conditions for persons with disabilities has not been a significant area of interest on the part of the general health care and rehabilitation services community in Western societies. In the U.S., after years of careful evaluation a shift in scientific and advocacy thinking has encouraged researchers, funding agencies, health care providers, rehabilitation professionals and persons with disabilities, as well as the consumers of health care services to prioritize future studies in this specific area and establishing quality health care and the best possible rehabilitation outcomes for millions of individuals with disabilities.展开更多

Method:A total of 251 stroke patients were randomly divided into a standardized rehabilitation group and a control group. The simplified Fugl-Meyer assessment(FMA) scale, the 36-item short-form health survey questionnaire (SF-36) and functional comprehensive assessment (FCA) were administered before as well as after 3, 6 and at 12 months a follow-up study respectively. Statistical analysis was conducted based on the evaluations at 4 testing time points. Result:There was no significant difference in FMA,SF-36 and FCA scores of the two groups before and after 3 months treatments, while FMA,SF-36 and FCA scores of the rehabilitation group were obviously higher than those of the control group either after 6 months treatments or of followup study. Moreover, after 6 months treatments FMA score was apparently higher than the score at the beginning and after 3 months treatments. The FMA, SF36 and FAC scores during the followup visit decreased when compared with scores after 6 months treatments, but increased significantly when compared with the scores at the beginning and after 3 months treatments. Conclusion:Standardized tertiary rehabilitation (STR) at convalescence and sequelae stages can significantly improve motor functions and QOL of stroke patients.展开更多

Method:One hundred and four AIS patients were recruited for this study. The patients were divided into 3 groups:exercise (E group), brace (B group) and combined rehabilitation treatment (brace treatment combined with exercise, CR group). Radiological parameter were used to assess AIS patients before and after treatment. The Chinese version of scoliosis research society-22(SRS-22) patient questionnaires were filled out by patients after treatment. The SRS-22 scores were compared among management groups. Result:The maximal Cobb angles were smaller in E group than in B group or CR group both before and af- ter treatment. The maximal Cobb angles were significantly smaller after treatment than before treatment in B group and CR group. Function/activity was better in E group than in B group or CR group. Self-image/appear- ance and satisfaction with management were better in E group and CR group than in B group. There was no significant difference among treatment groups in pain and mental health. Conclusion:Both brace and combined rehabilitation treatment can reduce the spinal curve of AIS patients. Both exercise and combined rehabilitation treatment have positive influence on self-image/appearance and satis- faction with management. We support preference of combined rehabilitation treatment above brace treatment.展开更多
