Reliability and validity of alternate step test times in subjects with chronic stroke

OBJECTIVE: (i) To investigate the intra-rater, inter-rater and test-retest reliability and minimal detectable change of the Alternate Step Test (AST) when assessing people with chronic stroke. (ii) To quantify the correlation between AST times and stroke-specific impairments. DESIGN: Cross-sectional study. SETTING: University-based rehabilitation centre. PARTICIPANTS: A convenience sample of 86 participants: 45 with chronic stroke, and 41 healthy elderly subjects. METHODS: The AST was administered along with the Fugl-Meyer Lower Extremity Assessment (FMA-LE), the Five Times Sit-To-Stand Test (FTSTS), limits of stability (LOS) measurements, Berg Balance Scale (BBS) scores, Chinese-translated Activities-specific Balance Confidence Scale (ABC-C) ratings, and the Timed “Up and Go” test (TUG). RESULTS: Excellent intra-rater, inter-rater and test-retest reliability were found, with a minimal detectable change of 3.26 s. AST times were significantly associated with FMA-LE assessment, FTSTS times, LOS in the forward and backward directions and to the affected side, BBS ratings and TUG times. CONCLUSION: AST time is a reliable assessment tool that correlates with different stroke-specific impairments in people with chronic stroke.published_or_final_versio

Early intervention for psychosis in Hong Kong - the EASY programme

Aim: This article aims to describe the Hong Kong experience in developing and implementing an early psychosis programme. Methods: In 2001, the Early Assessment Service for Young People with Psychosis programme was launched in Hong Kong, providing both educational and service components. Public education includes promotion of timely help-seeking, accessible channels to service and knowledge of psychosis. The 2-year phase-specific intervention includes intensive medical follow-up and individualized psychosocial intervention. The programme has adopted the case-management approach, in which case managers provide protocol-based psychosocial intervention. The programme collaborates with non-governmental organizations and community networks in the provision of rehabilitation service. Results: An average of over 600 young patients enter the programme for intensive treatment each year. Based on preliminary data from a 3-year outcome study, patients in the programme have remarkable reductions in hospital stay accompanied by improvements in vocational functioning. Conclusions: The results suggested that the programme improved patients' outcome. Additional costs such as extra medical staff and medications may be offset by the shortened hospital stay. Further directions in early intervention are also discussed. © 2010 Blackwell Publishing Asia Pty Ltd.postprin

Yoga and aerobic exercise in early psychosis: neurocognitive effects and brain changes of a novel clinical strategy

Session: Cognitive neuroscience: FC-09 Free Communications: no. FC-09-006OBJECTIVE: The current study aims to explore the effects of aerobic exercise and mind-body exercise (yoga) on cognitive functioning and clinical symptoms for female patients in the early phase of psychosis. We further propose to investigate potential mechanism underlying the clinical consequences. METHOD: 120 female early psychosis patients were recruited from three hospital/clinic sites and randomized into integrated yoga, aerobic exercise, and control groups. 82 patients completed the 12-week study (29 in yoga group, 25 in exercise group, and 28 in control group). Both interventions were held three times weekly, with each session lasted for an hour. All ...postprin

The impacts of yoga and aerobic exercise on neuro-cognition and brain structure in early psychosis: a preliminary analysis of the randomized controlled clinical trial

This journal suppl. entitled: Abstracts of the 3rd Biennial Schizophrenia International Research ConferenceCognitive impairment was detectable in early psychosis together with a decreased hippocampal volume (Wright et al., 2000). These cognitive deficits of attention and memory often result in severe and longstanding functional impairment. Reducing cognitive impairment with pharmacological intervention has not been universally successful (Addington, 2007). The current study aims to explore the effects of aerobic exercise and mind-body exercise (yoga) on cognitive functioning and brain structure for female patients in the early phase of psychosis. We further propose to investigate potential differential effects of these two forms of exercise. 61 female early psychosis patients were recruited from two hospital/clinic sites and randomized into aerobic ...postprin

Recovery in Psychosis from a Service User Perspective: A Systematic Review and Thematic Synthesis of Current Qualitative Evidence

There is a growing number of qualitative accounts regarding recovery from psychosis from a service user perspective. The aim of this study was to conduct a systematic review of these qualitative accounts. A thematic synthesis was utilised to synthesise and analyse seventeen studies included in the review. Studies were included if they used a qualitative methodology to explore service users’ experiences of recovery from psychosis as a primary research question. All included studies were subjected to a quality assessment. The analysis outlined three subordinate themes: the recovery journey, facilitators of recovery (e.g. faith and spirituality, personal agency and hope), and barriers to recovery (e.g. stigma and discrimination, negative effects of mental health services and medication). Recovery is an idiosyncratic process but includes key components which are important to people who experience psychosis. These should be explored within clinical practice

Transition to psychosis: 6-month follow-up of a Chinese high-risk group in Hong Kong

Objectives: The identification of individuals at high risk of becoming psychotic within the near future creates opportunities for early intervention before the onset of psychosis. This study sets out to identify a group of symptomatic young people in a Chinese population with the high likelihood of transition to psychosis within a follow-up period of 6 months, and to determine the rate of transition to psychosis in this group. Method: Symptomatic individuals with a family history of psychotic disorder, sub-threshold psychotic symptoms or brief transient psychotic symptoms were identified using the operationalized criteria of an 'At Risk Mental State'. The individuals were prospectively assessed monthly on a measure of psychopathology for 6 months. Results: Eighteen out of 62 individuals (29%) made the transition to frank psychosis within a 6 month follow-up period, with the majority occurring within 3 months. In addition, significant differences were found in the intake Positive and Negative Syndrome Scale, Comprehensive Assessment of 'At Risk Mental State' and Global Assessment of Functioning scores between the group that ultimately became psychotic and the group that did not. Conclusion: The period of the highest risk of transition to psychosis was within the 3 months after the study began. Thus, distressed youths in our outpatient clinic, who meet the high-risk criteria should be monitored most closely in the initial 3 months, particularly those individuals with high levels of psychopathology and functional decline. © 2006 The Authors; Journal compilation © 2006 The Royal Australian and New Zealand College of Psychiatrists.link_to_subscribed_fulltex
