A systematic literature review and meta-analysis of the clinical effects of aroma inhalation therapy on sleep problems.

BACKGROUND: This systematic review investigated the clinical effects of inhalation aromatherapy for the treatment of sleep problems such as insomnia. METHODS: Studies on sleep problems and inhalation aromatherapy, published in Korean and international journals, were included in the meta-analysis. Five domestic and international databases, respectively each, were used for the literature search. Keywords included sleep disorder, sleep problems, insomnia, and aroma inhalation, and the related literature was further searched. After the screening, selected articles were assessed for their quality and conducted the risk of bias using RevMan 5.0, a systematic literature review was then conducted. A meta-analysis comparing the averages was conducted on studies that reported numerical values. Additionally, meta-analysis of variance and meta-regression analyses were performed. RESULTS: Meta-analysis of the 34 studies using the random-effects model revealed that the use of aromatherapy was highly effective in improving sleep problems such as insomnia, including quantitative and qualitative sleep effects (95% confidence interval [CI], effect sizes = 0.6491). Subgroup analysis revealed that the secondary outcomes including stress, depression, anxiety, and fatigue were significantly effective. The single aroma inhalation method was more effective than the mixed aroma inhalation method. Among the single inhalation methods, the lavender inhalation effect was the greatest. CONCLUSION: Inhalation aromatherapy is effective in improving sleep problems such as insomnia. Therefore, it is essential to develop specific guidelines for the efficient inhalation of aromatherapy. ETHICS AND DISSEMINATION: Ethical approval is not required because individual patient data are not included. The findings of this systematic review were disseminated through peer-reviewed publications or conference presentations. PROSPERO REGISTRATION NUMBER: CRD42020142120.

A protocol for systematic review and meta-analysis on psychosocial factors related to rehabilitation motivation of stroke patients.

BACKGROUND: Rehabilitation motivation is more important than any other factor in terms of treatment effects among stroke patients. The goal of this study is to explore the variables related to rehabilitation motivation that affect treatment effects and analyze their effect sizes, in order to manage the psychosocial interventions required by stroke patients. METHODS: Thirteen electronic databases will be searched from November to December 2020. The search terms will be composed of the disease term part (eg, "stroke") and the intervention term part (eg, "rehabilitation motivation or rehabilitation factors related to motivation or self-efficacy or family support or rehabilitation adherence or achievement or psychosocial factors, including self-motivation, social support, psychological distress, rehabilitation adherence"). Selected studies the for systematic review and meta-analysis will include randomized, quasi-randomized, and nonrandomized controlled trials, and research programs on rehabilitation motivation; qualitative research and case studies will be excluded. The participants will be stroke patients. Two authors will independently assess each study for eligibility and risk of bias, and to extract data. RESULTS: This study will comprehensively explore the psychosocial and physical behavioral variables related to the rehabilitation motivation of stroke patients and provide their priorities and effect sizes. In addition, we will report the magnitude of the correlation effect on the rehabilitation motivation of stroke patients according to each demographic variable. CONCLUSIONS: The conclusions of our study will provide effective evidence of psychosocial variables that influence the treatment outcomes of stroke patients.

Non-immersive Virtual Reality Rehabilitation Applied to a Task-oriented Approach for Stroke Patients: A Randomized Controlled Trial.

BACKGROUND: Virtual reality (VR) training allows the creation of the most applicable practice environment incorporated into computer-generated multisensory imagery. OBJECTIVES: The purpose of this study was to investigate the effects of a virtual training program based on a RAPAEL smart glove on the upper extremity function and quality of life of community-dwelling individuals with chronic hemiparetic stroke. METHODS: Thirty-six outpatients diagnosed as having a first stroke were selected to receive a therapeutic rehabilitation program at local rehabilitation units. Participants were allocated randomly into two groups: the non-immersive VR training (intervention) group and the recreational activity (control) group. The intervention group received non-immersive VR training using a RAPAEL smart glove for 30 minutes per session, 3 days a week for 8 weeks. The control group performed recreational activities for the same period and also participated in a conventional rehabilitation program for 30 minutes per session, 3 days a week for 8 weeks as an additional therapy. To analyze the effects of the non-immersive VR intervention on upper extremity function, four clinical measures, namely the box and block test (BBT), the Wolf motor function test (WMFT), the Jebsen-Taylor hand function test (JTT), and a grip strength test, were used in this study. For the secondary clinical outcome, the trail-making test (TMT) was used to determine any improvement in cognitive function. RESULTS: At week 8, upon completion of the non-immersive VR-training the intervention group demonstrated significantly greater WMFT scores (73.0±12.9 to 81.6±7.5), BBT scores (27.3±8.9 to 34.2±7.1), and grip strength (19.2±8.2 to 23.8±8.5) compared with WMFT scores (70.4±12.1 to 73.2±13.1), BBT scores (27.1±10.5 to 28.8±12.9), and grip strength (18.4±4.2 to 18.3±4.9) in the control group. CONCLUSIONS: This study suggests that virtual upper extremity training using the RAPAEL smart glove has reasonable and beneficial effects on upper extremity and cognitive function for chronic hemiparetic stroke survivors.
