Objective: The purpose of this study was to investigate the effects of a short thumb opponens splint on the upperextremity and hand functions in a child with an obstetric brachial plexus injury. Methods: This single-subject experimental design study of an 11 year-old male patient diagnosed with an obstetricbrachial plexus injury was conducted using the ABA’ design. A total of 20 sessions were held, once a week for20 weeks. During the baseline period, five sessions were assessed without intervention. During the interventionperiod, ten sessions were assessed after intervention with a 6 h short thumb opponens splint. In the follow-upperiod, five sessions were assessed without intervention. To measure the upper extremity and hand functions, aBox and Block Test(BBT), nine-hole peg test, mallet scale, and an active movement scale were assessed before,during, and after intervention. Results: After intervention with a short thumb opponens splint, the participant showed significant improvement inhand(BBT, nine-hole peg test) and upper extremity(mallet scale, active movement scale) functions anddemonstrated improvement. Conclusion: The results of this study suggest that use of a short thumb opponens splint has a positive effect on theupper extremity and hand functions. These results can be used to form basis of a clinical intervention in patientswith an obstetric brachial plexus injury.

Objective: The purpose of this study was to develop a Korean version of a Life balance Inventory (K-LBI) formeasuring occupational balance. Methods: A translation and back translation of the LBI were first conducted, and the back translated and originalversions were compared to each other by the original author. Reports from 13 occupational therapists werecollected to investigate the content validity of 53 items in the K-LBI. An Item-level Content Validity Index(I-CVI) and Cronbach's alpha were calculated to verify the validity and reliability of the K-LBI. The correlationcoefficient and intra-class correlation coefficient were used to verify the convergent validity and test-retestreliability. Results: The average value of the I-CVI for 53 items was 0.79. A questionnaire survey was executed for 165community residents including adults and older adults. The coefficients were .356 (p=.01) and .490 (p=.01)based on a correlation analysis between the total average of the K-LBI and the Korean version of theWHOQOL-BREF, and the mental component score of SF12v2. Cronbach’s alpha was .875 and .831 based on theresults of older adults and adults. Conclusion: The K-LBI was verified as an occupational balance measurement with validity and reliability. It ispossible to use the K-LBI for people suffering from a low quality of life resulting from an occupational unbalanceto adjust their daily routine for a more balanced life.

Objective: The purpose of this systematic review is to provide basic data on the effects of physical activity on theexecutive function for older adults with a Mild Cognitive Impairment(MCI). Methods: A systematic search of PubMed, CINHAL, Medline, PsychINFO, Embase, and Cochrane was performed inaccordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis(PRISMA) guidelines. The risk of bias was assessed using the Cochrane collaboration tool. Using the terms “MCI” OR “mild cognitiveimpairment” AND “physical activit*” OR “physical performance” OR “physical exercise*”, AND “executivefunction*” as the search items, 11 Randomized Controlled Trial(RCT) studies, published between 2005 and 2017,were critically appraised and synthesized. Results: Interventions were mostly provided in groups as a multicomponent program. Fitness trainers, followed byphysical therapists and occupational therapists, provided the interventions. Trail Making Test(TMT)-A(21.40%)and TMT-B(17.90%) were the most common outcome measures. For a physical activity intervention, theaerobic component was the most popular(seen in eight studies, 72.70%), followed by non-aerobic(seven studies,63.60%). The aerobic and non-aerobic components had positive effects on the executive function compared tothe leisure component. Conclusion: The effects of physical activity on the executive function for older adults with an MCI were examinedin this review. To thoroughly understand the effects, the physical activity along with a cognitive approach in thefield of occupational therapy needs to be researched.
