(Taylor & Francis, 2023-08-07) Sivakanthan, Sivashankar; Cooper, Rosemarie; Lopes, Celia; Kulich, Hailee; Deepak, Nikitha; Lee, Chang Dae; Wang, Hongwu; Candiotti, Jorge L; Dicianno, Brad E; Koontz, Alicia; Cooper, Rory A
Purpose: Existing automated vehicle transportation guidelines and regulations have minimal guidance to address the specific needs of people with disabilities. Accessibility should be at the forefront to increase autonomy and independence for people with disabilities. The purpose of this research is to better understand potential facilitators and barriers to using accessible autonomous transportation. Methods: Focus groups were conducted with key stakeholders derived from people with disabilities (n = 5), travel companions/caregivers (n = 5), and transportation experts or designers (n = 11). Results: The themes include describing stakeholder perceptions across all three groups by identified themes: autonomous vehicle assistive technology, autonomy vs automation, cost, infrastructure, safety & liability, design challenges, and potential impact. Conclusion: Specific gaps and needs were identified regarding barriers and facilitators for transportation accessibility and evidence-based guidance. These specific gaps can help to formulate design criteria for the communication between, the interior and exterior of accessible autonomous vehicles.

(2024-04-24) Wonnell, Cassie; Gulyas, Belle; DeGeorge, August; Knoy, Morgan; Warrick, Emilee; Fowler, Avery; Chase, Anthony; Lee, Chang Dae; Department of Occupational Therapy, School of Health and Human Sciences
This rapid systematic review evaluates the current literature on occupational therapy interventions aimed at improving ADL independence in post-stroke individuals. 28 studies were evaluated and 6 categories (task-oriented training, virtual reality and video games, technology, constraint-induced movement therapy, electrical stimulation, and other) of interventions were identified. The 28 articles used in this rapid systematic review were retrieved from PubMed and CINAHL using Covidence. Literature included are publications from the past 10 years, studies with participants 60+ years of age that have experienced a stroke, and studies with interventions focused on ADL independence. Level IV and V studies were excluded. TOT, CIMT/mCIMT, technology, E-stim, VR and virtual reality, sensory interventions, ankle-foot orthoses, and strategy training are evidence-based stroke interventions that have been showing improvement in ADL participation when compared to the standard of care. Findings reveal overall moderately strong evidence for the impact of the identified occupational therapy interventions on ADL performance for adults 60+ post-stroke. The current review supports six categories of interventions that improve ADL independence, which informs occupational therapy practice for older adult stroke patients.
Autobiographical Memory Function as a Related Factor to Resilience of Older Adults
(2023-05-25) Park, Sangmi; Lee, Chang Dae; Kim, Jung-Ran; Kim, Tae Hui; Park, Ji-Hyuk
Purpose: This study aimed to measure the autobiographical memory function (AMF) of community-dwelling older adults to analyze its association with reminiscence function and with resilience. Methods: A survey was conducted on cognitively and psychologically healthy older adults aged 60 years and older living in the community. The Korean Version of Thinking About Life Experiences, Connor-Davidson Resilience Scale, and Reminiscence Functions Scale for the Elderly were used to measure AMF, resilience, and reminiscence function, respectively. Pearson correlation analysis and hierarchical regression analysis were conducted to examine the associations between variables. Results: The mean age of the participants was 73.14 years (SD = 7.59) (n = 121). The mean score of AMF was 1.99 (SD = 0.72). AMF tended to decrease with age (p = .32). AMFs were positively associated with reminiscence functions (p < .001). After controlling for sociodemographic and health characteristics, AMF was positively associated with resilience (β = 0.229, p < .05). AMF explained 4.2% of the variance in resilience. Conclusion: The study confirmed that AMF is a related factor to the resilience of older adults. Further studies are recommended to measure AMF with various samples, including older adults with depression and cognitive decline, and to analyze it’s association with health-related variables in order to support the advantage of AMF in older adults’ health.

(MDPI, 2024) Cooper, Rory A.; Smolinski, George; Candiotti, Jorge L.; Satpute, Shantanu; Grindle, Garrett G.; Sparling, Tawnee L.; Nordstrom, Michelle J.; Yuan, Xiaoning; Symsack, Allison; Lee, Chang Dae; Vitiello, Nicola; Knezevic, Steven; Sugar, Thomas G.; Schneider, Urs; Kopp, Verena; Holl, Mirjam; Gaunaurd, Ignacio; Gailey, Robert; Bonato, Paolo; Poropatich, Ron; Adet, David J.; Clemente, Francesco; Abbas, James; Pasquina, Paul F.; Occupational Therapy, School of Health and Human Sciences
Despite advances in wearable robots across various fields, there is no consensus definition or design framework for the application of this technology in rehabilitation or musculoskeletal (MSK) injury prevention. This paper aims to define wearable robots and explore their applications and challenges for military rehabilitation and force protection for MSK injury prevention. We conducted a modified Delphi method, including a steering group and 14 panelists with 10+ years of expertise in wearable robots. Panelists presented current wearable robots currently in use or in development for rehabilitation or assistance use in the military workforce and healthcare. The steering group and panelists met to obtain a consensus on the wearable robot definition applicable for rehabilitation or primary injury prevention. Panelists unanimously agreed that wearable robots can be grouped into three main applications, as follows: (1) primary and secondary MSK injury prevention, (2) enhancement of military activities and tasks, and (3) rehabilitation and reintegration. Each application was presented within the context of its target population and state-of-the-art technology currently in use or under development. Capturing expert opinions, this study defines wearable robots for military rehabilitation and MSK injury prevention, identifies health outcomes and assessment tools, and outlines design requirements for future advancements.
Depressive Symptoms Mediate Associations between Subjective Memory Complaints, Cognitive Ability, and Instrumental Activities of Daily Living
(Taylor & Francis, 2023-04-10) Lee, Chang Dae; Foster, Erin R.; Goverover, Yael
Objectives: Cognitive ability (CA) and instrumental activities of daily living (IADL) performance are essential for productive aging. Therefore, it is important to understand if other common issues such as subjective memory complaints (SMCs) and depressive symptoms are related to CA and IADLs, and explore the nature of those relationships. This study aims to explore 1) the associations between SMCs, depressive symptoms, CA, and IADL performance and 2) the role of depressive symptoms in these associations. Method: The study sample included 1,621 community-dwelling oldest-old from the Health and Retirement Study. Results: SMCs were significantly and positively associated with cognitive decline and limitations in IADL performance. Additionally, depressive symptoms mediated the associations between SMCs and cognitive decline and between SMCs and limitations in IADL performance. Conclusion: Depressive symptoms associated with SMCs negatively affect CA and IADL performance. Therefore, healthcare providers should consider and assess SMCs and depressive symptoms in the oldest-old.

(Wolters Kluwer, 2024) Lee, Chang Dae; Peterson, Sara; Joseph, James; McKernan, Gina; Cooper, Rosemarie; Koontz, Alicia M.; Dicianno, Brad E.; Cooper, Rory A.; Occupational Therapy, School of Health and Human Sciences
Objective: This study aims to enhance the accessibility and quality of mobility-assistive technology by investigating and bridging knowledge gaps between mobility-assistive technology providers and consumers with ambulatory limitations. Design: A survey was conducted among mobility-assistive technology providers in the United States, consisting of sections on awareness, knowledge importance and desire, and knowledge sources. The responses were compared to data collected from consumers in a previous study. Results: A total of 144 mobility-assistive technology providers participated, with 60% having received academic or professional training in relevant fields. Analysis revealed significant knowledge gaps between providers and consumers, particularly in assistive technology assessment tools and knowledge sources. Moderate gaps were also observed in areas such as clinical practice guidelines, desired mobility-assistive technology information, and knowledge sources. However, the gaps in other areas were relatively small. Conclusions: This study highlights the knowledge gaps between mobility-assistive technology providers and consumers, hindering the optimal utilization and fulfillment of user needs. Providers possess valuable information that consumers may lack, positioning them as primary knowledge sources. Addressing these gaps through targeted interventions, improved communication channels, and enhanced education can enhance the utilization of mobility-assistive technology and improve outcomes for individuals with ambulatory limitations.
Effects of Client-Centered Home Modification and Caregiver Education on Activity Performance and Satisfaction of Persons With Mild Dementia: A Case Study
(2016-03-16) Lee, Chang Dae; Jung, Min Ye; Kim, Jae Nam
Objective: The purpose of this study was to investigate the effects of client-centered home modification and caregiver education on the changes in activity performance and satisfaction level of persons with mild dementia in a home environment. Moreover, the role of an occupational therapist as a service provider in Korea for persons with dementia was discussed Methods: The participant of this study was an 84 year-old woman with Alzheimer’s disease. The independence, difficulty, and safety of the participant regarding her activity performance were assessed through an AHA. COPM was used to determine the meaningful activities for the participant. Based on the results, the target intervention activities were selected. Moreover, home modifications and caregiver education were determined as intervention methods according to the cognitive level of the participant, which was assessed through her ACLS. The outcome measures were collected post intervention and during a 6-month follow-up assessment. Results: The performance level of the activities, which showed a decline owing to cognitive impairment, increased after the intervention. The increase in independence, difficulty, and safety was maintained after 6 months. Activity satisfaction also improved throughout the intervention. Conclusion: Client-center home modifications and caregiver education improved the activity performance and satisfaction of the participant. Furthermore, occupational therapists are required to offer services to clients with dementia as a case manager.

(2024-04-24) Findley, Caroline; Grove, Dara; John, Andrea; Lenk, Lauren; Martinez, Adriana; Tinnin, Morémi; Chase, Anthony; Lee, Chang Dae; Department of Occupational Therapy, School of Health and Human Sciences
A thorough systematic analysis was conducted to find effective interventions for people with traumatic brain injuries (TBI) who are 18 years of age and older. This review gives an overview and discussion of 30 studies focused on various interventions classified into the following categories: group-based approach, memory and planning, social participation, and emotional and behavioral regulation. The objective of the rapid systematic review (RSR) was to search the literature and critically appraise findings to address what evidence is available regarding interventions to promote psychosocial wellness, executive functioning, and occupational engagement in adults with TBI. Technology and group-based approaches were effective in improving psychosocial outcomes, however within clinical research there is a lack of OTP researchers and interventions designed to address longevity of recovery.
Establishing OT’s Role in Addressing Sleep Disturbances for Autistic Children: A Rapid Systematic Review
(2024-04-25) Arnold, Logan; Bacon, Veronica; Conn, Sydney; Cowgur, Chloe; Metaxas, Nina; Mehringer, Jadon; Chase, Anthony; Lee, Chang Dae; Department of Occupational Therapy, School of Health and Human Sciences
This rapid systematic review examined the relationship between various interventions and sleep measures for autistic children and adolescents. Establishing this link can aid occupational therapists in understanding how to select and apply established interventions to practice. A variety of interventions were found within current literature to treat sleep disturbances including melatonin, non-melatonin pharmaceuticals, physical activity, behavioral and educational sleep hygiene, and sensory based interventions. The results indicated that all but the non-pharmaceutical interventions consistently yielded beneficial outcomes in decreasing sleep problems in the autistic children. However, these positive outcomes were briefly sustained once the studies ended. These findings suggest there is a trend within literature that sleep interventions have limitations when attempting to apply them to real-life cases. This dynamic highlights a gap between evidence-based outcomes that may improve sleep deficits in autistic children and the ability for these outcomes to be implemented in family’s homes. Occupational therapists have the potential to fill the gap and provide translational care to assist families in establishing routines backed by evidence. By improving sleep quality in this population, these guided interventions have the potential to improve the overall well-being and life satisfaction of children and their families.
Exploring autobiographical memory functions in Korean older adults: Development and application of the Korean version of Thinking About Life Experiences scale (TALE-K)
(2021) Park, Sangmi; Lee, Chang Dae; Kim, Tae Hui
Objective: The aim of this study was to develop a Korean version of the Thinking About Life Experiences scale (TALE-K) and to analyze the characteristics of autobiographical memory function (AMF) in community-dwelling older adults Methods: To develop TALE-K, a translation and back-translation procedure followed by an understanding test was performed. Then, a survey was conducted to examine the associations of AMF with psychosocial variables using TALE-K, Index of Well-Being (IWB), Meaning in life scale for older adults, Revised UCLA Loneliness Scale (RULS), Medical Outcomes Study Social Support Survey (MOS-SSS), Brief Resilience Scale (BRS). Results: Data from 75 community-dwelling older adults were used for the final analysis. The average scores of all three subscales of TALE-K were below 3 points (less frequent than occasionally). The correlation results showed that TALE-K total score was significantly associated with IWB and the Meaning in life scale for older adults. The multiple linear regression results presented that higher AMF was significantly associated with higher IWB, along with having siblings, higher meaning in life and resilience, and lower loneliness. Conclusion: Including a validation study of TALE-K, studies for understanding the characteristics of AMF in older adults using TALE-K are needed.
