The number of faculty staff includes 10 full-time teachers, 8 adjunct teachers and 6 part-time teachers in the School. The faculty of the School is believed to be the best in the nation, either in terms of number or in terms of quality.
Dr. Lin’s primary research interest pertains to stroke rehabilitation, including comparative efficacy trials and applied translational research. Dr. Lin and colleagues have investigated task-specific rehabilitation (eg, constraint-induced therapy [CIT], bilateral arm training [BAT], and robot-assisted therapy [RAT]) for improving motor control and functional outcomes in stroke patients. His research has demonstrated domain-specific outcomes of rehabilitative therapies and task-specificity of brain plastic changes after interventions (eg, fMRI changes in response to different treatment regimens shown in the figure).
To clarify changes in motor control strategy after neurorehabilitation, Dr. Lin and colleagues have used kinematic analysis to identify specific changes in movement control after rehabilitation in terms of efficiency, smoothness, and preplanning. Extended research has been geared towards the study of benefits and adverse effects of stroke rehabilitation to project the profile of dose-effect relations.
The focus of my research is on developing a computerized adaptive testing (CAT) system of functional performance for patients with stroke. The CAT measurement system is used to help clinicians and researchers administer assessments in efficient and precise fashions.
Recently, I have constructed two CATs (balance and motor) which can be accessed at http://126.96.36.199/cat/
I have maintained a consistent interest in psychometrics and outcome measurements related to clinical research for patients with stroke. My long-term research goal is to develop a clinical excellence model to improve the effectiveness of occupational therapy for patients with stroke.
Sensory motor function in children with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD); the influence of pencil grip posture on handwriting performance in school-aged children; development of assessment tools for sensory motor function such as motor coordination, and sensory processing patterns; determinants of school participation of children with cerebral palsy (CP); predictors of quality of life (QoL) in children with CP and their caregivers; daily function in children with CP; cross-cultural comparison of daily function between American and Taiwanese children; risk factors of problem behaviors in preschool children with ASD; Longitudinal study of QoL in children with ASD; predictors of school participation in children with ASD.
The use of item response theory in developing assessment instruments to be applied in clinical practice has been prevailed for the past 10 years. Among three types of IRT models, Rasch measurement model was the most popular and useful one. One of my research interests is to apply the Rasch measurement in the refinement and development of the clinical assessments aiming to detect strengths and deficits of the clients we served. The ultimate goal is to enhance the adequacy of the treatment planning following the assessment procedure. We have examined several instruments developed by ourselves as well as developed by foreign countries using Rasch measurement model. We found that it not only offers benefits of converting the raw score from ordinal to interval level, it also provides information regarding the adequacy of the rating scale, the order of item difficulty and sensitivity of the scale in detecting the ability of the persons. In our studies, we found that Beck Depression Inventory-II, as applied in a group of persons with depression, was adequate as a unidimensional scale except for 4 items (publication 1). We also analyzed the Stigma Impact Scale, as used in a group of persons with diverse diagnoses (Schizophrenia, Depression, HIV/AIDS), of its construct validity. We found that it is a unidimensional scale with adequate rating scale structure (as shown below) and was sensitive to evaluate the change of the impact (publication 2 ).
The focus of my research is on developing a computerized adaptive testing (CAT) system for assessing functional performance and patient-reported outcomes in stroke patients. The CAT system is useful for clinicians and researchers to administer assessments in efficient and precise fashions. Recently, I and my colleagues have developed two CATs (balance and motor) which can be accessed at http://188.8.131.52/cat/. I am also interested in developing computerized tests for assessing cognitive functions. Two tests (spatial attention and short term memory) have been constructed. The psychometric validation of both tests is ongoing.
My ultimate research goals are achieving comprehensive assessments for both treatment planning and outcome measurement for stroke patients. Furthermore, such assessments can be completed in an efficient fashion. I strongly believe that such precise and efficient assessments will benefit patients, clinicians, and researchers.
Our research focuses on community-based occupational therapy interventions including assistive technology, environmental modification, and home-based therapy for elderly and persons with disabilities. The goals of the research work are to establish the intervention model, develop measurement tools, and validate the efficacy and effectiveness of those interventions. We have developed a radiographic method for measuring the spinal alignment in sitting and demonstrated the effects of a commonly used assistive device – lateral trunk support (LTS) in special seat improved scoliotic spinal alignment in individuals with spinal cord injuries. Recently, a cross-cultural version of the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) for measuring assistive technology user satisfaction in Taiwan was developed and validated.
The overall goals of our laboratory are to explore the work condition and quality of life and to study the effectiveness of the vocational rehabilitation for people with disabilities, as well as to develop evaluation tools for measuring workability of people with disabilities. Work is one of the major daily activities in most people’s life. In the past, we conducted few studies to gain insight into the health of massage practitioners and quality of life and work of people with spinal cord injury. As we know, impairment in cognitive and physical capacity is considered as a barrier to the execution of skilled tasks, especially for people with disabilities. We recent publish the reliability and validity results of a Functional Capacity Evaluation tool (Figure) and Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) used to measuring the physical and cognitive capacity of individuals with disabilities. We also finish the 3-year research in the effectiveness of the work programs for people with work injury. Preliminary data shows that individuals who participated in work programs were at increased rate of return to work. In the future, our research will focus on studying the effectiveness of the supported employment services for individuals with mental illness and developing a needs assessment tool for case managers in vocational rehabilitation.
Our research interest has been in the areas of biomechanics and human motion analysis. The focus of the recent studies was the investigation of the kinematic and kinetic strategies of the locomotor system during obstacle-crossing, with special interest in the prevention of falls in the elderly and patients who may have high risk of falls, including older people with knee osteoarthritis (OA) and highly functioning patients with stroke. Not only using the traditional kinematic and kinetic analyses, a novel approach, namely inter-joint coordination has been reported in our recently research on obstacle crossing. Inter-joint coordination may provide more information on how the central nervous system (CNS) organizes the various joints to perform functional activities.
Precise measurements of upper extremity function and activities of daily living in patients with stroke are essential for appropriate treatment planning, clinical decision-making, and research. I have been devoted to understanding the characteristics and the psychometric properties of the assessment tools in recent years, hope to assist therapists and researchers to recognize patients’ problems, select suitable assessment tools and provide effective treatment.
I am interested in using cognitive neuroscience approach to study the relationship between human behaviors and brain. My research program included several topics: 1. mechanisms underlying selective attention 2. conscious and unconscious perceptual processing 3. visual object recognition 4. motion perception in vision.
My research interests are in the areas of child’s motor development in terms of postural control, gross motor, and fine motor skills as well as longitudinal follow-up studies in high risk developmental population. The current ongoing project is to investigate preterm children’s longitudinal motor development and its important prognostic factors based on the ICF-CY framework. The information generated by the longitudinal inquiry will provide a multi-face scenario of change in adaptation to preemie population in Taiwan. The findings will improve practitioners’ and researchers’ insight to be awarded of the possible deficits in preterm children’s motor development and its risk factors to prevent further impairment.
According to the research done by the faculty and their clinical practice interests, specialty areas are divided into occupational therapy for physical disabilities, occupational therapy for psychiatric disabilities, and pediatric occupational therapy for pediatric patients. The teaching program covers services from acute care to the community-based practice. The students learn a comprehensive view of occupational therapy and gain practical experience in different service models.
