## Body

## 1. Introduction

Stroke is a disease that causes temporary or permanent loss of function due to blockage or rupture of blood vessels in the brain, and physical, cognitive, and mental aspects of aftereffects cause restrictions on independent daily life [1]. About 75% of stroke patients show disabilities in independent daily life abilities [2]. If dependence on daily life continues, there is a possibility that interpersonal relationships and the quality of life may deteriorate due to helplessness and depression [3].Hospitalization for a considerable period after stroke is the most common approach for postoperative rehabilitation or intensive care for acute patients, and institution-based rehabilitation (IBR) provides expert-centered services for rehabilitation. However, this approach has limitations due to systematic discharge preparation, insufficient community integration procedures, lack of information on community services, and poor access to community services [4–6].In Korea, it was recommended that community-based rehabilitation (CBR) health centers organize community early adaptation programs, rehabilitation programs for the disabled, assistance device support, and health examination support programs for the disabled. CBR managers should classify the people with disabilities into different groups based on their ability for activities of daily living and quality of life, integrate and provide community public and private resources for the health care of the people with disabilities, and continuously monitor health state to meet the needs of the disabled [7].When providing rehabilitation in the community, occupational therapists have played a key role in evaluating and mediating daily life activities, evaluating and modifying residential environments, educating assistive device, and connecting community resources with stroke patients [8–11].In the case of activities of daily living, a previous study showed that one of the most effective ways is to directly observe occupational performance and educate task directly [12]. In order to reduce barriers in home environment, the home environmental modification was effective in aiming to change the location of the home structure and improve the ability of the subject [13]. It has been reported that it is effective to provide integrated and personalized interventions and provide information on available community resources according to the needs and functions of the education of the stroke patient’s guardian [14]. However, despite the growing need for occupational therapy other than hospitals, the participation of occupational therapists is limited due to the lack of legal grounds, poor working conditions, and payment systems. Therefore, it is timely to generate evidence by conducting a single target study that takes into account the individual characteristics of the stroke patients and the community environment.In previous studies, it was difficult to understand in detail each report on the results of daily life performance intervention through task-oriented methods, home environmental modification, guardian education on related diseases and interventions, and information on available community resources. In the clinical setting in the real world, interventions are applied integrally rather than individually, so it is important to investigate the roles and responsibilities of the occupational therapists by integrating and applying each intervention into occupation-based community interventions. The process of designing and analyzing occupation-based community intervention as a single subject design for people with disabilities after stroke can be an important process to suggest the direction of development of the study.According to these needs, occupation-based community rehabilitation is necessary to improve the daily life and quality of life of people with disabilities after stroke. The purpose of this paper is to investigate whether occupation-based community rehabilitation is effective in improving the daily life ability and quality of life of people with disabilities after stroke using a single subject design research.


## 2. Methods

This study investigated the effect of occupation-based community rehabilitation on the activities of daily living and health-related quality of life of people with stroke living at home.


### 2.1. Research Design

The A-B-A design was used as a single-subject research design. In this paper, we recruit participants for baseline phase A, intervention phase B, baseline phase A’, and follow-up phase. The period of the study was 17 weeks from April to August 2020. This paper was reviewed and approved by the Yonsei University Wonju Campus Biomedical Review Committee (YUWIRB). It was performed prior to conducting the study (approval number: 1041849-202001-SB-001-02).


### 2.2. Participants

The study participants were collected and analyzed from three people with severe disabilities (grades 1 to 3 for disability) living at home after stroke. Participants in this study were recruited according to the selection and exclusion criteria among people with stroke registered in the CBR project at the public health center for four weeks. The selection criteria included (1) with a score of ≤49 in the Modified Barthel Index (MBI) or with a score of <0.660 [7]; (2) those who have passed more than 6 months from the date of stroke; (3) a person diagnosed with a stroke by a specialist; and (4) those who understood and agreed to the purpose of the study were included. The exclusion criteria included (1) people with no guardians or other overlapping disabilities; (2) people who participated in other rehabilitation studies or drug experiments; and (3) people who could not communicate were excluded.

## 3. Measures

### 3.1. Modified Barthel Index (MBI)

The MBI was used as a tool to evaluate functional changes in stroke patients and to evaluate daily life behavior independence, and in 1989, Shah et al. [15] modified and supplemented the Barthel Index to evaluate daily life activities of chronically ill patients, and its validity and reliability have been proven [16]. MBI consists of a total of 10 items, 7 items for self-care index and 3 items for mobility index. Evaluation is conducted through guardian investigation or observation. The total score range is from 0 to 100, with a total score from 0 to 24, severity from 25 to 49, a middle from 50 to 74, a middle from 75 to 90, and a minimum from 91 to 99.


### 3.2. EuroQol-5 Dimension (EQ-5D)

The EQ-5D, developed by EuroQol Group, is a measurement tool for overall health and is evaluated in the form of a subject survey. EQ-5D is an indicator of health-related quality of life, which can be used to evaluate nondisabled and health-related quality of life as well as disabled people and is expected to identify vulnerable groups along with health policy evaluation [17]. It consists of a total of five areas: mobility, self-management, daily activities, pain/comfort, and anxiety/depression. Health-related quality of life scores are calculated from 1 to -1 by applying weights to each value measured for each domain. Complete health status is 1 point, and health status worse than death is -1. Health-related quality of life scores were calculated by applying weight calculation equations according to Lee et al. [18].


### 3.3. Assessment of Motor and Process Skills (AMPS)

AMPS is a standardized tool centered on subjects to evaluate motor skills and process skills, which are observed during daily life activities, rather than just evaluating the cognitive or physical damage of stroke clients [19]. It consists of a total of 7 items, divided into positioning, maintaining objects in hands, moving oneself and objects, continuing performance, applying knowledge, organizing space and objects, and controlling performance. Each AMPS technology item is scored on a four-step classification basis, and each step is classified as 4=competent, 3=questionable, 2=ineffective, and 1=severely limited occupational performance technology. As a result of the query of occupational performance, the raw score of each technical item is entered into the Occupational Therapy Assessment Package (OTAP) software provided by CIOTS, and the OTAP software considers the evaluator’s roughness, task difficulty, and item difficulty. The ability ranges from -3.0 to 4.0, and the ability to live without help in the community is based on 2.0 in athletic skills and 1.0 or more in processing skills. The clinically significant change in competency is 0.3 to 0.4, and the statistically significant change is 0.5 or more, which is interpreted as an improvement in occupational performance. AMPS inspection-reinspection reliability is 0.81 and 0.71 when only one task is performed, and the areas of exercise technology and processing technology are 0.91, and 0.85, respectively, showing higher reliability in two or more tasks [20].

AMPS inspection-reinspection reliability is 0.81 and 0.71 when only one task is performed, and the areas of exercise technology and processing technology are 0.91, and 0.85, respectively, showing higher reliability in two or more tasks [20].


## 4. Procedures

### 4.1. Baseline Phase A

During 5 sessions in three weeks in baseline phase A, the researcher dropped in on each participant’s home. The researcher observed the difficult and good activities chosen by the participants for 15 to 20 minutes and observed and recorded changes in the frequency of occupational performance by session. The participants signed and complied with the occupation contract before starting the task, and the task was completed after 5 minutes per occupation. MBI, EQ-5D, and AMPS were evaluated before baseline phase A.


### 4.2. Baseline Phase B

During 14 sessions in seven weeks in intervention phase B after the end of baseline phase A, researcher visited each participant’s home for the experiment. In the first session, preevaluation results were explained, and individual customized methods were trained for participants and caregivers. The contents of the education consisted of analyzing the daily life observed in advance, revising and proposing in a beneficial direction to improve effective daily life and occupational performance ability, and presenting tasks to improve daily life ability. The task was performed daily like a routine habit, and the participants recorded the task in the task notebook and delivered it to the researcher to receive feedback every session. MBI, EQ-5D, and AMPS were evaluated after baseline phase B.


### 4.3. Baseline Phase A’

During 5 sessions in three weeks in baseline phase A’, in the same way as in the baseline phase A, the researcher called on the participant’s home to observe the participant’s daily life performance, and in the final term, the participant’s future was consulted.


### 4.4. Follow-up Phase

In order to find out whether occupational-based community rehabilitation affects the daily life and quality of life of the disabled, a follow-up phage was conducted four weeks after the baseline A’. MBI, EQ-5D, and AMPS were evaluated in follow-up phase.

## 5. Independent Variable (Occupational-Based Community Rehabilitation Program)

This study used the occupation-based community rehabilitation program to improve the daily life and quality of life of people with stroke. Occupation-based community rehabilitation program consisted of task-oriented methods and feedback, home environmental modification, related information and education, and linking local resource.


### 5.1. Task-Oriented Methods and Feedback

In this study, the task-oriented approach is a training method focusing on special functional tasks that combine musculoskeletal or nervous systems and provides the participant’s occupation-based daily life as a task rather than repeatedly practicing normal patterns. In order to build tasks based on the occupation of each participant, the researcher prioritized meaningful activities for each topic according to OTIPM. However, if the participant performed the task for the first time or failed to perform it independently, it was possible to learn how to perform the task accurately by referring to the error-free fourth stage of learning by Thivierge et al. [21]. The task difficulty and the amount of help changed according to the participant’s degree of occupational performance.


### 5.2. Home Environmental Modification

Home environmental modification was performed to improve participants’ activities of daily living. After checking the participants’ spatial environment, the researcher changed the location of the structure and installed tools to prevent safety accidents to lower environmental barriers and increase convenience [22]. If necessary, it was proceeded through a contract with the lessor. The researcher applied and modified it to suit the participants to improve the performance of daily life in the changed family environment during the study period.


### 5.3. Related Information Education

Local community information and medical welfare resources tailored to the characteristics and needs of the participants were provided, and if necessary, they were directly linked to local resources. The linkage of local resources was able to meet the complex needs of medical welfare targets by identifying the complex needs of the participant s and finding and linking community services accordingly. The researcher checked the socioeconomic aspects and public systems of the participants to ensure that they were fully utilized and communicated with the available local resource managers to link them with the consent of the participants.


### 5.4. Local Resource Linkage

Researchers educated participants and caregivers on stroke-related information to enhance their understanding of stroke. This training was provided to individuals by referring to the health information bulletin board data distributed by the Central Health & Medical Center for Persons with Disabilities and the National Rehabilitation Center.


### 5.5. Task Fulfillment Rate

The researcher provided task notes to identify participants’ difficulties in performing tasks. Referring to this, the task fulfillment rate was analyzed. As a result of calculating based on the intervention period, the task fulfillment rates each among the 1, 2, and 3 participants were 95%, 100%, and 97%.

## 6. Dependent Variable

### 6.1. Session-Dependent Variable (Frequency of Occupational Performance Skill Change)

In this study, based on the AMPS skills definition used by Fisher and Bray Jones [20], the occupational performance skills were operatively defined based on the three techniques of coordinates, sequences, and heeds. Two occupational therapists with more than five years of clinical trials recorded the frequency of occupational performance that decreased or effectively showed physical effort and conducted occupational performance analysis.As shown in Table1, the operational definitions of occupational performance skills are listed.Table 1

## 11. Discussion

The study was aimed at investigating the effects of occupation-based community rehabilitation on activities of daily living and health-related quality of life of people with disabilities after stroke at home. The purpose was to observe and analyze the activities of daily living of the participants for each session to observe changes in their occupational performance, to evaluate their activities of daily living and quality of life before and after intervention, and to understand their applicability to community-based rehabilitation.As a result of applying occupation-based community rehabilitation, it was confirmed that all participants’ activities of daily living and quality of life improved. In the case of MBI conducted during the pre-, post-, and follow-up periods, to minimize errors caused by interviews in the form of questionnaires, the performance of the remaining eight items excluding urine and fecal activity was directly observed and the trend of change was investigated. Plans could be made based on the participation’s occupation, and activities of daily living scores were improved in all participants. In particular, in the case of participant 2, the use of the toilet has improved significantly from 2 points to 10 points. The reason for the improvement was that although he received total help from his caregiver due to fall anxiety, he was able to reduce anxiety, perform tasks with appropriate level, and acquire occupational skills.This result is consistent with previous studies that show that participation’s occupation-based methods improved their activities daily of living more than repeatedly learning normal patterns of stroke patients [23].AMPS scores were expressed in logits, and changes powerful than 0.3 logits were clinically significant. As explained by the AMPS evaluation results, participants 1, 2, and 3 improved logit motor scores of 1.2, 1.6, and 1.1 and process scores of 0.8 points, 1.3 points, and 0.9 points, respectively. Coordinates, sequences, and heeds were improved in all participants. There are many studies showing that occupation-based community rehabilitation improves occupational performance [2, 6, 9, 24, 25].The increase in activities of daily living of stroke patients and health-related quality of life are highly related, so it is necessary to examine them together. EQ-5D allows screening of participation’s quality of life by Kang et al. [17]. All participants were found to have improved the EQ-5D. Participant 3 changed all items related to mobility, self-management, daily activities, and pain/inconvenience, and the postevaluation result was evaluated as 0.72 points, improving through occupation-based community rehabilitation. In this study, it was found that occupation-based community rehabilitation is important in improving the activities of daily living and health-related quality of life of stroke participants.


## 12. Limitations and Future Research

Since this study has a small number of cases, the correlation between each evaluation should also be studied. In addition, rehabilitation service variables other than occupation-based community rehabilitation were not controlled. There is a possibility that there has been a change in the overall lifestyle of the participant, the resulting good habits, and the influence of daily life. In future research, various data analyses using wearable devices, or the Internet of Things (IoT) should be combined to redesign the subject’s lifestyle.


## 13. Conclusion

Through this study, it was possible to increase the independence of daily life and improve the quality of life related to health by applying occupational-based community rehabilitation to people with disabilities living at home after stroke. The occupational-based community rehabilitation consisted of a series of processes, including an occupational therapy intervention process model.The results of this study are as follows.First, after applying occupational-based community rehabilitation, the activities of daily living of all participants was improved, and the degree of independence of daily life improved.Second, the applications for occupational community rehabilitation have been proven to have an crucial effect on the health-related quality of life of all participants.Third, after the occupational community rehabilitation was applied, the quality of occupational performance improved. All three items performed by all participants made realistic changes possible. After the intervention phase was over, occupations were even well maintained.
