Stepping On leader training workshop
This is a 1.5-day face-to-face group-based training workshop conducted by master trainer Mr Xu Tianma (Principal Investigator)(PI) for allied health professionals in Singapore to become qualified Stepping On program leaders. It provides them with the basic knowledge of Stepping on program in preparation for setting up the group based Stepping On programs for community older adults. The participant will learn the key elements of the program and basic skills in facilitating the groups by participating in role play sessions during the workshop in a classroom setting. Ankle weights will be used to demonstrate the upgrading of exercises during the role play sessions.

Stepping On after Stroke leader training workshop
This is an add-on training workshop to any Stepping On leaders who have completed the 1.5 days Stepping On leader training. It will be a face-to-face group-based training by master trainer Xu. Additional components to Stepping On program will be shared at the half day workshop. Role play will be conducted by trainees and facilitated by the master trainer. No other physical equipment will be needed except ankle weights for muscle strengthening exercises during the workshop.

About master trainer
The Stepping On leader training workshops are facilitated by Mr Xu Tianma who is the PI for this research project. Mr Xu is an occupational therapist (OT) with more than 15 years of clinical experience working with older adults and stroke population. He teaches the OT degree program in Singapore Institute of Technology. He has conducted many training sessions to healthcare professionals in the areas of falls prevention, and stroke rehabilitation. He has successfully conducted two Stepping On Leader Training Workshops in March and April 2016. Mr Xu is currently pursuing his PhD study with University of Sydney under Professor Lindy Clemson, the main author of Stepping On program.

Staff involved:
Stepping On after Stroke program leaders
At least one OT and/or one physiotherapist(PT) from the participating rehabilitation center who have successfully completed the Stepping On facilitator training will be invited to join the half-day Stepping on after Stroke program leader training workshop. They will become Stepping On after Stroke program leaders in facilitating the program during the study.

Onsite clinical coordinators
There will be at least one therapist from each participating center to be appointed as onsite clinical coordinator to coordinate the participant recruitment and weekly sessions.

Invited guest speakers
External eye specialist and pharmacist will be invited as guest speakers to give a short session to stroke participants on common eye conditions in people after stroke in week 5 and medications and falls after stroke in week 6 respectively. The estimated time allocated for each expert will be 30 - 45 minutes.

Program outline
Pre-intervention evaluation will be conducted by the trained assessors at baseline using the series of standardized outcome measures. Each assessment session will last about one hour for each participant.

7 weeks intervention
-Weekly session will be scheduled on weekdays at a comfortable time slot that suits the participants and the center.
-Each group session will be run in an enclosed environment.
-There will be one 2-hourly group session facilitated by a qualified Stepping On after Stroke program leader in each week for 7 weeks.
-Each session consists of 20-30 minutes balance and strengthening exercises led by physiotherapist and facilitator.
-Domestic helpers or caregivers are encouraged to join the weekly session with the stroke participants.
-Each participant will receive one additional supervised community mobility practice session in a smaller group on top of the big group outing in week 5.
-Each participant will be provided with weekly program handouts and a communication booklet and weekly homework sheet at each session.
-The homework sheet will include Balance exercises & Strengthening exercises that each participant needs to tick daily once completed.

Two additional educational sessions will be conducted for family members and domestic helpers in the 1st and 7th week. Each educational session will last for 2 hours. OT will share the program overview, nature of stroke, community resources, common falls prevention strategies with all family members and helpers. OT will discuss with all participants about their supporting role in preventing their loved ones from falling in the community.

Follow-up home visit
OT will contact each participant to arrange for home visit 4-6 weeks after the 7th session. It aims to follow through of preventive strategies and assist with home modifications. Phone call will be a back-up option if home visit is not possible. All participants and program leaders will be invited to fill up the program evaluation survey form after the home visit.

Post-intervention reevaluation
-Same outcome measures will be conducted after the home visit.
-All participants and program leaders will be invited to fill up the program evaluation survey form after the home visit.

3-month booster session
-All participants will be invited to join the 2-hour booster group session at 3 months after 7th session.
-Facilitator and PT will review and conduct group exercise for 20 minutes.
-During the session, every stroke participant and family members or helper will share with each other how they benefited from the program, such as their self-coping and falls prevention strategies, as well as challenges faced since the completion of the 7 weeks program.
-Program evaluation survey will be issued to all participants again for their feedback after the booster session.

6-month follow-up
-All stroke participants will be followed up for a period of 6 months after 7th session.
-Each participant will be asked to keep track of their fall incidents (if any) during the 7 weeks program and 6 months after the 7th session.
-Each participant will be asked to fill up the monthly fall calendar provided by the researcher and submit it to the onsite clinical coordinator or the researcher at the beginning of the following month. Family members and helpers will be encouraged to assist the stroke participant in this activity. Researchers will remind them by phone call if the monthly fall calendar is not returned on time.

Fidelity check
The PI Xu will conduct the fidelity check in week 3-5 to ensure the interventions are carried out as planned. Feedback will be given to the program leaders in each center after each fidelity check.

Justification of sample size
Conducting 2 groups of Stepping On after Stroke program will be sufficient to test its workability and feasibility in the community rehabilitation settings in Singapore. The recommended number of elderly participants in each group for the original Stepping On program is 12. However, due to the complexity and disability of people with stroke, literature suggest that the appropriate number of stroke participants in each group is 6-8, which was further confirmed by local therapists and experts in the previous studies. Hence, we will include up to 8 stroke participants in each group. Together with their family members and domestic helpers, the total number of participants in this study will be up to 48 (see below breakdown).
Group 1:
Stroke participants: 8
Family members: 8
Domestic helpers: 8

Group 2:
Stroke participants: 8
Family members: 8
Domestic helpers: 8

Data analysis and interpretation
Pre-post evaluation
All assessors will be trained in using the following outcome measures by the researchers during the half-day Stepping On after Stroke program leader training workshop. The data collected from the pre-post outcome measures will be used for analysis.
The data collected from the pre-post outcome measures will be used to determine if the selected outcome measures are culturally relevant and applicable to detect any improvements or changes in balance, behaviour, safety strategies and community participation. Analysis will be using graphs and descriptive statistics to visualize any trends. The acceptance and usefulness of the measures will be determined.

Program evaluation survey
The specially designed Program evaluation survey forms for stroke participant and caregivers will be translated into Chinese with back translation method. All stroke participants, family members, domestic helpers, and program leaders will be invited to fill up the program evaluation survey form after the post-intervention home visit and 3-month booster session. General feedbacks on the program structure, outline, content, cultural relevancy, duration, timing, quality of program leaders, program location and challenges will be collected and analyzed.

Monthly fall calendar
All stroke participants will be asked to fill up the monthly fall calendar in bilingual languages (English and Chinese) throughout the 8 months study period. Each participant will submit their monthly fall calendar to the researcher or onsite clinical coordinator in the respective day rehabilitation center at the beginning of the following month. In the event of fall, the participant is asked to call the onsite clinical coordinator or the researcher. Details of the fall incidents (if any) including a number of falls, fall patterns, location and time of falls will be obtained and analyzed to calculate the fall rate and identify the common fall risk factors among the participants. The compliance rate, data accuracy, challenges faced and format of the monthly calendar will be analyzed for further improvement.

Summary

Brief summary

This feasibility study is part of the research project in developing Stepping On after Stroke (SOS) falls prevention program for community stroke survivors in Singapore, which aims to reduce their fall rate and increase community participation. Prior to this study, systematic review was conducted to identify the fall risk factors in community stroke survivors, followed by a series of qualitative studies to seek input from various stakeholders to determine the key elements of the SOS program. Thereafter, this new program will be piloted in two day rehabilitation centers (DRC). 

Pre-post design and prospective observational method will be used in this study, where 12-16 stroke clients, 12-16 family members and 12-16 domestic helpers will be recruited from two DRCs. This program will consist of 2-hour weekly session led by a trained Stepping On after Stroke program leader for 7 weeks; two educational sessions for family members and helpers; supervised community mobility practices in a small group; a post-intervention home visit and 3-month booster session. Stroke participants will be followed up for 6 months after week 7. 

Monthly fall calendar will be used to collect fall incidents during the study. Findings from pre-post outcome measures on stroke participants’ physical mobility, fall related self-efficacy, fall risk behavior, and community participation will be collected. The caregiver’s self-assessment of health and quality of life will be collected from the family and helpers before and after the program. 

Data will be analyzed to determine if the proposed measurement tools are culturally applicable and sensitive in detecting the changes in respective functions among participants. Program evaluation survey will be conducted with the participants and program leaders to find out their perspective of the usefulness and applicability of the program. All findings from the feasibility study will assist in further refining the program for a larger effectiveness trial.
