Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of study is to investigate a newly developed AI smartphone application's feasibility, usefulness in improving users' experience, effect on adherence, UL use and recovery after stroke. The study is a prospective randomized controlled trial (RCT) to compare the implementation of AMPLIFY, a self-directed UL programme for people with stroke in two modes of delivery- hardcopy manual versus the mobile application. Eighty people with stroke within 4 weeks of stroke will be randomly allocated to either the experimental group (smartphone app) or control group (hardcopy manual) to undergone four weeks of AMPLIFY program. To compare the clinical effects of delivery AMPLIFY program via smartphone app versus hardcopy manual, assessments will be done at three time points- pre-intervention, post-intervention and three months post-intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background To intensify practice to influence neuroplasticity to optimize UL recovery after stroke, it is important to empower people with stroke to perform self-directed UL therapy outside therapy. However, it has been found that increasing UL practice is often challenging with high level of inactivity found in people with stroke during rehabilitation. Traditionally, self-directed program has been delivered via hard copy manuals. Hardcopy manuals are often cumbersome and difficult to retrieve and handle, especially for those with moderate/severe UL impairment. Hence a more accessible format of exercise/activities instructions is needed. There is lack of reminders for people with stroke to keep up to prescribed exercise regime. This may affect adherence as some may not remember the prescribed practice sessions. Without immediate feedback of UL movement performed during self-practice, people with stroke may continue with compensatory movement performance without correction. This may in turns hinder UL recovery.

The aim of this study is to overcome these challenges by developing an AI-powered interactive smartphone application called AMPLIFY app that enables prescription and progression of exercises/functional activities, while offering immediate feedback on UL movement performed, real-time logging and monitoring of adherence through virtual platform. The inherent interactive nature of app offers features to engage and remind people with stroke to use their paretic UL. This app offers remote monitoring and supervision by therapists without need for actual therapists' physical presence. As the AMPLIFY app is a newly developed AI-powered interactive smartphone application, it is important to investigate the app's feasibility, usefulness in improving users' experience, effect on adherence, UL use, recovery and cost-effectiveness.

Aim:

To Investigate:

1. Feasibility of AMPLIFY app in completing self-directed UL therapy programme
2. Usefulness of AMPLIFY app in improving the users' experience in self-directed UL therapy programme performance
3. Effectiveness of AMPLIFY app in increasing adherence in self-directed UL therapy programme performance
4. Effectiveness of AMPLIFY app in increasing UL use, confidence and improving recovery after stroke
5. Cost-effectiveness of AMPLIFY app in reducing the need for clinical review in self-directed UL therapy programme performance

Methods:

The study is a prospective randomized controlled trial (RCT) to compare the implementation of AMPLIFY programme in two modes of delivery- smartphone app versus hardcopy manuals to investigate the aims mentioned above.

People with stroke who fit into the inclusion and exclusion criteria will be invited to participate in the study via informed consent by the research assistant (RA)/ study team members. Once the informed consent has been given by the participants, the participants will undergo the pre-intervention assessment. After the pre-intervention assessment, the participants will be randomised either to the experimental group (AMPLIFY programme via the smartphone app) or control group (AMPLIFY programme via the hardcopy manuals). The intervention of experimental and control arms are described below. Both groups essentially undergo the same AMPLIFY programme but via different modes. Time points of assessment: pre-intervention, post-intervention and post-3months intervention assessments.

Experimental arm Assigned intervention The AMPLIFY Programme will be delivered via smartphone application with two levels. Level 1 is catered for people with stroke with Action Research Arm Test (ARAT) score \<34, while Level 2 is catered for people with stroke with ARAT score \>=34. Level 1 consists of six warm up exercises, six strengthening exercises and ten functional activities. Level 2 consists of three warm up exercises, four strengthening exercises, nine hand coordination and dexterity exercises, and ten functional activities. Five to six exercises (including at least one functional activity) will be prescribed to the stroke participants for each session to be performed independently or with the help of caregiver. Stroke participants are to performed the exercises/functional activities three sessions per day (i.e. morning, afternoon, evening) and for six days per week. In addition, the stroke participants are to use their paretic UL to perform the functional activities prescribed to them whenever needed throughout the day. The AMPLIFY programme will last for four weeks. If the stroke participants are discharged before the AMPLIFY programme ends, the participants will continue with the programme at home with the reviews being performed by the therapists via tele-rehabilitation. Frequency of reviews for the experimental group will be as follows: Week1 (2x); Week2 (1x); Week3 (x0); Week4 (x1).

Control arm Assigned intervention The AMPLIFY Programme consists of two booklets (Booklet 1 and Booklet 2). Booklet 1 is catered for people with stroke with ARAT score \<34, while Booklet 2 is catered for people with stroke with ARAT score \>=34. Booklet 1 consists of six warm up exercises, six strengthening exercises and ten functional activities. Booklet 2 consists of three warm up exercises, four strengthening exercises, nine hand coordination and dexterity exercises, and ten functional activities. Five to six exercises (including at least one functional activity) will be prescribed to the stroke participants for each session to be performed independently or with the help of caregiver. Stroke participants are to performed the exercises/functional activities three sessions per day (i.e. morning, afternoon, evening) and for six days per week. In addition, the stroke participants are to use their paretic UL to perform the functional activities prescribed to them whenever needed throughout the day. The AMPLIFY programme will last for four weeks. If the stroke participants are discharged before the AMPLIFY programme ends, the participants will continue with the programme at home with the reviews being performed by the therapists via tele-rehabilitation. Frequency of reviews for the control group will be as follows: Week1 (3x); Week2 (2x); Week3 (x1); Week4 (x1).
