Effects of Maximum Versus Minimum Supervised Telerehabilitation on Upper Limb Function in Post Stroke Patients

This single-blinded randomized controlled trial will compare the effects of maximum versus minimum therapist supervision during home-based telerehabilitation in stroke survivors with upper limb impairment. The study will examine whether the intensity of therapist supervision influences improvements in upper limb motor function, functional task performance, coordination, and proprioception. The study will be conducted over one year at MDL Rehabilitation FUCP and in participants' home settings. With the increasing demand for accessible and home-based stroke rehabilitation, this study aims to determine whether frequent therapist supervision provides additional benefits or whether a less supervised model can achieve comparable functional recovery.

A total of 30 stroke survivors aged 40-70 years will be recruited through purposive sampling. Participants will have experienced a stroke 3-24 months before enrollment and will demonstrate mild to moderate upper limb impairment, defined by a Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) score between 23 and 56. Eligible participants will undergo baseline assessment before being randomly allocated into either the maximum-supervision or minimum-supervision group. Randomization will help ensure an appropriate comparison between the two intervention approaches.

The rehabilitation intervention will be developed from a standardized pool of 50 pre-designed therapeutic exercises. This exercise pool will provide a structured range of activities addressing different components of upper limb recovery while allowing the program to be individualized according to each participant's baseline motor ability. Exercise selection and progression will be guided by the participant's initial FMA-UE performance and response to treatment. The intervention will follow a progressive sequence over the eight-week treatment period. During the first two weeks, exercises will primarily focus on range of motion (ROM), mobility, and controlled movement of the affected upper limb. As participants progress, the exercises will gradually incorporate more functional and challenging activities.

During weeks 3 and 4, the program will progress toward bimanual activities requiring coordinated use of both upper limbs. In weeks 5 and 6, greater emphasis will be placed on grasp-and-release activities to improve hand control, object manipulation, and functional use of the affected limb. During the final two weeks, exercises will advance toward fine motor activities requiring greater precision, dexterity, coordination, and selective hand movements. This staged progression from basic movement to increasingly complex functional activities is intended to provide an appropriate therapeutic challenge while supporting gradual improvement in motor control and task performance. Exercises will be selected from the established 50-exercise pool based on individual ability rather than applying an identical exercise sequence to every participant.

Participants in the maximum-supervision group will receive three 45-minute videoconference sessions per week for eight weeks, providing a total of 24 therapist-supervised sessions. During these sessions, the therapist will monitor exercise performance, provide verbal and visual feedback, correct compensatory movement patterns, and modify activities when appropriate. The therapist will also ensure that exercises remain suitable for the participant's functional level and fatigue tolerance. In contrast, participants in the minimum-supervision group will perform their prescribed 45-minute home exercise sessions independently three times per week for the same eight-week period. They will receive weekly therapist check-ins to review progress, address difficulties, and support adherence. Both groups will therefore complete an equivalent overall exercise schedule, while differing primarily in the amount of direct therapist supervision.

To maintain consistency between groups, all participants will receive the same exercise booklet and demonstration videos. They will be instructed to perform exercises within their individual fatigue limits and to follow the prescribed progression. Participants in the minimum-supervision group will maintain an exercise log to record their home practice, while therapist monitoring in the maximum-supervision group will provide more frequent oversight of exercise performance and adherence.

The effects of the intervention will be evaluated using established outcome measures. The Fugl-Meyer Upper Extremity Assessment will assess upper limb motor impairment and recovery. The Wolf Motor Function Test will evaluate functional task performance and upper limb use. Coordination will be assessed using the Comprehensive Coordination Scale, while proprioceptive function will be evaluated using the Thumb Localization Test. These measures will allow assessment of changes across motor recovery, functional performance, coordination, and sensory-motor control.

The study is expected to determine whether intensive therapist supervision results in superior outcomes compared with a minimally supervised home-based program. The findings may help establish an appropriate supervision model for telerehabilitation after stroke and support the development of practical, scalable, and cost-efficient rehabilitation programs that can provide structured upper limb training within the home environment.
