THE EFFECT OF MOTOR IMAGERY ON UPPER EXTREMITY FUNCTIONS IN STROKE REHABILITATION

THE EFFECT OF MOTOR IMAGERY ON UPPER EXTREMITY FUNCTIONS IN STROKE REHABILITATION: A RANDOMIZED CONTROLLED TRIAL

Stroke is one of the leading causes of mortality and disability worldwide. A proportion of individuals who experience a stroke fail to achieve the desired level of motor recovery in the affected upper extremity following rehabilitation, resulting in significant limitations in activities of daily living. After stroke, rehabilitation programs are essential to reduce disability and enhance functional outcomes.

This study aims to evaluate whether the addition of Motor Imagery (MI) to a standard rehabilitation program contributes to improvements in upper extremity motor function in individuals with stroke. MI is a mental practice technique in which individuals cognitively rehearse movements without physically performing them. Although the movement is not executed, the brain regions involved in the movement are activated.

Eligible participants will be randomly assigned to three groups. All groups will receive a standard physical therapy and rehabilitation program. The first group will receive only standard physical therapy and rehabilitation. The second group will receive, in addition to conventional therapy, 15 minutes of MI training three days per week, while the third group will receive 15 minutes of MI training five days per week. The total treatment duration for all groups is planned as 30 sessions.

Assessments will be conducted at baseline, at the end of the treatment period, and again at the 12th week. This study is based on the hypothesis that adding MI practice to a conventional upper extremity rehabilitation program after stroke will contribute to improvements in activities of daily living and functional recovery, and that these effects may be associated with the frequency of the intervention.

Study Overview

Detailed Description

Stroke is defined by the World Health Organization as a clinical syndrome characterized by focal or generalized neurological impairment of cerebrovascular origin lasting longer than 24 hours or resulting in death. Stroke is one of the leading causes of mortality and disability worldwide. Approximately 30% to 66% of individuals who experience a stroke fail to achieve satisfactory motor recovery in the affected upper extremity following rehabilitation; this condition constitutes a major source of disability and leads to substantial limitations in activities of daily living.

The majority of functional recovery is achieved within the first three months after onset. In the chronic phase, functional recovery is slower; however, neuroplastic changes continue to occur during this period. Following stroke, rehabilitation programs are essential to reduce disability. Upper extremity rehabilitation after stroke commonly includes range of motion exercises, stretching, strengthening exercises, neuromuscular facilitation techniques, neurophysiological approaches such as Brunnstrom and Bobath, and functional electrical stimulation.

Motor imagery (MI) and mental practice can be defined as continuous processes in which an individual attempts to simulate a movement using cognitive processes without physically performing the motor action. In other words, MI consists of the mental representation of a movement that is not actually executed. Through this process, it is aimed to acquire and optimize motor skills by generating a voluntary neural drive. MI does not require substantial economic investment and can be performed in any setting, as it does not necessitate specialized equipment. It is also considered safe, as it can be repeated multiple times without requiring significant physical effort.

In the existing literature, there is no clear consensus regarding the optimal duration and frequency of treatment. Although some authors suggest that the number of weekly treatment sessions and repetitions may influence motor learning, our review did not identify studies specifically addressing this issue.

Considering these factors, the present study aims to investigate the effects of MI on upper extremity motor function in individuals with stroke during the late subacute and chronic phases, and to determine whether these effects are associated with the frequency of the applied intervention. For this purpose, participants will be divided into three groups.

All groups will receive a routine conventional physical therapy and rehabilitation program in accordance with the clinical practice guidelines of the Turkish Society of Physical Medicine and Rehabilitation. The first group will receive only the routine conventional physical therapy and rehabilitation program. The second group will receive, in addition to conventional therapy, 15 minutes of MI training three days per week, while the third group will receive 15 minutes of MI training five days per week. The treatment program for all groups is planned as 30 sessions, each lasting 60 minutes.

For the MI intervention, a goal-oriented video recording will be prepared, including visually and auditorily guided representations of activities of daily living. These will include elbow flexion and extension, wrist flexion and extension, forearm pronation and supination, hand opening and closing, finger walking, thumb-to-finger opposition (touching the tip of each finger sequentially), reaching for an object, grasping and lifting it, drinking water from a bottle, combing hair, and opening a door handle. This video will be used as a supportive tool during MI training.

The motor imagery intervention will be conducted in a quiet room under the supervision of a physiotherapist and will follow the procedure below: the session will begin with whole-body relaxation. The participant will then watch the video depicting the target movement. Afterwards, the participant will be asked to close their eyes and imagine themselves performing the movement. The session will end with a return to a relaxed bodily state. This cycle will be repeated five times for each movement. During the procedure, participants will be instructed to focus on themselves and to avoid excessive stress and anxiety.

Assessments will be conducted at baseline, at the end of the treatment period, and at the 12th week.

Outcome Measure
Measure Description
Time Frame
Change in the Fugl-Meyer Assessment of Upper Extremity (FMA-UE) score from baseline assessment
Time Frame: Baseline, at 6 weeks (end of intervention), and at 12 weeks (follow-up)
The Fugl-Meyer Assessment for Upper Extremity (FMA-UE) is a stroke-specific, performance-based impairment index designed to assess motor function of the upper extremity. The scale evaluates movement, coordination, and reflex activity of the shoulder, elbow, forearm, wrist, and hand. Scores range from 0 to 66, with higher scores indicating better motor function
