Roboticky asistovaná terapie horní končetiny u pacientů se syndromem Guillain-Barrého (RAUL-Project)

Patients will receive upper limb neurorehabilitation training using a robotic exoskeleton administered by the therapist. The assistance provided by the device is adjusted based on the maximum force (as a percentage of the upper limb's weight) the robot needs to exert to assist the patient's movements. The computer-robot interface is designed to offer various exergames that require specific upper limb movements.

All movements performed by the patient using the exoskeleton will provide immediate audiovisual feedback on the computer screen. The training will consist of 20 sessions, with five 45-minute sessions per week.

Patients will undergo 20 session of 45 minutes each with an exoskeleton for upper limb rehabilitation. The assistance provided by the device is adjusted based on the maximum force (as a percentage of the upper limb's weight) the robot needs to exert to assist the patient's movements. Each session will include exercises designed to improve the range of motion (ROM) of the shoulder, elbow, wrist, and enhance hand coordination. The training parameters, such as difficulty level, duration, and visual stimuli, will be adjusted based on the patient's residual abilities. The selected exercises may involve movements of a single joint along one axis, combined movements of a single joint around 2 or 3 axes, selective exercises for the opening and closing hand, or multi-joint exercises. All exercises will be realized with audiovisual feedback.

Patients will undergo a neurorehabilitation intervention with a SHAM treatment under the guidance of the experimental therapist.

Patients will undergo 20 session of 45 minute of a neurorehabilitation intervention with a SHAM treatment under the guidance of the experimental therapist. This will involve passive mobilization using the exoskeleton for the upper limb, without any audiovisual feedback. They will not realize any active movement during the training.

THE FMAUE will be used to assess the change in the motor and sensory functions of the upper limb. The FMAUE included five domains: motor functioning, sensitivity, coordination, range of motion and pain. The score ranging from 0 to 66 points, a higher score corresponds to a better function of the upper limb.

The SF-36 will be used to assess the change in health-related quality of life. The SF-36 is organized into 8 different domains that are divided into physical components (Physical functioning, limitations due to physical problems, bodily pain and general perceptions of health status) and mental components (Social functioning, general mental health, limitations due to emotional problems and vitality). Each of the 8 domain scores, added together, is linearly transformed on a scale from 0 to 100, where 0 equals negative health and 100 equals positive health.

The mBI will be used to assess the change in the autonomy of patients during their activities of daily living. This scale has a score ranging from 0 to 100 points, a higher score corresponds to a better performance in the activities of daily living.

The ABILHAND will be used to assess manual dexterity. The ABILHAND is a questionnaire-based assessment tool that measures the difficulty a patient perceives in using their hands to perform manual operations and activities in daily living. It assesses upper limb functionality. It has nonlinear logit values ranging from 1.72 to -2.18.

The MRC will be used to assess muscle strength. The score ranges from 0 to 5 where 0 equals no muscle recruitment and 5 normal muscle force.

The NHPG will be used to assess fine manual dexterity. The NHPT consists of a square board with 9 pegs. At one end of the board are holes to insert the pegs, and at the other end is a shallow round plate to store the extracted pegs. The NHPT is administered by asking the patient to take the pegs from a container, one by one, and insert them into the holes on the board, as quickly as possible.

Grip strength will be assessed using a manual digital dynamometer. The maximum strength of the whole hand will be recorded for three times without feedback (with the patient sitting with his back to the monitor).

MMSE is a widely used psychometric tool in clinical settings to assess cognitive function. It is employed to detect cognitive impairments, monitor the progression of neurodegenerative diseases such as Alzheimer disease, and evaluate the severity of cognitive decline.

The test consists of a series of questions and tasks that assess various cognitive domains, including orientation in time and space, memory, attention, language, and the ability to follow simple commands.
