Effects of Telerehabilitation-Based Motor Imagery Training on Pain in People With Multiple Sclerosis

Multiple sclerosis (MS) is a chronic, progressive, and demyelinating disease of the central nervous system that affects more than 2.5 million people worldwide and is more common in young adults. The most common clinical signs and symptoms include motor dysfunction, fatigue, spasticity, cognitive impairment, depression, decreased quality of life, bladder and bowel dysfunction and pain. People with Multiple Sclerosis (pwMS) show a wide range of pain symptoms, from acute pain symptoms to chronic pain symptoms. Pain is an important symptom in pwMS and is often associated with disability. Pain is a fairly common symptom in pwMS. The prevalence of pain in MS was found to be 63%. In addition, 30% of pwMS describe pain as their most severe symptom.

In the studies, it was found that motor imagery training, which is defined as imagining movement without revealing the movement in reality, is a training at the cortical level and reduces pain by creating positive effects on the impaired body schema perception. However, the effect of motor imagery training on pain in pwMS has not been investigated before.

For this reason, the aim of this study is to investigate the effect of telerehabilitation-based motor imagery training protocol, guidance of a physiotherapist, on pain, fatigue, anxiety, depression, quality of life and sleep quality in pwMS.

Persons who followed by the outpatient Multiple Sclerosis Clinic of Dokuz Eylül University Hospital will participate in the study. A total of 32 participants will randomly be divided into 2 groups. (1) Telerehabilitation-based motor imagery training, (2) Control group. Telerehabilitation-based motor imagery training group will individually receive telerehabilitation-based motor imagery training under the guidance of a physiotherapist for 8 weeks.

The first 2 weeks of the treatment period, will reserved for implicit motor imagery / lateralization training. It will be performed by the "noi group application" application that can be downloaded to the participants' mobile devices (smartphone or tablet). Lateralization training will be aimed at the initially evaluated areas of the participants (neck, back, shoulder, knee, hand/wrist, foot/ankle) that have a pain level of at least 30 mm according to the Visual Pain Scale (VAS). In the application, the participants will be asked to discriminant right and left with simple photographs of the painful areas determined at the beginning, and more complex photographs will be used as the training progresses. Participants will be asked to use the app 3 times a day. In each application session, the right / left discrimination of the region in the photograph will be requested within 5 seconds and 30 photographs will be shown for each painful region. Each session will last 2-3 minutes on average, depending on the number of painful areas of the participants. Controls will be made over the results sent to the e-mail address of the physiotherapist through the application. For 3rd to 8th weeks of the treatment period telehabilitation-based motor imagery training will be given to the participants individually, in synchronization, using the Google Meet videoconference platform, under the guidance of a physiotherapist. Participants will participate the treatment with their smart phones, tablets or computers that have an active internet connection and are suitable for meeting via videoconference. The duration of the sessions will last 20-30 minutes.
