Clinical Trial Summary

The specific study aims will be: 1. To examine the treatment effects of a new digital mirror therapy (MT) system versus a mirror box in patients with stroke by conducting a 4-group randomized controlled trial. 2. To examine the electrophysiological mechanisms of uni-mirror visual feedback (uni-MVF) condition with unimanual training mode, uni-MVF condition with bimanual training mode, and bi-MVF condition with bimanual training mode in the new MT system by EEG.


Description:

Part I: Validation of Treatment Efficacy of the New Digital MT System with Different MVF Conditions and Training Modes In this new MT system, 3 different types of MT in different MVF conditions and training modes can be provided: unilateral MVF with unimanual training mode (UM-UT), unilateral MVF with bimanual training mode (UM-BT), and bilateral MVF with bimanual training mode (BM-BT). In the part Ⅰ study, an estimated total of 80 patients with stroke will be recruited. In addition to the original rehabilitation interventions of patients, each participant will be randomly allocated to 1 of 4 intervention groups (i.e., UM-UT, UM-BT, BM-BT, or traditional MT using a mirror box) for 15-hour therapy sessions. Outcome measures will be administrated at pre-treatment, immediately after treatment, and at 1-month follow-up after treatment. Part II: Investigation of the Electrophysiological Mechanisms Underlying Different MVF Conditions by EEG Twenty stroke patients will be recruited for examining the brain electrophysiological mechanisms underlying different types of MVF and training conditions of this new system by using electroencephalography (EEG). Three experimental conditions, including UM-UT, UM-BT, and BM-BT conditions, will be conducted in the EEG study.

Study Design


Intervention

Behavioral:
Uni-MVF condition and unimanual training mode using the new MT system (UM-UT)
For the UM-UT group, the participants will be seated in front of the new MT system, and will be instructed to watch the real-time image reflection of movements of the non-affected arm and hand on the screen carefully. At the same time, the patients will need to imagine that the movements were performed by their affected arm and hand. In this group, only the non-affected arm and hand will need to perform the movements, but the affected one will not need to move.
Uni-MVF condition and bimanual training mode using the new MT system (UM-BT)
During the UM-BT, as similar as the first group (UM-UT), the participants will be also seated in front of the new MT system, and be instructed to watch the real-time image reflection of the non-affected arm and hand's movements on the screen carefully and imagine that the movements were performed by the affected arm. However, in this UM-BT group, the bilateral training mode is emphasized, and thus both arms and hands will need to move. That is, during therapy, the patient's affected arm and hand will be required to move at his/her best motor ability with the non-affected arm and hand at the same time.
Bi-MVF condition and bimanual training mode using the new MT system (BM-BT)
For the BM-BT group, the participants will be seated in front of this new MT system, and be instructed to observe the real-time image reflection of the non-affected arm and hand's movements transformed and superimposed on both arms and hands (i.e., bi-MVF), and to imagine that the movements were performed by both arms and hands. In this group, bi-MVF and bilateral training mode are emphasized, and thus both arms and hands will also need to move. The patient's affected arm and hand will be required to move as could as possible simultaneously.
Traditional MT using a mirror box
During traditional MT, the participants will be seated in front of a mirror box placed at their mid-sagittal plane. The affected arm and hand of the participants will be placed inside the mirror box, and the non-affected arm and hand will be in front of the mirror. As similar to the UM-UT group, the participants will be instructed to watch the mirror reflection of the movements performed by the non-affected arm and hand carefully and to imagine that the movements were performed by the a?ected arm and hand. In this group, the patient's affected arm and hand inside the mirror box will not need to move.

Outcome

Type Measure Description Time frame Safety issue
Primary Change scores of Fugl-Meyer Assessment The upper-limb subsection of Fugl-Meyer Assessment is a measure with sound psychometric properties to evaluate motor impairments. baseline (T0), at the end of 4 weeks of intervention (T1) , and 1 month after intervention (T2)
Primary Change scores of Chedoke Arm and Hand Activity Inventory The Chedoke Arm and Hand Activity Inventory is a reliable and validated measure to assess the independence of stroke patients to perform activities of daily living with an affected upper limb. baseline (T0), at the end of 4 weeks of intervention (T1) , and 1 month after intervention (T2)
Secondary change scores of Box and Block Test The Box and Block Test is a tool with sound reliability and validity to evaluate hand dexterity of stroke patients. baseline (T0), at the end of 4 weeks of intervention (T1) , and 1 month after intervention (T2)
Secondary change scores of Revised Nottingham Sensory Assessment The Revised Nottingham Sensory Assessment is a standardized measure with good reliability to assess sensory function in patients with stroke. baseline (T0), at the end of 4 weeks of intervention (T1) , and 1 month after intervention (T2)
