Detailed Description
This study is planned as a prospective randomized single blind controlled study. It was approved by the Ethics Committee of Ankara University, Faculty of Medicine and will be conducted in accordance with the Declaration of Helsinki. The study will include 38 stroke survivors who are admitted for rehabilitation at the Department of Physical Medicine and Rehabilitation, Ankara University Medical Faculty. Patients fulfilling the inclusion criteria of the study will randomly be divided into 2 groups as robotic group and control group. Random allocation software (RAS) program will be used to assign the patients to the treatment groups with "block randomization" method and to create the randomization scheme. In this single blinded study, all patients will be evaluated by the same physician (Dr. Merve Dayi). The physician will be blind to patient's assignment. Routine physical and rehabilitation medicine program including physical therapy and exercises, walking and balance training, and occupational therapy to improve activities of daily living will be given to all patients for a total of 6 weeks, 5 days/week, 1 hour/day. Robotic group will additionally receive upper extremity robotic training therapy with Armeo Spring V2.0 exoskeleton (Hocoma Inc.,Zurich, Switzerland) for 6 weeks, 5 days/week, 1 hour/day. The Armeo Spring is an adjustable suspension system for the upper limb that connects to virtual reality, which has settings with several degrees of complexity. The system is an exoskeleton that supports the patient's arm and magnifies any residual active movement of the hemiparetic arm in 3-dimensional space. The patients will receive 30 sessions of robotic therapy under the supervision of physiotherapists, who will adjust the patient's arm and hand in the device and select the virtual reality computer games according to the functional level of the patient's upper limb. All individuals participating in the study will be assessed before and immediately after the treatment and also 3 months at follow-up. Each assessment will include evaluation of cognitive functions, upper extremity motor functions, hand dexterity, upper extremity activities and daily living activities.
Statistical Analysis
As the primary outcome variable, the difference in cognitive functions measured by the Montreal Cognitive Assessment Scale (MoCA) between baseline and post-treatment will be used (Δ MoCA). Group sample sizes of 19 and 19 achieve 80% power to detect a Δ MoCA of 2.4 between robotic and control groups with estimated group standard deviations of 2.5 and 2.5 and with a significance level of 0.05 using a two-sided Mann-Whitney U test. Stratified block randomization will be used to ensure an equal number of subjects in each group. Educational status and age has been chosen as stratification variables. Difference between two groups for continuous variables will be evaluated by Student's t test. Mann-Whitney U test will be used to assess difference between two groups in terms of ordinal variables. The differences in proportions between groups will be compared by using Chi-Square. The repeated-measures ANOVA will be used to test within-group and between-group comparisons for continuous variables and interaction between them. p<0.05 will be considered statistically significant.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Robotic group
Robotic group will receive both routine physical and rehabilitation medicine program and additional upper extremity robot-assisted training by Armeo Spring.
Routine physical and rehabilitation medicine program, including physical therapy and exercises, walking and balance training, and occupational therapy to improve activities of daily living will last nearly 2 hours/day and robotic therapy one hour/day.
Routine PRM program and robotic therapy will be given through 6 weeks, 5 days a week (A total of 30 sessions of routine PRM program plus robotic therapy).
|
Upper extremity robot-assisted training will include facilitated shoulder flexion-extension, internal-external rotation, abduction-adduction, elbow flexion-extension, forearm supination-pronation, wrist flexion-extension, ulnar-radial deviation, hand finger flexion-extension movements by means of visual feedback with a 3-dimensional virtual environment in which the patient is asked to perform various tasks such as object reaching, grasping, holding, dropping activities by playing computer games. Routine physical and rehabilitation medicine program including physical therapy and exercises, walking and balance training, and occupational therapy to improve daily living activities will be given.

Active Comparator: Control group
Control group will receive only routine physical and rehabilitation medicine program.
Routine physical and rehabilitation medicine program, including physical therapy and exercises, walking and balance training, and occupational therapy to improve activities of daily living will last nearly 2 hours/day and will be given through 6 weeks, 5 days a week (A total of 30 sessions of routine PRM program only).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cognitive function
Time Frame: change from baseline at 6 weeks and at 18 weeks
|
Cognitive functions will be assessed by "Montreal Cognitive Assessment Scale (MoCA) " which evaluates visuospatial/executive functions, naming, memory, attention, language, abstraction and delayed recall.
Total score ranges between 0 and 30.
High scores are associated with better clinical outcomes.

Measure Description |
Time Frame |
---|---|---|
Upper extremity motor functions
Time Frame: change from baseline at 6 weeks and at 18 weeks
|
"Fugl - Meyer Upper Extremity Motor Rating Scale" will be used to evaluate the motor functions of the upper extremity.
It includes 4 subheadings (upper extremity, wrist, hand, coordination/speed).
Total score ranges between 0-66 with higher scores predict better outcome.
|
change from baseline at 6 weeks and at 18 weeks
|
Hand dexterity
Time Frame: change from baseline at 6 weeks and at 18 weeks
|
"Box and Block Test" will be used for assessing manual dexterity.
This test is composed of a wooden box divided into two compartments by partition and 150 blocks.
The patients are instructed to move as many blocks as possible for a period of 60 seconds.
Each hand is scored separately.
Higher scores are indicative for better manuel dexterity.
|
change from baseline at 6 weeks and at 18 weeks
|
Upper extremity function
Time Frame: change from baseline at 6 weeks and at 18 weeks
|
"The Motor Activity Log - 28 (MAG-28)" will be used to asses arm function.
This instrument is a structured interview intended to examine how much and how well the subject uses his/her more-affected arm.
Total score range between 0-5 and higher scores indicate better function.
|
change from baseline at 6 weeks and at 18 weeks
|
Activities of Daily Living
Time Frame: change from baseline at 6 weeks and at 18 weeks
|
"Functional Independence Measure (FIM)" will be used to evaluate the functional status of patients in activities of daily living.
The FIM's assessment of degree of disability depends on the patient's score in 18 categories, focusing on motor (self care, sphincter control, transfers, locomotion) and cognitive (communication, social cognition) function.
