Study Overview
=================
Brief Summary
-----------------
Comparison of Upper Extremity Robotic Rehabilitation Efficiency with Conventional Rehabilitation in Patients with Hemiplegia after Cerebrovascular Event

Detailed Description
-----------------
The aim of this single-blind randomized prospective study is to find out whether including robotic therapy in addition to conventional rehabilitation program has an effect on quality of life, motor function and activities of daily living of the hemiplegic patients. Hemiplegic patients diagnosed by anamnesis, physical examination and radiological analysis, which have been referred to the outpatient clinic of Ege University Faculty of Medicine Department of Physical Therapy and Rehabilitation between April 2016 and April 2019 have been taken to the study. The demographic and clinical data of the patients were recorded and they were randomized into 2 groups. 17 patients assigned to the robotic rehabilitation group (Study group) receiving robot-assisted rehabilitation in addition to conventional treatment and 20 assigned to the conventional rehabilitation group (control group) receiving only conventional therapy completed the study. Robotic-based rehabilitation given additionally was arranged to be 30-45 minutes, 5 days per week for 4 weeks. All patients were assessed at the beginning of therapy and at the end of 4th week with Brunnstrom stages of motor recovery, Fugl Meyer Assessment (FMA), hand grip strength, Purdue peg test, Minnesota manual dexterity test, Modified Ashworth Scale (MAS) , Functional Independance Measure (FIM), Stroke Specific Quality of Life Scale (SS-QOL), Nottingham Extended Activities of Daily Living (NEADL) Scale, Montreal Cognitive Assessment (MoCA), Center for Epidemiological Studies Depression Scale (CES- D). In the study, improvements in motor function scores, spasticity, general functioning, activities of daily living, cognitive assessment scale are better in robotic group when compared with control group but this difference was not statistically significant (p>0,05). The investigators have found statistically significant improvement in CES- Depression scale in robotic group compared with control group (p=0,018). Significantly improved motor function gains are observed before and after the treatment in both groups being better in the robotic group however no significant differences were observed between the groups after the treatment. Robotic rehabilitation provides a favorable alternative bringing slight benefits, and also advantageous in terms of work power and psychological recovery so robotic rehabilitation addition to conventional neurological rehabilitation is effective and useful in patient management after stroke or cerebrovascular events.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline hand grip strength at 4th week. | Hand grip strength was measured using a hand dynamometer device(Jamar® Hand Dynamometer - Hydraulic - 200 lb Capacity). The measurements were recorded in kilograms. The higher scores indicates better outcome in hand grip strength. | Up to 4 weeks | 
| Change from baseline hand functions (Minnesota manuel dexterity test) at 4th week. | Manual Dexterity Test is a widely used test which measures the capacity for simple but rapid eye-hand-finger movement. This test includes two parts. The 'placing test' requires the patients to place 58 discs with a diameter of 3.5 cm in the spaces of another set of the same dimensions .The length of the sets requires a wide range of shoulder movements.The 'hand turning test' requires the patient to remove the discs from one set and place them in another, or to reinsert them by removing and turning them. This test was performed for the affected (hemiplegic side) upper limb of the patient (right or left) and the result was recorded in 'seconds'. Short periods show that the result is better. | Up to 4 weeks | 
| Change from baseline hand functions (Purdue peg board) at 4th week. | The Purdue Pegboard Test is a neuropsychological test of manual dexterity and bimanual coordination. The test involves two different abilities: gross movements of arms, hands, and fingers, and fine motor extremity. This test consists of a board with holes and pins that can be placed on them , also washers and nuts that can be attached to the pins. The patient is asked to insert as many pins as possible into the holes in 30 seconds in a straight row using his right hand.The same is then repeated for the left hand. Finally, by giving 1 minute time, it is passed to the stage where the patient inserts pins, nuts and washers by using two hands.The total score of these 3 stages gives the test score. The higher scores in this test shows better results. | Up to 4 weeks | 
| Change from baseline spasticity (Modified Ashworth Scale (MAS)) at 4th week. | The Modified Ashworth Scale is the most universally accepted clinical tool used to measure the increase of muscle tone. This scale is a numerical scale that grades spasticity from 0-4, with 0 being no resistance and 4 being a limb rigid in flexion or extension. The greater scores show increased spasticity and worse results. | Up to 4 weeks | 
| Change from baseline neurophysiological development (Brunnstrom stage) at 4th week. | The Brunnstrom Approach sets out a sequence of stages of recovery from hemiplegia after a stroke, emphasising the synergic pattern of movement which develops during recovery. It consists of six stages assessed separately for the upper limb, hand and lower limb. The higher scores show recovery and better results. | Up to 4 weeks | 
| Change from baseline motor function (Fugl Meyer Assessment (FMA)) at 4th week. | Fugl-Meyer Assessment (FMA) scale is an index to assess the sensorimotor impairment in individuals who have had stroke. The FMA motor assessments for the upper extremity consists of four subsections ( upper extremity, hand wrist, hand, speed/coordination). The total score ranges from 0 to 66, higher scores showing better motor function. | Up to 4 weeks | 
| Change from baseline general function (Functional Independance Measure (FIM)) at 4th week. | The Functional Independence Measure (FIM) is an 18-item measurement tool that explores an individual's physical, psychological and social function. Tasks that are evaluated using the FIM include six self-care activities, bowel and bladder control, transfers, locomotion, communication and social cognition. It is used to assess and grade the functional status of a person based on the level of assistance he or she requires. Grading categories range from total assistance with helper(score 0) to complete independence with no helper(score 7). The total score that can be obtained from this scale varies between 18-126, higher scores showing better results. | Up to 4 weeks | 
| Change from baseline quality of life (Stroke Specific Quality of Life Scale (SS-QOL)) at 4th week. | The Stroke Specific Quality Of Life scale (SS-QOL) is a patient-centered outcome measure intended to provide an assessment of health-related quality of life (HRQOL) specific to patients with stroke. SS-QOL contains 49 items and 12 fields; mobility, energy, upper limb function, work / production, mental state, self-care, social roles, family roles, vision, language, thinking and personality. Each field consists of at least 3 items, and each item is evaluated on a 5-point Likert scale. Higher scores reflect better function. The total score that can be obtained from SS-QOL varies between 49-245. | Up to 4 weeks | 
| Change from baseline quality of life (Nottingham Extended Activities of Daily Living (NEADL)) at 4th week. | The Nottingham Extended Activities of Daily Living (NEADL scale) comprises 22 questions to measure the independence in the following areas of daily living: mobility, kitchen, domestic and leisure activities. The total score varies between 0-66. Higher scores show better outcome. | Up to 4 weeks | 
| Change from baseline cognitive state (MoCA test) at 4th week. | The Montreal Cognitive Assessment (MoCA) is a brief 30-question test that takes around 10 to 12 minutes to complete and helps assess people for cognitive impairment. Different cognitive functions are evaluated with MoCA. These are attention, memory, concentration, executive functions, language functions, visual structuring skills, abstract thinking, computation and orientation. The score varies between 0 and 30 points and patients who get 21 points and above are considered normal. Higher scores indicate better results. | Up to 4 weeks | 
| Change from baseline emotional state (CES-depression test) at 4th week. | CES-depression test is a quick self-test, consisting of 20 items that measure depressive feelings and behaviours during the past week and one of the most common screening tests for helping an individual to determine his or her depression quotient. With the four-dimensional structure of the scale, depressive symptoms, positive effects, somatic symptoms and difficulties in interpersonal relationships were aimed to be measured. Score ranges from 0 to 60, and high scores indicate depression. | Up to 4 weeks |
