Exergame and Robotic Therapy Impact on Tenascin-C and Functional Outcome on Stroke Patients

1, Research design This research is an experimental study with a randomized controlled trial research design.

2\. Study Setting The research will be carried out among post-stroke patients at two teaching hospitals and one physical rehabilitation center in Makassar

3\. Procedure

a. Standard Rehabilitation Comprehensive medical management and rehabilitation of disabilities caused by stroke through the neurorehabilitation approach with the aim of optimizing recovery and or modifying existing remaining symptoms so that stroke people are able to carry out functional activities independently, can adapt to the environment and achieve quality life

b. Exergame Physical exercise of the entire body carried out through active video games that require gross motor skills, visual-spatial coordination, balance, and energy expenditure that are proportional to the intensity of moderate physical activity

c. Robotic Therapy Mirror therapy intervention uses the help of robot exoskeletal to move the sick side. A set of mirror therapy exercises, using Syrebo robotics, using 1 set of Activity Daily Living (ADL) training during therapy, and using a mirror that will reflect a healthy side shadow.

4\. Time frame the procedure will be conducted in parallel three times per week for a total of six weeks, with two measurements before and after six weeks of training

5\. Outcomes

1. motoric ability of upper extremity using Fugl-Meyer Assessment for Upper Extremities (FMA-UE) 2. Dexterity, coordination and response of finger using the Nine Hole Peg Test (NHPT) 3. Hand motor strength with Handgrip dynamometer 4. Level of Tenascin-C in blood serum before and after

6\. Case definition

a. type of stroke determined by radiology imaging b. phase of stroke (acute, sub-acute or chronic) c. cognitive ability measured using mini-mental state examination (MMSE) d. Spasticity measured by the Modified Ashworth Scale (MAS)

7\. Procedure

a. The data collected is primary data obtained in accordance with the inclusion criteria.

b. Samples who are willing to become research subjects will undergo interviews, physical examinations, FMA-UE-Hand Motor Domain, handgrip and NHPT examinations. The interview questionnaire in this study will contain a list of patient identities including name, age, marital status, address, educational history, employment history, history of stroke, cognitive examination (MMSE), and self-reported visual ability.

8\. Measurement tools

1. The FMA-UE-Hand Motor Domain scoring system is used to evaluate upper extremity motor function in patients with neurological disorders, such as stroke. The scoring system ranges from 0-14, with higher scores indicating better motor function. The FMA-UE-Hand Motor domain assessment system is broken down into several subscales, namely Mass Flexion and Extension movements, followed by functional movements of grasping (Grasp), including Hook Grasp, Thumb Adduction, Pincer Grasp, Cylinder Grasp, and Spherical Grasp. The assessment will get a score of 0 = None or no movement, 1 = Partial or limited movement, and 2 = Full or perfect movement. 2. The NHPT assessment consists of a square board with 9 pegs. At one end of the board, there is a hole for the peg, and at the other end, there is a shallow round plate for holding the peg. NHPT is performed by having the patient take pegs from a container, one at a time, and place them into the holes in a board, as quickly as possible. The patient must then remove the pegs from the holes, one at a time, and reinsert them into the housing. To practice and register initial scores, the test must be started with the unaffected upper limb. The board should be placed in the centre of the patient's body with the housing holding the pegs oriented toward the hand being tested. Only the hand being evaluated should perform the test. The non-evaluated hand is allowed to grip the edge of the board to provide stability. Patients are scored based on the time required to complete the test activity, recorded in seconds. The stopwatch must start from the moment the participant touches the first peg until the last peg touches the container. This assessment requires a board, of wood or plastic, with 9 holes (10 mm diameter, 15 mm depth), spaced 32 mm or 50 mm apart and a stopwatch. 3. Tenascin-C To perform an ELISA for Tenascin-C, the procedure involves preparing samples and standards according to the kit instructions. The samples and standards are added to wells pre-coated with Tenascin-C-specific antibodies and incubated to facilitate binding. Following incubation, the wells are washed to remove any unbound substances. A detection antibody, conjugated with an enzyme, is then added and incubated. After additional washing, a substrate solution is introduced, causing a color change proportional to the amount of Tenascin-C present. The reaction is stopped with an acid solution, and the optical density is measured using a plate reader. The Tenascin-C concentration in the samples is determined by comparing the optical density readings to a standard curve. Typically, Tenascin-C levels are reported in pg/mL, and the assay range and sensitivity depend on the specific kit used. Accurate interpretation requires comparing the sample values to the standard curve to assess Tenascin-C expression levels, which can provide insights into the biological or pathological state being investigated.

9\. Sample Size

This clinical trial aims to compare the effectiveness of Robotic Therapy, Exergame Therapy, and Standard Therapy in improving hand function among post-stroke patients. Assuming a standard deviation of 26.75, an expected mean difference of 18.72, and a dropout rate of 30%, the sample size is calculated to be 16 participants per group. This calculation is based on a 95% confidence level (Zα = 1.96) and 80% power (Zβ = 0.84) across the three arms.

10\. Proposed Statistical Analysis

the data will be analyzed using Analysis of Variance/ ANOVA assuming no difference in baseline characteristic. Next, the relationship between continuous values will be assessed using the Pearson correlation test (normally distributed data) or the Spearman test (data not normally distributed) to determine how big the correlation is between these variables.
