Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change From Baseline in Fugl-Meyer Assessment for Upper Extremity (FMA-UE) Score | Baseline and 1 month | Change in upper limb motor function measured using the Fugl-Meyer Assessment for Upper Extremity (FMA-UE). The total score ranges from 0 to 66, with higher scores indicating better upper limb motor function. Change is calculated as the score at 1 month after electrode removal minus the baseline score. |
| Secondary | Change in Action Research Arm Test Score | Week 4 of stimulation (electrode removal) and 1 month after electrode removal | Upper limb functional performance will be evaluated using the Action Research Arm Test (ARAT), which assesses grasp, grip, pinch, and gross arm movements. The total score ranges from 0 to 57, with higher scores indicating better upper limb function. Change will be calculated as the score at 1 month after electrode removal minus the score at Week 4 of stimulation. |
| Secondary | Change in Brunnstrom Recovery Stage of the Upper Extremity | Week 4 of stimulation (electrode removal) and 1 month after electrode removal | Motor recovery of the affected upper extremity will be assessed using the Brunnstrom Recovery Stages. Recovery is classified into six stages, ranging from Stage I (flaccidity without voluntary movement) to Stage VI (near-normal voluntary movement and coordination). Higher stages indicate better motor recovery. Change will be calculated as the stage at 1 month after electrode removal minus the stage at Week 4 of stimulation. |
| Secondary | Change in Nine-Hole Peg Test Completion Time | Week 4 of stimulation (electrode removal), 1 month and 2 months after electrode removal | Fine motor dexterity of the affected hand will be assessed using the Nine-Hole Peg Test (NHPT). The time required to place and remove nine pegs will be recorded in seconds. Shorter completion times indicate better fine motor performance. Change will be calculated as the completion time at each follow-up assessment minus the completion time at electrode removal. |
| Secondary | Change in Grip Strength of the Affected Hand | Week 4 of stimulation (electrode removal), 1 month and 2 months after electrode removal | Grip strength of the affected hand will be measured using a hand dynamometer and recorded in kilograms (kg). Higher values indicate greater grip strength. Change will be calculated as the grip strength at each follow-up assessment minus the grip strength at electrode removal. |
| Secondary | Change in Lateral Pinch Strength of the Affected Hand | Week 4 of stimulation (electrode removal), 1 month and 2 months after electrode removal | Lateral pinch strength of the affected hand will be measured using a pinch gauge and recorded in kilograms (kg). Lateral pinch strength represents the force generated between the thumb and the lateral aspect of the index finger. Higher values indicate greater pinch strength. Change will be calculated as the value at each follow-up assessment minus the value at electrode removal. |
