Effects of Transcranial Direct Current Stimulation After Short-term Immobilization on Motor Learning and Hand Function in Healthy Young Adults
- Conditions
- Transcranial Direct Current Stimulation
- Registration Number
- NCT07089056
- Lead Sponsor
- Beijing Sport University
- Brief Summary
The purpose of the study is to investigate the effects of short-term braking on the motor learning and fine motor skills of healthy adults, and to analyze whether transcranial direct current stimulation can alleviate the effects of braking on motor learning and fine motor skills.
- Detailed Description
The purpose of the study is to investigate the effects of 16-hour short-term immobilization on the motor learning and fine motor skills of healthy adults, and to analyze whether transcranial direct current stimulation intervention can alleviate the effects of immobilization on motor learning and fine motor skills.

- Primary Outcome Measures
Name Time Method Sequence Reaction Time Task Baseline; after one week The participants will sit in front of the laptop and placed their four right fingers on the four keys on the keyboard. In this task, a white circle appears above one of four horizontally arranged white squares on the computer screen with black background. Participans will be instructed to press the proper button on the response pad (buttons H, J, K, L) using the corresponding finger of the right hand (index finger for button H, middle finger for button J, ring finger for button K, and small finger for button L) when the white circle appeared at the left side, middle-left side, middle-right side, or right side of the computer screen, respectively. Each session consists of eight blocks, with each block comprising 120 trials.
- Secondary Outcome Measures
Name Time Method Purdue Pegboard Test Baseline; after one week The Purdue Pegboard (model 32020; Lafayette Instrument Co., Lafayette,Indiana) performed the tests. The nail jacks were arranged in two parallel columns, and the nail, washer, and collar were placed in the four cups at the top of the plate before the experiment began. Subjects will be prompted to begin the test by using a nail to jack first with their right hand, then with their left hand, and finally with both hands simultaneously. Each segment was 30 s in duration, and the number of nails transferred by the participant was recorded. Finally, participants will assemble a nail, a washer, a collar and a washer on top of it, starting with their right hand in 1 minute. Each of the above sections was repeated three times to obtain an average score.
Reach and grasp action test Baseline; after one week The reach and grasp test included two parts: the fine grasp test and the gross grasp test. In the fine grip test, participants will be instructed to grasp a pencil with the tips of their thumb and index finger, and in the coarse grip test, they are instructed to grasp a tennis ball with their entire hand. Participants will seat in front of a table, and the tester placed the objects on the marked points. Participants began and ended the grasp task at the same location (30cm from the marker), and all performed the same posture (index finger in contact with thumb). Participants will complete the grasp task 15 times at their own pace.
Infrared motion capture system will be used to record 3D kinematic data during the reaching and grasping movements.
