Integration Hand Training System With Mirror Visual Feedback For Hand Function and Brain Activation
- Conditions
- Healthy Elderly
- Registration Number
- NCT07077460
- Lead Sponsor
- National Cheng-Kung University Hospital
- Brief Summary
Previous studies showed that mirror therapy, compared with traditional rehabilitation treatments, can continuously provide cortical activation. Besides, several studies indicated that game-based interventions contribute to brain activation in the elderly due to their interest can improve users' motivation in the training program execution. In addition, force control training has positive effects on hand dexterity, and specific doses of motor control training not only improve motor function but also have positive effects on brain function. Currently, hand function training primarily focuses on range of motion, strength, and hand function, although there is comparatively less emphasis on enhancing both force control and brain function. However, there is lacking studies focusing on investigating the effects of the integration force control training into mirror therapy until now. In addition, there are no studies on the exploration of how the brain activation works in different task difficulties and the force level of hand training. Additionally, visual feedback from force control training in our study is through the hints displayed virtually on the game interface of the tablet, which were represented as the height of the targets, not as typical as actual movement-based mirror therapy or task-based mirror therapy. Therefore, the motivation of the study is to understand the effects of practicing force control training with Mirror Visual Feedback (MVF), and explore the brain activity during different task complexity and force levels. So, the purpose of the study is to understand the training effects of integrating MVF and with force control training, and to explore the brain activation in different task difficulties and force levels.

- Primary Outcome Measures
Name Time Method Hand Strength 15 minutes Handgrip strength and pinch strength was measured respectively. JAMAR Grip Hand Dynamometer and JAMAR Hydraulic Pinch Gauge were used for the apparatus for force measurement. Pinch strength was divided into lateral pinch, tip pinch and tripod pinch.
Purdue Pegboard Test (PPT) 10 minutes Assess the manual dexterity and coordination for one and both hands, including one hand, two hand and assembly subtest. ( Test for dominant hand and non-dominant hand). Each subtest test for three times.
Oxygenated hemoglobin (HbO) 40 minutes The Oxygenated hemoglobin (HbO) was measured while the participants play the game under both conditions
Minnesota Manual Dexterity Test (MMDT) 25 minutes Assess the eye-hand coordination ability and manual dexterity. MMDT was divided into: Turning, Placing, One hand Turning and Placing, Two hand Turning and Placing, Displacing.
Digit Independence (EN value) 40 seconds for each digits The force independence is collected from the data during force control game in each evaluation session. The parameter of force independence is an index of five digits overall enslaving presented as EN
- Secondary Outcome Measures
Name Time Method Maximum voluntary isometric contraction (MVIC) 1 seconds for each digit Maximum voluntary isometric contraction of each digit is measured for training reference
