The study is to evaluate the effect of 3D printing functional splints on hand function for patients with stroke.Twenty stroke patients with moderate motor deficits were recruited and randomized into experimental (3D printing splint) or control (functional splint) groups for 8 weeks of treatment.The performance was assessed by a blinded assessor for two times including motor, function, and feasibility.Collected data will be analyzed with nonparametric tests by SPSS version 20.0, and alpha level was set at .05.
Background: Spasticity is an important factor limiting independency and activity of daily living for post-stroke patients. Splinting has been proved to be successful treatment for spasticity.3D printing technology was used to construct personalized, complicated orthosis, and one piece to reduce assembly time. The evidence most are product development, but few of study investigate the effectiveness.
Aim: To evaluate the effect of 3D printing functional splints on hand function for patients with stroke.
Methods: Twenty stroke patients with moderate motor deficits were recruited and randomized into experimental (3D printing splint) or control (functional splint) groups for 8 weeks of treatment (Sixty minutes for position and twenty minutes for training a time, triple times a day). The performance was assessed by a blinded assessor for two times included Fugl-Meyer Assessment-Upper Limb section(FMA-UE), Electromyography (EMG), Grip dynamometer, Passive Range of motion (PROM) at upper extremity, Muscle tone at upper extremity, and Disability of the arm, shoulder and hand questionnaire(DASH). The splint wearing performance and Satisfaction were recorded. Collected data will be analyzed with nonparametric tests by SPSS version 20.0, and alpha level was set at .05.

The grip dynamometer was used to measure the maximum isometric strength of the hand and forearm muscles. The mean score of 3 trials was calculated. For this measurement, the elbow was placed at 90° and the forearm was placed in mid-position.The unit of measure is kilograms.
| Change from Baseline at 8 weeks |
| Range of motion of upper limb joints | Passive movement angle of elbow joint, wrist joint and thumb, finger metacarpophalangeal joint.The unit of measure is degree. | Change from Baseline at 8 weeks |
| Disabilities of The Arm, Shoulder And Hand Questionnaire | a self-administered region-specific outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The DASH consists mainly of a 30-item disability/symptom scale, scored 0 (no disability) to 100. We used the subtest of Activity capacity, severity of illness.The unit of measure is score. | Change from Baseline at 8 weeks |
| Side effects record | The number of side effects after intervention (such as soreness, pain, motion vertigo, injury, etc.) were recorded every day. The unit of measure is number of times. | Every training session, total sessions continued to 8 weeks |
| Satisfaction questionnaire | The questionnaire is a subjective self-filling scale using a hand brace, with 5-level scores (strongly agree to strongly disagree), including aesthetics, complexity, weight, resistance, comfort, ease of wear, etc.The unit of measure is score. | Every training session, total sessions continued to 8 weeks |
