| Summary: | 碩士 === 國立成功大學 === 生物醫學工程學系 === 105 === The performance of hand such as digit force control and digit independence was influenced due to impaired sensation, insufficient strength, and abnormal synergy pattern on patients after stroke. Previous studies showed lower digit independence and lower strength on affected hand of stroke compared to the control group. However, these literatures didn’t study the training effects on digit force control and digit independence for patients after stroke. The relationship among digit force control, digit independence, and hand function was still unclear.
In current study, RMSD and k value calculated from FFT of PETS represented digit force control and digit independence respectively. Multi-digit training with PETS was an intervention for all subjects in the experiment. Twenty seven health controls and ten patients after stroke were recruited to study the relationship among digit force control, digit independence, and hand function. The data of seven patients and seven age-matched controls were analyzed to reveal training effects.
The resulted showed digit force control had a significant positive relationship (p-value 〈 .01) with grasp force and hand function. Patients after stroke showed the poor performance of digit force control, digit independence, digit sensation, and hand function than controls. Besides, grasp force of stroke was smaller than controls as well. In the training effects, patients after stroke showed improvement on RMSD, 2-PD, grasp force, B＆BT, and ARAT. k value in stroke increased in some combinations of multi-digit. To sum up, multi-digit training with PETS might improve digit force control and digit independence on patients after stroke.
The small sample size of stroke was the limitation in current study. The insufficient number of stroke and high variation within patients might cause no significant change on effects after multi-digit training.
