RESUMEN

(1) Background: The objective of this study was to recognize tai chi movements using inertial measurement units (IMUs) and temporal convolutional neural networks (TCNs) and to provide precise interventions for elderly people. (2) Methods: This study consisted of two parts: firstly, 70 skilled tai chi practitioners were used for movement recognition; secondly, 60 elderly males were used for an intervention study. IMU data were collected from skilled tai chi practitioners performing Bafa Wubu, and TCN models were constructed and trained to classify these movements. Elderly participants were divided into a precision intervention group and a standard intervention group, with the former receiving weekly real-time IMU feedback. Outcomes measured included balance, grip strength, quality of life, and depression. (3) Results: The TCN model demonstrated high accuracy in identifying tai chi movements, with percentages ranging from 82.6% to 94.4%. After eight weeks of intervention, both groups showed significant improvements in grip strength, quality of life, and depression. However, only the precision intervention group showed a significant increase in balance and higher post-intervention scores compared to the standard intervention group. (4) Conclusions: This study successfully employed IMU and TCN to identify Tai Chi movements and provide targeted feedback to older participants. Real-time IMU feedback can enhance health outcome indicators in elderly males.

RESUMEN

@#Objective To evaluated the effect of special nursing after coronary intervention in elderly.Methods 142 cases of consecutive patients with coronary artery disease were treated with percutaneous coronary intervention.According to the nursing models,the patients were divided into special nursing group(86 case) and routine nursing group(56 case).Results The incidence of aypnia,dysphoria,hospital onset of infection or other complication after intervention in special nursing group was less than that of routine nursing group.Conclusion The special nursing may accelerate the recovery of the old patients with coronary artery disease after coronary intervention.
