Background: It is common for elderly to have worries or anxiety issue while there were few studies addressed the effectiveness of current occupational therapy relaxation intervention in visual impaired older adults. Apart from relaxation technique such as pursed lip breathing and progressive muscle relaxation, Chinese traditional mind-body intervention may have an advantage in adopting by Chinese older adults due to cultural reason.
Objective: To investigate the treatment effectiveness of relaxation training(RT) and traditional mind-body intervention(MBI) in community occupational therapy service.
Methods: 10 clients in Kowloon Home for the Aged Blind were divided into four groups to receive 20 sessions of relaxation training: pursed lip breathing, progressive muscle relaxation, Baduanjin, and Dejian Mind-body intervention. GDS-15, GAD-7, MMSE, PSQI, daily participation in rehab activity and sleep data were collected before the study. the score of GSD-15, GAD-7 and PSQI were collected after all interventions completed. The effectiveness of each relaxation technique was monitored by EEG feedback through wearable brain device. EEG was recorded from Frontal(F3/F4/F7/F8/AF3/AF4), Temporal(T7/T8), Central(FC5/FC6), Parietal(P7/P8) and Occipital(O1/O2) regions of the 10-20 system. For the 5-min BEGIN and 5-min END period, the epochs were subjected to the fast Fourier transformation (FFT) and mean amplitude of Alpha and Theta frequency component for each 14 channel were averaged to derive the grand mean for the five independent cortical regions. The change of mean peak amplitude of Theta brainwave in Channel O1 throughout sessions for each relaxation intervention were plotted as well. Blood pressure, heart rate and SpO2 were collected before and after each session of intervention.
Results: There were no significant change of blood pressure and heart rate in traditional relaxation method. However, there were an overall change in Theta brainwave for both Baduanjin and Dejian Mind-body intervention when compared the begin and end of sessions in Occipital region.
Conclusion: Both Baduanjin and DMBI demonstrated certain effectiveness in relaxation intervention for visual impaired older adult. It was suggested to conduct a large scale study to further investigate
