These students usually had complaints of stiffness of shoulder and/or lumber. Back massages significantly reduced the level of serum cortisol from 8.85 ± 0.78 to 5.95 ± 0.68 μg/dl, without affecting that of lactate. The treatment also improved the stiffness of the trapezius of students with complaints from 63.24 ± 0.78 to 59.12 ± 0.78 after the treatment without affecting skin blood flow (SKBF). In addition, back massages reduced the VAS value at the same time. These results indicate that back massages of the student are effective to improve the physical and psychological conditions of the students.展开更多

It was found that sleep postures and diurnal activity determines, to some extent, sleep parameters including activity mean score (AMS), activity index (ACTX), waking episodes (WEP) and sleep fragmentation index (SFX). It was also found that sleep properties are different in younger and senior Japanese. For example, increase in the proportion of time in the supine position resulted in enhancement and deterioration of the sleep in the younger and senior groups, respectively. Furthermore, there were correlations between supine posture and AMS, ACTX, SFX, total minutes scored as awake (TMSA) and WEP obtained by actigraphy in the younger group, but only AMS and ACTX in senior group. In addition, we also assessed sleep parameters by use of questionnaires, and found that objective sleep quality was rather poor but subjective sleep quality was better in the senior group. In the younger group, in contrast, objective sleep quality was better but subjective sleep quality was poor. On the other hand, there was no correlation between sleep parameters assessed by actigraphy and self-report at all. The present study with A-MES and actigraphy provides the first evidence that sleep posture affects sleep quality and is a convenient, inexpensive and home-based method for studying sleep.展开更多
