“… 30 ) described the interaction between the active tissues and passive tissues of the lumbar muscles by showing that in the 81° forward-stooping posture, the myoelectric potential of the erector spinae and multifidus muscles was lowered while the passive tissue moments of the lumbar region increased in comparison with shallower forward-stopping postures. Furthermore, the activity of the erector spinae muscle in the myoelectric potential linked with an excessive forward-stooping posture decreased or did not differ in comparison with shallower forward-stooping postures, whereas the myoelectric potential of the biceps femoris muscle was elevated 16 , 30 ) . In other words, the mean anterior inclination angle was 81° in this study during the ROM task at LH, the excessive forward-stooping posture at LH may have led to a flexion-relaxation phenomenon and reduced active tissue activity of the erector spinae muscles, while raising the activity of the muscle of the posterior surface of the thigh in return.…”

“…The height of mat platforms at hospitals and welfare facilities is also usually 45 cm. Previous studies in Japan have investigated the effects of bed heights and the presence or absence of a sheet in connection with the task of correcting the lying in a dorsal position at 47 cm (low) and at 85 cm (high) 16 ) . However, overseas studies regarding bed heights and working heights for manual patient handling tasks do not include any studies on the physical burden resulting from low beds of 45 cm or so.…”

Effects of different bed heights on the physical burden of physiotherapists during manual therapy: an experimental study

This study aimed to determine the effect of physiotherapists’ physical burden caused by different bed heights during manual therapy. Thirty-three male physiotherapists performed tasks simulating lumbar massage and passive hip abduction range-of-motion exercise (ROM) on the beds with low height (LH) and adjusted height (AH), with each task performed three times. The anterior inclination angle of the physiotherapist’s trunk was measured, the surface electromyograms of the erector spinae and trapezius muscles were recorded, and perceived stress was assessed. The indexes obtained were statistically compared for different bed heights. Additionally, the lumbar disc compression force and flexion torque were estimated. The lumbar burden caused by the excessive bending and the biomechanical burden and perceived stress were stronger at LH than AH. In ROM tasks using the right hand, the muscle activity was lower at the left lumbar region at LH than at AH. At LH, the anterior inclination angle increased and the lumbar muscle activity declined as the number of tasks increased. The burden on the shoulders was not significantly different by bed heights. Our results showed that, when physiotherapists perform manual therapy, it is necessary to adjust the bed height to reduce physical burden and ensure higher quality of service.
