“…Kang et al 11 ) asserted that repetitive therapeutic ultrasound work of low intensity for a short period may increase the work load on the spinal erectors, depending on the height of the treatment table. In addition, Lee et al 12 ) stated that the muscle activity of shoulder muscles is affected by table height and that extensive use of the shoulder muscle causes muscle fatigue, which in turn can cause musculoskeletal pain. Accordingly, this study examined the effect of treatment table height during ultrasound work on shoulder muscle fatigue, and based on the results, we present an appropriate working environment, potentially contributing to the prevention of musculoskeletal pain of physical therapists.…”

[Purpose] The purpose of this study was to propose a table height that can reduce shoulder muscle fatigue by analyzing and comparing median frequencies of shoulder muscles at different table heights when performing therapeutic ultrasounds work. [Subjects and Methods] The subjects were 63 healthy male adults who were equally and randomly assigned to a standard height group (SHG), a high height group (HHG), and a low height group (LHG). The standard table height was set at the level of the elbow joint when the subjects flexed their elbow while in a sitting position. High height and low height were set 10 cm higher and 10 cm lower, respectively, than the standard height. Muscle fatigue of the upper trapezius, middle deltoid, rhomboid, and infraspinatus of the subjects was measured during ultrasound treatment work at each table height. [Results] Median frequencies of the upper trapezius, middle deltoid, rhomboid, and infraspinatus muscles were significantly lower in the HHG than in to the LHG. [Conclusion] When therapeutic ultrasound is performed using a table that has a height lower than that of the elbow joint, the median frequency of the shoulder muscle increases, hence decreasing muscle fatigue. This way, musculoskeletal pain as a result of performing therapeutic ultrasound can be prevented.
