[Purpose] The purpose of this study was to investigate whether transcutaneous electrical nerve stimulation simultaneously combined with local heat and cold applications enhances pain relief compared with transcutaneous electrical nerve stimulation alone in patients with knee osteoarthritis. [Subjects and Methods] Fourty-five patients with knee osteoarthritis participated in this study. They were randomly assigned to the following three interventions: transcutaneous electrical nerve stimulation simultaneously combined with local heat using a hot pack; combined with local cold using a cold pack; and transcutaneous electrical nerve stimulation alone. In each intervention, the knee pain level during walking and standing up from a chair, as well as dynamic balance and gait ability were evaluated immediately before and after a single intervention using the visual analogue scale and the timed up & go test, respectively. [Results] A significant improvement in dynamic balance and gait ability was only observed immediately after transcutaneous electrical nerve stimulation simultaneously combined with local heat application, although the degree of pain relief during standing and walking were comparable among the three interventions. [Conclusion] These results suggest that transcutaneous electrical nerve stimulation simultaneously combined with local heat application can immediately improve not only knee pain during standing and walking but also dynamic balance and gait ability in patients with knee osteoarthritis.

[Purpose] The purpose of this study was to investigate the effect of the difference in attentional focus, including the external focus (EF) or internal focus (IF) during exercise on attention resources from the viewpoint of the brain activity. [Participants and Methods] The study included 20 healthy adult participants randomly assigned to two groups: the EF and IF groups. The participants in each group received different verbal instructions before performing a tennis ball task, in which they threw a tennis ball on the floor at a target with their non-dominant hands as accurately as possible while sitting on a chair. During the task, oxygenated hemoglobin (oxy-Hb) in the right dorsolateral prefrontal cortex was continuously measured using a near-infrared spectroscopy device. The accuracy of the task and the change of oxy-Hb were statistically analyzed. [Results] Although there were no statistically significant differences between the groups, both accuracy of the task and oxy-Hb in the EF group were found to be higher than those in the IF group. [Conclusion] Our results showed that although the accuracy of motor control in the EF was superior to that in the IF, there is a possibility of increased attention resources in the EF compared to those in the IF.
