[Purpose] The purpose of this study was to examine changes in the carpal tunnels and median nerves appearing due to frequent movements of fingers by ultrasonography in young adults who frequently use smartphones. [Subjects] The subjects of this study were 20 young male and female adults who had no limitation in the range of movement of neck, shoulder, and arm joints, musculoskeletal disorder of the arm, or neurological symptoms such as paraesthesia and agreed to participate in the study. [Methods] The subjects who agreed to participate in this study were asked to use a smartphone for 30 minutes while maintaining comfortable sitting postures on a chair. They were asked to maintain the position of their shoulders comfortably while maintaining an angle of around 90° at the elbow. Some values measured before and after the experiment using a smartphone for 30 minutes were compared. The carpal tunnel was measured using ultrasonography. [Results] There were significant differences in median nerve circumference length, area of the median nerve area, distance between the highest point of the median nerve to the lunate, and distance between the bottom point of the median nerve to the lunate between before and after the experiment(p

[Purpose] The purpose of this study was to examine the degree of changes in gait and feet after wet heat and dry heat exposure for 20 minutes. [Subjects] The participants of this study were 17 young adult males. The subjects were divided into a wet heat group of 9 subjects and dry heat group of 8 subjects. [Methods] Dry heat was applied for 20 min. To facilitate temperature adjustment of an electrical hot pack, to which a temperature controller was attached to the hot compress, the outer cover of the electrical pad was wrapped in a cotton towel and then rolled around the femur and the leg. As a hot compress, a constant-temperature water tank with double-boiling functionality was used for the hot pack unit. Its surface was covered with a towel twice or three times, as needed. We measured gait and feet. [Results] Left and right step time and the step width significantly increased in the wet heat group. Left foot flat to heel off significantly increased in the dry heat group. Right heel contact to foot flat significantly increased in the wet heat group. Left rearfoot pressure significantly increased in the dry heat group. [Conclusion] Wet heat affects physical functions like gait more than dry heat. However, there is no great difference between wet heat and dry heat with respect to the distribution of foot pressure.

[Purpose] The purpose of this study was to evaluate the effect of modified cervical exercise and determine whether such exercise improves the range of motion of the cervical movement in smartphone users with forward head posture. [Subjects and Methods] Some 32 subjects with forward head posture participated in this study. They were randomly allocated to three groups, and the modified cervical exercises were performed either once, twice, or three times per day. The exercise program was followed for four weeks and then the joint range of motion of the participants was measured. [Results] A significantly increased range of motion was seen in all three groups that performed the modified cervical exercises. The analysis of the effects among the three groups indicated that the greatest effect was seen in Group C, members of which performed the modified exercises three times per day. In addition, a significant difference was found between Group A and Group C in terms of the inter-group results. [Conclusion] According to the results of this study, although the modified cervical exercises were performed for only a relatively short duration (four weeks), the exercises brought about an improvement in the forward head posture that was induced by using a smartphone.

[Purpose] The purpose of the present study was to verify a new method for improving respiratory functions by applying both abdominal stimulation and inspiratory muscle training (IMT) to train the inspiratory muscle and the expiratory muscle simultaneously, to improve the efficiency of IMT of chronic stroke patients. [Subjects] Eighteen stroke patients were randomly assigned to an experimental group (n = 9) and a control group (n = 9). [Methods] The experimental group was administered IMT with abdominal stimulation, and the control group was administered only IMT. During the intervention period, the experimental group and control group received training 20 min/day, 3 times/wk, for 4 weeks. To examine the lung functions of the subjects, FVC, FEV1, PEF, and FEF25–75 were measured using an electronic spirometer. The diaphragm thickness ratio was calculated from measurements made with a 7.5-MHz linear probe ultrasonic imaging system. [Result] The experimental group and the control group showed significant increases in diaphragm thickness ratio on the paretic side, but not on the non-paretic side. With regard to lung function, the experimental group showed significant increases in FEV1, PEF, and FEF25–75. The changes between before and after the intervention in the two groups were compared with each other, and the results showed significant differences in FEV1 and PEF. [Conclusion] The present study identified that IMT accompanied by abdominal stimulation improved the pulmonary function of chronic stroke patients.

[Purpose] The purpose of this study was to examine the degrees of changes in the gait and feet when walking on a treadmill using Nordic poles and without Nordic poles for 30 minutes. [Subjects] The participants of this study were 30 young adult males. The subjects were divided into a Nordic pole walking group of 15 subjects and a normal walking group of 15 subjects. [Methods] The subjects in both groups were encouraged to face forward and walk in comfortable postures on the treadmill. They did not wear any shoes during walking, and the speed of the treadmill was set to the average of the speeds at which the subjects could comfortably walk in both groups. We measured the gait and feet. [Results] In the Nordic pole group, step length was significantly increased. The rate of each segment from heel contact to foot flat and foot flat to heel off during the stance phase after gait showed significant differences between before and after the experiment. [Conclusion] The results of this study indicate that Nordic pole walking increases the stride and can be considered as helping patients with a disease affecting their gait. Since the use of Nordic poles shortens the time from foot flat to heel off, it is considered that the use of Nordic poles can shorten the midstance during the stance phase.
