目的:立位での一側下肢への側方体重移動における腰背筋群・足部周囲筋の役割を解明する目的で,側方移動中の姿勢変化と腰背筋群・足部周囲筋の筋活動パターンを検討した.方法:対象は健常男性24名(24.3±2.6歳).直立位から2秒間で側方移動させ,そのときの足底圧中心(COP)と両側多裂筋・腸肋筋・最長筋,移動側足部内反筋群・腓骨筋群の筋電図波形,ビデオ画像を計測した.結果:骨盤は水平移動した後,COPの移動側変位途中から非移動側挙上を生じた.下肢では側方移動に伴い移動側足部回内による下腿の外側傾斜を生じた.このとき,COPが移動側へ変位する途中から非移動側多裂筋・腸肋筋・最長筋,移動側足部内反筋群・腓骨筋群の筋活動が増加した.結論:非移動側多裂筋・腸肋筋・最長筋は骨盤非移動側挙上に対する胸腰部非移動側側屈に関与した.このとき,足部内反筋群・腓骨筋群は足底接地した状態での足部回内に関与した.

In this study, we examined the patterns of activity of the trunk muscles during weight shifting to one side of the lower limbs in the standing position in five patients with Parkinson’s disease and trunk malalignment. In the movement task, the patients first shifted their weight to one side of the lower limbs and attempted to move the maximum distance in which they could shift their weight to the moving limb in 1 s. Then, the patients held the posture with the maximum weight shift for 1 s and returned to the starting position in the next 1 s. The patterns of activity of the bilateral multifidus, iliocostalis, and longissimus muscles as well as that of the internal oblique and gluteus medius muscles on the weight-bearing side were analyzed. Compared with that of the starting position, we observed an increase in thoracic kyphosis during the movement task, and this was common to all of the patients. In addition, although we observed coronal plane inclination of the pelvis associated with hip joint movement during the movement task, 4 of the 5 patients did not show any change in trunk alignment compared with that in the starting position. The patterns of activation had the following characteristic tendencies: activation of the bilateral longissimus muscles was observed in the starting position in all patients, activation of the longissimus and iliocostalis muscles on the nonweight-bearing side was increased in 4 of the 5 patients, and activation was weak in the internal oblique and gluteus medius muscles on the weight-bearing side in 4 of the 5 patients. We observed a significant difference between the muscle activation patterns reported by previous studies of healthy subjects and those of our present study. When using weight shifting to one side of the lower limbs in the standing position as an exercise therapy for patients with Parkinson’s disease, activation of the internal oblique, gluteus medius, and multifidus muscles on the weight-bearing side increases. Therefore, it is necessary to implement exercises with the intention of performing the movements, with the pelvis in a horizontal position and the trunk in a vertical position. Moreover, it is necessary to ensure that activation of the bilateral longissimus muscles or that of the iliocostal muscle on the nonweight-bearing side does not differ from the activation of the starting position.

To investigate the effects on postural change and muscle activity in foot muscles during lateral weight shift while wearing an AFO. The subjects were 15 healthy men (average age 24.9 ± 2.5 years old). They performed a lateral weight shift in the standing position to the right lower limb while wearing an AFO on the right foot, then repeated the process without one. In each instance, postural change and electromyograms (EMG) of the peroneus, foot supinator muscles, and tibialis anterior were measured. When initiating the lateral weight shift while wearing the AFO, hip adduction on the moving side resulted in pelvic depression on the non-moving side. Continuation of the lateral weight shift also resulted in lateral flexion of the thoracolumbar area on the moving side, as well as outward inclination of the lower limb on the moving side. Compared to the barefoot lateral weight shift, there was a trend toward overall decrease in muscle activity in the peroneus, foot supinator muscles, and tibialis anterior. During a lateral weight shift while wearing an AFO, the AFO limits both foot pronation and supination. It can be surmised that this function of the AFO results in reduced muscle activity of the peroneus, used for grounding the foot, as well as in reduced muscle activity of the foot supinator muscles and tibialis anterior, which are used to restrict outward inclination of the lower limbs.

In this study, we examined the relationship between the activity pattern of hamstring muscles and postural change of weight shift, in the standing position. We used surface electromyographic data from the medial gluteus medius, biceps femoris, and semitendinosus muscles of 10 healthy male participants. During exercise tasks, we observed two groups of participants: those who registered ankle dorsiflexion during lateral weight shift movements and those who did not. The former group registered an increase in hamstring muscle activity and the latter group registered no change. Similar to a previous study, an increase in gluteus medius muscle activity was detected along with the start of lateral weight shift. It appears that the biceps femoris muscle works to increase hip extension before semitendinosus muscle activity, causing a forward weight shift and dorsiflexion of the ankle joint during lateral weight shift in the standing position.

The purpose of this study is to investigate the main factors of the air temperature distribution in basin city in summer. Hadano is a basin city located in Kanagawa. At first, authors measured the air temperature of 14 points in Hadano during the summer (July 13 - August 31) in 2011. As a result, the spatial distribution patterns of the maximum and minimum temperature are different from each other. In the analyses, authors picked green coverage, ventilation condition, amount of solar radiation and elevation, as main factors of forming air temperature distributions. As a result, daytime temperature is influenced by the ventilation and nighttime temperature is strongly influenced by green cover.
