This article describes the intervention for improvement of the limitation of range of ankle dorsal flexion. A limited range of ankle dorsal flexion is caused by shortening of antagonist musde or joint capsule, decrease of joint play and disorder of the axis of dorsal flexion. Especially, a disorder of the joint axis is the most important finding among all causes. Disorder of the joint axis has a close relation with shortening of the soft tissue around the ankle joint. Especially, there are some typical parts, in which shortening of the soft tissue is related to disorder of the ankle motion axis. These parts were identified as the D-point (Daikuya's normalizing point for ankle axis). Compression and stretching to the D-point normalized ankle axis disorder. Normalizing the ankle axis is an important strategy in physical therapy for the limitation of the range of ankle dorsal flexion, because normal soft tissue is loosened and shortened tissue is untouched in physical therapy for an abnormal ankle axis.

This article sets out the classification of stretching techniques as the basic physical therapy approach for the limitation of joint motion. To achieve adequate stretching for muscle shortening, it is necessary to evaluate joint instability, laxity and alignment, and muscle conditions, such as the limit to joint movement imposed by muscle contraction. And in this article, the concept of muscle stretching for lateral hamstring muscles and triceps surae muscles is introduced.

Limited range of motion in the knee joint is often observed in patients after total knee arthroplasty. Decreased extensibility of the skin is one of the factors limiting motion. The purpose of this study was to examine the extensibility of the skin over the knee during knee flexionat at angles of 0°, 30°, 60°, 90°, 120°, 150°, and maximal flexion as performed by 30 healthy subjects (15 males, 15 females). The skin covering the anterior area of the knee was divided into 4 sections: skin over the femur, the suprapatellar bursa, the patella, and the patellar ligament. The dimensions of each section at each flexion position were measured. The results indicate that the extensibility of the skin over the suprapatellar bursa and the patella in positions from 0° to 30° was significantly greater than that covering the femur and the patellar ligament (p<0.05). In addition, as the degree of knee flexion increased, the extensibility of the skin over the suprapatellar bursa and the patellar ligament was greater than that over the other areas. The results of this study indicate that evaluation of skin extensibility during physical therapy for patients with limited range of motion in the knee must include not only the area that shows limited motion but also the surrounding areas.

D test is an evaluation maneuver to hypothesize problems related to activities in daily life when a patient cannot perform because of some functional disorders. The procedure in the D test consists of three phases. In the first phase, the therapist investigates the joint motion axis during the ankle dorsal flexion of a patient. Next, the normal axis of ankle dorsal flexion is compared to the patient's actual axis. Finally, the therapist considers about factors and effects due to ankle axis abnormality, and observes and analyzes the ‘chain’ action from foot to head. The D test is very useful in the field of physical therapy evaluation. And for its clinical applications, it is necessary to master human functional anatomy and kinesiology.

A difference of alignment of rear foot between lying down and standing in patients who have sports disorders is often observed. The purpose of this study was to clarify the relationship between the alignment of the rear foot and activities of ankle flexor muscles during the calf-raise. We identified an alteration of the alignment of the rear foot between the prone position to standing by measuring leg heel angle under each condition, and classified subjects into three groups (varus, neutral, valgus) according to angle alteration. In addition, we measured activities of the tibialis posterior muscle, soleus muscle, medial head of the gastrocnemius muscle and lateral head of the gastrocnemius muscle during the calf-raise with surface electromyography. The varus group showed significantly greater activation of the tibialis posterior muscle than the valgus group. Activation of the medial head of the gastrocnemius muscle displayed similar findings with an increase from the valgus group to the neutral and varus groups. These results suggest that if alignment of the rear foot in standing is more varus than in lying prone, sports disorders are potentially more likely in therapeutic calf-raise exercises and in running during training.

The foot region plays an important role in postural control. It is often observed that improvement of foot and foot joint functions leads to improvement of movements of the lower limbs, pelvis, trunk, and eventually the entire body. We generally use the position of plantar pressure as a parameter for the evaluation of the foot region and foot joints, because the center of plantar pressure (COP) provides important information. In patients with dysfunction in the foot region, COP is often deviated to the big or little toe side during movements, or induction of COP from the little toe side to the big toe side is often difficult. In therapeutic exercise for control of COP in such patients, closed kinetic chain exercise is considered effective. In such exercises, monitoring of the necessary activities of the peripedal muscles caused by changes in COP is important. In this study, we examined the electromyographic integral of the peripedal muscles caused by changes in COP using a ground reaction force plate and electromyography. In the measurement, a surface electromyograph, Mlyosystem 1200 (NORAXON Co.), was used for recording electromyography. For electromyography analysis, MyoResearch (NORAXON Co.) software was used for calculation of the integrated values of the electromyography. A force plate (Anima Co.) was synchronized with the surface electromyograph. Weight loading on the forefoot and hind foot induced characteristic muscular activity patterns of muscles around the foot. For changing COP, muscular activity of muscles around the foot is necessary, and it is important to know that the muscular activity pattern varies depending on the position of COP.

The purpose of this study was to investigate whether ROM on pronation of the transverse tarsal joint affected both pelvic movement and EMG activity of gluteus medius muscle on hemi-standing. We researched two experiments about ROM limitation on pronation of the transverse tarsal joint. One was the inherent limitation: it was classified as the hypo-mobility side (ROM on pronation of the transverse tarsal joint <10°) or normal-mobility side (ROM on pronation of the transverse tarsal joint ≥10). Another was artificial limitation by meanes of taping. It discriminated between the non-taping group and the taping group (ROM on pronation of the transverse tarsal joint=0°). In each experiment, subjects were instructed to maintain hemi-standing with 90 degree hip flexion on the unsupported side. We compared the degree of eversion of the subtalar joint, pelvic movement and EMG activity of the gluteus medius muscle on the supported side on hemi-standing on both the hypo-mobility side and the normal-mobility side; and taping group and non-taping group in two experiments, respectively. In both of the two experiments on ROM limitation on pronation ofthe transverse tarsal joint, pelvic movement tended to increase pelvic elevating to the opposite side on hemi-standing or the degree of eversion of the subtalar joint on the supported side significantly increased on hemi-standing, and EMG activity of the gluteus medius muscle significantly increased on hemi-standing. We would like to emphasize that pelvic movement was altered by ROM limitation on pronation of the transverse tarsal joint. The main reason was that ROM limitation on pronation of the transverse tarsal joint on the supported side caused excessive eversion of the subtalar joint on hemi-standing. And excessive eversion of the subtalar joint caused the obstruction to shift the pelvis in the direction of the supported side for hemi-standing. We suggest that the pelvic elevation to the opposite side was caused to compensate for obstruction when shifting the pelvis in the direction of the supported side.

To clarify the function of the vastus medialis obliquus (VMO) and longus (VML), we investigated the electromyographic properties of superficial quadriceps femoris during fatiguing knee extension task.Ten healthy male and 10 female volunteers participated in this study. The subjects performed fatiguing knee extension task at maximal effort (10 times×10 set at 60 deg/sec). Surface electromyography (EMG) was recorded from the VMO, VML, vastus lateralis(VL) and rectus femoris(RF) during isometric knee extension (knee bent at 60 deg and 30% of the maximal voluntary contraction level) with a 90-sec interval between each set. Knee extension peak torque, integrated EMG (IEMG) and median power frequency (MDF) of four muscles during each set were compared using Dunnett's test.Knee extension peak torque decreased gradually and peak torque decreased significantly starting from set 9 in male subjects, while there was no significant decrease in female subjects. IEMG from VMO and VL increased linearly. IEMG increased significantly from set 7 in VMO and set 6 in VL for both male and female subjects. Then, IEMG from both VML and RF increased significantly starting from set 9 in VML and set 8 in RF in male subjects, while there was no significant change in female subjects.MDF of VMO, VL and RF also increased significantly at timepoints similar to those showing increases in IEMG in male subjects. However, MDF of VML increased significantly from set 4 in male subjects. On the other hand, MDF did not change significantly in female subjects.As a result of this study, it was suggested that VMO and VL were facilitated to maintain target knee extension torque during fatigue. Therefore, it was considered that VML and RF facilitated the maintenance of target torque under fatiguing conditions.

Foot function deteriorates after varus sprain of the ankle joint, and impairs smooth body movement in some cases. Dysfunction of the peroneal muscles, such as muscle weakness and delayed reaction time, occurs after varus sprain, and great importance has been attached to strengthening of the peroneal muscles in exercise therapy. Our exercise therapy targets stable posture control in weight-bearing on the little toe side, and we consider that not only the peroneal muscles but also varus muscles of the foot are important with regard to muscle activity in this position. In this study, we investigated muscle activity of the varus muscles of the foot and plantar pressure distribution on the supporting side in inward step positions as an exercise menu. Compared to the baseline position regarded as 0 cm, muscle activity increased at an inward step distance of 10 and 20 cm, and significantly increased at 30 and 40 cm (p<0.01). It is suggested that the inward steps induced weight-bearing on the little toe side, and forced tilting of the lower leg outward, during which the varus muscles may have acted to brake the outward tilting of the lower leg. This suggests that the varus muscles of the foot are important for posture control in weight-bearing on the little toe side.

We studied the relationship between the stand-up test using standing steps of different heights and isokinetic muscle strength of knee extension. In the stand-up test, whether or not a subject could stand-up on both legs or one leg from steps of different heights was assessed. As a result, the peak torque/body weight ratio was significantly greater in subjects who could stand on one leg than those who could not (p<0.05). In the subjects who could stand on one leg, the angle of peak torque (p<0.01) and total work (p<0.05) were significantly greater when using a step of lower height. It was revealed that while quantitative muscle strength (peak torque/body weight ratio) could be roughly evaluated by determining whether the subject could stand on one leg, the height of the step used in the stand-up test did not contribute to detailed evaluation of knee extensor muscle strength. However, using a step of lower height, it was found that the knee extensor muscle could function from the large flexion of the knee joint, thus making it possible to evaluate the qualitative muscle strength (angle of peak torque).

We had a patient with a tear of rectus femoris during running. As a characteristic finding, a big hematoma was identified by ultrasonography. The patient wanted to return to sports activities as soon as possible, because she was a competitor in an important game in a pennant race. So, we selected acupuncture therapy for improvement of hematoma. Especially, we chose electro-acupuncture, which is thought to be effective for early healing. As a result of electro-acupuncture therapy for three weeks, the hematoma was decreased however muscle activity had declined as measured by surface electromyography. Therefore we gave intermittent continuous wave pulse stimulation of 30 Hz to the rectus femoris. After the stimulation, muscle contraction was improved. The patient had no physical findings and returned to sports activities.

Observational motion analysis is an important method for evaluating impairments of patients after bone and joint surgery. For adequate motion analysis it is necessary to understand the following: relationship between impairments and mechanical stress to bone and joint; that nature of mechanical stresses does occur; the relationship between mechanical stress and alignment of extremities; and the basic information of individual diagnosis. In this study, taking into consideration the requirements noted above we investigated the construct of observational motion analysis for patients with bone and joint surgery. Within this construct, in addition to mechanical stress, alignment and basic information, it is thought that timing of joint motion, neurological mechanism of motion and locomotion of center of gravity are important, too, and also need to be well understood. Patients with bone and joint surgery have many types of impairment. So physical therapists have to perform not only routine tests and measurements but also adequate motion analysis if they are to improvement of patients' function.

The purpose of this study was to investigate the effect of differences of the foot center of pressure in standing on postural control of stand-to sit movement. It was thought that the reverse reaction phenomenon of standing posture in normal subjects at the fist of the sitting movement start by reduction of the muscle activity of the lumbar back muscles. Stable stand-to-sit movement was able to be performed when COP was located forward. From this, the position of foot COP in standing before stand-to-sit movement influences the difficulty of adjustment of COP and COG. Therefore, we suggest that in order to improve stand-to-sit movement, it is important to evaluate foot COP in the standing posture and muscle activity of the lumbar back muscles.

【はじめに】 運動プログラムを立案する際に筋力増強訓練と有酸素運動を組み合わせることが多い。先行研究では血液検査を用い、筋力増強訓練後に有酸素運動を実施した方が筋力強化に対し効果的であるという報告もある。今回の研究目的は、筋力増強訓練と有酸素運動の実施順序を変える事により、筋力および心肺機能に対してどのような効果の違いを明らかにする事とした。 【対象者と方法】 対象は、研究の説明を受け、同意書に署名した実験上支障が無いと判断された成人男子10名(21.1±0.3 歳)20脚である。運動期間は4週間とし、運動期間の間は2ヶ月間の無運動期間を設けた。有酸素運動(Aerobics training以下、AT)後に筋力増強訓練(Muscle training以下、MT)を行った期間をAM期とし、MT後にATを行った期間をMA期とした。MTは、下肢筋力強化マシンを用い、膝伸展運動を実施した。運動負荷量は、膝関節60度屈曲位での等尺性収縮にて測定した最大膝伸展筋力値(100%MVC)の70%とした。ATは自転車エルゴメーターを用い、運動強度はカルボーネン法を使用し、目標心拍数を50%に設定した。筋力増強の効果判定は大腿周径、最大膝伸展筋力を測定すると同時に、表面筋電図にて大腿直筋、外側広筋の筋積分値(IEMG)を測定した。ATの効果判定はトレッドミルを使用し、呼吸代謝モニターにて最高酸素摂取量(peak VO2)を測定し、AT Windowデータ解析ソフトを用い解析した。統計解析は、大腿周径、最大膝伸展筋力、IEMG、peak VO2についてAM期、MA期での運動実施期間の開始時と終了時の値を各々対応のあるt-検定にて比較した。 【結果】 大腿周径及び最高酸素摂取量はAM期、MA期とも有意差を認めなかった。IEMGは、AM期、MA期各々285.6±171.5V・Sから316.0±248.9V・S、318.8±174.5V・Sから347.3±196.1V・Sと増加したが有意差は認めなかった。膝伸展筋力はAM期に232.3±46.4Nmから209.9±46.0Nmへと低下傾向を認め、MA期は221.7±54.1Nmから276.2+53.8Nmへと有意な増加を認めた(p<0.01)。 【考察】 心肺機能はAM期、MA期ともに有意な効果は認めなかったが、筋力はMA期で増強が認められた。今回の筋力増強は大腿周径に変化はなく、IEMGが増加傾向を示したことから、運動単位動員数の増加によるものであると考えられた。先行研究では、筋力増強訓練の前に有酸素運動を行うことで、筋力増強に必要な成長ホルモンの分泌を抑制するという報告もあり、今回AM期と比較してMA期に筋力増強効果が得られたと考えられた。

We performed physical therapy after reconstruction of the posterior cruciate ligament (PCL) on a Japanese Taekwondo player. In physical therapy after the reconstruction of PCL, we had to protect PCL from mechanical stress. To protect the reconstructed PCL in this case, we predicted the traction stress for PCL by motion analysis using surface electromyography (EMG). In order to avoid the traction stress on PCL, we checked the muscle activity of the quadriceps femoris and the hamstrings during various kinds of muscle strengthening exercises for the lower extremity in the closed kinetic chain (CKC). The muscle contraction of hamstrings with knee flexion caused the posterior displacement of the tibia, and the traction load on PCL was increased with a contraction of hamstrings. On the other hand, because the muscle contraction of the quadriceps femoris produced anterior sharing force of the tibia, the contraction of the quadriceps femoris could protect the PCL from traction load. Therefore, we selected the muscle strengthening exercises in which the muscle activity of the hamstrings was lower and the muscle activity of the quadriceps femoris was higher. Twelve weeks post operation, the muscle strength of the quadriceps femoris had reached a level compatible with returning to competition, and since the patient had no pain or instability of the knee, we had him perform athletic training (jogging, running, step drill, etc.). He could practice athletic training without any pain or feeling instability of the knee. After 19 weeks post operation, we had him perform kick training gradually under the doctor's permission, and to prevent the hamstrings tearing as well as increasing the performance of kicking, we started him on muscle strengthening exercises of the hamstrings with the kick training gradually. After about 27 weeks post operation, the patient could practice all Taekwondo training without any knee pain or feeling instability of the knee, and after about 43 weeks post operation, he competed successfully in the All Japan Taekwondo Championship and becoming. In conclusion, because we selected the muscle strengthening training avoiding traction load on the PCL, the patient could carry out athletic training and Taekwondo training in safety after the operation.
