Muscle activation patterns in acceleration-based phases during reach-to-grasp movement.

[Purpose] An earlier study divided reaching activity into characteristic phases based on hand velocity profiles. By synchronizing muscle activities and the acceleration profile, a phasing approach for reaching movement, based on hand acceleration profiles, was attempted in order to elucidate the roles of individual muscle activities in the different phases of the acceleration profile in reaching movements. [Subjects and Methods] Ten healthy volunteer subjects participated in this study.

Injuries and disorders among young ice skaters: relationship with generalized joint laxity and tightness.

This study retrospectively investigated 192 teenage speed and figure skaters with prior injuries documented by an athletes' questionnaire, who underwent a physical examination to assess their muscle tightness and generalized joint laxity. In all athletes, the degree of muscle tightness and joint laxity were measured by a standardized physical examination. A descriptive report of the types of injuries showed a predominance of fractures, ligament injuries, enthesitis, and lower back pain.

Toe-out angle changes after total knee arthroplasty in patients with varus knee osteoarthritis.

Purpose: Toeing-out is a commonly proposed kinematic variable that has been suggested to reduce external knee adduction moment. Analyses of the toe-out angle after total knee arthroplasty (TKA) are useful for obtaining a proper understanding of the abnormal gait caused by varus knee osteoarthritis (OA), as well as performing rehabilitation after arthroplasty. Changes in the toe-out angle after arthroplasty have not yet been defined or analysed.

A clinical study of the efficacy of a single session of individual exercise for depressive patients, assessed by the change in saliva free cortisol level.

Background: The efficacy of physical exercise as an augmentation to pharmacotherapy with antidepressants for depressive patients has been documented. However, to clarify the effectiveness of exercise in the treatment of depression, it is necessary to distinguish the effect of the exercise itself from the effect of group dynamics. Furthermore, an objective measurement for estimation of the effect is needed.

Influence of inhaled procaterol on pulmonary rehabilitation in chronic obstructive pulmonary disease.

Background: Chronic obstructive pulmonary disease (COPD) is a progressive condition that classically causes dyspnea during physical activity. Destruction of alveoli and bronchostenosis are thought to lead to shortness of breath and result in decreased physical activity. In this study, we examined the influence of inhaled procaterol on exercise therapy for pulmonary rehabilitation.

Immediate effects of physical therapy on gait disturbance and frontal assessment battery in Parkinson's disease.

Aim: To examine whether the Frontal Assessment Battery is associated with the immediate effects of physical therapy on gait disturbance in patients with Parkinson's disease.

Methods: A total of 18 patients with idiopathic Parkinson's disease (Hoehn and Yahr stage range 3-4) who were able to ambulate independently and who were not demented were included. Patients were divided into two groups on the basis of Frontal Assessment Battery scores: the high score group (score ≥ 13, n=11) and the low score group (score ≤ 12, n=7).

Anatomical evaluation of the rectus femoris tendon and its related structures.

Purpose: The purpose of this study was to evaluate the anatomical structure of the quadriceps tendon in detail for use as an anterior cruciate ligament (ACL) graft tendon.

ACL footprint size is correlated with the height and area of the lateral wall of femoral intercondylar notch.

Purpose: The purpose of this study was to reveal the correlation between the size of the native anterior cruciate ligament (ACL) footprint and the size of the lateral wall of femoral intercondylar notch.

Methods: Eighteen non-paired human cadaver knees were used. All soft tissues around the knee were resected except the ACL.

Graft impingement in anterior cruciate ligament reconstruction.

Anterior cruciate ligament (ACL) graft impingement is one of the most troubling complications in ACL reconstruction. In the previous strategy of isometric "non-anatomical" ACL reconstruction, posterior tibial tunnel placement and notchplasty were recommended to avoid graft impingement. Recently, the strategy of ACL reconstruction is shifting towards "anatomical" reconstruction.

Size comparison of ACL footprint and reconstructed auto graft.

Purpose: The purpose of this study was to compare the size of native anterior cruciate ligament (ACL) footprints and the size of commonly used auto grafts. The hypothesis was that the reconstructed graft size with auto grafts might be smaller than the native ACL footprint.

Methods: Fourteen non-paired human cadaver knees were used.
