purpose: core stability and leg stiffness are two determinant mechanisms in athletic performance and risk injury. this study aimed to investigate the gender differences and relationship of these two factors in athletes. methods: in this cross-sectional study, core stability and leg stiffness of 12 male and 12 female iranian squash players at national level were examined utilizing mcgill’s test ...

The stiffness of a parallel manipulator is not only concerned with its detailed structure but also affected by the allocation scheme of actuators. Even though the precise values of stiffness cannot be derived since the link structure is not definitive at the stage of mechanism design, the effect of the allocation of actuators on the mechanism stiffness can be qualitatively evaluated in order to...

The clinical features of 10 cases of lateral trunk muscle injury in first class cricket pace bowlers are described. Typically the injury occurs during a single delivery, is associated with considerable pain, and prevents the bowler from continuing. The clinical picture is typical of a muscular or musculotendinous injury. The most consistent clinical tests were focal tenderness on palpation and ...

Rotator cuff lesions (RCL) have considerable variability in location, tear pattern, functional impairment, and repairability.Historical classifications for differentiating these lesions have been based upon factors such as the size and shape of the tear, and the degree of atrophy and fatty infiltration. Additional recent descriptions include bipolar rotator cuff insufficiency, 'Fosbury flop tea...

Groin pain may stem from a variety of different causes. Adductor tendinopathy is a common but infrequently recognised cause of chronic groin pain especially in athletes. This case report describes a case of clinically suspected adductor tendinopathy in an amateur athlete confirmed by MRI (Magnetic Resonance Imaging). Relevant literature on musculotendinous injuries of the groin along with diffe...

VOL. 74-B, No. 2, MARCH 1992 tendon. Squeezing the calf was seen to deform the fleshy soleus causing the overlying gastrocnemius tendon to bow away from the tibia resulting in plantar flexion (Fig. 1). There was no longitudinal movement of the soleus while the gastrocnemius muscle bellies moved about 1 cm proximally, confirming our ultrasound findings. When the soleus tendon was divided the pro...

Popliteal artery entrapment syndrome is an important, albeit infrequent, cause of severe disability among young adults and athletes with anomalous anatomic relationships of the musculotendinous structures surrounding the popliteal artery. We report a case where duplex ultrasonography and dynamic magnetic resonance arteriography was used to diagnose popliteal artery entrapment. We used a posteri...

CP is the most common cause of chronic disability in childhood occurring in 2-2.5/1000 births. It is a severe disorder and a significant number of patients present cognitive delay and difficulty in walking. The use of botulinum toxin (BTX) has become a popular treatment for CP especially for spastic and dystonic muscles while avoiding deformity and pain. Moreover, the combination of physiothera...

BACKGROUND The purpose of this study was to determine the relative contribution of fibrosis-mediated and myofibril-mediated stiffness in rats with mild and severe right ventricular (RV) dysfunction. METHODS AND RESULTS By performing pulmonary artery banding of different diameters for 7 weeks, mild RV dysfunction (Ø=0.6 mm) and severe RV dysfunction (Ø=0.5 mm) were induced in rats. The relativ...

Cells from many different tissues sense the stiffness and spatial patterning of their microenvironment to modulate their shape and cortical stiffness. It is currently unknown how substrate stiffness, cell shape, and cell stiffness modulate or interact with one another. Here, we use microcontact printing and microfabricated arrays of elastomeric posts to independently and simultaneously control ...
