OBJECTIVE To confirm previous findings that hip abductor activity measured by electromyography (EMG) on the side contralateral to cane use is reduced during walking in stroke patients. To assess whether an orthosis (TheraTogs) or hip abductor taping increase hemiplegic hip abductor activity compared with activity during cane walking or while walking without aids. To investigate the effect of ea...

A 63-year-old male consulted our institution due to worsening of right hip pain for approximately one month. The patient had no apparent functional disorders besides rigidity of the right ankle secondary to childhood poliomyelitis. Plain radiographs demonstrated narrowing of the right hip joint space. Magnetic resonance imaging (MRI) showed unusual findings in the right gluteus medius muscle, s...

Electrical stimulation of the lateral gastrocnemius-soleus (LGS) nerve at group I afferent strength leads to adaptations in the amplitude and timing of extensor muscle activity during walking in the decerebrate cat. Such afferent feedback in the stance leg might result from a delay in stance onset of the opposite leg. Concomitant adaptations in hip abductor and adductor activity would then be e...

A few papers develop full-fledged methods to estimate LG models. Binsbergen and Koijen (2009) study a LG model with time-varying risk premium and growth rate of stocks. Bekker and Bouwman (2009) estimate a three-factor LG term structure model. Carr, Gabaix and Wu (2009) show how calculate options in closed form in a LG term structure model, and perform an empirical analysis of bonds and fixed-i...

background: single leg drop landing is one of the common sport activities that have greater likelihood of leading to traumatic oflower extremity. however, there is limited understanding of biomechanics of this maneuver. hence, this study aimed to compare the activities of lower limb muscles during pre- and post phases of single leg drop landing. methods: this semi-experimental research of 13 ph...

Recently, clinicians have focused much attention on the importance of hip strength for the rehabilitation of not only patients with low back pain but also lower extremity pathology. Properly designing a rehabilitation program for the gluteal muscles requires careful consideration of biomechanical principles, such as length of the external moment arm, gravity, and subject positioning. Understand...

Background and Aims Athletic groin pain (AGP) is one of the most common injuries among athletes. It causes use compensatory mechanisms to adjust affects lumbar-pelvic hip movements, which leads prolonging healing process. This study aims compare timing electromyographic activity in selected muscles during a cross-cutting maneuver football players with AGP healthy peers. Methods In this quasi-ex...

Surnrn~~ The presence of a trigger point is essential to the myofas~iai pain s~drom~. This study centres on identifying clearer criteria for the presence of trigger points in the quadratus Iumborum and gluteus medius muscle by investigating the occurrence and inter-rater reliability of trigger point symptoms. Using the symptoms and signs as described by Simons” 1990 definition and two other for...
