The model was then tested in simulated hyperflexion and hyperextension injuries and the cord strains and strain rates measured. In flexion, the strains were found to be in excess of critical values for isolated neural tissue damage. In extension the strains were found to be smaller, and less ...
Objective:To observe the effect of self-created hyperextension exercise therapy on improving flexion and extension malfunction of the spine in patients with ankylosing spondylitis(AS).Methods:Sixty patients with AS were enrolled in this study from December 2007 to November 2009.According to the visiting...

We hypothesized that based on the frequent presentation of opisthotonos in patients with hindbrain hernia (primarily Chiari II malformation but sometimes Chiari I malformation) that the hyperextension might be a compensatory technique used by such patients to bring the cerebellar tonsils up out of the...

Congenital clasped thumb in palm corresponds to a spectrum of anomalies leading to a loss of thumb extension and abduction. Intrinsic muscles and skin shortening are not infrequent. Conservative orthopedic treatment should be undergone as soon as possible. When this treatment fails, or when patients...
Briefly Define: Hyperextension How would you describe the extra movement possible at the knee with a torn posterior cruciate ligament? Identify and describe common patellofemoral pathologic conditions of the knee. Explain why the crossed extension reflex must accompany a withdrawal reflex of ...
reported that knee loading was greater in hyperflexion and that the medial collateral ligament was more affected in hyperextension of the femoral prosthesis [23]. With respect to mobile prostheses, the majority of scholars consider distal femoral anteversion to fall within the range of 0°--15° ...
phase function, compensatory mechanisms are necessary. Progression may be augmented through a premature heel rise, forward trunk lean, knee hyperextension, or a combination thereof. The inability to achieve a neutral ankle position during swing also necessitates compensatory movements to ensure foot ...
