Consequences of neck manipulation performed by a non-professional

Biomechanical analysis of successful versus unsuccessful free throw shots performed by professional basketball players

The main purpose of the present study was to investigate the kinematics and kinetics of successful versus unsuccessful basketball free throw shots. Six professional basketball players (age= 23±2.09 years members of Iranian premier basketball league participat in test. Kinematics of arm motion during basketball free throws were recorded by two Casio zr200 camera in frequency of 240 Hz. Wilcox...

Cooperative elastic object manipulation performed by virtual joystick operation

This paper presents a virtual manipulation environment dealing with elastic objects. An original fast computation elastic model ‘the gradational resolution model’ is introduced for real-time interaction, in which the number of elastic elements are efficiently reduced for acceleration. Joystick force feedback is used for sensible interaction. Two kinds of collision algorithms are examined by joy...

Neck manipulation as a cause of stroke.

Cerebrovascular complications of neck manipulation.

The safety of spinal manipulation is an issue that demands regular and rigorous assessment, as manipulation of the upper spine has been associated with serious adverse events such as cerebrovascular accidents due to cervical artery dissection. A correlation between stroke and cervical manipulation has been reported with increasing frequency, and each new report seems to reignite debate between ...
