  • This invention relates to motion analysis. More particularly, the invention relates to a motion analysis system and to a method of analysing motion.
  • each moving element has to the overall desired motion of the body. This is important, whether the body is a piece of machinery with a number of moving components that may interact or whether the body is a human being performing simple motion like walking or complicated motion as may be the case in playing sport.
  • the ability to monitor and analyse the overall motion by analysing the motion of some moving parts provides the opportunity to identify aspects of the overall movement that affect the efficiency and functionality of the overall movement.
  • this may assist in identifying those parts of the machinery that experience undue force during operation to aid in explaining why such parts fail in the way they do.
  • it may be possible to identify limb movements which are deficient or which greatly affect or reduce the efficiency of a simple action such as walking or standing still. This may be particularly important for individuals such as professional athletes who may wish to analyse their motion in great detail to ensure that they are performing to their optimal level or to improve their performance. Equally, individuals suffering from physiological disorders may also wish to analyse their motion in detail to ensure that assistance can be applied to those areas where help is needed.
  • a system would make gait analysis far more widely available for those individuals requiring such careful gait monitoring and analysis.
  • Such a system could also be used to analyse real-time motions associated with sporting activities or everyday motions related to various physiological disorders including balance disorders or medication effectiveness associated with diseases such as Parkinson's Disease.

  • each sensor may include signal modifying capabilities for modifying a signal resulting from an out-of-range measurement to cater for extremes in the parameters being measured.
  • This aspect is particularly useful due to high peak values arising in certain circumstances such as, for example, impact of a person's foot with the ground when walking or running.
