Description
Technical field
The present invention relates to a kind of medical science analogue experiment installation, particularly a kind of brain injury in rats sensation-balance-motion integrated training devices.
Background technology
Brain injury comprises apoplexy, is common clinical disease, and sickness rate is high, mortality rate is high, disability rate is high and cure rate is low, and its high disability rate causes great burden to patient, family and society.Clinical experiment confirms, the motion of sensation one balance one waits rehabilitation therapy can improve brain injury sequela patient locomotor activity, but its neuromechanism is still not clear, and this hinders the development of rehabilitation medicine to a certain extent.Human experimentation is subject to the restriction of methodology and moral aspect, has larger limitation, very it may be necessary zoopery research.Rat is similar to the gene of the mankind, rat is used to carry out the experiment of simulation physiological pathology of human body state, study the effect of various intervention or rehabilitation means and mechanism, having extremely important effect to the essence and rehabilitation being familiar with disease, is the important means promoting clinical breakthrough.
Domestic and international existing many runways laboratory animal treadmill, U.S. Exer-3/6 animal testing running platform etc., but its function singleness, can only carry out motor function training, and namely post-stroke carries out Aerobic Exercise Training is not in early days inconsistent clinical status.In clinical rehabilitation treatment, apoplexy early stage patient cannot complete active exercise, and therapist gives outside passive manipulation, also often allows the material of limbs of patient friction, touch, the different feel of impression and quality, it is trained to distinguish object ability, to promote that its sensory function is recovered.Treat that patient's muscular strength and sensory function are recovered to some extent, after independently standing, because its muscular strength still can not meet motion needs, therefore first give balance function training, comprise balance plate training etc.After patient's muscular strength recovers further, patient is just allowed to carry out active exercise training.For rehabilitation of stroke patients treatment, the theory of modern rehabilitation, not only for the improvement of motor function, also needs the improvement comprising sense of touch and static sense.Impercipience is fed back, and patient is difficult to normally regulable control motion, maintains posture and keep balance.Feel in the training process, to balance and training can not be well-separated, the concept that sensation one balances a training integration must be set up.
Therefore, research and develop a kind of novel multi-functional rat device for healing and training meeting modern rehabilitation medicine theory, the training such as sense culture, balance function training, motor function for rat or other animals is significant.Multi-functional rat device for healing and training both can carry out single treadmill training, sensation one can be implemented again balance an exercise rehabilitation training method and combine, simulate the multifunction rehabilitation training pattern feeling balance one motion clinically truly, can also experimentally require flexibly to select velocity, sway velocity, training time etc., quantize training burden, meet the experiment demand of researcher, the neuromechanism rehabilitation research that the sensation one for brain injury disease balances a motion and combination treatment thereof provides advanced zoopery means.
