Description

A kind of rehabilitation training of upper limbs system and method using virtual reality technology
Technical field
The present invention relates to medical treatment & health technical fields, specifically, more particularly to a kind of using the upper of virtual reality technology Limbs rehabilitation training system and method.
Background technique
Traumatic nerve injury such as traumatic brain injury, spinal cord injury, the cranial vascular diseases such as apoplexy are the main of people's physical disabilities Reason.Patient with cerebral injury, spinal cord injury can generally lose the control to body upper limb part.There is upper extremity exercise to allow The patient of obstacle obtains best rehabilitation efficacy, and rehabilitation training just must have specific aim and challenge.Meanwhile rehabilitation training is One arduous process, patient repeats to adhere to just can be effective.Therefore, how to allow patient not feel uninteresting in training is also very Important.Currently, rehabilitation therapy is other than traditional training for carrying out teach-by-doing to patient by rehabilitation therapist, there are also some Patient carries out supplemental training using healing robot.However these recovery training methods suffer from obvious disadvantage: patient is only Rehabilitation training simply can be passively participated in, process is very dry as dust.Therefore, patient participates in the initiative of training, enthusiasm not By force, trained effect is undesirable.Meanwhile a rehabilitation therapist can not carry out rehabilitation training to several patients simultaneously, greatly Waste human and material resources.
Virtual reality technology abbreviation VR technology, also referred to as clever mirror technology or artificial environment.It resulted from for 20th century 60 years earliest Generation, Sutherland be put forward for the first time shown including interactive graphics (IG), the virtual reality system of device for force feedback and auditory tone cues Basic thought.Virtual reality technology simulates the virtual world for generating a three-dimensional space using computer, provides pass for user In the simulation of the sense organs such as vision, allow user that can observe the things in three-dimensional space immediately, without limitation.Based on functionality The studies have shown that of magnetic resonance imaging can induce the cerebral cortex of paralytic based on the training rehabilitation system of virtual reality technology It is recombinated.
Summary of the invention
According to the prior art set forth above technical problem dry as dust for rehabilitation training of upper limbs, and provide a kind of application The rehabilitation training of upper limbs system and method for virtual reality technology.The present invention is mainly provided using virtual reality technology for rehabilitation training Duplicate practice and in real time feedback, make patient have stronger feeling of immersion, improve the enthusiasm that patient carries out rehabilitation training, make Patient is ready to be actively engaged in rehabilitation training, and then promotes the efficiency and effect of rehabilitation training, shortens the rehabilitation training time of patient.
The technological means that the present invention uses is as follows:
A kind of rehabilitation training of upper limbs system using virtual reality technology, comprising:
Hand exercise data acquisition module, using Leap Motion infrared detector;
Game engine modules, using Unity engine and PhysX physical engine;
Interactive engine module, using the Interaction Engine of Leap Motion;
Virtual reality device module shows equipment using the end PC display or HTC Vive, OCulus virtual reality head;
Hand motion when the hand exercise data collecting module collected tracking patient motion, and be synchronized to described Game engine modules by the hand motion information reconstruction of patient in the virtual environment of the virtual reality device module, then are led to It crosses interactive engine module and realizes operation of the hand motion of patient to object in game.
Further, the game design of the virtual reality device module targetedly trains outpost, and the training is closed Card is related to different task objects, and the difficulty at training outpost is incremental.
Further, the Leap Motion infrared detector can be when tracking the hand motion of patient, without giving Patient dresses other devices, removes additional hand burden from.
The present invention also provides a kind of rehabilitation training of upper limbs methods using virtual reality technology, include the following steps:
Step S1: installing and debugs the Leap Motion infrared detector of good hand portion tracking, keeps Leap Motion red Outer detecting devices can accurately track patient hand's movement and relevant action information is correctly passed to game engine modules;
Step S2: by game engine modules by the hand motion information reconstruction of patient in the virtual reality device module Virtual environment in;
Step S3: by the upper extremity exercise data of hand exercise data collecting module collected patient, and judge the fortune of patient It is dynamic whether to reach rehabilitation standard, if reaching rehabilitation standard, the upper extremity exercise data of patient are transmitted to interactive engine module, are led to Crossing interactive engine module makes the upper limks movements of patient realize the operation to Objects In A Virtual Environment;
Step S4: if patient, which has reached a series of preset task objects, rehabilitation training in virtual environment, to terminate.
Further, the step S4 further includes following steps:
Step S41: during completing task object, if the hand motion of patient does not complete specified requirement, triggering failure Special efficacy, then train outpost to reset, and patient is challenged again;
Step S42: during completing task object, if the hand motion of patient completes specified requirement, triggering clearance is special Effect, will be automatically loaded new training outpost;
Compared with the prior art, the invention has the following advantages that
1, the rehabilitation training of upper limbs system provided by the invention using virtual reality technology, by designing specific aim for patient Training outpost, allow patient to obtain special training in gaming, improve the efficiency of patient's training rehabilitation.
2, the present invention mainly provides duplicate practice and in real time feedback using virtual reality technology for rehabilitation training, makes to suffer from Person has stronger feeling of immersion, improves the enthusiasm that patient carries out rehabilitation training, patient is made to be ready to be actively engaged in rehabilitation training, into And the efficiency and effect of rehabilitation training are promoted, shorten the rehabilitation training time of patient.
3, studies have shown that the rehabilitation training of the upper extremity function of hemiplegic patient should carry out under positive environment, it is passive or Not positive training, it is very unobvious to the rehabilitation efficacy of the remodeling of patient's brain function and hand movement function.On provided by the invention Limbs rehabilitation training system can make hemiplegic patient carry out correct hand rehabilitation training under positive environment, accelerate patient's brain function It can remold and hand movement function restores, patient is made to have reached good rehabilitation efficacy.
4, the studies have shown that based on functional magnetic resonance imaging be based on rehabilitation training of upper limbs system provided by the invention can be with The cerebral cortex of induction paralytic recombinates.Also some researches show that for patient, using upper limb health provided by the invention Multiple training system can be more more efficient than traditional upper limb healing system, can relatively make using the patient of virtual reality upper limb healing technology Preferably restored in terms of upper limb disorder with the patient of Traditional Rehabilitation system, relevant locomitivity becomes stronger.
The present invention can be widely popularized in fields such as medical treatment & healths based on the above reasons.
