Use of the BFB-PT training device

Neurology - conditions after a stroke, cerebral palsy (ICP), peripheral neuropathies, craniocerebral injuries, Parkinson's disease, impaired coordination of movements, muscle contractures

Traumatology/Orthopedics - restoration of joint mobility after prolonged immobilization of limbs, after joint injuries, fractures, burns, after osteosynthesis, endoprosthesis replacement, for recovery and training of tendons, for joint development after surgery.

Physical therapy - increasing motivation for exercise, monitoring the correctness of exercise procedures.

Cardiology - after a heart attack.

Sports/Fitness - control the correctness of the exercises.

 

Capabilities of the BFB-PT training device

- registering joint movements

- assessing degree of contracture and development

- training of joint movements in all possible directions

- simultaneous training of several segments (for example, flexion-extension in ankle and hip joints)

- spine training

- balance training

- displaying the status of the monitored function in real time and training this by BFB in play mode

- controlling the correctness of exercises

- regulating loads based on the patient's physical condition

- creating individual training patterns for particular muscle groups

- documenting the results and assessing the recovery progresss

 

The BFB-PT training device includes wireless biomechanical sensors, which let you record movements, position, speed and angular values ​​in joints. These biomechanical parameters are trained due to special physical exercises in play mode, based on the BFB method, when the feedback to the patient's actions is displayed in real time. This ensures control of the correctness of the exercises and creates favorable conditions for the patient's active participation in the rehabilitation process. The training of movements can be used in all possible directions and, if there are enough sensors, in all large joints of a limb at the same time. Thus, an opportunity is created to develop contractures, restore biomechanics of movements, including training the skills for walking. In addition, muscle trophicity is improved, fracture consolidation is accelerated, muscle atrophy is prevented.

Trust-M biomechanical sensors high frequency register the angles of inclination and determine the spatial position of the segments. By placing the sensors on different body segments (head, torso, chest), you can perform exercises selected by the doctor for different parts of the spine - forward, backward, right, left, twisting. The results of the training are back muscles strengthening, spine stability increasing in the trunk and waist, pain reduction, improving coordination of motions, flexibility, joints recovery of the spine, correct motor stereotypes formation. 

To conduct balance training, you can set the angle of inclination of the body and smoothly dose the load. It is possible to use an additional platform for to improve the effectiveness of such exercises, more detailed in the section of "Balance System TrustMotion".

The convenient software of the BFB training device allows you to create individual training schemes for certain muscle groups, document the results in the form of visual tables and estimate the dynamics of recovery.

 

Benefits of the BFB-PT training device 

- autonomous biomechanical sensors to record motion parameters with EMG and FES functions

- the possibility of combination with orthoses and mechanical training equipment

- tracking movements in 3 planes

- development of joint contractures in the 3 axes of rotation

- modified versions for recumbent patients with the possibility to use a VR helmet

- lack of special room requirements, may be used at home

 

In addition to recording movement parameters, "Trust-M" biomechanical sensors provide for the registration of electromyograms and tremors enabling muscle tone to be assessed, asymmetries to be identified, spine load distribution to be assessed and rehabilitation exercises selected correctly. Moreover, it makes it possible to train muscle activity using the BFB method, which significantly increases exercise effectiveness. See details on the BFB-EMG training device.

The sensors provide the function of electrostimulation, which, if necessary, can become an additional method of effect on muscles. So, for example, to generate a hand grip function, an electrical impulse is applied to the muscle in the desired phase of muscle contraction.

"Trust-M" sensors can be combined with orthoses to fix joints and to regulate scope of movement, as well as with exercises on mechanical training equipment.

All movements are monitored in three planes, and rotations are recorded in three axes. This enables all kinds of movements in joints to be evaluated and trained - flexion and extension, abduction and adduction, pronation and supination.

Autonomous wireless sensors "Trust-M" small in size and lightweight, do not restrict movements, can be easily attached to the patient's body, and provide for comfortable use.

When a doctor prescribes a set of therapeutic exercises, the patient himself can use the trainer at home.

The BFB-PT training device which uses a virtual reality helmet is great for rehabilitating motor functions in bedridden patients.
