N/A Parkinson's disease. Intervention group: First, each patient will be examined by a neurologist before starting the test and the degree of their movement disorder will be determined, then the degree of improvement of the patient's movement disorder will be examined separately or together after using visual, auditory and vibrational feedbacks .In order to evaluate these feedbacks, we have created a device in this field that provides all three required outputs.In this device, a rhythmic auditory pulse based on the number of pulses per minute is used for the auditory indicator.In the visual part, two linear lasers (step-by-step lighting) are used, which are connected to the patient's knee .It should be mentioned that the length of the step can be adjusted based on the patient's ability. Such activation of each laser is done by two sensors that are connected to the heel of the patients.In the following, the functional improvement of patients is measured with the help of sensory and vibrational feedback .Sensory-vibration feedbacks can be evaluated in a dependent or separate manner in such a way that a rhythmic vibrational pulse that can be dependent on the auditory marker is created or based on the patient's steps used by the sensors in the heels, to be activated.. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is in the process of publishing this trial i would get access to personal information to publisher if their was requested.
