Neuroscience based proprioceptive exercise trainig using laser pointer (nbpet) is a new aproach exercise training method. In this study, This study aimed to investigate the effects of nbpet using laser pointer on different fonctional parameters.
This study aim to investigate the effects of nbpet using laser pointer on different fonctional parameters.
Participants will divide into two groups (experimental and control ). Joint position errors will evaluate with the jonit position error assessment method, range of motion with a goniometer, kinesiophobia with the Tampa kinesiophobia scale, pain with the Mc Gill pain scale, quality of life with the Older People Quality of Life questionnaire (OPQoL-brief), and mobility with the time up and go test. Both groups will include in the exercise program with proprioceptive exercise training for 2 sessions per week for 6 weeks. In addition, the experimental group will train with nbpet using laser pointer at the same time.
Properioceptive training A proprioceptive training regimen will establish with Swiss balls. The proprioceptive activities is advanced on a weekly basis in order to test the patient\'s balance in response. Patients have training in three stages: beginning, intermediate, and advanced. Each exercise will perform as 3x10 repetitions. Between sets, 2-3 minutes rest breaks will given. The beginning phase will applied in the 1st and 2nd weeks, the intemediate phase in the 3rd and 4th weeks, and the advanced phase in the 5th and 6th weeks. The proprioceptive rehabilitation protocol is based on a previous study. All the program will conducted by one experienced physiotherapist.
Neuroscience based proprioceptive training using laser pointer A pre-created wallpaper indicating various directions will fix on the wall 90 cm away from the patient (at the level of the patient\'s knee when the patient was standing upright) . Then, the laser pointer (producted by NMC training system) will fix to the patient\'s knee with the help of a velcro so as not to interfere with the patient\'s knee movement.
At the beginning of the exercise, the patient is asked to move the light on the laser pointer to the midpoint of the wallpaper. The patient is then asked to follow the instructions on the wallpaper by moving the knee in flexion-extension, medio-lateral directions. These instructions are continued throughout the exercise in different directions. Meanwhile, the patient is asked to perform mild cognitive tasks such as counting numbers, names of people starting with any letter, city names or animal names. The training continues for approximately 20 minutes.
2,930 studies on the registry are indexed under Chronic Pain; 701 are open to participants now.

pain meausere
Short-form McGill Pain Questionnaire (SF-MPQ) will used to examine pain level of participants. The main component of the SF-MPQ consists of 15 descriptive adjectives for the pain sensation (11 sensory and 4 affective), which are self-rated by the patient according to their intensity level on a point rating scale (0 = none,1 = mild, 2 = moderate, 3 = severe). Three pain scores are derived from the sum of the intensity rank values of the words chosen for sensory, affective and total descriptors. The total score is the sum of the intensity values.
Time frame: 6 weeks
position error
Joint Position Error measurement will used to asses knee proprioception of elderly. It is a test performed with a wall-mounted board consisting of circles drawn at a distance of 1 cm from the patient and a laser placed on the patient's knee with appropriate belts. After the laser is placed on the patient's knee, the patient stands and tries to hold the laser light at the starting point with eyes open on the board placed 90 cm away. The patient is first asked to perform 10 repetitions of knee flexion and extension and then to return the laser to the starting position with eyes closed. In the final stage, the patient's horizontal, vertical and global distance from the laser light starting point is recorded in cm
Time frame: 6 weeks
Range of motion
Knee range of motion assesment: Knee range of motion (KROM) will assesed using a standard goniometer, consisting of a protractor body with two arms (one stationary and one movable), was used for all measurements. Participants are positioned supine on a flat examination table For knee flexion measurements, participants are instructed to lie supine with the hip of the leg being measured in a neutral position. The fulcrum of the goniometer is placed over the lateral epicondyle of the femur, the stationary arm is aligned with the greater trochanter of the femur, and the movable arm is aligned with the lateral malleolus of the fibula
Time frame: 6 weeks
Qualitiy of life
Older People Quality of Life questionnaire (OPQoL-brief): OPQoL-brief will used to evaulate quality of life. A shortened version of OPQoL-brief was developed by Bowling et al. The OPQoL-brief consisted of 13 statements, with the participants being asked to indicate the extent to which they agree with each statement by selecting one of five possible options ("strongly disagree," "disagree," "neither agree nor disagree," "agree," and "strongly agree"). The range in the original version is based on the principle of point allocation. The items are summed to provide a total OPQoL-brief score. The total score of OPQoL-brief ranges from 13 to 65 and higher scores indicate better QoL. Te OPQoL - brief questionnaire also includes a preliminary single item on global OoL. This single item is not scored with the OPQOL; it is coded as very good (5) to very bad
Time frame: 6 weeks
Kinesiophobia
Tampa Scale for Kinesiophobia (TSK): The TSK-11 will used to asses kinesiophobia. This scale consists of 11 questions. A 4-point Likert scale assigns a score to each item, which includes strongly disagree, disagree, agree, and strongly agree options. The total score ranges from 11 to 44. A high score indicates a high level of kinesiophobia. Individuals were asked to tick the appropriate box for each question, and the total score was calculated.The lowest score on this scale is 11 and the highest score is 44. The higher the score, the higher the kinesiophobia.
Time frame: 6 weeks
Time up and Go test
The Time up and Go test (TUG): The TUG will used to evaluate mobility. The TUG is a balance and gait index which requires the patient to stand up from a chair, walk a 3 m distance, turn, walk back to the chair, and sit down. The time required to complete the task is measured in seconds
