The Effects of Neuroscience Based Proprioceptive Exercise Training

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.

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

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

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

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.

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
