Telerehabilitation-based Motor Imagery in Nonspecific Low Back Pain

The Kinesthetic and Visual Imagery Questionnaire-Short Form consists of 10 movements in total, measuring 5 visual and 5 kinesthetic visualization skills, developed to determine the extent to which individuals visualize and feel the imagined movements. The questionnaire is not a self-report scale, but is administered with an evaluator. All movements are evaluated in the sitting position. Higher scores indicate greater visual clarity or intensity of sensations.

The Movement Imagery Questionnaire-Revised assesses visual and kinesthetic movement imagery ability and is comprised of four visual and four kinesthetic items. Each item entails performing a movement, visually or kinesthetically imaging that movement and then rating the ease or difficulty of generating that image on a 7-point scale from 1 = very hard to see/feel to 7 = very easy to see/feel. Higher scores indicate higher visual or kinesthetic movement imagery ability.

The Oswestry Disability Questionnaire, which allows the patient to self-evaluate, is used to evaluate the limitations that patients compare in daily life. The total score ranges from 0 to 100, and a high score indicates an increased level of disability.

It is grouped as Low (Category 1), Medium (Category 2), Very active (Category 3). Calculation is made on a weekly basis as MET level x minutes of activity.

Visual analog scale (VAS) is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points.

In this test, the patient is asked to repeat the digits read to him, one second apart, in the same order backwards, starting from the last. The test starts with a two-digit number sequence, and when repeated correctly, one digit is increased and continues until the seventh sequence of eight numbers. The patient must repeat at least one of the two sequences of numbers of the same length in the correct order in order to progress in the test. Scoring is based on the total number of correct and repetitions.

The test form consists of 14 lines, each with 47 marked letters. There are 16 letters "p" and "d" marked with one, two, three or four lowercase lines in each line. The patient is asked to find and cross out the letters "d" with only two signs. For each line, the patient is given 20 seconds.

The Trail Making test consists of two parts. In Part A, the patient is asked to put together the circles with numbers in the correct order, which are scattered on the test form. In Part B, the patient is asked to combine the circles, which are scattered on the test form and contain both numbers and letters, in the correct order (1-A, 2-B, 3-C).

The Pittsburg Sleep Quality Index evaluates sleep quality over the past month. 19 of the 24 questions included in the Pittsburg Sleep Quality Index are self-report questions. Five questions are answered by the spouse or a roommate. The 18 items participating in the scoring are grouped into 7 component scores. Each item is evaluated over 0-3 points. The sum of the 7 component scores gives the overall Pittsburg Sleep Quality Index score.

The SF-36 has a total of 8 sub-components: physical function, physical role limitation, pain, general perception of health, vitality (energy), social function, emotional role limitation, and mental health. The answers to the questions answered by the participants are scored between 0-100. A high score indicates a good quality of life, and a low score indicates a poor quality of life.
