Background
Low back pain is one of the most important causes of morbidity in all countries of the world, and 80–85% of people experience low back pain at least once during their lives [1]. The lifetime prevalence of low back pain is between 43–51% [2, 3, 4]. Non-specific lower back pain limits the activity of adults younger than 45 years especially in industrialized countries, and it is one of the leading reasons for consulting a doctor [4].
Many conservative methods are recommended with a multidisciplinary approach for the treatment of low back pain. Cognitive behavioral therapy, supervised exercise programs, brief patient education program, back schools, mobilization/manipulation techniques and physical therapy modalities are the most widely used methods [5].
Physical therapy modalities used in rehabilitation programs are effective in the reduction of pain and improvement of functionality in the treatment of chronic low back pain [6, 7, 8, 9]. The effectiveness of the treatment is increased when exercise therapy is applied together with physical therapy modalities [9]; exercise therapy should, therefore, be included especially in the treatment of chronic low back pain [9, 10].
There has been a limited number of studies investigating the efficacy of specialized treatment techniques commonly used by physiotherapists in the treatment of chronic low back pain. Kinesio
In this study, it was aimed to determine the effect of Kinesio
Methods
The study included patients who presented at Yalova State Hospital, Department of Physical Therapy and Rehabilitation and were diagnosed with chronic low back pain by a physician.
The study was approved by Marmara University, Institute of Health Sciences Ethics Committee and was conducted in compliance with the Helsinki Declaration. Written informed consent was obtained from all patients.
Patients older than 18 years with pain caused by a herniated disk and mechanical low back pain ongoing for at least three months were included in the study. Patients who met any of the following criteria were excluded from the study: receiving any other treatment for low back pain at the time of the study, allergic reaction to the taping, any contraindications for physical therapy modalities or exercise, primary or metastatic neoplasm on spine or other tissues, previously spinal surgery for any reason, infectious pathologies in the spine or inflammatory diseases with spine involvement, radiculopathy, prolonged immobilization that could lead to muscle atrophy, or steroids and similar drugs usage.
The randomized patient list of three groups was created with the internet-based “Randomizer” program. Patients admitted to the clinic were allocated to the groups in the order in which they arrived. A total of 10 treatment sessions were applied to the patients in all three groups, five days per week for two weeks in the Physical Therapy and Rehabilitation Unit. In each session, therapeutic ultrasound (1 MHz, 1.5 W/cm

Taping method.
The KT relaxation technique (Fig. 1) was applied to the patients in the Group 1 (tape group) at the end of each treatment session. The patients were asked not to remove the tapes which were then removed by the physiotherapist in the next session, and new taping was applied after the treatment. Placebo taping was applied to the patients in Group 2 (placebo tape) at the end of each session. Taping was not applied to the patients in Group 3 (control).
In the taping group, patients were positioned so that it was possible to reach the maximum available stretch of the lumbar spine and the surrounding soft tissues and skin. Thus, with the patient standing, they were requested to flex forward as far as possible. The tape of 5 cm width was applied horizontally over the dimples of the back and the second band of tape of the same width was applied immediately above the first tape. When applying the bands, the tension was zero at the beginning and end, but the tape was stretched to 35%–40% of its length over the back. The same physiotherapist applied all the tapes. In the placebo group, the same form of taping was applied horizontally over the dimples of the back but with no tension in the tape.
For each patient, age, height, weight, body mass index (BMI), and gender were recorded on evaluation forms prepared by the researchers before the treatment. All the evaluations were repeated after the 10 sessions of treatment.
Pain was recorded by the participant using a 10-cm visual analog scale, where 0 represented no pain and 10 represented unbearable pain.
For the assessment of disability, the Oswestry Disability Index was used. This scale contains 10 items related to limitations in daily life activities, with each scored on a 0–5 point scale; the total points are then converted to a percentage [14].
Sit and reach test.
The sit and reach test was used to evaluate trunk flexibility. This test involves the patient sitting on the floor or treatment table with legs out straight ahead and the feet (shoes off) placed with the soles flat against a box, shoulder-width apart. The patient is then told to reach forward as far as possible with open hands and palms facing downwards (Fig. 2). The distance between the middle finger on the right hand of the patient and the box was measured in centimeters. The test was repeated three times, and the average of the scores was recorded for analysis [15].
Biering-Sorenson test.
In the evaluation of the isometric endurance of the trunk extensor muscles, the Biering-Sorenson test was applied. This is a reliable test for subjects with and without non-specific low back pain [16]. The patients were asked to lie prone on the examination table in with the upper edge of the iliac crests aligned with the edge of the positioning pillow (Fig. 3). The lower body was fixed by the physiotherapist, and the patient was then requested to isometrically maintain the upper body in a horizontal position with the arms folded across the chest. The time was recorded for which the patient was able to maintain the upper body straight and horizontal.

Discussion
The results of this study indicated that a greater improvement was obtained in pain, functionality, lumbar mobility and muscle endurance with the application of Kinesio
All the patients in this study received an exercise program under the supervision of a physiotherapist with the physical therapy modalities beginning from the 6th treatment session. The most commonly used physical therapy modalities in chronic low back pain are therapeutic ultrasound, hot pack, and TENS. In different studies, these methods have been indicated to be effective especially in decreasing pain and improving functionality [6, 7, 8, 9]. Exercise treatments have also been proven to be efficient in chronic low back pain treatment, and they are also widely used [9, 17, 18]. Previous studies have reported that effective improvements were obtained in muscle strength, flexibility, pain, and functionality with the application of physical therapy modalities with exercise treatment [7, 9, 19].
In the current study, in addition to the same physical therapy modalities and exercise treatment applied to the three groups, KT was applied to Group 1 by a qualified physiotherapist at each treatment session, and placebo taping was applied to Group 2 to eliminate the psychological effects of taping. Group 3 was considered as the control group, and no taping was applied to this group. It is thought that KT improves muscle function, increases the circulation and thus decreases pain, edema, and inflammation provides reduced pain by stimulating mechanoreceptors, proprioception, and improves joint function, movement, and stabilization [12, 13]. However, there are few studies which have examined the efficiency of KT. In a study conducted with MRI analysis, it was indicated that KT also mechanically affected tissues far from the target, in addition to the targeted subcutaneous connective and muscle tissues [20]. In a study applied with EMG, it was shown that lumbar muscle function returned to normal in a short time in 28% of the patients with chronic low back pain who had KT, and this effect continued during the 4-week follow-up period [21].
In studies of the treatment of low back pain, few have investigated KT application alone or together with exercise and physical therapy modalities. In those studies, the primarily evaluated measurement was the pain score of patients. In many of the studies, KT alone [22, 23, 24], and KT
In studies by Kelle et al. [22] and Castro-Sánchez et al. [23], the application of KT only was seen to significantly decrease pain and disability in low back pain compared to the control [22] and sham taping [23] groups. These studies are important in terms of showing that KT is also effective when applied alone. In the current study, the absence of a KT only group could be considered a limitation, although the placebo tape group and the conventional treatment only group can be considered as superior aspects of this study.
There is not yet a full understanding of the exact mechanisms underlying the effect of Kinesio
Other hypotheses of pain relief achieved through Kinesio
It has been stated in literature that Kinesio
In previous studies, it has been reported that KT increases the flexion motion range in healthy individuals [32] and patients with low back pain [23, 24, 25]. In the current study, trunk flexibility was evaluated with the sit and reach test. Although the same exercises were applied to all three groups, a greater degree of trunk flexibility was determined in the KT group (
In contrasting results in the literature, in a study where 48-hour and 7-day taping, placebo, and control groups were evaluated to determine the effect of taping in chronic non-specific low back pain, it was reported that there was no significant difference except in the disability index after 48 hours, and it was concluded that taping was ineffective [34]. Similarly, in two systematic reviews [35, 36] it was suggested that there was no high-level evidence indicating the superiority of Kinesio
These conflicting results in studies might be caused by differences in taping techniques or differences in training and experience of the clinicians applying this technique and the clinical features of the patients at the beginning of the treatment. To be able to show the actual efficiency of KT in cases of chronic low back pain, there is a need for studies evaluating different application techniques and studies showing whether there is any application difference between clinicians or treatment sessions. The patients included in the current study had low back pain for three different reasons, and only those with low back pain ongoing for at least three months were included, although no upper limit was placed on the duration of pain. These points can be considered limitations of this study. The treatment response may be different in pain of different etiology and which has been ongoing for different periods of time. In order to reach a high-level of evidence in terms of the efficiency of Kinesio
