Participants will be randomly assigned to their treatment groups according to the numbers obtained from the table, KT group (00-30), placebo (30-60) and control group or without tape (60-90). The allocation of the subjects will be concealed by using sequentially numbered, sealed and opaque envelopes. On the first day of treatment, the envelope allocated will be opened by participant, Blinding description: Participants will be blinded to the study hypotheses (ie, KT versus Placebo or control). Due to the nature of the interventions it was not be possible to blind the researcher. So, the first researcher will apply the typing method, while the second researcher will be blind as the data evaluator. Data analyzer is also blind who is first researcher. N/A Non Specific Chronic Low Back Pain. Intervention 1: Intervention group: Kinesio taping of the lumbar and abdominal muscles is performed. Intervention 2: Placebo group: Placebo taping is used for the lumbar and abdominal muscles. Intervention 3: Control group: without taping.
