Sixty-eight patients with chronic nonspecific low back pain were randomized to telerehabilitation (TLRH) (n=34) or clinic-based rehabilitation (n=34). Both groups received identical exercise progressions (two 30-min sessions/week for 8 weeks) and pain-neuroscience education; TLRH used WhatsApp/video plus weekly follow-ups, while the clinic group trained in person. The primary analytic target was time-by-group interaction for pain during lumbar movements and standardized tests, range of motion (ROM) on rocking-backward and knee-extended tests, double-straight-leg test performance, and kinesiophobia; kinesiophobia was also reassessed at 12 weeks. Overall, the results of the study revealed comparable improvements across most outcomes, with TLRH showing greater reductions in kinesiophobia and pain during the left knee-extended test, while clinic care produced larger ROM gains on the knee-extended test. In short, an 8-week, supervised telerehabilitation program was as effective as clinic-based exercise for key clinical outcomes in chronic low back pain.
