DNS: Face-to-face and Telerehabilitation

This study aims to compare the effects of Dynamic Neuromuscular Stabilization (DNS) exercises delivered face-to-face (YDNS) and via tele-rehabilitation (TDNS) on respiratory function, balance, posture, core endurance, and deep stabilization system performance in healthy adults. A total of 34 participants will be randomly assigned to YDNS or TDNS groups and complete an identical 6-week DNS exercise program (3 sessions per week). Assessments will be conducted at baseline and post-intervention, including pulmonary function, Y-Balance Test, posture analysis, McGill's core stability tests, deep stabilization assessment, and patient satisfaction. All evaluations will be performed face-to-face by certified physiotherapists.

Inclusion Criteria: * Aged between 18 and 35 years. * Not engaged in regular physical activity within the past 6 months. * No history of musculoskeletal disorders or chronic diseases. * Able to participate consistently in the exercise program. For the Tele-DNS (TDNS) group: access to reliable internet and appropriate technical equipment for the duration of the intervention. Exclusion Criteria: * Diagnosis or history of neurological, cardiovascular, respiratory, or metabolic diseases. * History of spinal or extremity surgery. * Pregnancy. * Presence of postural deformities or any orthopedic conditions that may affect balance.
