ABSTRACT Background: Patients to be operated will receive anesthesia, one of which is spinal anesthesia. Patients who receive spinal anesthesia are usually transferred to the recovery room to stabilize the condition. Some actions that can increase venous return and normal blood circulation flow, one of which is the action of range of motion exercises (ROM). Purpose: The purpose of this study was to identify the effect of passive range of motion exercises (ROM) on the motor response of the lower extremity in postoperative patients with spinal anesthesia in Rumkitban Sidoarjo. Methods: This study used a Quassy experimental design with a one group pretest-posttest approach. The number of samples were 25 people and collected using incidental sampling techniques. The data obtained were then analyzed using the Wilcoxon test with p ≤ 0.01. Results: As many as 80% of postoperative patients with spinal anesthesia who are given passive range of motion exercises (ROM) can achieve Bromage score 2 in the first 2 hours after surgery. Wilcoxon test results indicate that the p value (0,000). The conclusion of this study is that passive range of motion exercises (ROM) can improve the lower limb motoric response in postoperative patients with spinal anesthesia. Discussion: The main task of nurses in the recovery room is to observe blood pressure, respiratory status, oxygen saturation, and level of consciousness. In addition, nurses must apply passive range of motion exercises to postoperative patients to accelerate the patient's recovery from the effects of anesthesia.
