Lower Limb Injury

The cross-cultural adaptation will be performed according to the internationally recommended methodology, using the following guidelines: translation, back-translation; revision by a committee, questionnaire diffusion and data collection and analyzing. The psychometric properties will be evaluated by administering the questionnaire to approximately 300 participants. Reliability will be estimated through stability and homogeneity assessment

The primary objective of the study is to determine the efficacy of blood flow restriction therapy on patients with lower limb extensor injuries by measuring pre and post blood flow restriction therapy strength and muscle mass.

The purpose of this research study is to assess the ease, convenience, and efficacy of walking when using a motor powered ankle foot orthosis (AFO) brace, in adults who have had a lower limb injury.

The purpose of this clinical trial is to understand the effectiveness of femoral nerve block, combined sciatic and femoral nerve block, lumbar plexus block, epidural block, and intravenous analgesia pump in the application of lower limb injury (total knee replacement, knee arthroscopy, patella fracture, femoral shaft fracture) surgery. It will also understand the safety of the drugs liposomal bupivacaine and ropivacaine. The main question it aims to answer is: Does nerve block reduce the number of times participants need to use analgesics postoperatively? The researchers will compare femoral nerve block, combined sciatic and femoral nerve block, lumbar plexus block, epidural block, and intravenous analgesia pump to see which analgesic method has the best postoperative analgesic effect. Participants will: undergo nerve block first, then endotracheal intubation general anesthesia after entering the operating room; record vital signs during surgery, record postoperative analgesic doses, NRS pain scores, patient satisfaction, and postoperative nausea and vomiting.
