Abstract
Background: Most hemiplegic children experience disorders related to lower limbs such as balance. Considering the importance of balance, in order to participate in activities of daily living, it is very important to use modern neuro-rehabilitation methods such as mirror therapy to improve balance. The purpose of the present study was to determine the effectiveness of mirror therapy on the static and dynamic balance of children with hemiplegic CP aged 5 to 12 years.
Methods: This study was conducted as a double-blind, randomized clinical trial on 20 children with spastic hemiplegia aged between 5-12 years old, from June 2021 to August 2022 in Tehran, Iran. Participating children were randomly allocated into test (n=10) and control (n=10) groups. The children in the treatment group underwent 20 treatment sessions during four weeks. Each session consisted of 30 minutes of routine treatment and 15 minutes of mirror therapy for lower limbs. In the control group, sham therapy was performed instead of mirror therapy. The exercises performed in a seated position were: (1) active flexion of hip, knee, and ankle joints, (2) active knee extension plus ankle dorsiflexion, and (3) knee flexion (> 90°). Both groups were measured by the Pediatric Balance Scale to assess static balance and the Timed Up and Go test to assess dynamic balance at entry and the end of the study. SPSS version 26 software was used for statistical analysis.

Results: Examining the results of the evaluations showed that before the treatment, the static and dynamic balance of the two groups did not differ significantly (p> 0/05), but the static and dynamic balance scores of the children in the treatment group after the four weeks mirror therapy period (five days per week) were statistically significant different from the control group (p<0/05).
Conclusion: According to the present study, it seems that mirror therapy as a complementary treatment can have a positive effect on improving balance (static and dynamic) in children with hemiplegic CP.

Abstract
Background: Spinal anesthesia is an effective method for providing analgesia in surgery and a safe alternative to general analgesia; But despite its benefits, in many cases it is not free of side effects, including unwanted cardiovascular events such as hypotension and bradycardia. Ondansetron effectively reduces the incidence of nausea, vomiting, and bradycardia associated with spinal anesthesia Thus, the present study aimed to assess intravenous ondansetron's efficacy in preventing post-spinal hypotension among patients scheduled for lower extremity orthopedic surgery at Peymanieh Hospital in Jahrom, Iran.
Methods: This randomized double-blind clinical trial included 60 patients undergoing lower limb orthopedic surgery at Peymanieh Hospital, Jahrom, Iran, from March 2021 to February 2022. Patients were randomly allocated into two groups: the intervention group (receiving 8 mg intravenous ondansetron) and the control group (receiving distilled water). Systolic and diastolic blood pressure (SBP, DBP) and heart rate (HR) were measured before pre-spinal anesthesia, after spinal anesthesia and then every two minutes for the first ten minutes and at 15, 30, 45, 60 and 90 minutes after surgery. After spinal anesthesia, the patient was asked about pruritus every 10 minutes. Nausea and vomiting during surgery in case of incidence, recording and nausea after spinal anesthesia, the patient was asked every 10 minutes.
Results: The chi-square test indicated no significant differences between the study groups regarding age and sex distribution(P>0.05). Time before anesthesia, immediately after anesthesia, 10 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, and 90 minutes after anesthesia, significant difference between ondansetron and placebo groups from There was no mean SBP and DBP and HR (P <0.05). No significant difference between ondansetron and placebo groups in the incidence of pruritus and nausea and vomiting at different times (p <0.05).
Conclusion: Dose of 8 mg of ondansetron in lower limb orthopedic surgery has no significant effect on hemodynamic symptoms as well as the prevention of postoperative nausea, vomiting and pruritus in these patients. Therefore, to achieve more results regarding the transient effect of this drug, it can be compared with other drugs in the class of HT3-5 receptor antagonists.
