Purpose: The purpose of this study was to determine the preventive effect of joint mobilization on biphasic pain response induced formalin test. Methods: Sprague-dawley rats(n=30) were ramdomly divided into the control group without intervention, sham control group with application of hand contact without mobilization, joint mobilization group with application of hand contact with mobilization. Joint mobilization of knee procedure involved an grade III extension mobilization basically with anterior-posterior gliding of the tibia on the femur. Formalin injection caused biphasic pain response which is lated for 60 minute. The first phase result from primary afferent sensory fiber, wheareas the second phase has been proposed to central sensitization in the central nervous system. Behavioral analysis was performed by digital camera after 5% formalin subcutaneous injection into the dorsal foot. Results: Pain response of joint mobilization group show significant lower than control gorup and sham control group. Conclusion: This result suggest that pre-application of joint mobilization may be effective intervention to prevent the formalin induced pain.

Background: This double-blind randomized controlled trial (RCT) was conducted to evaluate the pre-emptive analgesia and anti-inflammatory efficacy of piroxicam compared with tramadol in patients undergoing oral surgery. Methods: Seventy-eight patients who required extraction of impacted mandibular third molars were randomized into three treatment groups of 26 patients each: group I received 100 mg of tramadol, group II received 20 mg of piroxicam, and group III received a placebo. Drugs were administered intramuscularly 30 min prior to the extraction procedure. Results: Pain intensity, time to first analgesic administration, total analgesic consumption, facial edema, and trismus were the outcomes of interest. The group receiving 20 mg of piroxicam showed significantly lower pain intensity, increased time to first analgesic, and reduced edema from preoperative to postoperative day seven than those in the tramadol and placebo groups. Conclusion: The findings of this study showed that piroxicam had significant pain relief efficacy after third molar surgery compared with that in tramadol.

Background: This study aimed to evaluate the anti-inflammatory efficacy of preemptive intravenous ibuprofen on inflammatory complications such as edema and trismus in patients undergoing impacted mandibular third molar surgery. Methods: Sixty patients were included and divided into three groups (800 mg IV ibuprofen + 50 mg dexketoprofen, 800 mg IV ibuprofen, and control). In all patients, preoperative hemodynamic values were recorded before the infusions. The operation was started at 15-min post-infusion. Evaluation of edema size on the face and mouth opening (trismus) was conducted in the preoperative period, and at postoperative 48 h and 1 week. Results: No difference was determined among the groups in trismus and edema size in postoperative measurements (P > 0.05). There was a difference between group 2 and group 3 only in measurement value of tragus-corner of the mouth on the postoperative day 2 (P < 0.05). A difference was found between the measurement values of trismus preoperatively and at preoperative day 2, and between postoperative day 2 and 1 week in group 3 based on time (P < 0.05). In group 3, edema on the face on postoperative day 2 increased significantly compared to that in the preoperative period (P < 0.001); in addition, edema increased significantly in groups 1 and 2 in the postoperative period but was less than that in group 3 (P < 0.001). Conclusions: In this study, intravenous ibuprofen was determined to be more effective alone or in combination in alleviating trismus and to better limit the postoperative edema.

Background: Neuropathic pain resulting from diverse causes is a chronic condition for which effective treatment is lacking. The goal of this study was to test whether dexamethasone exerts a preemptive analgesic effect with bupivacaine when injected perineurally in the spared nerve injury model. Methods: Fifty rats were randomly divided into five groups. Group 1 (control) was ligated but received no drugs. Group 2 was perineurally infiltrated (tibial and common peroneal nerves) with 0.4% bupivacaine (0.2 ml) and dexamethasone (0.8 mg) 10 minutes before surgery. Group 3 was infiltrated with 0.4% bupivacaine (0.2 ml) and dexamethasone (0.8 mg) after surgery. Group 4 was infiltrated with normal saline (0.2 ml) and dexamethasone (0.8 mg) 10 minutes before surgery. Group 5 was infiltrated with only 0.4% bupivacaine (0.2 ml) before surgery. Rat paw withdrawal thresholds were measured using the von Frey hair test before surgery as a baseline measurement and on postoperative days 3, 6, 9, 12, 15, 18 and 21. Results: In the group injected preoperatively with dexamethasone and bupivacaine, mechanical allodynia did not develop and mechanical threshold forces were significantly different compared with other groups, especially between postoperative days 3 and 9 (P < 0.05). Conclusions: In conclusion, preoperative infiltration of both dexamethasone and bupivacaine showed a significantly better analgesic effect than did infiltration of bupivacaine or dexamethasone alone in the spared nerve injury model, especially early on after surgery.

Purpose: To evaluate the properties of antibiotic and NSAIDs administration before extract of the impacted mandibular third molar. Materials & Methods: No patient showed any sign of pain, inflammation, or swelling at the time of removal. A group of 50 patients was classified in Group 1(preemptive and oral medication was carried out for 3 days postoperatively, N=23) and Group 2(oral medication was carried out for 3 days postoperatively, N=27) subgroups. Clinical and radiologic factors were recorded for each case, and the rationale for assigning the patients to the groups was strictly random. The surgical technique was the same in all cases, and the follow-up period was 1 week. Parameters that were evaluated were infection, swelling, pain and differences in mouth opening. Results: We could not find any significant difference between the 2 groups regarding the evaluated parameters. Conclusion: The results of our study show that antibiotic and NSAIDs administration before the removal of lower third molars does not contribute to a decrease infection, swelling, pain or increase mouth opening. Therefore antibiotic and NSAIDs administration before the removal of lower third molars is not recommended for routine use.

Purpose: The efficacy of periarticular multimodal drug injection and adductor canal block after a medial opening-wedge high tibial osteotomy was compared in terms of the postoperative pain level. Materials and Methods: From November 2016 to March 2017, 60 patients underwent a medial opening-wedge high tibial osteotomy under spinal anesthesia. Preemptive analgesic medication, intravenous patient controlled anesthesia were used for pain control in all patients. Thirty patients received a periarticular multimodal drug injection (group I), and 30 patients received an adductor canal block (group II). These two groups were compared regarding the postoperative pain level, frequency of additional tramadol injections, total amount of patient-controlled analgesia, and number of times that the patients pushed the patient-controlled analgesia button at each time interval. Results: The visual analogue scale scores over the two-week postoperative period showed no statistical significance. The frequency of additional tramadol hydrochloride injections was similar in the two groups over time. The mean number of times that patients pushed the patient-controlled analgesia button was similar in two groups over time. The total amount of patient-controlled analgesia was similar in the two groups over time. Conclusion: This study shows that intraoperative periarticular multimodal drug injections and adductor canal block may have a similar effect on postoperative pain control in patients who have undergone a medial opening-wedge high tibial osteotomy for unicompartmental osteoarthritis of the knee.

The purpose of this study was to investigated the muscle activity difference of lower extremity by abdominal co-contractive activation. 30 healthy women without pain in the low back and lower extremity were conducted. Muscle activities of lower extremity were measured with the active straight leg raise (ASLR) in 20cm raised from the floor without bending the knee at rest, abdominal drawing-in maneuver (ADIM) and abdominal bracing maneuver (ABM), respectively. Hip adductor longus (HadL), rectus femoris (RF), and biceps femoris (BF) muscle activity in the Abdominal bracing maneuver were statistically significantly higher, also gluteus medius (Gmed) and tibialis anterior (TA) muscle activity in the ADIM were higher. We provide the evidence to the positive effects of individual abdominal co-contractive activation training which can enhance postural stability and lower extremity strengthening with volitional preemptive abdominal contraction.
