Objectives : In the present study, the effect of electroacupuncture (EA) applied to SI6 and won-rak point on the ankle sprain model was examined. A common source of persistent pain in humans is the lateral ankle sprain. Methods : To model this condition, the rat's right ankle was bent repeatedly, overextending lateral ligaments, for 4 min under enflurane anesthesia. The rat subsequently showed swelling of the ankle and a reduced stepping force of the affected limb for the next several days. The reduced stepping force of the limb was presumably due to a painful ankle. EA was applied to the several acupuncture point on the contralateral forelimb for 30 min under gaseous anesthesia. After the termination of EA, behavioral tests measuring stepping force and Paw volume were Periodically conducted during the next 4 h and 18 h respectively. Results : EA applied to $SI_6$ with won-rak point produced more powerful improvement of stepping force of the sprained foot than to $SI_6$ alone lasting for at least 4 h. However, neigher $KI_4$ point nor $BL_{64}$ point produced any significant increase of weight bearing force. The improvement of stepping pressure was interpreted as an analgesic effect. The analgesic effect was specific to the acupuncture point since the analgesic effort on the ankle sprain pain model could not be mimicked by EA applied to $KI_4$ or $BL_{64}$. In addition, EA applied to $SI_6$ with won-rak combination point showed inhibitory effect on the paw edema induced by ankle sprain. Also, COX-2 protein expression increased by ankle sprain were suppressed by the EA stimulation. Conclusion : These data suggest that EA with won-rak combination point produces a more potent analgesic effect on the ankle sprain pain model in the rat and that EA with won-rak combination point induced anti-inflammatory effect through the suppression of COX-2 protein expression.

Objectives: Pharmacopuncture which is a combination of acupuncture and herbal medicine helps to prevent and treat the diseases and symptoms including various pains. However, little was known about the therapeutic effects and its mechanisms on acute pain, although pharmacopuncture has been used frequently in acupuncture clinics. Acupuncture is known for producing analgesia for persistent ankle sprain pain in human. Furthermore, it also produces analgesia in a rat model of ankle sprain pain. Methods: To illuminate the underlying mechanisms of capsaicin pharmacopuncture-induced analgesia, weight bearing force (WBF) was observed on the acute ankle sprained rat model. Ankle sprain was induced in the rat by manually hyper-extending ligaments of the right ankle. Capsaicin pharmacopuncture was applied to SI6 (Yanglo) on the left forelimb (contralateral to the sprained ankle). Results: In behavioral test, capsaicin pharmacopuncture produced marked analgesic effects on acute ankle sprained animals as measured by WBF of the affected limb similar to manual acupuncture. Capsaicin pharmacopuncture was also suppressed by serotonin (5-HT) receptor antagonist methysergide (2 mg/kg, Lp.), but not by opioids receptor antagonist naltrexone (10 mg/kg, Lp.) and alpha adrenoceptor antagonist phentolamine (5 mg/kg, Lp.). Conclusion: The data suggest that capsaicin pharmacopuncture-induced analgesia is accomplished by activating the descending serotonergic inhibitory systems.

Objectives : The objectives of this study is to compare the effects of electroacupuncture(EA), warm needling(WN) and Radio Frequency warm needling(RFWN) stimulations on the acupoints at the artificially damaged ankles of Sprague-Dawley rats, which could be classified as the Grade 3. Methods : The foot weight bearing force ratio(FWBFR) of ankle sprain was measured first at 24 hours after without any other stimulations. Pain Recovery Index(PRI) represents the analgesic level, and modified Pain Recovery Index(mPRI) shows the accumulated recovery level. PRI was measured at 2 hours after each stimulus on GB34, GB39 and GB42, and mPRI was during 7 days. Results : EA stimulation of GB34 and GB39 acupoint in grade 3 ankle sprain showed a marked analgesic and recovery effect. RFWN of GB42 exhibited significant analgesic and pain recovery effect. RFWN of GB34 resulted in pain recovery effect but not analgesic effects, and RFWN of GB39 resulted in analgesic effect 2 hours after but not pain recovery. However, WN did not affect the pain recovery among three acupoints at all. Conclusions : In the Grade 3 ankle sprain model, the difference of analgesic effects were explained by the acupoints and the stimulation methods according to the accumulated recovery effects during 7 days. It is insufficient to determine that a certain acupoint has a specific analgesic effect depending on the stimulation method by the results of this study. Therefore, the effects of each stimulation on the acupoints in any other meridians at the sprained ankle should be compared and analyzed.

Purpose: To compare the efficacy between cast immobilization and functional treatment using an ankle brace as a treatment for acute lateral ankle sprain. Materials and Methods: This study reviewed the medical records of 157 acute ankle sprain patients who were treated between 2009 and 2014. A total of 101 cases were included in this study except for cases with a combined injury, and could not be followed up for eight weeks after the first visit. The patients were divided according to the treatment modality: a cast immobilization group (64 cases) and functional treatment group (37 cases). The clinical outcomes were assessed retrospectively based on the medical records of each group. The residual symptoms, such as pain, swelling, and instability, at three weeks after the primary treatment and at the last visit were compared. Results: The residual pain and instability were significantly common in the functional treatment group at three weeks. Five cases (7.8%) of pain and one case (1.6%) of instability were in the cast group whereas nine cases (24.3%) of pain and six cases (16.2%) of instability in functional treatment group (p=0.021, p=0.014). On the other hand, there was no meaningful difference at the last follow-up. Residual pain, swelling, and instability at the last visit were noted in three (4.7%), six (9.4%), and four cases (6.3%) in the cast group, and three (8.1%), three (8.1%), and three (8.1%) were observed in the functional treatment group. Six patients refused cast immobilization. Conclusion: Although there was no significant difference at the last follow-up, cast immobilization appears to be more effective than a functional brace in terms of early pain relief and early restoration of ankle stability as a treatment for acute ankle lateral sprain in this study.
