  • The Purpose of this study was to determine the effects of sciatic nerve mobilization on pain and lower back muscle strength in female patients in their 40s who have been diagnosed with lumbar radiculopathy. Using a simple blinded method, 20 female patients with neuropathy in the nerve segments between L4-S1 were randomly divided into one group (n=10) that would undergo sciatic nerve mobilization, and another group (n=10) that would perform lower back segment stabilization exercises. The two groups attended 3 sessions per week, with each session taking 30 minutes, for a duration of 4 weeks. In the preliminary examinations, the pain index as well as the isometric muscle strength of the lower back extensor and flexor muscles were measured. After the passing of 4 weeks. The same method of measurement was used for the concluding examinations. Comparison of the pain indices in the two groups revealed that they both experienced a statistically significant decrease, and further inspection revealed that the there was a more substantial difference in the sciatic nerve mobilization group. Results of comparing changes in the Isometric Muscle Strength lower back muscle and bending muscle by group, In comparison between groups, the isometric strength of the lower back extensor showed a more significant difference in the sciatic nerve mobilization group (p <.05). Conclulsion, it can be inferred that application of sciatic nerve mobilization has a positive effect on the pain index and isometric muscle strength of the lower back in female patients with lumbar radiculopathy in their 40s.

  • The present study was performed to compare cranial tibial wedge osteotomy (CTWO) and tibial plateau leveling osteotomy (TPLO) through radiographic evaluation. The experiment was conducted with five cadaver dogs [mean (± SD) weight, 32.9 ± 4.1 kg; mean (± SD) age, 6 ± 2 years; three males and two females] euthanized for reasons unrelated to this study. The cadaver dogs consisted of German Shepherd (n = 3), Belgian Malinois (n = 1), and mixed breed (n = 1). CTWO and TPLO were carried out by the standard surgical method. Radiographic evaluation was performed by comparing several factors, including the flexion and extension angles, the anatomical mechanical axis angle (AMA-angle), tibial length, patellar height measurement using the Labelle-Laurin method, mechanical medial proximal tibial angle (mMPTA), mechanical medial distal tibial angle (mMDTA), and frontal plane alignment (FPA). Both the CTWO and the TPLO groups showed significantly increased flexion angles after surgery. Only the CTWO group had significantly increased extension angle. Although both groups showed significant decreases in the AMA-angle, the mechanical axis moved cranially against the anatomical axis only in the CTWO group. The patellar height was significantly lowered in the CTWO group. No significant differences were found in mMPTA, mMDTA, or FPA. In conclusion, radiographic comparison revealed more changes in CTWO group than in TPLO group.

  • Background: This study was to investigate the effect of non-invasive transcranial direct current stimulation due to hemiplegic patients due to stroke on temporal and spatial gait ability. Design: Randomized sham controlled trial. Methods: For the study method, 42 patients with hemiplegia due to stroke were randomly assigned to 14 patients each, and the general walking group, tDCS walking group, and tDCS (sham) walking group were subjected to 5 times a week, 30 minutes a day, and 6 weeks. In the temporal gait variables of hemiplegic patients due to stroke, the effect of the gait time, gait cycle, single support, double support, swing phase, stance phase, gait speed, cadence were measured. In spatial variables, one step length and one step length were measured. Results: As a result of the study, the EG group significantly increased in the step time, gait velocity, and cadence of the paralysis side in the comparison of temporal walking variables between groups according to the application of tDCS of walking ability in hemiplegic patients due to stroke patients(p<.05). In the change in spatial walking variables between groups according to the application of tDCS, the step length and stride length of the EG group showed a significant increase. Both the comparison of temporal and spatial symmetry walking variables between groups according to tDCS application was not significant(p>.05) Conclusion: As a result, tDCS has an effective effect on the improvement of the gait ability of stroke patients. In particular, it is an effective method of physical therapy that can improve the cadence and speed of gait, which can be combined with the existing gait training to effectively increase the gait of hemiplegia due to stroke patients.

  • Purpose: The purpose of this study is to compare the clinical results between two different methods of hindfoot endoscopy to treat posterior ankle impingement syndrome. Materials and Methods: Between January 2008 and January 2014, 52 patients who underwent hindfoot endoscopy were retrospectively reviewed. Two methods of hindfoot endoscopy were used; Group A was treated according to van Dijk and colleagues' standard twoportal method, and group B was treated via the modified version of the above, using a protection cannula. For clinical comparison, the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, time required to return to activity, and the presence of complications were used. Results: There was no statistically significant difference in the AOFAS scores at the final follow-up, and there was also no statistically significant difference in the times for the scores to return to the preoperative level. There were no permanent neurovascular injuries and wound problems in either group. Conclusion: Use of protection cannula may provide additional safety during hindfoot endoscopy. We could not prove whether protection cannula can provide superior safety for possible neurovascular injury. Considering the possible safety and risk of using additional instrument, the use of this method may be optional.

  • Background: The pain caused by local anesthetic injection can lead to patient anxiety prior to surgery, potentially necessitating sedation or general anesthesia during the excision procedure. In this study, we aim to compare the pain relief efficacy and safety of using a digital automatic anesthetic injector for local anesthesia. Methods: Thirty-three patients undergoing excision of a benign soft tissue tumor under local anesthesia were prospectively enrolled from September 2021 to February 2022. A single-blind, randomized controlled study was conducted. Patients were divided into two groups by randomization: the experimental group with digital automatic anesthetic injector method (I-JECT group) and the control group with conventional injection method. Before surgery, the Amsterdam preoperative anxiety information scale was used to measure the patients' anxiety. After local anesthetic was administered, the Numeric Pain Rating Scale was used to measure the pain. The amount of anesthetic used was divided by the surface area of the lesion was recorded. Results: Seventeen were assigned to the conventional group and 16 to the I-JECT group. The mean Numeric Pain Rating Scale was 1.75 in the I-JECT group and 3.82 in conventional group. The injection pain was lower in the I-JECT group (p< 0.01). The mean Amsterdam preoperative anxiety information scale was 11.00 in the I-JECT group and 9.65 in conventional group. Patient's anxiety did not correlate to injection pain regardless of the method of injection (p= 0.47). The amount of local anesthetic used per 1 cm2 of tumor surface area was 0.74 mL/cm2 in the I-JECT group and 2.31 mL/cm2 in the conventional group. The normalization amount of local anesthetic was less in the I-JECT group (p< 0.01). There was no difference in the incidence of complications. Conclusion: The use of a digital automatic anesthetic injector has shown to reduce pain and the amount of local anesthetics without complication.

  • A simple, approximate method for determining the two-group adjoint flux based on the Borresen's coarse-mesh 1.5 group diffusion theory scheme is proposed. With the principle of the 1.5 group diffusion theory scheme, the method describes the thermal leakage term of the adjoint flux approximately by the geomerical buckling determined from the fast adjoint flux. The accuracy of the adjoint flux is investigated tv the comparison of the adjoint flux constructed from this method with a fine-mesh finite-difference KIDD computations. It is shown that the proposed method can predict the adjoint flux as good as the KIDD results. Possible applications of the present method are then suggested in conjunction with the application of the perturbation theory.
