견관절 불안정성에 대한 진단은 상세한 병력 청취, 이학적 검사, 이에 따른 각종 방사선학적 검사를 통해 이루어진다. 그러나 이학적 검사는 진단에 결정적인 역할을 하고 있음에도 불구하고 어려움을 느끼는 경우가 많다. 정확한 이학적 검사를 위해서는 충분한 해부학적 지식과 많은 경험을 필요로 하며, 또한 정상적인 전이와 병적인 이완의 정도는 매우 구별하기가 용이하지 않은 경우가 많기 때문이다. 견관절의 정상적인 안정성에 대한 해부학적, 생역학적 이해와 정확한 이학적 검사를 통해 불안정성의 방향과 정도뿐만 아니라 동반 병소까지 정확히 진단되어야 성공적인 수술의 전제 조건이 될 것이다.

Purpose: This study was to investigate the short-term effects of spiral taping (ST) on performance on the star excursion balance test (SEBT) in individuals with unilateral chronic ankle instability (CAI). Methods: This study was single-group pre - post measures experimental design. The subjects with CAI were 39 (range, 20-31 years; male 16, females 23) were enrolled in the study. The discomfort had in unilateral ankle and Cumberland ankle instability score was 19.56 (${\pm}3.29$). Spiral tape (a width of 3 mm) was applied $3{\times}4$ cross shape on medial malleolus, lateral malleolus and dorsal of talocural joint of unstable ankle. SEBT was measured baseline and 30 min later in stable ankle and unstable ankle. Results: SEBT showed significantly improved after applying the ST (p<0.05, ES=0.74) on unstable ankle. In comparison the difference of stable and unstable ankle, between the pretest and posttest were significant differences (p<0.01, ES=1.88). Conclusion: These results indicated that ST improves performance on the SEBT. Therefore, it suggests that ST may be a suitable intervention to dynamic balance in patients with CAI.

Purpose: The aim of this study was to determine the effectiveness of breathing exercises and lumbar segmental exercises on the segmental stability of patients with chronic back pain. Methods: Fifty-nine patients, who suffered from chronic low back pain, were enrolled in this examination. They were divided randomly into three groups: experiment group 1 underwent breathing and segmental stabilization exercises (n=20), experiment group 2 experienced segmental stabilization exercises (n=20), and the control group was given the modality treatment (n=19). The measurements were assessed through an Oswestry disability questionnaire (ODQ), as well as a lumbar segmental instability test (LSIT). Results: The ODQ results for experimental groups 1 and 2 were similar (p<0.05), both before and after six weeks of exercise, but different among the three groups (p>0.05). The differences in segmental instability of each of the three groups were similar (p<0.05), and also similar among the three groups (p<0.05). Conclusion: These findings suggest that lumbar segmental stabilization exercises are efficient in increasing the segmental stability and alleviating pain in patients with chronic back pain. Additional studies on this subject will be needed to improve the clinical applications in the future.

본 연구는 카이로프랙틱 기법 중 누운 자세에서 시술되어지는 S.O.T category II 골반 블록 중재가 골반의 불안정으로 인한 기울어짐을 회복시킴으로써 이에 따른 어깨통증을 줄이고 복근의 지구력을 향상시킬 수 있는지 알아보고자 한 것이다. 이 실험을 위해 엉치엉덩관절의 불안정을 가지고 있으며 허리의 통증이 있는 총 50명의 참여자가 실험군과 대조군에 각 25명씩 무작위 할당되었다. 실험군은 category II 블록 중재를 받았고, 대조군은 거짓블록 중재를 받았으며, 이들 두 집단을 통해 중재 전, 중재 후, 그리고 중재 2주 후에 복근지구력과 어깨통증을 측정하여 그 결과를 반복측정 이원분산분석법으로 분석하였다. 분석결과 S.O.T category II 골반 블록 중재 후 실험집단에서 복근지구력이 유의한 증가를 보였으며 중재가 끝난 2주 후에도 유지 되었다. 또한 어깨통증의 경우에도 실험집단에서 통증의 감소를 보였으며 역시 중재가 끝난 2주 후에도 유의한 감소를 보였다. 이상의 연구 결과를 종합해 볼 때 S.O.T category II 골반 블록 중재는 골반의 안정성을 유도하여 복근지구력을 증진시키고, 어깨통증을 감소시키며 중재 후에도 지속효과가 있는 것으로 나타남으로, 골반의 불안정성이 원인이 되는 어깨통증이나 복근지구력을 회복시킬 수 있는 중재법으로 활용되어질 수 있을 것으로 사료된다.

PURPOSE: This study examined the changes in the kinematic variables during walking on a downhill ramp according to the shoe heel height. METHODS: The subjects were 10 adult women with no history of musculoskeletal disorders who agreed to participate in the study. Data were collected using a motion analysis system (VICON) consisting of six infrared cameras. The slope was 120 cm in width, 200 cm in length, and 15 in inclination. To confirm the change in gait parameters (stride length, gait speed) and lower extremity joint angle according to the heel heights of the shoes, flat, 5 cm, and 10 cm heel shoes were prepared and walked alternately. RESULTS: As a result, both the stride length and walking speed showed significant differences according to the heel height between flat and 10 cm (p<.05). In the sagittal plane, there was no significant difference in the hip joint and knee joint, but a significant difference was observed in all events in the ankle joint on all heel heights (p<.05). In particular, the heel strike and mid stance events showed significant differences among all height conditions (p<.05). No significant difference was observed in any of the joint angle changes in the frontal plane (p>.05). CONCLUSION: As the shoe heel height increased, the instability increased and efforts to secure the stability were made, leading to a shortened stride length, walking speed, and angle of the ankle joint.

Regional evaluations of slope stability by the failure criterion and by environmental geological factors were conducted. The failure criterion is the general conditions for plane failure which consider the geometrical conditions between geological discontinuities and topographical slope planes. The factor focused in this condiction is dip and dip direction. Geostatics, named semivariogram was used for establishing structural domains in slope stability evaluation by the failure criterion. The influential range was calculated to 6 km in the case of dip direction of dominant joint set and 7 km in the case of dip of the same dominant joint set. Then applying this failure criterion to the study area produced a slope stability map using the established domains and slopes generated by TIN module of ARC/INFO GIS. This study considered another regional slope stability analysis. 5 failure-driven factors 9the unstable slope map, geology, engineering soil, groundwater, and lineament density) were selected and used as data coverages for regional slope stability evaluation by geoenvironmental factors. These factors were weighted and overlayed in GIS. From the graph of cumulatave area (%) and instability index, finding critical points classified the instability indices. The most unstable slopes are located in the southern area of Mt. Eorae, Dabul-ri, and the eastern area of Junkok-ri in the first area is plane failure. Also, the expected orientations of failure are 59/338 and 86/090 (dip/dip direction).

Objective: The purpose of this study was to identify the effect of reduced plantar cutaneous sensation on gait kinematics during walking with and without CAI. Method: A total of 20 subjects involved in this study and ten healthy subjects and 10 CAI subjects participated underwent ice-immersion of the plantar aspect of the feet before walking test in this study. The gait kinematics were measured before and after ice-immersion. Results: We observed a before ice-immersion on plantar cutaneous sensation, CAI subject were found to reduced ankle dorsiflexion, knee external rotation, hip adduction, and internal rotation compared to control subject. After ice-immersion, CAI subjects were found to reduce knee external rotation, hip adduction. However, no significant ankle joint kinematics. Conclusion: While walking, gait pattern differences were perceived between groups with and without plantar cutaneous sensation. The results of the study may explain the abductions in the hip angle movements in CAI patients at initial contact compared to healthy subjects in the control group when plantar cutaneous sensation was reduced. A change in proximal joint kinematics may be a conservative strategy to promote normal gait patterns in CAI patients.

PURPOSE: The purpose of this study was to investigate the comparison of balance on Stable Ankle(SA), Instability Ankle(IA) using Cumberland Ankle Instability Tool(CAIT). METHODS: Total 54(SA: 27, IA: 27) subjects were volunteered to participate in the study. SA can be defined CAIT score ${\geq}28$, with no history of injury to ankle. IA can be defined persisting symptoms of giving way and ${\leq}24$ on the CAIT after ankle sprain. the balance measured using Biodex Balance System$^{(R)}$(BBS). BBS instability protocols used static, dynamic balance level less stable(2), moderate stable(4) and level more stable(8). RESULTS: There were significant differences at overall, Anterior-Posterior(AP), Medial-Lateral(ML) of static balance, dynamic balance level 2, 4. The dynamic balance level 8 found significant difference at ML, but not found significant differences at overall, AP. CONCLUSION: We suggest that CAIT is acquired more exact information for IA intervention, as balance measured.
