Objective: The purpose of this study was to investigate the immediate effect of applying self-myofascial release (SMR) to the plantar fascia using a foam roller on hamstring and lumbar spine superficial back line (SBL). Design: Randomized controlled trial. Methods: Thirty-one healthy adults agreed to the method and purpose of the study. Selection and exclusion criteria were screened, and baseline measurements for the Toe Touch test and passive straight leg raise (PSLR) test were obtained. The participants were then randomly assigned to the SMR group or the sham group. After group assignment, the SMR group rolled the surface of the foot from the heel to the metatarsal head using a foam roller for 5 minutes. The sham group received passive mobilization of the ankle joint in the supine position. Afterwards, the Toe Touch test and the passive straight leg-raise test were re-assessed. Results: In the SMR group, the Toe Touch test results showed significant improvement (p<0.05). Left and right PSLR test results showed a significant increase (p<0.05). In the sham group, there was no significant difference between pre and post-test results. The SMR group showed a significant difference in the PSLR test and Toe Touch test compared to the sham group (p<0.05). Conclusions: The results of this study showed that SMR on the plantar fascia was immediately effective for improving the flexibility of the SBL of the lumbar spine and hamstring.

The aims of this study were to investigate the correlation between the electromyographic (EMG) activity of the abductor hallucis (AbdH) and the amount of pressure measured by a pinch gauge (PG), and to compare the EMG activity of AbdH and the pressure measured by the PG during short foot (SF) exercise in subjects with pes planus and in subjects with a neutral foot alignment. Fourteen subjects were recruited for this study (pes planus group=7; neutral foot alignment group=7). A surface EMG was used to collect AbdH activity, and a PG was positioned under the first metatarsophalangeal joint to measure the pressure produced by the first metatarsal head during the SF exercise. The AbdH activity and the pressure measured by the PG showed a positive good correlation (r=.80, p<.05). The EMG activity of the AbdH and the pressure measured by the PG were significantly lower for subjects with pes planus than for subjects with a neutral foot alignment (p<.05). Based on these findings, the PG can be recommended as an effective instrument for evaluating the performance of the AbdH. It may also be beneficial for monitoring how well the SF exercise is performed, and for providing visual feedback to patients with pes planus during SF exercise in a clinical setting.

목적: 족부에 발생한 선천성 축후성 다지증에 자기공명영상 검사를 실시하여 그 결과에 대해 평가하고자 한다. 대상 및 방법: 족부에 발생한 선천성 축후증 다지증 및 다지합지증으로 수술을 시행받은 347예(288명)에 대하여 단순 방사선 사진상에 나타나는 변형이 시작되는 부위에 따라 다섯 개의 군으로 분류하였다(넓은 중족골두, 이분중족, 유합된 복제, 불완전 복제, 완전복제 군). 골화가 이루어지지 않아 단순 방사선 사진상 나타나지 않는 부위에 대하여 자기공명영상 검사를 실시하여 유합 혹은 분리여부를 확인하였다. 또한 단순 방사선 사진상 지골 형성이 되지 않은 것처럼 보이는 부분에 대해서도 자기공명영상 검사를 실시하였다. 결과: 단순 방사선 사진상 골화가 이루어지지 않은 부분에 있어서 자기공명영상 검사를 실시하여 보니 잉여지와 고유지 간 유합 혹은 분리되는 양상이 다양하게 관찰되었다. 또한 지골 형성이 이루어지지 않은 듯 보이는 부분에 대해서도 지골의 상태를 효과적으로 알 수 있게 하였다. 결론: 족부에 발생한 선천성 축후성 다지증에 실시하는 자기공명영상 검사는 단순 방사선 사진에서 확인되지 않는 부분에 대한 정확한 해부학적 상태를 알려줄 수 있는 유용한 장치로 사용될 수 있다.
