ABSTRACT
Purpose@#This study investigated the effects of open kinetic chain (OKC) exercise for the gastrocnemius (GCM) and tibialis anterior (TA) muscles on static and dynamic balance and muscle strength. @*Methods@#We recruited 21 healthy participants, dividing them into 3 groups (GCM, TA, and non-exercise). Each group contains 7 participants. Two exercise groups (GCM and TA) performed OKC exercise with elastic bands twice per week for 4 weeks, while non-exercise group did nothing. We obtained the data for static and dynamic balance and muscle strength before and after the intervention. We used the Kruskal–Wallis test to compare and analyze the pre–post-intervention differences among the groups. @*Results@#For static balance, the stability index of the TA group was the lowest for the dynamic platform (p < 0.05). The dynamic balance of the TA group increased for the anterior and posteromedial directions (p < 0.05). The peak torque increased in the TA group for dorsiflexion (D/F) movement and in the GCM group for plantar flexion movement compared with the other groups, except for the left direction during D/F (p < 0.05). @*Conclusion@#OKC exercises with elastic bands were effective for selectively increasing muscle strength. It is clinically thought that strength training for TA muscles will be effective among the muscles of the ankle.
ABSTRACT
PURPOSE@#Although previous studies on the screw-home movement (SHM) for autopsy specimen and walking of living persons conducted, the possibility of acquiring SHM based on inertial measurement units received little attention. This study aimed to investigate the possibility of measuring SHM for the non-weighted bearing using a micro-electro-mechanical system-based wearable motion capture system (MEMSS).@*METHODS@#MEMSS and camera-based motion analysis systems were used to obtain kinematic data of the knee joint. The knee joint moved from the flexion position to a fully extended position and then back to the start point. The coefficient of multiple correlation and the difference in the range of motion were used to assess the waveform similarity in the movement measured by two measurement systems.@*RESULTS@#The waveform similarity in the sagittal plane was excellent and the in the transverse plane was good. Significant differences were found in the sagittal plane between the two systems (p0.05).@*CONCLUSION@#The SHM during the passive motion without muscle contraction in the non-weighted bearing appeared in the entire range. We thought that the MEMSS could be easily applied to the acquisition of biomechanical data on the knee related to physical therapy.
ABSTRACT
Idiopathic hypertrophic pachymeningitis is a rare inflammatory disorder of the dura mater. Spinal involvement is extremely rare and there are few case reports. We present a 36 year-old female of idiopathic hypertrophic spinal pachymeningitis compressing thoracic spinal cord which showed rapid recurrence.

We report two patients who suffered from hemolytic transfusion reactions due to anti-Jkb antibody: one showed acute- and the other showed delayed-type hemolysis. The first patient was a 40-year-old man who suffered from epilepsy after the operation for arteriovenous malformation 16 years ago. He received five units of red blood cells (RBC) after right temporal lobectomy. On the fifteenth postoperative day, fever and chill developed during transfusion of one unit of packed RBC, followed by dark urine and oliguria. The polyethylene glycol-Coombs test and enzyme test revealed anti-Jkb antibody which had not been detected on the pretransfusion specimen. The second patient was a 41-year-old man who was admitted for the reoperation of the prosthetic mitral valve. Because hemoglobin was 5.9g/dL at admission, he received five units of packed RBCs. Oliguria and laboratory findings consistent with hemolytic anemia were observed from the third day of transfusion. Anti-Jkb antibody was detected on antiglobulin phase. Both patients developed acute renal failure (ARF) and hemodialysis with conservative management were done. They finally recovered from ARF without any residual complications. Implementation of more sensitive pretransfusion tests should be considered to prevent rare, but serious hemolytic transfusion reactions.
