이 연구의 목적은 월경주기에 따른 동통역치와 미각역치의 변화를 평가하고자 하는 것이다. 안면부에 동통성 질환이 없고 정상 월경 주기를 가진 건강한 20대 여성 11명이 이 연구에 참여하였다. 2회의 연속적인 월경주기 동안, 월경기(menstrual phase), 여포기(follicular phase), 황체기(luteal phase)의 세 시기에서 압력통각역치, 전기미각역치, NaCl 미각역치를 각각 측정하였다. 각 역치를 월경주기의 시기별로 비교 분석하여 다음과 같은 결과를 얻었다. 압력통각역치와 전기미각역치는 월경주기의 시기에 따라 유의한 차이를 나타내었고, 황체기에서 월경기에서와 비교하여 통계적으로 유의하게 높은 역치를 나타내었다. NaCl 미각역치는 월경주기에서 통계적으로 유의한 변화를 나타내지 않았다.

표준청각검사와 자기청력검사는 청력역치의 측정으로 난청의 종류를 구별하고 누가현상유무를 판정하며, 사청검사를 할 수 있는 공통점을 갖고 있다. 그러나 표준청력검사는 동일강도의 음을 부여하는 대신 자기청력검사는 음의 증강 및 감약이 계속되는 음을 부여하는 점이 양자의 상이점이다. 이런 차이로 인해 자기청력검사에는 일과성 역치 상승(temporary threshold shift)현상이 일어나 청력 역치가 높을 수 있다. 양자의 역치차가 각 청력군별로 어느 정도차이가 있는가를 관찰할 목적으로 정상청력군 50명 (100이), 전음성 난청군 41명(50이), 감각신경성 난청군 38명(50이)을 대상으로 표준 및 자기청력검사의 기도측정을 실시하여 양 검사의 차를 구하고 그 결과를 다음과 같이 요약하였다. 1) 정상청력군과 전음성 및 감각신경성 난청군 모두 자기역치가 표준역치 보다 높게 측정되는 경향으로 난청군에서 더욱 높게 측정되었다. 그러나 자기역치가 낮은 예도 많았다. 2) 양 검사의 일치범위를 $\pm$10㏈로 하면 정상 청력군은 94%, 전음성 난청군 85%, 감각신경성 난청군 79%에서 양 검사가 일치하였다. 3) 자기역치에서 표준역치를 추정할 수 있는 범위는 정상군에서는 5~-l0 ㏈, 난청군에서는 5~-15 ㏈ 의 변동폭이었다. 4) 양 검사의 역치차가 $\pm$20 ㏈이상인 예도 많아 양 검사는 서로 독립된 검사라고 생각되었다.

The aims of this study were to investigate the relationships among several types of thermal pain thresholds, and pressure pain thresholds. This study was designed to examine whether there were associations among different types of pain thresholds, and among different recording sites for each pain threshold measurement. Pain sensitivity thresholds including cold pain threshold (CPT), heat pain threshold (HPT), heat pain tolerance threshold (PTT), and pressure pain threshold (PPT) of 56 subjects with symptoms of temporomandibular disorders were measured on temporal muscle, masseter muscle, TMJ, and tibial areas. Thermal pain thresholds including CPT, HPT, and PTT did not show any gender differences. However, women showed significantly lower PPTs than men on all recording sites. Three thermal pain thresholds including CPT, HPT, and PTT showed weak to high correlations on all the recording sites (r= 0.324 to 0.754, p<0.05). PPTs did not show any significant correlations between each thermal pain threshold. The pain threshold of each recording site showed weak to high correlations in all pain threshold measures (r= 0.284 to 0.878, p<0.05). Our study demonstrated that thermal pain thresholds, and pain tolerance thresholds were significantly correlated, but did not show any correlation between thermal pain thresholds and pressure pain thresholds. There were relatively high correlations among the pain thresholds of different recording sites.

The purpose of this study was to identify whether cutaneous sensory (CS) changes induced by mechanical intervention(MI) increases the trigger point threshold and muscle tone of the same spinal segment to neck disc patients. Thirty persons with Neck disc patients were recruited in this experiment. The subjects consisted of 10 men and 20 women. The mechanical stimulus group induced CS changes for 5 minutes using the Graston instrument and the control group received no action. The CS changes were estimated by using the Von Frey Filament, PPT changes were measured by using the pressure threshold meter and msucle tone changes were measured by using Myotone pro. CS threshold increased significantly when MI was applied (p<0.05). On the same spinal segment, increases in the right infraspinatus PPT and muscle tone was observed (p<0.05) and decreases in the right trapezius PPT was observed(p<0.05). However, the PPT and muscle tone changes in other muscles were not significantly different. Furthermore, the control group CS, PPT and muscle tone were not significantly different. As a result, CS changes induced by MI make to change PPT and muscle tone on the same spinal segment. Therefore, application of MI to the same spinal segment may be of clinical significance as a new rehabilitation method for increasing pain threshold, muscle tone and pain control in neck disc patients.

This study is conducted to provide basic data through the Quantitative Sensory Testing(QST) about edema of the upper extremity with hemiplegia for subacute and chronic patients in management and treatment. For the purposes of the study group I, subacute stroke patients(n = 15) and group II, chronic stroke patients(n = 17), was targeted, it was performed difference between the unaffected side and affected side of the upper extremity volume, MPT, CST, WST, CPT, WPT and QST of VST. As the results, all measurement items showed significant differences when comparing each group of all(p<.001), group I and group II of patients affected side, there was a significant difference in the measurements, with the exception of items MPT sensory test(p<.05). In subacute than chronic numbness due to increased sensory threshold appears in the upper extremity edema was able to confirm. It was focused on the difference in sensory properties according to the edema of stroke patients through quantitative test.

Speech reception threshold is a base for word discrimination testing, but it also serves as a check for the reliability of pure tone audiogram. In order to investigate the correlation between SRT and PTA these tests were carried out in patients with conductive hearing loss and normal hearing, using Grason-Stadler 1702 Audiometer. The results were as follows; 1) The difference between the scores of SRT and PTA's was 2.4 dB with a range of -3.3 dB∼+8.3 dB in conductive hearing loss, and was 1.9 dB with a range of -6.7 dB∼+5 dB in normal hearing group. 2) The difference between the scores of SRT and each speech frequency of PTA was 6 dB at 500 Hz, 3 dB at 1,000 Hz and 8.8 dB at 2,000 Hz in conductive hearing loss, and 3 dB at 500Hz, 2 dB at 1,000Hz, and 5dB at 2,000Hz in normal hearing group.

Background : There are many suggested methods for the indirect determination of anaerobic threshold(AT) using the changes of ventilatory parameters in response to ventilatory load accompanying the increase of blood lactic acid level during exercise and the threshold derived from them is called ventilatory threshold(VT). They include ventilatory equivalent method(VEM), End-tidal $PO_2$ method($PETO_2$). V-slope method(VSM), and respiratory quotient method(RQ). But in the patients with chronic airway obstruction(CAO), the AT determined by ventilatory methods may not reflect true AT because the patients with CAO show inadequate ventilatory response to the increase of blood lactic acid level during excercise. Methods : For the investigation of detection rate and reliability of above four VT determination methods in the patients with CAO, we performed the symptom-limited and maximal incremental exercise test in 17 patients with CAO and 12 normal controls. The incremental workload was 10 W /min in CAO group and 25 W/min in control group. The reliability of VT in each group was investigated by the calculation of Spearman correlation coefficient. Results : The detection rates of VT were 100% by RQ, 91.7% by both VEM and $POETO_2$, and 83.3% by VSM in normal control group, while 94.1% by RQ, 64.7% by VEM and $PETO_2$, and 83.3% by VSM in CAO group. Good correlations were noted among VEM, $POETO_2$, and VSM except RQ in normal control group. But there was no significant correlation except between VEM and $PETO_2$ in CAO group. Conclusions : RQ is very sensitive but crude and VEM is near similar to $PETO_2$. The clinical usefulness of VT determined by ventilatory method might be limited in patients with severe CAO.
