Purpose: This study was done to assess the effect of changes in forward head posture (FHP), neck mobility and headache clinical parameters on episodic tension-type headache (ETTH) and chronic tension-type headache (CTTH) who did craniocervial exercises. Methods: Twelve CTTH subjects and twelve ETTH subjects were studied. Side-view pictures of subjects were taken in both sitting and standing positions, in order to assess FHP by measuring the craniovertebral angle. Cervical range of motion (CROM) was employed to measure cervical mobility. A headache diary was kept to assess headache intensity, frequency, and duration. All subjects did three types of craniocervical exercise over 8 weeks. Measurements were done at pre-treatment, and at 4 and 8 weeks post-treatment. Results: Forward head posture and headache-related clinical parameters showed a significant improvement after craniocervical exercise (p<0.05). Flexion/extension and left/right rotation of CROM was significantly increased after the intervention (p<0.05), whereas changes in left/right bending did not reach statistical significance. Conclusion: This study indicates that craniocervical exercise may be effective in the management of tension-type headache.

Poor posture of the neck and head long been recognized as a factor contributing to the onset and perpetuation of pain in the head and neck region. The purposes of the study were to evaluate the changes in forward head posture and pressure pain threshold in tension type headache group and control group. Forward head posture were measured to craniovertebral angle and cranial rotation angle. Craniovertebral angle was smaller in tension type headache group(p<0.05), and cranial rotation angle was larger in tension type headache group(p<0.05). Pressure pain threshold was similar between tension type headache group and control group with the exception of right suboccipitalis and left temporalis(p<0.05).

Purpose: This study examined whether or not changes in the static and dynamic balance performance occur during pregnancy. Methods: Fourteen pregnant women and fourteen non-pregnant women volunteered to participate in the study. All subjects were tested for their balance performance on the Chattecx Balance System (Chattanooga Group, Inc., USA) under a two platform condition: stable platform and dynamic platform(forward-backward sliding and tilting). The Chattecx Balance System was measured using the postural sway index, anterior-posterior sway index, and medial-lateral sway index. Results: There was a significant difference in the postural sway index and anterior posterior sway index in the static and dynamic platform condition between the pregnant and non-pregnant women (p<0.05). However, there was no difference in the medial-lateral sway index. Conclusion: The postural sway index and anterior-posterior sway index decreases during pregnancy.

Purpose: This study was to compare the effect of center of pressure(COP) displacement and muscle activation onset during expected and unexpected sudden limb loading in subjects with low back pain and healthy control subjects. Most studies of COP displacement and muscle activation onset on postural task focused on sudden trunk loading or gross limb movements. Investigation of the COP displacement and muscle activation onset during expected and unexpected sudden upper limb loading deserves similar attention. Methods: For this study, 14 subjects with low back pain and 12 healthy control subjects are participated. Force plate and surface EMG measures were used to determine COP displacement and muscle activation onset under expected and unexpected sudden upper limb loading. Results: COP displacement and muscle activation onset under unexpected sudden upper limb loading were similar in subjects with low back pain and healthy control subjects. However, COP displacement and muscle activation onset under expected sudden upper limb loading were shortened in healthy control subject but not among the subjects with low back pain. Conclusion: The results provide evidence for impaired feed-forward control in subjects with low back pain.

Purpose: This study assessed the differences in the forward head posture (FHP), cervical range of motion, and headache clinical parameters in episodic tension-type headache (ETTH) subjects, chronic tension-type headache (CTTH) subjects, and healthy controls (university students). Methods: Fifteen CTTH subjects, 15 ETTH subjects and 15 controls without headache were examined. Side-view images of each group were taken in both the sitting and standing positions, in order to assess the FHP by measuring the craniovertebral angle. The CROM was used to measure the cervical range of motion. A headache diary was kept for 4 weeks to assess the headache intensity, frequency, and duration. Results: The craniovertebral angle was smaller, ie, there was a greater FHP, in the CTTH and ETTH subjects than in the healthy controls in both the sitting and standing positions (p<0.05). The CTTH and ETTH subjects showed a lower cervical range of motion than the healthy controls in the total range of motion as well as in the half-cycles (p<0.05). Conclusion: The increased FHP and decreased cervical range of motion might be a contributing factor in the initiation of tension-type headache.

고유수용성 신경근 촉진법의 통합 패턴이 정적 균형에 미치는지, 여자 대학생 20명을 대상으로 6주간 실험하였다. 고유수용성 통합패턴은 Dietz에 의해 고안된 스프린터와 스케이트 패턴을 이용하였으며, 훈련은 주3회 일 1회 실시하였다. Good Balance system을 이용하여 정상적인 기립자세, 눈을 감고 한발 들고 좌,우 기립자세, 눈을 뜨고 한발 들고 좌,우 기립자세에서 X축 속도, Y축 속도와 속도 모멘트 3항목의 변수를 측정한 결과 눈뜨고 서기자세, 눈감고 서기자세, 눈감고 우측외발서기 자세에서 X, Y 축의 평균속도, 압력중심의 속도 모멘트 영역 모두에서 운동 전ㆍ후 감소하여 통계학적으로 유의하게 감소하였으며, 눈뜨고 좌측외발서기 자세에서는 X축의 평균 속도만 운동 전ㆍ후 감소하여 통계학적으로 감소하였다. 이러한 결과 고유수용성 신경근 촉진법의 통합패턴이 정적 균형 능력에 영향을 미치며, 향후 본 연구의 운동방법을 임상에서 환자에게 적용할 수 있도록 더 쉽고, 다양한 형태의 기술이 포함된 연구가 진행 되어야 할 것으로 사료된다. This study was to investigate the effects of the combined patterns of PNF(proprioceptive neuromuscular facilitation) on the static balance ability by 20 subjects for 6 weeks. The combined patterns of PNF were carried out by Sprinter and Skater suggested by Dietz which were practiced once a day, 3 times a week. This study were measured normal standing, one leg left and one leg right standing when eye open and close on GOOD BALANCE system. These result lead us to the conclusion that mean velocity of X,Y direction, COP velocity moment were showed a statically decrease applying post-exercise on Normal Standing Eye Open(NSEO), Normal Standing Eye Close(NSEC), One Leg Right Standing Eye Close(OLRSEC) and Just velocity of X direction were showed a statically decrease applying post-exercise on One Leg Right Standing Eye Close(OLRSEC). The above results from this study indicated that combined patterns of PNF have improved the static balance ability. However the used self-exercise ca be applied to normal people, i.e., the exercise is difficult to apply into clinical patients. The further study should be focused at development of various modified forms of the combined patterns of PNF in keeping up the improvement effect of the exercise.

Prostaglandins are generated through two isoforms of the enzyme cyclooxygenase, constitutively expressed cyclooxygenase(COX)-1 and COX-2, which is induced at sites of inflammation. Inhibition of COX-2 is desirable as this may avoid side effects seen with NSAIDs. We examined the effects of transcutaneous electrical nerve stimulation and cold therapy on the levels of muscle cycloooxygenase-2 mRNA in rats of carrageenan-induced inflammatory. The method of behavioral assessment were paw withdrawal latency(PWL) and tail flick test(TFT). The COX-2 mRNA levels were quantified by reverse transcription-polymerase chain reaction (RT-PCR). Following the transcutaneous electrical nerve stimulation and cold therapy, PWL and TFT were increased and COX-2 mRNA expression in gastrocnemius muscles were decreased. These results suggest that a transcutaneous electrical nerve stimulation and cold therapy were good therapy for a muscle pain.

Purpose: Electrical stimulation is one of several treatments recommended for RA patients. Electrical stimulation of RA patients, reduces pain, or facilitates joint motion prior to exercises. However, there is still limited evidence on the efficacy of electrical stimulation and thus any conclusions drawn about this method remain controversial. Recently, Microcurrent Electrical Neuromuscular Stimulation (MENS) has received significant attention as a potential method of electrical stimulation. In this study, we investigated the effect of microcurrent treatment in rheumatoid arthritis rat. Methods: Subjects were allocated either to the control group or experimental group, which was subject to microcurrent stimulation. Interleukin-1 expression in the metatarsophlangeal joint and the oedema index in the ankle were used for classification and subsequent evaluation of pathology. Subjects were assessed at 1, 7 and 14 days after inducing rheumatoid arthritis through adjuvant injection. Thirty-six subjects, 18 in each group, were used in this study. Statistical analysis was performed by calculating the differences between the two groups and between each interval assessment. Categorical variables were compared between the two groups with the paired-T test. The one-way ANOVA test was performed to assess changes in ordinal variables. Results: Baseline characteristics were similar in both groups. Statistically significant differences were found between the two groups. The biological marker of pro-inflammatory cytokine and oedema index were decreased in response to this treatment. Conclusion: These data show that treatment of rheumatoid arthritis with a microcurrent stimulation device reduced the oedema index and pro-inflammatory cytokine IL-1.

근육통에 의해 유발된 이차성 통각과민과 척수의 허리팽대부에서의 cyclooxygenase-2 (COX-2)의 발현에 경피신경전기 자극(transcutaneous electrical nerve stimulation, TENS)과 냉치료에 대한 효과를 알아보기 위하여 연구되었다. 흰쥐의 장딴지근에 2% carrageenan을 근육주사하여 근통증 실험모델을 만들었다. 이차성 통각과민을 측정하기 위하여 열에 대한 발움추림잠복기 (paw withdrawal latency, PWL)와 꼬리치기검사 (tail flick latency, TFL)를 조사하였다. 척수의 허리팽대부의 COX-2 발현을 역전사중합연쇄반응 (reverse transcription-polymerase chain reaction, RT-PCR)과 면역조직화학염색법에 의해 조사하였다. 열에 대한 이차성 통각과민은 대조군에 비교하여 경피신경전기자극과 냉치료를 적용한 그룹에서 유의적으로 감소하였다. 척수의 허리팽대부에서 COX-2 mRNA 수준은 대조군에 비교하여 경피신경전기자극과 냉치료를 적용한 그룹에서 감소하였으며 또한, COX-2 면역반응성도 척수의 뒤뿔에서 대조군에 비교하여 경피신경전기자극과 냉치료를 적용한 그룹에서 감소하였다. 이러한 결과들은 경피신경전기자극과 냉치료를 적용한 그룹에서 COX-2 발현의 감소는 근육통에 의해 유발된 이차성 통각과민을 감소시키는데 중요한 요인으로 작용할 가능성이 있음을 시사한다. The purpose of this study was to investigate the effects of transcutaneous electrical nerve stimulation (TENS) and cold therapy on cyclooxygenase-2 (COX-2) expression in lumbar spinal cord and on secondary hyperalgesia produced by muscle pain. Muscle pain was experimentally induced by injection of 2% carrageenan into gastrocnemius muscle of Sprague-Dawley rats. For assessment of secondary hyperalgesia, the rats were tested for paw withdrawal latency (PWL) and tail flick latency (TFL) to heat stimulus. COX-2 expression in lumbar cord was examined using RT-PCR and immunohistochemistry. Secondary hyperalgesia to heat stimulus was significantly reduced in the both TENS- and cold-treatment groups, compared to the control group. The COX-2 mRNA levels were down-regulated in the lumbar spinal cord in the both TENS- and cold-treatment groups. In addition, COX-2 immunoreactivity was decreased in the dorsal horn of the lumbar spinal cord in the both TENS- and cold-treatment groups. These results suggested that decreased COX-2 expression in the lumbar spinal cord of the subjects receiving TENS treatment and cold therapy might be an important factor for reducing secondary hyperalgesia produced by muscle pain.
