이 연구의 목적은 여성 노인들을 대상으로 낙상자와 비낙상자 간 보행 시 하지의 국부적 안정성과 근 활동 양상을 후향성 접근을 통해 규명하고자 했다. 이를 위해 보행 시 낙상 경험이 있는 20명과 낙상 경험이 없는 20명이 선정되었다. 트레이드밀 보행 시 3차원 운동 캡쳐 시스템과 무선 근전도 장비를 이용해 운동학적 좌표와 근전도 신호를 수집했다. 운동좌표를 이용해 무릎과 발목 관절의 3차원 각 변위를 산출했으며, 이들의 국부적 안정성을 Lyapunov 지수를 통해 계산했다. 근 활성도는 근전도 신호를 이용해 대퇴직근과 대퇴이두근, 전경골근과 비복근을 살펴봤으며, 또한 이들의 동시 수축 지수를 정량화했다. 연구 결과 무릎 관절의 내·외전 움직임의 국부적 불안정성은 비낙상자 집단이 낙상자 집단보다 컸으며(p<.05), 전경골근의 근활성도는 낙상자 집단이 비낙상자 집단보다 적게 나타났다(p<.05). 또한 비복근과 전경골근의 동시 수축 지수는 낙상자 집단이 비낙상자 집단보다 컸다(p<.05). 그 밖에 낙상자 집단에서 비복근과 전경골근의 동시 수축 지수와 발목 관절의 굴신 움직임에 대한 국부적 안정성과는 유의한 상관관계를 보였다(p<.05). 따라서 보행 시 낙상을 예방하기 위해서는 무릎 관절의 내·외전 움직임에 관여하는 근들을 강화하고, 발목 관절의 굴신에 작용하는 비복근과 전경골근을 균형적으로 강화할 필요가 있다고 판단된다.

Background : The purpose of this study was to investigate on the ankle pain, Range of Motion(ROM) and balance ability with old man have fall down experience used to ankle strengthening exercise for 6 weeks. We introduced ankle strengthening exercise in this study in order to recover the pain, ankle ROM and balance ability. Methods : Twenty-four old mans have fall down experience were included for the study. Among them, twelve old mans(experimental group) were ankle strengthening exercise and physical science methods(H/P, TENS, U/S), another twelve old mans(control group) were treated by physical science methods(H/P, TENS, U/S). Each group made use of Visual Analogue Scale(VAS) to pain and goniometer to ankle ROM and Berg Balance Test(BBS) to balance ability to compare the possible changes of pain, ROM and balance ability in two groups after treatment. Results : In experimental group, pain reduced, ankle ROM has increased in dorsi-flexion, plantar-flexion and balance ability has increased for 6 weeks. In control group, pain reduced, ankle ROM has not changed in dorsi-flextion, plantar-flextion and balance ability has not changed for 6 weeks. Conclusion : According to the results, we concluded that ankle strengthening exercise for 6 weeks is effective for reducing pain and increasing ankle ROM and balance ability. Therefore, we thought the old man have fall dawn experience need ankle strengthening exercise for prevention repeatedly fall down.

Purpose: Peripheral neuropathy accompanied by sensory disturbance, such as limb paralysis and hemiplegia, is mainly caused by acute disseminated encephalomyelitis (ADEM). This case study aimed to determine the effect of ankle strengthening exercises that use proprioceptive neuromuscular facilitation (PNF) on the gait, balance, ankle-control ability, and sit-to-stand ability on a patient with ADEM. Methods: A 10-year-old male with quadriplegia and ankle-control impairment participated in this 4-week training intervention. The patient, diagnosed with ADEM, was treated with ankle strengthening exercises that used PNF. Results: The patient demonstrated improvements in balance, ankle-control ability, sit-to-stand ability, and gait performance. Outcome measures (manual muscle test, modified Ashworth scale, sensory assessment, coordination assessment, Berg balance scale, 5 time sit-to-stand test, and 10 m walk test) were taken before and after the training program. Conclusion: The results of this case suggest that an ankle strengthening exercise that uses PNF can improve the gait, balance, ankle-control ability, and sit-to-stand ability in patients with ADEM. In ADEM, the initial treatment is important, and the use of ankle strengthening exercises with PNF could lead to meaningful results. However, there is limited research due to an insufficient number of cases. In the future, more patients will need to be studied.

Background: Plantar fasciitis is one of the most common conditions of the lower limbs. The present study aimed to compare the effect of hip muscle strengthening exercise and stretching of lower extremity in plantar fasciitis, with regard to pain, navicular drop and foot and ankle functional ability. Methods: A total of 42 patients diagnosed with plantar fasciitis were randomly assigned to the experimental group (n=21) that applied the hip muscle strengthening exercise and the control group(n=21) that applied the general lower limb stretching. The intervention period was 6 weeks. Results: The results of the experiment showed that the exercises for strengthening the hip muscle had significant effects on pain, navicular drop and foot and ankle functional ability In addition, lower extremity stretching showed improvement effects in pain, navicular drop and foot and ankle functional ability, however, the difference between the groups except navicular drop did not reach statistical significance Conclusion: Both interventions tested in this study were confirmed to be effective treatment options for patients with plantar fasciitis.

PURPOSE: In this study, we sought to investigate the effect of conservative ankle strengthening exercise programs using a Bosu® ball or taping, on the hallux valgus angle and the pain of hallux valgus patients in their 20s. METHODS: The hallux valgus angle, balance, and pain after measuring the hallux valgus were measured to select suitable subjects. In the ankle strengthening exercise group (ASG) an ankle strengthening exercise program using a Bosu® ball was performed for two sessions weekly for four weeks and the taping group (TG) was given Kinesiotaping® for two sessions weekly, two days per session, for four weeks. Before and after the experiment, a footprint was used to examine the changes in the hallux valgus angle and the visual analog scale (VAS) was used to measure pain. RESULTS: An evaluation of the post-experiment changes in the hallux valgus angle and pain showed statistically significant improvement in both groups. There was no statistically significant improvement between groups. CONCLUSION: These results show that both ankle strengthening exercises and Kinesiotaping® have a positive effect on the hallux valgus angle and pain.

PURPOSE: This study was conducted to investigate the effect of gluteal muscle strengthening exercises (GMSE) with ankle joint pumping exercises (AJPE) on thigh swelling, gait ability, and pain level in patients who underwent total hip arthroplasty. METHODS: A total of 38 patients who had undergone total hip replacement surgery >1 week prior participated in this study. Participants were randomly assigned to a group that performed only GMSE (CG; n = 19) and a group that performed GMSE and AJPE (EG; n = 19). The CG group performed GMSE for 30 min, and the EG group performed GMSE for 30 min followed by AJPE for 15 min. Exercises were performed five times a week, for a total of 20 times over 4 weeks in both groups. Thigh swelling (thigh size), 10 m walking test (10MWT) and timed up and go test (TUG) results, pain level (visual analogue scale, VAS) scores, Short Form 36 health survey (SF-36), and hip outcome scale (HOS) scores were evaluated before and after the intervention. RESULTS: After 4 weeks of intervention, significant differences were observed in the thigh size, 10MWT, TUG, VAS, SF-36, HOS before and after intervention in both groups (p < . 05). However, only thigh size showed a significant interaction between group and measurement time (p < . 05). CONCLUSION: GMSE combined with AJPE might be effective in improving the gait ability and pain level in patients with total hip arthroplasty, and GMSE may be more effective in improving thigh swelling and gait ability than GMSE without AJPE.
