Background: A typical plank exercise (PE) strengthens the core muscles, stabilizes the spinal column, and provides stability around the pelvis and trunk when the trunk is aligned. However, because PE require that the hip joint be kept straight, they can activate the hamstring (HAM). Excessive HAM activation can induce tightness, which may cause low back pain. Therefore, it is necessary to explore PE methods that can minimize HAM activity while maximizing core muscle activity. Design: Cross-sectional study. Methods: This study included 30 healthy adults as subjects. We measured the activity of the HAM and the erector spinae (ES), rectus abdominis (RA), and external oblique (EO) muscles using surface electromyography during three PEs (typical PE, PE with balance pad, and PE with sling). Results: The RA, EO, and ES showed the highest muscular activity during PE with balance pad and the lowest during PE with sling; however, the differences were not significant. The HAM showed lower activity during PE with sling than during the other two PEs; however, these differences were also not significant. Conclusion: Although HAM activation was not significantly difference among PE positions, we should recognize altering activation of core and hamstring muscle according to PE postures.

The patellofemoral pint is formed by the articulation of the patella and femoral condyles in the trochlear groove. The complexity of the patellofemoral pint is magnified by the fact that the tibiofemoral pint works in conjunction with the patellofemoral pint. Additionally, other pints such as the subtalar pint., hip and sacroiliac pints indirectly contribute to the function of the patellofemoral pint. This pint has little bony stability, Soft tissue surrounds the pint to increase stability. The patellofemoral pint increases the mechanical advantage of the quadriceps muscles and resists mechanical loading. In patellofemoral dysfunction, patellofemoral contact pattern is disrupted. leading to excessive compression at the pint. When you treat the patellofemoral dysfunction, you should evaluate anatomic and biomechanic components and find factors of patellofemoral dysfunction. Hamstring tightness. weakness of VMO and tightness of lateral retinaculum lead to flexed knee and abnormal patella tracking and patellofemoral pint reaction force and patellofemoral dysfunction. A through understanding of the anatomy and biomechanics may assist the clinician in the recognition and treatment of patients with patellofemoral pain. Therefore physical therapists should apply modality as well as therapeutic exercise, stretching and strengthening. In this paper, I will discuss the germane anatomical structures and biomechanics of the patellofemoral pint.

Purpose : The purpose of present study is to evaluate the joint angles of legs in the standing posture for six patients with unilateral knee osteoarthritis. Methods : The participants underwent unilateral total knee replacement. A motion analysis was used to measure the joint angles of the hip, knee, and ankle. The measurements were taken before the surgery, one week and two weeks after the surgery. Both sides of the legs were evaluated. Results : This result showed that after a certain healing period, both hip joint angles showed a significant difference while there was no significant difference in the knee and ankle joint angles. After surgery, the angle of ankle dorsiflexion was smaller on the operated side than the opposite side compared to the pre-surgery measurements. Conclusion : After surgery, the asymmetry in a standing position left unchanged due to contracture of the knee joint and tightness in the hamstring muscle. Therefore, when physiotherapists plan an initial exercise programs for TKR patients, it is essential to apply adequate exercises which consider the contracture of the leg joints.

Background : Hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome is a rare, autosomal recessive metabolic disorder which is caused by genetic mutations that disrupt the urea cycle. It is characterized by variable clinical presentation and the age of onset. Patients may present with gait disturbance and progressive paraplegia and muscle tightness in the lower extremities. The use of botulinum toxin in metabolic disease has rarely been discussed. We describe a case of a 14-year-old-boy with HHH syndrome, who presented with a several - month history of gait disturbance and lower extremity weakness. Case presentation : A 14-year old male had a history of recurrent upper respiratory tract infections, occasional vomiting, loss of appetite, and general weakness, all of which started since he was 10 months old. He was diagnosed with HHH syndrome at one year of age. At the age of 14, he was referred for the assessment and treatment of his gait disturbance and aggravated weakness of the lower extremities. Brain MRI, electrodiagnostic study and blood test were performed to exclude any lesions related to neurologic dysfunction. Botulinum toxin type A were injected into muscles of adductor longus, adductor magnus, lateral and medial hamstring, and lateral and medial gastrocnemius muscle heads under needle electromyography guidance to reduce lower limb spasticity. Intensive physical therapy including gait training and stretching exercise of adductor and calf muscles were also provided. After intensive physical therapy and botulinum toxin injection to reduce lower limb spasticity, he was able to ambulate for 20 meters independently without any walking aids. There were no adverse events after the injection. Conclusion : Botulinum toxin injection is a safe and effective therapy for patients with HHH syndrome who suffer from gait disturbance.

전방 슬관절 동통 증후군은 여러 가지 형태의 다양한 원인으로 서서히 양측 슬개-대퇴 관절 내 또는 주위에 동통을 야기하는 증상이다. 원인으로는 하지의 부적절한 생역학, 전체적인 신전 기전의 병변, 슬개-대퇴 관절 병변, 슬개골 자체의 병변 또는 부정정렬, 단단한 연부조직, 약화된 근육 등이며, 전방 슬관절 동통 증후군을 평가하기 위해서는 슬개골 정열의 측정이 필요하고 현재 이학적 검사 및 방사선 검사 등 다양한 방법이 사용되어 진단 및 치료 정도를 평가하는데 사용되고 있다. 치료는 슬관절 전방 통증의 원인에 따라 결정되며, 주로 수술적 치료보다는 약물 치료나 대퇴사두근 근력 강화 운동, 함스트링 스트레칭운동 등이 보편적으로 사용되고 있다. 경부목 또는 내측 경골 스트레스 증후군은 전내측 경골 원위 2/3 부위에서 발생되는 통증을 의미하며, 반복적이고 조화되지 않는 충격이 하퇴부에 가해지는 스포츠를 하는 체육인에게 흔히 발생된다. 문제의 원인을 정확히 파악하여 진단하는 것이 치료에 매우 중요하며, 따라서 원인, 치료, 재활 및 예방까지 여러 이론이 보고되었다. 치료는 통증이 심할 경우 휴식과 함께 얼음찜질을 실시하며, 진통제를 복용하여 통증을 완화시켜 주는 것이 좋으며, 또한 다리 근육을 강화시켜 줄 수 있는 운동을 하며, 적절한 재활과 예방적 처치가 추후 재발을 방지하는 데 도움이 된다.
