Conclusion : the muscle strength of shoulder girdle is weak in amateur sprinters , indicating that it is one of the principal factors affecting the performance . the extensor muscle strength of shoulder joint is more influencing than the flexor muscle strength 應用要點:文章以專業和業余的短跑運動員為觀察對象,測試了其肩關節各肌群的力矩,結果發現專業運動員無論是肩關節屈肌群還是伸肌群力矩均大于業余運動員,證實了短跑運動員肩帶肌群力量是造成運動員成績差異的主要原因之一。

In order to study the influence of some changes in patellar position and configuration on knee extensor mechanism in sagittal plane after total knee arthroplasty , a two - dimensional model of knee joint in sagittal plane based on crossed - four - bar linkage tibiofemoral joint model is developed , which includes patellofemoral joint model in addition 摘要為研究全膝關節置換術后髕骨部分形位參數的變化對伸膝機構性能的影響,建立了以交叉四連桿股脛關節模型為基礎的、包含髕股關節模型的矢狀面膝關節模型。

The vibration strength training is a new type of strength training which gets more and more concerned by experts at home and abroad for effectively increase targeted muscle strength improve the character of flexor and extensor elevate balance capability base on the requisition of special performance 摘要振動力量訓練是一種新興的力量訓練方法,可根據專項動作的要求有效地增加目標肌肉力量、改善屈伸肌特性、提高平衡能力而受到越來越多的國內外專家關注。

The tibia is a superficial bone that can be easily exposed anteriorly without damaging any important structure except the tendons of the tibialis anterior and extensor hallucis longus muscles , which cross the tibia anteriorly in its lower one fourth 脛骨非常表淺,因此在前側能很容易顯露它,并且除拇趾長伸肌腱和脛前肌腱外,不會損傷任何重要的結構,上述兩結構跨過脛骨下1 / 4的前方。

Fig . 1 - 29 anterior approach to ankle joint . extensor hallucis longus and tibialis anterior tendons , along with neurovascular bundle , are retracted medially . tendons of extensor digitorum longus muscle are retracted laterally 圖1 - 29踝關節前入路。拇趾長伸肌腱和脛骨前肌腱與神經血管束一起向內側牽開,趾長伸肌腱牽向外側。

This study analyses the differences in the relative cross - sectional area ( rcsa ) of several cervical extensor muscles , assessed by magnetic resonance imaging ( mri ) , between patients with chronic tension - type headache ( ctth ) and healthy controls 該研究運用mri評價慢性緊張型頭痛患者和健康對照者頸部伸肌的橫截面積的差異。

Tenosynovitis often happens around hand and wrist , and de quervain ' s disease is due to inflammation of the synovial sheath surrounding extensor pollicis brevis and abductor pollicis longus at the radial stuloid process level 摘要手、腕部是全身最容易發生腱鞘炎之處,其中又以狄魁文氏狹窄性腱鞘炎最常見。

The summation of forces on extensor mechanism should be zero according to equilibrium rules of forces before and after total knee arthroplasty based on constant extensor moment 計算得到髕骨形位參數變化前后與伸膝機構相關的動力學參數,包括股四頭肌力、髕韌帶力及髕股關節接觸壓力的變化。

When the extensor digitorum brevis is used as reverse - flow flap , its entire muscle belly can be used for covering small defect in the distal one - third of the dorsal foot 我們成功利用逆轉式伸趾短肌皮瓣來重建足部遠端三分之一處軟組織缺損的兩個病例,都可以得到良好的覆蓋。

For example , a longitudinal incision on the flexor or extensor surface of a joint may cause a large unsightly scar or even a keloid that may permanently restrict motion 例如在關節屈面或伸面的縱行切口可導致難看的大疤痕甚至疤痕疙瘩,引起永久性關節活動受限。

The second , third , and fourth metatarsophalangeal joints are reached by a dorsolateral incision parallel to the corresponding extensor tendon ( fig . 1 - 25 ) 第二、三、四跖趾關節手術可采用平行于相應的趾伸肌腱的背外側切口(圖1 - 25 ) 。

The forces involved in extensor mechanism : the quadriceps muscle force , tension of patellar tendon and patellofemoral joint reaction force , are computed 結果表明,髕骨適當后傾對增強伸膝機構功能有利。

On examination , there were red - brown papules and plaques on the extensor knees , elbows , and dorsal hands 查體見雙膝、雙肘伸側及雙手背側多發的紅棕色丘疹及色斑。
