ABSTRACT Purpose. To investigate whether there was a difference in hamstring length

between patients with patellofemoral pain syndrome and healthy asymptomatic control

participants between 18 and 35 years old. Relevance. Short hamstrings may produce

greater patellofemoral joint reaction forces. Only three studies, which had confl icting

results, have measured the hamstring length in this patient group (Smith et al., 1991;

Witvrouw et al., 2000; Piva et al., 2005). Subjects. Two groups were tested, one was

diagnosed with patellofemoral pain syndrome (mean age 27 years, n = 11, six males, fi ve

females) and one was of asymptomatic control participants (mean age 25 years, n = 25,

13 males, 12 females). Methods. Ethical approval was granted by the Local Research

Ethics Committee and a cross-sectional observational study was carried out in a hospital’s

physiotherapy department. Hamstring length was evaluated using the passive knee

extension method and a masked universal goniometer to measure the popliteal

angle. Analysis. An independent t-test was used to evaluate between-group differences.

Results. Mean (standard deviation) values for hamstring length were 145.6 (8.7)° for the

patellofemoral pain patients and 153.7 (10.1)° for the asymptomatic control participants.

The mean (95% confi dence interval) difference between the groups was 8.0 (0.8 to 15.1)°,

and this was statistically signifi cant (p < 0.05). Discussion. Although limited by a small

sample size, these results show that hamstring length is shorter in the patellofemoral

patient group than in the asymptomatic participants. It is unclear whether this is a cause

or an effect of the condition. Further research should study how hamstring length changes

with rehabilitation and its relationships with pain. Copyright © 2008 John Wiley & Sons,

    關聯:肌鍵短會產生較大踝骨關節反應力。病患群中僅三個有矛盾結果的研究測量肌鍵長度,(Smith總長度:1991, Witvrouw總長度2000, Piva總長度2005)。


    方法: 經當地道德研討委員會授與道德認同而後在醫院物理治療部進行交叉觀察研究。肌鍵長度採用被動式膝蓋延伸法及一組萬向量角器測量膝後窩角度作評估。


    結果:踝骨疼痛徵候群病患之肌鍵長度平均(標準偏差)值為145.6 (8.7度)而無症狀健康參試對照者為153.7 (10.1度)。兩組間之平均差異(取95%自信間距)為8.0(0.8至15.1度)以此為統計象徵(p<0.05)。

    討論:雖然限制於小型採樣試驗,此一結果顯示踝骨疼痛徵候群病患肌腱長度短於無症狀健康參試對照者肌腱長度。是一個起因或是病狀的影響則情況不明。進一步的探討會對康復肌腱長度如何變化及其與疼痛之關係作研討。 版權© 2008 為John Wiley & Sons, Ltd.所有。
