Investigation of the relationship between soft tissue flexibility and acromiohumeral distance in subacromial pain syndrome

Abstract

Purpose The aim of this study was to investigate the shoulder tightness, and was to investigate the relationship between the shoulder tightness and the acromiohumeral distance (AHD) in patients with subacromial pain syndrome.
Methods: Twenty-two patients with subacromial pain syndrome (12 females, 10 males; mean age: 31.2±8.6 yrs.; BMI: 22.8±2.8 kg/m2) were included in this study. The shoulder range of movement was measured by standard goniometer, scapular dyskinesis by “yes/no” method, posterior capsule tightness by “Horizontal Adduction Test”, and pectoralis minor tightness by “Pectoralis Minor Length Test”. AHD was measured in resting position by a real-time ultrasonography. Statistical analysis was used for comparing the shoulder tightness between the symptomatic and asymptomatic sides using “a paired sample t-test”. Pectoralis minor tightness, posterior capsule tightness and AHD was analyzed using Pearson Correlation Test.
Results: There was a difference between the posterior capsule tightness (p=0.008) and pectoralis minor length (p<0.001) in symptomatic shoulders compared to asymptomatic sides. However, there were no significant relationship between the shoulder tightness and the AHD (p>0.05).
Conclusion: In general, decreased shoulder soft tissue length was found in symptomatic shoulders when compared to asymptomatic sides in patients with subacromial pain syndrome. However, shoulder tightness (both symptomatic and asymptomatic shoulders) was not related to resting AHD measurements. Based on these findings, we think that shoulder tightness does not play an important role in resting AHD measurements, other factors which may cause a subacromial space narrowing should be considered.

Subakromiyal ağrı sendromunda yumuşak doku esnekliği ile akromiyohumeral mesafe arasındaki ilişkinin araştırılması

Abstract

Amaç: Bu çalışmanın amacı, subakromiyal ağrı sendromlu hastalardaki omuz çevresi yumuşak doku esneklik kaybının araştırılması ve akromiyohumeral mesafe (AHM) arasındaki ilişkinin ortaya koyulması idi.
Yöntem: Bu araştırmaya subakromiyal ağrı sendromu tanısı konulan 22 hasta (12 kadın, 10 erkek, ortalama yaş: 31,2±8,6 yıl, ortalama VKİ: 22,8±2,8 kg/m2) dahil edildi. Hastaların eklem hareket açıklıkları standart gonyometre, skapular diskinezi “var/yok yöntemi”, posterior kapsül esnekliği “Horizontal Adduksiyon Testi” ve pectoralis minor esnekliği “Pectoralis Minor Uzunluk Testi” kullanılarak ölçüldü. AHM ölçümleri hastaların istirahat postürlerinde ultrasonografi kullanılarak yapıldı. İstatistiksel analizde, etkilenen ve sağlam omuz arasındaki yumuşak doku esneklik farkı “bağımlı gruplarda t-testi”, yumuşak doku esneklikleri ile AHM arasındaki ilişki Pearson Korelasyon Katsayısı kullanılarak analiz edildi.
Bulgular: Hastaların sağlam omuzları ile kıyaslandığında etkilenen omuzlarında posterior kapsül esnekliği (p=0,008) ve pectoralis minor esnekliği (p<0,001) arasında fark vardı. Ancak hastaların omuz çevresi yumuşak doku esneklikleri ile AHM arasında bir ilişki gözlenmedi (p>0,05).
Sonuç: Genel olarak bakıldığında subakromiyal ağrı sendromlu hastaların etkilenen omuzlarının yumuşak doku esnekliklerinin sağlam tarafa göre azaldığı bulundu. Ancak hem etkilenen hem sağlam taraf pectoralis minor ve posterior kapsül esnekliklerinin istirahat AHM ölçümleri ile ilişkili olmadığı sonucuna varıldı. Bu sonuçlara göre omuz çevresi yumuşak doku esneklik kaybı istirahat AHM değişimleri üzerinde önemli bir rolü olmadığı, subakromiyal sıkışmaya neden olabilecek diğer faktörlerin göz önünde bulundurulması gerektiği düşüncesindeyiz.
