Although age, gender and functional level may influence the clinical outcomes, pre-treatment level of contracture is the main determinant in improvement in ROM at post-injection.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objectives: This study aims to evaluate the clinical outcomes of children with spastic type cerebral palsy (CP) treated with botulinum toxin type A (BoNT-A) injection for lower limb contracture and the influence of age, gender, functional level and degree of initial contracture on treatment outcomes.

Abstract

Objectives: This study aims to evaluate the clinical outcomes of children with spastic type cerebral palsy (CP) treated with botulinum toxin type A (BoNT-A) injection for lower limb contracture and the influence of age, gender, functional level and degree of initial contracture on treatment outcomes. Patients and methods: Clinical records at pre-BoNT-A injection and post-BoNT-A injections of 153 sessions of a total of 118 consecutive children (67 boys, 51 girls; mean age 5.9±2.6 years; range, 2.5-16 years) were retrospectively evaluated. Degrees of pre- and post-injection contracture were evaluated. Post-injection supplemental casting for 10 days was recorded in all cases. Less than 20° of hip flexion contracture, more than 30° of hip abduction, a negative prone Ely test, less than 50° of popliteal angle and at least 5° of ankle dorsiflexion values at post-injection were accepted as sufficient clinical improvement. Results: Sufficient post-injection range of motion (ROM) was observed in 80% of cases with hip flexion contracture, in 45% of cases with hip adduction contracture, in 84% of cases with knee flexion contracture and in 77% of cases with ankle equinus contracture. Prone Ely test that was positive in 60% of cases with knee extension contracture was negative at post-injection. Improvement in contractures were prominent in children with lesser degree initial contractures. Conclusion: Botulinum toxin type A injection increases ROM in hip, knee and ankle joint contractures in CP. Although age, gender and functional level may influence the clinical outcomes, pre-treatment level of contracture is the main determinant in improvement in ROM at post-injection.

Özet

Amaç: Bu çalışmada alt ekstremite kontraktürü nedeniyle botulinum toksin tip A (BoNT-A) enjeksiyonu ile tedavi edilen spastik tip serebral palsi (SP)’li çocukların klinik sonuçları ve yaşın, cinsiyetin, fonksiyonel düzeyin ve başlangıç kontraktür derecesinin tedavi sonuçlarına etkisi değerlendirildi. Hastalar ve yöntemler: Toplam 118 ardışık çocuğun (67 erkek, 51 kız; ort. yaş 5.9±2.6 yıl; dağılım, 2.5-16 yıl) BoNT-A enjeksiyonu öncesi ve 153 seanslık BoNT-A enjeksiyonu sonrası klinik kayıtları retrospektif olarak değerlendirildi. Enjeksiyon öncesi ve sonrası kontraktür dereceleri değerlendirildi. Tüm olgularda enjeksiyon sonrası 10 günlük tamamlayıcı alçı uygulaması kayıt edildi. Enjeksiyon sonrası 20°’nin altında kalça fleksiyon kontraktürü, 30°’den fazla kalça abdüksiyonu, negatif pron Ely testi, 50°’nin altında popliteal açı ve en az 5° ayak bileği dorsifleksiyon değerleri yeterli klinik düzelme olarak kabul edildi. Bulgular: Kalça fleksiyon kontraktürü olan olguların %80’inde, kalça adduksiyon kontraktürü olan olguların %45’inde, diz fleksiyon kontraktürü olan olguların %84’ünde ve ayak bileği ekin kontraktürü olan olguların %77’sinde enjeksiyon sonrası yeterli eklem hareket açıklığı (EHA) görüldü. Diz ekstansiyon kontraktürü olan olguların %60’ında pozitif olan pron Ely testi enjeksiyon sonrası negatif idi. Başlangıç kontraktür düzeyi daha düşük olan çocuklarda kontraktürde iyileşme belirgin idi. Sonuç: Botulinum toksin tip A enjeksiyonu SP’de kalça, diz ve ayak bileği kontraktürlerinde EHA’yı artırır. Yaş, cinsiyet ve fonksiyonel düzey klinik sonuçları etkileyebilse de enjeksiyon sonrası EHA’daki iyileşme üzerinde temel belirleyici tedavi öncesi kontraktür derecesidir.
