Knee extensor and flexor muscles are functioning as
essential dynamic stabilizers during activity and a possible strength loss in
these muscle groups considerably resulted in knee joint stability. According to
these findings, it was aimed to examine the effect of the anterior cruciate
ligament rupture (ACL) and medial meniscus tear of two female basketball
players who injured due to excessive lateral rotation of the knee movement
during competition and whether a Cybex protocol could be useful to improve the
muscle strength parameters applied to the participants 16 weeks after following
an ACL reconstruction surgery. An ACL rehabilitation protocol that enables
different contraction patterns was conducted using a Cybex dynamometer (USA),
which is an isokinetic measuring device, 3 times/week throughout 8 and 12 weeks
based on the examination results of the flexion and extension strengths of the
knee joint of participants. Bilateral knee extension-flexion muscle strength
deficit of the participant following two months of testing session (Extension
Baseline:  26 %, 1st Month: 15%, 2nd
month: 5%; Flexion Baseline: 11%, 1st Month: 19 %, 2nd Month: 8 %); and
following three months of rehabilitation session were found (Extension Baseline:
40%, 1st Month:34 %, 2nd Month: 24 %, 3rd Month: 14%; Flexion Baseline: 19%,
1st Month: 9%, 2nd Month: 5%, 3rd Month: 3%), respectively. As a result, it can
be stated that Cybex protocol, which was started 16 weeks after ACL operations,
accelerated the return to sports by decreasing the strength differences between
the extremities of athletes.

Ön Çapraz Bağ ve Medial Menisküs Yırtığının Diz Ekstansiyon ve Fleksiyon İzokinetik Pik Tork Kuvvetine Etkisi ve Cybex Test Protokolü Uygulaması: Vaka Takdimi

Öz

Diz ekstansör ve fleksör
kasların aktivite esnasında önemli dinamik stabilizörler olmalarının yanı sıra
bu kas grubunda kuvvet değerlerinde meydana gelen bir azalma durumunda diz
eklemi stabilitesi önemli derecede azalmaktadır. Bu bulgulardan hareketle, bu
çalışmada basketbol müsabakasında dizin aşırı lateral rotasyon hareketi yönünde
zorlanması sonucu sağ ve sol dizlerinden sakatlanan iki kadın sporcuda ön
çapraz bağ (ACL) ve medial menisküs yırtığının diz ekstansiyon ve fleksiyon
izokinetik pik tork kuvvet değerleri üzerindeki etkisi ve aynı zamanda
ameliyattan 16 hafta sonra kişiye uygulanan düzenli Cybex test protokolünün kas
kuvvet değerleri üzerindeki etkisini incelemek amaçlanmıştır. Çalışmada yer
alan kadın sporcular diz ekleminin bilateral fleksiyon ve ekstansiyon ön test
ölçüm değerlerine göre Cybex izokinetik dinamometre (ABD) kullanılarak 8 hafta
ve 12 hafta olmak üzere haftada 3 gün farklı kasılma türlerini içeren bir ACL
rehabilitasyon protokolüne tabi tutuldu. Cybex testleri sonucunda iki ay
boyunca teste katılan kadın sporcunun sağ ve sol diz ekstansiyon-fleksiyon pik
tork kuvvet farkı değerleri (Ekstansiyon Bazal: % 26, 1. ay: % 15, 2. ay: %5;
Fleksiyon Bazal: % 11, 1. ay: %19, 2. ay: % 8); üç ay boyunca teste katılan
kadın sporcunun sağ ve sol diz ekstansiyon-fleksiyon pik tork kuvvet farkı
değerleri (Ekstansiyon Bazal: % 40, 1. ay: % 34, 2. ay: % 24; 3. ay: % 14;
Fleksiyon Bazal: % 19, 1. ay: %9, 2. ay: % 5, 3. ay: % 3); olarak bulunmuştur.
ACL ameliyatlarından 16 hafta sonra uygulanmaya başlanan Cybex protokolünün
sporcuların ekstremiteler arası kuvvet farklarını azaltarak spora dönüş
sürecini hızlandırdığı ifade edilebilir.
