Comparison of the sonographic features of the Achilles Tendon complex in patients with and without achilles tendinopathy: A case-control study. Physical Therapy in Sport, 35, 122-126. https://doi.org/10.1016/j.ptsp.2018.12.0032152-5250http://hdl.handle.net/11268/7725AIM: The aim of the present study was to evaluate and quantify with ultrasound imaging (USI) the Achilles tendon thickness, cross-sectional area (CSA), Kager's fat pad length and gastrocnemius-soleus pennation angle (PA) between chronic mid-portion Achilles tendinopathy (AT) and healthy subjects. METHODS: A total sample of 143 individuals (age: 41.3 ± 12.0 y; height: 1.74 ± 0.0 m; weight: 75.0 ± 11.4 kg; body mass index, BMI: 24.4 ± 2.6 kg/m2) was recruited and divided in two groups: chronic mid-portion AT group (n = 71) and a healthy group (n = 72). RESULTS: The thickness and CSA at 4 cm and 6 cm from the calcaneus was increased showing statistically significant differences (P < .01) in favor the tendinopathy group. For the gastrocnemius-soleus PA and Kager's fat pad length, significant differences (P < .01) were observed for a decrease in favor of the tendinopathy group. CONCLUSIONS: This study reported an increase of Achilles tendon thickness and CSA at 4 cm and 6 cm from the calcaneus as well as a decrease in gastrocnemius-soleus PA and Kager's fat pad length in patients with chronic mid-portion AT.engjournal article10.1016/j.ptsp.2018.12.003restricted accessUltrasonidos en medicinaMedicina deportivaMedicina deportivaMicroondas
