Deep tendon reflexes were symmetrical and normal in both upper and lower extremities.
Characteristically, the tendon reflexes are depressed or absent, but increase or return following sustained voluntary contraction of the appropriate muscle (posttetanic potentiation).
With progression, some have vibration and proprioception loss, abnormal saccades, nystagmus, ophthalmoparesis, mild optic atrophy, hypertonia (usually early), hypotonia (later), and decreased deep tendon reflexes.
A retraction spring attached between the foot and the leg maintained tension in the tendon.
In animals, particularly at medium and high velocities, the muscles and the tendons behave like parallel springdashpot systems.
This indicates that terminal steps of tendon-cell differentiation are abnormal.
In cases of supraspinatus tendinitis, localization was achieved by inline ultrasound on the base of the tendon.
Since the tendons get stiffer as they are stretched, they allow finger joints to flex or extend within a limited range.
