Does intraluminal acid induce oesophageal shortening via capsaicin-sensitive neurokinin neurons?
This study suggests that luminal acid activates a reflex pathway involving mast cell degranulation, activation of capsaicin-sensitive afferent neurons and the release of substance P or a related neurokinin, which evokes sustained contraction of the oesophageal LSM. This pathway may be a target for treatment of oesophageal pain syndromes.
A specific pattern of hip ROM was found in professional footballers which appeared to be different from controls. These changes may demonstrate the early stages of hip degeneration to which it has been shown ex-professional players are prone to. Hip joint ROM exercises may be necessary in these players to restore normal movement and prevent the onset of hip osteoarthritis (OA).
