In a relaxed subject, slight, slow or maintained stretch of the calf muscles, produced by ankle movement or by pressure on the Achilles tendon, reduces the amplitude of the reflex contraction that can be elicited from these muscles by a standard brief electrical stimulation of sensory fibres in the posterior tibial nerve. A slow stretch applied when the subject is strongly contracting the arm muscles, as in Jendrassik's manoeuvre, results in an increase in electrically induced reflex contraction of calf muscles and often there is also a maintained reflex contraction of these muscles opposing the applied stretch. These results are discussed in relation to the possible roles of outflow from primary and secondary spindle endings in altering motoneurone excitability. [ABSTRACT FROM AUTHOR] |
