“…Right (dx) and left (sin) side erector spinal muscle responses obtained by single stimulation o f left and right Erb's points (first and second traces) and left and right popliteal Jossa (third and fourth traces). Note the normal responses, Calibration: 0.2 mV and 100 ms. Some neural structures do not seem to be involved as the relay stations or links within the pathway of the long-loop antigravity mechanism proposed in the previous study (Ertekin & Ertekin 1981). The cerebellum, vestibular system, and pyramidal and extrapyramidal structures cannot be placed within this long-loop circuit directly but they may have some indirect influence.…”

“…In normal subjects, electromyographic responses were obtained from the lumbar erector spinal muscles in response to unilateral sudden arm abduction or to knee flexion and ankle extension produced by single electrical stimuli applied to the brachial plexus at Erb's point, or to the posterior tibial nerve in the popliteal fossa (Ertekin & Ertekin 1981). No such responses were obtained when lying.…”

In 64 patients with various central and peripheral nervous system disorders, the lumbar erector spinal muscle responses evoked by electrical stimulation of the brachial plexus at Erb's point or of the posterior tibial nerve in the popliteal fossa while standing were recorded. These responses were either absent or delayed in patients with involvement of the posterior columns. The latency of the responses was the same in patients with cerebellar syndromes, Parkinsonism, spastic hemiparesis or vestibular ataxia as in normal subjects. The size of the responses was diminished in patients with cerebellar syndromes and increased in those with Parkinsonism and spastic hemiparesis as compared with normal subjects.

Perturbed upper limb movements cause short-latency postural responses in trunk muscles

Addition of a load to a moving upper limb produces a perturbation of the trunk due to transmission of mechanical forces. This experiment investigated the postural response of the trunk muscles in relation to unexpected limb loading. Subjects performed rapid, bilateral shoulder flexion in response to a stimulus. In one third of trials, an unexpected load was added bilaterally to the upper limbs in the first third of the movement. Trunk muscle electromyography, intra-abdominal pressure and upper limb and trunk motion were measured. A short-latency response of the erector spinae and transversus abdominis muscles occurred approximately 50 ms after the onset of the limb perturbation that resulted from addition of the load early in the movement and was coincident with the onset of the observed perturbation at the trunk. The results provide evidence of initiation of a complex postural response of the trunk muscles that is consistent with mediation by afferent input from a site distant to the lumbar spine, which may include afferents of the upper limb.
