About

In this study, the investigators will examine the effect of manual therapy on the thoracic spine and its impact on the muscular strength gain of the thoracic extensors. Treatment with manual therapy, as described by Maitland, consists of a specific mobilization of the thoracic spine in the postero-anterior direction on the transverse and spiny processes of the thoracic vertebrae. To ensure the relevance of the measures, and to better control the occurrence of biases inherent to the practice of manual therapy, the investigators constituted three distinct groups: an intervention group, a control group and a group without intervention. In short, this methodology will allow us to explore in detail the effects of specific spinal mobilization on motor control, while taking into account placebo response elements and natural variations in the results

156 participants in 3 patient groups

Interventional

Experimental group

Description:

This study is of an interventional nature, because the investigators want to objectively assess the impact of specific mobilization on neuromuscular functioning, thanks to surface EMG, before and after a specific mobilization of the spine.

Treatment:

Other: mobilization

control

Sham Comparator group

Description:

This approach will help to determine whether there is spontaneous modulation of neuromuscular activity in the absence of intervention. Thus, the investigators can distinguish the effects of intervention from natural variations in the healthy subject.

Treatment:

Other: no effect

no interventional

No Intervention group

Description:

A control group was also integrated to assess whether a mobilization identified as "no effect" could modulate neuromuscular activity by a placebo effect. This approach will allow to disentangle the real effects of mobilization from those that could result from psychomotor responses
