The invention concerns a device (10； 100) to activate, stimulate or reinforce the cervical musculature, the device (10； 100) comprising an inner structure (30； 130) made of rigid material and provided with a base wall (13) which faces a reference surface (S), an outer structure (20； 120) made of soft material, arranged above the inner structure (30； 130) and defining a support surface (22； 122, 123) which is able to receive and support the cervical spine (R) of a patient (P), mainly develops along a pre-established linear direction (X), has a concave profile according to a cut plane (Y) orthogonal to the pre-established linear direction (X), and at least one force transducer (37) coupled to a central portion (12, 38) of the outer structure (20； 120) and/or of the inner structure (30； 130) and suitable to detect the intensity and/or the direction of the force applied to the support surface (22； 122, 123) by the cervical spine (R) of the patient (P).
