Device for the assessment, prevention and treatment of low back pain, which comprises: - a first, a second, a third, a fourth, a fifth and a sixth units (100a, 100b, 100c, 100d, 100e, 100f), each unit comprising: - an EMG acquisition subsystem for measuring the surface electromyography, EMG, signals of a specific muscle group of a patient; - connecting means (10a-20a, 10b-20b, 10c-20c, 10d-20d, 10e-20e, 10f-20f) for connecting the EMG acquisition subsystem to a pair of electrodes attached to the skin of the patient, such that each unit receives the surface electromyography, EMG, signals of a specific muscle group of the patient; and, - at least one actuator for providing haptic stimulus to said muscle group of the patient; - at least one muscular activity pattern recognition and feedback subsystem (200, 500) for: - capturing, amplifying, filtering and sending said surface EMG signals; - extracting certain features of said surface EMG signals; - interpreting said surface EMG signals and determining a muscular activity pattern based on the extracted features; - deciding whether a correction of the muscular activity pattern is needed; and, - if correction is needed, activating the actuators; wherein the device further comprises: - a wearable garment (300, 301, 302) comprising: - a central portion to which the second and fifth units (100b, 100e) are attached parallel to each other;
