Fig. 1 The schematic figure of the ME 6000, 16 channel muscle tester. The system consists of measurement cables with preamplifiers located about 15cm from the electrode, measuring unit and electrodes. The myoelectric signal is seen on a computer screen when using Wlan, or it can be transferred by a cable to the computer from the measuring unit for analyses (picture from ME 6000 manual).

Fig. 2 Examples of the RMS SEMG recordings of paraspinal neck muscles at C4–C5 level. The upper curve demonstrates the EMG curve and the lower one that of the inclinometer from (A) a healthy subject and (B) a neck pain patient. As the recording of SEMG took place so near the heart, its electrical signals can be seen especially in the healthy person's SEMG curve. The inclinometer curve shows the poor flexibility of the patient's neck, and it contributed also to her SEMG tracing, which showed an increased static contraction and the minimal signs of flexion relaxation.
