Page 2: Safety Instructions
Do not touch any injured or morbid skin with the stimulators. • Do not use more than 256 mN if you apply the PinPrick stimulators in the face. • Do not use more than 128 mN during wind-up measurements in the face. - Page 3 3. Set components 7 different PinPrick stimulators for different standardized stimuli • set for light tactile stimuli: • brush: SenseLab™ Brush-05 • cotton bud: Böttger 09.143.9105 • piece of cotton wool (Q-tip) attached to an elastic plastic strip • metronome used as a clock during wind-up measurements: Korg MA-1 •...
- Page 4 4. Instructions for use 4.1. Before the first use Before you use the PinPrick stimulators for the first time you should familiarize yourself with their behaviour. For this purpose carefully take the „64 mN“ stimulator out of the box by handling it approximately in the middle of the guiding tube.

In the upper recording the stimulators of 64 mN and 256 mN have been applied correctly. In the lower recording the 256 mN stimulator generated an unintended impulse since it was applied with too much power.

- Page 7 In that case, the comparability of the measurements will be affected. Place the PinPrick stimulators in a smooth movement onto the respective area of • the skin. Swinging placement can affect the effective force impact.
- Page 8 Wind-up In this test a single stimulus is applied by means of the 256 mN PinPrick stimulator. Then - after a period of 10 seconds – a series of ten identical punctate stimuli with a frequency of 1 Hz is applied in the same skin area.
- Page 9 If you observe any resistance or unusual noise during the application of the • PinPrick stimulators the sliding surface of the weight inside the guiding tube could be contaminated or damaged. In that case another effective weight as desired will act on the skin.
