Intervention

Behavioral:
• Bluetooth Haptic Device (Experimental Frequency) + Needle Sham only
Participants will have the Bluetooth Haptic Device with experimental Frequency placed on their arm and randomized to a series of 4 different vibration patterns/frequencies. Mechanical pain threshold (MPT) will be measure using custom-made weighted pinprick stimuli as a set of five pinprick mechanical stimulators with fixed stimulus intensities (flat contact area of 0.2mm diameter) with forces of 32, 64, 128, 256, and 512mN. The stimulators will be applied at a rate of 2s on, 2s off in a randomized order on participants' forearms until the first sensation of pain is reached and will then be done in descending order until the sensation of pain disappears. This procedure will be repeated five times of ascending and descending stimuli served as pinprick pain threshold on 1 arm at 4 different frequencies/patterns in the BHD.
• Bluetooth Haptic Device (Control Frequency) + Needle Sham only
Participants will have the Bluetooth Haptic Device with control frequency placed on their arm. They will be randomized to a series of 4 different vibration patterns/frequencies. Mechanical pain threshold (MPT) will be measure using custom-made weighted pinprick stimuli as a set of five pinprick mechanical stimulators with fixed stimulus intensities (flat contact area of 0.2mm diameter) with forces of 32, 64, 128, 256, and 512mN. The stimulators will be applied at a rate of 2s on, 2s off in a randomized order on participants' forearms until the first sensation of pain is reached and will then be done in descending order until the sensation of pain disappears. This procedure will be repeated five times of ascending and descending stimuli served as pinprick pain threshold on 1 arm at 4 different frequencies/patterns in the BHD.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mechanical Pain Threshold	Mechanical Pain Threshold will be measured using custom-made weighted pinprick stimuli as a set of seven pinprick mechanical stimulators with fixed stimulus intensities (flat contact area of 0.2mm diameter) with forces of 8, 16, 32, 64, 128, 256, and 512mN.	immediately after intervention
Secondary	Mechanical pain sensitivity	Mechanical pain sensitivity will be taken immediately following each group of levels tests from 0-10; 0=no pain to 10=worst pain ever experienced.	immediately after intervention
Secondary	Anxiety scores	Anxiety level measured by a numerical rating scale (NRS) from 0-10. Scale ranges from 0-10, with higher scores indicating higher anxiety levels.	immediately after intervention
