Brief summary

This study will investigate the effect of subthreshold stimulation on pain and muscle activity in patients with chronic low neck pain and myofascial trigger points.

Detailed description

The study will include 2 groups. One group will receive subthreshold stimulation and other will not receive any treatment. The measurements will include pain and myscle activity.

Design outcomes

Primary

Measure	Time frame	Description
Electromyographical signals	2 months	We will record the the Trapezius muscle activity of both sides.
Pressure sensitivity using pressure ergometer	2 months	We will measure pain threshold produced from Trapezius muscle

Secondary

Measure	Time frame	Description
Neck pain and disability	2 months	We will record the level of pain and disability in neck using neck pain and disability index. standard instrument for measuring self-rated disability due to neck pain and is used by both clinicians and researchers. Each of the 10 items scores from 0 to 5. The maximum score is 50. The obtained score can be multiplied by two to produce a percentage score
Functional ability	2 months	We will measure the functional ability. The Copenhagen Neck Functional Disability Scale has been developed for those who have neck pain and disabilities due to the pain. The scale includes questions relating to headache, ability to sleep and to concentrate and activities of daily living.
