The Investigators aim to evaluate the effectiveness of dry needling treatment in addition to stretching exercises on cramp duration, cramp intensity, cramp frequency, sleep quality, and sensitivity of myofascial trigger points in patients with nocturnal calf cramp.

Our aim in this study is to evaluate the effectiveness of the combination of stretching exercises and dry needling therapy on cramp duration, cramp intensity, cramp frequency, sleep quality, and algometer measurement in patients with nocturnal calf cramps and whose had myofascial trigger point in the gastrocnemius muscle.
