Purpose: To determine whether Myofascial Release (MFR) technique in upper cervical region is more effective than using conventional exercises to improve cervical muscle strength in patients with cervicogenic headache. Design: Randomized Controlled Trial. Setting: An outpatient physical therapy clinic, University of social welfare and rehabilitation science, Iran. Methods:We conducted a prospective, randomized controlled, and single blinded trial on 34 patients with cervicogenic headache, aged 15-75 years, which assigned randomly to exercise group (n=17, mean(SD) age=38(11.31) years) and suboccipital myofascial release group (n=17, mean(SD) age=38.88(9.38) years). Ten treatment sessions, 6 times a week for each group were applied. Outcome measures were isometric cervical muscle strength (flexors, extensors, right and left rotators and lateral flexors) measured by force gauge.Results: Statistical analysis (paired t test) revealed a significant improvement in cervical muscle strength after treatment in the MFR and exercise groups compared with before treatment (P<0.05). Based on ANCOVA results, pretest scores as controlling factor, no significant difference was found between two groups after 10 treatment sessions with regard to all variables (P>0.05) except cervical flexors strength (P=0.021) and cervical left rotators strength (P=0.031). Conclusion:Pain and myofascial stiffness can be an impediment for full muscle interference in contraction and application of suboccipital MFR and common exercises can be effective techniques in restoring cervical muscle strength, especially in cervical rotatory movements.

“…It was assumed that pain-relieving therapy would improve neck function, as several studies have found strength increases following passive treatments. Levoska et al (30) found that heat, massage and stretching 3 times a week for 5 weeks increased maximal isometric neck strength by 14% in lateral flexion and 17% in extension, and the occurrence of neck pain decreased significantly. Jordan et al (31) reported that chiropractic manipulation, massage and manual traction therapy performed twice a week for 6 weeks led to increases of 15% in isometric neck flexion and 24% in neck extension strength.…”

Objective: To study the effect of manual therapy and stretching on neck function in women with chronic neck pain. Methods: A total of 125 women were randomized into 2 groups. Group 1 received manual therapy twice a week for 4 weeks followed by stretching exercises. Group 2 performed stretching 5 times a week for 4 weeks followed by manual therapy. Neck function was assessed by isometric neck strength and mobility measurements, and spontaneous neck pain during the past week and strain-evoked pain during the neck strength trials using a visual analogue scale. Results: Both neck muscle strength (11-14%) and mobility (7-15%) improved similarly in both groups, with the exception of greater passive flexion-extension mobility (p = 0.019) in group 1 at week 4. Pain during the neck strength trials decreased from the baseline to week 4 by 26-35% and to week 12 by 39-61% similarly in both groups. Average neck pain during the past week decreased by 64% and 53% in groups 1 and 2, respectively, during the first 4 weeks, remaining rather stable thereafter. The decreases in neck pain during both the past week and strength trials showed association with the changes in neck strength results (r = 0.20-0.29). Conclusion: Both manual therapy and stretching were effective short-term treatments for reducing both spontaneous and strain-evoked pain in patients with chronic neck pain. It is possible that the decrease in pain reduced inhibition of the motor system and in part improved neck function. However, the changes in neck muscle strength were minor, showing that these treatments alone are not effective in improving muscle strength.

“…Consequently, it may be difficult to compare measurements of fo rce in different points of range within individuals, or at the same point in range between individuals, and compromises the method's potential to be used in the fu ture fo r dynamic through range muscle tests. A similar isometric dynamometry method has also been described (Levoska et al 1992) during which the participant, in the supine position, was asked to press their jaw against the resistance of the dynamometer without raising the back of the head off the supporting surface. This is an instruction that should encourage cranio-cervical flexion, however this was not stipulated by the authors.…”

“…This duration of rest period between maximal contractions has been used in previous studies of neck muscle performance (Silverman et al 1991;Levoska et al 1992;Placzek et al 1999;Strimpakos et al 2004). Each contraction lasted between three to five seconds.…”

“…In the preliminary studies in this thesis the torso of participants was stabilized, as is a common practice in neck dynamometry methods (Levoska et al 1992;Portero and Genries 2003), with soft straps placed over the shoulders to minimise trunk movement. It was obvious on preliminary trials that varying the firmness of the straps altered the participants' mandibles resting pressure on the dynamometer application pad and appeared to substantially alter peak torque during the lMVC tests.…”

established that these CCFD measures were specific to the activity of the CCF muscles compared to the other flexor muscles of the neck, particularly when performed at the low (P < 0.01), and moderate (P < 0.02) intensities of effort.The clinical application of the CCFD measurements in the assessment of ICCF muscle performance was evaluated by investigating their test-retest reliability, their capacity to quantity ICCF muscle impairment, and their capacity to respond to a change in ICCF muscle performance following rehabilitation. Measurements of ICCF muscle strength and endurance were shown to have good reliability (ICC 0.7-0.9) and similar measurement error in participants with and without neck disorders. When CCFD measurements of these groups were compared, the neck pain sufferers were significantly weaker (15.9%), and had significantly less endurance both at low (35% deficit) and moderate (27% deficit) lCCf muscle efforts. This is the fi rst method to have demonstrated ICCF muscle impairment over a range of contraction intensities in persons with neck disorders, and is suggestive of its potential clinical application in the diagnosis of neck muscle impairment.The method has also shown a capacity to monitor changes in ICCF muscle ii ACKNOWLEDGEMENTS
