Impact of longus colli muscle massage on the strength and endurance of the deep neck flexor muscle of adults.

[Purpose] The purpose of the present study was to examine the effects of longus colli muscle massage on the strength and endurance of the deep neck flexor muscle in adults. [Subjects] A total of 60 subjects were divided into an experimental group of 30 subjects and a control group of 30 subjects. [Methods] The experimental group received massage of the longus colli muscle, which is the deep neck flexor muscle, and the control group received superficial neck muscle massage. The strength and endurance of both the experimental group and the control group were measured before and after the intervention using a pressure biofeedback unit (PBU). [Results] After the experiment, the strength of DNF of the experimental group showed a statistically significant increase, and the endurance of DNF of the experimental group showed an increase in its average value. The independent sample t-test revealed no statistically significant differences in the groups. [Conclusion] Massage of the longus colli muscle, which is the deep neck flexor, was shown to improve its strength and endurance, which are measures of neck stabilization. Therefore, longus colli muscle massage can be performed for patients who cannot perform neck-stabilizing exercises or before performing other neck-stabilizing exercises.
