Both spinal manipulation (SM) and Integrated Neuromuscular Inhibition Technique (INIT) have a positive effect in individuals with chronic neck pain (CNP), especially when they are combined with therapeutic exercise (TE). However, it has not been determined which of the above combinations is more effective in patients with CNP.
OBJECTIVE:
To compare the efficacy of two different manual techniques (SM and INIT), when combined with the same TE program in the management of CNP.
METHODS:
Eighty women with CNP, allocated into four groups of 20 persons each. The first group followed a 10-week TE program, the second TE and INIT, the third TE and SM, and the fourth was the control group. The Visual Analogue Scale (VAS) for pain, Neck Disability Index (NDI), Pressure Pain Threshold (PPT) of the neck muscles, neck active Range of Motion (ROM), Maximum Isometric Strength (MIS) of the neck muscles, craniocervical flexion test (CCFT) and SF-36 questionnaire scores were evaluated before, during and after the treatment period, with a six-month follow-up.
RESULTS:
There was between groups differences between the three intervention groups and the control group ( 05), with the positive effects being maintained until the six-month follow-up. However, this improvement occurred earlier in the “TE INIT” and “TE SM” groups than in the “TE” group. Differences between the “TE INIT” and the “TE SM” groups were noticed only in the neck muscles PPT values, in which the “TE INIT” group showed greater improvement. Furthermore, some non-statistically significant indications for further improvement of “TE SM” were noted in the left lateral flexion ROM.
CONCLUSION:
The addition of INIT as well as SM in the same TE program can further increase the beneficial effect of exercise in women with CNP. In most measurements both combinations seem to be equally effective. However, INIT improved more local muscle tenderness, whereas SM aided more in the neck lateral flexion ROM.
