The test try stopped if your topic could not take care of the lead inside the a lateral reputation (new suspended weight touched the floor), or if perhaps the niche shed more 5° of jaw tuck for more than three moments (measured on the inclinometer). Adopting the NEE take to the niche try requested to remain vulnerable together with his/the girl direct supported for starters minute right after which to stay upwards.

Mathematical data

Investigation were reviewed from the SPSS adaptation 15.0 (IBM Corp., Armonk, Nyc, USA). The Kolgomorov-Smirnov sample was used to research the typical delivery of your own details (p > 0.05). To compare the two organizations (acute/subacute otherwise persistent NP), a keen unpaired t test, a beneficial Mann–Whitney You shot, otherwise an effective chi-square shot are did, according to the nature and you can delivery of the analysis. A first analysis of difference was applied evaluate the fresh groups when it comes to what their age is and you can gender.

Pearson’s correlation coefficient was used to assess the bivariate associations of the variables intensity of pain (VAS), NP and disability (NPDS-I), endurance of the flexor neck muscles (NFME test) and endurance of the extensor neck muscles (NEE test). We considered this statistic, in keeping with the recommendations of Atkinson and Nevill , as follows: fair correlation when inferior to 0.30, moderate when ranging from 0.30 to 0.60 and good when superior to 0.60. The statistical analysis was conducted at a 95% confidence level, and p < 0.05 was considered statistically significant.


Thirty-three sufferers offered to take part in this research. Adopting the a thorough anamnesis, history-bringing, and completing a human anatomy graph, about three of those subjects was basically excluded on the studies: two of them had neck pain instead cervical involvement, and something subject experienced a genetic condition affecting your face and you may neck girdle musculature (FSH Dystrophy). Thirty sufferers have been incorporated, at which 18 (60%) were females and you can a dozen (40%) was indeed male. The latest indicate decades try 43 ± a dozen ages. 16 victims (53.3%) were called off physical therapists, seven sufferers (26,7%) in the shape of notices on the web chatrooms, half a dozen sufferers (20%) came with a recommendation out of medical professionals.

Throughout the 29 victims, the fresh new abilities of your own NEE attempt is an average of 246.7 ± 150 seconds (assortment = 48-661), whereas the fresh new efficiency of NFME sample is actually on average 49.9 ± twenty five.3 mere seconds (range = 11-112). 7 subjects when you look at the NEE test and half a dozen subjects for the NFME had less than 50% of indicate get and simply a couple subjects got more than 100% of your imply score both in evaluation. More the fresh fifty% regarding subjects presented survival rates nearby the suggest viewpoints in both evaluation. The brand new subjects reported a hateful problems VAS score regarding ± and you may a hateful NPDS-I get away from ± .

A significant correlation was found between the results of the two endurance muscle tests (r = 0.52, p = 0.003) and a positive relationship was also found between VAS and NPDS-I (r = 0.55, p = 0.002) in the entire sample. No relevant correlation was found between the endurance tests and pain or disability (all, r 0.21)

Two included people (6.66%) complained of acute pain, 11 (%) of subacute pain, and 17 (%) of chronic pain. Due to the very small number of acute cases, we decided to merge acute and subacute subjects: as a consequence, our further analyses considered two different groups, which we named acute/subacute and chronic. There was no significant difference between these two groups with regard to age, sex, localization or frequency of the symptoms, referred symptoms along their arms or referred symptoms such as headache, migraine, and dizziness (Table 1). Moreover, compared with acute/subacute group, chronic NP group had no statistically significant difference in intensity of NP, although the score of NPDS-I was significantly higher in chronic group (Table 2). Endurance of the neck extensor and neck flexor muscles appeared similar in these two groups. There were no significant differences between the groups in terms of reason to stop the isometric endurance muscle tests (pain, other symptoms, tension, fear, muscular or psychological fatigue). A significant effect of gender on NFME test was revealed [F[step 1,26] = 9.2, p < 0.001], but no effects of age on endurance test were demonstrated.
