The test are prevented in the event your subject couldn’t take care of the direct when you look at the a horizontal standing (the new suspended pounds moved a floor), or if the subject missing more than 5° from mouth put for over around three moments (counted for the inclinometer). Pursuing the NEE sample the niche is expected to remain susceptible together with/the girl head offered for just one second and then to sit upwards.

Statistical investigation

Investigation was basically analyzed by the SPSS adaptation 15.0 (IBM Corp., Armonk, Ny, USA). The newest Kolgomorov-Smirnov test was applied to analyze the standard delivery of your parameters (p > 0.05). Examine the 2 organizations (acute/subacute otherwise chronic NP), a keen unpaired t take to, a beneficial Mann–Whitney You attempt, otherwise an effective chi-rectangular decide to try is did, with respect to the nature and you can delivery of one’s data. A primary research off difference was utilized examine the latest communities with regards to how old they are and you will sex.

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-about three sufferers wanted to take part in this study. Following an extensive anamnesis, history-delivering, and completing a human anatomy graph, around three of them victims was basically omitted throughout the research: a couple of her or him had shoulder pain rather than cervical wedding, and another topic suffered with a hereditary state impacting your face and you may shoulder girdle musculature (FSH Dystrophy). Thirty sufferers have been included, of which 18 (60%) was basically females and twelve (40%) were male. The brand new mean many years is 43 ± 12 ages. 16 sufferers (53.3%) was basically introduced from actual therapists, seven subjects (26,7%) by means of notices online chat rooms, half a dozen subjects (20%) came with an advice out of doctors.

Regarding 29 victims, the brand new efficiency of NEE take to are typically ± 150 mere seconds (range = 48-661), whereas this new efficiency of your own NFME try is typically forty-two.9 ± twenty-five.3 seconds (range = 11-112). Eight sufferers within the NEE test and half a dozen victims when you look at the NFME had lower than fifty% of suggest rating and just two sufferers got more 100% of your own imply score both in tests. More the fresh new 50% out-of subjects displayed endurance rates nearby the indicate philosophy both in tests. The sufferers said a mean aches VAS rating from ± and you will a hateful NPDS-I rating of ± .

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 < 0.26, p > 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.
