The exam is actually prevented whether your topic couldn’t take care of the head inside a horizontal position (this new suspended lbs moved a floor), or if perhaps the subject forgotten over 5° off chin tuck for over three seconds (measured on the inclinometer). Adopting the NEE sample the topic was questioned to stay prone together with his/this lady direct supported for just one second following to stay upwards.

Analytical analysis

Analysis was basically assessed because of the SPSS variation 15.0 (IBM Corp., Armonk, Nyc, USA). The fresh Kolgomorov-Smirnov shot was applied to analyze the standard shipping of your variables (p > 0.05). Examine the 2 communities (acute/subacute or persistent NP), an enthusiastic unpaired t test, an effective Mann–Whitney U try, otherwise a good chi-rectangular sample was did, according to character and you can distribution of your own investigation. An initial studies out of variance was applied examine the new organizations with respect to how old they are and 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 subjects agreed to take part in this study. Following the an extensive anamnesis, history-providing, and you can filling in a body chart, three of those subjects was indeed omitted on the analysis: a couple of him or her had shoulder discomfort instead of cervical involvement, plus one subject endured a genetic state impacting the face and you will shoulder girdle musculature (FSH Dystrophy). 30 sufferers was indeed integrated, where 18 (60%) was indeed girls and you may a dozen (40%) was basically men. The brand new imply many years try 43 ± 12 decades. 16 subjects (53.3%) was indeed introduced regarding physical therapists, eight victims (twenty six,7%) in the form of notices on the internet chat rooms, half a dozen sufferers (20%) was included with a suggestion of doctors.

In the 29 subjects, new results of your NEE shot are normally ± 150 moments (diversity = 48-661), while new performance of your own NFME sample is actually normally 44.nine ± twenty five.step 3 mere seconds (variety = 11-112). Eight sufferers for the NEE make sure half dozen subjects into the NFME had below fifty% of mean score and only one or two sufferers got more than 100% of your imply get in evaluating. Over the fresh new 50% of victims showed emergency prices close to the mean thinking in assessment. The new victims stated a mean problems VAS score from ± and you will a mean NPDS-We rating out 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[1,26] = 9.2, p < 0.001], but no effects of age on endurance test were demonstrated.
