The exam was also discontinued should your topic wanted to avoid on account of exhaustion otherwise pain

The exam are averted in the event your topic could not maintain the direct during the a lateral status (brand new suspended pounds handled a floor), or if the niche missing over 5° out-of chin tuck for more than around three mere seconds (mentioned toward inclinometer). After the NEE attempt the topic are questioned to stay vulnerable with his/the woman direct served for starters second and then to stay upwards.

Mathematical investigation

Data were reviewed by the SPSS adaptation 15.0 (IBM Corp., Armonk, New york, USA). The fresh Kolgomorov-Smirnov attempt was used to research the standard delivery of the details (p > 0.05). Examine both groups (acute/subacute otherwise persistent NP), an enthusiastic unpaired t decide to try, an effective Mann–Whitney You test, otherwise a beneficial chi-square shot are performed, according to the nature and you will shipments of one’s investigation. A first data out of difference was used evaluate the newest teams regarding how old they are and you may 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-around three subjects provided to participate in this research. Following the an intensive anamnesis, history-providing, and filling in a body graph, three of these victims was in fact omitted throughout the analysis: two of him or her had shoulder aches versus cervical involvement, plus one topic suffered from an inherited disease impacting that person and you will shoulder girdle musculature (FSH Dystrophy). 30 victims had been provided, from which 18 (60%) was indeed females and you will a dozen (40%) was basically men. The fresh suggest age are 43 ± a dozen age. Sixteen victims (53.3%) was indeed referred of actual therapists, eight victims (twenty six,7%) in the shape of observes on line chatrooms, half dozen victims (20%) came with an advice off medical professionals.

In the 31 sufferers, the show of your NEE test is normally 246.7 ± 150 moments (variety = 48-661), while the new results of your NFME sample is typically 44.nine ± twenty-five.step three mere seconds (range = 11-112). Seven victims in NEE ensure that you half a dozen victims in NFME had lower than 50% of your imply score and just two victims had more 100% of suggest rating both in evaluation. More than this new 50% from sufferers displayed survival costs close to the indicate values both in evaluation. This new sufferers claimed a mean aches VAS score away from ± and you will a hateful NPDS-We rating off ± .

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.
