OBJECTIVE: To determine whether there was a statistical difference for manual muscle test ( @entity569 ) findings for cervical muscles in subjects with and without mechanical @entity4048 (MNP), and to use confidence intervals to evaluate the sensitivity and specificity of the @entity569 in this group of subjects. CLINICAL FEATURES: Manual muscle strength tests were conducted on two groups of @entity1 who reported to two outpatient chiropractic clinics. In group 1, 148 @entity1 were evaluated for @entity569 data (50 males and 98 females, average age 37), 127 with "whiplash"-type injuries (average duration 16 weeks) and 21 with non-traumatic @entity4048 (average duration 36 weeks). In group 2, 100 @entity1 were evaluated for comparative @entity569 data (39 males and 61 females, average age 38) with no current MNP or remarkable history of MNP. METHODS: Standardized @entity569 assessments of the strength of the sternocleidomastoid, anterior scalene, upper trapezius, and cervical extensor muscles bilaterally were performed on all subjects in groups 1 and 2. RESULTS: In group 1, 139 of 148 @entity1 reporting @entity4048 also showed positive results in at least one of four @entity569 tests (sternocleidomastoid, anterior scalene, upper trapezius, and cervical extensors). In group 2, 30 of the 100 @entity1 without MNP showed positive results in one or more of the four @entity569 tests. Confidence intervals were calculated and showed that, in terms of @entity569 findings, there was a significant difference between the two groups of @entity1 . CONCLUSIONS: A symptomatic group of @entity1 with MNP demonstrated significantly increased @entity569 findings in the form of reduced strength levels compared to a control group. This evidence suggests that the @entity569 is potentially a sensitive and specific test for evaluating cervical spine @entity73 in @entity1 with MNP.
