Paravertebral Muscle Mechanical Properties and Spinal Range of Motion in Patients with Acute Neck or Low Back Pain: A Case-Control Study. Diagnostics. 2021 Feb 20;11(2):352http://hdl.handle.net/10668/3989Our aims were to identify potential differences in muscle mechanical properties (MMPs) of cervical and lumbar tissues and in spinal range of motion (ROM) between patients with acute low back pain (LBP) or acute neck pain (NP) and healthy controls, and to identify if ROMs and MMPs are able to identify subjects among the three groups. Clinical variables (pain, disability, fear of movement, kinesiophobia, quality of life), MMPs and ROMs were obtained in 33 subjects with acute LBP, 33 with acute NP, and 33 healthy control subjects. Between-groups differences and explanatory models to discriminate groups depending on MMPs and ROMs were calculated. The results showed that cervical tone was higher in patients with acute NP than in controls, while cervical decrement was higher in both spinal pain groups. Patients with acute NP showed reduced cervical flexion when compared to acute LBP and control groups, and also cervical rotation, but just against controls. Furthermore, lumbar flexion was reduced in patients with acute LBP when compared to those with acute NP. Cervical decrement was able to discriminate spinal pain individuals from controls in a multinominal regression (R2: Cox-Snell estimation = 0.533; Nagelkerke estimation = 0.600). Lumbar flexion differentiated patients with acute LBP and controls, whereas cervical flexion differentiated patients with acute NP and controls. This study supports a tendency of the affectation of other spinal regions when only one is affected.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/MyotonometryKinematicsCervical spineLow back painNeck painFenómenos biomecánicosVértebras cervicalesDolor lumbarDolor de cuelloMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Diseases::Nervous System Diseases::Neurologic Manifestations::Pain::Back Pain::Low Back PainMedical Subject Headings::Humanities::Humanities::Philosophy::Life::Quality of LifeMedical Subject Headings::Phenomena and Processes::Physical Phenomena::Physical Processes::Motion::RotationMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Research Design::Control GroupsMedical Subject Headings::Diseases::Nervous System Diseases::Neurologic Manifestations::Pain::Neck PainMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Physical Examination::Range of Motion, ArticularMedical Subject Headings::Anatomy::Musculoskeletal System::MusclesMedical Subject Headings::Psychiatry and Psychology::Behavior and Behavior Mechanisms::Emotions::FearMedical Subject Headings::Chemicals and Drugs::Enzymes and Coenzymes::Enzymes::Hydrolases::Peptide Hydrolases::Metalloproteases::Metalloendopeptidases::Matrix Metalloproteinasesresearch article33672470Acceso abierto10.3390/diagnostics110203522075-4418PMC7923441
