RESUMEN
OBJECTIVES: The aims of this study were twofold: 1) to evaluate the differences in pain sensitivity of patients with greater trochanteric pain syndrome (GTPS) and 2) to examine the association between pain expansion, pain severity, and pain-related central sensitization somatosensory variables in patients with GTPS. STUDY DESIGN: A cross-sectional study. SETTING: Primary health care centers. SUBJECTS: The sample consisted of 49 participants with a mean age of 48.28 ± 8.13 years and included eight males (16.3%) and 41 females (83.7%). METHODS: Conditioned pain modulation (CPM), pain location, temporal summation, pressure pain detection threshold (PPDT), and pain intensity were recorded. Pain severity was determined with the Graded Chronic Pain Scale (GCPS). RESULTS: Several participants (34.7%) showed a negative conditioned pain modulation and a statistically significant negative moderate correlation (P < 0.05; r = -0.316) between conditioned pain modulation and right view percentage of pain location. Temporal summation at the major trochanter showed a statistically significant low negative correlation (P < 0.05; r = -0.298). The GCPS exhibited a statistically significant moderately positive correlation (P < 0.01; r = 0.467) with the PPDT at the trochanter and a significant correlation with the postero-superior iliac spine (P < 0.01; r = 0.515) and epicondyle (P < 0.01; r = 0.566). CONCLUSIONS: Patients with GTPS presented altered CPM, a relationship with more pain areas associated with negative CPM, and a positive association between pain severity and mechanical hyperalgesia at remote sites. Thus, physicians could apply these outcome measurements to assess primary care patients with GTPS and determine the central sensitization presence to prescribe adequate multimodal treatment approaches.

OBJECTIVE: The aim of this study was to relate forearm anthropometric measures to ultrasound pronator teres depth to determine the necessary needle length to prevent median nerve (MN) injury during pronator teres dry needling. METHODS: We conducted a study employing a diagnostic accuracy prediction model (NCT03308279) at a Spanish university center. The study recruited 65 participants to predict the depth of the MN (measured with ultrasound) in the pronator teres using a decision tree algorithm to reduce the risk of MN puncture using 2 needle lengths (13 mm or 25 mm). The decision tree was developed by automatically selecting a cutoff for body mass index, forearm length and circumference, and pronator teres thickness. RESULTS: For forearm circumferences ≤27.5 cm, the predictive value for the 13-mm needle was 92%. For forearm circumferences >27.5 cm and forearm lengths ≤26.75 cm, the predictive value for the 25-mm needle was 100%. CONCLUSION: Based upon the findings of this study, we suggest that needle length should be selected according to forearm anthropometric measures to prevent MN injury during pronator teres dry needling.

We aimed to compare the effects between non-vibration foam rolling (NVFR) and vibration foam rolling (VFR) on visual analogic scale (VAS), pressure pain threshold (PPT), oxygen saturation (SmO2), countermovement jump (CMJ) and hip and knee range of movement (ROM) after eliciting muscle damage through eccentric acute exercise using an inertial flywheel. Thirty-eight healthy volunteers (32 men, 6 women; aged 22.2±3.2 years) were randomly assigned in a counter-balanced fashion to either a VFR or NVFR protocol group. All participants performed a 10x10 (sets x repetitions) eccentric squat protocol to induce muscle damage. The protocols were administered 48-h post-exercise, measuring VAS, PPT, SmO2, CMJ and ROM, before and immediately post-treatment. The treatment technique was repeated on both legs for 1 minute for a total of five sets, with a 30-s rest between sets. The VFR group showed substantially greater improvements (likely to very likely) in the passive VAS (VFR -30.2%, 90% CI -66.2 to -12.8) with chances for lower, similar or greater VAS compared with the NVFR group of 82%, 14% and 4%, respectively and passive extension hip joint ROM (VFR 9.3%, 90% CI 0.2-19.2) with chances for lower, similar or greater ROM compared with the NVFR group of 78%, 21% and 1%, respectively. For intragroup changes, we observed substantial improvements in VAS (p=.05), lateral vastus, rectus femoris and medial vastus PPT. The results suggest that the VFR group achieved greater short-term benefits in pain perception and passive extension hip joint ROM. Both protocols were effective in improving PPT, SmO2, CMJ and knee joint ROM. The enhanced improvement in VAS and hip ROM measures could have significant implications for VFR treatment.

OBJECTIVES: Several authors have evaluated different pain measurements, including quantitative sensory testing (QST), temporal summation (TS), and conditioned pain modulation (CPM) in order to determine the presence of central sensitization (CS) and its influence on patients with temporomandibular disorders (TMD). Since there are no convincing studies about this topic, the purpose of this study was to conduct a review of the studies involving CS-related measures in TMD patients. METHODS: A meta-analysis of case-control and cohort/cross sectional studies was conducted. Standardized mean differences (SMD) and 95% confidence intervals (CIs) were calculated for relevant QST outcomes and pooled in a meta-analysis using the random effects model. Twenty-two studies (eleven case-control and eleven cross sectional studies) met the inclusion criteria; eight were included in the meta-analysis (five cross-sectional and three case-control). Patients with TMD had decreased pressure pain thresholds in both trigeminal (five studies; n = 1,985; SMD = -1.55, 95% CI -2.23 to -0.77; P < 0.01) and remote areas (five studies; n = 1,985; SMD = -1.92, 95% CI -2.95 to -0.89; P < 0.01). When analyzing for thermal hyperalgesia (hot and cold pain thresholds), differences were not found in trigeminal areas or remote areas in patients with TMD. The TS qualitative analysis showed strong evidence of spinal hyperexcitability for mechanically evoked pain. CONCLUSION: These meta-analyses support the existence of differences in widespread pressure pain sensitivity in patients with TMD when compared with asymptomatic subjects. Spinal and central hyperexcitability can be found in TMD patients as shown by an increase in mechanical TS.

Objective: Insufficient evidence exists to compare widespread pain (WP), pain sensibility, and psychological factors that occur in patients presenting with chronic neck pain (CNP) or a combination of temporomandibular disorder (TMD) and other complaints. The present study compared the pain sensibility and psychological factors of subjects with CNP with those with TMD + CNP. Design: Cross-sectional study. Setting: Local community. Subjects: A nonprobabilistic convenience sample of 86 persons with CNP or TMD was recruited into three groups: CNP, TMD with myofascial pain in masticatory muscles with cocomitant CNP (TMD + CNP), and asymptomatic control groups consisted of 27, 29, and 30 participants, respectively. Methods: Participants underwent a clinical examination to evaluate WP with computerized assessment based on the pain drawing, pressure pain thresholds (PPT), and psychological factors, which were evaluated using the pain catastrophizing scale (PCS) and the state-trait anxiety inventory (STAI). Results: Statistically significant differences were observed between participants with CNP and TMD + CNP for WP (t = -2.80, P < 0.01, d = -1.06). Post hoc analyses only revealed significant differences between TMD + CNP participants and asymptomatic controls for PPT at extratrigeminal areas. Pearson correlation analyses showed a moderate positive association between symptomatic groups within the WP and STAI ( P < 0.05) and a moderate negative association between PCS and PPT ( P < 0.05) at the right tibialis muscle. Conclusion: TMD + CNP participants had more areas of pain and also showed widespread pain hyperalgesia. Both groups of participants had psychological factors positively associated with STAI and WP; further, PCS and the PPT at the extratrigeminal region were negatively associated with each other in both groups, except for the left tibialis in the TMD + CNP group.

OBJECTIVE: Our aim was to systematically review and meta-analyze the effectiveness of graded activity (GA) or graded exposure (GEXP) for chronic nonspecific low back pain (CNSLBP). METHODS: A literature search of multiple databases (MEDLINE, EMBASE, PEDro, CINAHL, and PsychINFO) was conducted to identify randomized control trials (RCTs). Standardized mean difference (SMD) and 95% confidence intervals (CI) were calculated for relevant outcome measures (pain intensity, disability, quality of life, and catastrophizing). RESULTS: Thirteen RCTs met the inclusion criteria. Only nine studies were included in the meta-analysis. GA was significantly more effective than the control group (CG) for improvements in disability in the short term (three studies: n = 254, SMD = -0.3, 95% CI -0.55 to -0.05, P = 0.02) and long term (two studies: n = 238, SMD = -0.53, 95% CI -0.79 to -0.27, P < 0.0001). GA was significantly less effective than GEXP for the improvement of disability in the short term (two studies: n = 105, SMD = 0.39, 95% CI 0.003-0.78, P = 0.048). GA was also significantly less effective than GEXP at improving catastrophizing in the short term (two studies: n = 105, SMD = 0.48, 95% CI 0.09-0.87, P = 0.02). CONCLUSION: Limited evidence has been found to show that GA significantly reduces disability in the short and long term when compared with the CG in CNSLBP. There is moderate evidence that GEXP more effectively decreases catastrophizing than GA in the short term. No difference was found between GA and other exercise for any variable.

OBJECTIVE: Our aim was to systematically review and meta-analyze the effectiveness of therapeutic patient education for migraine. METHODS: A literature search of multiple electronic databases (MEDLINE, EMBASE, PEDro, CINAHL, and PsychINFO) was conducted to identify randomized control trials (RCTs) published in the English and Spanish languages up to and including May 2013. Two reviewers independently selected the studies, conducted the quality assessment (Delphi list), and extracted the results. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was used throughout the systematic review and meta-analysis. Standardized mean difference (SMD) and 95% confidence intervals (CIs) were calculated for relevant outcome measures (headache frequency, headache disability, self-efficacy, depressive symptoms, and quality of life) and pooled in a meta-analysis using the random effects model. RESULTS: Fourteen RCTs were included in the systematic review. Only nine studies were included in the meta-analysis. The median quality score was 6.14 ± 1.29 (range: 5-9). There was strong-moderate evidence for intermediate-term effectiveness of therapeutic patient education on headache frequency (five studies: N = 940, SMD = -0.24, 95% CI of -0.48 to -0.01, P = 0.03), headache disability (four studies: N = 799, SMD = -1.02, 95% CI of -1.95 to -0.08, P = 0.03), and quality of life (three studies: N = 674, SMD = 0.36, 95% CI of 0.05-0.67, P = 0.02). There was no evidence for either short-term or intermediate-term effectiveness of therapeutic patient education on self-efficacy or depressive symptoms. CONCLUSION: This systematic review revealed strong-moderate evidence for intermediate-term effectiveness of therapeutic patient education for migraine. Further high-quality RCTs are required for conclusive determination of its effectiveness.

Purpose: First, testing an intervention of neuromodulation based on motor imagery and action observation as a promoter of motor adaptation of a complex motor task involving balance. Second, determining what prior balance factors can affect the motor adaptation task. Methods: A double-blind randomized controlled trial was performed. Forty-eight healthy subjects were recruited. The balance of all participants during gait and standing was assessed before adapting to the complex, multi-limb motor task of riding an inverse steering bicycle (ISB). Two interventions were carried out interleaved among trials of adaptation to the motor task: the experimental group (n = 24) was asked to perform neuromodulation (EN) by watching first-person ISB riding through immersive VR glasses and, simultaneously, mentally mimicking the movements. The control group (CG) was asked to watch a slideshow video of steady landscape images. Results: The results showed that the EN group did not improve the motor adaptation rate and induced higher adaptation times with respect to the CG. However, while the motor adaptation success showed a significant dependence on the prior proprioceptive participation in balance in the CG, the EN group did not present any relationship between the prior balance profile and motor adaptation outcome. Conclusions: Results point to a benefit of the visually guided neuromodulation for the motor adaptation of the subjects with low participation of proprioception in balance. Moreover, the results from the control group would allow to disclose prognostic factors about the success of the motor adaptation, and also prescription criteria for the proposed neuromodulation based on the balance profile.
RESUMEN
BACKGROUND: Elbow and wrist chronic conditions are very common among musculoskeletal problems. These painful conditions affect muscle function, which ultimately leads to a decrease in the joint's Range Of Motion (ROM). Due to their portability and ease of use, goniometers are still the most widespread tool for measuring ROM. Inertial sensors are emerging as a digital, low-cost and accurate alternative. However, whereas inertial sensors are commonly used in research studies, due to the lack of information about their validity and reliability, they are not widely used in the clinical practice. The goal of this study is to assess the validity and intra-inter-rater reliability of inertial sensors for measuring active ROM of the elbow and wrist. MATERIALS AND METHODS: Measures were taken simultaneously with inertial sensors (Werium™ system) and a universal goniometer. The process involved two physiotherapists ("rater A" and "rater B") and an engineer responsible for the technical issues. Twenty-nine asymptomatic subjects were assessed individually in two sessions separated by 48 h. The procedure was repeated by rater A followed by rater B with random order. Three repetitions of each active movement (elbow flexion, pronation, and supination; and wrist flexion, extension, radial deviation and ulnar deviation) were executed starting from the neutral position until the ROM end-feel; that is, until ROM reached its maximum due to be stopped by the anatomy. The coefficient of determination (r 2) and the Intraclass Correlation Coefficient (ICC) were calculated to assess the intra-rater and inter-rater reliability. The Standard Error of the Measurement and the Minimum Detectable Change and a Bland-Altman plots were also calculated. RESULTS: Similar ROM values when measured with both instruments were obtained for the elbow (maximum difference of 3° for all the movements) and wrist (maximum difference of 1° for all the movements). These values were within the normal range when compared to literature studies. The concurrent validity analysis for all the movements yielded ICC values ≥0.78 for the elbow and ≥0.95 for the wrist. Concerning reliability, the ICC values denoted a high reliability of inertial sensors for all the different movements. In the case of the elbow, intra-rater and inter-rater reliability ICC values range from 0.83 to 0.96 and from 0.94 to 0.97, respectively. Intra-rater analysis of the wrist yielded ICC values between 0.81 and 0.93, while the ICC values for the inter-rater analysis range from 0.93 to 0.99. CONCLUSIONS: Inertial sensors are a valid and reliable tool for measuring elbow and wrist active ROM. Particularly noteworthy is their high inter-rater reliability, often questioned in measurement tools. The lowest reliability is observed in elbow prono-supination, probably due to skin artifacts. Based on these results and their advantages, inertial sensors can be considered a valid assessment tool for wrist and elbow ROM.
RESUMEN
OBJECTIVES: Low back pain (LBP) is the most prevalent musculoskeletal problem, which implies a high rate of chronicity. The chronicity of symptoms can lead to pain expansion. The main objective of this study was to assess whether there were differences between patients with nonspecific chronic LBP (CLBP) who sought healthcare compared to those who did not in terms of pain expansion. METHODS: Ninety individuals participated in the study and were divided into three groups: 30 patients who sought care; 30 patients who did not seek care; and 30 asymptomatic individuals. The primary variable analyzed was pain expansion. Secondary physical and psychological variables were assessed later, and a regression analysis was performed. RESULTS: Patients who sought help showed significant differences in pain expansion and pain intensity compared with the group who did not seek help, with a medium effect size (0.50-0.79). The regression model for the care-seeking group showed that dynamic balance with the left leg and depression were predictors of percentage pain surface area (34.6%). The combination of dynamic balance, range of movement in flexoextension and depression were predictors of widespread pain (48.5%). CONCLUSION: Patients who soughtcare presented greater pain expansion than patients whodidnot. A combination of functional and psychological variables can significantly predict pain expansion in patients with nonspecific CLBP who seek help.
RESUMEN
Motor adaptation is the ability to develop new motor skills that makes performing a consolidated motor task under different psychophysical conditions possible. There exists a proven relationship between prior brain activity at rest and motor adaptation. However, the brain activity at rest is highly variable both between and within subjects. Here we hypothesize that the cortical activity during the original task to be later adapted is a more reliable and stronger determinant of motor adaptation. Consequently, we present a study to find cortical areas whose activity, both at rest and during first-person virtual reality simulation of bicycle riding, characterizes the subjects who did and did not adapt to ride a reverse steering bicycle, a complex motor adaptation task involving all limbs and balance. The results showed that cortical activity differences during the simulated task were higher, more significant, spatially larger, and spectrally wider than at rest for good performers. In this sense, the activity of the left anterior insula, left dorsolateral and ventrolateral inferior prefrontal areas, and left inferior premotor cortex (action understanding hub of the mirror neuron circuit) during simulated bicycle riding are the areas with the most descriptive power for the ability of adapting the motor task. Trials registration Trial was registered with the NIH Clinical Trials Registry (clinicaltrials.gov), with the registration number NCT02999516 (21/12/2016).
RESUMEN
Objectives: Current literature is scarce about the use of an inertial sensor to measure cervical active range of motion (aROM). The objective of the present study is to determine inter- and intra-reliability in the measurement of cervical aROM using inertial sensors in asymptomatic individuals.Materials and methods: Twenty asymptomatic individuals participated in the study. Two different physiotherapists measured each participant for cervical aROM (6 movements). The sequence of movements and the explanations given were standardized. The rater's order of measurement was randomized.Results: For the intra-rater results, the intraclass correlation coefficient (ICC) values for all cervical movements were good for Rater A (ICC >0.90) and Rater B (ICC >0.90). For the inter-rater results, the ICC values were above 0.75 for all movements, indicating a good level of reliability. Also, values obtained in SEM, MDC90 and LOA indicate good agreement.Conclusion: The data obtained in this study suggest that inertial sensors can be used in clinics due to their high intra- and inter-rater ICC (>0.80). Also, its low economic cost, easy handling, and various utilities make this tool a useful alternative in the measurement of cervical aROM.

OBJECTIVE: To determine if the perceived pain intensity during the application of shock waves (SWs) is a determinant mechanism in producing hypoalgesic changes in pressure pain thresholds (PPTs) in asymptomatic individuals. DESIGN: A randomised, single-blind controlled trial [NCT03455933]. SETTING: University. PARTICIPANTS: Sixty-three asymptomatic individuals. INTERVENTIONS: Participants were randomised into three groups: 1-SWs causing mild pain (SW-DP); 2-SWs generating moderate pain (SW-MP); and 3-cold pressor test (CPT). MAIN OUTCOME MEASUREMENTS: Before and after the intervention, the PPT was evaluated bilaterally at the following points: lateral epicondyle, median nerve in the flexure of the elbow, and tibia. RESULTS: The results showed differences between various groups over time for all PPTs assessments, due to the existence of statistically significant differences in the interaction group x times (dominant arm lateral epicondyle [P < 0.001; η2p = 0.255]; dominant arm median nerve [P = 0.001; η2p = 0.212]; nondominant arm lateral epicondyle [P < 0.001; η2p = 0.275]; nondominant arm median nerve [P < 0.001; η2p = 0.268]; tibia [P = 0.012, η2p = 0.138]). The SW-MP group obtained a significant increase in all the PPT evaluations compared with the SW-DP group (d > 0.80). The CPT group only showed significantly higher results, and of high magnitude (d > 0.80), regarding the SW-DP group for the PPT evaluation in the dominant member. The SW-MP group showed differences compared with the CPT only for the PPT obtained in the nondominant arm. CONCLUSIONS: The findings show that SW treatment generates a hypoalgesic effect on the application point, with moderate pain. Further studies are necessary in order to link these hypoalgesic changes to the activation of the descending inhibitory systems.

BACKGROUND: The purpose of this study was to analyze the relationships between muscular performance consisting of a single repetition on the chair squat exercise (CSQ) and different measures of functional capacity, balance, quality of life and cognitive status in older adults. METHODS: A total of 40 participants (22 women, 18 men; age = 72.2 ± 4.9 years) joined the investigation. Muscular performance was assessed by measuring movement velocity in the CSQ with no external load using a validated smartphone application (PowerLift for iOS). Functional capacity, balance, quality of life and cognitive status were evaluated using the hand-grip strength (HGS) test, the Berg-scale, the EuroQol 5D (EQ-5D) and the Mini mental state examination questionnaire (MMSE). Finally, participants were divided into two subgroups (N = 20) according to their velocity in the CSQ exercise. RESULTS: Positive correlations were obtained between movement velocity in the CSQ and HGS (r = 0.76, p < 0.001), the Berg-scale (r = 0.65, p < 0.001), the EQ-5D (r = 0.34, p = 0.03) and the MMSE (r = 0.36, p = 0.02). Participants in the fastest subgroup showed very likely higher scores in the Berg-scale (ES = 1.15) and the HGS (ES = 1.79), as well as likely higher scores in the MMSE scale (ES = 0.69). DISCUSSION: These results could have potential clinical relevance as they support the use of a time-efficient, non-fatiguing test of muscular performance (i.e., the CSQ) to evaluate functional capacity and mental cognition in older adults.
RESUMEN
A century of research in human brain parcellation has demonstrated that different brain areas are associated with functional tasks. New neuroscientist perspectives to achieve the parcellation of the human brain have been developed to know the brain areas activation and its relationship with different stimuli. This descriptive study aimed to compare brain regions activation by specific tactile input (STI) stimuli according to the Vojta protocol (STI-group) to a non-STI stimulation (non-STI-group). An exploratory functional magnetic resonance imaging (fMRI) study was performed. The 2 groups of participants were passively stimulated by an expert physical therapist using the same paradigm structure, although differing in the place of stimulation. The stimulation was presented to participants using a block design in all cases. A sample of 16 healthy participants, 5 men and 11 women, with mean age 31.31â±â8.13 years was recruited. Indeed, 12 participants were allocated in the STI-group and 4 participants in the non-STI-group. fMRI was used to map the human brain in vivo while these tactile stimuli were being applied. Data were analyzed using a general linear model in SPM12 implemented in MATLAB. Differences between groups showed a greater activation in the right cortical areas (temporal and frontal lobes), subcortical regions (thalamus, brainstem, and basal nuclei), and in the cerebellum (anterior lobe). STI-group had specific difference brain activation areas, such as the ipsilateral putamen. Future studies should study clinical implications in neurorehabilitation patients.

OBJECTIVE: To assess clinical differences in the Achilles tendons of runners with ankle equinus wearing either compressive or standard stockings. DESIGN: Caseâ»control study. METHODS: In this study, we conducted clinical examinations of 98 sportsmen (runners) with equinus, before and after 30 min of running on a treadmill; 49 runners wore compressive stockings and 49 wore standard stockings. Clinical assessments of the runners' Achilles tendons were based on the pressure pain threshold (PPT) and skin temperature analysis. RESULTS: Achilles tendon evaluations identified significant differences in skin temperature modification and PPT between the compressive and standard stocking groups. CONCLUSIONS: Based on our findings, we propose that higher skin temperatures are associated with lower pressure pain thresholds in the Achilles tendons of runners with ankle equinus.
RESUMEN
OBJECTIVES: Compare the immediate effects of a Neurodynamic Mobilization (NM) treatment or foam roller (FR) treatment after DOMS. DESIGN: Double blind randomised clinical trial. SETTING: The participants performed 100 drop jumps (5 sets of 20 repetitions, separated by 2 min rests) from a 0.5-m high box in a University biomechanics laboratory to induce muscle soreness. The participants were randomly assigned in a counter-balanced fashion to either a FR or NM treatment group. PARTICIPANTS: Thirty-two healthy subjects (21 males and 11 females, mean age 22.6 ± 2.2 years) were randomly assigned into the NM group (n = 16) or the FR group (n = 16). MAIN OUTCOME MEASURES: The numeric pain rating scale (NPRS; 0-10), isometric leg strength with dynamometry, surface electromyography at maximum voluntary isometric contraction (MVIC) and muscle peak activation (MPA) upon landing after a test jump were measured at baseline, 48 h after baseline before treatment, and immediately after treatment. RESULTS: Both groups showed significant reduction in NPRS scores after treatment (NM: 59%, p < .01; FR: 45%, p < .01), but no difference was found between them (p > .05). The percentage change improvement in the MVIC for the rectus femoris was the only significant difference between the groups (p < 0.05) at post-treatment. After treatment, only the FR group had a statistically significant improvement (p < 0.01) in strength compared to pre-treatment. CONCLUSION: Our results illustrate that both treatments are effective in reducing pain perception after DOMS whereas only FR application showed differences for the MVIC in the rectus femoris and strength.
RESUMEN
Health care in the ageing population is becoming a crucial issue, due to the quality of life. Physical activity, is of primary importance for older adults. This report compared the physical activity in two active older adults population with functionality, quality of life, and depression symptoms. A cross-sectional study was developed with 64 older adults. Physical activity was assessed through the Yale Physical Activity Survey for classification into a less activity (LA) group and a more activity (MA) group. Afterwards, the other health variables were measured through specific questionnaires: the quality of life with the EuroQol (EuroQol five dimensions questionnaire, EQ-5D), functionality with the Berg balance scale (BBS) and depression symptoms with the geriatric depression scale (GDS). There is a statistical significant difference between groups for the BBS (t=2.21; P=0.03, d=0.27). The Pearson correlation analysis shows in LA group a moderate correlation between the BBS and age (r=-0.539; P<0.01) and EQ-5D (r=0.480; P<0.01). Moreover, both groups had a moderate negative correlation between GDS and the the EQ-5D time trade-off (r=-0.543; P=0.02). Active older adults with different amounts of physical activity differ in the BBS. This functional score was higher in the MA group. When observing to quality of life, only the LA group was negatively associated with age while in both groups were associated with depression index.
RESUMEN
Background. Neck pain (NP) is strongly associated with cervico-craniofacial pain (CCFP). The primary aim of the present study was to compare the neck pain-related disability, pain catastrophizing, and cervical and mandibular ROM between patients with chronic mechanical NP and patients with CCFP, as well as asymptomatic subjects. Methods. A total of 64 participants formed three groups. All participants underwent a clinical examination evaluating the cervical range of motion and maximum mouth opening, neck disability index (NDI), and psychological factor of Pain Catastrophizing Scale (PCS). Results. There were no statistically significant differences between patients with NP and CCFP for NDI and PCS (P > 0.05). One- way ANOVA revealed significant differences for all ROM measurements. The post hoc analysis showed no statistically significant differences in cervical extension and rotation between the two patient groups (P > 0.05). The Pearson correlation analysis shows a moderate positive association between NDI and the PCS for the group of patients with NP and CCFP. Conclusion. The CCFP and NP patient groups have similar neck disability levels and limitation in cervical ROM in extension and rotation. Both groups had positively correlated the NDI with the PCS.
