Physical therapist attitude and opinion about cervical spine examination: A national Spanish survey

Patient-reported outcome measurements (PROMs): Use during the physical therapy practice and associated factors

OBJECTIVE

To assess the current level of routine use of psychosocial-related patient-reported outcome measurements (PROMs) in physical therapy practice and which physical therapist-level factors are associated with the use of these measurement instruments.

METHODS

We conducted an online survey study among Spanish physical therapists involved in the treatment of LBP patients in Public Health Service, Mutual Insurance Companies, and private practice during 2020. Descriptive analyses were conducted for reporting the number and instruments utilized. Thus, sociodemographic and professional features differences between PTs using and not using PROM were analyzed.

RESULTS

From 485 physiotherapists completing the questionnaire nationwide, 484 were included. A minority of therapists routinely used psychosocial-related PROMs (13.8%) in LBP patients and only 6.8% did so through standardized measurements instruments. The Tampa Scale for Kinesiophobia (28.8%) and the Pain Catastrophizing Scale (15.1%) were used most frequently. Physiotherapists working in Andalucía and País Vasco regions, in private practice environments, educated in psychosocial factors evaluation and management, considering psychosocial factors during the clinical practice and expecting patients' collaborative attitudes demonstrated significantly greater use of PROMS (p < 0.05).

CONCLUSIONS

This study showed that the majority of physiotherapists in Spain do not use PROMs for evaluating LBP (86.2%). From those physiotherapists using PROMs, approximately the half use validated instruments such as the Tampa Scale for Kinesiophobia or the Pain Catastrophizing Scale while the other half limit their evaluation to anamnesis and non-validated questionnaires. Therefore, developing effective strategies to implement and facilitate the use of psychosocial-related PROMs would enhance the evaluation during the clinical practice.

Inter-Examiner Disagreement for Assessing Cervical Multifidus Ultrasound Metrics Is Associated with Body Composition Features

Ultrasound imaging (US) is a biosensing technique that is widely used in several healthcare disciplines (including physiotherapy) for assessing multiple muscle metrics, such as muscle morphology and quality. Since all biosensors need to be tested in order to demonstrate their reliability, accuracy, sensitivity, and specificity, identifying factors that affect their diagnostic accuracy is essential. Since previous studies analyzed the impact of sociodemographic but not body composition characteristics in US errors, this study aimed to assess whether body composition metrics are associated with ultrasound measurement errors. B-mode images of the lumbar multifidus muscle at the L5 level were acquired and analyzed in 47 healthy volunteers by two examiners (one experienced and one novice). The cross-sectional area, muscle perimeter, and mean echo intensity were calculated bilaterally. A correlation analysis and a multivariate linear regression model were used for assessing the inter-examiner differences with respect to body composition metrics. The results demonstrated good-to-excellent reliability estimates for the cross-sectional area, muscle perimeter, aspect ratio, roundness, circularity, and mean brightness metrics (all ICC > 0.85). However, solidity showed unacceptable reliability (ICC < 0.7). Age, height, total lean mass, trunk lean mass, and water volume were associated with inter-examiner disagreement on mean echo intensity. Cross-sectional area, perimeter, and roundness measurement errors were associated with lean mass and water volume.

Changes in stiffness at active myofascial trigger points of the upper trapezius after dry needling in patients with chronic neck pain: a randomized controlled trial

BACKGROUND/OBJECTIVE

Since, to our knowledge, the effects of dry needling (DN) on active myofascial trigger point (MTrP) stiffness have not been analyzed previously with shear wave elastography (SWE), our aim was to compare the effects of a single session of DN and sham DN applied to the most active MTrP located in the upper trapezius muscle on clinical outcomes.

METHODS

A randomized, double-blinded sham-controlled trial was conducted; 60 patients were randomized into an experimental (DN) or sham (sham DN) group. Baseline data including sociodemographic and clinical characteristics were collected. SWE and pain pressure thresholds (PPTs) at the MTrP and a control point located 3 cm laterally were the main outcomes assessed before and 10 min after the interventions.

RESULTS

Patients receiving DN interventions experienced greater increases in the control point PPTs immediately after receiving the intervention compared with sham DN (p < 0.05), but no differences were found for the MTrP (p > 0.05). Post-intervention PPT improvements were found at both locations for both groups (p < 0.01). No significant changes for either MTrP or control locations were found for SWE outcomes in either group (all ps > 0.05). No significant within-group SWE differences were found in the DN or sham DN groups (p > 0.05).

CONCLUSION

A single session of DN or sham DN applied to active MTrPs located in the upper trapezius muscle produced no detectable changes in stiffness at the MTrP or control locations. Real DN induced an immediate analgesic response at both MTrP and control locations, while sham DN induced an immediate MTrP response.

Ultrasound assessment of deep cervical extensors morphology and quality in populations with whiplash associated disorders: An intra- and inter-examiner reliability study

BACKGROUND

Ultrasound imaging (US) has shown to be a reliable and valid tool for assessing muscle morphology and quality. However, most studies have focused on asymptomatic populations.

OBJECTIVE

To investigate intra- and inter-rater reliability estimates of muscle morphology and quality of cervical multifidus (CM) and short rotators (SR) in patients with whiplash associated disorders (WAD).

DESIGN

An intra- and inter-examiner reliability study.

METHODS

US images were acquired in a blinded fashion in 34 patients (35% males) by two experienced and two novice examiners. Cross-sectional area (CSA), perimeter, mean echo-intensity (EI) and the percentage of fatty infiltration were assessed twice, one-week apart, in a randomized order. Reliability estimates (i.e., intra-class correlation coefficients -ICC-, standard error of measurement -SEM-, minimal detectable change, mean of measurements, absolute and percent errors) were calculated.

RESULTS

Intra-examiner reliability for experienced assessors ranged from good to excellent for CM and SR (ICC_3,1 = 0.888-0.975 and 0.810-0.964 respectively) and from moderate-to-good for novices (ICC_3,1 = 0.708-0.790 and 0.655-0.796 respectively). The agreement between the experienced examiners was moderate to good (ICC_3,2 = 0.737-0.899 and 0.728-0.899 CM and SR respectively); between novice and experienced examiners was moderate to good (ICC_3,2 = 0.617-0.873 and 0.657-0.766 CM and SR respectively); and between novice examiners was moderate-to-good for CM (ICC_3,2 = 0.610-0.777) and moderate for SR (ICC_3,2 = 0.600-0.730).

CONCLUSION

CM and SR intra-examiner reliability was good-to-excellent for novice and experienced examiners. However, inter-examiner reliability was clinically acceptable just for experienced examiners at the C4/C5 level in WAD populations.

Is Shear-Wave Elastography a Clinical Severity Indicator of Myofascial Pain Syndrome? An Observational Study

Since manual palpation is a subjective procedure for identifying and differentiate Myofascial Trigger Points -MTrPs-, the use of Shear Wave Elastography -SWE- as an objective alternative is increasing. This study aimed to analyze pain pressure thresholds -PPTs- and SWE differences between active MTrPs, latent MTrPs and control points located in the upper trapezius to analyze the association of SWE features with clinical severity indicators (e.g., pain extension area, PPTs, neck pain and neck disability). An observational study was conducted to calculate the correlation and to analyze the differences of sociodemographic, clinical and SWE features on 34 asymptomatic subjects with latent MTrPs and 19 patients with neck pain and active MTrPs. Significant PPT differences between active with latent MTrPs (p < 0.001) and control points (p < 0.001) were found, but no differences between latent MTrPs and control points (p > 0.05). No stiffness differences were found between active MTrPs with latent MTrPs or control points (p > 0.05). However, significant control point stiffness differences between-samples were found (p < 0.05). SWE showed no significant correlation with clinical severity indicators (p > 0.05). No stiffness differences between active and latent MTrPs were found. Neck pain patients showed increased control point stiffness compared with asymptomatic subjects. SWE showed no association with clinical severity indicators.
