Efficacy of a strength-based exercise program in patients with chronic tension type headache: a randomized controlled trial

Disentangling preventive effects of differential exercise types on tension-type headache: a component network meta-analysis of randomized controlled trials

BACKGROUND

The effectiveness of exercise for tension-type headache (TTH) is unclear because of the complexity of exercise regimens-usually the combination of different types of exercise. We aimed to estimate the effectiveness of exercise for TTH and to test the incremental effect of each type of exercise by component network meta-analysis (CNMA).

METHODS

We searched Ovid Medline, Embase, and the Cochrane Library from database inception to 25 December 2023, and a supplementary search was conducted on 10 February 2025. We included randomized controlled trials of exercise, including aerobic, resistance, and stretching exercise, in adults with TTH. The primary outcome was headache frequency, and secondary outcomes were headache intensity and medication use.

RESULTS

Twelve trials with 759 participants were included. There were no significant differences between exercise and usual care in reducing headache frequency at the end of treatment with very low certainty evidence (mean difference [MD] -2.30, 95% [confidence interval] CI -8.86 to 4.26), while CNMA suggested that resistance exercise significantly reduced headache frequency (incremental mean difference [iMD] -6.00, 95% CI -9.10 to -2.90) and stretching exercise increased headache frequency (iMD 4.60, 95% CI 1.20 to 8.00). Exercise was better than usual care in reducing headache intensity (MD -2.29, 95% CI -3.23 to -1.34); the CNMA suggested that no single type of exercise had the greatest effect.

CONCLUSION

Resistance exercise could be considered an effective and accessible treatment for patients with TTH. But our study was limited by heterogeneity and inconsistency of results, and more studies are warranted.

The efficacy of physiotherapy approaches in chronic tension-type headache: a systematic review and meta-analysis

BACKGROUND

Although pharmacologic therapies are considered the first choice for the treatment of chronic tension-type headache (CTTH), physiotherapy and rehabilitation approaches are also used in the management of patients with CTTH. This study aimed to investigate the efficacy of physiotherapy approaches in CTTH through a systematic review and meta-analysis.

METHODS

The following electronic databases were searched, PubMed and Web of Science databases. Common primary outcomes from randomized controlled trials (RCTs) were changes in the intensity and duration of headaches, headache frequency, disability and headache impact. The methodologic quality (completeness of reporting and risk of bias) of trial reports included in systematic reviews was assessed using the Physiotherapy Evidence Database scale ratings. We also performed data synthesis and quantitative analysis of the eligible data.

RESULTS

Nine RCTs were included in the review. Seven studies related to intensity of headache (IH), three on headache frequency (HF), three on headache duration (HD), and two on headache impact were eligible for quantitative analysis. Analysis of the data showed that neck-shoulder strength exercises, electroacupuncture, and approaches targeting muscle relaxation improved the IH (-1.17 (-1.86, -0.49) p < 0.01) and reduced the HD (-0.71 (-1.31, -0.12), p = 0.02); the approaches targeting muscle relaxation and neck-shoulder strength exercises induced a significant decrease in the HF (-1.36 (-2.47, -0.26), p = 0.02) in patients with CTTH in comparison with the control groups.

CONCLUSIONS

Neck-shoulder strength exercises and muscle relaxation are effective in reducing the intensity, duration, and frequency of headaches and electroacupuncture causes significant improvement in the duration and intensity of headaches in patients with CTTH.

[Temporal trend of the global prevalence rate of tension-type headache in children and adolescents in 1990-2021]

OBJECTIVES

To investigate the prevalence of tension-type headache (TTH) in children and adolescents aged 0-19 years globally in 1990-2021, and to provide a basis for the prevention and treatment of TTH.

METHODS

Based on the Global Burden of Disease Study data, the age-standardized prevalence distribution of TTH and its changing trend were analyzed among the children and adolescents aged 0-19 years, with different sexes, age groups, sociodemographic index (SDI) regions and countries/territories.

RESULTS

The age-standardized prevalence rate (ASPR) of TTH in children and adolescents aged 0-19 globally in 2021 was 17 339.89/100 000, which was increased by 1.73% since 1990. The ASPR in females was slightly higher than that in males (1990: 17 707.65/100 000 vs 16 403.78/100 000; 2021: 17 946.29/100 000 vs 16 763.09/100 000). The ASPR in adolescence was significantly higher than that in school-aged and preschool periods (1990: 27 672.04/100 000 vs 10 134.16/100 000; 2021: 28 239.04/100 000 vs 10 059.39/100 000). Regions with high SDI exhibited a higher ASPR than the other regions, with significant differences in prevalence rates across different countries. From 1990 to 2021, there was a slight increase in global ASPR, with an average annual percentage change (AAPC) of 0.06%. Females experienced a smaller increase than males based on AAPC (0.04% vs 0.07%). There was reduction in ASPR in preschool and school-aged groups, with an AAPC of -0.02%, while there was a significant increase in ASPR in adolescence, with an AAPC of 0.07%. ASPR decreased in regions with low-middle and low levels of SDI, with an AAPC of -0.02% and -0.04%, respectively, while it increased in regions with middle SDI, with an AAPC of 0.24%.

CONCLUSIONS

There is a consistent increase in the ASPR of TTH in children and adolescents aged 0-19 years globally, with significant differences across sexes, age groups, SDI regions and countries/territories.

Diagnostic Accuracy of Ultrasound Imaging and Shear Wave Elastography to Discriminate Patients with Chronic Neck Pain from Asymptomatic Individuals

OBJECTIVES

The aim of this study was to determine and compare the capability of several B-mode ultrasound (US) and shear wave elastography (SWE) metrics to differentiate subjects with chronic non-specific neck pain from asymptomatic subjects.

METHODS

A diagnostic accuracy study recruiting a sample of patients with chronic neck pain and asymptomatic controls was conducted. Data collection included sociodemographic information (i.e., gender, age, height, weight and body mass index), clinical information (pain intensity assessed using the Visual Analogue Scale and pain-related disability using the Neck Disability Index) and B-mode ultrasound and shear wave elastography features of the cervical multifidus muscle (cross-sectional area, perimeter, mean echo intensity, fat infiltration, shear wave speed and Young's modulus). After analyzing between-group differences for left/right sides, cases and controls, and males and females, the area under the receiver operating characteristic (ROC) curve, the optimal cut-off point, the sensitivity, the specificity, the positive likelihood ratio (LR) and negative LR for each metric were calculated. A total of 316 individuals were recruited in this study (n = 174 cases with neck pain and n = 142 asymptomatic controls).

RESULTS

No significant differences (p > 0.05) were found between cases and controls for most variables, except for fatty infiltration, which was significantly higher in chronic neck pain cases (p < 0.001). Gender differences were significant across all US and SWE metrics (all, p < 0.001 except p = 0.015 for fatty infiltrates). A slight asymmetry was observed between the left and right sides for area (p = 0.038). No significant interactions between group, gender and side (all metrics, p > 0.008) were identified. Fatty infiltration was the most effective discriminator, with a ROC value of 0.723, indicating acceptable discrimination. The optimal cut-off point for fatty infiltration was 25.77, with a moderate balance between sensitivity (59.8%) and specificity (20.5%). However, its positive likelihood ratio (LR) of 0.75 suggests limited usefulness in confirming the condition.

CONCLUSIONS

Fatty infiltration was significantly higher in individuals with chronic idiopathic neck pain compared to those without symptoms, while other muscle metrics were similar between both groups. However, since fat infiltration had moderate diagnostic accuracy and the other metrics showed poor discriminatory power, US cannot be used solely to discriminate patients with idiopathic neck pain.

Cervical Multifidus and Longus Colli Ultrasound Differences among Patients with Cervical Disc Bulging, Protrusion and Extrusion and Asymptomatic Controls: A Cross-Sectional Study

The aim of this study was to analyze the differences in morphological and histological features of the cervical multifidus (CM) and longus colli (LC) muscles among patients with cervical disc bulging, protrusion, or extrusion. Fifteen patients with cervical disc bulging (20% male, mean age: 48.5, standard deviation (SD) 7.5 years), fifteen with cervical disc protrusion (6% male, mean age: 43, SD 7.8 years), and fifteen with cervical disc extrusion (40% male, mean age: 44, SD 8 years) diagnosed via clinical and imaging findings participated in this study. Additionally, fifteen asymptomatic controls (40% male, mean age: 40.4, SD 9.7 years) were also included. The following ultrasound measurements, cross-sectional area (CSA), anterior-posterior distance (APD), lateral dimension (LD), and mean echo-intensity (EI) of the CM and LC at C5-C6 level were examined by an assessor blinded to the subject's condition. The results revealed no group ×side significant differences among the groups (p > 0. 00625). However, group effects were found for APD and MEI of the CM (p = 0.006 and p < 0.001, respectively) and CSA, APD and MEI of the LC (all, p < 0.001). The LD of the LC muscle and the APD and LD of the CM were negatively associated with related disability (p < 0.01; p < 0.05 and p < 0.01, respectively), and pain intensity was negatively associated with LC APD and LD (both p < 0.05). These results suggest that US can be used to detect bilateral morphological changes in deep cervical flexors and extensors to discriminate patients with cervical disc alterations.
