Women with Chronic Pelvic Pain Demonstrate Increased Lumbopelvic Muscle Stiffness Compared to Asymptomatic Controls

Background: Although lumbopelvic muscle stiffness is commonly clinically assessed in women with chronic pelvic pain (CPP), it has not been objectively quantified in this population, and its association with other pain-related impairments has not yet been established. Objective: To compare superficial lumbopelvic muscle stiffness in women with and without CPP. In addition, pressure pain threshold (PPT) was compared between groups and the associations between muscle stiffness and PPT were assessed in women with CPP. Study Design: Case-control. Methods: Muscle stiffness and PPT of 11 lumbopelvic muscles were assessed in 149 women with CPP and 48 asymptomatic women. Subjective outcome measures, including pelvic floor function, health history, and psychosocial outcomes, were collected before muscle stiffness and PPT measurements. Analysis of covariance was used to compare muscle stiffness differences between groups, and independent t-tests were used to compare PPT between groups. Associations between measurements of PPT and muscle stiffness were calculated using correlation analysis. Results: Five of the 11 muscles measured were significantly stiffer in women with CPP than those without CPP (p < 0.05). PPT was significantly decreased in all muscles measured in women with CPP; however, there was not a significant association between muscle stiffness and PPT in women with CPP. Conclusion: The study identified the abdominal lumbopelvic muscles that have increased stiffness in women with CPP compared to asymptomatic women. In addition, muscle stiffness and PPT are two distinct impairments within this population. The results suggest that women with CPP have peripheral muscle impairments, which may be addressed without intravaginal or intrarectal intervention. Clinical Trial Registration: NCT04851730.

Association between pelvic pain bothersomeness and pain sensitivity: A community-based cross-sectional study of young adult females in the Raine Study

OBJECTIVE

Pelvic pain has been associated with augmented nociceptive processing, but large studies controlling for multiple potential confounding factors are lacking. This study investigated the association between pelvic pain bothersomeness and pain sensitivity in young adult women, accounting for potential confounding factors.

DESIGN

Cross-sectional study.

SETTING

Community-dwelling sample.

POPULATION

The Raine Study Gen2-22 year follow-up (n = 475).

MAIN OUTCOME MEASURES

The experience of bothersomeness related to pelvic pain was determined from a question in the Urogenital Distress Inventory short form. Pain sensitivity was measured using pressure pain and cold pain thresholds. Potential confounding factors included ethnicity, marital status, highest level of education, income, waist-hip ratio, level of activity, sleep quality, smoking, comorbidity history, C-reactive protein level, musculoskeletal pain experience and psychological distress.

RESULTS

Three hundred and sixty-two women (76.2%) reported no pelvic pain bothersomeness, 74 (15.6%) reported mild pelvic pain bothersomeness and 39 (8.2%) reported moderate-severe pelvic pain bothersomeness. After adjusting for marital status (and test site), moderate-severe pelvic pain bothersomeness was associated with a lower pressure pain threshold (i.e. greater pressure pain sensitivity) (coefficient -51.46, 95% CI -98.06 to -4.86, p = 0.030). After adjusting for smoking, moderate-severe pelvic pain bothersomeness was also associated with a higher cold pain threshold (i.e. greater cold pain sensitivity) (coefficient 4.35, 95% CI 0.90-7.79, p = 0.014).

CONCLUSIONS

This study suggests augmented nociceptive processing as a contributing factor in pelvic pain bothersomeness for some women. Thorough assessment of women who present clinically with pelvic pain should consider pain sensitivity as a potential contributing factor to their presentation.

Association of physical therapy techniques can improve pain and urinary symptoms outcomes in women with bladder pain syndrome. A randomized controlled trial

Purpose:

to verify the effects of biofeedback (BF) and manual therapy (MT) associated with transcutaneous electrical nerve stimulation (TENS) or postural exercises (PE) in the treatment of bladder pain syndrome (BPS) in women regarding pain and urinary symptoms.

Materials and Methods:

a parallel-randomized controlled trial was conducted in BPS patients diagnosed according to NIH clinical criteria. Two specialized physiotherapists applied demographic and validated questionnaires of perineal and suprapubic pain (VAS), urinary symptoms and problems (ICSI and ICPI) and sexual function (FSFI) and a physical assessment was made to identify myofascial trigger points. Thirty-one women, mean age 51.8 ± 10.9 were randomized in three groups of treatment consisting of ten weekly sessions of BF and MT (Conventional group); BF, MT, and TENS (TENS group); and BF, MT, and PE (Postural group).

Results:

Postural group improved perineal and suprapubic pain after treatment (p<0.001 and p=0.001, respectively), and the suprapubic pain improvement remained persistent at 3 months of follow up (p=0.001). Postural group improved urinary symptoms and problems after treatment (p<0.001 and p=0.005, respectively) and during follow up (p<0.001 and p=0.001).

Conclusions:

Biofeedback and manual therapy associated with postural exercises showed a significant improvement in perineal and suprapubic pain and urinary symptoms after treatment and during follow-up. Both results suggest a possible role for the use of this physiotherapy technique to treat BPS patients. Longer follow-up and a larger number of patients are necessary to confirm these conclusions.

Is There a Difference in Whole Body Standing Posture in Women With Urinary Incontinence Based on the Presence of Myofascial Dysfunction in the Pelvic Floor Muscles?

OBJECTIVE

The purpose of this study was to assess the prevalence of postural changes in women who had urinary incontinence (UI) with myofascial dysfunction (MD) and women who had UI without MD in the pelvic floor muscles (PFM).

METHODS

A cross-sectional study was performed with 234 women who had UI and were at least 18 years old at the urogynecology outpatient clinic of a tertiary academic hospital. The International Consultation on Incontinence Questionnaire-Short Form and the International Consultation on Incontinence Questionnaire-Overactive Bladder were used to collect urinary data. Standing postural assessment was performed using photogrammetry in anterior, posterior, and right and left lateral views and was analyzed with Postural Assessment Software. MD was defined as pain of any intensity during palpation of the PFM, and the strength of these muscles was evaluated using the Modified Oxford Scale.

RESULTS

The prevalence of MD in women with UI was 51.7% (121/234). Women with MD had significantly smaller angles in the horizontal alignment of the pelvis in the right-side view (mean [SD] = -11.9 [6.9] degrees and -9.6 [7.1] degrees), left-side view (-13.6 [6] degrees and -11.5 [6.6] degrees), and vertical alignment of the body in the left-side view (3 [1.5] degrees and 3.4 [1.5] degrees), showing anterior pelvic tilt and posterior displacement of the body.

CONCLUSION

Women with UI and MD had greater anterior pelvic tilt and posterior displacement of the body than women without dysfunction.

IMPACT

This study informs physical therapists and other health care professionals about the prevalence of MD in the pelvic floor muscles of women with UI and highlights the need to rule out MD, because it appears to be a concomitant impairment in women who self-report UI. During a postural screen, health care professionals should look for anterior pelvic tilt relative to horizon when evaluating posture in women with UI and MD. The findings of postural changes in women with MD and UI may influence the PFM assessment.

LAY SUMMARY

Women with involuntary urinary loss, pain, and stiffness in the pelvic area may show changes in posture associated with this condition.

Acute Effects of Tecar Therapy on Skin Temperature, Ankle Mobility and Hyperalgesia in Myofascial Pain Syndrome in Professional Basketball Players: A Pilot Study

(1) Background: Myofascial pain syndrome (MPS) is a clinical condition characterized by localized non-inflammatory musculoskeletal pain caused by myofascial trigger points. Diathermy or Tecar therapy (TT) is a form of noninvasive electro-thermal therapy classified as deep thermotherapy based on the application of electric currents. This technique is characterized by immediate effects, and its being used by high performance athletes. (2) Methods: A total of thirty-two participants were included in the study who were professional basketball players. There was a 15-person Control Group and a 17-person Intervention Group. TT was applied in the Intervention Group, while TT with the device switched off (SHAM) was applied in the Control Group. The effects were evaluated through the Lunge test, infrared thermography, and pressure threshold algometry at baseline, 15, and 30 min after the intervention. (3) Results: the Intervention Group exhibited a greater increase in absolute temperature (F_[1,62] = 4.60, p = 0.040, η²_p = 0.13) compared to the Control Group. There were no differences between the groups in the Lunge Test (F_[1.68,53.64] = 2.91, p = 0.072, η²_p = 0.08) or in pressure algometry (visual analog scale, VAS) (F_[3.90] = 0.73, p = 0.539, η²_p = 0.02). No significant short-term significant differences were found in the rest of the variables. (4) Conclusions: Diathermy can induce changes in the absolute temperature of the medial gastrocnemius muscle.

Widespread Pain Hypersensitivity and Lumbopelvic Impairments in Women Diagnosed with Endometriosis

OBJECTIVE

To explore hypersensitivity to pain and musculoskeletal impairments in the lumbopelvic area in women with and without endometriosis.

METHODS

This cross-sectional study included 66 women (41 women with endometriosis and 25 healthy women). Pain and related catastrophizing thoughts were assessed through a numeric rating scale, pressure pain thresholds (PPTs), the slump test, and the Pain Catastrophizing Scale. Lumbopelvic muscles were evaluated through ultrasound imaging, flexor/extensor resistance tests, and the lumbopelvic stability test.

RESULTS

Women with endometriosis showed increased self-reported intensity of current pelvic pain (CuPP), reduced local PPTs (42.8-64.7% in the affected area, P-value <.001) and higher prevalence of lumbar nerve root impingement/irritation pain and catastrophizing thoughts (P-value ≤.002). Moreover, affected women showed decreased thickness of transversus abdominis, reduced resistance of flexor and extensor trunk muscles and lower lumbopelvic stability (P-values <.030). Endometriosis stage and severity of CuPP were related to worse results in these parameters.

CONCLUSIONS

The presence of pain sensitization signs and lumbopelvic impairments, more pronounced in patients with stage IV endometriosis and moderate/severe CuPP, warrants the development of rehabilitation interventions targeting pain and lumbopelvic impairments in women with endometriosis.

Does low back pain or leg pain in gluteus medius syndrome contribute to lumbar degenerative disease and hip osteoarthritis and vice versa? A literature review

[Purpose] Gluteus medius syndrome is one of the major causes of back pain or leg pain and is similar to greater trochanteric pain syndrome, which also presents with back pain or leg pain. Greater trochanteric pain syndrome is associated with lumbar degenerative disease and hip osteoarthritis. The objective of this review was to demonstrate gluteus medius syndrome as a disease entity by reviewing relevant articles to elucidate the condition. [Methods] Gluteus medius syndrome was defined as myofascial pain syndrome arising from the gluteus medius. We performed a search of the literature using the following keywords: “back pain”, “leg pain”, “greater trochanteric pain syndrome”, “degenerative lumbar disease”, “hip osteoarthritis”, and “gluteus medius”. We reviewed articles related to gluteus medius syndrome and described the findings in terms of diagnosis and treatment based on the underlying pathology. [Results] A total of 135 articles were included in this review. Gluteus medius syndrome is similar as a disease entity to greater trochanteric pain syndrome, which presents with symptoms of low back pain and leg pain. Gluteus medius syndrome is also related to lumbar degenerative disease, hip osteoarthritis, knee osteoarthritis, and failed back surgery syndrome. [Conclusion] Accurate diagnosis of gluteus medius syndrome and appropriate treatment could possibly improve lumbar degenerative disease and osteoarthritis of the hip and knee, as well as hip-spine syndrome and failed back surgery syndrome.

Somatic and psychosocial determinants of symptom severity and quality of life in male and female patients with chronic pelvic pain syndrome

AIMS

To investigate the combined impact of somatic and psychosocial factors on symptom severity and physical and mental quality of life (QoL) in male and female patients with chronic pelvic pain syndrome (CPPS).

METHODS

We examined 234 patients aged 18 to 84 years attending an interdisciplinary outpatient clinic for patients with CPPS in Hamburg, Germany. Using self-reports, we assessed CPPS symptom severity (NIH-CPSI), with the female counterpart of each male anatomical site used in the questionnaire for women; physical and mental QoL (SF-12) as well as symptoms of depression (PHQ-9) and anxiety (GAD-7); pain catastrophizing cognitions (PCS); social support (F-SozU) and medication intake. The presence of trigger and tender points was assessed in a physiotherapy examination. Hierarchical multiple regression analysis was calculated to analyze the contribution of somatic and psychosocial variables on CPPS symptom severity. Analyses were repeated with physical and mental QoL as outcomes.

RESULTS

In the overall model, the intake of pain medication (B = 3.78, SE = 1.25, p = .006), the presence of depressive symptoms (B = 0.40, SE = 0.15, p = .01) and pain catastrophizing (B = 0.18, SE = 0.05, p = .001) significantly predicted CPPS symptom severity. Corresponding analyses revealed a differential pattern of factors predicting physical and mental QoL, whereas higher levels of depressive symptoms were consistently associated with diminished mental (B = -0.63; p < .001) and physical QoL (B = -0.85; p < .001).

CONCLUSION

Present results emphasize the importance of psychosocial factors, in particular of depression, in CPPS symptom severity and both physical and mental QoL and give support to an integrated treatment concept encompassing both psychological support and somatic aspects of the disease.
