Diagnosis, Rehabilitation and Preventive Strategies for Pudendal Neuropathy in Cyclists, A Systematic Review

At What Point in the Menstrual Cycle Are the Pelvic Floor Muscles at Their Weakest?

Pelvic floor muscle (PFM) strength is a critical factor for optimal pelvic floor function. Fluctuations in strength values based on different phases of the menstrual cycle (MC) could signify a need for a paradigm shift in evaluating, approaching, and planning training. This research aims to examine and contrast the pelvic floor muscle strength during different phases of the menstrual cycle. A prospective observational study employing digital assessment with the modified Oxford scale and vaginal dynamometry measurements was performed, in order to assess the baseline strength and the contraction strength of the PFMs in eumenorrheic females at three different phases of the MC: the early follicular phase (EFP), the late follicular phase (LFP), and the mid-luteal phase (MLP). During two complete cycles, tympanic temperature and body weight were measured and the urinary luteinizing hormone concentration was tested to determine the time of ovulation. In total, 216 dynamometric measurements of PFM strength were obtained from eighteen nulliparous women (25.72 ± 5.03 years). There were no differences between the baseline strength (p = 0.886) and the contraction strength (p = 0.756) with the dynamometric speculum. In the post hoc analysis, the baseline strength, contraction strength, and strength showed no significant differences between MC phases. As no differences in PFM strength in women were found, the PFMs do not seem to be weaker at any time during the menstrual cycle. It appears that the assessment, establishment, and monitoring of a PFM training program could be initiated at any point in the cycle.

Sexual health and treatment-related sexual dysfunction in sexual and gender minorities with prostate cancer

Prostate cancer treatment has substantial effects on sexual health and function. Sexual function is a vital aspect of human health and a critical component of cancer survivorship, and understanding the potential effects of different treatment modalities on sexual health is crucial. Existing research has extensively described the effects of treatment on male erectile tissues necessary for heterosexual intercourse; however, evidence regarding their effects on sexual health and function in sexual and gender minority populations is minimal. These groups include sexual minority - gay and bisexual - men, and transgender women or trans feminine people in general. Such unique effects in these groups might include altered sexual function in relation to receptive anal and neovaginal intercourse and changes to patients' role-in-sex. Sexual dysfunctions following prostate cancer treatment affecting quality of life in sexual minority men include climacturia, anejaculation, decreased penile length, erectile dysfunction, and problematic receptive anal intercourse, including anodyspareunia and altered pleasurable sensation. Notably, clinical trials investigating sexual outcomes after prostate cancer treatment do not collect sexual orientation and gender identity demographic data or outcomes specific to members of these populations, which perpetuates the uncertainty regarding optimal management. Providing clinicians with a solid evidence base is essential to communicate recommendations and tailor interventions for sexual and gender minority patients with prostate cancer.

Could Horse Gait and Induced Pelvic Dynamic Loads in Female Equestrians Be a Risk Factor in Pudendal Neuralgia?

Pudendal Neuralgia (PN) is a rare, debilitating disease caused by damage to the pudendal nerve, which innervates the anus, rectum, perineum, lower urinary tract, and genitalia. Although its etiology remains scientifically unknown, a number of sports practices, including horse-riding, are reported as triggering and/or aggravating factors. The present work summarizes the experimental measurements of the contact pressure at the interface between the rider and saddle, for a population of 12 experienced female riders. These tests reveal that dynamic horseback-riding leads to high levels of peak pressures in the perineal region, which confirms that the practice of equine sports may cause neuropathologies such as PN. All collected data will be used as boundary conditions in a future numerical 3D model aimed at locating the possible areas of pudendal nerve crushing.

Preventive strategies, exercises and rehabilitation of hand neuropathy in cyclists: A systematic review

BACKGROUND

Recreation, transportation and sport are the most common uses of bicycles. Unfortunately, repetitive bicycle use can also cause injuries, such as osteoarticular direct and undirect traumatisms and sometimes compression nerve entrapment caused by an extrinsic compressive force.

PURPOSE

The aim of the study is to define diagnostic process, preventive strategies, and treatment of ulnar and median neuropathies in cyclists.

STUDY DESIGN

Systematic review.

METHODS

A search was conducted on PubMed, EMBASE, the Cochrane Library, and Web of Science. Two reviewers independently reviewed articles and came to a consensus about which ones to include. The authors excluded all duplicates, articles involving individuals with other sport-related injuries than cycling, and articles unrelated to peripheral neuropathies. Articles were included if hand palsy was due to peripheral compression of ulnar or median nerve in cyclists.

RESULTS

The search identified 15,371 articles with the keywords "Peripheral Nervous System Diseases" OR "neuropathy" OR "ulnar palsy" OR "median palsy" AND "bicycling" OR "bike" OR "bicycle" OR "cyclist". The reviewers analyzed 48 full texts. There were 20 publications that met the criteria and were included in the systematic review. These articles were used to describe the main methods used for diagnosis, prevention and treatment of hand neuropathy of cyclists.

CONCLUSION

Despite the range of treatment available for peripheral neuropathies, a unique and common protocol is lacking on this specific topic. For this reason, we delineate a definitive recovery protocol to show the best therapeutic methodologies present in the current literature. Preventive strategies, period of rest since the beginning of the symptomatology, rehabilitation training with muscle strengthening, orthoses at night are the first strategies, but if the symptoms persist, pharmacologic treatment and eventual surgical decompression are sometimes the unique solution.
