The study included 170 patients in whom the BCR was examined at a mean of 7 years post SCI. If the neurologic examination reveals a likelihood of the reflex being present (e.g., in the case of tetraplegia or high paraplegia, not related to a vascular injury, then perhaps the use of the anal wink would be appropriate as a first choice. 2018;14:4754. Intraoperative BCR monitoring is a reliable predictor of voiding function following surgery in adult patients undergoing lumbosacral spinal tumor surgery and shows no significant difference in voiding between maintained and disappeared BCR groups 6-months postoperatively. volume8, Articlenumber:24 (2022) The sacral examwhat is needed to best care for our patients? BCR was negative in 45%. This seems to be a somewhat specious argument since the proper method of elicitation of the reflexes involves penetration of the anus with a finger to feel the contraction. The bulbocavernosus reflex (BCR), bulbospongiosus reflex (BSR) or "Osinski reflex" is a polysynaptic reflex that is useful in testing for spinal shock and gaining information about the state of spinal cord injuries (SCI). Jean Jacques Wyndaele. The author declares that they have no conflict of interest. Kirshblum S, Eren F. Anal reflex versus bulbocavernosus reflex in evaluation of patients with spinal cord injury. No potential conflict of interest was reported by the authors. The cutoff value of the BCR amplitude reduction was placed between groups 1 and 2 (zone 1: cutoff 50%), groups 2 and 3 (zone 2: cutoff 25%), and group 3 and its subgroup (zone 3: cutoff zero, present or lost).

Your insights are needed to transform us into a better research content provider for researchers. The . With a mean interval of 45 weeks, BCR changed in 32% of a subset of 44 patients (14 became positive, 3 negative), while the neurological condition did not change and no treatments had been given that could influence the outcome. Changes over time were explored in a subset of patients. The importance of the bulbocavernosus reflex. Here, we have two thoughtful and well-written papers, that for the most part agree. JQ commented on the text, made corrections, and helped rewrite the revision text. The choice of which reflex to use should be determined by the need for clinical information. 2020. Marino RJ. Previnaire JG. The official designation of a single reflex limits the choice of tools available to a clinician as there are differences between the anal reflex and the BCR. Within 72 hours post-trauma, the bulbocavernous reflex of all . The anal reflex provides a better first option as a non-invasive clinical assessment of sacral reflex status in clinical practice in SCI as the testing for the anal reflex is less intrusive and already being performed as part of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) by pinprick stimulation of the S4-5 dermatome. Bulbocavernosus reflex Anal sphincter contraction in response to squeezing the glans penis or tugging on an indwelling Foley catheter Reflex mediated by S2-4 and used in patients with spinal cord injury DTR Scale We are not big believers in grading reflexes (grading muscle power is much more useful). 2020;6:2. WJJ collected the file data, put them in a database, made evaluations, wrote the text, and rewrote the revision text. 2020;32:12545. Alternatively, in the situation of a cauda equina or conus injury, perhaps the BCR should be performed first. The third issue is that for the majority of cases the patient will have a catheter inserted and the BCR can be elicited by simply giving a slight tug on the tube, thereby eliminating the need to make contact with the patient other than the finger to detect the contraction. Methods . For thoracic and lumbar cases, the same muscles were used apart from deltoid and biceps.

Prognosis for ambulation based on reflexes early after SCI should not be linked to current descriptions of spinal shock and the view of spinalshock, based on the absence of reflexes and the recovery of Reflexes in a caudal to rostral sequence, is of limited clinical utility and should be discarded. 6011000124106~MAPRULE~TRUE. 2019;8:658.

Hattori T, Hirayama K, Kita K, Yasuda K, Yamashiro Y. The importance of the anal exam in neurologic classification of spinal cord injury. Changes over time were explored in a subset of patients. Calabr RS, Naro A, Pullia M, Porcari B, Torrisi M, La Rosa G, et al. The data show that a negative BCR may not only be due to a disrupted reflex nervous pathway, but may also be caused by a difficulty to provoke the reflex. However, the reliability of elicitation of the BCR is somewhat lower than the anal reflex. For instance the bulbocavernosus reflex (BCR) may have predictive power for sphincter control and sexual function that is not present in the anal reflex [3]. [Absence of anal reflex in patients with central nervous system diseases]. Niu X, Wang X, Ni P, Huang H, Zhang Y, Lin Y, et al. A second issue is that the choice of testing a reflex should be based on the information necessary to answer a clinical question, not by social, cultural or religious mores. volume6, Articlenumber:4 (2020) Neurological urology.

What is the clinical meaning of a negative bulbocavernosus reflex in spinal cord injury patients?. MV of the pelvic floor is a promising method to reduce segmental spasticity and improve ED in men with incomplete SCI, however, the findings require confirmation through a randomized clinical trial with a larger sample size and longer trial period to examine long-term after effects. In: Voduek DB, Boller F, editors. Samdani A, Chafetz RS, Vogel LC, Betz RR, Gaughan JP, Mulcahey MJ. In the clinical setting the bulbocavernosus reflex (BCR) is elicited by squeezing the glans penis and digitally palpating the contraction of the bulbocavernosus (BC) muscle. Global Spine J.

Bulbocavernosus or anal reflex, one or both should be tested after spinal cord injury. The BCR is complementary to the voluntary contraction of the external anal sphincter and should be added to ISNCSCI and ISAFSCI classifications, which should ultimately benefit patient care and research activities. A significant correlation between the level of SCI and video-urodynamic findings was showed, but clinical examination cannot by predict bladder function; urodynamic testing is also necessary.

The bulbocavernosus reflex is the most frequently used sacral reflex test and typically involves electrical stimulation of the dorsal penile nerve with recording of the subsequent motor response in the bulbocavernosus muscle.20 Both the afferent and efferent responses of this reflex travel via the pudendal nerve. suggests that under certain circumstances ephedrine may be preferable to phenylephrine because of phenylephrine's negative effects on cardiac output and cerebral oxygenation .
