What is the difference between complete and incomplete paraplegia?
In complete spinal cord injuries, the spinal cord is fully severed and function below the injury site is eliminated. In comparison, incomplete SCIs occur when the spinal cord is compressed or injured, but the brain’s ability to send signals below the site of the injury is not completely removed.
Who discovered Bulbocavernosus reflex?
Bulbocavernosus reflex (BCR) Bors and Blinn first described the BCR in 1959 [14], which is also known as clitoroanal [15], penilo-cavernosus [16], and Osinski reflex [17]. Blaivas et al.
What does Bulbocavernosus mean?
bulbocavernosus muscle, also called Bulbospongiosus, a muscle of the perineum, the area between the anus and the genitals. In the male, it surrounds the bulb (the enlarged inner end of the structure that surrounds the urethra) of the penis and can be contracted to expel the last drops of urine or semen.
What is a T4 paraplegic?
So for example, complete injury to spinal nerves at the T4 bone is known as T4 paraplegia. The same applies below this in the lumbar region, where the first vertebra is called the L1 running downwards to L5, and then below this again in the sacral region (S1 to S5).
What does T4 and T5 control?
The T1-T4 thoracic sections control primarily chest muscles and organs, such as the heart and lungs. The T5 – T8 vertebrae affect the abdominal muscles, as well as some of the chest.
What is the bulbocavernosus test?
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.
What is bulbocavernosus reflex used for?
Bulbocavernosus Reflex. What is Bulbocavernosus Reflex? Bulbocaverosus reflex (BCR) is a polysynaptic reflex which is used to test for the presence of spinal shock and is basically used to identify and record the presence of a spinal cord injury or neurogenic impotence (erectile dysfunction due to a neurological disease).
Is bulbocavernosus reflex positive or negative after spinal cord injury?
Positive and Negative Reflex When there is a cervical or thoracic cord injury, it is likely that absence of the bulbocavernosus reflex or negative reflex would be a result and would also signify presence of spinal shock and injury. The spinal shock may progress but then may resolve within 48 hours after injury.
What is the significance of the bulbocvernosus contraction (BCR)?
In case of a complete lesion, the presence of BCR is indicative of intact S2-S4 spinal reflex arcs and loss of supraspinal inhibition, d … The BCR consists of the contraction of the bulbocavernosus muscle in response to squeezing the glans penis or clitoris, and is mediated through the pudendal nerve.
