In children, symptoms may include: * Lesions, hairy patches, dimples, or fatty tumours on the lower back * Foot and<unk>  deformities * Weakness in the legs (loss of muscle strength and tone) * Change in or abnormal gait including awkwardness while running or wearing the tips or side of one shoe * Low back pain * Scoliosis (abnormal curvature of the spine to the left or right) * Urinary irregularities (incontinence or retention)<unk>  may go undiagnosed until adulthood, when sensory, motor, bowel, and bladder control issues emerge. This delayed presentation of symptoms relates to the degree of strain on the<unk> <unk>  over time. Tethering may also develop after<unk> <unk>  injury. Scar tissue can block the flow of fluids around the<unk> <unk> . Fluid pressure may cause cysts to form in the<unk> <unk> , a condition called syringomyelia. This can lead to additional loss of movement or feeling, or the onset of pain or autonomic nervous system symptoms. In adults, onset of symptoms typically include: * Severe pain (in the lower back and radiating into the legs, groin, and perineum) * Bilateral muscle weakness and numbness * Loss of feeling and movement in lower extremities * Urinary irregularities (incontinence or retention) * Bowel control issues Neurological symptoms can include a mixed picture of upper and lower motor neuron findings, such as amyotrophy, hyperreflexia, and pathologic plantar response, occurring in the same limb. Profound sensory changes, such as loss of pain, temperature, and proprioceptive sensations, are common. Last, progressive symptoms of a neuropathic bladder are noted on over 70% of adult patients, versus only 20% to 30% of children. These symptoms include urinary frequency and urgency, feeling of incomplete voiding, poor voluntary control, and urge and stress incontinence. Chronic recurrent infections are common and occasionally lead to nephrolithiasis (kidney stones), kidney failure, or kidney transplantation. Female patients also give a history of ineffective labor and postpartum rectal prolapse, presumably due to an atonic pelvic floor.
