Since patients tend to have weakness in the affected foot, they may not have the ability to support their body weight. Often, a walker or cane will be used to assist in this aspect.Drop Foot is the inability to dorsiflex, evert, or invert the foot. So when looking at the Gait cycle, the part of the gait cycle that involves most dorsiflexion action would be Heel Contact of the foot at 10% of Gait Cycle, and the entire swing phase, or 60-100% of the Gait Cycle. This is also known as Gait Abnormalities. Diagnosis
Initial diagnosis often is made during routine physical examination. Such diagnosis can be confirmed by a medical professional such as a physiatrist, neurologist, orthopedic surgeon or neurosurgeon. A person with foot drop will have difficulty walking on his or her heels because 
they will be unable to lift the front of the foot (balls and toes) off the ground. Therefore, a simple test of asking the patient to dorsiflex may determine diagnosis of the problem. This is measured on a 0-5 scale that observes mobility. The lowest point, 0, will determine complete paralysis and the highest point, 5, will determine complete mobility.There are other tests that may help determine the underlying etiology for this diagnosis. Such tests may include MRI, MRN, or EMG to assess the surrounding areas of damaged nerves and the damaged nerves themselves, respectively. The nerve that communicates to the muscles that lift the foot is the peroneal nerve.
Another consequence of myelomalacia is improper circulation of blood to the area damaged, resulting in  further damage to the spinal cord. Sport Athletes
Due to extensive physical contact and activity, many athletes become victim to myelomalacia. Any accidents or injuries attained during athletic competition to the spinal cord may result in myelomalacia. Accounts of awkward landing on the ground or being hit intensively have attested to spinal cord injury. Geriatric
With the growth in the elderly population of humans, there has been a rise to myelomalacia. Because the human body begins to deteriorate with age, and because human population is living many years longer, there has been a growth in cases of myelomalacia. As the bones in the body begin to weaken in a process known as osteopenia, the body is more vulnerable to damage. A simple fall may damage the spinal cord and myelomalacia may soon ensue. Diagnosing
There are two tests that can provide a definite diagnosis of myelomalacia; magnetic resonance imaging (MRI), or myelography. Diffuse hyperintensity on T2-weighted imaging, and hypointensity on T1-weighted imaging of the spinal cord can be an indication of the onset or progression of myelomalacia

Treatment
There is no known treatment to reverse nerve damage due to myelomalacia. In some cases, surgery to alleviate the injury to the area may slow or stop further damage. As motor function degenerates, muscle spasticity and atrophy may occur.
