A 1994 report found that of those who were in a vegetative state a month after a trauma, 54% had regained consciousness by a year after the trauma, whereas 28% had died and 18% were still in the vegetative state. For non-traumatic injuries such as strokes, only 14% had recovered consciousness at one year, 47% had died, and 39% were still vegetative. Patients who were vegetative six months after the initial event were much less likely to have recovered consciousness a year after the event than in the case of those who were simply reported vegetative at one month. A New Scientist article from 2000 gives a pair of graphs showing changes of patient status during the first 12 months after head injury and after incidents depriving the brain of oxygen. After a year, the chances that a PVS patient will regain consciousness are very low and most patients who do recover consciousness experience significant disability. The longer a patient is in a PVS, the more severe the resulting disabilities are likely to be. Rehabilitation can contribute to recovery, but many patients never progress to the point of being able to take care of themselves. The medical literature also includes case reports of the recovery of a small number of patients following the removal of assisted respiration with cold oxygen. The researchers found that in many nursing homes and hospitals unheated oxygen is given to non-responsive patients via tracheal intubation.
Causes
Plantar fasciitis is a common cause of calcaneal spurs. When stress is put on the plantar fascia ligament, it does not cause only plantar fasciitis, but causes a heel spur where the plantar fascia attaches to the heel bone. The considerations that affect plantar heel pain are the alignment of the foot with lower leg, foot and ankle mobility, strength and endurance of muscle. External influences on plantar heel pain are the amount of time spent on feet while exercising or standing, type of footwear used and type of floor surfaces.Calcaneal spur develops when proper care is not given to the foot and heels. People who are obese, have flat feet, or who often wear high-heeled shoes are most susceptible to heel spurs. Flat feet can potentially be attributed to the minimal amount of ankle dorsiflexion during stance phase of the gait cycle causing more tension on the plantar fascia. Diagnosis
Spur outgrowths can be detected through physical exam followed by a lateral foot x-ray. Treatment
It is often seen as a repetitive stress injury, and thus lifestyle modification is typically the basic course of management strategies. For example, a person should begin doing foot and calf workouts. Strong muscles in the calves and lower legs will help take the stress off the bone and prevent heel spurs. Icing the area is an effective way to get immediate pain relief. There are several means to get pain relief from plantar heel pain. Plantar heel pain can be a precursor to many pathologies of the foot.
