The 2000 Yunnan earthquake left 92,479 homeless and destroyed over 41,000 homes.Homelessness among people with mental health problems is much less common in China than in high-income countries, due to stronger family ties, but is increasing due to migration within families and as a result of the one-child policy. A study in Xiangtan found at least 2439 schizophrenic people that have been homeless on a total population of 2.8 million. It was found that "homelessness was more common in individuals from rural communities (where social support services are limited), among those who wander away from their communities (i.e., those not from Xiangtan municipality), and among those with limited education (who are less able to mobilize social supports). Homelessness was also associated with greater age; [the cause] may be that older patients have burned their bridges with relatives and, thus, end up on the streets. "During the Cultural Revolution a large part of child welfare homes were closed down, leaving their inhabitants homeless. By the late 1990s, many new homes were set up to accommodate abandoned children. In 1999, the Ministry of Civil Affairs estimated the number of abandoned children in welfare homes to be 66,000.According to the Ministry of Civil Affairs, China had approximately 2,000 shelters and 20,000 social workers to aid approximately 3 million homeless people in 2014.From 2017 to 2019, the government of Guangdong Province assisted 5,388 homeless people in reuniting with relatives elsewhere in China.
Foot drop is a gait abnormality in which the dropping of the forefoot happens due to weakness, irritation or damage to the deep fibular nerve (deep peroneal), including the sciatic nerve, or paralysis of the muscles in the anterior portion of the lower leg. It is usually a symptom of a greater problem, not a disease in itself. Foot drop is characterized by inability or impaired ability to raise the toes or raise the foot from the ankle (dorsiflexion). Foot drop may be temporary or permanent, depending on the extent of muscle weakness or paralysis and it can occur in one or both feet. In walking, the raised leg is slightly bent at the knee to prevent the foot from dragging along the ground. Foot drop can be caused by nerve damage alone or by muscle or spinal cord trauma, abnormal anatomy, atoxins, or disease. Toxins include organophosphate compounds which have been used as pesticides and as chemical agents in warfare. The poison can lead to further damage to the body such as a neurodegenerative disorder called organophosphorus induced delayed polyneuropathy. This disorder causes loss of function of the motor and sensory neural pathways. In this case, foot drop could be the result of paralysis due to neurological dysfunction. Diseases that can cause foot drop include trauma to the posterolateral neck of fibula, stroke, amyotrophic lateral sclerosis, muscular dystrophy, poliomyelitis, Charcot Marie Tooth disease, multiple sclerosis, cerebral palsy, hereditary spastic paraplegia, Guillain–Barré syndrome, Welander distal myopathy, Friedreichs ataxia and Chronic Compartment Syndrome .
