The treatment of spinal muscular atrophy type 2 (SMA II) is symptomatic. Physical therapy, occupational therapy and assistive devices (walkers, wheelchairs, etc) are generally recommended to help encourage maximum mobility and independence. These interventions may also prevent or delay scoliosis and abnormal contractions of the muscles and tendons. Some children with SMA II may have a difficult time eating enough calories to maintain a normal weight. In these cases, nutritional counseling and/or a feeding tube may become necessary. Breathing problems are also common in people affected by SMA II and may require the use of BiPAP machines or other methods of respiratory support. Some affected children may require surgery to treat scoliosis or severe cases of hip dislocation.
