Final answer:
Neuromuscular Training (NMT) is best suited for improving gait, whereas other goals like promoting social skills or managing depression may require different therapeutic approaches.
Step-by-step explanation:
NMT, or Neuromuscular Training, would be most appropriate for the goal of improving gait. This type of intervention is designed to address physical and neurological aspects of movement. In contrast, supporting social skills or processing bereavement might be better served through cognitive therapies or support groups that promote empathy and social skills, whereas managing depression could involve psychotherapy, electroconvulsive therapy, deep-brain stimulation, and medication such as monoamine oxidase inhibitors or selective serotonin reuptake inhibitors.
