Ability appropriate balance training interventions have been shown to improve postural control scores and reduce falls risk in the elderly across a number of investigations. There is also a very limited body of evidence that suggests that sensory-targeted interventions (e.g. Massage or joint mobs) have a positive effect on postural control in the elderly. There is a growing body of evidence to support this theory in individuals with ankle joint pathologies.
While not familiar with the literature, sensory reweighting studies will help connect somatosensory function with the postural control system.
really it is absolutely necessary to work on balance and postural control especially in this population already having their ages somatosensory disturbances.
in fact it is critical in preventing falls and recovery after hospitalization for example.
