What are the four advantages to using anatomic suspension? (AnsEasy to don/doff Very efficient/functional design Pediatric patients and disarticulation Cost effective What type of suspension system is this describing? "A distal valve permits the air to escape, but does not allow air back in. Increases proprioception. Minimizes pistoning. However, if a person has excessive volume fluctuations or cannot complete donning, this suspension system isn't for them" (Ans- Suction suspe...
