Recumbency is not necessary. These machines have been used successfully for patients with extremely severe back disc problems and since these can be set to almost no gravity, pulmonary patients are also able to us them to obtain aerobic benefits.
The downside is the device's cost. The cheapest found in some gyms runs ~$30-35,000. These gyms usually charge $100-200 per month or separately per visit or by the minute for its use. The ones, like used here in the Med Center for injury rehab run more than $75, 000-100,000.
Keep in mind the company producing these various models disclaim medical benefits from all but its most expensive "medical" units.
