Manual beds use hand cranks to adjust the bed. While these can be affordable options, they may be difficult for a patient to operate by his/herself, especially if s/he has limited mobility. The operator must have sufficient arm and shoulder strength to turn the cranks. For this reason, a manual hospital bed may be the best option for individuals who do not need frequent adjustments.
