A standing frame is known by many terms, such as a stand, a stander, standing technology, a standing aid, a standing device, a stand-alone, or a standing box. It is an assistive device typically used by an individual who requires a wheelchair for mobility. A standing frame provides alternative positioning from sitting in a wheelchair, and also supports the individual in an upright standing position.
Per available literature, nonambulatory, physically disabled individuals may benefit from the use of a standing frame system for a number of health reasons, such as increasing range of motion; maintaining bone density and muscle strength; increasing cardiovascular endurance; reducing swelling in the lower limbs; decreasing spasticity (muscle overactivity); preventing pressure ulcers; increasing the ability to effectively move air flow through the lungs with improvement in pulmonary function; and improving bowel and bladder function.
Standing frames can be divided into three types: passive (static) stander, mobile (dynamic) stander, and active stander. The best type for an individual depends on height, weight, medical condition, and functional needs. There are a variety of standing frame models available within each type, including motorized or powered and nonmotorized. The type and model of a standing system that is best for an individual depends on the extent of the disability and the size of the individual.
The therapeutic benefits of a powered or motorized option standing frame cannot be clearly disproportionate to its cost if there exists a medically appropriate and realistically feasible alternative item that serves essentially the same purpose.
NONPOWERED PASSIVE (STATIC STANDERS)
The passive (static) standers remain in place and cannot be self-propelled. There are many models of passive standers. Two examples are sit-to-stand and multipositional standers.
Sit-to-stand standers (e.g., EasyStand StrapStand™and EasyStand Evolv™) are highly functional because they can be used in sitting and standing and can usually be positioned at any angle between sitting and standing. A sit-to-stand stander requires the individual to have head control and fairly good trunk control.
Multipositional standers (e.g., EasyStand Bantam™) can be reversed so the individual can be placed in a prone (on the belly) or supine (on the back) position, depending on the individual’s abilities. These standers can be more difficult to use because they are sometimes closer to the floor, and transferring the individual in the stander can require two people; however, there are benefits to the prone/supine stander. For example, if the individual has poor head control, supine positioning can be employed. Then, when the individual develops better head control, the same stander can be utilized in a prone position to develop stronger neck and trunk muscles.
NONPOWERED MOBILE (DYNAMIC) STANDERS
A mobile (dynamic) stander allows individuals with upper body strength to self-propel. There are various models of mobile standers (e.g., Standing Dani®, Rifton Mobile Standers™, EasyStand Evolv™ Mobile, Rabbit Mobile Standing Frame and EasyStand Bantam™ Mobile option). A sit-to-stand stander uses a series of pulleys and wheels that allow the individual to self-propel while in a standing position, with minimal effort. Some mobile standers have a power option, in which the wheels are driven by motors and the stander is controlled by a joystick similar to a power wheelchair. Mobile standers are best for individuals who have good head control and upper body strength. For example, individuals diagnosed with spinal cord injuries, spina bifida, and cerebral palsy can benefit from both the added mobility and the standing position that a mobile stander provides.
NONPOWERED ACTIVE STANDERS
The active standers create reciprocal movement of the arms and legs while standing. This is a newer option in standing frames (e.g., EasyStand® Glider™). These standers have a “glider” attachment that allows the person to use either the arms alone or a combination of arms and legs to operate the mechanism and “glide” in a reciprocal walking-type pattern. Like the mobile stander, the individual in the active stander needs good head control and upper body strength, unless there is a caregiver who is able to assist.
SUMMARY
There are various types and many models available within each category of stander. The standing frame that best benefits the individual should be based on the extent of the individual's disability, size, and home environment.
