Body Weight Support (BWS)

What is Intuitive Body Weight Support?

The Benefits of Intuitive Body Weight Support

Vector Intuitive Body Weight Support advantages:

  • Therapy can be started earlier
  • Continually challenge patients while keeping them safe
  • Real-world training prepares patients for life outside of the therapy gym
  • Increase therapy efficiency by allowing a hands-on approach rather than supporting the patient and being constantly concerned about them falling
  • Expand treatment options and shorten recovery times

A Clear Improvement Over Traditional Static Body Weight Support

A patient’s center of mass moves when they take a step up or down. A system that utilizes Intuitive Body Weight Support unloads a percent of a patient’s body weight and, during this movement, maintains that percent at a constant level. Vector achieves Intuitive Body Weight Support by automatically shortening or lengthening the support rope as the patient takes a step up or down. Patients can walk, step up, lunge or kneel more naturally while still being supported.

Traditional static body weight support systems aim to prevent falls but are very restrictive and can feel abnormal. Static systems use a rope or strap of fixed length to provide safety. If a patient elevates or takes a step up, the rope goes slack and no longer provides the necessary unloading, leaving the patient vulnerable to falls, putting both the patient and the therapist at risk. The fixed-length rope restricts downward movement for squats, transitioning to the ground or even natural depressions during gait.

During a step, Intuitive Body Weight Support keeps the rope taught to provide the selected unloading while preventing falls. Static BWS systems provide no such benefits during active movement.

Versatility and Real-World Experience

Over-ground training closely mimics real-world experience. By employing Intuitive Body Weight Support, Vector enables true over-ground training in a wide range of exercises, including:

  • Pre-gait activities (e.g., transfers)
  • Balance exercises
  • Stair climbing
  • Obstacle avoidance
  • Surface changes
  • Treadmill endurance training

While secured in the Vector, a patient can safely feel balance reactions and experience mistakes to achieve motor learning and develop effective movement strategies.

Indication for Use: The Vector Elite system is a body weight support system designed to accelerate physical rehabilitation of patients with severe gait and/or balance impairment. The system unloads a programmed amount of weight to enable the patient to practice walking with less than his or her full body weight.

Do not use the Vector Elite system in patients weighing more than 500 lbs or who have unstable fractures, halo neck supports, uncontrolled high blood pressure or diabetes, or severe osteoporosis.
