Gain control of your health and life! Pressure mapping technology and scales available statewide. Silhouettes of people in wheelchairs

Wheelchair Accessible Scales and Pressure Mapping Technology

MassMATCH is pleased to announce the availability of scales for wheelchair users and digital pressure mapping technology (PMT) in Western, Central and now Eastern Massachusetts. The Weight and Seating Independence Project (WSIP) is making this essential equipment accessible to individuals with disabilities, families, caregivers and other professionals. With funding from the Christopher and Dana Reeve Foundation and the Massachusetts Rehabilitation Commission, MassMATCH is helping individuals with paralysis take control of their own health.

Trainings with Pressure Mapping Technology (PMT)

What is Interface Pressure Mapping?

Interface pressure mapping is a mat with sensors connected to a computer that is used to show pressure points when someone is sitting or lying down. Too much pressure at one point can lead to skin breakdowns or other injuries. Pressure mapping technology is useful for determining appropriate seating and positioning for users of wheelchairs.

Getting Started with Pressure Mapping

On March 20th, 2019, 2 pm ET. MassMATCH is hosting a live 60-minute webinar training on borrowing and using pressure mapping technology.

Webinar Description:

“I live in fear of another pressure ulcer!”
“I lost three months in bed, time I will never get back.”
-- MassMATCH spinal cord injury focus group participants.

In response to an overwhelming community need, MassMATCH has now acquired and made available pressure mapping systems for use by individuals, caregivers, and clinicians statewide and free of charge. Join us to learn about pressure mapping and the prevention of pressure injuries associated with paralysis. We will review the causes of pressure injury and the basics of prevention, the role of pressure mapping, and how to borrow and use the equipment. Experts report 60% of persons with spinal cord injury (SCI) are likely to develop a pressure injury in their lifetime and 1 in 10 who do so may die of resulting complications. Pressure injuries, however, are not confined to persons with SCI, and are associated with a range of paralysis-causing conditions including ALS, TBI, CP, MS, Polio, Stroke, Spinal Muscular Atrophy, and Transverse Myelitis.
