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)

Interface pressure mapping 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. These trainings are intended for individuals with disabilities, family members, home care providers, personal care attendants and others working with individuals with paralysis-causing conditions. Learn how to borrow and use pressure mapping technology. Help prevent life-threatening injuries!

Four trainings were held in 2017 and additional trainings are currently under development for late 2018, including a live webinar opportunity. The trainings are conducted by Mary Jo Wagner, OTR/L, ATP, of the Department of Developmental Services. Participants are awarded a certificate of attendance by the Massachusetts Rehabilitation Commission.

In addition, NuMotion sponsored a webinar in July of 2018 on pressure mapping for clinicians. It is presented by Kim Davis, MSPT, ATP. The webinar is now archived on their website and free to watch (click the streaming link): Clinical Guidelines for Interface Pressure Mapping
