PTWA Geriatric SIG Approved

The PTWA Geriatric Special Interest Group (GSIG) was approved by PTWA members at the 2017 PTWA Chapter Meeting held in October. The goal of the GSIG is to provide a means by which PTWA PT and PTA members who have a common interest in geriatrics may share information, have a platform to access current guidelines/research on best practice, and meet and promote the interests of its membership, the chapter, the APTA and our profession.


  • Provide a platform for professional interaction between PTs and PTAs within the state of Washington and across multiple practice settings.
  • Provide a platform for discussion of current topics and issues concerning the geriatric physical therapy community.
  • Participate in events promoting geriatric physical therapy care and APTA membership.
  • Represent the interests of GSIG members before the official decision-making bodies of the chapter, APTA and other components.
  • Provide a platform for accessing local resources within our state that support healthy aging.


  • Networking with professionals in your state with a common interest in geriatrics.
  • Opportunities to find community organizations to best support the care of our aging adults.
  • Receive important information about the workings of your state chapter.
  • Receive important information to support effective, evidence-based physical therapy care for our rapidly growing aging adult population in an ever-changing healthcare system.

We look forward to your/PTWA support and participation with this group. Best practice and care for our patients is first on our mind.

The Skinny on Sarcopenia

One definition of sarcopenia by Santilli et al1, states: Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength and it is strictly correlated with physical disability, poor quality of life and death. Risk factors for sarcopenia include age, gender and level of physical activity.

To diagnosis sarcopenia three of the following need to be present:

  • HR >84 bpm at rest
  • Orthostasis: a decrease in systolic 20 bpm or diastolic 10 bpm within three minutes of standing compared to sitting or supine
  • Muscle weakness: a general 3/5, no specific muscle group
  • Impaired mobility: need assistive device, need assist with bed mobility, difficulty with transfers
  • Heart rate increases 10-20 bpm with verbal exam

As PTs we should be drooling at this. All of these are WELL within our scope to treat and VERY treatable! Treatment of deconditioning typically targets activity HR 20 beats greater than resting (light load). And remember to educate your patients to be patient as recondition takes two times longer than deconditioning.

Ikezoe2 found that older adults need knee extension force of 45 percent of their body weight and sit to stand of 5.6 times in 30 seconds to retain their ability to walk independently.

There is a wealth of research to support the benefits of low intensity strength programs that improve knee extension strength and functional mobility in frail older adults. Westoff3 demonstrated significant strength increases using these parameters: one to three sets of four to eight reps, with one minute rest, using TheraBand and using criteria that when they can perform three sets with good form to increase load.

Sarcopenia cost over 18 billion dollars in healthcare costs per year.  We as PTs have the power to impact that and significantly improve the quality of life of our older adults! What a great job we have!!
