Physical Functioning Improvements in Older Adults Following a Proprioceptive Neuromuscular Facilitation-Based...

Area of Science:

• Gerontology
• Exercise Physiology
• Rehabilitation Science

Background:

• Older adults with functional impairment often experience declines in physical capacity.
• Proprioceptive neuromuscular facilitation (PNF) is an exercise strategy aimed at improving physical functions like gait and sit-to-stand (STS) ability.
• PNF may be beneficial for enhancing functional capacity in elderly individuals experiencing physical limitations.

Purpose of the Study:

• To evaluate the impact of a PNF-based intervention on the functional capacity of older adults with limited physical functioning.
• To compare the effects of PNF exercises with resisted sit-to-stand and walking against a control group performing the same activities without resistance.

Main Methods:

• A randomized clinical trial involving 25 older adults (mean age 80.4 years) assigned to either a PNF group or a control group.
• Interventions consisted of eight sessions over four weeks, with the PNF group receiving manual resistance during exercises.
• Functional capacity was assessed using the Short Physical Performance Battery, gait speed, STS, timed up and go, static balance, and handgrip strength.

Main Results:

• Significant interactions between time and group were observed for the Short Physical Performance Battery, gait speed, STS, and static balance.
• The PNF group demonstrated significant improvements in the Short Physical Performance Battery, gait speed, and STS.
• The control group showed significant declines in gait speed and handgrip strength, while the PNF group did not.

Conclusions:

• The PNF concept, incorporating resisted exercises, is a promising intervention for improving physical functioning in older adults.
• This approach shows potential for mitigating functional decline and enhancing mobility in elderly individuals at high risk of disability.
