Efficacy of Proprioceptive Neuromuscular Facilitation and Closed Kinetic Chain Exercises on Quadriceps and Plantar Flexors Among Geriatrics

Elderly population’s quality of life decline at a faster rate and hence there is an increase in mortality rates. Anti-aging process can be emphasised by scheduled exercise programs which enhances beneficiary adaptations in vascular physiology and neurovascular coupling. The mobility function is disturbed due to reduced muscle strength, inappropriate activation of motor units, insufficiency to maintain balance which leads to higher risk offall in the elderly people.Closed kinetic chain exercises control the musculoskeletal system against gravity at rest and in motion thereby protecting the postural stability. PNF has a positive effect on balance and functionality in older adults. Materials and Method: A Quasi experimental study was done for 50 community dwelling elderly people from “Vishranthi Charitable Trust” with mean age of 73±4 years who were selected based on the inclusion criteria. Closed kinetic chain exercises for quadriceps and plantar flexors along with PNF technique such as anterior elevation and posterior depression were given and followed up for 3 weeks. The pretest and post test values were obtained using 6-min walk test, the knee extensor strength measurement and fall risk questionnaire.

Result: There was a significant difference in 6-min walk test, fall risk questionnaire p<0.05 in improving the strength of quadriceps and plantar flexors, and there was non-significant difference in the knee extensor strength.

Conclusion: Hence the study concludes that there is an impact on PNF and Closed kinetic chain exercise on quadriceps and plantar flexors to enhance balance among geriatrics.
