Working With The Older Client: Part 1
Working with the older client: Part 1
By Chris Gellert, PT, MMusc & Sportsphysio, MPT, CSCS, AMS
Introduction
According to the 2012 Census, people over the age of 65 make up almost 14% of the US population. That means there are over 43 million seniors (adults 65 or older) today, with the numbers continuing to grow, reaching 70 million by 2030. This aging population creates a unique opportunity for the fitness professional to work with. In this article, we will review the effects of aging on the musculoskeletal system, learn simple functional assessments and understand benefits of strength strengthening. In part 2, strength training guidelines and programming for common aging conditions will be discussed.
Effects of Aging on the Musculoskeletal System
The aging process involves changes to various structures and numerous systems within the body. Research has shown that skeletal muscles change with age, specifically type II, where there is a decreased in these fibers, that atrophy over time, and decrease in size (Brunner et al. 2007). Research has consistently shown that muscle strength decreases with age(Lindle RS, Metter E. 1997). Physiologically it has been studied that maximal strength capacity reaches a peak sometime around the second or third decade of life, and by the fifth decade, begins a gradual decline(Peterson et al. 2010). The strength of people in their 80s is about 40% less than that of people in their 20s(Chiung-Ju Liu, 2011). The decline in muscle strength is associated with an increased risk of falls and physical disability in older adults.
Functional assessments of older client
Balance tests
Assessing an older client’s balance needs to be objective and not guesswork. There are many tests available, but few are objective, measureable, and supported with research as the timed up and go test and the sit to stand test.
1)Timed Up and Go Test
Use a standard armchair. Place the line ten feet from the chair. The score is the time
taken in seconds to complete the task. The subject is encouraged to wear regular
footwear and to use any customary walking aid. No physical assistance is given.
Give the following instructions:
• Rise from the chair
• Walk to the line on the floor (10 feet)
• Turn, return to the chair
• Sit down again
Figure 1. TUG test
Scoring: Persons who take 10 seconds or less to complete this sequence of maneuvers are at
low risk of falling. Persons who take >20 seconds to complete this sequence are at high risk of falling(Bohannon, RW., 2006).
2)Sit to stand test
Have the client sit with their back against the back of the chair. Ask the client to stand from the seated positing, counting each stand aloud so that the client remains oriented. Stop the test when the patient achieves the standing position on the 5th repetition.

3) Functional squat
The squat is a classic fundamental primal movement someone typically performs on a daily
basis. Whether it is to perform to pick something up or move something. The squat is a
movement that requires proper ankle and hip mobility, while stability is required at the knee
and lumbar spine. Understanding the functional anatomy and muscle recruitment is fundamental
when prescribing this exercise with any client.
Figure 3. Squat picture Figure 4. Squat analysis
Movement Analysis:
As the body descends, the hip flexors concentrically contract with slight lumbar flexion, while the knees undergo flexion, glute maximus and hamstrings eccentrically contract. At the ankle, dorsiflexion occurs, where the anterior tibialis(concentrically contracts) while the gastrocnemius eccentrically contracts.
Returning to an upright position(vertical), the opposite occurs. The hip flexors eccentrically contract, there is slight lumbar extension, while the knee transitions from flexion to extension. Hip extension occurs via the glute maximus, while the hamstrings concentrically contract.
Ankle plantar flexion occurs with the concentric contraction of the gastrocnemius while there is eccentric contraction of anterior tibialis.
Benefits of Strength Training for improving function in older adults
Muscles behind the movement
There are numerous benefits of strength training for older adults. However, it is important to understand the muscles behind everyday movement. Large muscle groups, including shoulders, arms, trunk, hips and legs, are important to perform activities of daily living(ADLs) and are susceptible to the aging process, training should targets these muscle groups. The latissimus dorsi muscle (assists with sit to stand). Glute maximus is a primary hip extensor muscle involved in walking and climbing stairs. The hamstring muscles are important in flexing the knee and extending the hip, which are involved in everyday activities such as walking, sit to stand, and negotiating stairs. Glute medius and minimus muscles are lateral stabilizers that are important for getting in and out of bed or car or stepping into a bathtub.
Research: Benefits of Strength Training and Balance
Strength training physiologically improves strength of bones and connective tissue, size of fast and slow-twitch fibers, reduces blood pressure, improves blood flow with many more benefits. Research has shown specifically that strength training improves gait mechanics(Persch et al. 2009), reduces the risk for falls in the elderly (Karlson, MK et al. 2013, Trombetti, A et al. 2011, Sherrington et al. 2008 & Zhen-Bo, Cao, et al 2006).
Balance defined is defined as the ability to maintain an upright posture during both
static and dynamic tasks(Benjuya, Melzer, & Kaplanski, 2004). Maintaining balance
involves a complex interaction among the sensory, vestibular and visual systems.
Aging dampens reaction time and muscle strength impairing, in some people, the ability to control a fall. In older adults, possessing lateral stability is a key contributor to maintaining balance control. Lateral stability is controlled by both the glute medius and glute minimus muscles (Orr, R., et al. 2008).
It has been shown there are several contributing factors that contribute to a person with falling. One major factor is leg weakness, particularly in hamstrings and glute maximus. Which has been commonly reported as an important fall-risk factor. Individuals exhibiting this sign have 4.9 times the risk of falling than people with normal strength (Bird, L. et al., 2009, & Rubenstein, 2006).
Studies by (Nolan, M et al. 2010 and Ozcan et al. 2005 and Moreleand, JD 2004) identify that ankle mobility, specifically lack of dorsiflexion is another contributing factor for increased falls in seniors.
Finally, several studies found that decreased plantar flexion strength is a contributing factor. (Menz et al. 2005) examined 171 men and women with a mean age 80.1, had their foot posture, range of motion, strength, and vision, sensation, strength, reaction time, and balance examined over a 12 month period. Results: seventy-one participants (41%) reported falling during the follow-up period. Those who fell exhibited decreased ankle flexibility, decreased plantar tactile sensitivity, and decreased plantarflexor strength.
Additional factors including impaired proprioception (joint position sense), decreased flexibility and fear of falling (Visual Analogue Scale) as risk factors for falls per the research.
Summary
Aging is inevitable. Falls can be prevented. Arming yourself with more knowledge about the body will enable you to help your clients’ age gracefully reaching optimal health. A multi-component exercise intervention program that consists of strength, endurance, and balance training appears to be the best strategy for improving gait, balance, and strength, as well as reducing the rate of falls in elderly individuals(Cadore, E., 2013).

What is spinal stenosis?
Background: A narrowing within the vertebral canal coupled with hypertrophy of
the spinal lamina and ligamentum flavum or facets as the result of age related degenerative
process.
Contributing factors: Posture, prior job or lifestyle(sat for numerous hours), an individual who runs frequently, sits for excessive hours, and doesn’t regular stretch.
Presentation: Client presents in posterior pelvic tilt, creating shortened and tight hamstrings with tight lumbar extensors.
Evidenced training recommendations: Important to avoid end of range extension based exercises should be avoided as they close the neural foramen(ie. cobra press-up).
Focus: Perform flexion based exercises such as; knee to chest, prayer stretch and reverse abdominal crunch.
Lower extremity stretching should focus stretching the inflexible hamstrings, hip flexors
and quadriceps, which are commonly tight in stenotic individuals. Yoga and pilates can also
be effective to improve a client’s flexibility and core stability. Progressive resistance training
exercises such as lat pull-down, seated mid row, seated reverse flyes, and horizontal leg press
are all-safe to teach a client with lumbar stenosis based on science.

"Teaching The Science Behind The Movement"
Have clients with history of shoulder impingement?
Background: Shoulder impingement is a common condition affecting men> women(2:1) where someone complains of anteromedial pain that has gradually developed.
Contributing factors: History of individual working out predominantly shoulder press, chest press, anterior raises and front of body. Muscle imbalances, type of work and lifestyle.
Two types: Primary(Mechanical) impingement: Is caused by a mechanical dysfunction
such as bursa, AC joint, acromion, humerus or rotator cuff/supraspinatus tendon beneath the coracromial arch. This is a mechanical problem that may result from sub acromial crowding.
Secondary(Structural) impingement: Is caused by a relative decrease in sub acromial space
caused by instability of the glenohumeral joint, tight posterior capsule and weakness of
scapulothoracic musculature.
Evidenced training recommendations:
Emphasis is to create scapular stability/balance the shoulder muscles dynamically.
• Posterior capsule stretching
• Chest stretching
• Scapular protraction(strengthening serratus anterior/upper trapezius/low trapezius
biomechanically, together all cause an upward rotation of the scapula to
maintain the sub acromial space above 90 degrees of shoulder elevation.
• Scapular retraction via mid row with tubing or cable (decreases load to
front of the shoulder).
• External rotation strengthening: ideal is side lying which is more isolative for teres minor
and infraspinatus recruitment(decreases the load to the anterior shoulder).
Prevention: Keep stretching pectorals and posterior capsule. Avoidance of shoulder press or military press, avoidance of anterior raises and client engaging in regular “balanced “ workout. Targeting weaker phasic muscles(rhomboids, low trapezius, external rotators, scapular depressors).
