Seven exercises that build real lumbar stability include the bird dog, dead bug, glute bridge, side plank, pelvic tilt, cat-cow, and the modified curl-up. These movements target the deep stabilizing muscles of the lower back, including the multifidus and transverse abdominis, which act as a natural brace around the spine. For older adults, particularly those living with dementia or cognitive decline, lumbar stability work is not just about preventing back pain — it directly supports the kind of balance and postural control that reduces dangerous falls. A 2022 study in the Journal of Geriatric Physical Therapy found that adults over 65 who performed targeted core stability exercises three times per week for twelve weeks reduced their fall risk by 34 percent compared to a control group.
This matters more than most caregivers realize. Dementia often disrupts proprioception, the body’s sense of where it is in space, which means the lumbar spine has to work harder to keep the body upright during everyday movements like standing from a chair or turning in a hallway. Weak lumbar stabilizers make these transitions unpredictable and risky. The exercises outlined below are chosen specifically because they can be modified for varying ability levels, performed without equipment, and supervised safely by a caregiver at home. This article covers each exercise in detail, explains when certain movements should be avoided, and addresses the unique challenges of guiding someone with cognitive impairment through a physical routine.

Why Does Lumbar Stability Matter More for People with Dementia?
The lumbar spine is the load-bearing center of the body, and the muscles surrounding it do far more than prevent back pain. They coordinate with the hips and pelvis to keep you upright when you shift your weight, reach for something, or recover from a stumble. In healthy adults, this coordination is largely automatic. In people with Alzheimer’s disease or other forms of dementia, the neurological signals that drive this coordination degrade over time. Research from the University of Western Ontario has shown that gait instability in dementia patients correlates strongly with weakened trunk musculature, not just with the brain changes themselves. This creates a compounding problem. As someone with dementia becomes less physically active due to confusion, fatigue, or loss of motivation, the stabilizing muscles atrophy.
That atrophy leads to poorer balance, which leads to falls, which leads to hospitalization and further cognitive decline. Hip fractures in dementia patients carry a mortality rate that is roughly double that of cognitively healthy adults in the same age group. Lumbar stability exercises interrupt this cycle at its root by maintaining the muscular foundation that keeps movement safe. It is worth noting that lumbar stability is not the same as lumbar strength in the traditional sense. Doing heavy deadlifts or loaded back extensions is not the goal. Stability means the ability of small, deep muscles to fire in the right sequence at the right time. That is trainable at any age and at nearly any stage of cognitive decline, provided the exercises are appropriately selected and supervised.
The Bird Dog and Dead Bug — Two Foundational Movements
The bird dog is often the first exercise physical therapists prescribe for lumbar instability, and for good reason. From a hands-and-knees position, the person extends one arm forward and the opposite leg back, holding briefly before returning to the start. This movement forces the deep spinal stabilizers to resist rotation and extension simultaneously. For someone with moderate dementia, the movement can be simplified to just extending one leg at a time, keeping both hands planted for support. The dead bug works on the same principle but from a face-up position, which some older adults find more comfortable and less disorienting.
Lying on the back with knees bent and arms raised, the person slowly lowers one arm overhead while extending the opposite leg toward the floor. The key is that the lower back stays pressed flat against the ground throughout the movement. If the back arches, the deep stabilizers have lost control and the superficial muscles have taken over, which defeats the purpose. However, if someone has significant kyphosis — a rounded upper back common in older adults — the dead bug position may cause discomfort or breathing difficulty when lying flat. In that case, placing a thin pillow under the head and upper back can help, but if the person cannot comfortably maintain the position, the bird dog or standing alternatives are better choices. Forcing a position that causes pain or anxiety will only make the person resistant to future exercise sessions, which is a real and common problem in dementia care.
The Glute Bridge and Why Hip Strength Cannot Be Separated from Spinal Stability
The glute bridge is deceptively simple. Lying on the back with knees bent and feet flat on the floor, the person lifts the hips toward the ceiling, holds for two to three seconds, then lowers slowly. What makes this exercise essential for lumbar stability is that the gluteus maximus is the primary hip extensor, and when it is weak, the lumbar erector spinae muscles try to compensate. That compensation is one of the most common mechanical causes of lower back pain in older adults. A practical example: when someone with dementia stands up from a low chair or toilet seat, that movement should be driven primarily by the glutes and quadriceps.
If the glutes are not firing properly, the person will lean forward excessively and strain through the lower back, creating both pain and instability at the moment they are most vulnerable to falling. Glute bridges retrain this pattern in a safe, controlled environment. For individuals in later stages of dementia who may not be able to follow verbal instructions reliably, caregivers can use tactile cues. Placing a hand lightly on the person’s hip and gently guiding the movement upward can be more effective than repeated verbal explanation. A physical therapist at a memory care facility in Minneapolis documented that tactile cueing improved exercise compliance by roughly 40 percent in residents with moderate-to-severe Alzheimer’s compared to verbal instruction alone.
Side Planks and Pelvic Tilts — Choosing the Right Variation
The side plank and pelvic tilt address different aspects of lumbar stability, and choosing between them often depends on the individual’s current ability level. The pelvic tilt is the gentler option. Lying on the back, the person flattens the lower back against the floor by tightening the abdominal muscles, holds for five to ten seconds, and releases. It is subtle, nearly invisible from the outside, but it directly activates the transverse abdominis, which is the deepest layer of the core and the most important muscle for spinal stabilization. The side plank, by contrast, targets the quadratus lumborum and obliques, muscles that prevent the spine from collapsing sideways.
A full side plank on the feet is too demanding for most older adults. The modified version, performed on the knees with the elbow on the ground, is appropriate for many. Holding for even ten seconds provides meaningful stimulus. The tradeoff is that the side plank requires more balance and spatial awareness than the pelvic tilt, which can be problematic for someone with significant cognitive impairment who may not understand why they are being asked to lie on their side and hold still. For most people with early to moderate dementia, starting with pelvic tilts and progressing to modified side planks over several weeks is a reasonable approach. For those in later stages, pelvic tilts alone still provide substantial benefit and can be performed in bed, making them one of the few lumbar stability exercises that remain accessible even when mobility is severely limited.
The Cat-Cow and Modified Curl-Up — When to Use Caution
The cat-cow is a gentle spinal mobilization exercise performed on hands and knees. The person alternates between arching the back downward while lifting the head, then rounding the back upward while tucking the chin. It promotes movement through the full range of lumbar flexion and extension, which helps maintain joint health and reduces stiffness. Many people find it intuitive because it mimics a natural stretching motion, and it can be cued with simple phrases like “let your belly drop” and “round your back like a cat.” The modified curl-up is more targeted. Lying on the back with one knee bent and one leg straight, the person lifts the head and shoulders slightly off the ground while bracing the abdominals. This is not a sit-up.
The range of motion is small, just enough to activate the rectus abdominis and obliques without placing compressive load on the lumbar discs. Stuart McGill, the spine biomechanist who popularized this exercise, has emphasized that traditional sit-ups and crunches generate excessive disc pressure and should be avoided entirely in older populations. A critical warning: the modified curl-up should not be performed by anyone with osteoporosis of the thoracic or lumbar spine without clearance from a physician. The flexion load, even in this reduced form, can increase fracture risk in vertebrae that are already compromised. Since osteoporosis is common in older adults and often undiagnosed, this is not a theoretical concern. If there is any doubt, skip the curl-up and substitute additional sets of dead bugs or pelvic tilts, which provide similar muscular activation without spinal flexion.
Building a Routine That Works Within Cognitive Limitations
The biggest practical challenge is not selecting the right exercises but getting someone with dementia to perform them consistently. A routine of all seven exercises might take fifteen minutes for a cognitively healthy adult, but attempting all seven in one session with a dementia patient often leads to frustration for both the person and the caregiver. A better approach is to rotate through three or four exercises per session, three times per week, covering all seven over the course of two sessions.
One memory care occupational therapist in Portland, Oregon, found that tying exercises to existing routines dramatically improved adherence. For example, performing pelvic tilts and glute bridges immediately after waking, while the person is already lying in bed, removes the barrier of getting down to the floor. Cat-cow can be performed before breakfast as part of a “morning stretch.” Framing these movements as part of daily life rather than as an exercise program sidesteps the resistance that many people with dementia feel toward structured activities that feel unfamiliar or demanding.
What Emerging Research Suggests About Exercise and Cognitive-Motor Decline
A growing body of evidence suggests that the relationship between lumbar stability and cognitive function may be bidirectional. A 2024 longitudinal study published in Neurology found that older adults who maintained trunk muscle strength over a five-year period showed slower rates of hippocampal volume loss compared to those whose trunk strength declined. The mechanism is not fully understood, but researchers believe it may relate to the sustained neurological demand of postural control — the brain regions involved in balance and coordination overlap significantly with those affected early in Alzheimer’s disease.
This does not mean that lumbar exercises prevent dementia. That would be an overstatement of the current evidence. But it does suggest that maintaining physical stability has cognitive benefits beyond fall prevention, and that the investment in a simple, consistent exercise routine pays dividends that extend further than most caregivers expect. As dual-task training protocols — exercises that combine physical movement with cognitive challenges — continue to be refined, lumbar stability work is likely to become a standard component of comprehensive dementia care plans rather than an afterthought.
Conclusion
Lumbar stability is one of the most practical and impactful areas of physical health that caregivers can address. The seven exercises described here — bird dog, dead bug, glute bridge, side plank, pelvic tilt, cat-cow, and modified curl-up — require no equipment, can be adapted to a wide range of ability levels, and directly target the muscular weakness that makes falls so dangerous for people with dementia. The key is not perfection in form but consistency in practice, performed in short sessions that fit within the person’s daily routine and cognitive capacity. If you are caring for someone with dementia and they are not currently doing any structured movement, start with just two exercises: the pelvic tilt and the glute bridge. Both can be done in bed.
Both are safe for nearly everyone. Once those become familiar, add one new exercise every week or two. Consult a physical therapist who has experience with neurodegenerative conditions if possible, as they can tailor the program and identify contraindications that a general guide cannot. The goal is not to build an athlete. The goal is to keep someone safe, mobile, and as independent as their condition allows for as long as possible.
Frequently Asked Questions
Can someone with advanced dementia still do lumbar stability exercises?
Yes, though the selection narrows significantly. Pelvic tilts and glute bridges can be performed in bed with caregiver assistance and tactile cueing. The person does not need to understand the purpose of the exercise for the muscles to benefit from the movement. Even passive range-of-motion work, where the caregiver moves the person’s limbs, provides some benefit to joint health and circulation.
How often should these exercises be performed?
Three times per week is the most commonly supported frequency in the research. Daily performance is not harmful for most of these exercises, but it can increase caregiver burden and patient resistance. Consistency over weeks and months matters far more than daily frequency.
Are these exercises safe for someone with spinal stenosis?
Most of them are, but exercises that involve lumbar extension — such as the downward arch phase of cat-cow — can worsen symptoms of spinal stenosis by narrowing the spinal canal further. People with diagnosed stenosis generally tolerate flexion-based exercises like pelvic tilts and dead bugs better. A physician or physical therapist should guide the selection.
What if the person refuses to exercise or becomes agitated?
This is common and not a failure. Forcing compliance creates negative associations that make future attempts harder. Try again at a different time of day, use music the person enjoys as a backdrop, or reframe the movement as a game or familiar activity rather than exercise. Some caregivers have success performing the exercises alongside the person, which leverages the mirroring instinct that often remains intact even in moderate dementia.
Should lumbar exercises replace walking or other aerobic activity?
No. They serve different purposes. Walking and aerobic activity support cardiovascular health and have their own cognitive benefits. Lumbar stability exercises specifically address the muscular control needed to make walking and other activities safer. The two are complementary, not interchangeable.
