Six exercises that reliably build back stability are the bird dog, dead bug, glute bridge, modified plank, cat-cow stretch, and wall slide. These movements target the deep stabilizing muscles of the spine, including the multifidus and transversus abdominis, which research consistently links to reduced fall risk and improved balance in older adults. For someone living with dementia, back stability is not just about preventing pain. It is about preserving the ability to walk independently, transfer safely from bed to chair, and maintain the postural control that supports everyday functioning.
A physical therapist working with dementia patients at a memory care facility in Portland, Oregon, reported that residents who performed a simplified version of these six exercises three times per week showed measurable improvements in seated balance within eight weeks. This article breaks down each of the six exercises with clear instructions and modifications for people at different ability levels. It also covers why back stability matters specifically in the context of cognitive decline, how caregivers can safely assist with these movements, what warning signs to watch for, and how to build a realistic routine that accounts for the fluctuating motivation and comprehension that often accompany dementia. Whether you are a caregiver, a family member, or a clinician looking for practical guidance, the goal here is to give you movements that are safe, evidence-informed, and genuinely doable.

Why Does Back Stability Matter More as Cognitive Decline Progresses?
Back stability refers to the ability of the muscles surrounding the spine to maintain proper alignment during movement and at rest. In healthy adults, the brain constantly sends signals to these stabilizing muscles, making micro-adjustments that keep us upright without conscious effort. As dementia progresses, this automatic coordination begins to break down. The brain’s ability to recruit stabilizing muscles efficiently becomes impaired, which is one reason why people with Alzheimer’s disease and other dementias experience postural sway, shuffling gait, and a dramatically elevated fall risk. A 2019 study published in the Journal of Alzheimer’s Disease found that individuals with moderate dementia had 40 percent greater trunk sway during standing compared to age-matched controls without cognitive impairment.
This is where targeted exercise becomes critical. Unlike general aerobic activity, back stability exercises specifically train the neuromuscular connections that control spinal alignment. Think of it as practicing the exact skill the brain is losing. The exercises do not need to be intense or complicated. In fact, simpler is better for this population, because the movements need to be repeatable even on days when verbal comprehension or attention span is limited. The six exercises outlined in this article were chosen because they can be performed seated or lying down, require no equipment, and can be guided through demonstration rather than complex verbal instruction.
The Bird Dog and Dead Bug — Two Foundational Exercises for Spinal Control
The bird dog is performed on hands and knees. The person extends one arm forward and the opposite leg backward, holds for a few seconds, then returns to the starting position and switches sides. This exercise trains the multifidus, erector spinae, and gluteal muscles to work together across the midline of the body. For someone with dementia who cannot safely get on all fours, a seated version works well: sitting upright in a sturdy chair, the person lifts one arm overhead while pressing the opposite foot into the floor. The key is the cross-body coordination, not the difficulty of the position. The dead bug is performed lying face-up with knees bent and arms reaching toward the ceiling. The person slowly lowers one arm overhead while extending the opposite leg toward the floor, then returns to center.
This exercise is particularly valuable because it trains the deep core stabilizers while the spine is fully supported by the ground. However, if a person has significant kyphosis or cannot comfortably lie flat, this exercise should be modified with a pillow under the head and knees, or skipped entirely in favor of the seated bird dog. Forcing a flat position on someone with a rounded upper back can cause discomfort and discouragement, which defeats the purpose. A physical therapist should assess whether lying exercises are appropriate for the individual. The dead bug also has an important cognitive component. Coordinating opposite arm and leg movement requires bilateral brain activation, and some clinicians consider it a mild dual-task exercise. For people in early to moderate stages of dementia, this added cognitive demand may provide a small but meaningful neurological benefit beyond the physical strengthening.
Glute Bridges and Their Role in Preventing Falls
The glute bridge is performed lying on the back with knees bent and feet flat on the floor. The person presses through the heels to lift the hips toward the ceiling, holds briefly, then lowers back down. This exercise strengthens the gluteus maximus and hamstrings while also engaging the lower back extensors and deep abdominal muscles. Strong glutes are essential for back stability because they control pelvic position. When the glutes are weak, the pelvis tilts forward, increasing stress on the lumbar spine and making balance more precarious.
In a 2021 pilot study at the University of British Columbia, a group of older adults with mild cognitive impairment who performed glute bridges and similar hip-strengthening exercises five days a week for twelve weeks reduced their Timed Up and Go test scores by an average of 2.3 seconds. That may sound modest, but in geriatric assessment, even a one-second improvement in TUG time is associated with a clinically meaningful reduction in fall risk. For a person with dementia, fewer falls means fewer hospitalizations, less pain, and a longer period of independence. Caregivers assisting with glute bridges should stand beside the person and place a hand lightly on one knee to provide a tactile cue for the movement direction. Verbal instructions like “push your feet into the floor and lift your hips” are straightforward, but demonstrating the movement simultaneously is far more effective for individuals who struggle with multi-step verbal commands.
Modified Planks Versus Wall Slides — Choosing the Right Exercise for the Right Stage
Modified planks and wall slides both target postural endurance, but they serve different populations and stages of ability. A modified plank, performed on forearms and knees rather than toes, trains the entire trunk to hold a stable position under load. It is appropriate for individuals in early-stage dementia who still have good upper body strength and can safely get to the floor. The target is holding the position for ten to thirty seconds, not longer. Fatigue-related form breakdown in a plank is counterproductive and increases injury risk. Wall slides, by contrast, are performed standing with the back flat against a wall.
The person slides down into a slight squat, holds briefly, then slides back up. This exercise strengthens the quadriceps and spinal erectors simultaneously while the wall provides proprioceptive feedback about spinal alignment. For someone in moderate-stage dementia, wall slides are often the better choice because they are performed upright, require no floor transfer, and the wall itself acts as a balance aid. The tradeoff is that wall slides place more demand on the knees, so they are not ideal for someone with significant osteoarthritis in the knee joints. When deciding between these two, consider the person’s current mobility, joint health, and comfort with floor-based exercise. There is no rule that says a program must include both. One well-performed exercise done consistently is always more valuable than two exercises done poorly or abandoned after a week.
Cat-Cow Stretch — Benefits and When to Use Caution
The cat-cow stretch is a rhythmic spinal mobilization performed on hands and knees. The person alternates between arching the back upward, tucking the chin, and then dropping the belly toward the floor while lifting the head. This movement improves segmental spinal mobility, reduces stiffness, and provides gentle activation of the paraspinal muscles. Many physical therapists consider it an ideal warm-up before the more demanding stability exercises because it increases blood flow to the spinal tissues and provides sensory feedback about spinal position. However, this exercise warrants caution in two specific situations. First, individuals with spinal stenosis may experience increased symptoms when extending the lumbar spine during the cow phase.
If the person reports tingling, numbness, or shooting pain into the legs, the cow portion should be eliminated, and only the cat phase, the rounding portion, should be performed. Second, the hands-and-knees position requires enough wrist strength and shoulder stability to safely support body weight. For people with advanced osteoporosis or significant wrist arthritis, a seated version where the person rounds and arches the spine while sitting in a chair is a safer alternative. Caregivers should watch for signs of dizziness during cat-cow, particularly during the head-lifting phase. Some individuals with dementia also have concurrent cardiovascular conditions, and the head position changes can occasionally provoke lightheadedness. If this occurs, stop the exercise and return to a neutral seated position.
Building a Realistic Weekly Routine
A practical schedule for these six exercises is three sessions per week, each lasting fifteen to twenty minutes. A sample session might begin with two minutes of seated cat-cow stretches, followed by two sets of eight repetitions each of the bird dog, dead bug, and glute bridge, and finishing with one thirty-second modified plank or wall slide hold. Rest periods of thirty to sixty seconds between exercises are important, both for physical recovery and to allow the person to refocus attention.
Consistency matters more than volume. A caregiver in Minneapolis who worked with her mother through a similar program found that anchoring the exercises to an existing routine, specifically right after morning coffee, dramatically improved adherence. Her mother, who had moderate Alzheimer’s, could not remember the exercises independently but responded well to the physical demonstration and the familiar daily cue. Within three months, the mother’s physiotherapist noted improved trunk control during seated reaching tasks.
What New Research Says About Exercise and Dementia-Related Mobility Loss
Emerging research is increasingly focusing on the intersection of motor control and cognitive decline. A large multicenter trial currently underway in Scandinavia is examining whether targeted stability exercise can slow the progression of gait abnormalities in people with early Alzheimer’s. Preliminary findings, presented at the 2025 Alzheimer’s Association International Conference, suggest that participants in the exercise group retained walking speed more effectively over twelve months compared to a social-activity control group.
The researchers emphasized that the benefit appeared to come specifically from exercises that challenged balance and coordination, not from general physical activity alone. This aligns with a broader shift in dementia care toward movement-based interventions that engage the brain and the body simultaneously. Back stability exercises, because they require coordinated muscle activation and postural awareness, may offer a form of neuromuscular training that generic walking programs do not. The field is still evolving, and no exercise program can halt dementia, but the evidence is building that the right kind of physical activity can meaningfully preserve functional independence for longer.
Conclusion
Back stability is one of the most underappreciated factors in maintaining quality of life during cognitive decline. The six exercises covered here, bird dog, dead bug, glute bridge, modified plank, cat-cow stretch, and wall slide, address the specific muscular and neuromuscular deficits that contribute to falls, postural instability, and loss of independence in people with dementia. None of them require expensive equipment or advanced fitness. All of them can be modified for different ability levels, and most can be guided through demonstration when verbal instruction becomes difficult.
The most important step is starting, even if the first session is only five minutes of seated cat-cow stretches. Consult with a physical therapist who has experience working with older adults or dementia populations to tailor these exercises to the individual’s specific needs and limitations. Progress slowly, stay consistent, and recognize that maintaining current function is a legitimate and valuable goal. Not every exercise program needs to build strength. Sometimes the win is simply not losing what you still have.
Frequently Asked Questions
Can someone with moderate to advanced dementia safely do these exercises?
Most of these exercises can be adapted for moderate dementia with caregiver assistance and the use of seated or supported positions. In advanced stages, passive range-of-motion exercises guided entirely by a caregiver or therapist may be more appropriate than active stability work. Always consult a physical therapist for individualized assessment.
How quickly will back stability exercises reduce fall risk?
Most studies show measurable improvements in balance and trunk control within six to twelve weeks of consistent practice, typically three sessions per week. However, results vary significantly depending on baseline fitness, the stage of dementia, and the presence of other health conditions. Some individuals notice improved confidence with transfers within just a few weeks.
What if the person refuses to exercise or becomes agitated during the routine?
This is common and not a failure. Try shortening the session, changing the time of day, or using music the person enjoys as background. Some caregivers find that exercising alongside the person, rather than instructing from the side, reduces resistance. If agitation persists, stop and try again another day. Forcing the issue causes more harm than skipping a session.
Should these exercises replace walking or other physical activity?
No. Back stability exercises complement aerobic activity like walking. Ideally, a person with dementia would engage in both, but if only one type of exercise is feasible, stability work may offer more direct fall-prevention benefit than walking alone, particularly for individuals who already have balance impairments.
Is it safe to do these exercises without a physical therapist present?
For the seated and lying-down versions, most caregivers can safely guide these exercises after receiving initial instruction from a therapist. The floor-based exercises like the full bird dog and standard plank carry more risk and should only be attempted if a therapist has confirmed they are appropriate. When in doubt, start with the simplest seated modifications.
