Feeling Unsteady? How Muscle Strength and Spinal Mobility Support Your Balance

Sep21st 2026

You pause before stepping off a curb, or  reach for the counter when you turn. Getting out of a low chair takes more effort than it used to.

These changes deserve attention, even if you have never fallen.

Your leg and hip muscles help support your weight and move you from one step to the next. Your trunk muscles help control your upper body. Spinal mobility allows you to bend and turn during everyday movement.

Balance also involves vision and the inner ear’s vestibular system. Muscle weakness and limited joint movement are other possible contributors. An PinPoint Evaluation helps determine which factors need attention. 

For adults in Evanston and Chicago’s North Shore, that evaluation can begin with a practical question: Which movements have started to feel less secure with?

How leg and hip strength support your balance

Think about stepping onto a curb. One leg lifts while the other supports your body. As your weight moves forward, your muscles must control the transfer.

Several muscle groups share that work:

  • Your thighs help straighten your knees when you stand up or climb stairs. They also help control lowering into a chair.
  • Your gluteal muscles help extend your hips and steady your pelvis while you step.
  • Your calf and ankle muscles help you push off, control your foot position, and make small adjustments while standing.

Weakness can make these tasks more demanding. You might push harder through your arms to get out of a chair or hesitate when shifting your weight onto one leg.

Strengthening exercises can improve balance, but balance practice matters too. Federal health guidance recommends that older adults include both types of activity, along with aerobic activity and flexibility work.

How trunk control and spinal mobility help you turn

Your trunk includes your abdomen, back, and the muscles around your pelvis. These muscles help manage the position of your upper body as your arms and legs move.

For example, reaching into a cabinet shifts your weight. Turning to place a grocery bag on the counter requires your feet, hips, and trunk to work together.

Spinal mobility is your ability to move through your back and neck. Comfortable movement helps you look around, reach, and change direction. If turning feels stiff or painful, you may change how you perform those tasks.

That does not prove your spine is causing your unsteadiness. Your therapist needs to examine whether a movement restriction actually affects the activities you find difficult.

The goal is enough movement and control for your daily tasks. You do not need to force a larger twist or hold your back rigidly upright.

What a physical therapist evaluates for balance problems

Be specific about what happens. “I feel unsteady when I turn away from the sink” gives your therapist more useful information than “My balance is bad.”

Bring up near-falls, changes in walking, and activities you have started avoiding. Mention dizziness, numbness, medication changes, and any recent falls as well.

Your assessment may include leg strength, joint movement, coordination, walking, and balance. The therapist may also recommend further medical assessment when the findings suggest another contributor.

Common functional tests include:

  • A chair stand test to assess leg strength and endurance.
  • Standing in different foot positions to assess balance.
  • The Timed Up and Go test, which examines mobility while getting up, walking, turning, and sitting down.

These are among the tools in the CDC’s STEADI fall prevention program. They provide measurable starting points that can help track change.

How treatment supports everyday movement

Treatment should connect the examination findings to the activity you want to do more comfortably.

If getting out of a chair is difficult, your plan may include progressively challenging sit-to-stand practice. If stepping sideways feels uncertain, treatment may include hip strengthening and supported stepping. If stiffness limits turning, your therapist may address that restriction and practice turning with you.

Balance rehabilitation can also include trunk strengthening, reaching, weight shifts, and walking tasks. Exercises progress as your ability improves.

A useful treatment goal is specific: turning in your kitchen without grabbing the counter, managing the steps at your front door, or feeling more secure on your usual walk.

Ask your therapist how each exercise supports that goal and how you will measure progress. Home practice should match your current ability and include support when needed.
