Locomotor System Care in Grand Rapids, MI

The locomotor system, also called the musculoskeletal system, includes your bones, joints, muscles, tendons, ligaments, cartilage, and other connective tissues. In Grand Rapids, MI, keeping this system healthy is especially important for staying active through snowy winters, icy sidewalks, and busy outdoor summers along the Grand River and West Michigan trails.

Local healthcare systems such as Corewell Health (formerly Spectrum Health), Trinity Health Grand Rapids, Metro Health – University of Michigan Health, and Mercy Health offer specialized orthopedic and sports medicine services to help diagnose and treat locomotor system conditions.


What Is the Locomotor (Musculoskeletal) System?

The locomotor system is the part of your body that:

  • Supports your body’s weight
  • Protects your internal organs
  • Allows you to move, walk, run, lift, and perform daily activities

It is made up of:

  • Skeleton (bones)
  • Skeletal muscles
  • Tendons (attach muscle to bone)
  • Ligaments (connect bone to bone)
  • Joints (where bones meet)
  • Cartilage (smooth tissue that cushions joints)
  • Other connective tissues

In Grand Rapids, many residents rely on a healthy locomotor system for work in manufacturing, healthcare, construction, and for recreational activities like biking, skiing, and hiking in West Michigan.


How the Locomotor System and Brain Work Together

Movement Is Controlled by the Brain

The brain and nervous system control all voluntary movement. They use information from:

  • Muscles and joints (often called “muscle sense” or kinaesthesia)
  • Nerves that send signals about position, pressure, and pain

This feedback allows you to walk on icy sidewalks in winter, climb stairs at work, or shovel snow without constantly watching every step.


The Skeleton: Structure, Support, and Protection

Bones are a type of connective tissue reinforced with calcium and bone cells. Inside many bones is a softer center called bone marrow, where blood cells are produced.

Main Functions of the Skeleton

The skeleton has three major functions:

  1. Support

    • Keeps your body upright
    • Provides a framework for muscles and organs
  2. Shape

    • Gives the body its form
    • Allows an upright posture, which would be impossible without the spine
  3. Protection

    • Skull protects the brain
    • Ribcage protects the heart and lungs
    • Spine protects the spinal cord

In addition, the skeleton:

  • Stores minerals such as calcium and phosphorus
  • Stores lipids (fats) in bone marrow
  • Produces blood cells (red blood cells, white blood cells, and platelets)

For Grand Rapids residents, especially older adults, maintaining healthy bones is essential to lower the risk of fractures from winter falls and icy conditions.


Muscles: How Your Body Moves

Types of Muscles

There are two main types of muscles important for understanding the locomotor system:

  • Skeletal muscles (voluntary muscles)

    • Attach to bones
    • Operate under voluntary control – you consciously decide to move them
    • Example: muscles used to walk, lift, or exercise at a local Grand Rapids gym
  • Smooth muscles (involuntary muscles)

    • Found in organs such as the digestive system and blood vessels
    • Work automatically, without conscious control
    • Example: muscles that move food through the intestines

How Skeletal Muscles Are Built

Skeletal muscles are made up of many muscle fibers bundled together.

  • Each muscle fiber can contract (shorten) or relax (lengthen) on demand.
  • When all fibers in a muscle contract together, the muscle shortens and pulls on the bone it is attached to, creating movement.

How Muscles and Joints Work Together

Muscle Contraction and Nerves

The brain sends signals through nerves to tell muscles when to contract or relax. This is how you:

  • Bend and straighten your arms
  • Walk on uneven sidewalks downtown
  • Climb stairs at work or at home
  • Participate in local sports and recreation

Muscles Often Work in Pairs

Most skeletal muscles work in opposite pairs, meaning one muscle contracts while the other relaxes.

Example: Bending and Straightening the Elbow

  • To bend your elbow:

    • Biceps (front of upper arm) contract
    • Triceps (back of upper arm) relax
  • To straighten your elbow:

    • Triceps contract
    • Biceps relax

In complex joints like the shoulder, many different muscles attach to the joint. This allows:

  • A wide range of motion
  • The ability to reach overhead, lift groceries, or play sports like basketball or tennis at local Grand Rapids facilities

Common Locomotor System Problems in Grand Rapids, MI

Residents of Grand Rapids and West Michigan may experience a range of musculoskeletal conditions, often influenced by:

  • Cold, icy winters (falls, slips, and fractures)
  • Physically demanding jobs (manufacturing, construction, healthcare)
  • Repetitive motion (office work, assembly lines, computer use)

Some common locomotor system problems include:

Osteoporosis

Osteoporosis is a condition where bones lose minerals such as calcium faster than the body can replace them. As a result, bones:

  • Become less dense
  • Lose strength
  • Break more easily, especially in the hip, spine, or wrist

Osteoporosis is more common in older adults and postmenopausal women. In Grand Rapids, bone health screenings and treatment are available through local health systems and clinics.

Bone Fractures

Bone fractures are often caused by:

  • Falls on ice or snow during Michigan winters
  • Sports injuries
  • Motor vehicle accidents
  • Work-related injuries

Fractures may require:

  • Casting or bracing
  • Surgery
  • Physical therapy at local rehabilitation centers in Grand Rapids

Arthritis and Inflammatory Joint Disease

Arthritis is an inflammatory disease affecting the joints. It can cause:

  • Joint pain
  • Swelling
  • Stiffness
  • Reduced range of motion

Types include:

  • Osteoarthritis (wear-and-tear arthritis, common in knees, hips, and hands)
  • Rheumatoid arthritis (autoimmune inflammatory arthritis)

Arthritis can also affect other areas of the body, including:

  • Eyes
  • Skin
  • Other organs

Grand Rapids residents can access rheumatology and orthopedic specialists through Corewell Health, Trinity Health Grand Rapids, and other local providers.

Back and Neck Pain

Back and neck pain are very common in Kent County and across Michigan. Causes include:

  • Poor posture (especially with prolonged computer or phone use)
  • Heavy lifting at work or home
  • Degenerative changes in the spine
  • Previous injuries or car accidents

Local physical therapy, chiropractic care, and pain management services in Grand Rapids can help manage these conditions.

Overuse and Mechanical Injuries

These injuries often result from repetitive movements or sudden strain, and include:

  • Tendonitis – inflammation of a tendon
  • Muscle strains – overstretching or tearing of muscle fibers
  • Ligament sprains – stretching or tearing of ligaments around joints

They are common in:

  • Athletes (running, basketball, hockey, skiing)
  • Workers with repetitive tasks
  • People starting new exercise routines without proper conditioning
