Neck and Back Injury Healing Stages: Inflammation to Recovery

Can knowing the characteristics of each stage of healing help expedite recovery for individuals who are healing after neck and back injuries?

Back or Neck Injury Healing Stages

At each stage, different things happen at the injury site. This means recommended exercises and activity levels will vary depending on how long it’s been since the injury. The stages to know about when healing from a neck or back injury. (Brumitt J., and Cuddeford T. 2015)

Inflammation or Acute Stage

Also known as the inflammatory stage, the acute stage occurs during the injury and can continue for 72 hours. The body releases repair chemicals in response to tissue damage, causing inflammation and pain. Symptoms of inflammation, including redness, swelling, pain at rest, and diminished function, are expected. Inflammation and pain during the inflammation stage are caused by the body’s repair chemicals released in response to tissue damage. (Wu, Y. S. and Chen S. N. 2014) The biological reaction decreases mobility so the injured area can rest and heal, but the substances that promote healing also cause pain and swelling. (Shah A. and Amini-Nik S. 2017) Scar tissue also begins to form during the inflammatory stage. (Wilgus T. A. 2020) Initial treatment focuses on reducing pain, swelling, and muscle spasms. Individuals are encouraged to use ice packs, compression, and over-the-counter anti-inflammatory medications like ibuprofen or naproxen. (Duchesne E., Dufresne S. S., and Dumont N. A. 2017)

Subacute Stage

Inflammation decreases, and new connective tissue and capillaries grow to help repair damaged structures. The subacute phase generates new connective tissue and capillary growth and reduced inflammation. (Brumitt J., and Cuddeford T. 2015) Scar tissue continues to grow during this time, as well. The tissues are still fragile at this stage, stressing the injured area should be limited to when the therapist or doctor is examining or working with the patient. Most physical therapists recommend beginning with gentle movement during the subacute phase and gradually building up the intensity of exercise. Mild isometric and low-intensity exercises are often used. Because activity is restricted, the muscles may seem weak. Depending on the severity of the injury and the type of tissue that was injured (i.e., tendons have less blood circulation and tend to heal more slowly, it can take a few days to several weeks. (Brumitt J., and Cuddeford T. 2015)

The Chronic Stage or Maturation

The inflammation disappears entirely during the chronic or maturation stage of neck or back injury healing. The new collagen fibers build strength, and the wound shrinks. (Brumitt J., and Cuddeford T. 2015) During this stage, pain associated with the injury tends to be limited to the end joint’s range of motion. The first ten weeks of the chronic stage are essential for engaging in exercises that enhance healing and help remodel the fibers so they will function as close as possible to the way they did before the injury. (Azevedo P. S. et al., 2016) Exercises during the ten weeks are important because otherwise, individuals can permanently lose some of their ability to move and function.

After around ten weeks, the scar tissue can permanently change, so re-acquiring strength and flexibility may necessitate surgery or manual release treatment from a physical therapist or chiropractor. During this time, the scar tissue can be remodeled with exercise, meaning that the activities and motions performed on the injured area will affect the formation of new tissue fibers. The chronic stage of healing begins after 21 days and doesn’t end after the 10-week prime time (Brumitt J., and Cuddeford T. 2015). It can continue for quite some time.

Treatment

Treatment focuses on engaging the injured muscles in light isometric contractions to help align new collagen fibers. Physical therapy helps rebuild mobility, strength, balance, and flexibility and can also help learn about injury and how to recover. A treatment that may also help during these phases is massage therapy. Extended bed rest or immobility can prolong symptoms and delay recovery. Tips to manage pain and recovery:

• When sitting for long periods, get up and move around frequently.
• Wear comfortable shoes.
• When driving long distances, stop frequently to stand up and walk around.
• Sleep on the side with a small pillow between the knees.
• Limit how much weight is carried.
• Add exercises gradually.

Most symptoms of back strain or sprain improve in about two weeks. Individuals may need additional treatment if symptoms continue for longer than two weeks. Maintaining exercises will continue to make the body stronger, more flexible, more functional, and pain-free.
