We hear the words sprain and strain quite often when it comes to injuries. Whilst they sound similar, they refer to two different tissue types that are damaged resulting in changes in the recovery period and treatment. Here, we will explain the differences between each injury, their symptoms, and how physiotherapy can aid in the recovery process.
What is a Strain?
A strain refers to an injury that occurs to a muscle or tendon (the tissue connecting in the muscle to bone) when it is stretched or torn. Generally, this can occur when the muscle is stretched too far quickly, or under excessive load. For example, when going to sprint, kicking, and heavy lifting.
Symptoms of a strain:
• Pain in the affected muscle or tendon
• Potentially swelling and bruising around the injury site
• Limited range of motion
• Muscle weakness
• Muscle spasms
Strains can be graded to demonstrate the severity of the injury and can aid in the understanding of healing time frames.
Grade l: small number of muscle fibers affected, localised pain, but no loss of strength
Grade ll: significant number of muscle fibers with associated pain and swelling. Activation of the muscle reproduces pain, strength and range of motion is limited.
Grade lll: complete tear of the muscle.
A number of factors can be looked at to prevent strains - head over to our injury prevention tip and tricks blog to read more.
What is a Sprain?
A sprain refers to an injury that occurs to a ligament (the connective tissue stabilising bones together). A sprain to a ligament generally occurs when a joint is forced beyond its normal range of motion. For example, ‘rolling’ your ankle, landing awkwardly from a jump, or an excessive twisting motion potentially increased by another person (i.e in sport).
Symptoms of a Sprain:
• Pain around the affected joint
• Swelling and bruising around the joint
• Limited mobility and difficulty moving the joint / instability in the joint
• In more severe cases, feeling of “giving way”
Sprains too can be graded to understand the severity of the injury, aiding in the understanding of healing periods.
Grade l: stretch of a few fibers of the ligament
Grade ll: considerable proportion of fibers involved resulting, in slight laxity of the joint
Grade lll: complete tear of the ligament.
How Physiotherapy Can Help
In the acute stages of a strain or sprain a physiotherapist can aid you understand which injury it is that you have and apply the P.R.I.C.E principals to reduce swelling and pain. Following from this physiotherapists can conduct a number of tests to understand your grade of injury, capabilities, and limitations to aid in your restoration of mobility, strength, and stability. This can be through stretching, strengthening, joint mobilisations, balance and coordination exercises, manual therapy, and much more.
Feel free to contact us if you have any questions or feel like an appointment with a physiotherapist would suit you.
Understanding Corticosteroid Injections: Benefit vs Risk
Corticosteroid injections have become a common treatment option for a variety of musculoskeletal conditions, particularly for those experiencing pain and inflammation. However, it is important to understand how these injections work, their benefits, risks, and how they can fit into a broader holistic rehabilitation strategy.
What Are Corticosteroids?
Corticosteroids are synthetic drugs that closely resemble cortisol, a hormone produced by the adrenal glands. With the synthetic form, it attempts to mimic the effects of the cortisol our body produces such as, reducing inflammation, suppressing the immune response, and alleviating pain.
Injections are often used to target specific areas of the body, such as joints, bursae, or tendons.
Indications for Corticosteroid Injections
Corticosteroid injections can be used for various conditions, including:
• Arthritis: Osteoarthritis and rheumatoid arthritis often lead to significant joint pain and stiffness.
• Tendinopathies: persistent tendinopathies where inflammation may be present, e.g lateral elbow tendinopathy, aka tennis elbow
• Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion bones, muscles, and tendons.
• Other inflammatory conditions: Conditions like carpal tunnel syndrome or certain skin disorders can also be treated with corticosteroids.
The Benefits of Corticosteroid Injections
One of the primary advantages of corticosteroid injections is their ability to provide rapid relief from inflammation and pain. Patients often experience significant improvement within a few days, allowing them to engage more actively in rehabilitation exercises and daily activities.
Additionally, corticosteroid injections can be combined with physiotherapy to enhance recovery. By alleviating pain, these injections can provide a window of opportunity for patients to more readily participate in their rehabilitation program, ultimately leading to better long-term outcomes.
Risks and Considerations
While corticosteroid injections can be effective, there are several risks and considerations to keep in mind:
• Side Effects: Possible side effects include temporary pain at the injection site, bruising, and in some cases, infection. Long-term use can lead to systemic effects such as osteoporosis and adrenal suppression.
• Potentially short-term relief: The length of time that it provides pain relief can vary significantly between clients. It is common for people not to feel any effect after the injection whilst others may have a positive effect for months.
• Limitations on Frequency: To avoid complications, corticosteroid injections are typically limited to a certain number per year (often three to four). Overuse can lead to joint damage or other adverse effects due to high steroid use.
• Not a Cure: It's essential to understand that corticosteroid injections are not a cure for the underlying condition. They provide symptomatic relief but do not address the root cause of pain or inflammation.
Integrating Corticosteroid Injections into Rehabilitation
As a physiotherapist, these are the steps that we could follow to help guide you if you should get an injection and the steps if you choose to get one.
1. Assessment: a thorough assessment helps determine the appropriateness of corticosteroid injections. We evaluate the patient’s condition, pain levels, and functional limitations. We will try a period of time with treatment to see if we can get any changes without the injection prior.
2. Post-Injection Rehabilitation: After the injection, a tailored rehabilitation program is essential. This program may include manual therapy, strengthening exercises, and modalities to improve function and reduce pain.
3. Education: Patients are educated on the purpose and potential side effects of the injections, as well as the importance of active participation in their rehabilitation.
4. Monitoring Progress: follow-ups to help track the effectiveness of the injections and the rehabilitation program. Adjustments can be made as needed to optimize recovery.
To opt for it or not to?
Ultimately, that will be based on you and your conversations and directions provided by medical and allied health clinicians. Corticosteroid injections can be a valuable tool in managing pain and inflammation in musculoskeletal conditions especially for conditions which seem to be persisting. Again to provide clients with a window to strengthen the muscles and surrounding tissues to allow for long-term relief. However, it is important to understand the variations of success people receive from them and the potential side-effects.
If you are suffering from an injury or niggle which is not going away and are querying whether a corticosteroid injection is what you need, contact one of our physiotherapists and we will be more than happy to help guide you.
