Sports Injury

What is Sports Injury?

A sports injury is damage to the body's muscles, ligaments, tendons, bones or joints that happens during sport or exercise. Acute injuries, such as a sprained ankle, follow a single event. Overuse injuries build up when repeated loading exceeds what the tissue can adapt to.^{[1, 2]}

Common symptoms

Pain is the most common symptom, often with swelling, bruising and stiffness. Acute sprains set off an inflammatory response with pain, swelling and a feeling of instability in the joint.^[2]

• Pain that starts after activity and later continues at rest, which can signal a bone stress injury^[1]
• Loss of strength or range of motion
• A joint that gives way or will not bear weight
• Soreness a day or two after unusual exercise, often called delayed-onset muscle soreness

Causes and risk factors

Injuries come from sudden force, from overload, or from both. Ankle sprains, for example, occur when twisting forces exceed the strength of the ligaments. Risk factors for ankle sprain include a previous sprain, poor balance and joint position sense, inadequate warm-up, unsuitable footwear and uneven surfaces.^[2] Hamstring strains typically happen with fast running or with the leg stretched far forward.^[3] Bone stress injuries tend to follow a rapid increase in training volume or intensity.^[1]

How it is diagnosed and treated conventionally

A clinician diagnoses a sports injury from the history and a physical examination, and uses imaging such as X-ray or MRI when a fracture, tendon tear or bone stress injury is suspected.^[1] Care for a sprain usually follows the POLICE approach (protection, optimal loading, ice, compression, elevation), with early guided movement preferred over long immobilization.^[2]

An overview of 46 systematic reviews found strong evidence for anti-inflammatory drugs and early mobilization after an acute ankle sprain, with moderate evidence for exercise and manual therapy.^[4] Surgery is generally kept for severe injuries or lasting instability.^[2]

Why Sports Injury calls for a whole-person approach

Most sports injuries involve more than one factor: the force of the event, the condition of the tissue, training habits and recovery. Recovery usually works best when pain is managed while strength, movement and training load are also addressed.

Complementary care may help with comfort during that process, but it does not replace rehabilitation.

Training load and strength

Strength training is among the best-supported ways to prevent injury. A meta-analysis of six trials in 7,738 participants found that strength training programs cut sports injuries to roughly a third of the control rate.^[5]

Previous injury and joint control

A past sprain, poor balance and ligament laxity raise the risk of another sprain. Bracing and neuromuscular training reduce recurrence.^{[2, 4]}

Inflammation and tissue healing

Inflammation is part of the normal early response to injury.^[2] Laboratory studies of acupuncture and electroacupuncture in inflammatory pain suggest that these treatments may act on immune cells, nerve signaling and the body's own opioid system, although this has been studied mostly in animals.^{[6, 7]}

Muscle soreness and recovery

Hard or unfamiliar exercise can cause delayed-onset muscle soreness and a rise in blood markers of muscle damage such as creatine kinase.^{[8, 9]} Recovery after training is a reasonable target for supportive care.

Acupuncture for Sports Injury

What the research shows

The evidence for acupuncture in sports injuries is limited and mostly low in quality. There are no large, high-quality trials across sports injuries as a group, so the research is for specific problems.

For acute ankle sprain, a meta-analysis of 17 trials with 1,820 participants found that more people reported symptom improvement with acupuncture than without. The authors judged the trials generally poor in quality, likely overestimating the benefit, and concluded the evidence was insufficient to recommend acupuncture as an evidence-based option.^[10] A 2020 meta-analysis of 17 trials found acupuncture reduced pain more than rest, ice, compression and elevation alone, with no difference in ankle function score, and also called for larger, better-designed trials.^[11] An overview of systematic reviews described the evidence for acupuncture in acute ankle sprain as conflicting.^[4]

For delayed-onset muscle soreness, a meta-analysis of six trials found lower soreness ratings and lower creatine kinase after acupuncture.^[8] Another review of five trials in 182 healthy volunteers found conflicting to limited evidence, with risk of bias in all of them.^[12]

How acupuncture may work

Researchers propose that acupuncture and electroacupuncture ease pain by activating the body's opioid and other signaling systems and by reducing inflammatory chemicals in the tissue and spinal cord.^{[6, 7]} Much of this work comes from animal studies, so these are proposed explanations and not settled facts about injured athletes.

What treatment involves

Treatment uses fine, sterile, single-use needles placed near the injured area and at points elsewhere on the body, usually left in place for about 20 to 40 minutes. A course is several visits, and we reassess progress along the way. Trials in ankle sprain and muscle soreness varied widely in how many sessions they used.^{[8, 10]}

Serious problems are rare. In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, pain or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[13] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Sports Injury

The Ayurvedic view

Ayurveda has no single condition that matches "sports injury". Injuries are traditionally understood by their features: sudden pain and stiffness are linked to aggravated Vata, and heat and swelling to Pitta. In this framework, healing depends on the person's constitution, digestion and daily routine. These are traditional categories, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally includes:

• Diet and daily routine that support rest, regular meals and sleep during recovery
• Warm herbal oil massage (abhyanga) around, but not directly on, a fresh, swollen injury
• Herbs traditionally used for strength and inflammation, such as ashwagandha and turmeric
• Local herbal preparations applied to the skin, including transdermal medication therapy

Panchakarma is not appropriate during pregnancy, acute illness or frailty, and heat or oil is not suitable on a new injury with marked swelling until a clinician has assessed it.

What the research shows

No clinical trials of Ayurvedic treatment for injured athletes were found, so the evidence for the injury itself is none. Related research is limited to healthy people. In a placebo-controlled trial of 57 healthy men doing resistance training, those given ashwagandha root extract for eight weeks had larger gains in muscle strength than those given placebo, and the authors also reported less exercise-induced muscle damage based on creatine kinase.^[14] A trial of 50 healthy athletic adults reported better endurance and recovery questionnaire scores with ashwagandha than placebo.^[15] Both were small trials in healthy people, not in people with an injury, and they do not show that ashwagandha speeds recovery from an injury.

Herbal medicine for Sports Injury

Herbs and formulas that have been studied

Studied herbs and formulas include Dangguixu-san, a Korean herbal formula used for pain and swelling after ankle sprain, and curcumin, the main compound in turmeric, for exercise-induced muscle soreness.^{[9, 16]}

What the research shows

The evidence is limited. In a double-blind trial of 48 people with a recent grade I or II ankle sprain, all given acupuncture, those who also took Dangguixu-san had a greater reduction in pain between the end of treatment and week 5 than those given placebo. The trial was small and done at two Korean hospitals, so the finding needs confirmation.^[16]

A meta-analysis of randomized trials found that curcumin supplements lowered creatine kinase and muscle soreness after exercise, but the authors noted that results across studies were inconsistent.^[9] This research is in people with exercise-induced soreness and not in torn or sprained tissue.

A Cochrane overview rated the evidence for herbal remedies applied to the skin for pain as very low quality. Moderate- to high-quality evidence supports some topical anti-inflammatory gels, such as diclofenac and ketoprofen, for acute sprains and strains, and these are medical products to discuss with your physician or pharmacist.^[17]

Safety and herb-drug interactions

Herbs can interact with medicines. Case reports describe bleeding when warfarin was combined with herbs including dan shen, dang gui, ginger, ginseng and Boswellia.^[18] Tell us about every medicine and supplement you take, including anti-inflammatory painkillers.

Product quality also matters. About one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[19] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, have liver or kidney disease, or have surgery planned. Sports and muscle-building supplements deserve particular caution, since liver injury from herbal and dietary supplements is a recognized problem.^[20]

Translating traditional medicine into modern biological language

This is interpretation, not equivalence. Chinese medicine describes many sports injuries as stagnation of qi and blood in the channels around the injured area, with swelling and bruising seen as blood stasis. Researchers studying acupuncture look at things that loosely parallel this: local inflammatory signaling, nerve pathways that carry pain, and the body's own opioids.^{[6, 7]}

In Ayurveda, aggravated Vata and Pitta describe pain, stiffness and heat after injury. No study has shown that a dosha or a pattern of qi corresponds to a specific biological process in injured tissue.

How this care fits with your medical care

Integrative care for sports injury is complementary. Keep your physician, physical therapist or sports medicine specialist, and do not stop or change prescribed medicines or rehabilitation without their advice. We do not diagnose the injury, so a significant injury should be examined first, particularly if you cannot bear weight or the joint looks deformed.

Please bring your diagnosis, imaging reports, your rehabilitation plan, a full list of medicines and supplements, and details of any recent steroid injections or surgery.

When to seek urgent medical care

Some injuries need prompt assessment for a fracture, dislocation, serious ligament or tendon tear, or head injury.^[1]

• A visibly deformed limb or joint, or a bone that may be broken
• Inability to bear weight or use the limb after an injury
• Numbness, a cold or pale limb, or pain out of proportion to the injury
• A head injury with confusion, vomiting, worsening headache, blackout or drowsiness
• Severe or fast-growing swelling, or fever with a red, hot joint
• Chest pain or trouble breathing during or after exercise

If any of these occur, call 911 or go to the nearest emergency department.
