Introduction

Tenosynovitis is a condition in which the protective sheath surrounding a tendon becomes inflamed, and it can have a major negative effect on a person's quality of life.¹ Understanding the causes of the condition and taking preventative measures is essential. Ageing, infection, certain medical problems, and repetitive movements are common risk factors.¹ Inflammation and discomfort can result from excessive strain, for example, strain on the tendons in the wrist caused by repetitive activity, including typing, lifting, or playing video games.² Tendons weaken and blood flow supplying essential nutrients to them diminishes with age, increasing the risk of tenosynovitis in middle-aged and older adults. The risk may also be increased by pre-existing medical conditions like diabetes and rheumatoid arthritis. Infections can spread to tendons and cause tenosynovitis, especially those caused by MRSA and Staphylococcus aureus bacteria.³ Reducing tendon strain and preserving general musculoskeletal health are the major goals of tenosynovitis prevention techniques.

Ergonomic adjustments

It is essential to use efficient ergonomic techniques in order to prevent tenosynovitis. Ergonomics optimises the environment, equipment and spaces that people use to promote comfort, safety and efficiency. The use of ergonomic tools and equipment, appropriate hand and wrist alignment, and office workstation alterations are the three main areas of ergonomic adjustments, and are the subject of this article.

The key to avoiding tenosynovitis is to arrange your hands and wrists correctly when carrying out daily tasks. Maintaining a neutral wrist position and avoiding bending your wrists up or down are crucial when typing or using a computer mouse.⁴ When typing, one should have relaxed, straight wrists and fingers that can easily hover over the keys. Inflammation is less likely, and tendon tension is lessened in this neutral position.^4,5

In order to achieve proper hand and wrist alignment, workstation adjustments are essential, particularly for office workers who spend a lot of time at their workstations. Setting the desk and chair at the proper height is crucial.⁶ Your seated position should allow your knees to be at a 90-degree angle, and your feet to be flat on the floor. The desk should be at a 90-degree angle to your torso to permit unrestricted arm movement. Good posture and the avoidance of neck strain are encouraged by placing the monitor so that the top of the screen is at eye level.⁶ Ergonomic Keyboard trays can lessen the strain on your tendons even further by assisting in positioning the keyboard at the proper height and angle.⁶

Stretching and strengthening exercises

Stretching exercises for the fingers and wrists are essential for preserving flexibility and easing tendon stress. Assisted thumb extension (straightening) is a useful exercise in which you raise your thumb toward the ceiling while using the other hand to support the movement.⁷ Repeat ten times while holding the position for five to ten seconds. By using the opposing hand to raise the thumb away from the index finger, assisted thumb abduction is another useful stretch.^7,8 These exercises aid in reducing stiffness and increasing range of motion in the afflicted areas. 

Preventing tenosynovitis requires equally significant hand and forearm muscle strengthening exercises. Both palm-down and palm-up wrist curls are great for working the flexor and extensor muscles of the wrist, respectively.⁸ These workouts entail 15–20 repetitions of curling the wrist toward the body while holding a light dumbbell. Another useful exercise that targets the brachioradialis muscle, a crucial forearm muscle, is the reverse grip curl.⁸ A barbell or cable machine can be used for this exercise, and 10–12 repetitions are advised. 

Push-ups and fingertip holds can be added for more complex strengthening. Fingertip holds, which begin with 5–10 second holds and increase to 30–60 seconds as strength increases, entail bearing body weight on the fingertips in a plank position. The strength and endurance of the forearms are tested by these exercises.

It is impossible to overestimate the significance of intermittently pausing repetitive movements in preventing tenosynovitis. One of the main risk factors for tenosynovitis is prolonged immobility and repetitive motions.⁹ Overall strain can be decreased by putting the 20-20-20 rule into practice, which states that you should stare at something 20 feet away for 20 seconds every 20 minutes.⁹ Simple exercises, like wrist flexion and extension, can be done during these periods. These entail three times a day, five to ten repetitions of bending the wrist forward and backwards to break up long bouts of repetitive movement.

Resistance band workouts can also be a useful preventative measure.¹⁰ For example, strengthening the injured tendons can be achieved by slowly and carefully lowering the thumb to meet the fingers while creating resistance with an elastic band.¹⁰ To target different muscle areas, practice this exercise with the palm facing both up and down a wall. It's crucial to remember that for the best results, these exercises should be done slowly and with controlled motions.¹⁰ Starting with isometric exercises multiple times a day, people should progressively advance to more dynamic motions as their strength and comfort increase.¹⁰ Additionally, enhancing general hand and forearm strength can be achieved by the use of soft, compressible items, such as stress balls, in grip training exercises.

Activity modification and rest 

A comprehensive strategy is needed to prevent tenosynovitis, with rest and activity moderation being key components. The key to lowering the chance of developing this condition is avoiding overuse and repeated actions. Activities involving extended, repetitive hand and wrist movements should be avoided, particularly those that call for uncomfortable postures or excessive force. One useful tactic to reduce strain on specific tendons is to implement work rotation.¹¹ The risk of overuse can be decreased by switching up your routine, such as by alternating document handling with other secretarial tasks. 

Preventing the progression of tenosynovitis requires early symptom recognition and prompt rest.¹¹ It's important to cease an activity if pain or discomfort is felt while performing it, and try the action again lightly the next day. Experts advise taking pauses every 20 to 30 minutes to allow tendons to relax and recover, therefore, regular breaks should be a part of work routines. Simple movements like wrist rotations can be done during these periods to increase flexibility and circulation.

Lifestyle and diet considerations

Key lifestyle and health factors are involved in preventing tenosynovitis. It's critical to maintain a healthy weight because being overweight puts an excessive load on tendons and joints and may exacerbate inflammation. A balanced diet and regular exercise can help you to reach and stay at your ideal weight, which lowers your risk of developing tenosynovitis.²

Preventive measures include drinking enough water and eating a low-inflammatory diet. Eating foods like salmon and sardines that are high in omega-3 fatty acids can help fight inflammation. Furthermore, adding anti-inflammatory foods to one's diet, such as ginger, turmeric, and leafy greens, may offer preventive advantages.² On the other hand, it is advised to limit consumption of foods that cause inflammation, such as processed meals, alcohol, and food high in sodium (salt). In order to prevent tenosynovitis, it is essential to manage underlying medical issues. Certain conditions, like diabetes and rheumatoid arthritis, for example, can make people more vulnerable to tendon inflammation. Tenosynovitis risk can be considerably decreased by routine medical examinations and appropriate treatment of these disorders with medicines and lifestyle modifications.¹²

Sleep is also an important factor in reducing inflammation, as it is a crucial time during which your body repairs and heals itself.

Summary

A multimodal strategy that includes lifestyle changes, exercise, and ergonomic improvements is needed to prevent tenosynovitis. Using ergonomic tools, taking regular pauses during repetitive tasks and maintaining appropriate hand and wrist alignment are important preventative measures. Exercises for wrist, finger, and forearm stretching and strengthening are essential for preserving flexibility and easing tendon tension. In order to effectively manage tenosynovitis, early intervention and consistency are essential. The condition's progression can be stopped by identifying early signs and getting enough sleep on time. Preventative measures can ensure that your quality of life is not affected by this condition. Self-management is vital, but it's also critical to get medical help when needed. It is advised to speak with a healthcare provider if symptoms intensify or continue after taking precautions. They can offer individualised treatment programs that might involve physical therapy, splinting, or, in extreme situations, surgery. People can considerably lower their chance of getting tenosynovitis and preserve optimal performance in both work and leisure environments by implementing these preventative techniques and continuing to be watchful about the health of their hands and wrists.
