Musculoskeletal Injury Prevention and Management in Esports
This domain tests your ability to reason about overuse complaints driven by sustained static posture and high-frequency, low-force repetition. Expect items on common sites, load-related mechanisms, prevention programming, red flags, and referral triggers.
Common presentations
- Wrist and hand: De Quervain tenosynovitis, thumb carpometacarpal irritation, carpal tunnel syndrome, extensor and flexor tendinopathy.
- Elbow: lateral epicondylalgia from repetitive wrist extension and grip.
- Shoulder and neck: myofascial neck pain, scapular dyskinesis, thoracic stiffness from prolonged flexion.
- Lumbar: sustained sitting with poor support and low movement variety.
Prevention principles
- Manage exposure, not just posture. Total mouse and keyboard hours, intensity, and sudden spikes matter more than a single ideal position.
- Microbreaks. Short, frequent interruptions with wrist, shoulder, and neck movement beat one long break.
- Strength and endurance. Wrist extensors and flexors, grip endurance, scapular retractors, deep neck flexors, and thoracic mobility.
- Equipment fit. Mouse size and grip style, keyboard angle, arm support, chair and desk height.
- Sleep and stress. Pain sensitivity rises with sleep debt and competitive stress; a purely biomechanical plan fails.
Red flags requiring referral
Progressive numbness in a median nerve distribution, night pain waking the athlete, visible muscle wasting, sudden loss of dexterity, or pain that worsens steadily despite two weeks of load modification.
Worked example
A player doubles scrim hours from four to eight daily over one week and reports radial-sided wrist pain that is worse on mouse grip. Reasoning: this is a load spike, and the differential includes De Quervain tenosynovitis and wrist extensor tendinopathy. Do not diagnose. Reduce provocative exposure by roughly 20-30 percent, add grip and wrist extensor loading at tolerable intensity, adjust mouse grip and arm support, and screen for red flags. If pain is unchanged at two weeks, or any red flag is present, refer to a hand therapist or physiotherapist.
Traps that cost marks
- Prescribing complete rest, which deconditions the forearm and rarely matches the athlete's reality.
- Treating pain as purely structural while ignoring sleep, stress, and total screen time.
- Naming a diagnosis outside your scope.
- Ignoring equipment after the pain resolves, which invites recurrence.
