Understanding the fundamentals: The wrist and hand encompass a complex network of bones, tendons, ligaments, and muscles crucial for intricate motor functions. These structures facilitate precision and dexterity in everyday activities.

Anatomy of the wrist and hand: The wrist consists of eight small carpal bones arranged in two rows, bridging the forearm and the hand. These bones articulate with the long bones of the forearm, known as the radius and ulna, forming multiple joints that allow for a wide range of motion. The hand comprises five metacarpal bones, extending from the wrist to the base of each finger, and fourteen phalanges, forming the framework for finger movement.

Common orthopedic presentations and their causes:

1. Carpal Tunnel Syndrome: Characterized by median nerve compression within the carpal tunnel, resulting in paresthesia and weakness in the hand. Common causes include repetitive hand and wrist movements, such as typing or assembly line work (Fernández-de-las-Peñas et al., 2020).
2. De Quervain’s Tenosynovitis: An inflammatory condition affecting the abductor pollicis longus and extensor pollicis brevis tendons, leading to pain and restricted thumb movement. Repetitive thumb movements, such as texting or lifting infants, are frequent culprits (Vandenbroucke et al., 2018).
3. Wrist Sprains: Ligamentous injuries often occurring due to forceful dorsiflexion or volar flexion, eliciting pain and edema. Falls onto an outstretched hand or sudden twisting motions during sports activities are common mechanisms of injury (Hume & Munsie, 2013).
4. Ganglion Cysts: Fluid-filled swellings that develop near joints or tendons, causing discomfort and limited range of motion. The exact cause is unknown, but trauma or repetitive stress may contribute to their formation (Gelberman et al., 2017).

Impact of Computer Use: Prolonged computer use can predispose individuals to wrist pathologies such as repetitive strain injuries and carpal tunnel syndrome. Ergonomic modifications and regular breaks are pivotal in mitigating these risks, as outlined in recent research (Smith et al., 2019).

Impact of Cellphone Use: Similarly, frequent and prolonged use of cellphones can contribute to the development of wrist and hand disorders, including text thumb and cubital tunnel syndrome. Increased reliance on handheld devices may exacerbate wrist flexor and extensor muscle imbalances, leading to musculoskeletal dysfunction (Johnson et al., 2021).

Improving fine motor control

Enhancing fine motor control of the wrist and hand is crucial for executing precise movements in daily tasks. Activities such as:

• Drawing or tracing intricate patterns to promote hand-eye coordination and precision.
• Manipulating small objects like beads or coins to enhance finger dexterity and grip strength.
• Playing musical instruments such as piano or guitar to refine finger movements and coordination.
• Engaging in activities like knitting or sewing to improve finger control and tactile sensitivity (Gabbard et al., 2016).

Improving grip strength

Optimal grip strength is essential for various functional tasks and activities of daily living. Activities known to enhance grip strength include:

• Squeezing stress balls or hand grippers to strengthen hand and forearm muscles.
• Using hand-held dynamometers to measure and track grip strength progress.
• Performing farmer’s walks or carrying heavy objects to challenge grip endurance and strength.
• Incorporating resistance band exercises like wrist curls and reverse wrist curls to target specific muscle groups involved in grip strength (Wang et al., 2020).

Rehabilitation strategies: Optimal rehabilitation entails a multifaceted approach encompassing therapeutic interventions aimed at restoring range of motion, enhancing muscular strength, and improving proprioception. Modalities include scapular stabilization exercises, targeted muscle re-education, and functional training protocols tailored to individualized needs.
