• Support Level 4 Classification: Within the Kedley support grading system, Level 4 represents medium-firm support — providing meaningful compression and stabilisation without the rigidity of a splinted or hinged device. This level is clinically appropriate for managing chronic thumb conditions during daily activity, returning to tasks following acute thumb injury, and sport or occupational use where the thumb is at risk of further strain.
• CMC Joint Focus: Unlike simple thumb sleeves, the Kedley wrap is designed with an adjustable loop that encircles the thumb at its base — the carpometacarpal (CMC) joint — rather than along the shaft of the thumb. This is the anatomically critical site for basal thumb arthritis, collateral ligament injuries from forced adduction or abduction (common in skiing, ball sports, and falls), and De Quervain's tenosynovitis affecting the abductor pollicis longus and extensor pollicis brevis tendons.
• Pro-Light Neoprene Construction: The Pro-Light grade uses a thinner, more flexible neoprene compared to standard neoprene braces, reducing bulk on the hand while maintaining full thermal and compressive properties. The Nylon and Polyester infusion adds structural strength and shape retention through repeated use and washing cycles, maintaining consistent compression over the product's lifespan.
• Intended Uses: Thumb sprains and collateral ligament injuries, De Quervain's tenosynovitis, first CMC joint osteoarthritis (basal thumb arthritis), rheumatoid arthritis affecting the thumb, general thumb instability, overuse and repetitive strain injuries of the thumb, and return-to-activity support following thumb injury.
• MHRA Registration: The Kedley range is registered with the Medicines and Healthcare products Regulatory Agency (MHRA) UK, providing assurance of product safety standards for medical support devices.

• Thumb Sprains & Collateral Ligament Injuries: The most common mechanism is forced deviation of the thumb — a fall onto an outstretched hand, a skiing pole impact (Skier's Thumb), or a ball sport impact causing ulnar collateral ligament (UCL) sprain. The Kedley wrap provides compression and limiting of the extremes of thumb abduction during the subacute and recovery phases.
• Basal Thumb Arthritis (First CMC Osteoarthritis): Among the most prevalent arthritic conditions in adults over 50, particularly in women. The combination of neoprene warmth and gentle compression at the CMC joint addresses two key components of arthritic thumb management — heat therapy and joint stabilisation — both recommended within conservative management guidelines.
• De Quervain's Tenosynovitis: Inflammation of the tendons on the thumb side of the wrist (APL and EPB). Compression and warmth at the base of the thumb can help reduce tendon irritation during activity, particularly where splinting is not required or has been graduated down.
• Repetitive Strain & Occupational Use: Workers in roles involving sustained pinch grip, keyboard use, assembly work, or other repetitive thumb activity benefit from the proprioceptive feedback and compression the wrap provides, reducing cumulative strain on the CMC joint and surrounding tendons.

• CMC Joint Compression & Stabilisation: The adjustable thumb loop applies direct compression to the periarticular soft tissues of the first CMC joint. This external support reduces the translational and rotational forces that stress the joint during pinch and grip activities — the loading patterns that most commonly provoke pain in basal thumb arthritis and collateral ligament injuries. By limiting the extremes of joint excursion, the wrap allows functional hand use while protecting the vulnerable joint structures.
• Thenar Musculature Support: The wraparound component extends compression across the thenar eminence — the muscular pad at the base of the thumb — providing support to the abductor pollicis brevis, opponens pollicis, and flexor pollicis brevis muscles. This is particularly relevant in De Quervain's tenosynovitis and repetitive strain presentations, where the thenar muscles are involved in the inflammatory cycle.
• Thermal Therapy: The neoprene layer raises the local temperature around the CMC joint and surrounding soft tissue during wear. This promotes vasodilation and increased blood flow, reduces stiffness in the joint capsule and periarticular connective tissue, and is associated with decreased pain perception in arthritic and tendinopathic conditions. The continuous thermal effect throughout the wear period is more clinically beneficial than intermittent heat therapy for chronic conditions.
• Proprioceptive Enhancement: Hand and wrist injuries reduce the proprioceptive acuity of the affected joints. The constant tactile input from the wrap improves sensory feedback about thumb position and movement, helping the nervous system protect the joint from harmful end-range loading during functional tasks — an important component of injury prevention during the return-to-activity phase.

Fitting — LEFT Hand:

• Lay the wrap flat with the K-tag upside down, positioned to the left.
• Rotate the light grey tab to the back, then over the front, forming a loop. Press down to fasten the loop securely.
• Put the left thumb through the loop, with the wrap positioned over the back of the hand.
• Wind the loose end around the hand and fasten the Velcro comfortably onto the back of the wrist. Adjust as required.

Fitting — RIGHT Hand:

• Lay the wrap flat with the K-tag upright, positioned to the right.
• Rotate the light grey tab to the back, then over the front, forming a loop. Press down to fasten.
• Put the right thumb through the loop, with the wrap positioned over the back of the hand.
• Wind the loose end around the hand and fasten the Velcro comfortably onto the back of the wrist. Adjust as required.

• Checking the Fit: After application, the wrap should feel firmly supportive at the base of the thumb without restricting circulation. Ensure the thumb and all fingers remain warm, with normal sensation and capillary refill. If any finger becomes cold, numb, or discoloured, loosen immediately.
• Duration of Wear: Wear during activity and tasks that load the thumb. Remove during rest periods. Avoid continuous overnight wear unless directed by a healthcare professional. Inspect the skin beneath the wrap regularly for pressure marks or irritation.
• Washing & Storage: Hand wash in lukewarm soapy water. Rinse and air dry. Do not machine wash, tumble dry, or iron. Store in a cool, dry place away from direct heat and sunlight.
