A condition that occurs when a tendon repeatedly overused and not allowed to fully heal, leading to degeneration of the tendon tissue.

The inflammation of a tendon and its surrounding synovial sheath, which lubricates the tendon and allows it to move smoothly.

These are fluid-filled sacs that cushion and protect tendons from friction as they glide over bones.

The most common type of bursitis is the inflammation of the subacromial bursa, located near the shoulder joint.

An injury to the olecranon bursa, located on the bony bump of the elbow, causes pain and swelling at the elbow.

The first stage of tissue healing, characterized by inflammation, redness, swelling, pain, and increased temperature.

The second stage of tissue healing, where new cells and blood vessels are formed to repair damaged tissue. This stage also focuses on scar tissue formation.

The final stage of tissue healing where the scar tissue strengthens and remodels. This can take weeks or even months, depending on the injury.

The inflammatory response phase is crucial for healing and sets the stage for the other phases. Without it, the other phases cannot occur.

The duration of the inflammatory response phase is approximately 2 to 4 days after the injury.

The fibroblastic repair phase can last for 4 to 6 weeks, during which scar formation and repair of the injured tissue occurs.

Interfering with the healing process, such as returning to activity too soon, can delay the return to full function.

Creating a conducive environment for healing includes managing pain, controlling inflammation, and providing adequate rest.

Exercises used in a rehabilitation program, designed to address specific injury limitations and restore function.

Activities that maximize performance while minimizing injury risk. These exercises are used to improve overall fitness and prepare for competition.

The process of restoring function and minimizing injury risk. It involves professional supervision and a carefully planned program of therapeutic exercises.

These professionals are responsible for designing and overseeing the rehabilitation program for injured athletes.

The goal of rehabilitation is to return to activity as quickly and safely as possible, considering the limitations of the healing process.

Pain perception is influenced by the severity of the injury, athlete's response to pain, their perception of pain, and the circumstances surrounding the injury.

POLICE is a mnemonic acronym for Protection, Optimal Loading, Ice, Compression, Elevation, and it's a set of initial pain management strategies.

Restoring full range of motion after an injury requires addressing muscle and ligament restrictions. This can be achieved through various stretching techniques like dynamic, static, and PNF.

Core stability is essential for proper movement and function. The core region includes the lumbar, pelvic, and hip areas, which dynamically stabilizes the body.

Core stability should be addressed before strengthening exercises, as a stable core is crucial for optimal distal movement.

Restoring muscular strength, endurance, and power are crucial for returning to pre-injury function. Various exercises like isometric, progressive resistance, isokinetic, and plyometric are used.

The primary goal of muscle restoration is achieving full pain-free range of motion (ROM). This ensures optimal recovery and injury prevention.

The mind's ability to consciously control a specific movement, relying on the central nervous system to interpret sensory and movement information and coordinate muscle and joint actions.

Rehabilitation involves restoring function and minimizing future injury risks. It requires professional guidance and a tailored exercise program.

Regaining the ability to follow a previously learned movement pattern. It's like re-teaching your body the correct sequence of steps.

Exercises that mimic real-life movements and activities, helping the athlete regain functional movement. They're essential for rebuilding neuromuscular control.

The ability to maintain balance and stability. It's crucial for returning to sports, as poor balance can increase the risk of re-injury.

Exercises specifically designed to improve balance. They're an important part of rehabilitation, especially for athletes.

The ability of the heart and lungs to deliver oxygen to the muscles during exercise. It's often overlooked during rehabilitation, but needs to be maintained to avoid losing fitness.

A series of gradually progressive activities that prepare an athlete to return to their sport.

Breaking down sport-specific skills into their individual components and practicing them within the athlete's limitations. This allows for a gradual return to full activity.

A process that uses drills to determine an athlete's ability to perform a specific activity.

Methods used in rehabilitation to manage pain, inflammation, and promote healing.

Using cold packs to reduce swelling and pain after an injury.

A test involving multiple maximal efforts to assess an athlete's readiness for full activity.

Applying ice packs for 20 minutes to minimize swelling and pain.

Includes cryotherapy, thermotherapy, ultrasound, electrotherapy, light therapy, massage, traction and intermittent compression.

A modality that uses cold therapy to reduce inflammation and pain.

A form of therapy that uses heat to increase blood flow and reduce pain. It's typically used during the fibroblastic-repair phase.

This modality uses electrical currents to reduce pain, stimulate muscle contractions, and promote wound healing.

This modality uses sound waves to increase blood flow, reduce inflammation, and promote tissue healing.

This modality uses low-level laser light to reduce pain, stimulate tissue regeneration, and improve wound healing.

The process of returning an athlete to their sport following an injury. It involves a gradual progression of activities to restore function, strength, and skills.

Using heat to increase blood flow and lymphatic drainage after an injury. It helps remove waste products and promote healing, but should be used cautiously and after the initial inflammation period.

Inflammation is the body's natural response to injury, and it involves redness, swelling, pain, and increased temperature. It's crucial for initiating healing, but can become chronic if the source of irritation persists.

Therapeutic interventions should be tailored to the individual and the stage of healing. Consider pain, swelling, range of motion, strength, and function to determine the appropriate treatment goals.

Moist heat packs, containing silicate gel in cotton pads, are used to provide a consistent temperature for 20-30 minutes. They require multiple layers of towels to prevent burns and athletes should not lie directly on top of them.

The rehabilitation plan should be tailored to the specific injury and athlete. It involves addressing pain, restoring range of motion, increasing strength, and regaining functional skills.

Rest, Ice, Compression, and Elevation (RICE) are the initial steps in managing acute injuries. They help control inflammation and pain in the early stages.

The team physician ultimately holds the responsibility for determining the athlete's readiness to return to play. Collaboration and communication among the sports medicine team are crucial for appropriate decision-making.
