|November 25, 2010
Summary
Repetitive physical activity, like Kendo, can cause skin issues such as painful hyperkeratosis. This case highlights how mechanical stress from sports may lead to common, yet often overlooked, skin reactions.
Area of Science:
- Dermatology
- Sports Medicine
- Biomechanics
Background:
- Repetitive mechanical stress is a known factor in certain skin conditions.
- Understanding the relationship between physical activity and skin response is crucial for diagnosis and prevention.
Observation:
- A 22-year-old male developed painful hyperkeratosis on his heel after starting Kendo.
- He also presented with scaly, atrophic macules on his other sole.
- These symptoms are attributed to the repetitive stamping and friction involved in Kendo.
Findings:
- The study identifies a direct correlation between repetitive mechanical activity in Kendo and the development of specific cutaneous lesions.
- Hyperkeratosis and atrophic macules were observed as direct results of physical stress on the skin.
Implications:
- This case suggests that mechanically induced skin reactions may be more prevalent than commonly recognized.
- Further research into the interaction between physical activity and cutaneous reactivity is warranted.
- Clinicians should consider occupational and recreational physical stresses when evaluating skin disorders.

01:21Characteristics of Dry Friction
Dry friction occurs when two solid surfaces slide against each other without any lubrication or fluid present. It causes resistance when pushing objects along a surface, like a gardener pushing a wheelbarrow. The force applied to move the cart causes dry friction between the wheel and the ground.
Before the wheelbarrow starts moving, the static frictional force acts tangentially to the contact surface, opposing the force that is about to induce the motion. This frictional force prevents the...

01:30Dry Friction
Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible.

01:26Kinetic Friction
Consider a truck trying to pull a stationary car. As the truck exerts a force on the car, static friction is created at the point of contact between the two surfaces. This frictional force resists the car's movement and keeps it at rest. However, when the applied force by the truck surpasses the limiting static frictional force, an interesting phenomenon occurs. The frictional force at the interface reduces to a lower value, known as the kinetic frictional force. At this point, the car begins...
01:27Types of Friction Problems
Friction is an essential concept in physics, engineering, and everyday life. It is the force that opposes the relative motion or tendency of such motion between two surfaces in contact. One of the most common types of friction encountered in various applications is dry friction. Dry friction problems can be broadly categorized into three types, each with unique characteristics and challenges.
The first type of dry friction problem involves situations where there is no apparent impending motion.

01:24Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
01:07Frictional Force
When a body is in motion, it encounters resistance because the body interacts with its surroundings. This resistance is known as friction, a common yet complex force whose behavior is still not completely understood. Friction opposes relative motion between systems in contact, but also allows us to move. Friction arises in part due to the roughness of surfaces in contact. For one object to move along a surface, it must rise to where the peaks of the surface can skip along the bottom of the...
