Foot injuries Topics Lyme disease Effects of density altitude 3
Foot Injuries Each of your feet has 26 bones, 33 joints, and more than 100 tendons, muscles, and ligaments. A lot of things can go wrong - few common problems: Bunions: hard, painful bumps on the big toe joint Calluses/corns: thickened skin from friction or pressure Plantar warts: warts on the soles of your feet Fallen arches: flat feet Blisters Ill-fitting shoes often cause these problems. Aging and being overweight also increase your chances of having foot problems 4
Foot Injuries What is a Foot or Ankle Sprain or Fracture? A foot or ankle sprain is a soft tissue injury. A sprain occurs when an injury pulls, stretches, or tears the ligaments that connect bone to bone. A fracture is actually a break in the bone. Causes Injuries are the most common causes of foot and ankle sprains and fractures. Many fractures and sprains occur during sports. Football and soccer players are particularly vulnerable to foot and ankle sprains and fractures. Basketball players are prone to ankle sprains, and runners may develop stress fractures of the ankle or foot. Gymnasts and dancers may also develop stress fractures. Tripping or stumbling on uneven ground is another common cause of foot and ankle sprains and fractures. 5
Foot Injury Symptoms and Care Symptoms Pain, swelling, bruising, and difficulty walking on the affected foot or ankle are the most common symptoms of a sprained or fractured foot or ankle Home Care Foot or ankle, err on the side of caution. The acronym R-I-C-E can help you remember what to do: Rest: Rest the affected area. Stay off the injured foot or ankle until it can be fully evaluated. Walking, running, or playing sports on an injured foot or ankle may make the injury worse Ice: Apply ice to the affected area as soon as possible, and reapply it for 15 20 minutes every three or four hours for the first 48 hours after injury. Ice can decrease inflammation Compression: Wrap an elastic bandage (such as an Ace wrap) around the affected foot or ankle. The wrapping should be snug, but not so tight as to cut off circulation Elevation: Elevate the affected extremity on a couple of pillows; ideally, your foot or ankle should be higher than your heart. Keeping your foot or ankle elevated also decreases swelling 6
Foot Injuries Toe, Foot, or Ankle injuries most commonly occur during: Sports or recreational activities (CAP PT activities or encampment) Work related tasks Work or projects around the home Prevention Wear comfortable, supportive shoes Wrap your ankle during activities where injury is a risk Wear properly fitting shoes and socks to eliminate blisters Remove clutter and obstacles from your work area and walking path Do not walk barefoot Stretch and warm up before and after any activity 7
Lyme Disease Transmitted through the bite of infected blacklegged (Deer) ticks Caused by the bacterium Borrelia burgdorferi Symptoms include fever, headache, fatigue, and a characteristic skin rash If left untreated, infection can spread to joints, the heart, and the nervous system. Diagnosed based on symptoms, physical findings (e.g., bulls-eye rash), and the possibility of exposure to infected ticks Most cases can be successfully treated with a few weeks of antibiotics Steps to prevent Lyme disease include using insect repellent, removing ticks promptly, applying pesticides, and reducing tick habitat. 8
Lyme Disease Early localized stage (3-30 days post tick-bite) Red, expanding rash. Fatigue, chills, fever, headache, swollen lymph nodes Erythema migrans (EM) or bull s-eye rash Rash occurs in 70-80% of people. Begins after 3-30 days (avg is 7 days) Rash gradually expands over several days, can reach 12 across. Rash usually feels warm to the touch but is rarely itchy or painful Untreated, infection may spread to other parts of body Facial or Bell s palsy (loss of muscle tone on one or both sides of face) Severe headaches, neck stiffness due to meningitis Pain and swelling in large joints; shooting pains interfering with sleep 9
Preventing Tick Bites Avoid direct contact with ticks (woods and bushy areas with high grass); walk in center of trails Repel ticks with 20% or more of DEET or Permethrin Find and remove ticks from your body Bathe or shower as soon as possible (preferably within 2 hours) Conduct a full-body check (e.g., under arms, behind knees, hair) Examine gear and pets (no free rides!) Tumble clothes in dryer on high heat for an hour to kill remaining ticks 10
Reported Cases of Lyme Disease - 2011 True / False Lyme disease occurs throughout US? Lyme disease is transmitted from person to person? Best way to remove a tick is to grasp tick close to skin with tweezers and pull straight away from skin Tick must be attached to skin for >24 hrs before it can transmit Lyme disease 11
Terms Effects of Density Altitude Indicated Altitude: altitude shown on altimeter True Altitude: height above mean sea level (MSL) Absolute Altitude: height above ground level (AGL) Pressure Altitude: indicated altitude when altimeter is set to 29.92 Hg; used in acft performance calculations and in high-altitude flight Density Altitude: pressure altitude corrected for nonstandard temperature variations 12
Why Does Density Altitude Matter? High density altitude = decreased performance High altitude = less dense air High temperatures = less dense air High humidity related to engine power vice aerodynamic efficiency At 96 o F, water vapor content can be 8X as great as at 42 o F If high humidity, add 10% to computed takeoff distance Increased density altitude Increased takeoff distance Reduce rate of climb Increased TAS (but same IAS) on approach / landing Increased landing roll distance 13
Density Altitude Charts 14
Flight Planning - Density Altitude Runway temperature over a hot, paved surface can be as much as 40 o F greater than temperature reported by sensors Consider running a 2 nd set of T/O data at +40 o F/20 o C More doubtful the weather, the more information you need to obtain If using cell phone, the 1-800-WX-BRIEF number connects you with your cell phone s area code (might not be the one at your location) 15
