Health & Exercise Forum

Several years ago, while hiking to the bottom of the Grand Canyon with my family, my wife Esther developed “canyon knee,” also known as “hiker’s knee” or in medical terms, “patellar tendonitis.” Regardless of the term, the end result was that she had severe pain in the tendon below her knee cap and was unable to walk up the trail to get out of the canyon. In addition to ice, rest, bracing, and non-steroidal anti inflammatory medications, the National Park Ranger insisted that she use two trekking poles on her ascent to the rim.

Prior to that experience, I always thought that “walking, hiking sticks or trekking poles” were for show or those in need of a walking aide. Well, I could not have been more incorrect. Needless to say, Esther made it out of the canyon safely and, with the use of our life saving trekking poles; we have lived “happily ever after!” Now, 15 years later, I rarely walk more than 5 miles without my poles.

As a result of this experience, I have been recommending walking or trekking poles to my patients. These poles are an essential part of hiking or distance walking gear, for the novice and expert alike. Specifically, for those over 50 who have degenerative arthritis and pain in their lower back, hips, knees, ankles or feet, these simple devices have been shown to improve the efficiency of the exercise and lessen the impact on the spine and lower extremities. Additionally, using poles reduces the likelihood of ankle sprains and falls during walking. Trekking poles are also a safe option for those with compromised balance. If you want to walk distances for exercise and need a little stability but don’t want the stigma of a cane, trekking poles are for you.

History of the Hiking Stick:

Early explorers, Europeans and Native Americans have been using walking sticks for centuries. More recently, in the 1968 classic hiker’s bible, “The Complete Walker,” Colin Fletcher praised his “walking staff” for its multipurpose use: for balance and assistance with walking and climbing, protection from rattlesnakes, and for use as a fishing rod. Today, these sticks are now versatile poles made from light-weight materials.

Trekking Pole Features:

Trekking poles are made of light-weight aluminum and vary in cost and quality. But, like most things, “you get what you pay for!” These hollow tubes can telescope to fit any person and collapse to pack in luggage for travel. Better poles offer multiple removable tips for various uses, conditions and terrains. For example, abasket to prevent sinking too deeply in snow, mud or sand; a blunt rubber tip for hard surfaces like asphalt or concrete, or the pointed metal tip to grip ice or hard dirt/gravel. Better quality poles offer an ergonomic hand grip and strap and a spring system to absorb shock through your hands, wrists and arms upon impact.

The poles should be properly adjusted to fit each individual. When your hand is griping the handle the elbow should be at a 90 degree angle. Proper use is simple; just walk with a normal gait pattern of opposite arm and leg swing. For example, left leg and right arm/pole swings forward to plant while the left arm/pole remain behind with the right leg .  

This pattern is reciprocated with as normal gait advances (opposite arm and leg). I have been very pleased with my moderately priced poles (Cascade Mountain Tech from Dick’s Sporting Goods ($34.99 per pole). Prices range from $19.99 to 79.95 per pole. dickssportinggoods.com; montem.com; leki.com; rei.com. However, if you travel frequently to hike the State and National Parks, you may want to purchase more expensive poles that collapse and retighten more efficiently. (montem.com; leki.com;)

Research:

There are numerous studies to support the use of trekking poles, especially research that supports their use for health and safety. One study compared hikers in 3 different conditions; no backpack, a pack with 15% body weight and a pack with 30% body weight. Biomechanical analysis was performed blindly on the three groups and a significant reduction in forces on lower extremity joints (hip, knee, and ankle) was noted for all three groups when using poles compared to those not using poles.

Another study confirmed that trekking poles reduced the incidence of ankle fractures through improved balance and stability. Additional studies support the theory that trekking poles reduce exercise induced muscle soreness from hiking or walking steep terrain and another study found that while less energy is expended in the lower body muscles using poles, increase energy is used in the upper body; therefore, the net caloric expenditure is equal as it is simply transferred from the legs to the arms.

Reasons to Use Trekking Poles:

• Reduced Stress on Lower Back, Hips, Knees, Ankles and Feet – Biomechanical studies confirm that using trekking poles creates less stress on the lower back and joints of the lower body. Those with a history of degenerative arthritis and pain in these areas are wise to consider this when planning to hike or walk distances for exercise.
• Improved Stability and Balance/Less Injury – Studies have found that those using trekking poles were less likely to suffer sprains, strains and even fractures of the lower body, especially the ankle, due in great part to the improved balance and stability. This benefit is found not only on uneven terrain, but also for those walking distances and may have age-related balance issues.
• Upper Body Workout – One comment I have heard from those questioning the value of trekking poles is that they do not want to make their walking/hiking exercise too easy because they desire a “good workout.” Studies show that the caloric expenditure is equal to exercise without using poles as the energy is simply transferred from the legs to the arms.
• Improve Walking Posture and Stride - It is common when walking distances, especially if carrying a backpack, to lean your trunk forward. Using poles has been found to promote a more upright posture while walking.
• Less Perception of Cardiovascular Exertion - While cardiovascular demands increased with pole walking, subjects reported less exertion when using poles. 
• Reduced Exercise Induced Muscle Soreness - Studies testing the blood for chemicals associated with muscle damage found less exercise induced muscle soreness/tissue damage and delayed onset muscle soreness among pole users. This was reported to be critical in walkers and hikers who participated in their activities several days in a row to complete the task such as hiking in and out of a canyon.

In conclusion, it is important to remember that trekking poles for hiking or distance walking are much more than a style statement. They are proven to be an invaluable tool for health, safety and wellness by reducing lower extremity joint stress, improving stability and balance, and enhancing efficiency for muscle recovery.
