Proper Lifting

Why is the proper lifting technique important?

One of the most common causes of lower back injury is incorrect lifting technique. When you lift an object with bad posture, this causes a greater load to be placed through the bones, ligaments and discs in your spine which may lead to injury. Remember to use the correct body mechanics to lift safely and prevent back injury.

Before you lift, make sure to consider the following:

Lifting steps:

  1. Stand close to the object you will be lifting.
  2. Keep a wide stance – your feet should be shoulder width apart with one foot being slightly in front of the other to keep balance.
  3. Squat down when picking up the object by bending your knees and keeping your back straight. Bending your knees reduces the load that is created in your lower back, which can prevent back injuries from occurring.
  4. Lift the object slowly by using your arm and leg muscles rather than your back muscles and straightening your hips and knees. Breathe out as you lift. Remember to keep your back straight and do not twist while lifting!
  5. Hold the object as close to your body as possible. Hold the object near your abdomen region – do not hold the object above shoulder level.
  6. Pivot your feed by taking small steps to change directions. Do not twist your body.
  7. Bend your knees while slowly and carefully lowering the object to the new location.
  8. Spinal Stenosis

    What is spinal stenosis?

    Spinal stenosis, or narrowing of the spinal canal, is a condition that can squeeze sensitive spinal nerves. Some people with spinal stenosis may not have symptoms. Others may experience pain, tingling, numbness and muscle weakness. Symptoms can worsen over time.

    The most common cause of spinal stenosis is osteoarthritis, the gradual wear and tear that happens to your joints as you age over time. Spinal stenosis is common in older adults because osteoarthritis begins to cause changes in most people’s spines by age 50.

    The two main types of spinal stenosis are:

    1. Cervical stenosis: In this condition, the narrowing occurs in the part of the spine in your neck.
    2. Lumbar stenosis: In this condition, the narrowing occurs in the part of the spine in your lower back. This is the most common form of spinal stenosis.

    Symptoms

    Cervical spine (in the neck):

    • Numbness or tingling in a hand, arm, foot or leg
    • Weakness in a hand, arm, foot or leg
    • Problems with walking and balance
    • Neck pain
    • In severe cases, bowel or bladder dysfunction (urinary urgency and incontinence)

    Lumbar spine (in the lower back):

    • Numbness or tingling in a foot or leg
    • Weakness in a foot or leg
    • Pain or cramping in one or both legs when you stand for long periods of time or when you walk, which usually eases when you bend forward or sit
    • Back pain

    How can chiropractic treatment help with spinal stenosis?

    Chiropractic treatment is an all-natural, non-invasive method of helping relieve painful symptoms as well as addressing spinal stenosis directly at the source. Chiropractic approaches spinal stenosis holistically; taking into account your symptoms, the current state of your spine, how your body is feeling, what makes your symptoms better or worse, and what you feel comfortable doing.

    To diagnose spinal stenosis, your chiropractor may ask you about signs and symptoms, discuss your medical history, and conduct a physical examination. Then, they may order several imaging tests to help pinpoint the cause of your signs and symptoms. Imaging tests include, X-rays, magnetic resonance imaging (MRI), or CT scan. Spinal manipulation and other manual adjustments are the primary method of treatment.

    Chiropractic treatment aims to widen the space available for the spinal cord within the spinal canal. By correcting the displacement of spinal discs, relieving tension held in tight muscles, and removing the pressure from spinal nerves, a patient with spinal stenosis can experience lessened symptoms. Chiropractic care is drastically less invasive than other treatment options such as injections, harmful medications, or open spine surgery.

    Tenosynovitis

    Tenosynovitis is the inflammation of the fluid-filled sheath (called the synovium) that surrounds a tendon, typically leading to joint pain, swelling, and stiffness. The sheath of the tendon becomes thinner which is caused by the reduced lubrication between tendon and its sheaths due to the excess rubbing movements. Some secondary factors that increase the risk of tenosynovitis is having improper skill and posture when moving the wrist. The 2 common types of tenosynovitis are De Quervain’s Tenosynovitis and Trigger Finger Tenosynovitis.

     

    De Quervain’s Tenosynovitis:

    De Quervain’s Tenosynovitis is a condition that affects the tendons in your wrist. Repeating a particular motion may irritate the sheath around the two tendons, causing thickening and swelling that restricts their movement. This condition affects tendons that abduct and extend the thumb necessary for dexterity and manipulation.

    The exact cause of this type of tenosynovitis is unknown. However, any activity that requires repetitive hand or wrist movement can aggravate the condition – such as knitting, racket sports, lifting a baby, and walking a pet. Treatments for De Quervain’s Tenosynovitis include wearing a thumb splint to immobilize the thumb, preventing further abduction of the thumb.

     

    Trigger Finger Tenosynovitis:

    Trigger finger tenosynovitis is tenosynovitis of tendons that flex fingers. The cause of this condition occurs from repetitive and forceful flexing of fingers. As a result, one of the fingers gets stuck in the bent position due to the bulbous swelling that restricts finger flexion and may lock them in a fixed position. A bump, also known as a nodule, may occur from the inflammation of the tendon sheath. Trigger finger occurs mostly near metacarpophalangeal joints, middle and ring fingers of the dominant hand.

    People whose work or hobbies require repetitive gripping actions are at higher risk of developing trigger finger tenosynovitis. Additionally, those with health problems such as rheumatoid arthritis and diabetes are at higher risk.

    Ligaments and Tendons

    Posted on May 13, 2020 by

    Tendons and ligaments are fibrous bands of connective tissue that help stabilize body structures and facilitate body movements. The main difference between tendons and ligaments is that they connect different parts of the anatomy. Tendons connect muscles to bones, while ligaments connect bones to other bones.

    Ligaments and tendons are made of 2 types of protein fibers: collagen and elastin. Collagen fibers have a small deformation range and high strength. Since collagen has such a high strength, they require more force to break down. Contrarily, elastin fibers have a large deformation range with low strength, meaning they are very weak and can break more easily. Ligaments such as the neck and wrists have more motion and movement because they consist of more elastin and less collagen.

    Ligaments and Tendon Injury:

    Repetitive motions with inadequate recovery periods are the cause of occupational ligament and tendon injuries due to the constant loading and unloading of force with no rest. Loading is the process of physical stresses acting on the body or on anatomical structures within the body.

    A ligament injury occurs during the chronic process of loading and unloading, the tissue becomes longer and more fragile and eventually a small amount of force can easily fracture. In addition, cumulative loading can result in a decrease in bone density which increases the vulnerability of a ligament or tendon getting injured. An example of constant loading is by having improper posture for long periods of time which eventually leads to lower back injury.

    Stages of Ligament Healing:

    1. Acute inflammatory phase – The first stage consists of the formation of blood clot within the damaged region.
    2. Proliferative phase – New blood vessels are formed while fibroblasts are recruited from circulation to produce new collagen.
    3. Tissue remodeling phase – The third stage starts after 3 weeks of the injury occurrence. During the wound healing process, there is a progressive maturation of collagen fibers in response to loads experienced by the ligaments. If force is applied in the wrong direction, there can be permanent damage of the ligaments.

    Resistance Training

    Posted on May 7, 2020 by

    Resistance training, also known as strength training, is a form of exercise that improves muscular strength and endurance. During a resistance training workout, you move your limbs against resistance provided by your body weight, gravity, bands, weighted bars or dumbbells. Resistance training is recommended to be exercised 2 times in a week. Exercises should be individualized depending on the individual’s knowledge on how to do specific exercises. Kinesiologists specialize in designing exercise programs for patients that need help overcoming chronic injuries and pain.

    The Benefits Of Resistance (Strength) Training:

    Types of Resistance Training:

    1. Calisthenics – Consists of a variety of movements that exercise large muscle groups, including push ups, sit ups, and running
    2. Weights – Strength training tools such as free weights, machines, kettle-bells, cables/pulleys

    Benefits of Resistance Training:

    Resistance training can increase tensile strength of connective tissues – helping to strengthen tendons, muscle, and ligaments. It allows tissue to generate more tension and which makes them more resistant to injury. Strength exercises can contribute to optimal performance in daily activities, as it improves posture, encourages weight loss and maintenance, and lowers injury risk. Strength training also reduces the need to do more cardiovascular activities because it helps control blood sugar.

    This type of training can also be extremely beneficial for older adults because it improves mobility and functional independence. Implementing resistance training in your physical activity can help in the long run by delaying bone diseases such as osteoporosis – a condition where bones lose their mineral content/bone density and become more vulnerable to fracture. Bone density is improved when stress is put on bones by doing resistance exercises. 

    Guidelines for Resistance Training:

    1. Do exercises that involve all major muscle groups (chest, shoulders, back, hips, abdomen, arms)
    2. To improve good posture, select exercises that strengthen the trunk (abdomen)
    3. Never lift heavy weights alone (have a spotter)
    4. Warm up prior to high intensity exercises
    5. Use proper lifting techniques to prevent musculoskeletal injuries
    6. Exercise larger muscle groups before smaller ones (Ex. exercise legs before arms)
