Romanian Deadlift Vs. Standard Deadlift: Comprehensive Guide

By Kyran Doyle In Training

Deadlifts are one of the best strength and mass building exercises that you can perform. When performing the deadlift you are working more muscles than any other exercise, including the squat.
Deadlifts have many different variations and forms. In this article we are going to focus on the difference between the Romanian Deadlift and standard deadlifts.
There are lots of valid arguments as to which exercise is better in a Romanian Deadlift vs regular deadlift battle.
Keep reading to learn the differences. Romanian Deadlift Vs. Standard DeadliftThe Romanian Deadlift is one of the most commonly used among the various deadlift techniques. In fact a lot of people that think they are performing a deadlift are sometimes actually doing a Romanian Deadlift.
Both the conventional and Romanian Deadlifts are great strength and muscle building exercises. Even though they are both deadlifts variations the setup, execution and muscles activated are different.

Disc and Ligament Injuries: Documenting the Cause

Disc and Ligament Injuries: Documenting the Cause - El Paso Chiropractor


“The clinical diagnosis shows a disc bulge in their neck and some arthritis, so their neck symptoms are not associated with the crash. Lots of folks have those and do not have pain although it could be a minimal herniation. It’s our diagnosis that it was there before the crash.” This statement from an adjuster is an argument that has been made for many years, allowing insurance companies to inappropriately reduce settlements to their clients based on the client’s inability to prove when or how the damage or injury occurred. To factually counter this sort of statement, an individual must use imaging and age dating to discuss causality. Without medical experts utilizing the current medical and academic research available, it will continue to be difficult for any argument to be made explaining effects of these injuries and their mechanism based on fact vs. rhetoric.

Imaging of the spine is critically important in most cases of injured clients. In cases, imaging is necessary for proper diagnosis and future management of injuries. Imaging needs to be performed as per the academic and modern criteria to ensure an accurate diagnosis. The most common injuries in car accidents are spinal related, and the simple imaging available includes x-rays, CAT scans and magnetic resonance imaging (MRI), allowing medical providers to make an accurate diagnosis, when medically indicated.

Every medical provider has a permit to see and treat automobile related injuries. However a “license” is not the same as “specialization.” By way of example, though psychiatrists may have a license to do heart surgery and are MDs, it would not be in the patient’s best interest. Nor would I go to a spine surgeon for psychological concerns although they are licensed to treat medical conditions. In spinal trauma, certain suppliers specialize in connective tissue injuries of the spine, allowing us to go one step farther in diagnosis, prognosis and management, including “age-dating” these generally found disc and ligament injuries.

Understanding Age-Dating of Injuries


To understand age-dating, one wants to have a basic medical understanding of anatomy and physiology, and what tissue is commonly injured and the probable “pain generator”. Since neck injuries are the most common injuries cervical joints will be our focus. Related to anatomy, every set of two vertebrae in the neck is connected with three joints; two facet joints and a single disc. These joints allow for normal movement of the spine (mobility). There are multiple ligaments that are responsible for stability and hold together these joints. The correct balance of mobility and stability is critical when looking at the part of patient’s injuries, meaning that too little or too much movement in spinal joints can lead to pain, secondary to damaged tissue. The tissue most commonly hurt in a car crash is nerve, ligament, disc, facet and muscle/tendon. Spinal cord and bone injuries also happen although less frequently. To determine causality, the supplier should comment on what tissue is injured, and also use imaging to help determine if this injury occurred (age-dating).

There are two fundamental problems that must be addressed. Fardon and Milette (2001) reported, “The phrase ‘herniated disc’ does not infer knowledge of cause, relation to trauma or activity, concordance with symptoms, or need for treatment” (p. E108). Simply having a disc herniation’s presence, without a physical exam or without symptom documentation that is appropriate, does not allow one to comment on the cause of the injury. In a rear impact collision by way of example, even if the diagnosis is confirmed, additional criteria will need to be fulfilled to answer the question of “Was there sufficient force generated into the vehicle and the occupant to induce the cervical/lumbar herniation?” Fardon, in a follow-up study (2014) reported that disc injury “in the absence of significant imaging evidence of associated violent injury, should be classified as degeneration rather than trauma.” (p. 2531). Thus, we must more objectively define the subjective connotations of “violent injury” and address the issue of “degeneration as opposed to trauma”. Although this statement can frequently be misleading, it gives the trauma trained expert doctor a basis in going forward understanding that every patient’s physiology is unique and not subject to rhetoric, but clinical findings.

Violent injury to the occupant can occur when there are sudden acceleration and deceleration forces (g’s) generated to the neck and head which overwhelm connective tissue or pull them past their physiological limit. To determine the acceleration force, ΔV (delta V) is utilized. ΔV is the change in speed of the occupant vehicle when it is hit from behind (i.e., going from a stopped position to seven mph in 0.5 seconds because of forces moved from the “bullet” vehicle to the “target” vehicle). Utilizing these data, research allows us to make specific comments related to violent injury. Since the cervical spine is subjected to shearing forces, and compression, tension we are oversimplifying. Along with g-forces and the elastic nature of the majority of rear impact crashes makes it almost impossible to discover an actual minimum threshold for injury even though the literature has given us many examples of low-speed crashes which are dependent not simply on speed, but the mass (weight) of the subject vehicles. Each individual’s susceptibility to injury is unique. While g-forces alone are insufficient to predict injury, Krafft et al. (2002) reported that in low-speed collisions there’s an injury threshold of 4.2 g’s for males and 3.6 g’s for females. Krafft’s analysis is unique in that she has access to insurance data inaccessible to researchers. Panjabi (2004) revealed that forces as low as 3.5g impacts would lead to damage to the front of the disc, and 6.5g and 8g impacts would lead to disc damage posteriorly where the neurological components are.

Diagnosis for Disc and Ligament Injuries


A spinal biomechanical expert can look for evidence that is conclusive by disc and pathology, according to two phenomena. First, it is recognized that the body is electric. We’re measuring activity to diagnose when an EMG is done. Second, there are bioelectrical fields in all tissues. This typical field is disrupted when an injury occurs, and in the case of joints calcium is drawn to the damaged tissue. Issacson and Bloebaum (2010) reported “The particular loading pattern of bone has been documented as a significant piezoelectric parameter since potential gaps in bone have been known to be due to charge displacement during the deformation period” (p. 1271). For the patient, we have the ability to tell just how much of this process has occurred before or after their crash, especially if we take into consideration the tissue damage and signs of bone/calcium deposition.

In addition, the body begins a healing process that includes regeneration and remodeling of the soft and hard tissue as reported by Issacson and Bloebaum (2010). Spinal vertebrae have a unique structure of bone which allows it to adapt to abnormal mobility and stability (injury) by changing shape, which can be found on radiographs or MRI. Moreover, shape will change according to patterns based on the pressure or load it undergoes post-injury. Issacson and Bloebaum stated that “Physical forces exerted on a bone change bone structure and is a well-established principle…” (p. 1271). This is a further understanding of a scientific principle called Wolff’s law established in the 1800’s. Because we know what “normal” is, when we see “abnormal” findings as a result of mechanical stress we could broach the topic of an acute injury versus a degenerative process being the cause of the abnormality and create specific medical predictions accordingly.

He and Xinghua (2006) studied the predictability of the bone remodeling process and were able to make predictions of pathological changes that will occur in bone, specifically the osteophyte (bone spur) on the edge of a bone structure. Significantly, they noted their findings “confirmed that osteophyte formation was an adaptive process in response to this change of mechanical environment”. They noted that factors are crucial to the morphology of bones, particularly bones such as the femur and vertebrae.

For readers familiar with current academic and medical accepted nomenclature for disc injury, recognized from the combined task forces of the North American Spine Society (NASS), the American Society of Spine Radiology (ASSR) and the American Society of Neuroradiology (ASNR), disc herniations must have a directional component. When this occurs, the additional and abnormal pressure at the level of the disc damage matched with the direction of the herniation will cause that section of the vertebrae.

Thus, if there’s a C5/6 right sided herniation (protrusion/extrusion) secondary to a cervical acceleration/deceleration injury, then only that side of the vertebrae will change shape, creating an osteophyte. Facet arthritis is additionally caused by this compounded loading on the facet joint. This process is very similar to the formation of a callous on your hand or foot. The callous is a recognized and expected tissue response to increased load/friction exposure. Similarly, an osteophyte is a known and anticipated bone response to a rise in load/friction exposure.

At a basic level, the body has an electrical and mechanical response to injury leading to additional stress that leads to calcium (bone) to flow in the region of injury to further support the joint. The joint then abnormally grows, developing a called hypertrophy, degeneration, disc osteophyte complex, or arthritis/arthropathy, common terms seen in the reports of doctor and radiology.

Everybody is subject to these morphological (structural) changes, always and predictably determined by mechanical imbalances in the spine. He and Xinghua (2006) concluded that, “…it will actually take about over half a year to discover the bone morphological changes…” (p. 101). This indicates that it takes approximately six months to get an osteophyte (bone spur) to be demonstrable post-mechanical breakdown or failure. This again provides a time frame to better understand whether pathology of the intervertebral disc has been present for a long period of time (pre-existing) or has been produced as the direct result of the specific traumatic event by deficiency of the existence of an osteophyte, meaning the disc pathology is less than six months old, dependent on location and management of the pathology.

Conclusion


In conclusion, that by definition, a disc is a ligament connecting a bone to a bone and it has the structural responsibility to the vertebrae above and below to maintain the spinal system in equilibrium. Damage to the disc because of a tear (herniation or annular fissure) or a bulge will create abnormal load-bearing forces in the injury site. These present differently based on [1] if traumatic failure on the side of the disc lesion, or [2] if age related, as a general complex. Since other research and human subject crash testing have defined the term “violent trauma” as not being dependent upon the amount of damage done to the vehicle but rather to the forces to which the neck and head are exposed, we can now accurately predict in a demonstrable way the timing of causality of this disc lesion. This depends upon the symptomatology of the the morphology of the structure and is a subject that can be predicated upon speculation or rhetoric.

Additional Topics: Weakened Ligaments After Whiplash


Whiplash is a commonly reported injury after an individual has been involved in an automobile accident. During an auto accident, the sheer force of the impact often causes the head and neck of the victim to jerk abruptly, back-and-forth, causing damage to the complex structures surrounding the cervical spine. Chiropractic care is a safe and effective, alternative treatment option utilized to help decrease the symptoms of whiplash.

Pain in the Quadratus Lumborum Muscle

A majority of the population have at some point experienced low back pain in their lifetimes. Although low back pain is recognized to result from numerous conditions or injuries on the lumbar spine, muscle strains such as a quadratus lumborum muscle strain, are believed to be a leading cause for the recognizable symptoms of pain and discomfort.
The quadratus lumborum muscle is a sizable muscle in the shape of a triangle, located deep on each respective side of the lower back. The role of the wide muscular tissue is to grant mobility to the lumbar spine in sequence for the torso to move laterally from side to side as well as extend and stabilize the lower spine to improve posture. When this muscle is strained or pulled, the symptoms can restrict movement on the lower back and since the muscular tissue is so extensive, recovery from this type of injury usually requires more time and patience to fully heal.

Achilles Tendon Injury

Achilles tendonitis is a medical term used to describe a condition resulting in irritation of the large tendon, the Achilles tendon. Found in the back of the ankle, this condition is recognized as a common cause for injury among athletes. Excessive use of the Achilles tendon results in inflammation together with swelling and pain.
The development of Achilles tendonitis can be associated with two important factors, most frequently among athletes, which are, lack of flexibility and over-pronation. With age, the tendons will begin to lose flexibility, just the same as other tissues in the body. This change causes the tendons to become more rigid and more vulnerable to injury. For some people, the ankle may roll too far downward and inward with each step they take. This is called over-pronation, which places more stress on the tendons and ligaments of the foot, contributing to injury if not corrected.
Achilles tendonitis may also develop from other factors. An increase in an athlete’s …

5 Common Causes for Shoulder Pain

The shoulders are the most mobile joints in the human body. Because the ball of the humerus is designed to be larger than the shoulder socket that holds it, the shoulders need to be supported by muscles, tendons, and ligaments to secure them in a stable or natural position. Since the shoulder can be unstable, it is often a site for many common complications. Below are 5 common causes of shoulder pain and their associated symptoms.
Rotator Cuff Tear
Rotator cuff tears within the shoulder are a very common type of shoulder injury. The rotator cuff consists of a set of four muscles: the supraspinatus, the infraspinatus, the subscapularis, and the teres minor. All of these muscles are attached to the bones of the shoulders by tendons, which purspose is to support, stabilize, and grant the arm movement to move up, down and rotate. The rotator cuff ensures that the arm remains in the shoulder socket. Damage or injury from an accident or gradual wear and tear can result in inflammation to t…
