You have found yourself smack dab in the middle of Episode #257 Now if you missed last week’s episode , we talked about Aspirin And Fall Risk & Caffeine And Child Growth. Make sure you don’t miss that info. Keep up with the class.

On the personal end of things….. What’s going on with me lately? Well, still riding some inflation and recession stuff here these last two months and working on marketing and my customer experience to right the ship as quickly as possible. My trip to Florida and Thanksgiving are playing hell with some of the recoveries but that is what it is and that’s OK. That’s life.

One of the things we started last week was ‘Your benefits re-start in January so use them while you have them.” Also, am I in too big of a hurry with patients?

Do they feel my need to be in and out or do they each feel special in some way? I am trying to slow down and be more present with each patient. More interested in them and in their story. We can always blame outward forces when our practices slow up a bit. And that’s legit. You have to consider all aspects. Is it the economy? My website SEO? Inflation? What is the outward cause?

But also, what are the potential in-house causes? Am I too rushed? Am I no longer focused on the customer experience and only focusing on all of my stuff that has to be done instead? Is there something going on with our new patient process and our booking procedures? Internally, have we changed anything about how we are functioning and doing things? Let’s review how we’re doing things and let’s figure it out. That’s what I’m looking at right now.

No coach or mastermind has all of the answers to a slowdown. It is up to us as business owners to diagnose the cause and the effect. At least to the best of our abilities. I’m not dramatically slower than in August but September and October and November have been slow enough compared to my regular load that it’s past time to get it fixed and headed back in the right direction.

And that includes looking in the mirror. We should all do that. A good leader doesn’t ask where the staff failed, but asks, where have I failed. That’s what I’m doing.

Also, I’m looking at where I can delegate tasks that have put me in a hurry most days. When I can’t keep up with stuff, it’s time to figure out how to farm out stuff so that I don’t feel rushed and overwhelmed all day every day. I’m an immaculate stat keeper. That’s about to change. I have an excellent virtual assistant in Nigeria that is helping me figure out how to automate and delegate balancing bank statements, which I still do myself and stat keeping.

This will save A LOT of time on Mondays, Tuesdays, and Wednesdays freeing my brain up to work on more productive tasks like the customer experience. Alright, enough introspective discovery for this week. Onto the research.

Item #1

The first on today is called, “Vertebral arteries do not experience tensile force during manual cervical spine manipulation applied to human cadavers” by Gorrell et. al. (Gorrell LM 2022) and published in Journal of Manual Manipulativer Therapy on November 15, 2022. Dayum. That’s hot.

Why They Did It The vertebral artery (VA) may be stretched and subsequently damaged during manual cervical spine manipulation. The objective of this study was to measure vertebral artery length changes that occur during cervical spine manipulation and to compare these to the vertebral artery failure length.

How They Did It

• Piezoelectric ultrasound crystals were implanted along the length of the VA (C1 to C7) and were used to measure length changes during cervical spine manipulation of seven un-embalmed, post-rigor human cadavers.
• Arteries were then excised, and elongation from arbitrary in-situ head/neck positions to first force (0.1 N) was measured. Following this, vertebral arteries were stretched (8.33 mm/s) to mechanical failure.
• Failure was defined as the instance when VA elongation resulted in a decrease in force.

What They Found

• From arbitrary in-situ head/neck positions, the greatest average vertebral artery length change during spinal manipulation was 5.1%.
• From arbitrary in-situ head/neck positions, arteries were elongated on average 33.5% prior to first force occurrence and 51.3% to failure.
• Average failure forces were 3.4 N

Wrap It Up

Measured in arbitrary in-situ head/neck positions, vertebral arteries were slack. It appears that this slack must be taken up prior to vertebral arteries experiencing tensile force. During cervical spine manipulations (using cervical spine extension and rotation), arterial length changes remained below that slack length, suggesting that VA elongated but were not stretched during the manipulation.

Item #2

Our last one this week is called, “The Relationship Between Physical Activity and Pain in U.S. Adults” by Ray et. al. (Ray 2022) and published in Medicine and Science in Sports and Exercise on October 26, 2022. Hot potato!

Why They Did It The authors wanted to assess the relationship between physical activity (PA) and pain within the available sample, with secondary aims to assess prevalence of pain, physical activity levels, healthcare seeking behaviors, and impact of pain on daily activities and work.

How They Did It They conducted an epidemiological cross-sectional observational study utilizing National Health Interview Survey (NHIS) data from 2020. They examined the self-reported adherence to current physical activity guidelines and the prevalence of pain. They hypothesized those dealing with pain were less likely to meet physical activity guidelines. physical activity levels, pain prevalence, frequency, and intensity were assessed via the survey and relationships explored via modeling.

What They Found

• 31,568, subjects
• 12,429 (39.37%) reported pain on some days, 2,761 (8.75%) on most days, and 4,661 (14.76%) every day.
• The odds of engaging in physical activity decreased in a stepwise fashion based on frequency and intensity of pain reporting when compared to no pain.
• Importantly, physical activity is a significant correlate affecting pain reporting, with individuals engaging in physical activity (strength and aerobic) demonstrating 2 times lower odds of reporting pain when compared to those not meeting the physical activity guidelines.

Wrap It Up

There is a significant correlation between meeting physical activity guidelines and pain. Meeting both criteria of physical activity guidelines resulted in lower odds of reporting pain. Additionally, the odds of participating in physical activity decreased based on pain frequency reporting.

These are important findings for clinicians, highlighting the need for assessing physical activity not only for those dealing with pain but as a potential risk factor for minimizing the development of chronic pain. Get ‘em moving folks!

Alright, that’s it. Keep on keepin’ on. Keep changing our profession from your corner of the world. The world needs evidence-based, patient-centered practitioners driving the bus. The profession needs us in the ACA and involved in leadership of state associations. So quit griping about the profession if you’re doing nothing to make it better. Get active, get involved, and make it happen. Let’s get to the message. Same as it is every week. Store Remember the evidence-informed brochures and posters at chiropracticforward.com.

Purchase Dr. Williams’s book, a perfect educational tool and chiropractic research reference for the daily practitioner, from the Amazon store TODAY!

The Message I want you to know with absolute certainty that when Chiropractic is at its best, you can’t beat the risk vs reward ratio because spinal pain is primarily a movement-related pain and typically responds better to movement-related treatment rather than chemical treatments like pills and shots. When compared to the traditional medical model, research and clinical experience show us patients can get good to excellent results for headaches, neck pain, back pain, and joint pain to name just a few. It’s safe and cost-effective can decrease surgeries & disability and we do it through conservative, non-surgical means with minimal hassle to the patient. And, if the patient treats preventatively after initial recovery, we can usually keep it that way while raising the overall level of health!

Key Point: At the end of the day, patients should have the guarantee of having the best treatment that offers the least harm. When it comes to non-complicated musculoskeletal complaints…. That’s Chiropractic!
