Body Armor and Lumbar Disc Herniation in Young Military Veterans: A Case Series.

INTRODUCTION: Soldiers on the battlefield are affected by heavy body armor and excessive march load. It is well known, but the long-term effects of this extra weight on the musculoskeletal system of military veterans, specifically the lumbar spine, are unclear. In Iraq and Afghanistan, most body armors weighed over 33 pounds (15 kg). These armors were 3 times heavier than those used in Vietnam. Chiropractors at the Fargo VA Hospital are seeing more young veterans with non-traumatic lower back pain. This article presents a perspective on the impact of body armor weight and excessive carry load on lumbosacral disc herniation with radicular pain in military veterans. MATERIALS AND METHODS: This study is a retrospective case series. We used a convenient sampling method. We selected the first 10 military veterans who came to a Fargo VA chiropractor in late fall 2023. Each veteran filled out a VA Form 10-5345 to give us permission to access their electronic health records. All 10 veterans also completed a survey. The survey asked about their active combat status, the type and weight of their body armor, how long they wore the armor each day, how much weight they carried, and their opinion on the cause of their lower back pain (service related or not). The Fargo VA does not require an institutional review board for a case series. RESULTS: This study found that military veterans experience lower back pain at an average age of 35 years. This is at least 5 years earlier than non-service men. Lower back pain with disc herniation typically occurs at the L4-L5 and L5-S1 disc levels. All 10 veterans in the study believe that their lower back pain is related to their service. Sixty percent of the participants in the study have a service-connected disability because of back pain. CONCLUSIONS: For military veterans, onset of lower back pain from a disc herniation at a young age may be linked to carrying heavy body armor and loads. However, the small sample size of this case series limits causal relationship inferences.

Chiropractic Care of a Female Veteran After Cervical Total Disk Replacement: A Case Report.

Objective: The purpose of this case study is to describe chiropractic care of the cervical spine for a patient who previously underwent cervical total disk replacement (CTDR) of the C5-6 and C6-7 disks. Clinical Features: A 42-year-old female veteran of the U.S. Army presented to a Veterans Affairs chiropractic clinic with chronic cervical pain and radiculopathy. She had previously undergone CTDR surgery of the C5-6 disk 9 years earlier, but the pain had become severe and radicular symptoms had returned in the upper left extremity. Imaging taken before the chiropractic referral demonstrated significant joint space narrowing and disk herniation of the C6-7 disk with protrusion to the left side. Intervention and Outcome: The patient received spinal manipulative therapy, trigger-point therapy, and manual traction to the cervical spine. However, these treatments were not effective in reducing her cervical pain and radiculopathy. She then opted for CTDR of the C6-7 disk. After surgery, the patient reported that radicular symptoms were mostly relieved and cervical pain had decreased by 50%. After 6 additional spinal manipulative therapy treatments, she reported having no neurologic symptoms and that her pain had decreased more than 70% from presurgery levels. Conclusion: This case report is the first reported example of chiropractic care after CTDR within an integrated health care environment. The patient's cervical pain and radiculopathy improved with CTDR along with postsurgical chiropractic care.

Combination Acupuncture and Cupping for Treating Adult Idiopathic Scoliosis.

Background: There is limited previous English-language literature on acupuncture's ability to treat idiopathic scoliosis. This report shows the potential effectiveness of a combination of acupuncture and cupping therapies to treat curvature progression and thoracic back pain in adult idiopathic scoliosis. Intervention: A 34-year-old male veteran of the U.S. Armed Forces with thoracic back pain and muscle spasms originally presented to the chiropractic clinic at the Fargo Veterans Affairs Healthcare System, Fargo, ND. Per radiographs taken prior to the consultation, the chiropractor determined that the patient had an idiopathic right-convex scoliosis curve of ∼21°. Due to immobility of the thoracic spinal vertebra upon adjustment, he was referred to acupuncture care. After a clinical review, the acupuncturist hypothesized that a combination of utilizing acupuncture and cupping techniques would help relax the muscles along the thoracic spine, allowing correction of the patient's abnormal spinal curvature. Combination Traditional Chinese Medicine (TCM), using acupuncture with cupping therapy was given ∼2 times per week for several weeks, resulting in a total of 15 treatments. Results: After 15 treatments, this patient's subjective pain decreased by 85%. Anecdotally, he reported "feeling a bit looser." He continued to receive acupuncture and cupping treatments when his schedule allowed. Conclusions: The combination therapy was effective for treating musculoskeletal pain but was inconclusive with respect to its ability to treat adult idiopathic scoliosis. More research is needed on the efficacy of TCM for treating adult idiopathic scoliosis.

Bandwidth extension of intensity-based sound power estimates.

The traditional method for intensity-based sound power estimates often used in engineering applications is limited in bandwidth by microphone phase mismatch at low frequencies and by microphone spacing at high frequencies. To overcome these limitations, the Phase and Amplitude Gradient Estimator (PAGE) method [Gee, Neilsen, Sommerfeldt, Akamine, and Okamoto, J. Acoust. Soc. Am. 141(4), EL357-EL362 (2017)] is applied to sound power for a reference sound source, a blender, and a vacuum cleaner. Sound power measurements taken according to ISO 3741:2010 (2010) are compared against traditional- and PAGE-processed intensity-based sound power estimates measured according to ANSI S12.12-1992 (R2017). While the traditional method underestimates the sound power at the spatial Nyquist frequency by 7-10 dB, the PAGE-based sound power is accurate up to the spatial Nyquist frequency, and above when phase unwrapping is successful.
