Exploring the Efficacy of Autologous Platelet Leukocyte Rich Plasma Injections in Chronic Low Back Pain & Understanding Degenerative Lumbar Spinal Stenosis
Host David Rosenblum, MD
Episode Date: October 25, 2024
In this episode, Dr. David Rosenblum discusses two significant studies related to chronic low back pain and degenerative lumbar conditions. The first study focuses on the use of autologous platelet leukocyte rich plasma (PLRP) injections for treating atrophied lumbar multifidus muscles, while the second study investigates the correlation between muscle atrophy and the severity of degenerative lumbar spinal stenosis (DLSS).
Featured Article 1:
- Effect of Autologous Platelet Leukocyte Rich Plasma Injections on Atrophied Lumbar Multifidus Muscle in Low Back Pain Patients with Monosegmental Degenerative Disc Disease
- **Authors:** Mohamed Hussein, Tamer Hussein
Key Points Discussed
1. Background: Correlation between lumbar multifidus muscle dysfunction and chronic low back pain.
2. Study Overview: 115 patients treated with weekly PLRP injections for six weeks, followed for 24 months.
3. Outcome Measures: Significant improvements in NRS and ODI scores, with high patient satisfaction.
4. Conclusions: PLRP injections into the atrophied multifidus muscle are safe and effective for managing chronic low back pain.
Featured Article 2:
- Degenerative Lumbar Spinal Stenosis
Authors:* Gen Xia, Xueru Li, Yanbing Shang, Bin Fu, Feng Jiang, Huan Liu, Yongdong Qiao
Key Points Discussed
1. Background: DLSS is a common condition in older adults, often leading to muscle atrophy and disability.
2. Study Overview: A retrospective analysis involving 232 patients to investigate the correlation between muscle atrophy and spinal stenosis severity.
3. Results:
- Significant differences in the ratio of fat-free multifidus muscle cross-sectional area between stenotic and non-stenotic segments.
- A strong positive correlation was found between multifidus atrophy and the severity of spinal stenosis.
- The atrophy was more pronounced on symptomatic sides of the spine compared to contralateral sides.
4. Conclusions: The findings suggest that more severe spinal stenosis is associated with greater muscle atrophy, emphasizing the importance of addressing muscle health in DLSS patients.
Discussion:
Dr. Rosenblum provides insights into how these studies inform clinical practices for treating chronic low back pain and managing degenerative conditions. He emphasizes the need for comprehensive treatment strategies that consider both muscle health and spinal integrity which may be achieved via peripheral nerve stimulation of the medial branch nerve and multifidus muscle or PRP injection in to the multifidus muscle.
Closing Remarks:
Listeners are encouraged to stay informed about innovative treatment options and the importance of muscle assessment in managing spinal disorders.

Dr. Rosenblum reviews the benefits of Scrambler Therapy for CRPS and Neuropathic Pain State.
ST was introduced as a chronic pain relief method in 2003. That same year, Giuseppe Marineo published findings from a small clinical trial involving 11 terminal cancer patients suffering from drug-resistant chronic visceral pain, with all participants showing positive responses and significant reductions in pain scores. In a subsequent trial involving 226 patients with neuropathic pain, 80% reported a 50% reduction in pain. Since then, numerous case reports and studies have documented the use of ST for various pain types.
Evidence from these reports suggests that ST is effective for managing both acute and chronic pain from different causes. For instance, a child with acute mixed pain, resistant to pharmacological treatment, experienced significant relief after four ST sessions, with pain levels dropping from 5/10 to 0/10. Additionally, a 52-year-old woman with burning pain from her foot to knee, stemming from a right medullary acute hemorrhage and suffering for 12 years, reported immediate relief after ST. Her pain score decreased from 9/10 to 3/10 on the first day, and to 0/10 by the second day, remaining below 1 on the Visual Analog Scale (VAS) throughout the 10-day treatment period.
In terms of chronic pain, literature includes a case where a patient with shoulder joint pain and limited range of motion saw significant pain reduction and increased mobility after 10 sessions of ST. ST has shown considerable promise in treating severe pain conditions that are typically difficult to manage, such as complex regional pain syndrome and pain related to HIV.
Despite the encouraging results from these case studies, higher-quality evidence is necessary to establish the efficacy of ST, which could be obtained through extensive clinical trials, particularly focusing on chronic pain. Besides the aforementioned studies by Marineo and Sabato et al, additional trials have indicated that ST is an effective treatment for various chronic pain conditions, including low back pain, postherpetic pain, and neuropathic pain. For instance, a prospective study on chronic low back pain patients showed a significant decrease in VAS scores from 8.12 to 3.63 after six treatment days. Another trial involving 10 patients with postherpetic pain reported a drop in the average Numeric Rating Scale (NRS-11) score from 7.64 to 1.46 at baseline and 0.42 to 0.89 after one month, with benefits persisting at two and three months.
ST has also demonstrated significant potential in treating neuropathic pain. In a prospective study of 45 patients with neuropathic pain lasting over three months, 28 experienced a decrease in Douleur Neuropathique en 4 questions (DN4) pain scores, with four patients stopping treatment early due to complete pain resolution. The mean baseline DN4 score dropped from 5.67 to 2.82 by the end of treatment. A pilot randomized trial involving 52 patients found that 21 out of 26 in the intervention group achieved complete pain relief.
While the findings from these studies, along with others that have been systematically analyzed, suggest strong evidence for the efficacy of ST, a definitive conclusion regarding its effectiveness has not yet been reached. A systematic review by Majithia et al concluded that while studies generally indicate ST results in pain reduction with lasting benefits, there are still gaps in the evidence.
This article aims to evaluate the research needs surrounding ST for cancer pain management. While Majithia et al focused on chronic pain across various conditions and noted specific evidence limitations, this study will concentrate on the effectiveness of ST for cancer-related pain. The objective is to identify gaps in the existing literature and provide recommendations for future research through a systematic review. We will specifically analyze the types and levels of evidence supporting the use of ST in managing cancer pain and determine what studies are necessary to enhance the evidence base.
