Reflex Sympathetic Dystrophy: Factors and Influences Involved in Symptom Migration
by Robert E. Fulwiler

 


 
I. Introduction

Statement of Purpose
The purpose of this study is to investigate the relationships that exist among certain variables as they relate to the spread of the symptoms of Reflex Sympathetic Dystrophy. The variables include type of causal event, age at time of symptom onset, duration of time from symptom onset, mitigating or aggravating medical procedures, and any additional injury.

Significance
A common complaint of sufferers of Reflex Sympathetic Dystrophy is that they have been told that "it's all in your head". A physician, unable to see an outward manifestation of injury, may be prone to ascribe the pain to the mind rather than to the body of his or her Reflex Sympathetic Dystrophy patient. It is far easier for a doctor to diagnose and treat an obvious injury, such as a broken limb, than to make a difficult diagnosis based primarily upon the fact that the patient complains of pain. Treating the pain is treating Reflex Sympathetic Dystrophy. And sometimes treating the pain does more harm than good. This research paper is intended to contribute to the general body of knowledge concerning the timing, causation, and conditions involved in the spread of the symptoms of Reflex Sympathetic Dystrophy. Particular attention will be paid to the possibility that there is a pattern to the events and circumstances that lead to a bilateral symptom condition.

 

 

II. Literature Review

Definition and Description of Reflex Sympathetic Dystrophy
The first description of the condition now known as Reflex Sympathetic Dystrophy is credited to Dr. Silas Weir Mitchell. He and his associates performed several studies based on the treatment of Civil War soldiers who had suffered gunshot wounds or nerve injuries. (Raja & Hendler, 1990). Dr. Mitchell defined the condition as causalgia, which he described as a burning pain. (van der Laan & Goris, 1997).

In 1916, Dr. R. Leriche first described the pathophysiology of Reflex Sympathetic Dystrophy. (van der Laan & Goris, 1997).

Dr. Leriche was the first physician to describe the connection between an altered sympathetic nervous system and the pain known as causalgia. (Raja & Hendler, 1990).

Dr. W. K. Livingston suggested that Reflex Sympathetic Dystrophy resulted from a cycle in which the interaction of the sympathetic nervous system and pain source develops into a chronic excitation of the spinal column. (van der Laan & Goris, 1997).

Dr. Paul Sudeck proposed the idea that Reflex Sympathetic Dystrophy was an exaggerated response to nerve damage or soft tissue injury. Reflex Sympathetic Dystrophy is also known as Sudeck's Atrophy as a result of his work in this specialty. (Veldman & Jacobs, 1994).

Dr. Sudeck documented the loss of bone mass in patients suffering from Reflex Sympathetic Dystrophy. (Paice, 1995).

The International Association for the Study of Pain decided that causalgia and Reflex Sympathetic Dystrophy differed enough to be split into two disorders. In 1994, they renamed Reflex Sympathetic Dystrophy to Complex Regional Pain Syndrome Type I and causalgia to Complex Regional Pain Syndrome Type II. The difference between these two conditions is that there is a definable nerve injury present in Complex Regional Pain Syndrome Type II. (Simmons, 1998).

Reflex Sympathetic Dystrophy normally occurs as a result of surgery or injury to a limb. Its symptoms can include unexplained diffuse pain, changes in skin color, temperature differences between affected and unaffected areas, limited range of motion, swelling, symptoms that appear in areas not injured, decrease in bone density, and increased symptom severity after exercise of the affected area. It is considered to be a major cause of disability in that only twenty percent of Reflex Sympathetic Dystrophy patients are able to resume all life activities. The most common symptom of Reflex Sympathetic Dystrophy is pain. (Veldman, Reynen, Arntz, & Goris, 1993).

There are three stages normally associated with Reflex Sympathetic Dystrophy. The first stage is referred to as the acute stage. Pain is more than what would be considered normal for the insult or injury. The affected area is either too warm or too cold and is extremely sensitive to movement and touch. Patients may avoid using an affected limb. The second stage is known as the dystrophic stage. The pain becomes more severe and diffuse. The patient is likely to suffer hair loss in the affected area and nails become brittle and grooved. Muscle wasting and bone density loss begins. Some patients experience a noticeable temperature drop and diminished blood flow in the affected area or limb. Psychological and emotional problems can occur due to the worsening of symptoms and lack of improvement. The third stage is known as the atrophic stage. At this point, the pain is widespread and intractable. Irreversible tissue change occurs during this stage. Ligament and muscle problems may create a condition in which the patient loses meaningful use of the limb. Hair loss in the affected area becomes more pronounced and the skin often takes on a shiny or smooth look. The patient is in constant pain and may experience additional psychological and emotional difficulties. (Scarano & Shrager, 1994).

Diagnostics and Reflex Sympathetic Dystrophy
Many doctors have attempted to develop a methodology with which to make a diagnosis of Reflex Sympathetic Dystrophy. Diagnostic considerations have included thermography, bone scans, measures of blood flows, changes in mobility, vasomotor changes, and even psychological testing. (Ochoa, 1997). Some doctors are hesitant to issue a diagnosis of Reflex Sympathetic Dystrophy because of the diagnostic difficulties of associated with a disease that can exhibit such varied and changing symptoms. Other physicians apparently err in the other direction by deciding that any patient complaining of symptoms similar to those of Reflex Sympathetic Dystrophy must be suffering from this condition. (Olmos, 1998). The only generally accepted diagnostic indication of Reflex Sympathetic Dystrophy is a positive response to a sympathetic block. (Weiss, 1994). Sympathetic blocks are usually accomplished via injection of a local anesthetic to the stellate ganglion in the neck of the patient. (Raja & Hendler, 1990).

Prognosis and Treatment for Reflex Sympathetic Dystrophy Patients
Patients may recover from Reflex Sympathetic Dystrophy. Spontaneous recoveries are rare. Best results occur when there is an early diagnosis and aggressive treatment. Sympathetic blocks and sympathectomies are widely used to treat Reflex Sympathetic Dystrophy. (Raja & Hendler, 1990). Additional forms of treatment include physical therapy, psychotherapy, biofeedback training, and use of various drugs including corticosteroids, calcium channel blockers, anti-convulsants, opiods, anti-inflammatories, and antidepressants. (Stanton-Hicks, Baron, Boas, Gordh, Harden, Hendler, Koltzenburg, Raj, & Wilder, 1998). The long-term prognosis is not encouraging. Some studies have indicated that as many as two-thirds of Reflex Sympathetic Dystrophy patients experience the spread of symptoms into more than one limb. (Schaffer, 1997). It is not uncommon for Reflex Sympathetic Dystrophy to progress to a final or fourth stage in which the patient may develop global symptoms including intractable hypertension, generalized edema, skin lesions, and a weakened immune system. (Hooshmand, 1997).

 

III. RESEARCH QUESTION

Major Question:
What are the factors involved in the migration of symptoms experienced by persons diagnosed as having the medical condition known as Reflex Sympathetic Dystrophy?

Related Questions:
1. Is there a different pattern associated with age at symptom onset?
2. Was the migration of symptoms the result of an additional insult or injury?
3. In what portion of the patient population have the symptoms spread in a bilateral fashion?
4. Are the participants able to provide anecdotal information that provides additional insight into causes, patterns, or other variables as they relate to symptom migration?

 

IV. METHODOLOGY

Sample
This study targeted persons diagnosed as having the medical condition known as Reflex Sympathetic Dystrophy. Limited time and resources dictated the use of a convenience survey. Permission was obtained to use the membership mailing list of the Reflex Sympathetic Dystrophy/Complex Regional Pain Syndrome Association of North Texas. Additional addresses were obtained from public records and private correspondence. A total of ninety-eight (98) surveys were mailed to the persons on the combined mailing list.

Instrumentation
This descriptive study was accomplished by use of a questionnaire. The elements presented on the survey were developed from a review of the literature and the expertise of the researcher. The questionnaire contained ten questions. The first two questions concerned demographic considerations of sex and age. Two questions were selection questions with an additional area for other comment. One question requested the participant to select an age range. Three questions requested a yes or no response. Two questions were in a fill in the blank format.

A large comment section was included as the last item on the survey. A copy of the questionnaire appears in Appendix B.

Study Design
The research question addressed by this study resulted from inquiries made to the telephone response team of the Reflex Sympathetic Dystrophy/Complex Regional Pain Syndrome Association of North Texas. A review of the available literature indicated that this topic had not previously been researched in depth. A thorough research of materials available already in the possession of the researcher indicated a need for additional information. A search of the periodicals database at the Plano Public Library provided thirteen references to Reflex Sympathetic Dystrophy. These documents were obtained and used to complete a review of the current literature on the topic of choice.

A survey was designed so as to obtain responses concerning Reflex Sympathetic Dystrophy symptom migration and the variables associated with this phenomenon. The questionnaire was pretested and no problems were encountered. Ninety-eight mailings were made to persons known to the researcher to have Reflex Sympathetic Dystrophy and others listed on the member mailing list of the Reflex Sympathetic Dystrophy/Complex Regional Pain Syndrome Association of North Texas. The selection of these participants was based on the fact that a convenience sampling was necessitated by a lack of the time and resources that would have been required to obtain a more statistically appropriate sample population. Mailings included the survey and a stamped, self-addressed envelope. Thirty-nine questionnaires were returned and processed. The conclusions presented in this research are the result of the analysis of the twenty surveys that were completed and returned.

Data Analysis
Descriptive statistics, to include percentages, counts, and graphs, will be used to analyze and describe the results of the survey used in this research. Selected responses to open-ended questions and selected comments will be reported as anecdotal information and will be included appear in Appendix D of this document.

 

V. RESULTS

Ninety-eight questionnaires were mailed to potential participants. Ten were returned as undeliverable. One envelope came back empty. One participant returned the survey with a letter explaining that her diagnosis had changed and she did not have Reflex Sympathetic Dystrophy. Thirty-nine surveys were completed and returned for a response rate of 39.8%. Six of the respondents were male and thirty-three were female. The ages of the respondents are as follows: 5.13% were 15 to 19 years, 2.56% were 20 to 24 years, 17.95% were 30 to 34 years, 7.69% were 35 to 39 years, 12.82% were 40 to 44 years, 28.21% were 45 to 49 years, 7.69% were 50 to 54 years, 10.26% were 55 to 59 years, and 7.69% were over 59 years. 64.10% of the participants indicated that their Reflex Sympathetic Dystrophy was the result of an injury, 23.08% indicated their condition resulted from surgery, 10.26% indicated their condition resulted from a combination of injury and surgery, and 2.56% indicated that something other than injury or surgery caused their condition. The ages of the participants at symptom onset are as follows: 5.13% were 14 years or younger, 5.13% were 20 to 24 years, 15.38% were 25 to 29 years, 7.69% were 30 to 34 years, 17.95% were 35 to 39 years, 15.38% were 40 to 44 years, 17.95% were 45 to 49 years, 10.26% were 50 to 54 years, 2.56% were 55 to 59 years, and 2.56% were over 59 years. The average elapsed time since initial diagnosis was 69.88 months. The average elapsed time from symptom onset to diagnosis was 14.06 months. 82.05% of participants reported that their Reflex Sympathetic Dystrophy symptoms had spread. 17.95% of participants reported no spreading of symptoms. Of those respondents reporting symptom spread, 15.63% reported this to be a result of injury, 28.13% reported this to be a result of surgery, 21.88% reported this to be a result of both injury and surgery, and 34.38% responded by selecting "Other". Of the sixteen participants reporting symptom spread to be the result of surgery, or a combination of injury and surgery, five indicated that the surgery was related to Carpal Tunnel Syndrome. Of the thirty-two participants that experienced symptom spread, 68.75% of the participants reported bilateral symptom spread, 21.88% of participants indicated no bilateral symptom spread, and 9.37% did not answer the question. 69.23% of the participants provided additional information in the comment section. 46.15% of the participants provided additional information in the areas designated for explanation of an answer of "Other". Graphical representations of analyzed response data is provided in Appendix C.

 

CONCLUSION

Conclusions
The data collected by this research project has caused the researcher to conclude that the symptoms of Reflex Sympathetic Dystrophy are likely to spread as the result of additional injury or an invasive medical procedure. Additionally, this research indicates that bilateral symptom migration is common among Reflex Sympathetic Dystrophy patients. This study indicates the need for additional professional inquiries into the causes of symptom migration and possible treatments to delay, inhibit, or otherwise mitigate this phenomenon.

Limitations
This study suffered from poor sampling technique. Far more significant results could have been obtained by the proper and timely generation of a more random and representative sample population. While no sample is perfect, any improvement in the selection of potential participants increases the generalizability of the research and improves the chances for successful replication of the results.
