Clinical trial NCT02268305
Conditions: Low Back Pain
Sponsor: Mike O'Callaghan Military Hospital
Start date: 2015-02-01; Completion date: 2018-06-05
Enrollment: 100 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
The investigators are studying whether MSM plus standard of care naproxen improves symptoms of lower back pain compared to standard of care naproxen plus placebo. Subjects will be randomized into 1 of 2 groups. Group 1 will take by mouth 6000 milligrams (mgs) of MSM plus standard of care naproxen. Group 2 will take by mouth placebo capsules plus standard of care naproxen. Subjects will be instructed to take their study pills for 12 weeks and record on a study diary. They will then be followed up for one final visit 4 weeks later. RMDQ, PIQ-6, pain level, comprehensive metabolic panel (CMP), complete blood count (CBC) will be assessed at 4 week intervals for 12 weeks. Subjects' participation will last 16 weeks.

Detailed description:
We will recruit male and female MOFMC DoD beneficiaries between the ages of 18-65 years old with symptoms of lower back pain from any of the clinics at the MOFMC at Nellis Air Force Base. Patients taking Muscle relaxers of any type, Non-steroidal anti-inflammatory agents (NSAIDs), Tramadol, Gabapentin, Pregabalin, agree to wash out for two weeks prior to entering the study.

3.  Research Plan:  
 
3.1. Purpose:  
The purpose of this study is to assess whether Methylsulfonylmethane (MSM) plus standard of care naproxen improves 
symptoms of lower back pain versus standard of care naproxen plus placebo. 
 
3.2. Hypotheses, Research Questions or Objectives:  
Does the addition of MSM to standard of care treatment improve symptoms of lower back pain assessed by Roland-Morris 
Disability Questionnaire (RMDQ), pain level, and Pain Impact Questionnaire (PIQ-6)? 
   
3.3.  Significance:  
A lack of true clinical assessment of the usefulness of MSM in low back pain suggests that patients will continue to consume a 
product with a potential but unknown benefit. As a multidimensional approach to the treatment of low back pain is endorsed, 
the assessment of MSM on low back pain as an alternative or adjunctive therapy would be prudent. For this reason, we propose 
that a clinical trial be carried out to assess the impact of MSM on low back pain. 
 
3.4.  Military Relevance81:  
Low back pain is a common complaint of Tricare beneficiaries. In 2012, chronic pain treatment accounted for an approximate 
annual cost of $560-635 billion in direct medical treatment costs and lost productivity in the United States.  Despite these costs, 
the response of each individual to standard treatments varies greatly, often being under treated. Within the military, responses 
to traditional treatments and lost productivity are no different than the civilian communities but may have a far more reaching 
consequence as service men and women are often unable to perform their duties fully or deploy due to pain.  
 
While the DoD has developed tools for physicians to assess and treat low back pain, treatment is not always successful. As such, 
additional treatments options are needed which may yield positive results, without producing adverse side effects which may 
limit a member from duty or deployment. The proposed study of MSM will help define this new potential treatment, specifically 


Version 1: 1 Dec 2012 
Revised by AMD 8 
Non-Exempt Human Research Study 
measuring improvement of pain and function. If found to be effective, this treatment may represent a significant step forward 
in providing excellent care to service members, while ensuring a force which is fit for duty. 
  
3.5.  Background and Review of Literature:  
Background:  Low back pain has been identified to account for 40% of all work related compensations filed in the US1. Overall, 
the lifetime prevalence of experiencing at least one episode of low back pain is believed to be 70-80%1. The etiology of low back 
pain is often considered multidimensional, and as such often requires a multidimensional approach to its treatment2,3.  Even 
when a multidimensional treatment plan is created or proposed for patients, many endorse the concurrent use of 
complementary and alternative medicines, either as adjunctive therapy or in place of offered treatment. This is especially true 
when patients have concerns about the cost or delayed receipt of conventional care4. While the true percent of patients who 
endorse the use of complementary or alternative medicines is unknown, reports suggest that 9% to 65% of the population has or 
currently uses treatments other than those prescribed by their physician5.  Back pain has been noted to be the principle reason 
for using CAM4,6 Top cited uses of CAM include prayer5, nonvitamin, nonmineral, natural products, deep breathing exercises, 
meditation, chiropractic, or osteopathic manipulation, massage, and yoga7.  
 
Sources used by patients for acquiring information on various CAM therapies vary from internet, to personal testimonial, to 
books published by a variety of health professionals.  Among the many published books, H procumbens, S alba, topical capsasin 
compresses, and methylsulfonylmethane (MSM) are often cited as a supplemental agent which can be used for a variety of 
orthopedic ailments ranging from arthritis to low back pain8,9.  Specifically, MSM accounts for 4.1% of nonvitamin, nonmineral  
products used4. While several clinical trials and systematic reviews have been aimed at testing H procumbens, S alba, topical 
capsasin compresses for low back pain, clinical trials assessing the role MSM may play in the treatment of low back pain are 
largely lacking. Despite this, it remains widely cited as an agent which may be used in the treatment of low back pain8,10 as well 
as many other illnesses11.    
 
Research of Interest: One area in which MSM has undergone some degree of investigation is its use as an adjunct therapy for 
osteoarthritis12-19.  In each study of patients with OA, MSM was associated with decreased patient pain and increased function. 
Variation in method used to measure effectiveness was noted from study to study, the most frequent assessments used 
including Oswestry Disability Questionnaire,  Roland-Morris Disability Questionnaire, Visual Analogue Scale (for pain intensity), 
and Western Ontario and McMaster University Osteoarthritis Index visual analogue scale (WOMAC).  As pointed out by  We et 
al, the variability of effect found in the use of MSM in osteoarthritis  approaches 0% with studies noting a significant 
improvement in most measured symptoms. This suggests that the effect of MSM has on pain caused by osteoarthritis 
consistently improves symptoms from study to study. Because each study contained various shortcomings in terms of study 
design (small treatment groups, possible un-blinding, questionable open-label trials, possible co-interventions, unstated 
compliance the use of MSM in the treatment of osteoarthritis), MSM has not been recommended for treatment of OA in all 
patients. However, data currently are supportive of its use.  
 
Pharmacology of MSM: Methysulfonylmethane [(CH3)2SO2] is a largely tasteless, odorless, white, crystalline solid which is water 
soluble20. It occurs naturally in the environment and is synthesized in the human body18 as a byproduct of dietary DMSO21 where 
15% of consumed DMSO is converted into MSM 11.  MSM is believed to have anti-inflammatory properties as demonstrated by in-
vitro studies which suggest MSM may blunt inflammatory processes22.  However, studies have demonstrated that MSM does 
not interact with the COX or PG synthesis pathways23 or by decreasing ESR or CRP levels13. While DMSO and MSM are believed to 
block conduction of peripheral C-fibers15, slow the proliferation of smooth muscle and endothelial cells, and decrease the 
binding, uptake, and degradation of LDL by fibroblasts27,28, decrease urine MDA levels in humans, and delay chemically-induced 
colon cancer onset in rats13, no clear anti-inflammatory mechanism of action has been elicited. 
 
While MSM has not received FDA approval for any specific ailment, DMSO, the parent compound of MSM (see above) has been 
FDA approved for the treatment of intersitital cystitis when infused as a 50% solution71. MSM continues to be used (CAM) for 
illnesses including  OA, back pain, fibromyalgia, tendinitis, carpal-tunnel syndrome, dental pain, asthma, food allergies, asthma, 
rheumatoid arthritis, SLE, scleroderma, hypertension, and elevated serum cholesterol among others20,24.  
 
Safety: MSM is rated as “Probably Safe” by the Natural Medicines Comprehensive Database when given in 2.6 to 6 grams/day, 
up to 12 weeks24. Studies in rats given 1.5-2.0 g/kg/day orally showed no mortality, adverse effects or clinical signs of toxicity, 
effects on body weight gain, or gross lesions68.  In a study by Kim et al15 on MSM and osteoarthritis, no change or adverse event 
was noted in liver or renal function, hematology studies (CBC), stool assessment for occult bleeding or lipid profile, or urinalysis.  
In a similar study, Vidyasagar et al78 found similar results with no CBC, Serum Glucose, Urea, Creatinine or AST/ALT. Taking all of 
this into consideration, the FDA previously labeled MSM as Generally Recognized as Safe in 200879. The LD50 is currently 
unknown due to the fact that maximum dose given to date (20g/kg/day) failed to produce death in animal studies69. MSM 
should be avoided during pregnancy and lactation due to insufficient reliable information available (no studies have specifically 


Version 1: 1 Dec 2012 
Revised by AMD 8 
Non-Exempt Human Research Study 
looked at its use during pregnancy). Prior to the recommendation to limiting the daily dose to 6 grams/day in humans, some 
physicians recommended up to 20 g/day, which approximates to 300 mg per kg/day70. 
 
Adverse Reactions13,24: When dosed orally, nausea, diarrhea, bloating, headache, fatigue, insomnia, and difficulty concentrating 
have been reported. These adverse reactions however, do not appear to occur any more frequently in groups exposed to MSM 
than placebo in clinical trials13. There is no known drug-food, drug-drug, or drug-lab test interactions known24. 
 
Proposed use of MSM in Low Back Pain: As noted previously, MSM accounts for 4.1% of all nonvitamin, nonmineral CAM 
therapies used and is often cited as a remedy for back pain.  Tant et al note that in a trial of glucosamine containing MSM, both 
yield symptomatic relief in patients with low back pain, individually and when taken together25.  Interestingly, trials such as that 
performed by Usha et al included MSM in the formulation of Glucosamine when assessing its impact on osteoarthritis14.  
However, additional information on the impact MSM may have on low back pain is lacking. Furthermore, of the 462 trials for low 
back pain registered with clinicaltrials.gov, none is designed to assess the impact of MSM on low back pain26.  
 
Patients continue to access information on CAM through a variety of sources. A lack of true clinical assessment of the usefulness 
of MSM in low back pain suggests that patients will continue to consume a product with a potential but unknown benefit. As a 
multidimensional approach to the treatment of low back pain is endorsed, the assessment of MSM on low back pain as an 
alternative or adjunctive therapy would be prudent. For this reason, we propose that a clinical trial be carried out to assess the 
impact of MSM on low back pain. 
 
Selection of Outcome Measurements in Low Back Pain: Clinical outcome measurements for low back pain have been studied by 
many groups. Reviews of various outcome measurements for low back pain have identified up to 36 distinct outcome 
measurements36. However, only a select number of them are considered valid or reliable. Studies may be unidimensional, 
focusing only on pain, or multidimensional where focus is placed not only on pain but on the extent to which the severity of pain 
impacts activity or emotional function30,35. No Gold Standard exists for evaluating disability in low back pain34 though authors 
suggest that prospective32, patient/self-reported31,33,35 measures of pain are ideal.  Some authors suggest that surrogate markers 
such as analgesic use should not be used when assessing a patient’s clinical status32. However, because the etiology of low back 
pain is often multifactorial, multiple measurements of low back pain are often recommended when measuring the impact any 
given intervention has on low back pain29.  
 
Three general areas of assessment common to low back pain include pain, function, and quality of life29. Of these areas, 
assessment of pain itself is often the focus of studies due to the belief that a prerequisite to the management of pain is the 
accurate assessment of the same47. This focus is further supported by the finding that the correlation between self-reported 
pain and self-reported function and objective measures of function are significant but weak48,49,50. The other areas are assessed 
as they give insight into the overall impact the treatment has on the patient (clinical significance). Studies commonly used to 
assess these areas include: 
 
-Pain: Visual Assessment Scale (VAS)29, 31, 37, Verbal Rating Scales (VRS)32, and Numerical Rating Scale (NRS)32,38 
 
-Function: Oswestry Low Back Pain Disability Questionnaire/Index (ODI) 29,37, Roland-Morris Disability Questionnaire 
(RMDQ)29,37, Quebec Back Pain Disability Scale34,37 
 
-Quality of Life: SF-36, 12, or PIQ-629,35,37,67, Patients Global Assessment of Response to Therapy (PGART)31 
 
Pain: We recommend the VAS. The VAS appears in most studies of low back pain and has specifically been recommended29. 
Mannion et al also suggest that most patients treat the VRS and NRS as a VAS by simplifying each respective numerical scale to 
approximate that seen in the VAS. When the scale is properly explained, it has been shown to be reproducible and easy to 
interpret35. However, this choice may be considered arbitrary as studies measuring the variance between various numerical 
scales suggest any numerical scale may be used with expected reproducible results35. One advantage of using the NRS is that 
the Minimally Clinically Important Difference (MCID) has already been calculated as 235,38. With respect to expected outcomes, 
Farrar suggests that a relative treatment difference in pain level of 33-50% on any scale is considered clinically meaningful40. 
 
Function: We recommend the Roland-Morris Disability Questionnaire. While both the ODI and RMDQ are reliable, valid, and 
require only 5 minutes to complete, the RMDQ is the most studied of all functional outcome assessments35. Published Mean 
Detectable Change (MDC) is available for both of these studies though it varies from study to study, based on the initial 
measured level of function. Generally, a low initial score indicates that less than a 5 point difference is needed to identify a 
detectable change. Higher baseline scores may necessitate as much as a 8-9 point difference to identify a change. Roughly, a 5 
point difference correlates to a 20% change on the scale35. Other authors such as Bombardier et al suggest that a 2-3 point 
difference is a MCID41.

Non-Exempt Human Research Study 
Quality of Life:  We propose the use of the PIQ-6/R. While the SF-36 and SF-12 has been well studied and approved by the 
Medical Outcome Trust51, shorter questionnaires which measure the impact of pain on the quality of life have been developed 
and include the SF-6D and PIQ-6/PIQ-R35,51,67 which may provide reliable information.  While the SF-36 has been more widely 
published35, the SF-12 and PIQ-6/R are routinely used. Limited data has been published on the MDC or MCID for the SF-36 but has 
been described by Walters et al65. The PIQ-6 is ideal for the current study due to its high internal validity and correlation with 
pain visual analog and numerical rating scales67. An additional reason for using the PIQ-6 rather than the SF-6 includes concerns 
that the SF-6 may overestimate baseline values and underestimate change66.  Sheldon et al31 suggest that the correlation 
between RMDQ and VAS ranged from 0.657 and  0.703, and the VAS and PGART from 0.677 and 0.738, suggesting that results 
are similar enough that assessments may be simplified (eliminate one of these studies). Because the PIQ-6 also highly correlates 
with VAS, it was selected in place of the PGART. Similar correlation results have been reported by Kovacs et al at days 15 and 60 
of follow up, but not on initial (day 1)52 making long term follow up important. The PIQ-6/R satisfies this time course as it is 
designed for a 4 week follow up. Reasons for including a measure of quality of life (vs pain only) is that measuring the quality of 
life helps determine the clinical significance of statistical findings39. 
 
Patient Selection: It has been noted that the natural course of acute low back pain is such that rapid improvement of pain, 
disability, and return to work is experienced in the majority of patients by 4 weeks56. Further improvement is then noted up to 3 
months55,56. Of the patients who go on to develop chronic low back pain, 90% endorse stable pain and disability55. Kovacs et al 
note that the extent to which disability can be attributed to pain itself (vs psychosocial and cognitive measures) is highest in the 
acute setting (pain <14 days)53. Disability from chronic low back pain (pain >12 weeks in duration33) is also influenced by multiple 
factors to include both pain itself and psychosocial facotrs42.  Despite this finding, attempts to address the psychosocial aspects 
with antidepressants have inconsistently shown true benefit58,60.   Even though chronic low back pain is a multidimensional 
problem, authors such as Kovacs et al agree that the enduring presence of pain can predict disability, and disability in turn may 
predict quality of life. Treatment plans for patients with chronic low back pain encompass a variety of treatments from 
advice/continued activity to pain medications to use of complementary and alternative medicine43-46,49,54. Yet despite this 
multifaceted approach, a substantial number patients continue to experience pain and disability, albeit at a stable level55,56. 
Because of this stability, patients with chronic low back pain would be ideal study population to assess the impact of MSM on 
low back pain.  
 
MSM has not been well studied in low back pain. Tant et al report that it may be helpful in the treatment of chronic low back 
pain57 when coupled with glucosamine complex. However, their study used a small number of patients and did not include a 
true placebo control for glucosamine/MSM. Further information on MSM and chronic low back pain is otherwise lacking.  
 
Adverse Side Effects:  As noted above, Kim et al13. reported adverse side effects of bloating, constipation, indigestion, fatigue, 
decreased concentration, insomnia and headache, though these symptoms were not any more prevalent in the group taking 
MSM than the placebo group.  
 
Proposal of Materials and Methods:  Selection of proper follow up time has been based on studies of MSM in osteoarthritis. 
Follow up time ranges from 213 to 12 weeks12. In the study by Kim et al13, efficacy was not noted until 4 weeks into the study. This 
improvement was even more notable at 8 and 12 weeks than at 4 suggesting that improvement in symptoms may require longer 
exposure MSM. For this reason, the impact MSM on low back pain, function and quality of life should be carried out to at least 12 
weeks.  
 
The use of 4 week intervals for reassessment mirrors the protocol by Kim et al. This is convenient considering the PIQ-6/R was 
designed for a 1(acute) or 4 week (chronic) follow up. 
 
Inclusion and Exclusion Criteria for this study will be similar to the common criteria from various studies on Low Back Pain42-
44,52,55, 58, 61.  
Studies of MSM and osteoarthritis have recommended MSM dosing ranging from 500mg TID to 3 g BID12,13. Doses of 6 g daily 
are considered safe13,24. As noted above, studies in rats found that doses 5-7 times the maximum recommended daily amount 
may be given without any appreciable toxicity15,68. Human studies using >6gm/day have not been performed. MSM will be given 
in the dose of 1500mg x2 Tabs, BID. Standard of care naproxen is typically defined as a dose of 225-550 mgs twice a day although 
it may vary depending on the provider.

We will recruit male and female NELLIS AFB DoD beneficiaries between the ages of 18-65 years old with symptoms of lower back 
pain from any of the clinics at Nellis Air Force Base.  Patients taking Muscle relaxers of any type, Non-steroidal anti-inflammatory 
agents (NSAIDs), Tramadol, Gabapentin, Pregabalin, agree to wash out for two weeks prior to entering the study. 
Randomization will be performed by the research coordinator. Both Investigators and subjects will be blinded to study 
assignments. 
 
Screening Visit: 
• 
Obtain signed Informed Consent Document and HIPAA Authorization. 
• 
Review inclusion/exclusion criteria. 
• 
Record: name, race ethnicity, race, date of birth, age, sex, height (in inches), weight (in pounds), blood pressure, email 
address, phone number, history of lower back surgeries, medical history, concomitant medications, and record the

DIRECTIONS FOR TAKING MEASUREMENTS: 
Directions for weighing subjects:  Have subject remove his/her shoes and empty pockets of any items prior to stepping on the 
scale.  Weight should be recorded to the nearest ½ pound (for example 150.5#). 
 
Directions for taking height:  Have subjects remove their shoes before taking their height.  Height should be recorded to the 
nearest 1/2 inch (for example 60.5”). 
 
Directions for taking blood pressure: Have subjects sit for 5 minutes before taking blood pressure. 
 
VISIT WINDOWS: Visits will have a 1 week visit window. If a subject fails to come in within this visit window, they will be instructed to 
bring in any unused study pills and removed from the study. 
 
ADHERENCE TO STUDY ASSIGNMENTS: Adherence to study medication will be assessed via review of the “Study Medication 
Diary”. Compliance will be recorded both in paper format and in the electronic data collection tool. If a subject misplaces their 
Study Medication Diary, they will be asked to reproduce it from memory to the best of their ability. Subjects will be instructed to 
bring back all of the bottles regardless of whether there are empty or contain missed doses. 
 
If a subject misses a dose, regardless of the amount, they will be encouraged to document this in their study diary and resume 
taking their pills. All subjects will remain in the study and continue with all the study related visits.

Non-Exempt Human Research Study 
 
If a subject misplaces or loses their study medication, they will be instructed to return to the research department and will be 
given a new bottle of their assigned study medication.  Since the research coordinator is not blinded, they will be able to give 
the medication that the subject was assigned. 
 
If a subject forgets to bring their study medication in for their visit, they will be instructed to bring it in at their earliest 
convenience. 
 
WITHDRAWAL PROCEDURES: If at any time during the study, the subject decides to withdraw consent or if the subject is 
withdrawn from the study by the investigator, they will be referred to their Primary Care Manager (PCM) to continue with 
standard of care treatment. 
 
PREGNANCY: Subjects must agree to take precautions to prevent pregnancy during the course of this study due to the possible 
effect MSM may cause an unborn child.  The only completely reliable methods of birth control are total abstinence or surgical 
removal of the uterus.  Other methods, such as the use of condoms, a diaphragm or cervical cap, birth control pills, IUD, or sperm 
killing products are not totally effective in preventing pregnancy.  In addition, women who are breastfeeding may not participate in 
this study. 
 
If a subject unintentionally becomes pregnant, they will be instructed to cease taking their study pills, return their pill bottle and will 
be removed from the study.  
 
DISPOSAL OF STUDY RELATED PILLS:  Subjects will return any remaining study-related pills directly to the Research Coordinator 
or Principal Investigator. The Research Coordinator or Principal Investigator will be responsible for disposing of the study-
related pills. The preferred method of disposal is to have the Pharmacy dispose of them. If the Pharmacy is unable to dispose of 
them, they will provide directions on safe disposal for the Research Coordinator or Principal Investigator to follow. 
 
OTHER: Subjects will take their study pills daily and will be permitted to have the usual medical care for other co-morbid and 
acute conditions if applicable.  Analysis described above using intention-to-treat principles for any missing data will be used (we 
will use the carry-forward method to impute missing data). 
 
The placebo will be a capsule filled with rice flour, which does not increase the risks to subjects. 
 
This study involves the use of an investigational product (IP) called Methylsulfonylmethane (MSM).  This means that the product 
has not been approved by the Food & Drug Administration (FDA) for treating lower back pain.   It is being given in a dose that does 
not increase the risk to the research subjects.  There are no known risks associated with MSM as it is a compound granted GRAS 
(Generally Recognized As Safe) status by the United States Food and Drug Administration (more information can be found at 
http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=582.20). The Sponsor-Investigator will report 
unexpected SAEs associated with the use of the drug to the FDA as specificed at 21 CFR 312.32(c). 
 
3.6.1. Interventions, Observations, or Data Sought:  
We will assess the effect of 6000 mgs of MSM plus standard of care naproxen taken for 12 weeks plus one follow up visit on 
RMDQ, PIQ-6, pain level, comprehensive metabolic panel (CMP) and complete blood count (CBC) will be assessed at 4 week 
intervals. 
 
3.6.2. Data Collection and Processing: 
Data will be collected and recorded in a spreadsheet. At the conclusion of the study, all personally identifying information will be 
removed prior to analysis based on AFI 33-332, “The Air Force Privacy and Civil Liberties Program” and the “National Institute of 
Standards and Technology Special Publication (NIST SP 800-88) for the approved methods to destroy PII”. 
 
3.6.3. Setting: Mike O’Callaghan Military Medical Center at Nellis Air Force Base.

3.6.8. Instrumentation: N/A 
 
4.0.  Human Subject Protection: 
 
4.1. Recruitment:  
All potentially eligible patients will be offered an opportunity to participate. Primary Care Managers (PCMs) who are not part of 
the research team will be informed about the study and provided information on the inclusion/exclusion criteria. PCM referrals 
and posted advertisements will be utilized for recruiting subjects to the study. Some patients may be patients of the PI or AI, 
however, they will have the study staff recruit their patients to prevent any misconception of coercion or undue influence. If a 
potential subject is identified by the treating PCM and is interested in obtaining more information about the study, the patient 
will either be provided a contact number to the Research Staff, the Research Staff will be given the potential subject’s contact 
information by the PCM with the patient’s oral or written authorization, or the PCM will come and get the Research Staff to 
speak with the patient directly.  
 
4.2. Consent Processes:  
The PI, AI, or Research Coordinators will obtain Informed Consent on this study.  Informed consent and HIPAA Authorization will 
be sought in advance from each prospective subject.  Informed consent will be appropriately documented.  [32 CFR 219.117]  
After discussion with one of the investigators, the subject will be given the opportunity to consent.  The investigator will provide 
a written copy of the consent form and allow the subject to read it, review it with the subject, and answer questions.  The 
subject may decline to consent, and no pressure will be applied.  If the subject consents to be enrolled in the study, the proper 
signatures will be obtained, and a copy given to the subject. 
 
4.3 Participation Compensation:  Subjects will not be paid for participation in this study. 
 
4.4. Assent Process: N/A 
 
4.5. Benefits:  The benefits to the subjects may include a decrease in lower back pain and increase in function. 
 
4.6. Risks:  Risks to the subject are minimal.  
 
Since the interaction between MSM and the medications in the exclusion list that require a washout period (Muscle relaxers of 
any type, Non-steroidal anti-inflammatory agents (NSAIDs), Tramadol, Gabapentin, Pregabalin, Glucosamine, Narcotic pain 
medications) have not been studied, patients will be asked not to resume taking these medications while participating in this 
study.
