indicate?,Surgery is generally the gold standard.(Negrini et al 2010;Zaina et al 2012)Only a few studies have compared surgical vs non-surgical treatment.(Negrini et al 2010)Evidence regarding conservative management is limited and vague.(Atlas and Delitto 2006;Birkmeyer et al 2002;Goren et al 2009;Tomkins 2010 cited in Zaina et al 2012)However.,What does the literature indicate?,Research non-specific/no current standard for conservative care.Therefore do positive results truly support surgery?(Backstrom et al 2011)Long term effectiveness of surgery has been questioned.(Backstrom et al 2011;Fritz et al 1998)Patient selection for surgery is ill-defined.(Backstrom et al 2011)High risk and costly.(Fritz et al 1998),What does the literature indicate?,Conservative/non-invasive=recommended first line intervention.(Negrini et al 2010;Fritz et al 1998)The natural history of LSS is not necessarily a progressive decline.(Fritz et al 1998)Patients with mild to moderate symptoms of lumbar stenosis have satisfactory outcomes following conservative management(Goren et al 2009),Proposed Conservative Adjuncts,Patient Education and Manual Therapy,Inform patientRationale forSelf management strategies(Backstrom et al 2011;Johnson et al 1991;Rademeyer 2003;Voet et al 2005)Manual TherapyUse as a component of LSS is associated with improvements in pain and disability(Reiman et al 2009;Zaina et al 2012;Goren et al 2009)Techniques used are varied/applied to different regions(Backstrom et al 2011)Choice of procedure less important than the introduction of movement through manual therapy.(Backstrom et al 2011),Exercise Prescription,Aerobic Training and Progressive strengthening:(supervised circuit/Spinal class/Home exercises)(Backstrom et al 2011;Goren et al 2009)Core Stability Exercise:Done with a flexion bias emphasizing pelvic control e.g.shoulder bridge(Backstrom et al 2011;Fritz et al 1998)Flexibility:Overall stiffness=common LSS presentation.(Fritz et al 1998;Whitman et al 2003,2006;Creighton et al 2006;Murphy et al 2006 cited in Backstrom et al 2011;Zaina et al 2012).Limited evidence directing exercise dosage in patients with LSS.DO WE UNDERTREAT?(Backstrom et al 2011),Outcome Measures,Multi-dimensionalObjective markers Patient Goals/FunctionRoland Morris/ODI/EQ5DVASTimed walk(15 minutes)Sit to stand,Considerations and Onward Referral,Relies on correct differential diagnosisDifficult due to similar coexisting symptoms(Fritz et al 1998)NUH 4-6 sessions.If no change in symptomology the?onward referral.In reality there are no standard/set criteria for timeframes of conservative Mx,Summary,Patients with mild to moderate symptoms of lumbar stenosis may benefit from conservative management(Goren et al 2009)However:Few existing RCTs(4/178)that specifically examine and report on patient with LSS receiving conservative treatment.(Agency for Healthcare Research and Quality 2001).Studies do not evaluate applications alone.(Goran et al 2009)Research fails to evaluate long term effectiveness of conservative management.(Agency for Healthcare Research and Quality 2001).Lack of comparable patient groups and pre-treatment data for both surgical and conservatively managed patient groups(Agency for Healthcare Research and Quality 2001).True comparisons are difficult as many patient treated conservatively end up having surgery.(Agency for Healthcare Research and Quality 2001).,Summary,However does this lack of evidence prove that these treatment are not effective?(Rockville 2001)Need to consider each individual patient and their symptomology when deciding conservative vs surgical.Need to establish set outcome measures for patient with LSS.,Appendix,Indications,Lower limb pain Neurological symptoms exacerbated by walkingNeurogenic claudicationReduced walking capacities,Injection,Epidural steroid injections used increasingly to relieve symptoms.(Delport et al 2004;Campbell et al 2007 cited in Backstrom et al 2011)Low level evidence studies show some benefit in patients with spinal stenosis.One RCT indicates temporary relief for one month.Conclusions beyond three months cannot be made.(Agency for Healthcare Research and Quality 2001).Systematic review concluded more strenuous studies need to be performed.(Nelemans et al 2005;Buenaventura et al 2009 cited in Backstrom et al 2011).Often used in combination with physiotherapy.,Neurodynamics,Consider that pathoneurodynamics may be contributing to symptomology.Neurodynamic testing and reproduction of symptoms using differentiation may indicate neurodynamics treatment.Nerve glidingTreatment of mechanical interface:Trigger point/acupunctureTaping to offload:Inhibitory across muscle fibres.Neural offloading:reduces nociceptor impulses,References,Atlas SJ,Delitto A:Spinal stenosis:surgical versus nonsurgical treatment.Clin Orthop Rel Res
