Decompressive laminectomy (DL), the most common spinal surgery in older adults, is performed to alleviate lumbar spinal stenosis (LSS) and reduce associated pain, paresthesias, and/or weakness when walking (i.e., intermittent neurogenic claudication - INC). The PI's recent prospective cohort study of 193 older veterans followed for 12 months following DL revealed that over 50% of participants did not experience significant functional improvement. Similar rates of failed surgery have been reported in non-veteran populations. Since the vast majority of DLs are performed electively, non-surgical treatment is recommended as an initial step. Two clinical trials have demonstrated modest efficacy of manual therapy and exercise (MTE) for people with INC that was sustained in one trial, but not in the other. Recent clinical practice guidelines recommend adding acupuncture as a non-surgical pain management strategy and highlight the need for high quality evidence to support this recommendation. The investigators' clinical experience and preliminary research data regarding the efficacy of electroacupuncture (specifically, intramuscular electroacupuncture \[IMEA\]) in these patients are promising. Ultimately, the study team wishes to conduct a randomized controlled clinical trial to optimize and sustain the efficacy of MTE by potentially a) increasing the robustness of the initial response via addition of IMEA and b) its durability via boosters. This two-site feasibility study will be conducted at Boston Medical Center and the Orlando VA Medical Center, chosen because of their sociodemographic diversity and prevalence of patients with multiple comorbidities, characteristics that will ultimately facilitate broad generalizability of study findings. The study team will evaluate the feasibility of recruiting, randomizing and retaining participants; fidelity of intervention delivery; participant adherence to prescribed interventions; and the accuracy and completeness of data collection procedures. Sixty participants (30 per site) with imaging-identified LSS and INC who have not had lumbar surgery, will be randomized to receive 1) MTE for 3 months (10 sessions over 12 weeks) followed by a 6-months observation period; 2) MTE for 3 months followed by monthly MTE booster sessions for 6-months; OR 3) MTE + IMEA for 3 months followed by monthly MTE + IMEA for 6-months. The primary outcome (Brigham Spinal Stenosis questionnaire) for the future efficacy trial will be measured at baseline, 3 months (primary endpoint), 6 and 9 months. The study also will measure community mobility (life space), emotional functioning (PHQ8 and GAD7), pain medications, and other key parameters relevant to older adults with LSS and INC (e.g., smoking, BMI, medical comorbidity). Fidelity will be optimized by delivering standardized provider training, conducting regular review of participant provider intervention sessions and documentation, and monthly all-site huddles. The study also will monitor participant attendance and home exercise compliance. If the study demonstrates feasibility (primary outcome for this study) of the proposed methods, the study team will be positioned to test a new model of care for patients with LSS and INC designed to optimize their function and quality of life and save substantial morbidity and healthcare resources.
