    1. 1. Deborah Bade Horn DO MPH FASBP ASBP Board of Trustees, Vice-President Medical Director, Center for Obesity Medicine & Metabolic Performance Asst. Professor, University of Texas Medical School Physical Activity Prescription: Assessment & treatment to improve functional & metabolic capacity. American Society of Bariatric Physicians®
    2. 2. Objectives “Results Typical” Weight Maintenance & Metabolic Health © Horn 2012
    3. 3. Road Map  “Results Typical”: Review the Guidelines for Physical Activity Translate this into success for the patient with obesity  Case Based Application: Discuss the provider approach & areas for improved treatment Creating an individualized PA prescription Reducing the risks involved with PA  Interactive Delegate Experience
    4. 4. 5 Most Common Recommendations for PA A. Wait until you are at your goal weight. Right now just focus on your diet B. Walk 30 minutes per day 5 days per week C. Take the stairs and Park your car farther away D. Join a Gym E. No Pain, No Gain What’s your PA Rx for a patient with obesity?
    5. 5. How Much Physical Activity is Enough? General Health Benefit  Moderate aerobic exercise 150min/wk (About 30 minutes 5x/wk) + Strength Training Prevent Weight Gain & Active Weight Loss  150-250 minutes per week  150-300 minutes per week Prevention of Wt Regain  200-300 minutes per week  300-420 minutes per week Donnelly J. Am College Sports Med. 2009. US Health and Human Services. 2008.

    40. 40. What did you choose? Oct 14, 2012 ADL’s with assistance RPE 2-8 10/10 PT-2 X X X X Strength and H2O H2O - 3 Needs Stress Test/Phys Therapy Eval for falls eval prior to initiation. When cleared:170min/wk. 2 weeks Personal Trainer 2/10 X PCPA Mod 1-2 Leg Ext, Crunch, Deborah Bade Horn DO MPH PCPA-3 1 28 13 NA NA © Horn 2012
    41. 41. Exercise Prescription  Falls precautions  Initially: – Pool work: anti-gravity – Personal training – PCPA  No DM Med changes, but begin monitoring  Eventually – Physical therapy – Review presurgical approach  Begin Pain journal to facilitate medication adjustment 1st Goal: >170 min at RPE ≥ 4, minimal joint pain Optimal Goal: >250 min, RPE ≥ 5, Doubles Tennis?
    42. 42. Progress: Ortho/ Pain Meds  During the course of obesity treatment: – Bilateral Total Knee Replacements – 1 TKR revision  Pain med adjustments – Pain Mgmt consult – Weaned off controlled substances – Ultimately, Ibuprofen occasionally
    43. 43. Progress – Weight & PA Maintenance  Lost and maintained 54.5kg (120 lbs). weight loss throughout 3 surgeries over 18 months.  Physical Activity?
    44. 44. Long Term Planning What would you do?
    45. 45. Long Term Planning  After bilateral TKR and 1 revision: – Off walker after extensive pre and post surgery PA – Minimal intermittent pain
    46. 46. Putting it into Long Term Practice Step 1: Complete your PA Top 10 for EVERY patient. Step 2: Develop an Exercise prescription SPECIFIC to individual needs. Step 3: Monitor progress & update Ex Rx every visit Step 4: Revise goals at least every 3 months. Step 5: Be Creative & think outside the treadmill! © Horn 2012
