Send us a textWhat if everything we think we know about human walking is oversimplified?In this episode, we sit down with Dr. Steven Gard a biomedical engineer and leading gait researcher.  We unpack the real biomechanics behind prosthetic design. From artificial heart labs to O&P innovation, Dr. Gard shares surprising insights on:Why shock absorption and “energy return” don’t always behave the way prosthetic marketing suggestsHow soft tissue acts as a natural spring, changing everything about how force is transmitted through a limbThe ongoing debate between ischial containment, subischial, and elevated vacuum sockets — and why no design is one-size-fits-allWhere microprocessor knees and 3D printing fit into the future of mobilityThe missing link between engineering theory and clinical practiceWhether you’re a clinician, researcher, or just prosthetics-curious — this episode reframes gait in a way you’ve never heard before.Special thanks to Advanced 3D for sponsoring this episode.Support the show

Send us a textCredit card rewards expert Colin Stroud reveals how O&P practice owners can transform regular business expenses into valuable rewards through strategic credit card usage. He explains the mechanics behind credit card rewards systems and how business owners can maximize returns on spending they would do anyway.• Single practitioner O&P clinics typically spend $15,000-$20,000 monthly on components• Larger clinics can spend $100,000-$200,000 monthly, generating substantial reward potential• Credit cards offer both cash flow advantages and rewards generation simultaneously• Cash back options typically max out at 2-2.5% return on spending• Points-based flexible currencies can yield 5%+ returns when redeemed strategically for travel• Rewards are considered rebates rather than taxable income• Multi-owner practices can divide points proportionally among partners• LinkedIn content marketing has driven Colin's entire business growth without paid advertising• The "arbitrage opportunity" of points redemption delivers significantly higher value than cash backVisit Colin on LinkedIn (Colin Stroud - with one L) or at gosomewhereworld.com to access his free newsletter and guides on maximizing credit card rewards.Special thanks to Advanced 3D for sponsoring this episode.Support the show
