This one is hard to see. The NIH Early Independence Award, one of the most competitive grants in the country for young scientists, will not go forward in FY2026. NIH says this is due to “administrative changes to funding opportunity processing and delays in approvals.”

A bunch of Ups and Downs for my Junior Season. Got hurt in our first game. Ended up missing 4-5 games and was in and out of the lineup for the first half of the year. Was able to full recover and bounce back by the end of the year. Looking forward to a great summer season with @elite_national2 H: 15 (9 1B, 4 2B, 1 3B, 1 HR) BB: 13 HBP: 2 0 Errors @jgrosse32 @ewall_0405 @UDCardinalPride @NextLVLProspect

Rehabilitation should be periodized. Most of the time, it isn't. Periodization means the systematic manipulation of training variables to build specific qualities in a planned sequence. In late-stage rehab, a practical force-to-performance sequence looks like this:

The most dangerous words in sports rehab: "Their symmetry looks good." Here's why: When an athlete deconditions post-injury, BOTH limbs lose capacity. So when you calculate a limb symmetry index comparing involved to uninvolved,

We measure quad strength to the decimal. We should be measuring fear with the same rigor. Psychological readiness is one of the most underused domains in return-to-sport assessment and research suggests it may be one of the most predictive.

Acceptable symmetry scores can hide dangerous movement strategies. Here's what to watch for WHILE your athlete is completing a hop battery or change-of-direction test:

🔑 Key rules: → Require controlled landings — not "saved" landings → Use consistent rest periods → Observe movement QUALITY, not just distance or time → Combine with strength data and self-report; never interpret alone

🦵 Crossover Hop for Distance: 3 hops while alternately crossing a center line. Makes frontal and transverse plane control visible. 🦵 6-Meter Timed Hop: Hop through a 6-meter course as fast as possible. LSI = uninvolved time ÷ involved time × 100.

Quick clinical guide: the 4 hop tests you should be using and why each one matters. Hop tests are a window into function. Don't mistake them for the full picture.

I use one clear decision node to make return-to-sport calls: hit all criteria, or don’t clear. It makes decisions simpler and documentation defensible. Learn how Athlete Motion Institute’s system reduces uncertainty: wix.to/df8tuQp #SportsPT

@KalkhovenJudd @SportsMedicineJ Judd, I look forward to reading this.

I’m delighted to share that my new article titled “Developing a Fundamental Theoretical Definition for Athletic Injury: Metaphysics, Logic, and Mathematics” has just been published in @SportsMedicineJ There are many motivations behind this article, and it is difficult to list them all. However, I will briefly highlight the main ones. Progress in modelling and predicting athletic injury has been limited, and a major reason for this, in my view, is a lack of conceptual and logical clarity surrounding what an injury actually is. This may seem strange, but I have faced an extraordinary amount of resistance on this topic across numerous debates and review processes. With this article, I want to emphasise that the approach does not rely on an appeal to authority or a purely stipulative definition, but instead focuses on the underlying logical structure required for a concept to function as a coherent and scientifically useful explanandum. In this context, there is an underlying logical structure to how injuries can be defined, modelled, and ultimately predicted, including time-loss injury, and if that structure is not respected, we will likely never see meaningful progress in this area. I would also like to highlight that this article is not just about developing a definition, but examines the role of philosophy of science, language, logic, and mathematics in establishing coherent and falsifiable foundations for scientific research. I see similar debates around definitions and semantics occurring in other fields, and I hope that the methods explored throughout this article may also be utilised in those areas. I am considering writing a similar article for the field of pain science, which also has major issues with definition and falsifiability. I would like to thank @francoimpell , @edwardswb, and Mark Watsford for their mentorship and support. I would also like to thank @DNorrisSC and @scotmorrsn for deep debates and valuable discussions on this topic that contributed enormously to this article. I also thank the reviewers for the considerable time and effort they put into reviewing the manuscript. I hope that you enjoy reading it. It is a precursor to another article on predicting athletic injuries that will come out in the next few weeks. link.springer.com/article/10.100…

I built 131 Claude skills for outbound, content, LinkedIn, SEO, and growth—inside one system. 131 skills. 11 domains. One /bootstrap. And the result? Prospects keep saying: "Your outreach actually sounds like you." That’s not better prompting. That’s system design. ▶️ The foundation (set once) → /bootstrap trains Claude on your brand, voice, and ICP → ICP doc is loaded once—used everywhere automatically → Brand + voice layer ensures every output sounds like you, not a template Most teams skip this. Then wonder why everything feels generic. ▶️ The skill layer → Outbound + email for personalized sequences at scale → LinkedIn, X, YouTube across every format → Content + copy that matches your actual voice → Analytics + research for real signal detection → Strategy for ICP, messaging, and positioning (47 growth + product skills alone) ▶️ The execution layer → Plain-language inputs → auto skill activation → Cross-referencing across brand, voice, and ICP → Built-in grading: If it sounds generic → it’s not specific enough yet Rule: If it could describe another company, it’s not done. ▶️ Repurpose One proven outbound system → Turned into content, SEO, positioning, paid Not copy-paste. Cross-referenced intelligence. ▶️ Maintain → /bootstrap refresh updates everything instantly → Monthly voice updates → Quarterly domain audits The system compounds over time. ▶️ Delivery Runs on Claude Code, Claude Cowork, or any agent-based setup. Flow: Bootstrap → Detect → Activate → Cross-reference → Draft → Grade → Repurpose → Refresh Your skill library isn’t a tool. It’s your GTM brain. Reply “CLAUDE” and I’ll send the full breakdown 👇

Let's settle this. I've asked this question in every continuing education room I've been in — and the answers are always split. 🗳️ POLL: When do you consider an athlete "officially" cleared for return to sport? Some answers lead to better outcomes than others.

Another huge win today. Went 1/2 with an Oppo 2B and 2 BB. Looking to keep it up the rest of the season. @elite_national2 @jgrosse32 @UDCardinalPride @NextLVLProspect

@ShurillaGorilla @APTA_official Thanks Jeff

@DaveLogPT @APTA_official Congrats!

I was recently elected as a Catherine Worthingham Fellow of the American Physical Therapy Association @APTA_official. I am incredibly humbled and honored. The mentorship and friendships along the way made this possible. My goal is to have an impact, in the clinic or classroom.

The Bern Consensus and the Panther Symposium agree on one thing: return to sport is NOT a moment. It's a process. Here's the clinical framework every sports rehab clinician should know. This is the foundation of everything we teach.
