Soft-Tissue Injury Treatment for Los Angeles Baseball Players

Obliques, hamstrings, lats, forearms — the strains that sideline hitters and pitchers rarely start where they hurt. At The Fascia Institute and Treatment Center of LA, we map the fascia along the whole kinetic chain, then treat the actual driver so you get back on the field and stay there.

Why baseball breaks down soft tissue

The strain is rarely where the problem lives

Baseball is a rotational, one-sided sport played at high velocity, and the tissue that pays the price is soft: the abdominal obliques that fire on every swing and throw, the hamstrings that load and explode out of the box and around the bases, the lat and forearm flexors that decelerate a 90-plus-mph arm. These aren’t freak accidents. They’re the predictable cost of asking one side of the body to generate and absorb enormous force, thousands of times a season.

Oblique strains are now among the top time-loss injuries in professional baseball, and pitchers miss roughly four weeks on average once one occurs.1,2 Hamstring strains are the single most common injury across Major and Minor League Baseball — more than 2,600 in a recent six-year window — and they come back: recurrence rates run north of 16%.3 That recurrence number is the tell. When an injury keeps returning to the same spot, the tissue that was actually driving it was never addressed.

Sports medicine has caught up to what throwers have always felt: you can’t evaluate the arm in isolation. The shoulder and elbow sit at the end of a kinetic chain that starts in the legs and core, and researchers now argue there is far more to assess in a pitcher than the arm itself.4,5 That is exactly where fascia — the continuous connective-tissue web that links every muscle group — becomes the missing piece.

The baseball injuries we treat

Where players actually get hurt

Oblique / core strains
The rotational-power injury. Common in both hitters and pitchers, tied to throwing and swing workload, and slow to return because the whole trunk loads on every rep.1,2
Hamstring strains
The base-running and sprinting injury, and the most frequent in the sport — with a stubborn recurrence rate. We treat both the fresh strain and the chronic hamstring that never fully healed.3
Lat & shoulder soft tissue
Shoulder-region pathology accounts for a large share of baseball injuries, with pitchers heavily over-represented. Fascial restriction around the lat and posterior shoulder often limits the arm before the tissue tears.5
Forearm & elbow flexors
The deceleration injury. Flexor-pronator and forearm strains that show up as “tightness” or “dead arm” long before they become a structural problem — and are increasingly common even at the high-school level.6
“Everywhere and nowhere”
Recurring strains, nagging tightness, and pain that scans call normal. Often a fascial-adhesion problem along the chain rather than a single torn muscle — which is why it never resolves with rest alone.
How we treat it

Map the chain, then release the driver

Our founder, Dr. Jacques Courseault, MD, is a sports-medicine physician who developed the tools this clinic is built on. Instead of chasing the sorest spot, we work the whole system.

1 · Fascial Mapping®
A detailed ultrasound scan of the fascia along the kinetic chain to find the adhesions and restrictions that are loading your obliques, hamstrings, or arm. See Fascial Mapping.
2 · Hydrofascia Release™
Ultrasound-guided release of the restricted fascial plane — not a cortisone shot. The same approach behind Dr. Courseault’s published hamstring hydrodissection procedure.7,8 Learn more: Hydrofascia Release.
3 · Regenerative options
For ligament, tendon, and instability problems: Dextrose Prolotherapy and ProloBoost Dual PRP. Plus Shockwave and HUMAN TECAR for tissue recovery.
4 · Return & prevent
Structured return-to-play and re-injury reduction through The Fascia Performance Program, with genomic recovery insight from FIT GPS.
From our clinic to the big leagues

Care that travels with the player

We were proud to see one of the athletes we’ve worked with reach the next level when Kendall Hagedorn signed with the Milwaukee Brewers. What made his path notable for us is that he received fascia-focused care on both coasts — a reminder that a serious baseball career doesn’t stay in one city.

That’s the advantage of The Fascia Institute network. Our flagship in New Orleans and our Beverly Hills clinic run the same protocols, so a player can start treatment in one place and continue seamlessly in the other. Whether you’re training in Los Angeles, headed to a program out of state, or moving up through an organization, the plan follows you.

Common questions

Baseball soft-tissue injuries, answered

My hamstring keeps re-tearing every season. Can that be fixed?

Recurrent hamstring strains are extremely common in baseball — recurrence exceeds 16% in the pros.3 Repeated re-injury usually means a fascial adhesion or unaddressed driver up the chain is never healing fully. We map it under ultrasound and treat the restriction directly rather than just resting and re-loading.

Do you treat pitchers as well as position players?

Yes. Obliques, lats, forearm flexors, and shoulder-region soft tissue are all part of the throwing chain. Modern sports medicine stresses that a pitcher is far more than the arm,4,5 and our whole-chain fascial approach is built for exactly that.

Is Hydrofascia Release a cortisone or PRP shot?

No. Hydrofascia Release is an ultrasound-guided release of a restricted fascial plane. PRP and prolotherapy are separate regenerative options we offer when a ligament or tendon needs it — we choose based on what the map shows.

I’m a high-school or college player moving out of state. Can care continue?

Yes — that’s a real strength of our two-location network. Our Beverly Hills and New Orleans clinics use the same protocols, so your plan continues across the country. Telehealth follow-ups are available for California-based patients between hands-on visits.

I’ve been told I’m “just flexible.” Could that matter for my injuries?

It can. Hypermobile athletes tend to accumulate more soft-tissue strains and slower recoveries. Our hypermobility and EDS evaluation, and the network’s dedicated hypermobility clinic, address that directly.
