Hot Topics & Research

January 2021:


We've got new tech - a BEMER - and we're excited to share it with our patients...


Pulsed ElectroMagnetic Field (PEMF) Therapy is not new. (In fact, professional golfers, cyclists, American football players, triathletes and those who follow horse racing have known about it for years.) But research into the exact specifications/waveforms/ultra-low intensity most beneficial has grown recently. PEMF specifically and assertively enhances blood flow in the microvessels – which comprise 75% of the body’s vascular/lymphatic system. Microvessels are challenging to target after injury/surgery/prolonged persistent pain conditions. PEMF is known amongst high performance professional athletes and orthopedic surgeons as a key tool in recovery, healing and pain reduction. The company BEMER is the PEMF industry gold standard – it’s German engineered, Swiss made, and recently partnered with NASA to counter the effects of muscle and bone loss in astronauts.


Benefits of BEMER:

  • nutrient & oxygen delivery
  • local blood flow
  • waste removal
  • muscle conditioning
  • performance
  • endurance & energy
  • vitality & well being
  • stress reduction & relaxation
  • sleep management


Pulsed Electro Magnetic Field (PEMF) studies on PubMed -


Arthritis: knee OA syst lit review/meta analysis knee OA spine DDD

Dear friends –


On Feb 17, 2020 a long-awaited trip to Japan, for the purpose of running my sixth and final World Marathon Major (an endeavor that began in 2014) -the Tokyo marathon, was cancelled. Little did the running community, let alone North Americans at large, realize the global impact that would be created mere days/weeks later by a tiny new microorganism.


Resources for sound and accurate information on COVID-19 "coronavirus": WI Health Department, Centers for Disease Control, and World Health Organization


Hand Washing, staying 10 feet apart from other individuals, & 'Physical Distancing' away from groups of people are top means to preventing infection and spread of COVID-19 “coronavirus”. To reinforce the rationale for how crucial it is to isolate in order to minimize spread and 'surge' in need for ICU beds/oxygen machines this 30min JAMA (Journal of the American Medical Association) video is worth every minute of viewing time. 


Ideas to counter boredom, anxiety, and loneliness during this challenging time:

  • Spend a minimum of 40min walking/hiking/jogging outside daily
  • FaceTime/Skype/call a friend or loved one and talk, talk, talk
  • Do your P.T. Home Exercise Program (HEP) then call the office/email to let me know how it went!
  • Purge or organize closets/drawers
  • Set up a white board schedule for yourself, your family - sample below
  • Current class participants: Join CoreActive for a virtual 1-on-1 class in Essentrics or Ms Fit Therapy!
  • Clean/sweep out the garage
  • Work on a puzzle
  • Dig out heirloom family recipes
  • Hang a bird feeder
  • Play a board game
  • Host a virtual 'hang out' with friends and loved ones
  • Blow bubbles
  • Support a local restaurant and order take out/delivery: Delaney's, L'Etoile, Bloom Bake Shop, Salvatore's Tomato Pies
  • Support a smal business in another industry: order a voucher for a family photo session, buy a gift card for future spa services (massage, facial, or acupuncture), or buy a clothing item/accessory for your first day back in the office/meeting a friend IN PERSON for coffee!
  • Start an online learning/continuing education opportunity
  • Need a job? Take action by helping make Personal Protective Equipment (PPE) to support doctors and nurses in our hospitals and urgent care clinics
  • Learn a new skill (coding, playing the guitar, etc)
  • Read a novel or bio (Chanel Cleeton’s When We Left Cuba and Next Year In Havana or Heather Morris’ The Tatooist of Aushwitz or David GogginsCan't Hurt Me all excellent)  
  • Check out mental health focused resource: link on Emotional Intelligence
  • Get into meditation; check out the app: Calm


In times of uncertainty I find comfort in leaning on the knowledge of experts and talking with trusted friends about our shared journey. I hope and pray for strength for CoreActive and fellow small businesses. As an endurance athlete I find marathon and ultra event metaphors crossing my mind daily. As a parent I think this experience is shaping young people into a more appreciative and global minded 'Greatest Generation'. I look forward to again seeing patients and clients in person. Know that if you have Qs I am available by virtual appt from now through at least late April 2020.

What we read, watched, and listened to in 2019...


On Nutrition:

The Game Changers narrated by retired English MMA athlete James Wilks; vegan athletes achieving greatness in endurance and power endeavors; produced by Jackie Chan and Arnold Swarzenegger. Featured team pursuit cylcing athlete (now retired) Dotsie Bausch's website includes excellent plant based recipes.


On Athletic Motivation:

Can't Hurt Me "The 40% rule" touted by Army Ranger and Navy Seal veteran and ultra-endurance athlete David Goggins.


On Inspiration:

Brave Like Gabe This organization champions the life & fierce determination of now deceased American distance runner Gabriele "Gabe" Grunewald.


On Evolving:

Calm app - 10min "Daily Calm" aligns with current "dosing" recommendations for a variety of beginner meditation goals. The focus on breathing enhances PMF (present moment focus) and most "Daily's" include a little something for everyone: quiet time, intention, soothing sounds, pardigms to ponder, and inspirational quotes. Give it a chance, dedicate, and be amazed at the inner power growth.

Power of Sportsmanship


The April 2018 Boston Marathon brought about some of the best stories in recent American running history. Ferocious wind and temps in the low 30s (F) created a shuffle amongst the leaders. Tenacious champ Des Linden prevailed as the first US woman to win since 1985. Linden's efforts/choices favoring teamwork and the incredible stories of fellow top female finishers provide a decade's worth of lessons all in one day, one race.

Spring/Summer 2014


A hot topic in Pain Research includes non-pharmacologic options for those affected by migraines, neck and back pain, and persistent pain conditions.  Well designed randomized controlled trials (RCT) and systematic literature reviews are indicating up to 40% reduced pain with a consistent daily breathing meditation practice.  20min per day is the key "therapeutic dose" cited most often.


Running Research is now focusing less on footstrike and more on what's happening "up the chain" at the gluteal muscles and the interplay between pelvis control and hip flexibility.  Research indicates a skilled and experienced Physical Therapist is a crucial running analysis resource. CoreActive Therapy is providing runners of all skill and experience levels with comprehensive neuromusculoskeletal examination and assessment for optimal performance, as well as prevention and treatment of common and complex conditions.


CoreActive's owner, J Klestinski, PT, MPT, OCS, WCS, CSCS, BCB-PMD, presented a literature review and case studies on Incontinence in Athletes at the Combined Sections Meeting of the American Physical Therapy Association on February 6, 2014 in Las Vegas, NV.  Geared towards practicing as well as student PTs interested in pelvic rehabilitation in the athlete, this evidenced based presentation was hosted by the Section on Women's Health and focused on pelvic floor issues affecting impact and endurance athletes.

Fall 2013 - CrossFit has exploded in popularity...but being an informed consumer is paramount to the health and success of the sport.  Benefits of movement variety through cross training, weight lifting, and mental toughness apply to athletic pursuits and life.  Yet, complications from CrossFit range from extreme pelvic floor pressures (read: bladder/bowel leakage) to non-reversible muscle damage and kidney failure.  Bottomline: Listen to your body!  Few research studies on CrossFit exist yet, however, case reports on serious risk factors are growing in number. 


Contrary to this video, it is NOT normal to leak "even a little" with jumping rope (aka "double unders") or with running, lifting, or playing sports in general.  Understand and educate others: pelvic physical therapy is highly effective and the first line of treatment for leakage.  Prevention through education and practice on properly engaging deep core muscle layers (see Ms Fit Therapy class) is key to ward off a major risk of CrossFit participation. 

Inspirational Achievements


National - Autism and running can be a great fit!  Giving hope to many parents, this New York prep athlete is aiming for a top Division I program to "run against the best in the country."   

International - All at once inspiring and heartwrenching, world-class runner Julius Achon's personal journey and his Children's Fund in northern Uganda are ones to watch.  


Spring 2013 - American Physical Therapy Association's public education arm, Move Forward PT, broadcasted an excellent resource by a fellow women's health PT on the role of PT during and after pregnancy.



CoreActive owner J. Klestinski was published in the May/August 2012 issue of the Journal of Women's Health Physical Therapy as co-author in a systematic literature review looking at the effects of specific exercise on pelvic girdle and low back pain during pregnancy.
