Re-cently, a new phenomena that I callthe “Sudden Runner’s Syndrome” hasappeared.

Assessment of Problem: History

The lower extremity is the areamost often injured in running,with the knee, Achilles tendon,tibia and foot being the most fre-quently affected structures. The po-diatrist is one of the most impor-tant consultants for the runner.

Besides the usual questionsthat you will be asking in yourhistory taking regarding timeand nature o f onse t , type o fpain and so on, you will need tospend considerable time review-ing your pa t i ent ’ s t r a in ingschedule (log) and secondarilytheir training and racing shoes.

Biomechanics is only part ofthe problem and will only offer aportion of the solution to mostrunning-related injuries. As wehave noted, most running injuriesare caused by overtraining and itis important to evaluate wherethe training error was made. Cor-recting the overtraining is notusually sufficient to treat many ofthe problems seen in cl inicalpractice. Shoe changes, lower ex-tremity strength improvement,c o r e b o d y s t r e n g t h ,a n d stretching to enhance flexi-bility need to be prescribed aswell as a revised training s c h e d -u l e . O r thotics of course do play

erable number of injuries, even whencarried out within the context of arun/walk program. This new athletedeserves respect and should be well-treated and encouraged to continuethe new found exercise regimen withappropriate modifications and treat-ment for the injuries.

Improper running shoes are an-other major factor in the develop-ment of running-related injuries.Contributing to overuse injuries isthe overused shoe. It is importantto examine all aspects of your pa-tient’s use of running shoes from fitto design to how long the shoeshave been worn to differences intraining and racing shoes.

When you treat experiencedrunners, they will rarely want tohear the advice “stop running”. Savethat for severe injuries. Keep inmind the concept of relative rest.Advise your runners to avoid run-ning to the point of pain during arun or what would create pain fol-lowing the run. Review their sched-ule and if possible, try to determinewhat, if any, running is possible thatwill not cause a rebound increase inpain. Prescribe alternative forms ofexercise that may be less stressfulsuch as cycling, pool running, swim-ming, or the elliptical trainer.

a role in the treatment and pre-vention of future running relatedinjuries, but the other parts of theequation must not be neglected.

Training Evaluation AndAssessment

Ask your patients to bring intheir running logs. These logsshould have daily and weeklymileage and brief notes on the run.Feelings of pain and discomfort areoften listed. You’ll be able to seewhen an injury began and whattraining preceded the injury. Lookfor sudden increases in mileage.Look for a large jump in the longrun. Usually in marathon training,the long run will only increase byone to two miles per week. An in-crease of three or four miles in thelong run and the absence of “easy”weeks, during which there is a de-crease in mileage are red flags.

Note the time of day and thetype of terrain your patient hasbeen running on. A change to run-ning on hills may aggravate plantarfasciitis or Achilles tendonitis.Downhill running often aggravatesperi-patellar pain syndrome. Run-ning at night or in dim light condi-tions may aggravate mild balanceimpairment. A patient recoveringfrom an ankle injury may need torun in daylight if a proprioceptivedeficit remains.

Gait changes that occur with anincrease in speed work include anincrease in the number of stridesper minute and an increase in

CHART 1Risk Factors

A variety of contributing factors to running injuries shouldbe noted:

• Overuse or training errors - Inexperience - Terrible 2’s

* Too much, too soon, too often, too fast - Intensity

• Miles run per week - Perhaps but may be related to overuse

• Previous running injury • Incorrect shoe • Flexibility issues • Strength issues • Surface issues • Abnormal biomechanics

stride length. Over-striding is one of the most frequenttraining flaws and among other deleterious effects thismay aggravate calf and Achilles tendon problems,hamstring injuries, and increase stress in the anteriortibial muscle group.

Physical Examination The physical examination will lead you to direct

knowledge of what structures are injured. You shouldalso perform a thorough biomechanical examinationand note how well-balanced is the muscle strengthand what muscle groups require stretching orstrengthening.

When performing a physical examination I followthe principles of “Look, Touch, Move.” I start awayfrom the area that I suspect will be most tender andthen work towards it. This limits responses from thepatient anticipating pain.

Shoes It is clear to most that shoes play a role in the

cause, the prevention and the treatment of run-ning injuries. Even Abebe Bikila, the barefoot win-ner of the 1960 Olympic Marathon, decided towear shoes while winning the 1964 OlympicMarathon.

Be sure to examine your running patient’s shoes.How long have the shoes been worn and for howmany miles have they been worn? What is the overallappearance of the shoe? Does it have appropriatepronation protection features? Has the upper shiftedabnormally? Is the sole excessively worn? Is the wearsymmetrical? Do the characteristics of the shoe in-crease the risks for the type of injury that the patienthas? The vast majority of our patients are not world-class athletes and should not do much, if any, runningin racing flats.

The aging shoe exhibits more than just a wornsole. The midsole compresses and loses its shock ab-sorption. The heel may no longer sit perpendicularto the ground. The upper may have holes in it andmay no longer line up properly with the rest of theshoe.

More detailon the role ofshoes and in-juries has ap-peared in previ-ous articles inPodiatry Man-agement. Youmay also up-date yourknowledge byattending anAAPSM shoeworkshop.

Foot Types Different foot types have dif-

ferent basic shoe requirements.The under-pronating high archedfoot presents a higher lateral loadto the shoe and will not do wellwith a spongy midsole and manypronation control devices. Theover-pronating flat foot presentsan excessive medial load to theshoe and often is present withthe problems of medial t ibialstress syndrome, peri-patel larpain syndrome and plantar fasci-itis. The shape of the last shouldalso be matched to the shape ofthe pat ient ’s foot . An over-pronated foot often does best in astra ight lasted shoe, a higharched under-pronated foot doesbetter in a curved last and theneutral foot is most often morecomfortable in a straight lastedshoe.

An ideal shoe for an over-pronating patient should likelyinclude a straight last, be manu-

a 10 minute easy warm-up and gentlestretching after running. In resistantcases, some researchers have recom-mended eccentric stretches. Heel lifts areoften helpful, and the use of orthoticsshould be considered to eliminate tri-pla-nar stress through the Achilles tendon.

During the recovery phase the pa-tient should use relative or absolute rest.An elliptical trainer is often helpful. Thetreadmill should be avoided because thegait alterations that occur are not con-ducive to recovery from this injury.When returning to overground runninga shortened stride may help avoid pain.

Medial Tibial Stress SyndromeUntil recently, the term “shin

splint” was used to refer to manylower leg pains which included bothbone and soft tissue injuries. Medialtibial stress syndrome (MTSS) is amore appropriate and specific termfor what had been called medial shinsplints. It must be distinguished froma tibial stress fracture. Clinical onsetand location of pain help making thediagnosis. Pain is reported at the me-dial aspect of the leg, adjacent to themedial aspect of the tibia. Tendernessis usually found between 3 and 12centimeters above the tip of the medi-al malleolus at the posterio-medial as-

Most Common InjuriesThe most common running injuries

reported are to the knee, calf andAchilles tendon, medial tibia, heel andlower back. The specific injuries mostoften reported include: patello-femoralpain syndrome, calf and Achilles tendoninjury, ilio-tibial band syndrome, medialtibial pain, heel pain and sesamoid in-jury.

Other notable injuries includestress fractures of the metatarsals,tibia, hip and femur. The preliminaryresults of an online survey indicatedthat there has been a recent decreasein patello-femoral pain syndrome(14% vs. 25% in earlier studies) andan increase in ITB syndrome (11% vs.3.9%) and Calf and Achilles Tendonpain (18% vs. 7.9%).

Tips On Selected Injuries

Achilles Tendon & Calf InjuriesThe calf and Achilles tendon are

the most often injured lower leg re-gion. Your patients with this problemshould be advised to avoid hills. Theyshould also avoid shoes that are eithertoo rigid or too soft and be certain tosteer clear of shoes with viscoelasticcompartments or soft air cells. Shoesthat are too soft exhibit an excessivedeformation of the heel. The calca-neus is moving downwards when itshould be on solid ground.

A variety of materials can be used in the fabrication of orthotics for runners.

The flexion stability test is easily per-formed. Hold the heel of the shoe andpress it into a flat surface at about 45-60degrees. The shoe should bend at the ballof the foot. If it bends proximal to thispoint (bottom photo), it fails the test.

often seen horizontal zone of tender-ness in a stress fracture. Periostitismay occur in this location.

The injured structures usually in-clude posterior tibial tendon and mus-cle; however, both the flexor digitorumlongus and flexor hallucis longus mayalso be involved. A bone scan may beused to assist in the diagnosis. Compart-

ment syndromes may also occur in thisregion, but have been covered in past is-sues of Podiatry Management.

The primary causes of MTSS areovertraining combined with excessivepronation. Running on a canted sur-face or excessive track training willplace the higher leg (or outside leg) ata greater risk for this injury.

Your patients should be advised todiminish their training. While runningon soft surfaces has been recommend-ed for this problem, it is not likely to

CHART 7Pribut Pain Staging of Overuse

Injuries in AthletesStage 0. No pain is present before, during or after activi-

ty. Minor discomfort may be experienced at various timesduring training or racing.

Stage 1. Pain or stiffness after activity. The pain is usuallygone by the next day.

Stage 2. Mild discomfort before activity that goes awaysoon after exercise is commenced. No pain is present in thelatter part of the exercise. Pain returns after the exercise iscompleted (starting within 1 to 12 hours later and lasts up to24 hours).

Stage 3. Moderate pain is present before sport. Pain ispresent during sport activity, but is somewhat decreased. Thepain is an annoyance which may alter the manner in whichthe sport is performed.

Stage 4. Significant pain before, during, and after activity.The pain may disappear after several weeks of rest.

Stage 5. Pain before, during, and after activity. The ath-lete has stopped his/her sports participation because of theseverity of the pain. The pain does not abate completely evenafter weeks of inactivity.

Aged orthotics should be replaced

CHART 8Do’s and Don’ts of Winter Running

1. Dress in layers. Use light weight wicking fibers as the layer closest to your body.2. Do wear socks made of synthetic fibers that wick moisture away from your skin to help pre-

vent blisters and athlete’s foot.3. Remember that your head may be responsible for about 40% of heat loss. Keep your head

covered and wear gloves.4. Apply skin protection using sun block and moisturizers as appropriate.5. Don’t forget to replace your fluids on long runs.6. Do fit your running shoes or other sports shoes with the type of sock you intend to wear

them with. Do replace your running shoes often. Replace them at least every 350-450 miles run.7. Do wear sport specific running shoes. Running shoes do not have the lateral support need-

ed for tennis. Help yourself avoid ankle sprains and other injuries.8. Warm up slowly and gently before your runs and especially before doing speed work.9. Be careful running in low light conditions both because of road traffic and uneven pave-

ment, and also be aware of increased balance problems.10. Don’t do speedwork in bone chilling cold. You are risking injury. Most wise runners use

this season for maintenance runs.

be helpful. The foot will pronate moreon softer surfaces, such as grass orsand. Packed dirt would be an idealsurface. I specifically advise againstrunning on concrete. Motion controlshoes should also be recommended.Gentle posterior stretching exercisesmay help, but control of pronation isdirectly related to the cause of this syn-drome. Ice applications following run-ning may be helpful.

Patello-Femoral Dysfunction/Peri-Patellar Pain Syndrome

Patello-femoral pain has longbeen a common running problem,but has troubled fewer runners late-ly. The recommendations for treat-ment remain the same. Assess thebiomechanics of your patient, in-cluding limb length. My usual rec-ommendations include prescribinga decrease in training, avoidance ofdownhill running, a return to run-ning with run/walk intervals,straight leg lifts (10 sets of 10 repe-titions), if needed a motion controlshoe, and possibly orthotics. ■
