PRECAUTIONS TO HIGH INTENSITY EXERCISE
LIMB SPECIFIC; AVOID HIGH INT REHAB INVOLVING AFFECTED LIMB:
-fracture
-osteomyelitis
-avascular necrosis
-osteosarcoma
-bone metastases
-DVT within 6 weeks with anticoagulation
-abdominal precautions or chronic conditions (hernia) (avoid Valsalva) * have pts count, talk out loud, or participate in patterned breathing to avoid Valsalva
-severe OP or compression fracture (avoid spinal flexion and rotation) ** note that avoiding all activity is not good
-moderate or severe non-proliferative diabetic retinopathy (avoid valsalva and maintain BP <150/100)
-aortic aneurysm (no lifting >75 lbs, avoid valsalva, maintain BP <150/100)
Joint replacement precautions
-HIR to the affected limb immediately after surgery
-monitor pain, swelling, and incision healing to determine progression or modification
-if pain is limiting factor –> load the joints distal and proximal to the joint replacement
-can also perform HIRT in non-WB positions
WBAT precautions for HIRT
-apply HIR principles to affected limbs through closed chain activities (within patient’s tolerated limits)
Surgically stabilized fractures precautions:
ex: ORIF
-immediately apply HIR principles to open-chain exercises involving the non-affected areas of the limb
-strengthen the adjacent areas and try not to stress the actual incision
-may be able to introduce HIR principles to affected area of limb after 2 weeks
Acute or chronic pain HIRT precautions
-alternate sides or types of activity to avoid excessive pain increases; work within non-painful ranges
-try an ECCENTRIC focus
ex: stand up using their arms, then have them sit back down without their arms while focusing on quad control
-usually CONCENTRIC portion is more painful
Cognition precautions to HIRT
-modify environment
-monitor your patient’s energy levels - schedule when they are at their highest mental and physical energy levels
-simplify/minimize verbal info - 1-step commands, visually demonstrate exercises, ask patient to copy your movements
-have a back up plan –> plan for more exercises or activities than you anticipate needing during session so you can change up the task to keep your patient engaged
PA considerations moderate non-proliferative diabetic retinopathy:
-limit increases in BP
-avoid valsalva
-avoid jarring activities like boxing
-maintain BP below 150/100
PA considerations proliferative diabetic retinopathy:
-limit increases in BP
-avoid valsalva
-avoid jarring activities like boxing
-avoid high impact activities or activities that raise intra-ocular pressures: high impact aerobic dance, weightlifting, jogging, boxing, racquet sports, scuba diving, trumpet playing, rollercoasters, head-down activities
-encourage low impact activities: swimming, walking, low-impact aerobic dance, stationary cycling, endurance exercise
Possible CI’s of cancer:
-bone metastasis sites –> concern for pathological fractures
-tumors in targeted strength training area
-consider that meds could affect long bone strength
MSK CI’s
-recent fractures < 6 weeks
-unstable fxs
-osteomyelitis: no high intensity strength training on involved limb
-AVN: not on the involved limb
-wounds with exposed tendon or muscle on involved joint
-compression fxs (maintain neutral alignment of the joint)
-weight bearing restrictions with graft or fx sites (open chain, iso only)
-Marfan syndrome (CT disorder)
Possible surgical contra-indications:
CRANIOTOMY (< 6 weeks)
o No bending over
o No lifting >10 pounds
o No Valsalva
ABDOMINAL PRECAUTIONS (< 6 weeks)
o No sit-ups/crunches
o No Valsalva
o No lifting >10 lbs
STERNAL PRECAUTIONS (< 6 weeks) (ex: after CABG)
o No UE high-intensity
o No Valsalva
o No lifting >10 lbs
Medications: possible precautions
