THERAPEUTIC EXERCISE · FROM MY PT NOTES
Therapeutic Exercise
Three real-world cases on stairs, lifting and turning strength gains into useful function. Answer each question before revealing the discussion.
Use this chain: Patient’s task → relevant finding → exercise with a purpose → repeat the task. An impairment measure helps explain the problem; the functional goal tells you whether the plan is helping.
Case 1: Knee pain on stairs — should I treat the ankle or hip?
Casey, 48, wants to descend the 12 stairs at home comfortably while using the handrail. The supervising PT has assessed the pain as patellofemoral pain and found no restriction to graded exercise. During a step-down, Casey’s heel rises early and the knee moves forward less on that side.
Pause and decide: What would make you assess above or below the knee—and what would justify treating what you find?
Reveal the findings and reasoning
What you learn next: Weight-bearing ankle dorsiflexion is more limited on the symptomatic side. Knee-extensor capacity is also reduced. The hip assessment does not identify a meaningful limitation for this task.
Reason it through: The ankle finding gives you a hypothesis: limited motion may affect how Casey manages the step. It does not prove the ankle caused the knee pain. Consider an ankle intervention if the examination supports it, then recheck the task. Keep education, appropriate knee loading and step practice in the plan. Hip exercise may also help when the assessment and goals support it; a normal strength test alone does not rule it out.
Put it into practice: Try a lower step with the rail to find a manageable starting task. If you trial an ankle intervention, recheck the same step setup before changing other variables. Easier performance on a lower step reflects a changed demand; it does not identify the source of pain.
Reassess: Use the same step height, rail use and number of repetitions. Compare symptoms, control, effort and confidence; later check the actual home-stair goal.
Make it click: Assess nearby joints when the task and examination give you a reason. Treat a relevant finding, not simply a nearby joint.
Case 2: How does this exercise help me lift my child?
Morgan, 35, has persistent low-back pain and wants to lift a toddler from the floor and carry them across the room. The supervising PT has screened and evaluated Morgan and cleared graded lifting. Morgan can do the prescribed bridge but still avoids floor lifting.
Pause and decide: If the bridge is getting easier, why might the patient’s goal still feel out of reach?
Reveal the findings and reasoning
What you learn next: Morgan has practiced only on the mat. A light box lifted from a raised surface feels manageable, but lifting from the floor feels threatening.
Reason it through: A bridge can train hip and trunk muscle performance when assessment identifies a relevant need. Improvement in the bridge alone does not demonstrate better lifting. The bridge does not reproduce lifting from the floor or carrying. Add graded practice with a box: choose a manageable load and starting height, then work toward the actual task. Explain the purpose of each exercise in the patient’s words.
Put it into practice: “We are practicing with this box to work toward lifting your child. We will keep the bridge if it addresses a relevant need.” Progress one useful demand, such as lowering the starting surface, while keeping the load and carry distance steady. Select the starting dose from the observed response and recovery.
Reassess: Record the box load, start height, carry distance, effort and confidence, plus symptoms during practice and afterward. Progress toward the agreed real-life goal rather than chasing a larger exercise number.
Make it click: Name the exercise’s job: build capacity, practice the task, or both. If you cannot explain the connection, reconsider the choice.
Case 3: They’re stronger. Why are stairs still hard?
At follow-up, Casey’s knee-extension strength has improved. The first few step-downs look easier, but a full flight at home still feels difficult. Casey has ten minutes for exercise and has been completing only two of the six prescribed exercises.
Pause and decide: Before adding more resistance, what information is missing?
Reveal the findings and reasoning
What you learn next: The clinic has tested only a few repetitions. Casey reports that difficulty builds later in the flight, and the home program takes too long to finish.
Reason it through: The strength change is useful, but it does not establish that the stair goal has improved. Reassess repeated stepping, symptom behavior, confidence, rail use and the actual program completed. Reconsider the working explanation if the findings do not fit.
Put it into practice: Agree on a shorter plan Casey can carry out. Prioritize an exercise for the remaining capacity need and graded stair practice; keep supporting exercises only when they have a clear purpose. If repeated stepping reveals a tolerance limit, adjust practice volume or rest to match that finding rather than automatically adding weight.
Reassess: Repeat a consistent stair task and track repetitions or steps, assistance, effort, confidence and recovery. Compare it with Casey’s experience at home. New or worsening findings require reassessment, not simply a harder program.
Make it click: Measure the goal as well as the impairment. A stronger muscle is progress; the patient’s task tells you whether the plan is transferring.
Can you explain the exercise in one sentence?
“We chose ___ because ___ is limiting your ability to ___. We will check ___ to see whether it helps.”
If the explanation stops at “it strengthens the glutes,” ask the next question: why does that capacity matter for this person’s task?
