Physical pain is one of the fastest routes to reduced productivity
For business professionals, physical discomfort directly undermines performance. Shoulder stiffness, lower back pain, sports injuries — these are not minor inconveniences. Yet despite how common physical therapy is as a treatment option, many people remain uncertain about what it actually involves. What happens during a session? How long does treatment take? Is the discomfort normal?
Physical therapy is not a vague category of massage or generic exercise guidance. It is a scientifically grounded, specialist-led approach that uses deep knowledge of the body's structure and function to assess individual conditions, develop targeted treatment plans, and pursue both recovery and injury prevention.
This article draws on an explanatory video by Dr. Courtney Mirs, a Doctor of Physical Therapy and certified orthopedic clinical specialist, to answer the questions people most commonly ask about PT — from duration and discomfort to condition-specific approaches and emerging techniques.
How long does physical therapy take?
The question most people ask first: how many sessions will this require? According to Dr. Mirs, the typical patient goes through around six to eight weeks of treatment — but this is an average, not a fixed timeline.
The variables that matter most are the type and severity of the injury, what recovery looks like for that condition, and — critically — how consistently the patient does their prescribed home exercise program. "To finish physical therapy quickly, you need to follow your physical therapist's instructions and keep up with home exercises," Dr. Mirs emphasizes.
Physical therapy is not passive treatment. Patient participation is a primary driver of outcome.
Is it normal for exercises to hurt?
When starting new movements in PT, mild soreness or tightness is normal. It functions similarly to delayed-onset muscle soreness after exercise: unfamiliar movements create temporary discomfort that typically resolves within a day or two.
Physical therapists often use a 0–10 pain scale. A level of 2 or 3 is generally considered acceptable during exercise. If pain reaches higher levels or continues to worsen, communicate that immediately with your therapist — the program needs adjustment.
Why PT requires scientific training
Dr. Mirs' answer to why PT education is so science-intensive: "Because what we do is science." Physical therapy draws on physics (lever principles, force distribution), pharmacology (understanding how medications affect patient response), chemistry (biological reactions), and research methodology (applying evidence-based practice). The field has progressively moved toward doctoral-level training to ensure the quality and rigor of care.
PT vs. occupational therapy vs. personal training
Physical therapy vs. occupational therapy: Dr. Mirs offers a useful analogy — PT helps you get from point A to point B (mobility, movement, gross motor function). Occupational therapy helps you perform specific activities at those destinations (daily living tasks, fine motor skills). Both are important and frequently work in coordination.
Physical therapy vs. personal training: The decisive difference is that physical therapists can perform medical assessment and diagnosis. Dr. Mirs recommends seeing a PT first to identify the root cause of any dysfunction or pain before beginning general gym training. A personal trainer can guide exercise effectively but cannot diagnose medical conditions or prescribe clinical treatment.
Condition-specific approaches
Lower back pain: "Bad back" is an oversimplification that Dr. Mirs actively resists. Lower back pain has many causes — muscle imbalance, limited joint mobility, movement pattern problems — and effective PT begins with a detailed assessment to identify which. Treatment combines targeted exercise, manual therapy, and movement retraining, with prevention built in through posture instruction and home programs.
TMJ (jaw pain): Many people are unaware that physical therapists treat jaw dysfunction. Because the jaw is a joint surrounded by muscles, the same principles apply. Treatment focuses on releasing tension in the temporal and masseter muscles, and teaching patients to maintain a relaxed jaw position: tongue touching the roof of the mouth, teeth slightly apart, lips closed.
Nerve compression: Most nerve compression issues are posture-related. PT addresses this through postural correction, muscle strengthening to support the spine, and movement modification. PT cannot change bone structure or disc anatomy, but it can significantly reduce symptom severity by reducing mechanical load on the nerve.
MCL injuries: Grade 1 (minor stretch) typically responds well to conservative treatment. Grade 3 (near-complete tear) requires realistic expectations — full tissue healing is limited, and scarring may occur. PT focuses on joint mobility, surrounding muscle strengthening, and proprioceptive retraining to restore functional stability.
Postpartum urinary incontinence: A direct result of pelvic floor changes during pregnancy and delivery. Specialized physical therapists assess pelvic floor function and teach correct activation technique (such as Kegel exercises). This is a treatable condition, not one to simply accept.
Scoliosis: Spinal curvature can be addressed conservatively through targeted stretching, strengthening, posture correction, and breathing techniques. Methods like the Schroth Method are specifically designed for scoliosis management.
Phantom limb pain: Mirror therapy uses visual feedback — reflecting the intact limb so the brain perceives the absent limb moving normally — to reduce pain by leveraging neural plasticity.
Emerging techniques
Aquatic therapy: Water's buoyancy reduces joint loading, allowing patients to perform movements that would be too painful on land. Especially effective for chronic pain and elderly patients. The eventual goal remains land-based function.
VR therapy: Virtual reality is showing particular promise for balance rehabilitation — simulating urban environments with unexpected obstacles trains fall-prevention responses. VR is also being studied for pain modulation in chronic conditions, with early results showing reduced pain perception through immersive calming environments.
Blood Flow Restriction (BFR) training: Specialized cuffs restrict (but do not eliminate) blood flow to a limb during low-load exercise, causing metabolite accumulation that stimulates muscle growth signals similar to heavy training. This allows effective strength recovery after injury or surgery when high-load training is not yet possible. BFR requires qualified supervision and is contraindicated for patients with clotting risk.
Cupping: Low scientific evidence base, but may provide temporary symptomatic relief. Accessible and low-cost. Most useful as an adjunct to treatment, not a standalone approach.
Kinesiology tape: Elastic tape that supports muscles and joints, improves blood and lymph circulation, and stimulates proprioception. Effects include some placebo component. Useful for some patients in some applications.
The psychological dimension
Chronic pain involves the brain, not just the body. Dr. Mirs notes that anxiety and psychological stress can sensitize the brain's pain processing centers, leading to amplified responses to stimuli that would normally be ignored. Physical therapy for chronic pain often benefits from coordinating with psychologists or mental health professionals. "Pain is never just in your head," Dr. Mirs emphasizes — but the mind is always part of the picture.
Summary
Physical therapy is not passive treatment. Recovery depends on active patient engagement, honest communication with your therapist, and consistent home exercise. Treatment typically runs 6–8 weeks, though the range is wide. Mild exercise-related discomfort is expected and normal; worsening pain requires immediate discussion.
The scope of PT is broad — from lower back pain to jaw disorders, from postpartum recovery to phantom limb pain — and the toolkit continues to expand with VR, BFR, and other emerging techniques. For business professionals dealing with physical discomfort that limits their performance, understanding what PT can offer is the first step toward making better use of it.
