Key takeaways
- The American College of Physicians says most new low back pain improves over time whatever treatment you choose, so staying active for a few weeks is a reasonable start if no warning signs appear12.
- In trials pooled by Cochrane, 56% of women with stress incontinence who did pelvic floor muscle training said their leaks were cured, compared with 6% who had no treatment7.
- Vestibular rehabilitation, a set of head, eye and balance exercises, eased dizziness from inner-ear problems in a Cochrane review of 39 trials, and no study reported harm6.
- After a stroke, U.S. heart and stroke groups advise rehab in an inpatient rehabilitation facility when possible, where people typically get about three hours of therapy a day10.
- A good plan of care sets measurable goals and repeats the same tests at the start and end815; with back pain, new leg weakness or numbness or loss of bladder control means see a doctor first2.
Two common problems show why “wait and see” is sometimes the right call and sometimes just lost time.
New low back pain usually eases by itself. In its 2017 guideline, the American College of Physicians (ACP) told doctors that most people with acute back pain get better over time, whatever treatment they pick1.
Bladder leaks when you cough, laugh or lift tend not to work that way. In 2018, Cochrane, an independent network that pools medical research, combined 31 trials of pelvic floor muscle training in 1,817 women7. In the four trials that measured it among women with this “stress” incontinence, 56% of those who trained said their leaks were cured. Only 6% of women who got no treatment said the same7.
This guide goes condition by condition: what to try first, when to book a therapist, when to see a doctor first and how to tell whether therapy is working.
Back pain: start with time and movement, and watch for red flags
The A.D.A.M. Medical Encyclopedia, a physician-reviewed reference, says most people improve or recover within 4 to 6 weeks. It advises against bed rest2.
For new pain, ACP’s first picks are superficial heat, massage, acupuncture or spinal manipulation1. For pain that lingers, it puts exercise, multidisciplinary rehabilitation, acupuncture and mindfulness ahead of any pills, with tai chi and yoga also on the list1.
Does early physical therapy pay off? It depends on how you study it.
A 2012 study in the journal Spine tracked insurance records for 32,070 people who saw a primary care doctor for new back pain3. Those who started physical therapy within 14 days had lower risks of later surgery, injections, opioid use and advanced imaging. Their total health costs averaged $2,736 less than those who started therapy later3.
But a records study can’t rule out that people who choose early therapy differ in ways the data miss. Randomized trials, which assign people to groups by chance, tell a more modest story.
In a trial of 220 adults with new back pain and no warning signs, four early therapy sessions cost about $580 more per person over a year. They also slightly improved quality of life, and the authors judged them cost-effective4. In a 2018 trial of 119 military service members, early therapy eased disability more at four weeks, but by one year the groups looked the same. Total costs were similar, and back-related costs ran higher with early therapy5.
So the evidence splits by study design. The big records study points to savings. The smaller randomized trials point to a modest early benefit that may cost a bit more.
The practical lesson: if your back pain is new and you have no red flags, staying active for a few weeks is reasonable. The encyclopedia advises contacting a provider if an episode lasts longer than 4 weeks2. That’s a sensible point to book a therapist, too.
Dizziness from the inner ear responds to targeted exercise
Some dizziness starts in the vestibular system, the balance sensors in your inner ear. When one side is damaged, for example by an inner-ear infection, the brain has to relearn how to read the signals.
Vestibular rehabilitation is training for that relearning. A therapist may have you deliberately bring on brief dizziness so the system gets used to it. Other drills pair head turns with eye movements or challenge your balance and walking, and you learn how your condition works6.
A 2015 Cochrane review pooled 39 randomized trials with 2,441 people who had inner-ear problems on one side6. In four trials that tracked how often people felt dizzy, the odds of improvement were about 2.7 times higher with rehab than without it6.
The reviewers judged the case for safety and benefit moderate to strong. Where trials checked back in 3 to 12 months later, the gains had lasted, and no study reported harm6.
One common cause needs a different fix. Benign paroxysmal positional vertigo (BPPV) brings brief spinning spells set off by certain head positions. Here, repositioning maneuvers, in which a clinician guides your head through a series of positions, gave faster relief than exercise6. For lasting recovery, doing both worked well6.
Bladder leaks: pelvic floor training is the first fix to try
Stress incontinence means leaking when pressure on the bladder jumps, as with a cough, sneeze, laugh or jump. Pelvic floor muscle training teaches you to find, squeeze and strengthen the muscles that support the bladder.
The 2018 Cochrane review is one of the clearest wins in rehab. Beyond the cure rates above, 74% of women with stress incontinence who trained reported a cure or improvement, compared with 11% of untreated women7. Training cut leaks by about one episode a day, side effects were rare and minor, and the evidence was mostly of moderate quality7.
There are limits. Programs varied a lot in content and length7. Only one trial studied urgency incontinence alone, the sudden “I have to go now” kind. It had no cure data, though training seemed to cut leaks7.
When should you see a pelvic floor therapist? Our suggestion: if about three months of daily practice brings no progress, or you aren’t sure you’re squeezing the right muscles. Losing bladder control along with back pain and numbness in the legs or buttocks is different. Those are red flags, so see a doctor right away2.
After surgery: therapy starts within a day, and some torn ligaments show healing
After a total knee replacement, rehab begins almost at once. A 2020 guideline from the American Physical Therapy Association (APTA) advises starting physical therapy within 24 hours of surgery, before you leave the hospital8. APTA funded the guideline, though it says it played no role in the recommendations8.
Its only “strong” recommendation is motor function training: practicing balance, walking and moving both legs evenly8. It also advises supervised therapy after surgery, with the setting chosen for your safety and home situation. Strength training should begin within about a week and progress to high intensity8.
The same guideline advises against continuous passive motion machines, which bend the knee for you, after a routine knee replacement8. If a program leans on gadgets over active work, ask why.
A torn anterior cruciate ligament (ACL), a key stabilizing ligament in the knee, raises a different question: surgery first, or rehab first?
In the KANON trial, 121 recreationally active adults aged 18 to 35 with a fresh, MRI-confirmed ACL tear were assigned by chance to early reconstruction or to rehab, with the option of surgery later9. By five years, 51% of the rehab-first group had chosen surgery, and knee scores were similar across the groups, according to a research summary from the clinician-education site Physio Network9.
A later analysis found signs of ligament healing on MRI scans in 16 of the 30 rehab-group members who still hadn’t had surgery at two years9. One trial in young recreational athletes can’t settle the question for everyone, but it shows that skilled rehab is a real option, not just a waiting room.
After a stroke, where you do rehab matters
About 800,000 Americans have a stroke each year. More than 80% survive, and many live for decades with some disability, according to figures cited in 201610.
Those guidelines, from the American Heart Association and American Stroke Association, made one choice central: if you can, do your rehab in an inpatient rehabilitation facility instead of a skilled nursing facility. The groups called the evidence behind that advice strong10.
The difference is intensity. A day in an inpatient rehab facility usually means around three hours of therapy from a mix of specialists, from physical, occupational and speech therapists to nurses, psychologists and social workers10. The guidelines also say no one should go home before joining a formal falls-prevention program10.
The lead author, Carolee Winstein of the University of Southern California, said families should push for that setting unless there’s a good reason against it, such as being too ill to take part11. Before discharge, ask: “Does my family member qualify, and if not, why not?”
Concussion: brief rest, then gentle movement
CDC’s HEADS UP guidance for children, updated in 2025, rejects long rest in a dark room. It advises limiting screens and hard activity for a day or two12. Then it encourages light activity, such as short walks, scaled back if symptoms flare12.
Most children feel better within 2 to 4 weeks12. CDC tells clinicians to consider a concussion specialist if symptoms worsen at any point or haven’t cleared after 2 to 4 weeks13. A history of several concussions, or of migraines, depression or anxiety, can also justify a referral13.
For athletes, CDC lays out a six-step return to sport. You move up only when the current step brings no new symptoms. If symptoms return, stop, contact your provider and, once they settle, restart one step back13.
Danger signs call for emergency care, not rehab. Call 911 or go to an emergency department for seizures, repeated vomiting, a headache that keeps getting worse, slurred speech, weakness or numbness, growing confusion or drowsiness, or one pupil larger than the other14.
Rehab or doctor? A condition-by-condition guide
This table is our own, built from the sources above. Use it to pick a next step, not to diagnose yourself.
| Situation | Try first | See a therapist if | See a doctor first or now if | Good rehab includes |
|---|---|---|---|---|
| New low back pain | Stay active; heat; no bed rest12 | Not better after about 4 weeks2 | Loss of bladder or bowel control; leg weakness or numbness; unexplained fever; a cancer history; pain after a hard fall2 | Exercise you can keep doing and coaching to stay active12 |
| Spinning or unsteadiness from the inner ear | A diagnosis, since BPPV and other inner-ear problems need different fixes6 | Once an inner-ear cause is found; rehab beat no treatment in trials6 | New, unexplained dizziness should be checked first; our 911 guide lists emergency signs | BPPV maneuvers when needed; eye, head and balance exercises6 |
| Leaks with coughing, laughing or lifting | Daily pelvic floor exercises7 | No progress after about 3 months (our suggestion) | Loss of bladder control with back pain and leg numbness2 | Help finding the right muscles; a program that progresses7 |
| Knee replacement | Exercise before surgery8 | Always: therapy should start within 24 hours8 | Anything your surgeon lists as a warning sign | Balance and walking practice, strength work, tests at start and end8 |
| Torn ACL | Talk through rehab-first vs. early surgery9 | Rehab-first is a tested option9 | A doctor should confirm the tear, as MRI did in the trial9 | A rehab program with the option of later surgery9 |
| Stroke | Not a wait-and-see problem | Before discharge, ask about an inpatient rehab facility1011 | New stroke symptoms: our 911 guide lists them | About 3 hours a day of team therapy; a falls program10 |
| Concussion | Ease off screens and hard activity for 1 to 2 days, then light activity12 | Symptoms not cleared after 2 to 4 weeks1213 | Danger signs, such as repeated vomiting or a worsening headache14 | A step-by-step return to activity13 |

A good plan of care has numbers in it
Your first visit should end with a plan, not just a handout. Under Medicare rules, a therapy plan of care must list your diagnoses and measurable long-term goals, plus the type, amount, duration and frequency of treatment15. Ask for the same structure whoever pays.
Look for outcome measures, the tests that show whether you’re changing. APTA’s knee replacement guideline names three: KOOS JR, a short knee questionnaire; a 30-second chair stand; and the Timed Up and Go test, which times how fast you rise from a chair, walk a short way, turn and sit back down8. It advises running them at least at the first visit and the last8.
Other problems have their own yardsticks, such as the Oswestry Disability Index for back pain5 and the Dizziness Handicap Inventory6. If no one measures anything, you can’t tell whether therapy is working.
The home program is the part you own. A good therapist writes it down and adjusts it as you improve.
Signs rehab isn’t working (our checklist). Ask for a re-evaluation if:
- your retest scores haven’t moved after several weeks of honest effort;
- every visit is passive treatment, and the plan never changes.
Signs something else may be wrong. Go back to your doctor if:
- with back pain, new red flags appear: weakness or numbness, loss of bladder or bowel control, unexplained fever or weight loss, or pain that wakes you at night2;
- a back-pain episode feels different from and worse than past ones, or lasts longer than 4 weeks2;
- after a concussion, symptoms get worse at any point13.
The evidence, rated, and why rehab fits natural health
| Claim | Evidence level | What it rests on |
|---|---|---|
| Pelvic floor training cures or improves stress incontinence in women | 31 trials, mostly moderate-quality evidence7 | |
| Vestibular rehab eases dizziness from one-sided inner-ear problems | 39 trials; reviewers rated it moderate to strong6 | |
| Most new low back pain improves with time, whatever the treatment | ACP’s review of trials1 | |
| Balance and walking practice after knee replacement improves recovery | The APTA guideline’s one strong recommendation8 | |
| Inpatient rehab facilities are the better choice after a stroke | Rated strong in the 2016 heart and stroke guidelines10 | |
| Rehab first, with optional later surgery, works as well as early ACL surgery in young recreational athletes | One main trial of 121 people9 | |
| Early physical therapy for new back pain eases disability sooner | Better at 4 weeks in one small trial, gone by 1 year5 | |
| Early physical therapy for new back pain saves money | Conflicting: savings in one records study; two small trials found similar or higher costs345 |
Rehab is natural health practiced in a clinic. ACP’s first choices for back pain are drug-free1. Pelvic floor training cures many leaks without a pill or an operation7. The KANON trial even caught torn ligaments showing signs of healing without surgery9.
Your body does the healing. A skilled therapist sets the dose, the order and the timing, and tells you when it’s time to stop pushing and see a doctor.
Questions readers ask
My back has hurt for 10 days. Should I see a physical therapist?
Without red flags, waiting a bit and booking now are both reasonable. In one trial, early therapy brought a slight gain in quality of life at a higher cost4. If it isn’t easing by about 4 weeks, see a clinician2.
Do I need surgery for a torn ACL?
Not always. In the KANON trial, about half of the young adults who tried rehab first still hadn’t had surgery five years later, and their knee scores were similar9. Talk through your sport and goals with your surgeon and a therapist.
Can I learn pelvic floor exercises on my own?
Many people start with written instructions. Programs in the Cochrane review varied widely7. If leaks don’t improve after a few months, or you aren’t sure you’re using the right muscles, a pelvic floor therapist can check your technique.
The bottom line
Not every ache needs a therapist. New back pain without red flags often fades with time and movement.
Other problems respond far better to skilled rehab than to waiting: inner-ear dizziness, bladder leaks, recovery from joint surgery and stroke. Choose a therapist who measures your progress, teaches you a home program and sends you back to a doctor when the warning signs say so.
