Warm water takes load off your joints and lets you move with less pain, which is why hydrotherapy is used in rehabilitation of the knee and back and after injuries and surgery. This guide explains how it works, who benefits, what the evidence really supports, and when it may not be suitable for you.
Quick answer
Hydrotherapy means doing therapeutic exercises in a warm pool under the supervision of a physiotherapist. Water reduces the body weight going through your joints and gives gentle resistance, so you move with less pain and strengthen gradually. Evidence (such as a Cochrane review) shows a small short-term improvement in pain for people with knee and hip osteoarthritis, and it is usually used as a complement to land-based exercise, not a replacement.
What is hydrotherapy?
Hydrotherapy, or aquatic therapy, is a form of physiotherapy performed in a dedicated pool at a warm temperature (usually around 33–35 °C), where the therapist sets a programme of movement, balance, strengthening and walking exercises in the water. It differs from recreational swimming: the session is designed for a specific therapeutic goal for each patient.
How does water help recovery?
1Buoyancy reduces load
The deeper you are immersed, the less weight goes through your joints; at chest level most of your body weight is offloaded, so you can move with less pain.
2Warmth relaxes muscles
Warm water helps muscles relax and reduces stiffness so you move more freely.
3Gentle, controllable resistance
Water resists movement in every direction, strengthening muscles without weights, and intensity can be adjusted by changing speed and depth.
4Water pressure reduces swelling
Hydrostatic pressure may help reduce swelling in the limbs.
5Greater balance safety
Water supports you and lowers the fear of falling, so you can train walking and balance with confidence.
6An easier start to exercise
People who find land exercise too painful can start in water and progress gradually to land.
Who may benefit from hydrotherapy?
| Condition | How it may help |
|---|---|
| Knee and hip osteoarthritis | Movement and strengthening with less joint load; a Cochrane review found a small short-term improvement in pain compared with no intervention. |
| Low back pain (after the acute phase settles) | Trunk strengthening and mobilising without stressing the spine. |
| After surgery or fractures | Gradual return of movement, depending on the surgeon’s clearance and wound healing. |
| Sports injuries | Early rehab that maintains fitness while reducing load. |
| Poor balance and older adults | Walking and balance training in a safer environment. |
| Neurological and muscular conditions | Low-load movement and strengthening according to the treating team’s plan. |
These are general examples; whether hydrotherapy suits you is decided by the therapist after assessment.
What does the scientific evidence say?
One of the clearest pieces of evidence is a Cochrane review (2016) of randomised trials of aquatic exercise for people with knee and hip osteoarthritis, which concluded a small short-term improvement in pain compared with control groups. There was not enough data to confirm long-term benefits.
What does this mean in practice?
Hydrotherapy is a safe and helpful option for many people, especially early on when pain limits land exercise — but it is not a magic cure. The best results come when it is combined with land-based strengthening and a regular home programme.
What does a hydrotherapy session look like?
- 1Assessment and clearance
The therapist checks that your condition allows you into the water (closed wound, no infection, no medical restriction) and sets your goals.
- 2Warm-up
Light walking and joint mobilisation in the water to raise body temperature and prepare the body.
- 3Therapeutic exercises
Range-of-motion, strengthening and balance exercises such as walking in water, side steps and knee and hip exercises.
- 4Cool-down and review
Relaxation exercises and a check of your response after the session, then adjusting the programme for next time.
When is hydrotherapy not advised?
Check with your doctor or therapist before getting in the water if you have
- Open wounds, skin infections or an active infection.
- A fever or contagious illness.
- Uncontrolled heart disease or blood pressure.
- Uncontrolled seizures.
- Uncontrolled bladder or bowel incontinence.
- A severe fear of water or being unable to stand safely (judged case by case, with assistance).
This is a general, not exhaustive, list — which is why hydrotherapy always starts with an assessment of whether it is safe for you.
Tips before your hydrotherapy session
- Tell your therapist about all your conditions, medication and any wounds or skin allergies.
- Shower before entering, and bring suitable swimwear and a towel.
- Avoid a heavy meal at least an hour before, and drink enough water.
- Stop and tell your therapist if you feel dizzy, sharp pain or shortness of breath.
- Keep up your home exercises — they complete the work of the sessions.

Frequently asked questions
Do I need to know how to swim?
No. Exercises are done in an area deep enough to stand safely, under your therapist’s supervision, and no swimming skill is required.
Is hydrotherapy better than land exercise?
Not necessarily. It is an excellent complement, especially when pain is severe or weight-bearing is difficult, but land-based strengthening is a core element in most cases.
How many sessions do I need?
It depends on your condition and goals. Your therapist sets the number after assessment and adjusts it to your response.
Is it suitable for older adults?
Often yes, because water offers more support and safety, provided your doctor or therapist agrees after reviewing your general health.
Does it help with weight loss?
It may help as part of a regular activity programme, but it is not a treatment for obesity on its own — weight loss depends on diet and overall activity.
Can I go in the water after surgery?
Only after the wound has healed and with clearance from your surgeon and therapist, following the rehab protocol for your operation.
