Hydrotherapy Treatment FAQ

Getting started with hydrotherapy at Advantage Physio is straightforward. You can self-refer directly — you do not need a GP referral to access our physiotherapy services, although if you have a referral letter or relevant medical records relating to your condition, please bring these along as they will assist your assessment. 

To book, contact our clinic to arrange an initial assessment appointment, during which your physiotherapist will evaluate your condition, discuss your symptoms and goals, and determine whether hydrotherapy is appropriate for you. If it is, they will develop a personalised treatment plan and schedule your sessions. We aim to get new patients seen as quickly as possible and are always happy to answer questions about our services before you book.

Hydrotherapy and aqua aerobics are both water-based activities, but they are fundamentally different in purpose and approach. Aqua aerobics is a group fitness class conducted in a standard swimming pool, focused on cardiovascular exercise and general fitness using the resistance of the water. Hydrotherapy is a clinical treatment conducted in a specially heated therapeutic pool, with each patient assessed individually and given a bespoke programme of exercises and movements designed to address their specific condition. 

Hydrotherapy sessions are led by a qualified physiotherapist and are entirely focused on rehabilitation, pain management, and functional improvement. The pool temperature is also different: hydrotherapy pools are significantly warmer to provide the therapeutic benefits described. The two activities are not interchangeable from a clinical perspective.

Yes — hydrotherapy is used with children across a range of conditions, including cerebral palsy, developmental delay, juvenile arthritis, hypermobility conditions, and post-surgical rehabilitation. The warm water environment is often particularly well-tolerated by children who find land-based physiotherapy challenging or uncomfortable, and many children find the sessions enjoyable rather than daunting. 

Paediatric hydrotherapy requires a physiotherapist with appropriate paediatric training and experience, and sessions are always conducted with parental involvement and consent. If your child has been referred for physiotherapy and you would like to know whether hydrotherapy is appropriate for their condition, please contact Advantage Physio to discuss — we can guide you on the most suitable treatment approach.

The therapeutic temperature of a hydrotherapy pool — typically 33–36°C, which is warmer than a standard swimming pool — provides significant physiological benefits beyond simply being comfortable. The warmth causes vasodilation, increasing blood flow to muscles and soft tissues, which speeds healing and reduces inflammation. Muscle spasm and tension are significantly reduced in warm water, allowing greater range of movement and making exercise less painful. 

The hydrostatic pressure of the water also provides a gentle compression around the body, which helps reduce swelling in affected limbs and joints. The combined effect of buoyancy, warmth, and hydrostatic pressure creates a therapeutic environment that simply cannot be replicated on land — which is why hydrotherapy remains a valuable and well-evidenced treatment modality for so many conditions.

While hydrotherapy is safe and beneficial for a wide range of conditions, there are some circumstances where it is not appropriate or requires additional medical clearance. These include: open wounds or skin infections; uncontrolled epilepsy; severe heart conditions or cardiovascular instability; urinary or faecal incontinence where a pool cannot be safely used; active infections with fever; and certain severe respiratory conditions. 

Some conditions require specific precautions but do not rule out hydrotherapy — your physiotherapist will conduct a thorough assessment to determine whether hydrotherapy is safe and appropriate for you and, if necessary, will liaise with your GP or consultant. Patient safety is always our first priority at Advantage Physio.

The number of sessions required depends entirely on your condition, its severity, your rehabilitation goals, and how you respond to treatment. For post-surgical rehabilitation — such as after a hip or knee replacement — a typical course might involve eight to twelve sessions over six to eight weeks, alongside land-based physiotherapy. 

For chronic conditions such as arthritis or back pain, some patients benefit from a defined course of treatment while others find that ongoing, less frequent sessions help them maintain mobility and manage symptoms long term. After your initial assessment, your physiotherapist at Advantage Physio will discuss a recommended treatment plan with you and review your progress regularly, adjusting the programme as you improve.

NHS hydrotherapy services do exist but access is limited, and many NHS physiotherapy departments have closed or reduced their hydrotherapy pools due to funding and maintenance costs. Waiting times for NHS hydrotherapy can be substantial, which is a significant barrier for patients who need rehabilitation promptly — particularly those who have recently had joint replacement surgery. 

Many patients choose to access hydrotherapy through private physiotherapy clinics such as Advantage Physio, which allows them to begin treatment much sooner, have sessions scheduled at a frequency appropriate to their condition, and receive the dedicated one-to-one attention that is often not possible in a group NHS setting. We can advise you on what is appropriate for your situation and discuss costs during your initial consultation.

Before your first session, your physiotherapist will conduct an assessment to understand your condition, functional limitations, and rehabilitation goals. This ensures your hydrotherapy programme is tailored to your specific needs and that any contraindications are identified. During the session itself, you will be in a warm water pool (around 33–35°C) with your physiotherapist who will guide you through a series of specifically designed exercises and movements. 

Sessions typically last 30–45 minutes. The water temperature and buoyancy mean that many patients experience significant pain relief and freedom of movement that surprises them — it is often described as the first time in months they have moved without significant discomfort. You should bring a swimming costume or shorts, a towel, and a change of clothing.

Hydrotherapy is beneficial for a wide and diverse range of musculoskeletal, neurological, and chronic conditions. It is commonly used in the rehabilitation of hip and knee replacements, helping patients regain strength, range of movement, and confidence with mobility earlier than would be possible with land-based exercises. 

Other indications include: osteoarthritis and rheumatoid arthritis, where the offloading effect of water significantly reduces joint pain during exercise; back pain and disc conditions; multiple sclerosis and neurological conditions where muscle weakness or spasticity limits land-based movement; sports injuries; post-fracture rehabilitation; and chronic pain syndromes. The gentle, controlled environment of hydrotherapy is also well-suited to older adults and those who find land-based exercise intimidating or painful.

Hydrotherapy treatment is a form of physiotherapy conducted in a warm water pool, using the unique physical properties of water — buoyancy, resistance, and hydrostatic pressure — to facilitate movement, reduce pain, and support rehabilitation. The key difference from land-based physiotherapy is that the buoyancy of water reduces the effective weight bearing through joints and limbs, allowing patients to perform exercises and movements they might not be able to manage on land. 

The warmth of the water (typically 32–36°C) relaxes muscles and increases circulation, enhancing the therapeutic effect. Hydrotherapy is a valuable complement to standard physiotherapy for a wide range of conditions, and is particularly effective in the early stages of rehabilitation when weight-bearing is restricted.
