Swimming for Post-Stroke Rehabilitation: Current Applications of Aquatic Physical Therapy in Taiwanese Hospitals

Introduction

Taiwan sees approximately 30,000 new stroke patients each year, and post-stroke rehabilitation is key to helping patients regain their daily living functions. Traditional land-based physical therapy has a well-established system, but in recent years, aquatic physical therapy (hydrotherapy / aquatic physical therapy) has been gradually introduced at several Taiwanese medical centers, opening a new therapeutic window for stroke rehabilitation. The unique physical properties of the aquatic environment offer therapeutic benefits for common post-stroke conditions such as spasticity, balance disorders, and gait abnormalities that are difficult to achieve with land-based therapy.

Therapeutic Benefits of the Aquatic Environment for Stroke Patients

1. Spasticity Relief

Warm water (35–37°C) reduces the sensitivity of muscle spindles and decreases hyperactive tendon reflexes, effectively alleviating the upper and lower limb spasticity commonly seen after stroke. Multiple studies have shown significant improvements in Modified Ashworth Scale scores following aquatic therapy.

2. A Safe Environment for Gait Training

When walking in water, buoyancy reduces body weight and water resistance slows the speed of falls, allowing patients to practice weight shifting and gait adjustments in a relatively safe environment, thereby establishing neuromuscular patterns for walking on land.

3. Multisensory Stimulation for Balance Training

The instability of the water surface continuously challenges the vestibular and proprioceptive systems, providing rich sensory training that yields better improvements in balance disorders than some static land-based exercises.

4. Assistance with Fine Motor Control of the Upper Limbs

The viscosity of water slows movement speed, making it easier for patients to perceive movement feedback when practicing gripping and stretching with the affected arm in water, which helps reinforce neuroplasticity.

Current Status of Aquatic Physical Therapy in Taiwanese Hospitals

National Health Insurance (NHI) Coverage:

Currently, Taiwan’s NHI has limited coverage for aquatic physical therapy. Inpatient rehabilitation during the acute post-stroke phase may be partially covered, while outpatient aquatic therapy is mostly self-paid (approximately NT$800–2,000 per session). Patients may apply for partial subsidies through a disability handbook or a major illness/injury certificate.

Indications and Contraindications for Post-Stroke Aquatic Therapy

Post-stroke conditions suitable for aquatic therapy:

• Entering the stable phase 3–6 months after onset (not suitable during the acute phase)
• Mild to moderate hemiplegia with basic standing ability
• Those with aquaphobia must first undergo psychological adjustment on land
• No open wounds, urinary catheters, or pressure sores

Contraindications:

• Fever or acute infection
• Severe cardiopulmonary insufficiency
• Uncontrolled history of epilepsy
• Severe incontinence (fecal incontinence)
• Severe swallowing disorders (risk of drowning)

Typical Training Content in Aquatic Stroke Rehabilitation

Therapists design individualized programs based on the patient’s degree of hemiplegia. Common content includes:

• Aquatic standing training: Holding the pool wall with the unaffected hand while practicing weight bearing on the affected lower limb
• Aquatic walking: Walking forward, backward, and sideways, gradually reducing support
• Aquatic half-squats: Improving lower limb strength and bilateral coordination
• Aquatic upper limb exercises: Pushing water boards and practicing grasping objects in water with the affected arm
• Halliwick aquatic therapy: An internationally recognized aquatic neurorehabilitation method; some Taiwanese therapists have obtained certification

Practical Recommendations

1. Aquatic therapy for stroke patients must be supervised throughout by a therapist qualified in aquatic physical therapy; never attempt it on your own.
2. Family accompaniment can enhance the patient’s sense of security, and some hospitals allow family members to assist at poolside.
3. Adequate hydration is essential after aquatic therapy, as the diuretic effect of water pressure may cause dehydration.
4. It is recommended to alternate aquatic therapy with land-based physical therapy (e.g., aquatic on Monday, Wednesday, Friday; land-based on Tuesday, Thursday) for optimal synergistic effects.
5. Record the Fugl-Meyer assessment or walking speed (10-meter walk test) after each session to track recovery progress.

Conclusion

Aquatic physical therapy in Taiwan’s stroke rehabilitation field is gradually evolving from a “supplementary option” into a “core treatment module.” The physical properties of water provide stroke patients with a safe and effective environment for functional training. With the increasingly well-equipped hydrotherapy facilities and therapist training at Taiwanese medical centers, more and more stroke patients are regaining confidence and hope in their mobility through the water.
