Multiple Sclerosis (MS) presents numerous physical challenges that can significantly impact daily life. From limiting independence to decreasing physical activity levels, the neurodegenerative disease often leads to a decline in overall well-being. However, emerging research offers a promising solution: aquatic exercise.

Aquatic exercise provides a unique environment that can help individuals with MS improve their function and fitness in an accommodating setting. By harnessing the properties of water, this form of exercise reduces stress on joints, enhances balance, and facilitates a wider range of motion. A recent study investigated the effects of aquatic exercise on gait and strength outcomes in individuals with MS, revealing remarkable benefits.

This article dives into the findings of this groundbreaking research, exploring how aquatic exercise can improve muscle strength, gait patterns, and overall quality of life for individuals with MS. Discover how water-based workouts can unlock new levels of mobility and well-being.

The Science Behind Aquatic Exercise and MS

The study, conducted at California State University Northridge, employed a randomized controlled intervention design. Twenty participants with MS were divided into two groups: an aquatic intervention group and a control group. The aquatic intervention group engaged in 50-minute aquatic exercise sessions twice a week for 10 weeks, while the control group continued their daily activities.

Each aquatic session included a warm-up, gait and strength training, and a cool-down. Researchers assessed spatiotemporal and kinematic gait outcomes using a 3-D motion analysis system (VICON, Oxford, UK, 2010) and measured isometric strength of knee flexion and extension with a computerized dynamometer (Biodex Medical System Inc, Shirley, NY, 2012).

  • Increased Muscle Strength: The aquatic group showed a significant 32.60% increase in muscle strength in the quadriceps.
  • Improved Stride Length: Participants experienced a 14.03% increase in stride length.
  • Enhanced Walking Speed: Walking speed improved by 21.88%.
  • Greater Ankle Plantarflexion: Peak ankle plantarflexion increased by 71.62%.

Recent Evidence on Aquatic Therapy

A May 29, 2026 review describes aquatic therapy as a promising rehabilitation strategy for people with multiple sclerosis, with potential physical and psychological benefits linked to the properties of water. A December 1, 2025 controlled-trial study set out to compare an aquatic therapy program with conventional physiotherapy for fatigue and balance, while noting that controlled-trial evidence was limited. A 2024 systematic review and meta-analysis examined aquatic therapy’s effects on depression, fatigue, and balance. Separately, a review of 12 articles reported benefits across fatigue, depression, cognition, balance, motor function, physical independence, and functional capacity.

Evidence and Limits of Aquatic Rehabilitation

The 2020 systematic review with meta-analysis noted that the efficacy of aquatic physical therapy for people with multiple sclerosis was not clear in the scientific literature. A 2021 patient-reported outcomes article describes MS symptoms including mobility problems, fatigue, pain, cognitive impairment, and mood disturbances, and notes that disease-modifying therapies are first-line treatment. The MSAA publication was developed with CMSC, IOMSRT, and AEA to expand academic knowledge of aquatic exercise and MS. These sources underscore that aquatic exercise is discussed within a broader rehabilitation and treatment context, while the evidence base has included uncertainty.

These results indicate that aquatic exercise can effectively improve muscle strength in the knee extensors and gait patterns in individuals with MS. The findings suggest that aquatic exercise can facilitate the proper use of ankle plantarflexion for walking, an essential component of healthy gait.

Transform Your Life with Aquatic Exercise

The study's conclusions highlight the potential of aquatic exercise as a valuable intervention for individuals with MS. By improving muscle strength and gait patterns, aquatic exercise can enhance mobility, independence, and overall quality of life.

Measuring Gait Outcomes

A study on aquatic exercise and gait and strength in individuals with MS assessed spatiotemporal and kinematic gait outcomes using a three-dimensional motion analysis system. The system was VICON, Oxford, UK, 2010. This provides a concrete example of how gait changes in aquatic-exercise research were measured. The supplied source excerpt does not report the study’s outcome results.

Tracking Mobility and Broader Benefits

MSAA’s January 15, 2026 research summary says aquatic exercise may improve flexibility and range of motion, cardiovascular endurance, fatigue, muscle strength, mobility function—including gait and balance—quality of life, and psychological wellbeing. A March 2, 2023 systematic-review summary reports that aquatic exercise was associated with about 7.6% higher average walking speed over 500 m, suggesting potential for better household and community ambulation. A December 2, 2025 report describes a comparison of water exercise with standard physical therapy for fatigue and balance issues in MS. Together, these sources point to mobility and fatigue as continuing areas for evaluating aquatic exercise.

If you or someone you know is living with MS, consider incorporating aquatic exercise into your wellness routine. Consult with a healthcare professional or qualified aquatic therapist to develop a safe and effective program tailored to your specific needs and abilities.

Embrace the transformative power of aquatic exercise and unlock new levels of strength, mobility, and well-being. Take the first step towards a more active and fulfilling life.

What a randomized intervention can show

Randomised or controlled trial (level 3 of 8)

The randomized controlled design can compare changes over time between the aquatic group and a group continuing usual daily activities, but the reported quadriceps percentage is specifically a within-group change. These results describe the participants studied and do not establish how well the findings apply to other people with MS.[1]

Quadriceps strength before and after the program

  • 66.03 to 87.59In the aquatic group, the reported quadriceps-strength measure rose from 66.03 to 87.59; the paper describes this as a within-group increase, rather than a direct comparison of final scores between groups.[1]

How the gait and strength results fit together

The reported group-by-time interactions indicate that changes over time differed between the aquatic and control groups across several measured outcomes. That comparison adds context beyond the aquatic group’s own before-and-after gains, although it does not by itself explain which parts of the program contributed to the differences.[1]

The authors’ interpretation links the observed gait changes to ankle movement during walking and the strength result to knee extensors; these are specific measured functions, not evidence that every aspect of mobility changed.[1]
