The Role of Physiotherapy in Managing Pes Planus (Flatfoot)

Introduction

Pes planus, commonly referred to as flatfoot, is a condition characterized by the partial or complete collapse of the arch of the foot. This condition may be congenital (present at birth) or acquired due to factors such as injury, aging, or overuse. While flatfoot is often asymptomatic, it can lead to pain, discomfort, and biomechanical dysfunction in severe cases. Physiotherapy plays a critical role in managing pes planus, aiming to alleviate symptoms, improve function, and prevent complications.

Understanding Pes Planus

Flatfoot can be classified into two main categories:

1. Flexible Flatfoot: The arch is visible when the foot is off the ground but flattens when weight is applied.
2. Rigid Flatfoot: The arch remains flat regardless of weight-bearing or position.

Causes of Pes Planus

• Congenital: A natural variation in the structure of the foot, often present from birth.
• Acquired: Arising later in life due to factors such as:
• Posterior tibial tendon dysfunction (PTTD)
• Trauma or fractures
• Rheumatoid arthritis
• Obesity or excessive weight gain
• Overuse or repetitive stress injuries

Symptoms and Complications

Symptoms:

• Pain or fatigue in the feet, particularly in the arch or heel area
• Swelling along the inside of the ankle
• Difficulty walking or standing for prolonged periods
• Altered gait patterns

Complications:

• Plantar fasciitis
• Tendonitis
• Knee, hip, or lower back pain due to altered biomechanics
• Increased risk of injury

Physiotherapy’s Role in Managing Pes Planus

Physiotherapy aims to:

1. Relieve pain and discomfort
2. Restore and enhance foot function
3. Prevent further complications
4. Improve overall mobility and quality of life

1. Assessment

The initial step in physiotherapy is a thorough assessment, including:

• Postural and gait analysis
• Range of motion (ROM) testing
• Muscle strength testing, particularly of the posterior tibial and intrinsic foot muscles
• Functional movement assessments to identify compensatory patterns

2. Exercise-Based Interventions

Strengthening Exercises

• Intrinsic Foot Muscle Training:
• Toe curls using a towel

• Picking up small objects with toes

• Short foot exercises to activate the intrinsic muscles

• Posterior Tibial Muscle Strengthening:
• Resisted inversion exercises using a resistance band
• Heel raises to strengthen the calf and tibialis posterior

Stretching Exercises

• Calf Stretching: Tight calf muscles (gastrocnemius and soleus) can exacerbate flatfoot by increasing tension on the plantar fascia.
• Plantar Fascia Stretching: Gentle stretches to maintain flexibility and reduce pain.

Balance and Proprioception Training

Flatfoot can impair proprioception, leading to instability. Balance exercises such as single leg stands, wobble board exercises, and dynamic stability drills help enhance stability.

3. Manual Therapy

Physiotherapists may use hands-on techniques such as joint mobilization, soft tissue massage, and myofascial release to:

• Improve joint alignment and mobility
• Reduce pain and muscle tightness
• Facilitate proper arch support

4. Orthotic Management

Although physiotherapists do not prescribe orthotics, they often work alongside podiatrists to ensure proper fitting and use. Custom orthotics or over-the-counter insoles can:

• Provide additional arch support
• Redistribute weight to reduce pressure on specific areas of the foot
• Improve overall alignment and biomechanics

5. Gait Training

Physiotherapists can guide patients in correcting gait abnormalities caused by flatfoot. Proper foot placement, stride length, and weight distribution are emphasized to optimize efficiency and reduce compensatory patterns.

6. Education and Lifestyle Modifications

• Footwear: Physiotherapists advise wearing supportive footwear with proper arch support and cushioning to reduce stress on the feet.
• Weight Management: Maintaining a healthy weight can decrease the load on the arches and reduce symptoms.
• Activity Modification: High-impact activities may need to be substituted with low-impact exercises like swimming or cycling.

Special Considerations for Children

Pediatric flatfoot often resolves naturally as the arches develop. However, if pain or functional issues persist, physiotherapy interventions like those for adults are employed, with an emphasis on playful and engaging exercises.

Outcomes and Prognosis

With consistent physiotherapy, many individuals experience significant improvement in symptoms and function. While physiotherapy cannot restore the natural arch in most cases, it can effectively reduce pain, enhance mobility, and prevent further complications.

Physiotherapy is an integral part of managing pes planus, particularly for individuals experiencing pain or functional limitations. A combination of strengthening, stretching, manual therapy, and education empowers patients to manage their condition effectively. Early intervention and adherence to a tailored physiotherapy plan can lead to optimal outcomes, ensuring improved quality of life and mobility.
