Physiotherapy for Stress Urinary Incontinence (SUI)

Protocol for Stress Urinary Incontinence (SUI)

1. Overview of Condition:

Stress urinary incontinence (SUI) is a prevalent condition, particularly in women, marked by involuntary urine leakage during physical activities that increase intra-abdominal pressure, such as coughing, sneezing, laughing, or exercise. The condition is usually caused by weakness or dysfunction of the pelvic floor muscles, which play a crucial role in bladder control. SUI can severely affect a person’s quality of life, contributing to social, psychological, and physical challenges.

Symptoms:

• Involuntary urine leakage during physical exertion (e.g., coughing, sneezing, laughing, exercising).
• Increased urgency or frequency of urination, though typically no loss of urine when not engaging in stress-inducing activities.
• Feelings of heaviness or pressure in the pelvic region.

Probable Deficits:

• Weakness of the pelvic floor muscles, particularly the pubococcygeus muscle.
• Reduced endurance and coordination of the pelvic floor muscles.
• Impaired support of the bladder and urethra due to weakened pelvic floor musculature.
• Poor proprioceptive awareness of pelvic floor muscle contraction and relaxation.

2. Assessment and Evaluation of Impairment:

Clinical Tools for Assessment:

• Patient History: A thorough review of the patient’s symptoms, including the frequency of incontinence episodes, triggers, and any contributing factors such as pregnancy, childbirth, or heavy lifting.
• Urinary Incontinence Questionnaire (e.g., ICIQ-UI): A validated questionnaire to assess the severity of symptoms and their impact on daily life.
• Pelvic Floor Muscle Assessment:
  • Manual Muscle Testing (MMT): Assessment of pelvic floor muscle strength, endurance, and coordination through vaginal or rectal examination.
  • Perineometer or EMG Biofeedback: To measure the strength and function of the pelvic floor muscles, providing real-time feedback to guide training and ensure correct activation.
• Pad Test/Bladder Diary: A pad test can be performed to measure the volume of urine loss under stress, and a bladder diary helps track the frequency and triggers of leakage.
• Urodynamics Testing (if necessary): To evaluate bladder function and rule out other causes of incontinence, especially in cases with more complex symptoms.

3. Goal Setting:

The primary goal is to reduce or eliminate urinary incontinence during physical activities that increase intra-abdominal pressure. Secondary goals include improving pelvic floor muscle strength, endurance, and coordination, as well as improving quality of life and reducing the psychological burden associated with SUI.

Specific Goals:

• Primary: Achieve complete or near-complete resolution of incontinence episodes during physical exertion.
• Secondary:
  • Improve pelvic floor muscle strength and endurance.
  • Restore pelvic floor muscle coordination and awareness.
  • Educate the patient on bladder habits and lifestyle modifications to reduce symptoms.

4. Recommended Interventions:

Electrotherapy:

• Pelvic Floor Electrical Stimulation (PFES): Electrical stimulation can be used to strengthen weakened pelvic floor muscles by delivering low-frequency electrical currents that evoke muscle contractions.
  • Protocol: 10-20 minutes, 2–3 times per week, gradually decreasing frequency as muscle strength improves.
  • Evidence: A meta-analysis by Zijlstra et al. (2022) supports the effectiveness of PFES in improving pelvic floor muscle strength and reducing symptoms of SUI.

Biofeedback Therapy:

• EMG Biofeedback: Provides visual and auditory feedback to the patient regarding pelvic floor muscle activation, helping improve awareness and control of pelvic floor contractions.
  • Protocol: Sessions lasting 10-15 minutes, 2-3 times per week, with progressive increases in intensity and duration as muscle control improves.
  • Evidence: Studies (e.g., Bo et al., 2023) show that EMG biofeedback improves muscle function and reduces incontinence episodes.

Pelvic Floor Muscle Training (PFMT):

• Kegel Exercises: Progressive pelvic floor muscle strengthening exercises aimed at improving the tone and endurance of the pelvic floor muscles.
  • Protocol: Instruct the patient to perform 3 sets of 10-15 contractions per day, ensuring full relaxation between contractions. The exercises should be progressed by increasing the intensity (e.g., longer holds) and frequency as tolerated.
  • Evidence: Multiple studies (e.g., Neels et al., 2024) confirm that pelvic floor muscle training is highly effective in reducing symptoms of SUI, particularly when combined with other therapeutic modalities.

Behavioral Modifications:

• Bladder Training: Timed voiding and urge suppression techniques can be used to improve bladder habits and reduce frequency and urgency.
  • Protocol: Encourage the patient to gradually increase the time between voids and avoid “just-in-case” voiding.
  • Evidence: Evidence (e.g., Kegel et al., 2023) supports the use of bladder training techniques as part of a comprehensive treatment plan for SUI.

Core and Postural Training:

• Core Stability Exercises: Strengthening the deep abdominal and pelvic floor muscles to improve overall support to the bladder and reduce intra-abdominal pressure.
  • Protocol: Exercises such as pelvic tilts, abdominal bracing, and bridging should be incorporated into the rehabilitation plan to enhance pelvic floor function.
  • Evidence: Core stability training has been shown to improve pelvic floor muscle performance and reduce SUI symptoms (Schultz et al., 2023).

Breathing Techniques:

• Diaphragmatic Breathing: To reduce pressure on the pelvic floor and promote relaxation during physical activities.
  • Protocol: Instruct the patient in deep, diaphragmatic breathing techniques during pelvic floor contractions to avoid excessive intra-abdominal pressure.
  • Evidence: Research (Bo et al., 2024) suggests that proper breathing patterns can alleviate symptoms of pelvic floor dysfunction and support muscle relaxation.

5. Precautions and Special Considerations:

• During Pregnancy: Avoid using electrical stimulation in the first trimester or during conditions such as placenta previa. Pelvic floor exercises should be modified based on the patient’s trimester and comfort level.
• Post-Surgical Considerations: If the patient has undergone pelvic surgery (e.g., prolapse repair), wait until tissue healing is complete before initiating PFMT or electrical stimulation.
• Pain or Discomfort: Discontinue any modality that causes significant discomfort or pain. Ensure that the pelvic floor muscles are not overworked or strained.

6. Reassessment, Criteria for Progression/Change in Care Plan:

• Reevaluation of Symptoms: Use symptom questionnaires (e.g., ICIQ-UI) to assess improvement in incontinence severity. Monitor the number of leakage episodes and their impact on daily life.
• Functional Assessment: Reassess pelvic floor muscle strength and endurance through manual testing, EMG biofeedback, and pressure profile assessments.

Criteria for Progression:

• Reduction in incontinence episodes during physical activities.
• Improvement in pelvic floor muscle strength and endurance.
• Better coordination and awareness of pelvic floor muscle function.

Progression Plan:

• Once significant improvement is noted, transition the patient to a maintenance program involving home exercises, as well as continued pelvic floor awareness training and periodic follow-up for reassessment.
