Study Notes

Neuropathic Ulcers (NUs)

Commonly referred to as diabetic foot ulcers.
Affect 15-25% of patients with diabetes.
Develop due to neuropathy, high plantar pressures, decreased skin oxygenation, and diminished vascular perfusion.
60% of individuals with a NU will develop another within three years.
Leading cause of non-traumatic lower limb amputations.
50% of individuals who have an amputation will experience a second amputation within 3-5 years.

Risk Factors for NUs

Neuropathy.
Peripheral vascular disease.
Pre-ulcerative skin changes.
Hypertension.
Sex and age.
Smoking.
Charcot joint.
Diabetes, impaired visual acuity, chronic renal disease, and uncontrolled hyperglycemia.

Wagner Classification System

Assesses ulcer depth and the presence of osteomyelitis or gangrene using a scale.
Scoring:
- 0: No open lesions, but may have deformity or cellulitis.
- 1: Superficial ulcer.
- 2: Deep ulcer extending to tendon, bone, or capsule.
- 3: Deep ulcer with abscess, osteomyelitis, or joint sepsis.
- 4: Localized gangrene.
- 5: Gangrene on the entire foot.

Physical Therapy Tests and Measures

Semmes-Weinstein Monofilament Test: Considered the gold standard for assessing protective sensation in the lower extremities.
Vibration Sensation Exam: Utilizes a tuning fork for individuals at high risk for neuropathic ulcers.

Physical Therapy Interventions

Patient-Related Instructions:
- Education is crucial to increase patient control over the condition.
- Includes role, foot inspections, and specific coordination instructions.
- Additional precautions are necessary.
Procedural Interventions:
- Goal is to offload the ulcer and provide safe and effective gait.
- Non-weight bearing (NWB) using a scooter is recommended.
- Partial weight bearing (PWB) with an assistive device may be acceptable.
- Wheelchair may be necessary for some patients.

Therapeutic Exercise

Recommendations for Individuals with Diabetes:
- Aerobic: 3-7 days/week, moderate to vigorous intensity, 150 minutes/week at moderate intensity, targeting large muscle groups.
- Resistance: 2 non-consecutive days/week, moderate to vigorous intensity, 8-10 exercises (1-3 sets/10-15 repetitions), using free weights or machines.
- Flexibility: 2-3 days/week, stretching to the point of tightness, holding static stretches for 10-30 seconds with 2-4 repetitions, incorporating static, dynamic, or proprioceptive neuromuscular facilitation (PNF) stretching techniques.
