About this trial
The ENLIGHTEN PAD Trial will collect preliminary data to test whether daily 660 nm light treatment of the lower extremities immediately before home-based walking exercise sessions improves six-minute walk distance at 4-month follow-up, compared to sham light, in people with lower extremity peripheral artery disease (PAD).
Eligibility criteria
Qualifiers
An ABI <= 0.90 at baseline.
Vascular lab evidence of PAD (such as a toe brachial pressure <= 0.70 or an ankle brachial index less than or equal to 0.90), or angiographic evidence of PAD defined as at least 70% stenosis of an artery supplying the lower extremities.
An ABI of >0.90 and <= 1.00 who experience a 20% or greater drop in ABI in either leg after the heel-rise test.
Disqualifiers
Above- or below-knee amputation
Critical limb ischemia defined as an ABI <0.40 with symptoms of rest pain
Wheelchair confinement or requiring a walker to ambulate
Walking is limited by a symptom other than PAD
