Multimodal Prehabilitation to Improve Quality of Life and Functional Capacity in Peripheral Arterial Disease: A Case Series.
Miquel Coca-Martinez, Francesco Carli, Heather L Gill
PMID 34589689WHAT IT FOUND
Five patients with severe peripheral artery disease completed a 12-week multimodal program combining exercise, nutrition, and psychosocial support.
Walking distance and quality of life improved, and one wheelchair user regained function. This small series cannot prove the treatment works.
Key findings
01All five patients completed the 12-week multimodal prehabilitation program, which included supervised and home-based exercise, nutritional counseling, psychosocial support, and smoking cessation.
02Functional capacity improved, with the 6-minute walk test distance increasing by a median of 70 meters, and one patient who previously could not walk more than 50 meters without stopping regained the ability to walk without a wheelchair.
03Quality of life scores improved significantly on the Vascular Quality of Life Questionnaire and the Walking Impairment Questionnaire, although anxiety and depression scores did not change significantly.

What it does not show
The study included only five patients, which is too small to draw any conclusions about efficacy or generalizability. There was no control group, so it is impossible to know if the improvements were due to the intervention, natural history, or placebo effect. Home-based exercise adherence was self-reported and not objectively verified. The contributions of the different components (exercise, nutrition, psychosocial, smoking cessation) cannot be separated; any single element might have driven the outcomes.

The easy way to misread this
Do not interpret the improvements in walking distance and quality of life as proof that this multimodal program is effective. With only five participants and no control group, these results are anecdotal and cannot be generalized to other patients with peripheral artery disease.
