I can see some wisdom in strengthening the foot to prevent PF but don't see how adding stress will heal an already injured foot. That goes against everything I know about how the body heals. You wouldn't apply that same logic to a sprained ankle, torn ligament or muscle or broken bone. Instead you immobilize them and protect them so they can heal and you don't keep reinjuring in the process..
Actually... depending on the injury, they may start using it again within a few days. Atrophy, scar tissue, and lack of oxygen all contribute to the damage. The best sports physiologists are/have moved to getting it moving and using sooner rather than later. A sprained ankle? If nothing torn usually with 3 days they start exercising it. Torn muscles within 2-3 days they will start actually doing lifts (light, but lifting). The sooner you get oxygenated blood to the injury and movement, the less scar tissue and atrophy set in.
As a general thing if there aren't torn ligaments and tendons (and sometimes if there are)- once over the initial hump and swelling starts to go down, I'm starting to move, strengthen, and work it loose. A couple months ago we had a person with a serious tear of the left pec and two broken ribs. Conventional thought would be 6-8 weeks before any use. Within 7 days he was benching light weight, high reps. Inside of two weeks he was at about 80%. By one month he was lifting normal again.
The one one and only time I got PF was from using supportive insoles for the first time during a month long rucking course. It lasted for months, but within two weeks of going completely barefoot and rehab I could run again. After a couplemonths it went away completely.
