снизить нагрузку на конечность

[Qwerty7]

снизить нагрузку на конечность -

Как вы думаете, подойдет такой вариант:
the patient was advised to reduce load on the right leg?

Спасибо!

[Clea]

maybe sth like "...was advised to step with care on the right leg"

[Yegor]

Если слово "нагрузка" далее в этом тексте не встречается, можно попробовать: "...the patient was advised spare his (or her) right leg.

[Yegor]

Oops, я имел в виду "... the patient was advised TO spare his (or her) right leg. :)

[PERPETRATOR™]

not to (over)strain his right leg

[Анна Ф]

lessen the load on the leg

[Dmitry G]

А если это не нога?
Вар.:

[felog]

consider sth like:
cause/put less stress on the leg
