Clinimetric properties of a walking scale in peripheral neuropathy.

Difficulty in walking is seen in many people with peripheral neuropathies, but walking ability is not comprehensively measured by commonly used outcome measures. The clinimetric properties of the 12-Item Multiple Sclerosis Walking Scale (MSWS-12, renamed the Walk-12) were investigated in 65 patients with peripheral neuropathies. Owing to its excellent internal consistency and reliability, and strong correlation with measures of physical and social function (r>0.8), the Walk-12 is recommended for measuring walking ability in peripheral neuropathies.
