BackgroundThe use of forearm crutches has been associated with pain and neuropraxia along the ulnar bone. Whilst anatomic grips have improved comfort of crutch walking, to date anatomic forearm cuffs have not been clinically evaluated. The aim of this clinical pilot study was to determine if the use of forearm crutches with anatomic cuffs reduces pain and increases comfort and function in long-term users of forearm crutches during a 4-week period.

MethodProspective study in ten patients suffering from end-stage osteoarthritis of the lower extremity. All participants were long-term users of conventional forearm crutches. Participants used forearm crutches with an anatomically shaped cuff for 4-weeks. General health was assessed using the SF-36, and the crutches were evaluated using a newly developed questionnaire focusing on symptoms along the forearm.

ResultsPain and paresthesia along the forearms decreased by 3.3 points 95% confidence interval difference CI: −5.0; −1.6, p = .004 and 3.5 points 95%CI: −5.1; −1.9, p = .002, respectively, after using the crutches with the new anatomic cuff for 4 weeks. Comfort and sense of security of crutch use increased by 3.0 points 95%CI: 1.3; 4.7, p = .007 and 2.4 points 95%CI: 0.7; 4.1, p = .024. Cross-correlation analysis revealed correlations among items in the same item category and no correlations between items of different item categories of the new questionnaires.

ConclusionAn anatomically shaped cuff increases comfort of forearm crutches. Further research should confirm long-term clinical improvement.

Trial registrationThis study was registered retrospectively in ISRCTN TRN: ISRCTN 11135150 on 14-02-2017.
