OBJECTIVE: To investigate the reliability of isokinetic peak torque and work and
isometric peak torque measurements for knee flexion and extension in fibromyalgia
(FM) patients by determining the smallest real difference (SRD).
Test-retest reliability study.
Women with FM (N=37) aged between 34 and 74 years. INTERVENTIONS: Not applicable.
The participants performed isometric, concentric, and
eccentric tests of the knee. Unilateral maximal peak torque and average work were
measured for each direction (flexion, extension) and contraction (isometric,
concentric, eccentric) type. Relative reliability, absolute reliability, and SRD
were calculated. The 3 tests were repeated after an interval of 7 days. RESULTS:
With the exception of eccentric flexion, all peak torque measures had an
intraclass correlation coefficient (ICC) of > 0.90, and all work measures had an
ICC of > 0.85. The SRD ranged between 21% and 37% for all peak torque measures
and between 40% and 73% for all work measures. CONCLUSIONS: Isokinetic
dynamometry provides reliable measurement of peak torque and work for isometric,
concentric, and eccentric knee flexion and extension in patients with FM. The
present study has generated novel SRD data, which will assist physicians,
therapists, and clinicians in interpreting posttreatment changes in patients with
FM.
