“…The sample size for the original trial was calculated to detect differences between groups on kinematic gait variables with a minimum of 10 participants per group (25). This same sample size also provided 83% power (α = 0.05) to detect a difference of at least 13 single-leg heel raise repetitions (SD = 10) between groups, which was the most conservative result from a prior study on the single-leg heel raise test (2). A total of 20 participants with MS were enrolled in an effort to increase power for the correlation analyses.…”

“…Impaired skeletal muscle performance, as defined by decreased strength and/or endurance, is highly prevalent in people with multiple sclerosis (MS) (1,2) and contributes to mobility limitations (3). Ankle plantarflexion muscle performance may be especially important for mobility in people with MS as it has been shown to be a key contributor to walking performance (4)(5)(6)(7)(8).…”

“…One such measure is the heel raise test, which measures the total number of single-leg heel raises that a patient can complete in a continuous bout at a consistent cadence (23,24). Previous studies have reported that in people with MS the heel raise test was reliable for assessing both the weaker and stronger limbs (2), valid at differentiating between people with MS and a healthy control group (2), and a key contributor to walking performance (7,8). While ankle plantarflexion strength measured by electromechanical dynamometry has also been shown to correlate with walking performance (3,4), to our knowledge, the heel raise test and ankle plantarflexion strength testing have not been previously compared within the same study.…”

Background: The single-leg heel raise test is a common clinical assessment; however, little is known about its validity in people with multiple sclerosis (MS). This study investigated the validity of the single-leg heel raise test in a group of people with MS and a healthy control group (CTL).Materials and Methods: Twenty-one people with MS (49 ± 12 years, Expanded Disability Status Scale 1.5–5.5) and 10 healthy controls (48 ± 12 years) performed the single-leg heel raise test, ankle plantarflexion isometric strength assessment using electromechanical dynamometry, and mobility measures (Timed 25-Foot Walk, 2-Min Walk Test, Functional Stair Test).Results: Convergent validity between the heel raise test and strength was moderate for participants with MS completing <20 heel raises (r = 0.63, p = 0.001) but weak for the entire sample (r = 0.30, p = 0.020). Compared to the average CTL group values, the heel raise test differentiated between groups on the MS groups' weaker (p < 0.001) and stronger (p = 0.003) limbs, while strength only differentiated between groups on the weaker limb (p = 0.010). Considering the weaker and strong limbs from the MS group and the CTL group average values, the mobility measures had moderate-to-strong correlations with the heel raise test on the weaker MS limb + CTL (r = 0.71–0.78) and stronger MS limb + CTL (r = 0.62–0.70), and weak-to-moderate correlations with strength on the weaker MS limb + CTL (r = 0.49–0.58, p = 0.001–0.007).Discussion: In people with MS, the single-leg heel raise test may be clinically useful as it identified impaired muscle performance and differentiated muscle performance from a healthy control group and, together with the control group, correlated with functional mobility.

“…The ankle plantar flexors are a critical driver of gait for people with MS, particularly during push-off in the terminal stance period of the gait cycle [ 34 ]. Deficits in ankle plantarflexion muscle function (strength and endurance) are common in people with MS [ 35 ] and are associated with worse walking performance (speed and endurance) [ 36 ]. Therefore, improving ankle plantarflexion muscle function in people with MS is a common goal of clinical rehabilitation intervention [ 37 ].…”

“…3 Of modifiable impairments, muscle weakness contributes strongly to gait in people with MS, is highly prevalent, and can be widespread through the lower extremities and trunk. [8][9][10] Strength training is considered one of the basic elements of exercise and physical activity for people with MS. 11 Several systematic reviews have established the effectiveness of strength training to improve strength, however, the effects on gait and mobility are not as consistent. 4,10,[12][13][14][15][16] There are several commonly proposed explanations for these inconsistent results, including rigor of design, heterogeneity of interventions and outcomes, and characteristics of enrolled samples (e.g., disability level, MS type, and other contributors besides weakness).…”

Practice Points• In studies that implemented strength training and measured gait outcomes, this review found a trend for significant improvement in strength outcomes, however not for gait performance as measured by speed and endurance.• This review found that studies including strength training for people with MS, either alone or in combination with other rehabilitation interventions, are typically prescribed in a manner consistent with current guidelines, and can improve strength. However, in order to improve gait, future studies might consider exploring higher intensities or frequencies.• This review found that strength training exercises most often focused on the knee and were performed on weight machines in a sitting position. This may be a reason strength training has not resulted in consistent improvements in gait, and future studies are needed that investigate muscle targets, positions, and modes of exercise that are functionally relevant to gait. www.ijmsc.org International Journal of MS Care PreprintO n l i n e F i r s t 3 Abstract Background: There are mixed reports on the effectiveness of strength training to improve gait
