BackgroundExergaming is a promising new alternative to traditional modes of therapeutic exercise which may be preferable and more effective for people with Multiple Sclerosis (MS). Impaired balance is reported as one of the most disabling aspects of MS. The purposes of this study were to examine the effects of exergaming on: (1) postural sway, (2) gait, (3) technology acceptance and (4) flow experience in people with MS. Secondary outcomes were disability: 12‐item Multiple Sclerosis Walking Scale (MSWS-12) and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) questionnaire.MethodsFifty-six adults (mean age = 52 years, SD = 5.8; 38 women) with a clinical diagnosis of MS and able to walk 100 meters with or without use of a walking aid were included in this study and randomized into 3 groups. Group 1 received balance training using the Nintendo Wii Fit™ (exergaming) and Group 2 undertook traditional balance training (non-exergaming). Group 3 acted as a control group, receiving no intervention. Exergaming and traditional balance training groups received four weeks of twice weekly balance-orientated exercise. Postural sway was measured using a Kistler™ force platform. Spatiotemporal parameters of gait were measured using a GAITRite™ computerised walkway. Technology acceptance and flow experience were measured using the Unified Theory of Acceptance and Use of Technology and the Flow State Scale questionnaires, respectively.ResultsThere were significant improvements in bipedal postural sway in both intervention groups when compared to the control group; and no effects of either intervention on gait. There were no significant differences between the interventions in technology acceptance but on several dimensions of flow experience the Wii Fit™ was superior to traditional balance training. Both interventions showed improvements in disability compared to control.ConclusionsIn terms of the physical effects of exergaming, the Wii Fit™ is comparable to traditional balance training. These findings would support the use of the Wii Fit™ as an effective means of balance and gait training for people with MS, which is both accepted and intrinsically motivating to MS users.Trial registrationControlled Trials ISRCTN13924231.

The use of a valgus brace can effectively relieve the symptoms of unicompartmental osteoarthritis of the knee. This study provides an objective measurement of function by analysis of gait symmetry. This was measured in 30 patients on four separate occasions: immediately before and after initial fitting and then again at three months with the brace on and off. All patients reported immediate symptomatic improvement with less pain on walking. After fitting the brace, symmetry indices of stance and the swing phase of gait showed a consistent and immediate improvement at 0 and 3 months, respectively, of 3.92% (p = 0.030) and 3.40% (p = 0.025) in the stance phase and 11.78% (p = 0.020) and 9.58% (p = 0.005) in the swing phase. This was confirmed by a significant improvement at three months in the mean Hospital for Special Surgery (HSS) knee score from 69.9 to 82.0 (p < 0.001). Thus, wearing a valgus brace gives a significant and immediate improvement in the function of patients with unicompartmental osteoarthritis of the knee, as measured by analysis of gait symmetry.

Purpose. This study aimed to investigate whether textured insoles can improve gait in people with multiple sclerosis (MS). Relevance. Previous studies have shown that footwear, including textured insoles, may improve postural stability in healthy young and older adults (Palluel et al., 2008;Hatton et al., 2009;Hatton et al., 2011), and there is some evidence to show that footwear interventions may be beneficial for people with MS (Ramdharry et al., 2006;Kelleher et al., 2010). Participants. Forty-six people with MS (34 women), mean age (SD) 49 years (7), who reported that they were able to walk 100 m with or without resting with the use of one stick or crutch, participated in the study. Methods. Ethical approval was granted by the Local Research Ethics Committee. Participants were randomized to one of two textured insole groups: texture A (Algeos UK Ltd, Liverpool, UK), which was used in our previous studies (Hatton et al., 2009;Hatton et al., 2011), or texture B, a commercial insole (Crocs ™ , Den Haag, The Netherlands). Participants conducted baseline walking tests at their preferred speed along an instrumented walkway (GAITRite) in a laboratory setting, and temporal-spatial gait parameters were extracted. Participants then wore the insoles for two weeks and returned for repeat testing. Analysis. Paired t-tests were used to evaluate changes between baseline and follow-up. Results. Stride length increased between baseline and follow-up in both legs in group A (left p = 0.01, right p = 0.02) and group B (left p = 0.02, right p = 0.02). Velocity and cadence did not change significantly in either group. Discussion. This finding that textured insoles can produce improvements in stride length requires further investigation. It is consistent with research on foot orthoses in MS showing an improvement in balance after four weeks of wear (Ramdharry et al., 2006).
