PURPOSE: The purpose of this study was to determine the correlation between the Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC) and Knee Injury Osteoarthritis Outcomes scores (KOOS) and the degree of tibiofemoral cartilage loss on plain radiography and 3T magnetic resonance imaging (MRI). We hypothesize that these subjective outcome scores will have a significant correlation to quantitative joint space loss. METHODS: Data used in the preparation of this article were obtained from the osteoarthritis initiative (OAI) database (OAI public use data sets kMRI_QCart_Eckstein18 and kXR_QJSW_Duryea16). Four hundred and forty-five patients had WOMAC/KOOS scores, quantitative tibiofemoral joints space width on plain radiographs and quantitative tibiofemoral cartilage thickness and per cent full thickness cartilage loss on 3T MRI. Joint space width on plain radiographs was correlated to cartilage thickness on MRI, and WOMAC/KOOS scores were correlated to the degree of cartilage loss using Pearson correlation coefficients. RESULTS: There was a statistically significant correlation between medial and lateral compartment cartilage thickness on MRI and medial and lateral joint space width on plain radiography (r = 0.86, r = 0.80) (p < 0.001). KOOS knee pain score was significantly correlated to increasing per cent full thickness cartilage loss in the medial femoral compartment (r = 0.34) (p < 0.001). KOOS symptom score was significantly correlated to decreasing joint space width in the medial (r = 0.16) and lateral (r = 0.15) compartment and increasing per cent full thickness cartilage loss in the medial femoral compartment (r = 0.36) (p < 0.001). No WOMAC score was correlated to degree of joint space width, cartilage thickness or per cent full thickness cartilage loss (n.s). CONCLUSION: The WOMAC and KOOS scores are poor indicators of tibiofemoral cartilage loss, with only the KOOS symptom and knee pain score being weakly correlated. Osteoarthritis is a multifactorial process and the need to treat patients based off their symptoms and rely on radiographs as confirmatory modalities, and not diagnostic modalities, when talking about OA and medical intervention.

Study design:A 2 × 2 cross-over design.Objectives:To compare immediate effects of obstacle crossing training and conventional overground walking training on functional ability among independent ambulatory patients with spinal cord injury (SCI).Setting:A tertiary rehabilitation center, Thailand.Methods:Twenty independent ambulatory participants with SCI received a 1-day overground walking training and a 1-day obstacle crossing training program in a randomized cross-over design with a 2-day washout period. Immediately prior and after each training program, the functional ability of all participants was measured using the timed up and go test (TUGT), five times sit-to-stand test (FTSST) and 10-m walk test (10MWT).Results:The TUGT, FTSST and 10MWT data were significantly better after obstacle crossing training (P<0.001) but not after the overground walking training (P>0.05). The improvement following obstacle crossing training was also significantly different from that of the overground walking training (P<0.05).Conclusion:Obstacle crossing training immediately enhanced functional ability related to walking of ambulatory participants with SCI. However, a further longitudinal study using a randomized controlled trial is needed to support benefits of incorporation of obstacle crossing training into rehabilitation practice.Spinal Cord advance online publication, 22 January 2013; doi:10.1038/sc.2012.178.

PURPOSE: To assess methods for determination of exercise intensity, and to investigate practice variation with respect to the contents, volume and intensity of exercise training programs in Dutch cardiac rehabilitation (CR) centres. METHODS: A paper questionnaire was sent to all Dutch CR centres, consisting of 85 questions for patients with an acute coronary syndrome (ACS) or after coronary revascularisation (Group 1) and for patients with chronic heart failure (CHF, Group 2). RESULTS: CR professionals from 45 centres completed the questionnaires (58 %). Symptom-limited exercise testing was used to determine exercise capacity in 76 % and 64 % of the CR centres in group 1 and group 2, respectively; in these centres, a percentage of the maximum heart rate was the most frequently used exercise parameter (65 % and 56 %, respectively). All CR centres applied aerobic training and the majority applied strength training (64 % in group 1 and 92 % in group 2, respectively). There was a considerable variation in training intensity for both aerobic and strength training, as well as in training volume (1-20 h and 1-18 h respectively). CONCLUSION: Among Dutch CR centres, considerable variation exists in methods for determination of exercise intensity. In addition, there is no uniformity in training volume and intensity.
