Objective. To determine the tolerance and feasibility of aquatic-based power training for improving lower limb muscle power, impairments, and mobility in adults with symptomatic knee OA. Participants. Twenty-nine adults, age 50 years and over, with symptomatic knee OA (ACR clinical criteria) and mobility limitation (400-meter walk time slower than median for sex and decade) completed 45-minute aquatic power training sessions twice weekly for 6 weeks. Main Outcome Measurements. Prospective outcomes included tolerance of the program, as well as change in stair climb power, 400-meter walk time, overall and knee-specific pain, activities of daily living (ADL), quality of life (QOL), and lower limb function at 6- and 12-week follow-up. Results. The training intensity required modification for 9 of the 29 participants. Lower limb muscle power, ADL, QOL, and overall pain were improved immediately and 6 weeks following completion (all P < 0.05). However, 400-meter walk times, and lower limb function did not differ from baseline. Conclusions. A 6-week aquatic rehabilitation program appears to be well tolerated by adults with symptomatic knee OA with mobility limitations and may result in improved lower limb muscle power, symptoms, ADL, and QOL. However, this intervention may have insufficient specificity or intensity for improving physical function.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 October 2012.
All research outputs
#23,329,066
of 34,410,798 outputs
Outputs from Arthritis (20901984)
#55
of 80 outputs
Outputs of similar age
#158,134
of 224,309 outputs
Outputs of similar age from Arthritis (20901984)
#7
of 11 outputs
Altmetric has tracked 34,410,798 research outputs across all sources so far. This one is in the 30th percentile – i.e., 30% of other outputs scored the same or lower than it.
So far Altmetric has tracked 80 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 30.6. This one is in the 30th percentile – i.e., 30% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 224,309 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
