Custom-made hinged knee braces with extension support can improve dynamic balance.

ABSTRACT: Background/Objective: We investigated whether custom-made hinged knee braces can facilitate knee extensor and flexor strength and influence functional performance as compared with other knee braces.

Methods

We enrolled 28 healthy young participants with no history of physical activity or brace use. The participants executed functional performance tests under the following 5 conditions: 1) without a knee brace, 2) wearing a knee sleeve, 3) wearing a hinged knee brace without assistance, 4) wearing a knee brace with extension support (KBE), and 5) wearing a knee brace with flexion support (KBF). The KBE and KBF were custom-made hinged knee braces equipped with rubber tubes. The functional performance tests performed assessed maximal isokinetic strength, single-leg jumping height/distance, anterior and posterior reach distance on a single leg, and dynamic balance ability.

Results

The benefit of the custom-made hinged knee brace was observed only during the anterior reach distance on a single leg. The KBE allowed a significantly greater single-leg anterior reach distance when compared to that in the no brace condition. There was a significant relationship between the improvement in the single leg anterior reach distance with KBE and the changes in isokinetic knee extension with KBE compared to the no brace condition. With regard to other parameters, there were no differences compared with the use of other knee braces and thus no apparent benefit.

Conclusion

Our findings suggest that using a KBE enhances performance during dynamic balance activity in individuals who benefit from improved knee extension strength.

Project description:CONTEXT::Knee osteoarthritis affects 9.3 million adults over age 45 years in the United States. There is significant disability associated with this condition. Given the potential complications and the significant cost to the health care system with the dramatic increase in total knee arthroplasties performed for this condition, assessment of the efficacy of nonoperative modalities, such as offloading knee braces, is essential as part of optimizing nonoperative treatment for this condition. OBJECTIVE::To determine the effectiveness of valgus offloader braces in improving clinical outcomes for patients with medial compartment knee osteoarthritis. DATA SOURCES::Three databases (PubMed, MEDLINE, and EMBASE) were searched from database inception through July 28, 2017. STUDY SELECTION::Studies reporting outcomes of valgus offloader knee braces in the treatment of medial compartment knee osteoarthritis were included. STUDY DESIGN::Systematic review. LEVEL OF EVIDENCE::Level 4. DATA EXTRACTION::Data pertaining to demographics, descriptive statistics, and clinical outcomes were extracted from the included studies. The methodological quality of included studies was evaluated. RESULTS::A total of 31 studies were included, with a total of 619 patients. The majority of studies reported improved pain outcomes using valgus offloader braces. However, variable results were reported as to whether valgus offloader braces significantly improved functional outcomes and stiffness. Offloader bracing was more effective at reducing pain when compared with neutral braces or neoprene sleeves. CONCLUSION::Valgus offloader bracing is an effective treatment for improving pain secondary to medial compartment knee osteoarthritis. The literature remains unclear on the effectiveness of valgus offloader braces with regard to functional outcomes and stiffness. Larger prospective randomized trials with consistent outcome assessment tools and consideration of patient compliance would be beneficial to more accurately determine treatment effects of valgus offloader bracing.

Project description:Objective:Ready-made spectacles have been suggested as a less resource-intensive treatment for the millions of people living with uncorrected refractive error (URE) in low-income environments. In spite of this interest, there have been no published economic evaluations examining the cost-effectiveness of ready-made spectacles. This study aims to determine the relative cost-effectiveness of offering ready-made spectacles (RMS) relative to no intervention as well as the relative cost-effectiveness of custom-made spectacles (CS) relative to RMS to treat URE. Methods and analysis:The relative cost-effectiveness of RMS relative to CS and no intervention was tested through a cost-effectiveness analysis from the health service provider perspective conducted alongside a double-masked randomised controlled trial in an urban hospital in Delhi, India. Participants were adults aged 18-45 years with ?1?dioptre (D) of URE. Results:There was no significant difference between the effectiveness of the CS and RMS interventions in improving visual acuity, but the CS was over four times the price of the RMS per patient (204 INR (US$2.42) and 792 INR (US$11.22)). The cost per unit improvement in logarithm of the minimum angle of resolution (logMAR) relative to baseline with the RMS intervention was 407 INR (US$4.35). Existing estimates of utility resulting from improvements in visual acuity result in incremental cost per quality-adjusted life years gained of between 212 INR and 1137 INR (US$0.44-US$23.74) depending on the source of the utility estimate and assumed expected life of the spectacles. Conclusion:RMS represent a significantly cost-effective option for spectacle provision in low-resource settings. The RMS programme was substantially cheaper than an equivalent CS intervention while being effective in improving visual acuity for the majority of adults with refractive error in this setting. These findings provide further support for including RMS in programmes to address URE. Trial registration number:NCT00657670, Results.
