The immediate effects of tension of Counterforce forearm Brace on neuromuscular performance of wrist extensor muscles in subjects with lateral humeral epicondylosis
'Journal of Orthopaedic & Sports Physical Therapy (JOSPT)', 2004Co-Authors: Ng Gyf, H. L. ChanAbstract:Study Design: Within-subject repeated-measures study. Objectives: To examine the immediate effects of Counterforce forearm Brace on isokinetic strength, stretch reflex, passive stretching pain threshold of the wrist extensors, and proprioception of the wrist in subjects with lateral humeral epicondylosis for different strap tensions of a forearm Brace. Background: Counterforce forearm bracing has been used for treating lateral humeral epicondylosis, but the effect of Brace tension has not been well reported. Methods and Measures: Fifteen subjects diagnosed with lateral humeral epicondylosis on their dominant arm were tested under 4 randomized conditions: (1) no Brace, (2) Brace with minimal tension, (3) Brace with 25-N tension, and (4) Brace with 50-N tension. The tests included isokinetic wrist extensors strength, passive stretching force in wrist flexion to elicit pain in the wrist extensors, wrist proprioception, and stretch reflex latency of the extensor carpi ulnaris. A repeated-measures MANOVA was used to analyze the data and significant results were further analyzed with post hoc linear contrasts (α = .05). Results: Among the 4 conditions, significant differences were found in wrist proprioception (P = .032) and pain threshold to passive stretching of the wrist extensors (P = .05), but were not found in wrist extension isokinetic strength and stretch reflex latency of the extensor carpi ulnaris. Conclusion: A forearm Counterforce Brace, as applied in this study, affects wrist joint proprioception and increases the pain threshold to passive stretching of the wrist extensors in subjects with lateral humeral epicondylosis, but it has no effect on wrist extensor strength and stretch reflex latency of the extensor carpi ulnaris.Department of Rehabilitation Sciences2003-2004 > Academic research: refereed > Publication in refereed journa

Effect of Counterforce forearm bracing on wrist extensor muscles performance.
American Journal of Physical Medicine & Rehabilitation, 2003Co-Authors: H. L. ChanAbstract:OBJECTIVES We examined (1) the effect of a Counterforce forearm Brace on isokinetic strength, stretch reflex, passive stretching, and proprioception of the forearm muscles in healthy subjects and (2) the effect of different strap tensions of the Brace on the above variables. DESIGN The dominant hand of 15 healthy subjects were tested under four randomized conditions: (1) no Brace, (2) Brace with minimal tension, (3) Brace with 2.5 kg force tension, and (4) Brace with 5 kg force tension. The tests included isokinetic wrist extensors strength, passive stretching to the wrist extensors until onset of pain, joint proprioception, and reflex latency of forearm extensor muscles. A repeated measures multivariate analysis of variance test was used to analyze the data, and significant results were further analyzed with post hoc linear contrasts with alpha at 0.0083. RESULTS There was no difference in isokinetic strength, proprioception, and stretch reflex latency among the four conditions. For passive stretching, there was a significant difference (P = 0.001) in that using a Brace produced a higher pain threshold than without a Brace. CONCLUSION A forearm Counterforce Brace has no effect on strength, proprioception, and stretch reflex latency, but it increases the pain threshold.

Effectiveness of high-intensity laser therapy and splinting in lateral epicondylitis; a prospective, randomized, controlled study
Lasers in Medical Science, 2015Co-Authors: Umit Dundar, Utku Turkmen, Hasan Toktas, Alper Murat Ulasli, Ozlem SolakAbstract:Lateral epicondylitis (LE) is a common disorder that causes pain on the outside of the elbow, as well as pain and weakness during gripping. In this prospective, randomized, controlled, assessor-blinded trial, we planned to investigate the effects of high-intensity laser therapy (HILT) in patients with LE and to compare these results with those of a Brace and placebo HILT. Patients were randomly assigned to three treatment groups. The first group was treated with HILT. The second group (sham therapy group) received placebo HILT, while the third group (Brace group) used the lateral Counterforce Brace for LE. The patients were assessed for grip strength, pain, disability, and quality of life. Outcome measurements and ultrasonographic examination of the patients were performed before treatment (week 0) and after treatment (after 4 and 12 weeks). HILT and Brace groups showed significant improvements for most evaluation parameters (pain scores, grip strength, disability scores, and several subparts of the short-form 36 health survey (physical function, role limitations due to physical functioning, bodily pain, general health, and vitality)) after treatment (after 4 and 12 weeks). However, the improvements in evaluation parameters of the patients with LE in HILT and Brace groups were not reflected to ultrasonographic findings. Furthermore, comparison of the percentage changes of the parameters after treatment relative to pretreatment values did not show a significant difference between HILT and Brace groups. We conclude that HILT and splinting are effective physical therapy modalities for patients with LE in reducing pain and improving disability, quality of life, and grip strength.

Immediate Effects of 2 Types of Braces on Pain and Grip Strength in People With Lateral Epicondylalgia: A Randomized Controlled Trial
American Physical Therapy Association, 2014Co-Authors: Bisset Leanne, Offord SoniaAbstract:Study Design Repeated-measures, crossover, double-blinded randomized controlled trial. Objectives To compare the immediate effectiveness of 2 types of Counterforce Braces in improving pain-free grip strength, pressure pain threshold, and wrist angle during a gripping task in individuals with lateral epicondylalgia. Background Sports medicine management of lateral epicondylalgia often includes application of a Counterforce Brace, but the comparative effectiveness of different Braces is unclear. The most common Brace design consists of a single strap wrapped around the proximal forearm. A variation of this Brace is the use of an additional strap that wraps above the elbow, which aims to provide further unloading to the injured tissue. Methods Pain-free grip strength, pressure pain threshold, and wrist angle during a gripping task were measured on 34 participants with a clinical diagnosis of lateral epicondylalgia (mean ᠓D age, 47.8 ᠸ.5 years). Measurements were made without a Brace, as well as immediately before and after the application of 2 types of Counterforce Braces. Each condition was tested during a separate session, with a minimum of 48 hours between sessions. Analysis-of-variance models were used to test the differences within and between conditions. Results Pain-free grip strength (17.2 N; 95% confidence interval: 7.5, 26.8) and pressure pain threshold (42.2 kPa; 95% confidence interval: 16.5, 68.0) significantly improved on the affected side immediately following the intervention conditions as well as the control condition. There was no significant difference between Braces or the control condition for any outcome. Conclusion Both types of Counterforce Braces had an immediate positive effect in participants with lateral epicondylalgia, without differences between interventions and similar to a no-Brace control condition. Therefore, while the use of a Brace may be helpful in managing immediate symptoms related to lateral epicondylalgia, the choice of which Brace to use may be more a function of patient preference, comfort, and cost. Further research is required to investigate the comparative longer-term and clinical effects of the 2 Braces.Griffith Health, School of Rehabilitation SciencesFull Tex

The efficacy of a specific forearm Brace (Go-Strap) compared to a standard Counterforce Brace in participants with tennis elbow.
Australian Physiotherapy Association, 2011Co-Authors: Bisset Leanne, Offord Sonia, Collins N.Abstract:Physiotherapy management of tennis elbow typically incorporates a multimodal approach including application of a forearm Brace. Good quality evidence comparing different Braces in the management of tennis elbow is scarce. The aim of this study was to investigate if a novel forearm Brace (Go-Strap Brace, Thermoskin驠could improve pain-free grip, pressure pain threshold and wrist angle during a gripping task in people with tennis elbow compared with a standard Counterforce Brace and control condition. A repeated measures, crossover, double-blinded randomised control design was used. Thirty-five participants with a clinical diagnosis of tennis elbow (mean age 47.8 (SD 8.5) years) were measured before and after the application of a Go-Strap Brace, a Counterforce Brace and control condition in a randomised order, a minimum of 48 hours between sessions. There was a significant main effect for time, with both Braces significantly improving grip (Mean difference (95% CI): Go-Strap 22 N (8 to 36), Counterforce 22 N (9 to 35)) and pressure (Go-Strap 48 kPa (2 to 93), Counterforce 59 kPa (16 to 102)) pre- to post-application. There was no significant change with the control condition for any outcome. There was no significant difference between treatments for any outcome (grip: p=0.363; pressure: p=0.480; wrist angle: p=0.203). In addition, wrist angle did not significantly change over time. These results indicate that while the application of a forearm Brace has an immediate positive effect on grip and pressure pain in participants with tennis elbow, the type of Brace does not preferentially influence these outcomes.Griffith Health, School of Rehabilitation SciencesNo Full Tex
