Immediate and Short-Term Effects of In-Shoe Heel-Lift Orthoses on Clinical and Biomechanical Outcomes in Patients With Insertional Achilles Tendinopathy.

Background: Physical therapists frequently employ heel lifts as an intervention to reduce Achilles tendon pain and restore function. Purpose: To determine the short-term effect of heel lifts on clinical and gait outcomes in participants with insertional Achilles tendinopathy (IAT). Study Design: Case series; Level of evidence, 4. Methods: Participants with IAT underwent eligibility screening and completed assessments at baseline and 2 weeks later. Primary outcomes included symptom severity (Victoria Institute of Sports Assessment-Achilles [VISA-A]), gait analysis with the 10-m walk-test at 2 speeds (normal and fast), and pain during walking. Pain and gait analysis were assessed under 3 conditions: before fitting 20-mm heel lifts, immediately after heel-lift fitting, and after 2 weeks of wearing heel lifts. Ultrasound images and measurements at the Achilles insertion were obtained from prone and standing positions (with and without heel lifts). Spatiotemporal gait parameters and tibial tilt angles were evaluated at normal speed using inertia measurement units during the 3 study conditions. Differences between the conditions were analyzed using paired t test or analysis of variance. Results: Overall, 20 participants (12 female, 13 with bilateral IAT; mean age, 51 ± 9.3 years; mean body mass index 31.6 ± 6.8 kg/m2) completed all assessments. Symptom severity (VISA-A) of the more symptomatic side significantly improved at 2 weeks (60 ± 20.6) compared with baseline (52.2 ± 20.4; P < .01). Pain during gait (Numeric Pain Rating Scale) was significantly reduced immediately after heel-lift fitting (0.7 ± 2.0) when compared with baseline (2.2 ± 2.7, P = .043). Spatiotemporal gait parameters and tibial tilt angle before and after using heel lifts at normal walking speed were not significantly different; however, gait speed, stride length, and tibial tilt angle on both sides increased significantly immediately after using heel lifts and were maintained after 2 weeks of wear. Conclusion: Using heel lifts not only improved symptom severity after 2 weeks but also immediately reduced pain during gait and had a positive impact on gait pattern and speed.

A Cross-Sectional Study Investigating Lumbar Proprioception Impairments in Individuals with Type 2 Diabetes Mellitus: Correlations with Glycated Hemoglobin Levels.

Impaired proprioception is a recognized complication in individuals with type 2 diabetes mellitus (T2DM), contributing to balance deficits and increased risk of falls. However, limited research has focused on lumbar proprioception in this population. This study aimed to investigate lumbar proprioception in individuals with T2DM, as well as healthy individuals. Additionally, this study aimed to examine the correlation between lumbar proprioception and glycated hemoglobin (HbA1c) levels, which is a marker of long-term glycemic control in T2DM. A cross-sectional study was conducted, comparing lumbar joint reposition errors (JRE) between a T2DM group (n = 85) and a healthy group (n = 85). Lumbar JRE was assessed in flexion, extension, lateral bending left, and lateral bending right using a dual inclinometer device. HbA1c levels were measured as an indicator of glycemic control. Significant differences in lumbar JRE were found between the T2DM and healthy groups, with individuals with T2DM exhibiting larger JRE values, indicating impaired lumbar proprioception (p < 0.001). The correlation analysis revealed significant positive associations between HbA1c levels and lumbar JRE. Higher HbA1c levels were correlated with greater joint JRE in flexion (r = 0.49, p < 0.001), extension (r = 0.51, p < 0.001), left lateral bending (r = 0.45, p < 0.001), and right lateral bending (r = 0.48, p < 0.001) in the T2DM group. This study provides evidence of impaired lumbar proprioception in individuals with T2DM, as evidenced by larger lumbar JRE compared to the healthy group.

Differences at the Achilles Insertion Between Adults with Insertional and Midportion Achilles Tendinopathy as Observed Using Ultrasound.

Background: The purpose of this study was to determine structural and pathological differences of Achilles tendon insertion between insertional Achilles tendinopathy (IAT) and midportion Achilles tendinopathy (MidAT) in both injured and uninjured sides. METHODS: Patients (n=34; 58.8% male) with unilateral Achilles tendinopathy (50% with IAT; 50% with MidAT) were recruited. Median age 52 years and Victorian Institute of Sport Assessment - Achilles (VISA-A) score mean 59, and 17 (12 male) had MidAT, median(range) age of 58(48)years, and VISA-A score mean(SD) 59.1(19.7). Ultrasound imaging was used to evaluate structural measurements at the insertion (insertional length, bone-to-insertion length, and tendon insertion angle), tendon length (calcaneus to soleus), tendon thickness at the calcaneal edge, and the presence of pathological changes (boney deformity and/or calcification). A 2×2 mixed Analysis of Variance (group by side) was used to compare IAT and MidAT groups and injured and uninjured sides. RESULTS: Tendon thickness at the calcaneus on the injured side was significantly greater than the uninjured side in the IAT group but not in the MidAT group (P=.001). VISA-A score was 59.9(18.7) in IAT group and 59.1(19.7) for MidAT group (P=.909). There were no significant group-by-side interactions for structural measurements at insertion site. CONCLUSION: Calcaneal edge tendon thickness was the only significant structural difference observed between involved and uninvolved sides in IAT, although this was not found in in MidAT.

The Impact of the Degree of Kinesiophobia on Recovery in Patients With Achilles Tendinopathy.

OBJECTIVE: Kinesiophobia has been proposed to influence recovery in individuals with Achilles tendinopathy. However, whether there are differences in outcomes in individuals with different levels of kinesiophobia is unknown. The purpose of this study was to compare the characteristics of patients at baseline and recovery over time in individuals with Achilles tendinopathy and various levels of kinesiophobia. METHODS: This study was a secondary analysis of a prospective observational cohort study of 59 individuals with Achilles tendinopathy. The participants were divided into 3 groups on the basis of scores on the Tampa Scale for Kinesiophobia (TSK) (those with low TSK scores [≤33; low TSK group], those with medium TSK scores [34-41; medium TSK group], and those with high TSK scores [≥42; high TSK group]). All participants were evaluated with self-reported outcomes, clinical evaluation, tendon morphology, viscoelastic property measurements, and a calf muscle endurance test at baseline, 6 months, and 12 months. No treatment was provided throughout the study period. RESULTS: There were 16 participants (8 women) in the low TSK group (age = 51.9 [SD = 15.3] years, body mass index [BMI] = 24.3 [22.3-25.4]), 28 participants (13 women) in the medium TSK group (age = 52.7 [SD = 15.2] years, BMI = 26.4 [22.5-30.8]), and 15 participants (8 women) in the high TSK group (age = 61.1 [SD = 11.1] years, BMI = 28.1 [25.2-33.6]). Among the groups at baseline, the high TSK group had significantly greater BMI and symptom severity and lower quality of life. All groups showed significant improvement over time for all outcomes except tendon viscoelastic properties and tendon thickening when there was an adjustment for baseline BMI. The high and medium TSK groups saw decreases in kinesiophobia at 6 months, but there was no change for the low TSK group. CONCLUSION: Despite the high TSK group having the highest BMI and the worse symptom severity and quality of life at baseline, members of this group showed improvements in all of the outcome domains similar to those of the other groups over 12 months. IMPACT: Evaluating the degree of kinesiophobia in individuals with Achilles tendinopathy might be of benefit for understanding how they are affected by the injury. However, the degree of kinesiophobia at baseline does not seem to affect recovery; this finding could be due to the patients receiving education about the injury and expectations of recovery.

FREQUENCY OF PATHOLOGY ON DIAGNOSTIC ULTRASOUND AND RELATIONSHIP TO PATIENT DEMOGRAPHICS IN INDIVIDUALS WITH INSERTIONAL ACHILLES TENDINOPATHY.

BACKGROUND: Insertional tendinopathy is likely caused by different pathologies. This variation could account for the recalcitrant nature of this condition to treatment. Ultrasound imaging may assist in identifying underlying pathology to inform patient management. HYPOTHESIS/PURPOSE: The primary purpose of this study was to quantify the presence of underlying pathology using ultrasound in individuals with a clinical diagnosis of insertional Achilles tendinopathy. Secondarily, we sought to examine the relationship of abnormal ultrasound findings to age and body mass index (BMI). STUDY DESIGN: Cross-sectional study. METHODS: Fifty-six individuals with insertional tendinopathy were included in this study. B-mode ultrasound imaging was used to descriptively and quantitatively describe tendon pathology. RESULTS: A greater proportion of bone defect (p<0.001), intratendinous calcifications (p = 0.01) and midportion tendinosis (p<0.001) were observed on the injured side compared to the uninjured side. Higher BMI was associated with presence of bone deformity, intratendinous calcifications and distal tendinosis (p = 0.001-0.04); adding age did not significantly improve the regression model. CONCLUSION: Patients with insertional tendinopathy present with multiple underlying pathologies. This may account for variable response to treatment. It may be helpful to include imaging to better identify underlying pathology when trying to determine an appropriate treatment strategy. LEVEL OF EVIDENCE: Level 3.
