Association of Functional Mobility with Knee Proprioception in Knee Osteoarthritis Patients

Background: Knee osteoarthritis (OA), the most common arthritis type, causes pain and limits daily activities, especially in older adults. Age-related declines in proprioception and joint position sense increase joint load and impair neuromuscular control. This cross-sectional study examined the relationship between functional mobility and knee proprioception in OA patients, aiming to clarify their impact on treatment and mobility outcomes. Methods: A total of 33 participants were enrolled in this cross-sectional study based on the inclusion criteria. Functional mobility was assessed using three clinical measures: the Stair Climb Test (SCT), the 6-Minute Walk Test (6MWT), and the Five Times Sit to Stand Test (FTSST). Participants completed an initial trial of the 6MWT, and proprioception error was measured using a digital inclinometer. The FTSST and SCT were repeated three times after the first trial, with participants sitting high and holding for 5 seconds between each trial, returning to full knee extension before starting again. Results: Karl Pearson Correlation test demonstrated that there was a statistically significant moderately negative correlation was found between the FTSST and proprioception error (r=-0.444: p<0.05). There was a positive correlation between 6MWT and proprioception error (r=+0.132: p>0.05) and a low negative correlation between the SCT and proprioception errors (r=-0.018: p>0.05) but was not statistically significant. Conclusion: The study indicated that reduced physical mobility impairs proprioception, potentially contributing to or resulting from OA. It concluded that individuals with knee osteoarthritis had greater proprioception errors, with lower physical performance correlating to more pronounced proprioceptive deficits.

The Effects of an 8-Week Cognitive-Motor Training Program on Proprioception and Postural Control Under Single and Dual Task in Older Adults: A Randomized Clinical Trial.

The aim of this study was to assess the effects of an 8-week cognitive-motor training program on postural control and knee proprioception under single and dual task conditions. Design: Randomized clinical trial. Methods: The present study was registered with the ID number NCT04786132. A total of 20 healthy and physically active older adults (73.25 ± 5.98 years) volunteered to participate and were randomly assigned into an experimental and a control group (EG and CG). Postural control was measured with the Romberg test, with open (RBOE) and closed eyes (RBCE) and under unipodal dominant side (RUDL) conditions. Proprioception was assessed by measuring participants' ability to reposition their dominant knee at 45°. Finally, performance of the cognitive task was measured through a subscale of the Barcelona Test called "categorical evocation in associations". The EG and the CG completed 8-week training programs with two sessions, 30 min per week, of postural control and proprioception exercises. The EG additionally included music in each session. Results: The analysis using a mixed ANOVA model revealed no significant group × time interaction effects (p < 0.05) for any of the assessments. However, a significant main effect for the time factor was observed, with both the control and experimental groups showing improved outcomes in the post-intervention measurements. Specifically, significant results were found for RBOE (F (4,15) = 11.87, p < 0.001, η2p = 0.76), RBCE (F (4,15) = 11.62, p < 0.001, η2p = 0.75), and proprioception (F (1,18) = 11.53, p < 0.003, η2p = 0.39). Conclusions: The 8-week training program had a positive impact on the post-intervention results for motor control and proprioception, but not on the results of the cognitive task. There were no significant differences between the groups that carried out sessions with or without music.

Knee proprioception four months after anterior cruciate ligament reconstruction: impact of limb dominance, anterolateral procedure, and association with readiness to return to sport.

BackgroundKnee proprioception may be compromised after anterior cruciate ligament reconstruction (ACLR), but associated factors and impact remain unclear. This study evaluated knee proprioception 4 months after primary ACLR, compared with healthy controls, and explored the impacts of leg dominance, anterolateral procedures (AEAPs), and their association with psychological readiness to return to sports. MethodsThis prospective cohort study included 30 ACLR participants and 20 healthy controls. Isokinetic testing measured knee strength and proprioception, using passive joint position sense (JPS1: detection, JPS2: repositioning) and kinesthesia (threshold to detection of passive motion). At 8 months, ACLR participants completed the ACL-RSI scale to assess psychological readiness to return to sports. ResultsAt 4 months postoperative, kinesthesia was better in the operated limb than the non-operated limb (p= 0.008), but position sense did not differ significantly. There were no significant differences in kinesthesia or position sense between ACLR participants and controls. The operated limb had worse JPS2 if the ACLR was on the non-dominant side. Proprioception was unaffected by AEAPs, and only repositioning showed a moderate, non-significant correlation with ACL-RSI (r= -0.377). ConclusionAt 4 months post-ACLR, kinesthesia improved in the operated leg; dominance influenced position sense, highlighting the need for personalized rehabilitation.

The Effect and Long-term Prognosis of Different Suturing Methods for Meniscus Repair Under Knee Arthroscopy.

This study aims to evaluate the efficacy and long-term prognosis of all-inside and outside-in suturing methods for meniscus repair under knee arthroscopy. A retrospective analysis was conducted on 120 patients with meniscus injuries who underwent surgical treatment at Yuhuan People's Hospital, Department of Joint Surgery, from January 2019 to March 2021. Based on the suturing method, patients were assigned into two groups: Group A (64 cases, all-inside suturing) and Group B (56 cases, outside-in suturing). Surgical indicators and adverse events were recorded for both cohorts. The variances in proprioception before and after surgery, International Knee Documentation Committee (IKDC) scores, Lysholm scores, knee range of motion (ROM), and Visual Analogue Scale (VAS) pain scores were compared between the two groups. Group A had significantly shorter operative time, postoperative immobilization, and hospital stay compared to Group B (p < 0.05). The overall incidence of adverse events was 12.50% in Group A and 16.07% in Group B, with no significant difference between the groups (p > 0.05). There were no substantial differences in preoperative knee proprioception difference values, IKDC scores, Lysholm scores, VAS scores, and knee ROM between the two groups (p > 0.05). At three months postoperatively, Group A exhibited lower proprioception difference values at 15°C, 45°C, and 75°C angles compared to Group B (p < 0.05). Additionally, at three months and three years postoperatively, Group A showed higher IKDC scores, Lysholm scores, and ROM and lower VAS scores compared to Group B (p < 0.05). Compared to the outside-in suturing approach, the all-inside suturing method for treating meniscus damage is more effective. It attenuates operative time, postoperative immobilization time, and hospital stay, ameliorates knee proprioception, promotes knee function recovery, alleviates pain, and is safe and reliable.

Knee proprioception, muscle strength, and stability in Type 2 Diabetes Mellitus- A cross-sectional study

BackgroundThe burgeoning prevalence of Type 2 Diabetes Mellitus (T2DM) has been linked to a spectrum of health complications, including those affecting the musculoskeletal system. Knee proprioception, muscle strength, and stability are essential for maintaining functional mobility and preventing falls, yet their relationship with T2DM is not fully elucidated. ObjectivesThis study aimed to compare knee proprioception, muscle strength, and limits of stability (LOS) between individuals with T2DM and asymptomatic controls and to examine the moderating role of physical activity on these relationships. MethodsIn a cross-sectional design, 192 participants (96 with T2DM and 96 asymptomatic) underwent assessments for knee proprioception using a digital inclinometer, muscle strength via a handheld dynamometer, and LOS through dynamic posturography, graded as a percentage of maximum lean without losing balance. ResultsOur analysis revealed that individuals with T2DM demonstrated reduced knee muscle strength, with mean differences of 12.90 Nm (right) and 18.80 Nm (left) in 25° of flexion, and 25.78 Nm (right) and 26.36 Nm (left) in 40° of flexion, compared to asymptomatic controls. Proprioception errors were greater in the T2DM group (p < 0.001), with significant deficits noted in both knee 25° of flexion and 40° of flexion. Stability limits were also compromised, with the T2DM group displaying a decreased ability to maintain balance across all tested directions (p < 0.001). Physical activity emerged as a positive moderator, with higher activity levels correlating with improved muscle strength and stability. ConclusionT2DM significantly impairs musculoskeletal function, highlighting the need for integrated management strategies. The study underscores the importance of physical activity in mitigating T2DM-related musculoskeletal deterioration, suggesting that therapeutic interventions should include a focus on enhancing muscle strength and stability to improve the quality of life in this population.

Effects of Pilates Exercise Training on Static Balance and Lower Limbs Proprioception in Adult Females With and Without Flexible Flatfeet.

It is well known that flatfeet are associated with a higher incidence of lower limb injuries in different populations. Thus, we examine how Pilates exercise training affects static balance and ankle and knee proprioception in females with and without flexible flatfeet. Study Design. Case series; Level of evidence. This quasi-experimental study involves 91 healthy 18- to 25-year-old female university students. The Navicular Drop Test was used to diagnose flatfeet. Pilates included core strength, balance, and flexibility exercises for 16 weeks. Static balance was assessed using the sharpened Romberg test and ankle and knee joint proprioception were measured using joint position reproduction tests. The Wilcoxon test indicated within-group pre-post improvements in static balance, and ankle and knee joint proprioception in the Pilates and the healthy control group (P < .05). The between-group comparisons at post-test showed significant differences for joint position reproduction test of the dorsiflexion (P < .05, η2 = 0.10) and the plantarflexion (P < 0.05, η2 = 0.08) in favor of the healthy controls group. Joint proprioception of ankle and knee was positively correlated with increasing static balance in the healthy control group. The results showed that Pilates has the potential to improve static balance, and ankle and knee proprioception. However, it did not improve postural control and proprioception in individuals with flatfeet. Our findings advise combining Pilates with other interventions to develop flexible flatfeet in females. Level I.

Assessing the reliability of a digital inclinometer app for measuring hip, knee, and ankle proprioception.

Proprioception can be defined as the ability of an individual to detect motion and position of the various joints in their bodies. Current tools for measuring proprioception lack consensus on their accuracy and validity; they also each have their own limitations, and, furthermore, present barriers to use for clinicians. We propose a new and reliable method for evaluating hip, knee, and ankle proprioception by utilizing a digital inclinometer app to measure joint position sense. The digital inclinometer app recorded the active joint position sense error after each of five trials for the hip and knee joint and ten trials for the ankle joint. To quantify the reliability of the digital inclinometer app, single-measurement and average-measurement intra-class correlation coefficients (ICC) along with the associated 95% confidence intervals (95% CI) were calculated for each joint's position sense error across trials. Both the hip (ICC (2,k) = 0.849 (95% CI = [0.783-0.897])) and knee joint (ICC (2,k) = 0.837 (95% CI = [0.750-0.897])) were found to have moderate to good reliability when the middle three of five trials were analyzed. Unlike the hip and knee, moderate to good reliability for ankle proprioception (ICC (2,k) = 0.785 (95% CI = [0.539-0.893])) was only achieved with the middle eight of ten trials. The results of this study indicate that this digital inclinometer app is able to accurately record joint position sense at the hip, knee, and ankle when the appropriate number of trials are collected; thus, allowing this tool and methodology to be considered for use in both clinical and research environments to measure proprioception, and furthermore, quantify proprioceptive deficits.

How to Improve Meniscal Repair through Biological Augmentation: A Narrative Review.

Since the role of the menisci in knee stability, proprioception, and homeostasis has been well established, significant efforts have been made to repair meniscal tears, resulting in excellent clinical outcomes and a reduction in the progression of knee osteoarthritis (OA). However, varying failure rates have been reported, raising questions regarding the healing potential in cases of complex injuries, poorly vascularized and degenerated areas, and generally in the presence of unfavorable biological characteristics. Therefore, over the last few decades, different strategies have been described to increase the chances of meniscal healing. Biological augmentation of meniscal repair through various techniques represents a safe and effective strategy with proven clinical benefits. This approach could reduce the failure rate and expand the indications for meniscal repair. In the present study, we thoroughly reviewed the available evidence on meniscal repair surgery and summarized the main techniques that can be employed to enhance the biological healing potential of a meniscal lesion. Our aim was to provide an overview of the state of the art on meniscal repair and suggest the best techniques to reduce their failure rate.

The Effect of Total Knee Replacement on Dual-Task Gait Performance in Older Adults.

Total knee replacement (TKR) is a common solution for patients with advanced knee osteoarthritis (OA). Still, fall rates remain relatively high after surgery. TKR may alter pain and knee function, balance control, and proprioception. However, given the role of complex (dual-task) walking in fall prediction for older adults, it is unknown how TKR alters the attentional demand of walking in older adults. The goal of this study was to examine the effect of TKR on dual-task walking among older adults. Participants were evaluated 1month before surgery and 4.5months after surgery. Participants walked along an instrumented 7-meter path for 1minute with and without a cognitive task (serial-3 subtraction). Pain and knee function, knee proprioception, dynamic balance, and balance confidence, as well as dual-task costs (DTC) were compared before and after the surgery and factors associated with change in gait DTCs were assessed. Thirty-eight participants completed the study (age 72.6years, SD = 4.9; 11 men). A significant decrease in pain was found following TKR, with no change in balance, balance confidence, or proprioception. There were no differences in gait DTCs before and after the surgery. However, change in dynamic balance, specifically reactive postural control and dynamic gait, predicted changes in gait speed and stride time DTCs. The absence of an effect of TKR on gait DTCs can potentially underlie increased fall risk after TKR. Results from this study emphasize the significance of balance as a measure and focal point for rehabilitation after TKR. This study contributes to our understanding of the attentional cost of walking in people before and after TKR, as well as to factors associated with it. Results from this work can assist formulation of rehabilitation programs for people with knee OA.

The Effect of Sensorimotor Training on the Knee Proprioception and Functional Balance of Visually Impaired Women

Background and Aims Decreased vision is one of the sensory impairments that causes the sufferer to have difficulty in balancing and performing daily activities. The aim of this study was to investigate the effect of sensorimotor exercises on proprioception and balance in orderly women. Methods The present study is quasi-experimental and 30 women with visual impairment in the age range of 35 to 45 years were randomly divided into experimental and control groups. The experimental group performed sensory-motor exercises for 8 weeks and three sessions per week. Before and after the exercises, knee proprioception at 40 to 60 degrees with imaging method and functional balance was measured using the Y test. ANCOVA test was used to analyze the data at the significance level of (P=0.05). Results The results showed that after the intervention of sensorimotor exercises, the proprioception of the knee joint at an angle of 40 to 60 degrees and functional balance in the experimental group compared to the control group significantly improved (P=0.0001). Conclusion Strengthening the proprioception through motor-sensory exercises and improving motor-sensory input can increase balance in the elderly. Sensory-motor exercises in the closed motor chain strengthen the deep sensory feedback of the lower limb muscles and thus improve the balance and deep sense of the elderly.

Effects of Muscular Fatigue on Position Sense in Two Phases of the Menstrual Cycle.

It is generally accepted that local muscular fatigue can negatively affect position sense. Interestingly, it has been proposed that in women, position sense and neuromuscular coordination may be affected by fluctuations of estrogen and progesterone levels. The aim of this study was to examine the possible effect of localized muscle fatigue on knee joint position sense at two phases of the menses: follicular and luteal. Twenty physically active females aged 19-30 years, with normal menses, volunteered for this study. An isokinetic dynamometer was used to evaluate proprioception and perform the fatigue protocol of the knee extensors and flexors. Knee proprioception at rest and after fatigue at three knee target angles (30°, 45°, 60°) was measured. A three-way ANOVA analysis with repeated measures was performed. The results showed that the main effect of fatigue was significant, but no main effect of the menstrual cycle phase was found. Additionally, a main effect was found for the target angle (more flexed target knee joint angles were associated with larger angular error deviations). In conclusion, localized muscle fatigue can significantly reduce the accuracy of active knee joint repositioning in both the luteal and the follicular menstrual phases in young, physically active healthy women.

Cryotherapy effects on knee proprioception and quadriceps performance in healthy college students

BACKGROUND: Cryotherapy is widely utilized for therapeutic purposes, yet its specific effects on knee joint proprioception and quadriceps muscle performance in healthy individuals remain unclear. This study addresses this gap by examining the impact of a 20-minute cryotherapy session on knee joint proprioception and related muscle parameters in a cohort of healthy college students. OBJECTIVES: To investigate the effects of cryotherapy on knee joint proprioception and quadriceps muscle peak moment, work and power in healthy college male and female students. METHODS: Thirty-two healthy students, aged 19–23, underwent a 20-minute cryotherapy session using Cryogel packs applied to the anterior thigh and knee. An isokinetic dynamometer measured knee joint proprioception and quadriceps muscle parameters before, immediately after, 10-min, and 20-min post-cryotherapy. RESULTS: Proprioception values did not significantly differ between genders or post-tests (p&gt; 0.05). However, the female group exhibited significantly lower moment, power, and work values compared to males (p&lt; 0.05). No significant differences were observed within or between post-tests in moment, power, and work for both genders (p&gt; 0.05). CONCLUSIONS: A 20-minute cryotherapy application demonstrated no adverse effects on knee joint proprioception or quadriceps muscle metrics in healthy college students, supporting the safety of cryotherapy in this context.

The Effects of Post-Exercise Cold Water Immersion on Neuromuscular Control of Knee.

To date, most studies examined the effects of cold water immersion (CWI) on neuromuscular control following exercise solely on measuring proprioception, no study explores changes in the brain and muscles. The aim of this study was to investigate the effects of CWI following exercise on knee neuromuscular control capacity, and physiological and perceptual responses. In a crossover control design, fifteen participants performed an exhaustion exercise. Subsequently, they underwent a 10 min recovery intervention, either in the form of passively seated rest (CON) or CWI at 15 °C. The knee proprioception, oxygenated cerebral hemoglobin concentrations (Δ[HbO]), and muscle activation during the proprioception test, physiological and perceptual responses were measured. CWI did not have a significant effect on proprioception at the post-intervention but attenuated the reductions in Δ[HbO] in the primary sensory cortex and posterior parietal cortex (p < 0.05). The root mean square of vastus medialis was higher in the CWI compared to the CON. CWI effectively reduced core temperature and mean skin temperature and improved the rating of perceived exertion and thermal sensation. These results indicated that 10 min of CWI at 15 °C post-exercise had no negative effect on the neuromuscular control of the knee joint but could improve subjective perception and decrease body temperature.

Effect of Dynamic Balance Training on Physical Function and Proprioception in Individuals with Knee Osteoarthritis

Background: Osteoarthritis (OA) is a prevalent joint disorder affecting synovial joints, particularly the knee. It leads to degeneration of cartilage, causing pain and reduced physical function. Effective treatment strategies are essential for managing symptoms and improving quality of life. Objective: To determine the effect of dynamic balance training on physical function and proprioception in individuals with knee osteoarthritis. Methods: This quasi-experimental trial was conducted at Riphah International University Lahore, Aziz Medical Clinic, and Ali Hospital, Mughal Pura Lahore. A total of 48 patients with anterior knee pain were recruited and divided into two groups: one receiving dynamic balance training and the other receiving conventional physical therapy (control). Non-probability convenience sampling was used. Outcomes were measured using NPRS, a goniometer, the Community Balance and Mobility Scale (CB&amp;M), and the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Knee proprioception was assessed by joint position sense using a universal goniometer, with the average of three angles taken for the final reading. Data were analyzed using SPSS version 25. Results: Significant differences were observed in joint proprioception between weight-bearing (WB) and non-weight-bearing (NWB) procedures. The mean difference for WB was -3.07 compared to -2.18 for NWB, with a higher relative error in WB (p &lt; 0.05). Dynamic balance training resulted in greater reductions in NPRS scores and improvements in WOMAC scores compared to conventional physical therapy (p &lt; 0.05). Conclusion: Dynamic balance training was more effective than conventional physical therapy in improving physical function and proprioception in individuals with knee osteoarthritis.

Effect of core stability exercises on knee proprioception, function and quality of life in chronic total knee replacement patients

Background: Chronic osteoarthritis of knee joint leads to severe pain after weight bearing and prolonged activities .TKR is widely used as a successful and effective last-stage surgical treatment for relieving chronic knee pain and functional disability. This research aimed to study the effect of core stability exercises on knee proprioception, function and quality of life in chronic total knee replacement patients. Methods: Total 40 patients with chronic total knee replacement with age between 45-65 years were included. They were divided into two groups: Group-A (n=20) and Group-B (n=20). Both group received conventional treatment, in addition Group-B received core stability exercise. Patients were evaluated pre-intervention (0 week) and post-intervention (4 week) for proprioception (by universal goniometer), for function (LEFS) and for quality of life (SF-12). Statistical analysis was done using SPSS 20 version. Significance level was set at p&lt;0.05. Results: Wilcoxon signed rank test was applied for within group comparison. There was statistically significant difference in mean of proprioception, function and SF-12 PCS in both groups during four week intervention period. Mann Whitney U test was applied for between group comparison. Significant difference was found between Group-A and Group-B in mean difference of proprioception, function. Conclusions: The concluded that the core stability exercise along with conventional treatment is more effective for improving knee proprioception, function and quality of life than alone conventional treatment in chronic total knee replacement patients.

Cruciate-Retaining Total Knee Arthroplasty versus Unicompartmental Knee Arthroplasty in Medial Compartmental Osteoarthritis: A Propensity Score-Matched Analysis of Early Postoperative Recovery.

Cruciate-retaining (CR) total knee arthroplasty (TKA) may provide better physiological knee kinematics, proprioception, and quadricep recovery than posterior-stabilized (PS) TKA. Therefore, we hypothesized that CR TKA with multimodal pain control may provide comparable postoperative pain and recovery as unicompartmental knee arthroplasty (UKA). This study included patients with isolated medial compartment knee osteoarthritis who underwent CR TKA and UKA. TKA and UKA patients were propensity score-matched with age and body mass index (BMI) and compared using visual analog scales (VAS) for pain scores, total amount of morphine use (TMU), knee flexion angle, straight leg raise (SLR), independent ambulation, length of hospital stay (LOS), and costs during hospitalization. After propensity score matching, 46 patients were included in the TKA and UKA groups, respectively, with no differences in demographic data. VAS at 6-72 h and TMU at 48 h after surgery were comparable between the groups. The knee flexion angle in the UKA group was significantly higher at 24 h (60.0° vs 46.6°; p<0.001) and 48 h (76.9° vs 69.1°; p = 0.021) than that in the TKA group. The SLR in the UKA group was significantly higher than that in the TKA group at 24-72 h. The UKA group ambulated significantly earlier (1.56 vs 2.13 days; p<0.001), had shorter LOS (3.68 vs 4.28 days; p<0.004) and incurred 12.43% lower costs when compared to the TKA group. Patients who underwent CR TKA with multimodal pain management did not experience more postoperative pain or morphine use than those who underwent UKA. However, UKA patients seem to experienced faster recovery and shorter LOS than CR-TKA patients during the early postoperative course. Accordingly, UKA may be considered instead of TKA for patients who are good candidates for UKA and require expedited recovery.

The effect of 8-week combined balance and plyometric on the dynamic balance and agility of female adolescent taekwondo athletes.

To investigate the effect of combined balance and plyometric training (PT) on the agility and dynamic balance of adolescent taekwondo athletes. Thirty female adolescent taekwondo players volunteered to participate and were randomly assigned to the combined balance training and PT (CT; n = 15) and PT (n = 15) groups. The CT group performed balance training combined with PT 3 times a week for 6 weeks (40 minutes of plyometrics and 20 minutes of balance training) while the PT group performed only PT for the same period (3 sets × 8-12 reps for each exercise). Both groups received the same routine technical taekwondo training. Post-intervention assessments revealed that both groups significantly improved their dynamic posture stability index scores (DPSI; forward jump [F-DPSI] and lateral jump [L-DPSI]). However, participants in the CT group achieved notably superior outcomes in the F-DPSI and L-DPSI scores compared with those achieved by their PT counterparts. The center of pressure metrics exhibited improvements post-intervention, with scores of specific measures in the PT group surpassing those in the CT group. Additionally, the 5-0-5 test scores exhibited improvements post-intervention, with scores of specific measures in the PT group surpassing those in the CT group, and the TAST (Taekwondo Specific Agility Test) of the CT group and the PT changed significantly after the intervention. An 8-week regimen that integrates balance and plyometric training effectively augments knee function and proprioception in adolescent Taekwondo athletes. This study underscores the potential benefits of a combined training approach, providing coaches and athletes with valuable insights into Taekwondo training.

Immediate effects of kinesiology tape on quadriceps muscle peak torque and knee joint repositioning error in healthy males: Effects of different tensions and directions

BackgroundKnee joint injuries may result from compromised quadriceps muscle strength or diminished knee joint proprioception. The application of Kinesio tape (KT) on the quadriceps muscle from origin to insertion (OTI-KT) or insertion to origin (ITO-KT) could impact knee joint proprioception and quadriceps muscle strength. This study aims to assess the effects of different tensions and directions of KT application on active and passive knee joint repositioning errors (AJRE and PJRE) and peak concentric and eccentric peak torque (CPT and EPT) of the quadriceps muscles in healthy males. MethodTwenty-one healthy males participated in this repeated-measures study design. CPT, EPT, AJRE, and PJRE of the dominant limb were measured by a Biodex dynamometer before and after applying OTI-KT with 0%, 15%, and 40% extra tensions and ITO-KT with 0% tension. ResultsITO-KT demonstrated a significant reduction in AJRE (p < 0.05). Meanwhile, for OTI-KT, a statistically significant difference was observed in both AJRE and PJRE concerning time (F1,126 = 19.74, p < 0.05 for AJRE; F1,126 = 9.96, p < 0.05 for PJRE) and tension (F2,126 = 22.14, p < 0.05 for AJRE; F2,126 = 20.67, p < 0.05 for PJRE). ConclusionApplying KT, especially OTI KT with 40% and 15% extra tension, shows potential in enhancing knee proprioception without immediate impacts on quadriceps muscle torque. This suggests applications in sports performance and knee injury rehabilitation.

The effect of Wrestling+ warm-up program on balance and proprioception of adolescent wrestlers

Background: The present study aimed to investigate the effect of an 8-week Wrestling+ warm-up program on static-dynamic balance and proprioception of adolescent freestyle wrestlers. Methods: Twenty-four wrestlers (mean standard deviation for age: 15.8 0.8 years, and body mass index: 23.4 4.3 kg/ m2) participated in this study and were randomly divided into experimental (n=12) and control (n=12) groups. The experimental group performed three sessions/week of the Wrestling+ warm-up program, while the control group performed routine warm-up exercises during each session. The balance error scoring system (BESS) test for static balance, the Y-test for dynamic balance, and an active angle reconstruction test for knee and ankle joint proprioception were used. Analysis of covariance (ANCOVA) and pairedsamples t-test were used to compare the intergroup and intragroup differences, respectively, with a significance level set at p &lt; 0.05. Results: After the intervention, there were significant improvements in static balance (p &lt; 0.001) on both stable and unstable surfaces, and dynamic balance for the anterior (p = 0.047), posteromedial (p = 0.040), and posterolateral (p = 0.028) segments. Additionally, there was a significant reduction in proprioception errors during knee movements (p &lt; 0.001). Conclusion: The eight-week Wrestling+ warm-up program seems to have a positive effect on static and dynamic balance ability by improving knee joint proprioception in adolescent wrestlers. Hence, it is highly recommended to incorporate this specific warm-up program to enhance the performance of adolescent wrestlers and prevent injuries.
