Balance Exercise

Background and Purpose Age-related changes in proprioception contribute to impairments in postural control and increased fall risk in older adults. The purpose of this randomized controlled trial was to examine the effects of balance exercises on proprioception. Subjects The participants were 36 older people and 24 younger people who were healthy. Methods Older participants were randomly assigned to a balance exercise group (n=17) or a falls prevention education group (n=19). Baseline, postintervention, and 8-week follow-up measurements of 3 proprioceptive measures (threshold to perception of passive movement, passive joint position sense, and velocity discrimination) were obtained at the ankle. For comparative purposes, younger participants underwent a one-time assessment of the 3 proprioceptive measures. Results Postintervention improvements in velocity discrimination were found in the balance exercise group when compared with values at baseline and in the falls prevention education group. Age-related differences found at baseline were reduced in the balance exercise group after intervention. Improvements were not maintained at the 8-week follow-up. Threshold to perception of passive movement and passive joint position sense did not change as a function of the exercise intervention. Discussion and Conclusion The results suggest that short-term improvements in velocity sense, but not movement and position sense, may be achieved following a balance exercise intervention.

Background and Purpose Age-related changes in the ability to adjust to alterations in sensory information contribute to impaired postural stability. The purpose of this randomized controlled trial was to investigate the effect of sensory-specific balance training on proprioceptive reintegration. Subjects The subjects of this study were 36 older participants who were healthy. Methods Participants were randomly assigned to a balance exercise group (n=17) or a falls prevention education group (n=19). The primary outcome measure was the center-of-pressure (COP) velocity change score. This score represented the difference between COP velocity over 45 seconds of quiet standing and each of six 5-second intervals following proprioceptive perturbation through vibration with or without a secondary cognitive task. Clinical outcome measures included the Fullerton Advanced Balance (FAB) Scale and the Activities-specific Balance Confidence (ABC) Scale. Assessments were conducted at baseline, postintervention, and at an 8-week follow-up. Results Following the exercise intervention, there was less destabilization within the first 5 seconds following vibration with or without a secondary task than there was at baseline or in the falls prevention education group. These training effects were not maintained at the 8-week follow-up. Postintervention improvements also were seen on the FAB Scale and were maintained at follow-up. No changes in ABC Scale scores were identified in the balance exercise group, but ABC Scale scores indicated reduced balance confidence in the falls prevention education group postintervention. Discussion and Conclusion The results of this study support short-term enhanced postural responses to proprioceptive reintegration following a sensory-specific balance exercise program.

Over recent years, a growing body of research has highlighted the neural plastic effects of spinal manipulation on the central nervous system. Recently, it has been shown that spinal manipulation improved outcomes, such as maximum voluntary force and limb joint position sense, reflecting improved sensorimotor integration and processing. This study aimed to further evaluate how spinal manipulation can alter neuromuscular activity. High density electromyography (HD sEMG) signals from the tibialis anterior were recorded and decomposed in order to study motor unit changes in 14 subjects following spinal manipulation or a passive movement control session in a crossover study design. Participants were asked to produce ankle dorsiflexion at two force levels, 5% and 10% of maximum voluntary contraction (MVC), following two different patterns of force production (“ramp” and “ramp and maintain”). A significant decrease in the conduction velocity (p = 0.01) was observed during the “ramp and maintain” condition at 5% MVC after spinal manipulation. A decrease in conduction velocity suggests that spinal manipulation alters motor unit recruitment patterns with an increased recruitment of lower threshold, lower twitch torque motor units.

Introduction and Aim:Osteoarthrosis is defined as degenerative condition of the synovial joints. Weak thigh muscle will cause impaired walking and balance and leads to risk of fall during activities of daily living. Use of MD and UD wobble board is hypothesized to improve balance and proprioception. So, pain, muscle power and proprioception are clinically important for balance control. Hence there is a need to study weight bearing exercise to hip abductor in various balance strategies to achieve muscle strength, joint position sense, balance, and activity of daily living.   Methodology: Knee osteoarthrosis subjects(n=219) were selected according to selection criteria andwere randomly allocated into 3 groups as multidirectional wobble board lateral step-up exercise group, unidirectional wobble board lateral step-up exercise group and control group. The pre-test KOOS pain, symptoms and ADL measurements were taken before the intervention and another measurement during the 2nd week of intervention and at the end of the intervention period during 4thweek post-test measurements were measured and statistically analysed.   Results:  At the end of 4th week control, UD and MD was found to be statistically significant with H=200.192 with p<0.001. KOOS symptoms between 3 groups was found to be statistically significant with H=200.288 and p <0.001. KOOS ADL values was found to be statistically significant between 3 groups with H=193.640 and p<0.001.   Conclusion: This study concludes that both unidirectional and multidirectional wobble board lateral step-up exercise showed improvement with KOOS pain, symptom and ADL scores compared to control group.

Background: Osteoarthritis (OA) is the most common form of arthritis. Pathologic process of osteoarthritis are changes of joint structures and surrounding structures. Injury on articular structure cause mechanical disturbance and reduce joint sensation. Proprioception has an important role in joint stabilization through sensorimotor system. Decrease of proprioception lead to decrease of functional ability on OA patients. Kinesio taping (KT) is one option of therapy in musculoskeletal injury.  Kinesio taping can reduce pain and inflammation, facilitate muscle activity and stimulate mechanoreceptor. This study aimed to evaluate the effect of KT application on proprioception in knee OA patients.Method: This study was an experimental pre-post study. We measured the proprioception function of eight participants with knee OA (mean age 59,3 ± 6,22 years) before and 30 minutes after KT application. Joint position sense (JPS) and time to detect passive movement (TTDPM) using Cybex Isokinetic Dynamometer were used as proprioception function measurement. Technique of KT used was superior and inferior Y with 25% stretch.Result: All of JPS and TTDPM from 8 participants, before and 30 minutes after KT application, both on affected and unaffected sides, showed no significant difference (p>0.05).Conclusion: Kinesio taping with superior and inferior Y 25% stretch did not improve JPS and TTDPM in knee OA patients.

Context:Cryotherapy, a common intervention used by clinicians, poses several benefits in managing acute injuries. However, cooling muscle tissue can interfere with muscular properties and the sensory-motor system.Objective:The aim of this study was to analyze the influence of cryotherapy with a crushed-ice pack on shoulder proprioception concerning joint position sense, force sense, the threshold for detecting passive movement, and maximal force production.Design:A randomized, double-blind controlled trial.Participants:48 healthy women aged 22.6 ± 0.4 y with a mean body mass index of 22.8 ±0.37 kg/m2 and a percentage of body fat of 15.4 ± 1.5%.Methods:In the experimental group, a crushed-ice pack was applied to the shoulder for 15 min, whereas participants in the control group applied a sandbag at skin temperature, also for 15 min. An isokinetic dynamometer was used to assess maximal voluntary contraction, force sense, joint position sense, and the threshold for detecting passive movement.Results:Paired sample t tests revealed that maximal voluntary isometric contraction decreased significantly after cryotherapy (P ≤ .001), or approximately 10% of the reduction found in both muscular groups assessed. Shoulder position sense (P < .001) and the threshold for detecting passive movement (P = .01 and P = .01 for lateral and medial shoulder rotator muscles, respectively) also suffered significant impairment. Nevertheless, no significant differences emerged in force sense at 20% and 50% of maximal force reproduction (P = .41 and P = .10 for lateral rotator muscles at 20% and 50%, respectively; and P = .20 and P = .09 for medial rotator muscles at 20% and 50%, respectively).Conclusion:Applying a crushed-ice pack to the shoulder for 15 min negatively affected muscle strength and impaired shoulder proprioception by decreasing joint position sense and the threshold for detecting passive movement.

Context Foam rolling (FR) is considered an effective postexercise modality for reducing delayed-onset muscle soreness and enhancing recovery of muscle function. However, the effects of FR on muscle and joint proprioception have not been investigated. Objective To examine the effects of FR on muscle and joint proprioception after an intense exercise protocol. Design Controlled laboratory study. Setting University-based laboratory. Patients or Other Participants A total of 80 healthy, physically active male students were randomly assigned to either the FR (n = 40; age = 22.8 ± 3.3 years, height = 176.4 ± 5.3 cm, mass = 74.2 ± 6.4 kg) or passive-recovery (PR; n = 40; age = 23.0 ± 3.2 years, height = 178.1 ± 5.5 cm, mass = 74.6 ± 6.2 kg) group. Intervention(s) Participants in both groups performed 4 sets of 25 repetitions of voluntary maximal eccentric contractions at 60°/s from 20° to 100° of knee flexion to induce exercise-induced muscle damage. The exercise was followed by either PR or 2 minutes of FR immediately (1 hour) and 24, 48, and 72 hours postexercise. Main Outcome Measure(s) Muscle soreness, pressure-pain threshold, quadriceps-muscle strength, joint position sense, isometric force sense, and threshold to detect passive movement at baseline and immediately, 24, 48, and 72 hours postexercise after FR. Results Foam rolling resulted in decreased muscle pain, increased pressure-pain threshold, improved joint position sense, attenuated force loss, and reduced threshold to detect passive movement compared with PR at 24 and 48 hours postexercise. Conclusions Foam rolling postexercise diminished delayed-onset muscle soreness and improved recovery of muscle strength and joint proprioception. These results suggested that FR enhanced recovery from exercise-induced damage.

Objective: In the present study we aimed to investigate the relationships between lower-limb joint proprioception and postural balance. Age-related differences in such relationships were also identified. Background: Impaired postural balance is reportedly one of the most common risk factors for fall accidents. Interventions have been proposed to improve postural balance by enhancing proprioceptive feedback. However, there is still no consensus on the optimal design for these interventions; therefore, there is a need to better reveal the contributions of lower-limb joint proprioception to postural balance. Method: Twenty-eight young and 28 older adults participated. Lower-limb joint proprioception was assessed by joint position sense errors measured at the ankle, knee, and hip of the dominant side, respectively. Postural balance was assessed by using center-of-pressure measures during bilateral static stance. Results: Ankle joint position sense error was positively correlated with root mean squared distance of the center of pressure in the anterior-posterior and medial-lateral directions in both young and older adults. Different from young adults, hip joint position sense error was positively correlated with root mean squared distance of the center of pressure in the anterior-posterior and medial-lateral directions in older adults only. Conclusion: Declined ankle and hip proprioception could be risk factors for falls in older adults. Age-related differences in the effects of hip proprioception suggests that hip proprioception is more important for maintaining balance in older adults. Ankle proprioception contributes the most to balance maintenance. Thus, ankle proprioception enhancement exercises should be considered in fall prevention interventions.
