Background: Physical activity (PA) provides various health benefits. Unfortunately, individuals with disabilities may experience health problems and greater obstacles to PA participation. Boxing exergame (EXG) based on virtual reality (VR) can be an alternative option to increase physical activity level because it is fun, relatively affordable and accessible. Punching in boxing requires complex movements, wherein the lower limbs are contributor for effective punches. An understanding of muscles activity is important to uncover the potential benefits of VR EXG.Aim: To evaluate the differences in upper limb muscles activity of the dominant side in standing compared to sitting position during punches.Material and methods: This was a cross-sectional study involving 15 healthy adult men. Surface electromyography examinations was performed on four upper limb muscles of the dominant side (upper trapezius, anterior deltoid, biceps, triceps) when delivering straight, hook and uppercut punches while playing VR EXG "Fitness Boxing" Nintendo Switch™ in standing and sitting position.Results: Fifteen healthy men (age 31.87±3.14 years old, BMI 23.77±2.47 kg.m-2) were participated in this study. No significant difference found in the percentage of maximum voluntary isometric contraction (%MVIC) values of the upper trapezius, anterior deltoid, biceps and triceps muscles of the dominant sides when the subjects delivered straight, hook and uppercut punches (p>0.05), except for upper trapezius muscle during uppercut punch in standing compared to sitting position (p=0.041).Conclusion: The VR EXG "Fitness Boxing" Nintendo Switch™ can be done in a standing or sitting position to get similar effect on the upper limb muscles.
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.
Background: Physical activity (PA) has been associated with multiple health benefits. However, the global population does not meet the PA recommendations. Virtual reality exergaming (VR EXG) can become an option to increase PA because it is fun, relatively easy to access and affordable through popular commercial devices.Aim: To investigate the immediate cardiovascular responses(blood pressure, heart rate), quantification of PA intensity(percentage of maximum heart rate (%HRmax), Borg’s rating of perceived exertion (RPE), and the level of enjoyment using visual analog scale (VAS) while playing VR EXG.Material and Methods: Fifteen healthy men (aged 31.87±3.14 years old, body mass index 23.77±2.47 kg/m2) undergone three“Fitness Boxing” Nintendo Switch™ playing modes in the same order: (1) single player-normal tempo, (2) single player-fast tempo and (3) versus. During playing, participant’s HR was monitored using Polar H10 heart rate sensor. Blood pressure was measured before and after playing. Borg’s RPE and VAS were collected after playing.Results: Our results showed significant heart rate and systolic blood pressure increase (p = 0.001) in all three playing conditions, whereas diastolic blood pressure was relatively constant (p > 0.05). The Borg’s RPE were in 12-13 range (moderate) and %HRmax range between 72- 81% (vigorous). The enjoyment level was found greatest in versus mode compared to other playing modes.Conclusion: VR EXG Nintendo Switch™ “Fitness Boxing” can elicit immediate cardiovascular responses and provides an enjoyable moderate to vigorous PA intensity in healthy male adults, and can be used to meet the weekly PA recommendations.
Objectives : To evaluate the effect of KinesioTaping on knee joint proprioception of patient withreconstructed anterior cruciate ligament.Methods: Randomized trial, cross-over study design, was done in Rehabilitation outpatient clinic, Soetomo General Hospital, Surabaya, on 9 isolated anterior cruciate ligament (ACL) patients, which hasunderwent ACL reconstruction procedure. Each patient will become control for themselves. Subjects were treated with standardized Kinesio Taping technique for anterior cruciate ligament injury in additionto standard rehabilitation program for anterior cruciate ligament reconstruction. Response to treatment was evaluated with two evaluations: 1) Joint position sense of the knee for predetermined angle (30°,45° and 60°) 2) Threshold to detect of passive knee motion on 90° moving into extension. Measurements were taken two times within 3 days of interval, with and without Kinesio Taping application. Errorof angular displacement of active angle reproduction (joint position sense) and threshold to detect of passive motion (TTDPM) were measured in three condition: before Kinesio Taping application, afterKinesio Taping application and without Kinesio Taping application. Results : Nine patients (mean age 20.33 ± 4.062 y) who had anterior cruciate ligament reconstruction were included for this study. There were no other knee ligament injuries.There were significant different in active angle reproduction (joint position sense) at 30° and 45° extension between affected and unaffected knee (p = .030 and p= .15 respectively). Kinesio Taping application showed significant effect in active angle reproduction at 30° of knee extension (p=0.028). There were no significant different in TTDPM between all condition. Conclusions: Kinesio Taping application improves active angle reproduction (joint position sense) at 30° of knee extension. There is no difference in joint position sense at 45° and 60° with Kinesio Tapingapplication. There is no difference in TTDPM in all condition.Keywords: Kinesio Taping, rehabilitation, knee joint proprioception, anterior cruciate ligament reconstruction.
