“…Kalaska 31 suggested that the proprioceptive system may be better tuned to active muscular movements than to movements imposed passively by external forces. This finding is also consistent with the results of Laufer et al, 32 who found that decreased accuracy and greater directional biases when encoding the target location were achieved by passive rather than active movements. Moreover, whereas both active and passive values were affected by military exercise, the increase in JPS errors postexercise was higher for active than for passive values.…”

Context: The high incidence of lower limb injuries associated with physical exercises in military conscripts suggests that fatigue may be a risk factor for injuries. Researchers have hypothesized that lower limb injuries may be related to altered ankle and knee joint position sense (JPS) due to fatigue.Objective: To evaluate if military exercises could alter JPS and to examine the possible relation of JPS to future lower extremity injuries in military service.Design: Cohort study. Setting: Laboratory. Patients or Other Participants: A total of 50 male conscripts (age ¼ 21.4 6 2.3 years, height ¼ 174.5 6 6.4 cm, mass ¼ 73.1 6 6.3 kg) from a unique military base were recruited randomly.Main Outcome Measure(s): Participants performed 8 weeks of physical activities at the beginning of a military course. In the first part of the study, we instructed participants to recognize predetermined positions before and after military exercises so we could examine the effects of military exercise on JPS. The averages of the absolute error and the variable error of 3 trials were recorded. We collected data on the frequency of lower extremity injuries over 8 weeks. Next, the participants were divided into 2 groups: injured and uninjured. Separate 2 3 2 3 2 (group-by-time-by-joint) mixed-model analyses of variance were used to determine main effects and interactions of these factors for each JPS measure. In the second part of the study, we examined whether the effects of fatigue on JPS were related to the development of injury during an 8-week training program. We calculated Hedges effect sizes for JPS changes postexercise in each group and compared change scores between groups.Results: We found group-by-time interactions for all JPS variables (F range ¼ 2.86-4.05, P , .01). All participants showed increases in JPS errors postexercise (P , .01), but the injured group had greater changes for all the variables (P , .01).Conclusions: Military conscripts who sustained lower extremity injuries during an 8-week military exercise program had greater loss of JPS acuity than conscripts who did not sustain injuries. The changes in JPS found after 1 bout of exercise may have predictive ability for future musculoskeletal injuries.Key Words: fatigue, proprioception, lower extremity, muscles Key PointsAfter an 8-week military exercise program, the loss of joint position sense (JPS) acuity was greater in injured than in uninjured conscripts. The JPS changes were greater in the ankle than in the knee joint. Greater JPS changes postexercise might increase the risk of subsequent musculoskeletal injury during basic training.

“…Given previous research that suggests people are better at localizing their limb after it has been actively moved than when it has been passively positioned (Coslett et al 2008;Laufer et al 2001;Paillard and Brouchon 1968), we thought that the sense of hand position would be less susceptible to proprioceptive recalibration in the active hand placement experiments. The improved ability to localize a limb after an active movement has been attributed to changes in the firing of sensory receptors (Al-Falahe et al 1990;Burke et al 1978a,b;Gandevia et al 1992;Hullinger and Vallbo 1979;Rymar and D'Almedia 1980) and central representations (Prud'homme and Kalaska 1994), including centrally generated neuronal events (i.e., an efference; Gandevia 1987; McCloskey 1980).…”

OBJECTIVE:This study aimed to evaluate the influence of acute muscle stretching on manual function. METHODS:The sample consisted of 10 untrained men in a randomized, four test session cross-over experimental design. Each session was composed of only one of two protocols: a) control, or b) single series of passive static stretching; followed by either Minnesota Hand dexterity test or hand grip strength test with eletromyographical recording of reaction time. For data comparison, the Student T-test with significance level of p ≤ 0.05 was used. RESULTS: Manual dexterity increased after stretching for both placing and turning tests, with no changes in hand grip strength or reaction time. CONCLUSION:The results show that a 30 second static stretch of the hand decreases time to complete the Minnesota Hand Dexterity test without affecting handgrip strength or hand reaction time; thus it improves manual dexterity of young untrained men. KEYWORDS:Muscle stretching, motor skills, reaction time. ■ INTRODUCTIONStretching exercises are often prescribed for persons with reduced motor skills or range of motion. Several reports describe this exercise technique as a necessary activity for better performance in daily life activities.1-4 However, muscle stretching seems to evoke neural and mechanical adaptations that reduce strength, reaction time and body balance; 3,5-7 it also affects the responsiveness of relevant afferent structures, such as muscle spindles 8 and Golgi tendon organs, 9 which are important structures in the regulation of motor commands.Manual dexterity, handgrip strength and reaction time are important components to assess hand function, which relate to better quality of daily life 1,10 and recreational activities; 2,11 they also act as indicators of cognitive and exercise performance 12,13 and are determinant factors in the ability to manipulate objects.14 Additionally, manual dexterity and handgrip strength are closely interdependent, in an interaction known as strength-dexterity trade-off. 15Manual dexterity is also related to the central nervous system, since the cortex receives information from several proprioceptors 8,16 to modulate manual motor tasks increasing movement efficiency.14,17-19 Hence, if muscle stretching does interfere with these factors it could alter the ability to manipulate objects. Because several sports, such as boxing, 20 handball, 21 basketball, 22 and many non-sporting activities such as musical performance 23 require agility and manual dexterity, the assessment of hand function is essential for the development of training techniques and functional rehabilitation of hand movements. However, there is a lack of knowledge about the effect of static stretching on manual dexterity. We hypothesized that muscle stretching would interfere with these factors and consequently alter hand dexterity.The purpose of this study was to understand the effect of static stretching on manual dexterity, providing evidence for health professionals seeking to prescribe stretching exercises safely and effi...
