“…26 Intrinsic risk factors can include altered joint arthrokinematics, muscular imbalances, or muscular weakness in the upper extremity that may expose an individual to microtrauma of the involved tissues. 13 Grip strength weakness 11,12 and general weakness of the arm 1,10,31 have been reported in individuals with acute symptoms of lateral epicondylalgia. This is consistent with the finding that, during the tennis stroke, the musculoskeletal components of the scapula, shoulder, elbow, and wrist are essential links in the kinetic chain that transfers energy from the force-generating legs and trunk to the more rapidly moving segments of the wrist and hand.…”

Epidemiological reports suggest that up to 40% of tennis players experience lateral elbow pain at some time during their lifetime. 2,26Lateral epicondylalgia is one of the most common injuries in tennis players of all skill levels and can result in prolonged symptoms and reduced athletic performance. 15 Lateral epicondylalgia is characterized as a chronic overuse injury that is likely the result of multiple factors.26 However, high demands on the wrist extensor musculature from repeated muscular contractions in extreme positions of the upper extremity may contribute to the pathophysiology that leads to symptoms of lateral epicondylalgia. Both extrinsic and intrinsic factors contributing to injury may be present prior to the actual injury or onset of symptoms. Extrinsic risk factors can include errors in technique, environmental conditions, and equipment that alters the external forces applied to the upper extremity.26 Intrinsic risk factors can include altered joint arthrokinematics, muscular imbalances, or muscular weakness in the upper extremity that may expose an individual to microtrauma of the involved tissues. 13Grip strength weakness 11,12 and general weakness of the arm 1,10,31 have been reported in individuals with acute symptoms of lateral epicondylalgia. This is consistent with the finding that, during the tennis stroke, the musculoskeletal components of the scapula, shoulder, elbow, and wrist are essential links in the kinetic chain that transfers energy from the force-generating legs and trunk to the more rapidly moving segments of the wrist and hand.18 Therefore, it is impor-T T STUDY DESIGN: Descriptive, cross-sectional. T T OBJECTIVES:To compare static strength characteristics of the upper extremity musculature in female recreational tennis players with lateral epicondylalgia to those of nonsymptomatic tennis players and a control group of women who did not play tennis. T T BACKGROUND:There is a paucity of research describing the relationship between lateral epicondylalgia and strength characteristics of the upper extremity musculature, despite the functional relationship between the shoulder, elbow, and wrist. T T METHODS:Sixty-three women were recruited into 3 groups (n = 21 per group): symptomatic tennis players (STP) with lateral epicondylalgia, nonsymptomatic tennis players, and controls. Data collection was performed during a single session, during which the strength of selected muscle groups of the dominant upper extremity was measured using a combination of force transducers. Strength ratios of selected muscle groups were then calculated. T T RESULTS:The STP group reported median pain level of 3/10 on a numeric pain rating scale and a symptom duration of 16 weeks. The STP group had weaker lower trapezius strength (mean difference, -9.0 N; 95% confidence interval [CI]: -13.5, -4.4) and wrist extensor strength (-12.7 N; 95% CI: -24.4, -1.1), and a higher shoulder internal/external rotation strength ratio (0.19; 95% CI: 0.02, 0.35) and upper/lower trapezius strength ratio (1.32; 95% CI: 0.4...

“…Dorf et al showed that the measurement of extension grip strength is a useful objective tool to aid in the diagnosis of lateral epicondylitis. 2 In their study, the affected arm averaged 50% of the strength of the healthy arm in extension and 69% of the strength of the healthy arm in flexion. An 8% difference in grip strength between flexion and extension was found to be 83% accurate in distinguishing the affected from the unaffected extremities.…”

“…Such asymmetry has been attributed to intrinsic characteristics of the sports gesture and hampers the use of the contralateral limb as reference during a treatment. Moreover, a possible correlation between HS and lateral epicondylitis of the humerus has been proposed (11,12) . This injury presents a long recovery process (13) and, therefore, it is believed that the HS is very useful tool in the assessment of these athletes (11) .…”

“…The elbow position may influence on the HS, since the musculature which moves the wrist also passes through the elbow; therefore, alterations in the flexors tension/length ratio could alter the result of the test (11) . Additionally, it should be considered that in order to increase the HS is it necessary not only greater recruiting of flexor muscles, but also to increase the activity of the extensor muscles with the aim to keep the wrist in slight extension (18) .…”

It is important to assess the handgrip strength (HS) in competitive tennis players due to asymmetry between the dominant and contra lateral hands that players might develop. In order to assess HS, clinicians can use separate, already established protocols (from European Test of Physical Fitness Handbook [Eurofit] or American Society of Hand Therapists [ASHT]. The objective of this study was threefold: Firstly to compare the HS using the Eurofit and ASHT technique; secondly to compare HS between dominant/non-dominant hands, and last, to compare the handgrip between different ages of juvenile tennis player athletes. 137 male and 45 female tennis players (aged between 8 and 18 years) participated in the study. In order to assess HS following the Eurofit and ASHT recommendations, a Jamar dynamometer was used. None of the athletes had any injury that could compromise tests. There was no difference in handgrip strength between Eurofit and ASHT recommendations regardless of sex. The best curve to describe the regression of HS and age for both genders was a sigmoid function. Males presented a higher slope at 11 years and females had a higher slope at 10 years. Moreover, in male athletes dominant HS presented higher values than non-dominant HS beginning at 14 years. However, for the females the asymmetry in HS did not occur for any age until 18 years.
