“…Handgrip dynamometers are also used as functional assessment tools to measure the strength of different muscles, directly related with a pathological condition, like rotator cuff strength [3]. Regarding the rehabilitation process, handgrip dynamometers are mainly used for evaluation purposes, such as tracking overall progress through rehabilitation [4] or testing the effect of a specific rehabilitation protocol targeting a problem related to grip strength like shoulder impingement syndrome [5]. Adequate handgrip strength is necessary for independent and quality daily living [6].…”

Background: Handheld dynamometers are used for diagnosis and rehabilitation at several pathologies. Grip force is essential for a person’s quality of life. Most dynamometers are not equipped with rehabilitation or training protocols, although the bibliography highlights this need. Objective: To compare the validity and reliability of Jamar and K-Force Grip dynamometers in patients with shoulder impingement syndrome and healthy people. Methods: Concurrent validity was assessed using known weights. Forty-four (44) patients and 69 healthy adults performed three maximum repetitions in random order with each hand, at each instrument. Reliability was evaluated using ICCs for each instrument separately, and between the two instruments. The differences between the two dynamometers were evaluated using repeated t-tests. Results: Concurrent validity of the two instruments did not reveal fix or proportional bias. Analyses for reliability yield high correlation coefficients for both groups with the lower one being between the two instruments r = 0.90, p < 0.05, (0.72–0.91) for the healthy group. T-tests showed that all participants had lower force values when using the K-Force Grip (p < 0.05). Conclusion: Both dynamometers were reliable in measuring hand grip strength for both groups. K-Force Grip was reliable and valid with respect to Jamar that was used as a benchmark. The different handle dimensions between the two dynamometers may be the reason for the different force values.

“…Therefore, the link between proximal stability and distal mobility could explain the relationship between handgrip strength and rotator cuff strength [31]. Several interventional studies supported this link and reported a significant increase in grip strength with increased shoulder stability [31,32].…”

“…In rehabilitation, it is widely accepted that effective muscle action on distal joints can be achieved when proximal joints are efficiently stabilized by the surrounding structures [18]. Therefore, the link between proximal stability and distal mobility could explain the relationship between handgrip strength and rotator cuff strength [31]. Several interventional studies supported this link and reported a significant increase in grip strength with increased shoulder stability [31,32].…”

Does grip strength correlate with rotator cuff strength in patients with atraumatic shoulder instability?

Aim To investigate if there is a correlation between grip strength (GS) and rotator cuff (RC) strength in patients with atraumatic shoulder instability (ASI) and to compare the relationship between these two measures with that previously published for a healthy population. Moreover, to determine if testing GS could be incorporated as a surrogate clinical assessment for RC strength in these patients. Methods A total of 20 subjects with ASI were included. Out of the 20 patients, eight presented with bilateral instability, which constituted a total of 28 atraumatic unstable shoulders (N = 28). GS was measured using a Jamar hand-dynamometer. External rotation (ER) and internal rotation (IR) strength was tested in inner and outer ranges using a hand-held dynamometer (HHD). Pearson’s correlation test was computed to investigate the relationship. Multiple linear regression was conducted to predict GS based on RC strength. Results Significant and strong positive correlations were found between GS and inner-range IR (r = 0.764, P < 0.001), inner-range ER (r = 0.611, P = 0.001), outer-range IR (r = 0.817, P < 0.001), and outer-range ER (r = 0.736, P < 0.001). A significant regression equation was found (F (4, 23) = 13.254, P < 0.001), with an R2 of 0.697 indicating that RC strength explained 69.7% of the variance in GS. Conclusions The results support the hypothesis showing that GS is strongly associated with RC strength in ASI patients. The simplicity of handgrip testing allows it to be used in clinical scenarios where sophisticated assessment tools are not available. GS is a convenient means to monitor patient progress during shoulder rehabilitation programs.
