“…To provide some context, the minimal detectable change previously observed for a HHD when assessing neck strength is approximately 2.1 to 3.8 kgf. 35 This detectable change is smaller than the mean bias observed in this study, meaning a change is unlikely to be detected when the HHD and MHHD are used interchangeably and that some rehabilitation programmes may be deemed ineffective or that a reduction in strength of less than 2.1 kgf is not considered meaningful.…”

“…7 That said, the overall mean bias was reduced and equal to, or lower than, the minimal detectable changes previously noted. 35 This suggests that the HHD and MHHD can be used interchangeably when the correction equations are applied. When considering the 95% LOA for the same variables noted earlier, narrower limits were observed, with the scores on the HHD ranging from 14.0 to 21.8 kgf for extension and 15.9 to 24.1 kgf for flexion when compared to the MHHD, respectively.…”

Objectives: The main objective of this study was to determine the concurrent validity between a hand-held (HHD) and mounted hand-held dynamometer (MHHD) for assessing isometric neck strength.Design: Observational design. Setting: UK-based semiprofessional rugby clubParticipants: Nineteen semi-professional rugby players (age = 26 ± 5 years, stature = 186.5 ± 6.5 cm, body mass = 98.7 ± 12.8 kg).Main outcome measures: Concurrent validity (i.e., limits of agreement, correlation) between HHD and MHHD, the intrarater reliability (intra-class correlation, ICC) and comparison between playing positions.Results: Absolute peak and mean peak force were systematically lower when using the HHD compared to MHHD, with the mean bias ranging from -1.8 to -3.8 kgf (P <0.05). Differences were not evident for flexion when applying the correction equations (-0.5 to 2.1 kgf, P >0.05) but remained for extension. Correlations between methods were large-to-very large; the ICCs for both methods were good (ICC = 0.72-0.89), with no difference between positions (P >0.05). Conclusion:The concurrent validity of HHD was considered acceptable when compared to the MHHD and the correction equation was applied. Both methods are reliable and useful for assessing neck strength in rugby players, though, caution is needed when determining strength during neck extension.

“…Both intra-rater and inter-rater reliability were excellent (ICCs=0.88 -0.97) similar to that of our study. 20 A study by Tarca BD investigated the reliability of HHD for assessing isometric abdominal flexion strength. 35 participants were recruited for test-test reliability on subsequent days.…”

Objective: To determine intra-rater and inter-rater reliability of hand-held dynamometer for assessing isometric lumbar muscle strength in asymptomatic healthy population. Methods: It was a cross-sectional study conducted at the department of physiotherapy, University of Lahore Teaching Hospital, Lahore, Pakistan, from July 2020 to August 2020 through non probability-purposive sampling technique. Thirty healthy subjects were tested at thirty-degree lumbar flexion and zero-degree lumbar extension positions. Two raters assessed isometric strength of lumbar flexor and extensor muscles, by a hand-held dynamometer. Strength was measured and recorded by each of the two raters and re-assessed after a week. Correlation and pairwise comparison were done between readings. ICC values were calculated for the assessment of isometric lumbar muscle strength using handheld dynamometer. Results: A total of 30 healthy subjects had participated with mean age of 22.84±1.21 years, height 174.33±6.83 cm, weight 68.58±5.08 kg and BMI 22.52±0.35. Findings showed an excellent intra-rater (ICC 2, k = 0.95 to 0.97) and inter-rater (ICC 2, k = 0.94 to 0.95) reliability. Conclusions: Hand held dynamometer demonstrated an excellent intra- and inter-rater reliability for assessment of isometric lumbar muscles strength of healthy subject at clinical setting as it is simple to use, portable and cost-effective for the precise measurement of lumbar muscles strength. doi: https://doi.org/10.12669/pjms.37.2.3621 How to cite this:Tanveer F, Arslan SA, Darain H, Ahmad A.

“…The near-effects were quantified through commonly used clinical tests and measurements, described in Table 2 . These outcomes were chosen because they have been used in research to measure various domains of sensorimotor and neuromotor control and have demonstrated clinical usefulness and psychomotor soundness [ 5 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ].…”

A burgeoning area of innovation in sports is the use of extended realities to provide athletes with novel training environments. Evidence has demonstrated that virtual environments can be useful therapeutic tools with demonstrated positive outcomes. The purpose of this pilot investigation was to determine the effects of virtual immersive sensorimotor training intervention by quantifying 1) the training effect measured via change in performance pre-to post-intervention on the virtual reality exercises, 2) the difference in the in clinical measures of functional sensorimotor control, 3) the injury incidence rate, and 4) on-field performance during soccer competitions. Statistical analyses were used to describe differences between an experimental and a control group. Participants were recruited from the men and women's soccer teams at two universities in the United States. Participants at one university were in the experimental group (n = 78) and received virtual immersive sensorimotor training, consisting of nine novel exercises in headset virtual reality, twice each week for six weeks. Participants at the second university were in the control group (n = 52). The virtual exercises were developed with reference to the rehabilitative principles of neuroplasticity to train various neurologic processes, contributing to overall sensorimotor control. This includes vestibular, visual and oculomotor activities, cervical neuromotor control training, movement coordination, and postural/balance exercises. The results indicate significant positive training effects pre-to post-intervention in seven of the nine training exercises (p ≤ 0.005) and improvement in clinical tests of cervical neuromotor control, balance, and inspection time (p ≤ 0.009) in the experimental group compared to the control. One of the virtual training exercises was positively associated with on-field performance (p = 0.022). No differences in injury rate or overall on-field performance metrics between the experimental and control were detected. This research study provides evidence of training and positive transfer from virtual to real-world environments, supporting the use of these novel virtual exercises to improve measures of sensorimotor control in healthy soccer athletes.
