Non-Specific Patient Population

Cerebral Palsy

7 subtests, performed on both non-dominant and dominant hands:
1) Writing a 24-letter, 3rd grade reading level difficulty sentence
2) Turning over 3x5-inch cards
3) Picking up small common objects (e.g. pennies, paper clips, bottle caps) and placing them in a container
4) Stacking checkers
5) Simulated feeding
6) Moving light objects (e.g. empty cans)
7) Moving heavy objects (e.g. 1lb weighted cans)
Subtest score = time (seconds) to complete task
Total score = sum of times for each subtest
Maximum time allotted per subtest is 120 seconds
Lower score = greater function
Each item performed with each hand separately – non-dominant hand first.
Measures unilateral hand function.
Assesses speed, not quality of performance.

Considerations

Bovend’ Eerdt et al 2004 reports validity and reliability of a modified Jebsen Test (3 of the subtest combined into 1 test).
Assesses hand function with understanding that proximal upper extremity function will influence ability to place and position the hand. Proximal weakness and forearm rotation limitations may influence hand function outcomes.
Jebsen is not recommended for use in hand neuroprosthesis outcomes for individuals with C5 tetraplegia.
May not detect changes of intrinsic hand muscles and allows for compensatory trunk and shoulder movement to complete tasks.

Excellent Test-Retest Reliability for all subtests for dominant hand except writing (r = 0.91-0.99) and non-dominant hand except feeding and large, light objects (r = 0.78-0.92)
Adequate Test-Retest Reliability for dominant hand writing (r = 0.67) and non-dominant hand feeding (r = 0.60) and large light objects (r = 0.67)
Absent practice effect (p < 0.05)

Correlation Coefficients for Test-Retest Reliability

Test	Dominant Hand	Non-dominant Hand
Writing	0.67	0.84
Card turning	0.91	0.78
Small, common object	0.93	0.85
Simulated Feeding	0.92	0.60
Checkers	0.99	0.91
Large, light objects	0.89	0.67
Large, heavy objects	0.89	0.92

All significant at the p < 0.01 level

Healthy individuals: (Sığırtmaç, İ. C., & Öksüz, Ç., 2019)

Excellent test-retest reliability for both dominant and nondominant hand
- Dominant hand, total score: (ICC = 0.95)
- Non-dominant hand, total score: (ICC = 0.89)
Acceptable test-retest reliability for lifting large light object with dominant hand (ICC = 0.77)

Interrater/Intrarater Reliability

Normal:

(Hackel et al,1992)

Excellent Intra-rater reliability (r = 0.84 and 0.85, p < 0.05) for 2 raters
Excellent Inter-rater reliability (ICC = 0.82 – 1.00)

Criterion Validity (Predictive/Concurrent)

Status Post Hand Surgery:

(Davis Sears and Chung, 2010; n = 111 (RA n = 37, OA n = 10, CTS n = 18, and Fx n = 46); evaluated preoperatively and 9-12 months post op; Michigan Hand Function Test (MHQ) used as reference standard)

Poor correlation with MHQ total scores for RA, OA, CTS, Fx (r =0.19, 0.04, 0.59, 0.36, respectively)
Poor correlation with MHQ subtests(ADL, function, work, satisfaction) for RA, OA, Fx (r = 0.10-0.41) and CTS for work & satisfaction (r = 0.38, 0.56 respectively)
Adequate correlation moderate for CTS for ADL and function (r = 0.68, 0.69, respectively)

Construct Validity

Discriminant validity:

(Davis Sears and Chung, 2010)

Poor discriminative validity for predicting positive or negative outcomes in hand function as measured by the MHQ outcomes (positive = change in MHQ score > 20; negative = change in MHQ score ≤ 20) for RA, OA, CTS, and Fx (ROC area under curve = 0.52, 0.58, 0.66, 0.59, respectively)
Poor discriminative validity for discriminating individuals with high or low MHQ scores (high = MHQ >75; low = MHQ ≤ 75) for RA, OA, and CTS all conditions except distal radius fracture (ROC area under curve = 0.48, 0.0, 0.65, respectively with 95% CI)
Adequate discriminative validity for determining high versus low score on MHQ (ROC area under curve = 0.76), indicating a 76% probability of predicting high or low test score on the MHQ

Convergent validity:

Patients with Hand Injuries: (Sığırtmaç, İ. C., & Öksüz, Ç., 2019)

Adequate convergent validity of JTHFT total score with DASH-T score for injured hand (r = 0.39) and uninjured hand (r = 0.35)
Adequate convergent validity of JTHFT total score with grip strength of injured hand (r = -0.33) for injured hand total score
Poor convergent validity of JTHFT total score with grip strength of injured hand (r = -0.21) for non-injured hand total score)
Poor convergent validity with grip strength of uninjured hand (r = -0.03) for injured hand score, r = -0.03 for non-injured hand score)

Responsiveness

Effect Size:

(Davis Sears & Chung, 2010)

Small change for CTS (ES = 0.05)
Moderate change for Fx, RA, and OA (ES = 0.35, 0.47, 0.67, respectively)
Effect size was greater for detecting change in and hand function following hand surgery using the MHQ (0.74-1.30) for all groups than Jebsen

Standard Error of Measurement (SEM)

Excellent: Cronbach’s alpha = 0.96* for the dominant hand.
Excellent: Cronbach’s alpha = 0.92* for the non-dominant hand.

*Scores higher than 0.9 may indicate redundancy in the scale questions.

Criterion Validity (Predictive/Concurrent)

Chronic Stroke (Berardi et al., 2019; JTHFT-IT)

Concurrent validity (dynamometer): Pearson’s coefficient showed statistically significant values, mainly for the dominant hand.

  - Adequate correlation for writing a short sentence (r = -0.48)
- Dominant hand:
  - Adequate correlation for turning over a card (r = -0.34), picking up small objects (r = -0.44), simulated feeding (r = -0.46), stacking checkers (r = -0.46), picking up large light cans (r = -0.40), and picking up large heavy cans (r = -0.40).
  - Poor correlation for writing a short sentence (r = -0.25).

Construct Validity

Chronic Stroke (Berardi et al., 2019; JTHFT-IT)

Construct validity (WMFT-IT-TIME): Pearson’s coefficient showed statistically significant values, mainly for items relating to the arm and hand (items 9-16) of the dominant hand.

Significant difference between Test 1 and Test 2 for the more affected hand (t = -4.673, p < 0.001)
Moderate changes on the more affected hand (effect size = 0.472)
Small changes on the less affected hand (effect size = 0.049)

Group approach by age:

Large changes on more affected hand for younger (age 5-10 years) age group (n = 56, effect size = 0.502, p < 0.001)
Moderate changes on more affected hand for older (age 11-17) age group (n = 31, effect size = 0.432, p = 0.002)

Group analysis by topography:

Moderate changes in the more affected hand for unilateral impairments (n = 70, effect size = 0.489, p = 0.001)
Large changes on the more affected hand for bilateral impairments (n = 17, effect size = 0.594, p = 0.005)

Standard Error of Measurement (SEM)

Muscular Dystrophy: (Artilheiro et al., 2018; n = 50; Mean age (SD) = 20.8 (4.96) years; Brazilian sample)

Jebsen-Taylor Hand Function Test Subtest (Hand)	SEM
1 ND (Non-Dominant)	4.20
1 D (Dominant)	0.00
2 ND	0.41

Interrater/Intrarater Reliability

Muscular Dystrophy: (Artilheiro et al., 2018) Excellent interrater reliability for all subtests: (ICC = 0.772-1.000):
Jebsen-Taylor Hand Function Test Subtest (Hand)	ICC
1 ND (Non-Dominant)	0.772
1 D (Dominant)	1.000
2 ND	0.998
2 D	0.997
3 ND	0.983
3 D	0.903
4 ND	0.999
4 D	0.999
5 ND	0.997
5 D	0.992
6 ND	0.999
6 D	0.995

Internal Consistency

Muscular Distrophy: (Artilheiro et al., 2018)

Excellent internal consistency (Cronbach’s alpha = 0.98)
