Modified Harris Hip Score [MHHS-8]

Analysis

The Modified Harris Hip Score (MHHS-8) is an assessment tool used to evaluate hip function based on patients’ responses to questions concerning pain, mobility, and the ability to perform everyday activities. The source document specifically refers to activities such as walking and stair use.

The responses are scored and combined to produce an overall score ranging from 0 to 100. Higher scores indicate better hip function and less pain.

The MHHS can therefore provide a quantitative overview of hip status and may be useful for monitoring functional recovery following therapeutic interventions.

Objective

The main objective of the Modified Harris Hip Score is to provide a reliable and valid method for assessing hip status in patients who have undergone surgery or who experience hip-related problems.

The instrument may be used to:

• monitor progress during rehabilitation,
• identify possible complications or persistent functional problems,
• support adjustment of the treatment plan according to patient needs,
• compare the effectiveness of different surgical and non-surgical treatments.

In this way, the MHHS can serve as a useful outcome measure in both clinical practice and research, particularly when systematic follow-up of hip function is required.

Scoring

Scoring of the MHHS is based on the aggregation of patients’ responses across different categories related to hip function and overall hip status. Each question has specific scoring criteria, and the individual scores are added together to generate the final score.

The total score ranges from:

0 to 100 points

Higher scores indicate better hip function and less pain, whereas lower scores reflect greater functional limitation and symptom burden.

According to the source document, scores may also be classified into categories such as:

Poor
Fair
Good
Excellent

However, the source does not provide the exact numerical thresholds for these categories, so specific cut-off values should not be assigned without additional documentation.

Use of Results

MHHS results may be used to evaluate a patient’s functional status at different time points and to compare outcomes before and after therapeutic or surgical interventions.

In research settings, the total score may be used in descriptive analyses, comparisons between groups, and investigations of associations between hip function and other clinical or demographic variables.
